Patients were grouped by oropharyngeal cancer (OPC) and non-OPC (oral cavity cancer), type, and the length of Medicaid enrollment. We also assessed if the effect of dropping dental benefits varied by the number of dentists per capita.</p></section><section class="article-section__content" id="cam47061-sec-0003" style="box-sizing: border-box; font-size: 1rem; line-height: 1.5; margin: 0px; position: relative; scroll-margin-top: 4.0625rem;"><h3 class="article-section__sub-title section1" id="cam47061-sec-0003-title" style="box-sizing: border-box; color: #1f1f1f; font-family: "open sans", Arial, icomoon, sans-serif; font-size: 22px; font-weight: 400; line-height: 1.2; margin-bottom: 12px; margin-top: 12px; scroll-margin-top: 4.0625rem;">Results</h3><p style="box-sizing: border-box; margin-bottom: 16px; margin-top: 0.3125rem;">Dropping Medicaid dental benefits was associated with a 6.5%-point decline in early-stage diagnoses of non-OPC (95% CI = −14.5, −3.2, <i style="box-sizing: border-box;">p</i> = 0.008). This represented a 20% relative reduction from baseline rates. The effect was highest among beneficiaries with 3 months of continuous Medicaid enrollment prior to diagnosis who resided in counties with more dentists per capita.

Alternative approaches are needed to prevent advanced stage OPC.</p></section></div>Marty Jablow DMDhttp://www.blogger.com/profile/04707771108394492539noreply@blogger.com0tag:blogger.com,1999:blog-9059476.post-40622535115915815972024-03-12T14:11:00.010-04:002024-03-12T14:11:07.873-04:00Beta-defensin index: A functional biomarker for oral cancer detection<p> </p><h2 class="top" data-left-hand-nav="Summary" id="secsectitle0010" style="-webkit-text-size-adjust: 100%; box-sizing: border-box; font-family: helvetica, sans-serif; font-size: 2.25rem; line-height: 1.1; margin-bottom: 1.25rem; margin-top: 3.4375rem;" tabindex="-1"><span class="top__text" style="box-sizing: border-box;"><div class="separator" style="clear: both; text-align: center;"><span class="bulleted" style="box-sizing: border-box; caret-color: rgb(255, 255, 255); font-size: 16px; font-weight: 400; text-align: start;"><span style="box-sizing: border-box;"><span class="article-header__access" style="box-sizing: border-box; text-transform: capitalize;"><br /></span></span></span></div><div class="separator" style="clear: both; text-align: center;"><span class="bulleted" style="box-sizing: border-box; caret-color: rgb(255, 255, 255); font-size: 16px; font-weight: 400; text-align: start;"><span style="box-sizing: border-box;"><span class="article-header__access" style="box-sizing: border-box; text-transform: capitalize;">Cell Reports Mediine Access</span></span></span><span class="article-header__publish-date bulleted" style="box-sizing: border-box; caret-color: rgb(255, 255, 255); display: inline-block; font-size: 16px; font-weight: 400; margin-bottom: 0.625rem; text-align: start;"><span class="article-header__publish-date__label" style="box-sizing: border-box; margin-right: 0.3125rem;">Published:</span><span class="article-header__publish-date__value" style="box-sizing: border-box;">March 04, 2024</span></span><span class="article-header__doi bulleted" style="box-sizing: border-box; caret-color: rgb(255, 255, 255); display: inline-block; font-size: 16px; font-weight: 400; margin-bottom: 0.625rem; text-align: start;"><span class="article-header__doi__label" style="box-sizing: border-box; margin-right: 0.3125rem;">DOI:</span><a class="article-header__doi__value" href="https://doi.org/10.1016/j.xcrm.2024.101447" style="border-bottom-color: rgba(255, 255, 255, 0.2); border-bottom-style: solid; border-bottom-width: 0.125rem; box-sizing: border-box; cursor: pointer; text-decoration: none;">https://doi.org/10.1016/j.xcrm.2024.101447</a></span></div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/a/AVvXsEjYNyXBBLRyYWEsecjmbSaqgFVx9YYwU2VUOp6UBm_TcjGUU2IsTnRHa0k4Mbse2VEg_kj7FMZgR_iEEd0yURAll98FNT7x6SZZM9ThoEcTdBxi5MgsdF9zWSQcDn1TbmzICf6ZVWnguytME7XaNnczDVvsu92GmRsAy7iOvnfqd53pHZq3YlMW5g" style="margin-left: 1em; margin-right: 1em;"><img alt="" data-original-height="375" data-original-width="375" height="240" src="https://blogger.googleusercontent.com/img/a/AVvXsEjYNyXBBLRyYWEsecjmbSaqgFVx9YYwU2VUOp6UBm_TcjGUU2IsTnRHa0k4Mbse2VEg_kj7FMZgR_iEEd0yURAll98FNT7x6SZZM9ThoEcTdBxi5MgsdF9zWSQcDn1TbmzICf6ZVWnguytME7XaNnczDVvsu92GmRsAy7iOvnfqd53pHZq3YlMW5g" width="240" /></a></div></span></h2><h2 class="top" data-left-hand-nav="Summary" id="secsectitle0010" style="-webkit-text-size-adjust: 100%; box-sizing: border-box; font-family: helvetica, sans-serif; font-size: 2.25rem; line-height: 1.1; margin-bottom: 1.25rem; margin-top: 3.4375rem;" tabindex="-1"><span class="top__text" style="box-sizing: border-box;">Summary</span></h2><div class="section-paragraph" style="-webkit-text-size-adjust: 100%; box-sizing: border-box; caret-color: rgb(80, 80, 80); color: #505050; font-family: helvetica, sans-serif; font-size: 18px; margin-bottom: 1.125rem; margin-top: 0.625rem;"><div class="section-paragraph" style="box-sizing: border-box; margin-bottom: 1.125rem; margin-top: 0.625rem;">There is an unmet clinical need for a non-invasive and cost-effective test for oral squamous cell carcinoma (OSCC) that informs clinicians when a biopsy is warranted. Human beta-defensin 3 (hBD-3), an epithelial cell-derived anti-microbial peptide, is pro-tumorigenic and overexpressed in early-stage OSCC compared to hBD-2. We validate this expression dichotomy in carcinoma <em style="box-sizing: border-box;">in situ</em> and OSCC lesions using immunofluorescence microscopy and flow cytometry. The proportion of hBD-3/hBD-2 levels in non-invasively collected lesional cells compared to contralateral normal cells, obtained by ELISA, generates the beta-defensin index (BDI). Proof-of-principle and blinded discovery studies demonstrate that BDI discriminates OSCC from benign lesions. A multi-center validation study shows sensitivity and specificity values of 98.2% (95% confidence interval [CI] 90.3–99.9) and 82.6% (95% CI 68.6–92.2), respectively. A proof-of-principle study shows that BDI is adaptable to a point-of-care assay using microfluidics. We propose that BDI may fulfill a major unmet need in low-socioeconomic countries where pathology services are lacking.</div></div>Marty Jablow DMDhttp://www.blogger.com/profile/04707771108394492539noreply@blogger.com0tag:blogger.com,1999:blog-9059476.post-24214188605757375682024-03-11T09:53:00.000-04:002024-03-11T09:53:00.144-04:00Tooth loss during supportive periodontal care: A prospective study <p> </p><div class="article-citation">

Abstract
</h2>
<div class="abstract-content selected" id="eng-abstract">
<p>
<strong class="sub-title">
Aim:
</strong>
To assess periodontal stability and the association between tooth-
and patient-related factors and tooth loss during supportive
periodontal care (SPC).
</p>
<p>
<strong class="sub-title">
Materials and methods:
</strong>
A prospective observational study was carried out on previously
treated periodontitis patients followed up for 5 years in SPC. The risk
profile (low, moderate, high) of each patient based on periodontal risk
assessment (PRA) scoring at baseline was evaluated, and tooth loss rates
were analysed.
</p>
<p>
<strong class="sub-title">
Results:
</strong>
Two hundred patients were included in the study, and 143 had
5-year follow-up data available for analysis. The overall annual tooth
loss per patient was 0.07 ± 0.14 teeth/patient/year. Older age, smoking,
staging and grading were associated with increased tooth loss rates.
Most patients whose teeth were extracted belonged to the PRA high-risk
group. Both PRA and a tooth prognosis system used at baseline showed
high negative predictive value but low positive predictive value for
tooth loss during SPC.
</p>
<p>
<strong class="sub-title">
Conclusions:
</strong>
Overall, the tooth loss rate of periodontitis patients in this
prospective cohort study under SPC in private practice was low. Both
tooth-based and patient-based prognostic systems can identify high-risk
cases, but their positive predictive value should be improved.

is a blooming trend in the application of robotic surgery in oral and
maxillofacial care, and different studies had evaluated the quality of
life (QoL) outcomes among patients who underwent robotic surgery in the
oral and maxillofacial region. However, empirical evidence on the QoL
outcomes from these procedures is yet to be mapped. Thus, this study was
conducted to evaluate the available scientific evidence and gaps
concerning the QoL outcomes of patients treated with robotic surgery in
the oral and maxillofacial region.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Methods</h3><p>This
study adopted a scoping review design, and it was conducted and
reported based on the Arksey and O’Malley, PRISMA-ScR, and AMSTAR-2
guidelines. SCOPUS, PubMed, CINAHL Complete, and APA PsycINFO were
searched to retrieve relevant literature. Using Rayyan software, the
retrieved literature were deduplicated, and screened based on the
review’s eligibility criteria. Only the eligible articles were included
in the review. From the included articles, relevant data were charted,
collated, and summarized.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Results</h3><p>A
total of 123 literature were retrieved from the literature search.
After deduplication and screening, only 18 heterogeneous original
articles were included in the review. A total of 771 transoral robotic
surgeries (TORSs) were reported in these articles, and the TORSs were
conducted on patients with oropharyngeal carcinomas (OPC), recurrent
tonsillitis, and obstructive sleep apnoea (OSA). In total, 20 different
QoL instruments were used in these articles to assess patients’ QoL
outcomes, and the most used instrument was the MD Anderson Dysphagia
Inventory Questionnaire (MDADI). Physical functions related to
swallowing, speech and salivary functions were the most assessed QoL
aspects. TORS was reported to result in improved QOL in patients with
OPC, OSA, and recurrent tonsillitis, most significantly within the first
postoperative year. Notably, the site of the lesion, involvement of
neck dissections and the characteristics of the adjuvant therapy seemed
to affect the QOL outcome in patients with OPC.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Conclusion</h3><p>Compared
to the conventional treatment modalities, TORS has demonstrated better
QoL, mostly in the domains related to oral functions such as swallowing
and speech, among patients treated with such. This improvement was most
evident within the initial post-operative year.</p></div></div></section>Marty Jablow DMDhttp://www.blogger.com/profile/04707771108394492539noreply@blogger.com0tag:blogger.com,1999:blog-9059476.post-181694149092839572024-03-06T09:54:00.003-05:002024-03-06T09:54:00.142-05:00Comprehensive analysis of the maxillary esthetic zone for immediate implant placement using cone beam computed tomography: A study of 352 maxillary images<p> </p><div class="inline-it"><span class="article-header__publish-date bulleted"><span class="article-header__publish-date__label">Published:</span><span class="article-header__publish-date__value">February 27, 2024</span></span><span class="article-header__doi bulleted"><span class="article-header__doi__label">DOI:</span><a class="article-header__doi__value" href="https://doi.org/10.1016/j.prosdent.2024.02.004">https://doi.org/10.1016/j.prosdent.2024.02.004</a></span></div><h2 class="top" data-left-hand-nav="Abstract" id="secsect0005" tabindex="-1"><span class="top__text">Abstract</span></h2>
<div class="section-paragraph">
<h3>Statement of problem</h3>
<div class="section-paragraph">Previous studies have examined the maxillary esthetic zone for immediate implant placement,
but these studies had small sample sizes and did not investigate multiple parameters.</div>
<h3>Purpose</h3>
<div class="section-paragraph">The purpose of this cross-sectional study was to use cone beam computed tomography
(CBCT) to evaluate the sagittal root position (SRP), alveolar bone concavity, labial
bone perforation (LBP), and tooth-ridge angle in the maxillary anterior teeth region.</div>
<h3>Material and methods</h3>
<div class="section-paragraph">A total of 352 CBCT images of patients (180 men and 172 women) who visited the dental
hospital between 2018 and 2023 were analyzed. The sample included 2112 anterior maxillary
teeth. SRP, alveolar bone concavity, tooth ridge angle, and LBP were assessed using
virtual implant simulation. The data were analyzed by using chi-squared and kappa
tests to analyze distributions, independence, and dependence, <em>t</em> tests to assess sex and tooth-specific differences, and the Spearman correlation
test to explore potential correlations (α=.05).</div>
<h3>Results</h3>
<div class="section-paragraph">The CBCT images revealed that the majority of SRP were in Class I (85.4%), with smaller
percentages in Class II (12.5%) and Class IV (2.3%); Class III was the least common
(1%). The canine exhibited the most significant alveolar bone concavity angle average
(149.14 ±6.35 degrees), followed by the lateral incisor (142.32 ±8.7 degrees). The
canines had the highest occurrence of LBP (63.1%) (<em>P</em><.01). Women had a higher frequency of labial bone perforation and deeper alveolar
bone concavities than men (<em>P</em><.01).</div>
<h3>Conclusions</h3>
<div class="section-paragraph">The findings of this study indicate that careful assessment and planning are necessary
for immediate implant placement in the maxillary anterior region. The significant
occurrence of LBP highlights the importance of thorough planning and evaluation to
avoid surgical mishaps and complications which may necessitate bone grafting and result
in added costs and time. Special attention should be given to women and the canine
area.</div>

<div class="section-paragraph">
<h3>Statement of problem</h3>
<div class="section-paragraph">Infiltrated resin has been widely used as a minimally invasive approach to masking
white spot lesions and reinforcing demineralized enamel. Recent evidence confirms
its satisfactory effect in the short term, but studies focusing on its long-term performance
are lacking.</div>
<h3>Purpose</h3>
<div class="section-paragraph">The purpose of this ex vivo study was to evaluate the durability of infiltrated resin
on white spot lesions after pH cycling and long-term thermocycling, staining, and
toothbrushing.</div>
<h3>Material and methods</h3>
<div class="section-paragraph">Four axial surfaces of 25 extracted human molars were sectioned and fabricated as
specimens. The enamel surface of each specimen was prepared in 3 areas: sound enamel,
demineralized enamel (white spot lesions), and demineralized enamel treated by infiltrated
resin. Then, 4 specimens of each molar were allocated to different challenges simulating
a 10-year follow-up: pH cycling, thermocycling, staining, and toothbrushing. The surface
roughness, microhardness, and CIELab color values were measured before and after different
treatments. A scanning electron microscope (SEM) was used to observe representative
specimens. Linear mixed models were used to evaluate the effect of different treatments
on microhardness, roughness, and color differences (ΔE) (α=.05).</div>
<h3>Results</h3>
<div class="section-paragraph">Resin infiltration reduced the surface roughness and increased the microhardness of
demineralized lesions, (<em>P</em><.001) but the values of sound enamel at baseline were not reached. The pH cycling
led to the greatest roughness values (515.6 ±56.9 nm) on resin-infiltrated lesions,
followed by thermocycling (450.7 ±64.7 nm), toothbrushing (291.2 ±43.5 nm), and staining
(183.6 ±49.3 nm) (all <em>P</em><.001). Only pH cycling significantly decreased the microhardness of resin-infiltrated
lesions (81.6 ±14.8 HV 0.2) after progressive demineralization (<em>P</em><.001). No clinically identified differences were found between resin-infiltrated
white spot lesions and sound enamel (ΔE=3.4 ±2.0) at baseline. However, resin-infiltrated
lesions demonstrated significantly greater discoloration after pH cycling (ΔE=8.0
±4.5, <em>P</em><.001), thermocycling (ΔE=5.4 ±2.0, <em>P</em>=.014), and staining treatments (ΔE=10.4 ±3.2, <em>P</em><.001) than sound enamel.</div>
<h3>Conclusions</h3>
<div class="section-paragraph">Infiltrated resin application reduced surface roughness, improved microhardness, and
masked white spot lesions immediately. However, it could not reestablish the characteristics
of sound enamel completely and resist chemical and mechanical challenges over time.</div>

Abstract
</h2>
<div class="abstract-content selected" id="eng-abstract">
<p>
Food and fluid supply is fundamental for optimal athletic
performance but can also be a risk factor for caries, dental erosion,
and periodontal diseases, which in turn can impair athletic performance.
Many studies have reported a high prevalence of oral diseases in elite
athletes, notably dental caries 20-84%, dental erosion 42-59%,
gingivitis 58-77%, and periodontal disease 15-41%, caused by frequent
consumption of sugars/carbohydrates, polyunsaturated fats, or deficient
protein intake. There are three possible major reasons for poor oral
health in athletes which are addressed in this review: oxidative stress,
sports diet, and oral hygiene. This update particularly summarizes
potential sports nutritional effects on athletes' dental health.
Overall, sports diet appropriately applied to deliver benefits for
performance associated with oral hygiene requirements is necessary to
ensure athletes' health. The overall aim is to help athletes, dentists,
and nutritionists understand the tangled connections between sports
diet, oral health, and oral healthcare to develop mitigation strategies
to reduce the risk of dental diseases due to nutrition.

Abstract
</h2>
<div class="abstract-content selected" id="eng-abstract">
<p>
<strong class="sub-title">
Background:
</strong>
Examination of serial cross-sectional national surveys from a
representative sample of the population can identify patterns and help
support policy development.
</p>
<p>
<strong class="sub-title">
Methods:
</strong>
The authors used data from the National Health Interview Survey on
US adults reporting a dental visit in the past 12 months to examine
trends from 1997 through 2019. Groups analyzed were based on
sociodemographic factors including residence in a metropolitan
statistical area, race and ethnicity, family income level, and
geographic region.
</p>
<p>
<strong class="sub-title">
Results:
</strong>
Over the 23-year period, the authors found differences for family
income level, living in a rural (nonmetropolitan vs metropolitan) area,
race and ethnicity, and geographic region (P < .0001). When
stratified by family income, racial disparities have diminished. Gaps in
dental service use are long-standing for rural nonmetropolitan
communities.
</p>
<p>
<strong class="sub-title">
Conclusions:
</strong>
Relative to urban locales, rural communities experienced
persistent disparities in the use of the oral health care delivery
system throughout the 23 years measured. Strategies to create innovative
models of care are needed to address oral health needs in underserved
rural communities.
</p>
<p>
<strong class="sub-title">
Practical implications:
</strong>
Policy is needed to foster a shift toward population health that
will incentivize a health care system that reduces financial barriers
and enhances health outcomes for adult oral health, especially for rural
areas.

Group 1: diode laser 445 nm, 320 µm fiber, 0.5W, continuous wave mode, <i>dose 53 J/cm</i><sup><i>2</i></sup><i>.</i> Group 2: diode laser 970 nm, 320 µm fiber, 1W, continuous wave mode<i>, dose 106.10 J/cm</i><sup><i>2</i></sup><i>.</i> Group 3: diode laser 940 nm, bleaching handpiece, 7W, continuous wave mode, <i>dose 105 J/cm</i><sup><i>2</i></sup><i>.</i> Group 4: diode laser 940 nm, 300 µm fiber, 2W, continuous wave mode, dose <i>47.16 J/cm</i><sup><i>2</i></sup><i>.</i>
Group 5: bleaching process without laser activation. In groups 1, 2 and
5, teeth were bleached with Perfect Bleach Office + and in groups 3 and
4, LaserWhite20 bleaching gel was used. Tooth color was determined
immediately after the bleaching process using a spectrophotometer. Color
change data on the CIE <i>L</i> * <i>a</i> * <i>b</i>* system was
analyzed statistically by the one-way ANOVA and Tukey’s HSD test. All
bleaching procedures resulted in a change of color. All laser groups (∆<i>E </i>* <i>ab</i> > 3) have statistically larger ∆<i>E</i> * <i>ab</i> values than the control group (∆<i>E</i> * <i>ab</i> = 0.73) (<i>p</i> < 0.05). The diode laser 445 nm has the largest ∆<i>E</i> * <i>ab</i> value (∆<i>E</i> * <i>ab</i> = 4.65)
and results in a significantly higher color difference than all other
groups. In terms of color score difference in VITA Shades, all
laser-activated groups lead to a lightening effect while the control
group leads to only a slight lightening effect. The diode laser 445 nm
produced the greatest color difference. Laser-activated bleaching is
more effective than conventional bleaching without light activation. The
diode laser 445 nm performs best in this in vitro study.</p></div></div></section>Marty Jablow DMDhttp://www.blogger.com/profile/04707771108394492539noreply@blogger.com0tag:blogger.com,1999:blog-9059476.post-70580703488002974102024-02-21T10:24:00.007-05:002024-02-21T10:24:00.259-05:00A scoping review of dental practitioners’ perspectives on perceived barriers and facilitators to preventive oral health care in general dental practice<p> </p><p class="c-article-info-details" data-container-section="info">

health has an important role in the general health and well-being of
individuals. Dental teams are ideally placed to support patients in
preventing ill-health. Understanding the barriers and facilitators to
the adoption, promotion and facilitation of preventive advice and
treatment is key to improving oral health services. The Theoretical
Domains Framework (TDF) is a useful psychological framework to help
identify individual, interpersonal and environmental issues which could
be impacting clinicians’ ability to provide preventive advice and care.
The aim of this review was to identify the perceived barriers and
facilitators to preventive oral health care from the perspectives of the
oral healthcare team within the general dental practice.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Methods</h3><p>A
search strategy was developed, piloted, and run in: Medline via Ovid,
PsycInfo, Web of Science, SCOPUS, EMBASE, Conference Proceedings
Citation Index- Science, Cochrane Central Register of Controlled Trials
and Cochrane Database of Systematic Reviews and followed PRISMA
guidelines. Identified records were screened independently by two
researchers. Data were coded using the Theoretical Domains Framework
(TDF) and analysed using narrative data synthesis.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Results</h3><p>5610
papers were identified, and 19 included in this review. Thirteen papers
focussed on dentists. Of the 106 items mapped onto the TDF, 48 were
facilitators. The domains most frequently represented were,
environmental context and resources, beliefs about consequences, social
professional role and identity, skills, beliefs about capabilities and
knowledge. Six studies focussed on dental hygienists. There were 47
items mapped onto the TDF, 18 were facilitators. The domains most
frequently represented were environmental context and resources, social
influences, beliefs about consequences and knowledge.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Conclusions</h3><p>The
review identified that the delivery of preventive activities did not
focus solely on the patient and dental professional interaction as many
previous studies have highlighted. The review found that multiple
factors influence whether prevention is delivered to patients. The
largest barrier and facilitator for the dental professionals identified
in this review was the environmental context and resources. Further
research is needed to evaluate the effectiveness of interventions that
aim to promote preventive oral health care in primary care settings to
understand whether they address the barriers identified in this review.</p></div></div></section>Marty Jablow DMDhttp://www.blogger.com/profile/04707771108394492539noreply@blogger.com0tag:blogger.com,1999:blog-9059476.post-52744692104731691612024-02-20T10:22:00.005-05:002024-02-20T10:22:00.251-05:00Ozone and laser effects on dentin hypersensitivity treatment: a randomized clinical study<p> <img alt="Journal of Endodontics" src="https://www.jendodon.com/pb-assets/ux3/logos/ha/joen-1588856210427.svg" /></p><div class="inline-it"><span class="article-header__publish-date bulleted"><span class="article-header__publish-date__label">Published:</span><span class="article-header__publish-date__value">February 18, 2024</span></span><span class="article-header__doi bulleted"><span class="article-header__doi__label">DOI:</span><a class="article-header__doi__value" href="https://doi.org/10.1016/j.joen.2024.02.007">https://doi.org/10.1016/j.joen.2024.02.007</a></span></div><h2 class="top" data-left-hand-nav="Abstract" id="secsectitle0010" tabindex="-1"><span class="top__text">Abstract</span></h2>
<div class="section-paragraph">
<h3>Objectives</h3>
<div class="section-paragraph">Evaluate and compare the clinical efficacy of diode laser and gas ozone in the treatment
of dentin hypersensitivity (DHS).</div>
<h3>Methods</h3>
<div class="section-paragraph">132 teeth from 44 patients with moderate DHS were randomised into three groups according
to a split-mouth design. In the diode laser group, the operator irradiated the superficial
dentine exposed with 808 wavelength, incremental power from 0,2 to 0,6 W, with 20
seconds of interval. In the gas ozone group, the operator applicated, using a silicon
cup, a high dose of ozone (32 g/m<sup>3</sup>) for 30 seconds. In the <span class="underline">placebo</span> group, no therapy was applicated. The subjects underwent a first evaluation of the
dentin sensitivity level (T0), directly after treatment (T1), after 3 months (T2),
and after 6 months (T3), with a cold air blast challenge and tactile stimuli. The
pain severity was quantified according to the Visual Analogue Scale (VAS). Wilcoxon
signed-rank test was utilized to scrutinize potential statistical disparities among
the treatments. Statistical significance was predetermined at p < 0.05.</div>
<h3>Results</h3>
<div class="section-paragraph">A significant decrease of DHS was observed in gas ozone group and diode laser group
immediately, after 3 and 6 months of the therapy. After 6 months from the therapy,
the sensitivity values in the teeth treated with gas ozone remain statistically lower
than those treated with diode lasers <span class="underline">(p<0.05).</span></div>
<h3>Conclusion</h3>
<div class="section-paragraph">Laser diode and gas ozone are both efficient as dentin sensitivity treatment. Ozone
maintains an invariable effectiveness after 6 months.</div>

aim to review the spectrum of biological mechanisms of mouthwashes
shown to be active against SARS-CoV-2, evidence for efficacy in
reduction of viral load, in vitro and in vivo, and the potential for
clinical benefit in use of mouthwashes in the context of COVID-19.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Recent Findings</h3><p>Numerous
studies have now been performed to establish the antiviral efficacy of
specific mouthwash ingredients against SARS-CoV-2. A combination of
biological in vitro studies and clinical studies which assess reduction
of viral load in vivo have been performed. Certain mouthwash ingredients
have been shown to have anti-SARS-CoV-2 effect, both in vitro and in
vivo, for example, by reducing viral load detectable in saliva during
acute COVID-19 infection. In addition, iron phthalocyanine, which has
antibacterial, antifungal, and antiviral properties, has been tested
using in vitro tests, cross-sectional population studies, and randomized
clinical trials to assess clinical benefit of its use in the context of
hospitalized patients with COVID-19.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Summary</h3><p>A
non-systematic search of the literature was conducted to find studies
which generally investigated the mechanisms of action of specific
mouthwash ingredients including chlorhexidine (CHX), cetylpyridinium
chloride (CPC), ethyl lauroyl arginate (ELA), hydrogen peroxide (HP),
povidone-iodine (PVP-I), and anionic phthalocyanine derivative (APD).
The terms “Coronavirus infections,” “Severe Acute Respiratory Syndrome
Coronavirus 2,” “In vitro techniques,” “Mouthwash,” and “Dentifrices”
were used to search the electronic databases. Included were full-text
articles in Portuguese, English, and Spanish that could be read online
without limitations on the publication year. In clinical investigations,
CPC has been demonstrated to lower SARS-CoV-2 viral load in saliva for
up to 6 h, chlorhexidine was shown to reduce viral load for 60 min, and
PVP-I 1% showed the ability to decrease SARS-CoV-2 for up to 3 h.
Mouthwash containing APD has shown potential for benefit in clinical
application as an adjunct to standard care in the setting of acute
COVID-19. This mouthwash ingredient has shown evidence for reducing
symptoms, length of hospital admission, need for intensive care
admission, and mortality.</p></div></div></section>Marty Jablow DMDhttp://www.blogger.com/profile/04707771108394492539noreply@blogger.com0tag:blogger.com,1999:blog-9059476.post-42632980076057876072024-02-16T15:45:00.001-05:002024-02-16T15:45:00.130-05:00The influence of oral cavity physiological parameters: temperature, pH, and swelling on the performance of denture adhesives - in vitro study<p> </p><a data-author-popup="auth-Stefan-Schwan-Aff1-Aff3" data-author-search="Schwan, Stefan" data-corresp-id="c1" data-test="author-name" data-track-action="open author" data-track-label="link" data-track="click" href="https://bmcoralhealth.biomedcentral.com/articles/10.1186/s12903-024-03967-7#auth-Stefan-Schwan-Aff1-Aff3"><svg aria-hidden="true" class="u-icon" height="16" width="16"></svg></a><a data-test="journal-link" data-track-action="journal homepage" data-track-category="article body" data-track-label="link" data-track="click" href="https://bmcoralhealth.biomedcentral.com/"><i data-test="journal-title">BMC Oral Health</i></a>

various physical and chemical conditions within the oral cavity are
hypothesized to have a significant influence on the behavior of denture
adhesives and therefore the overall comfort of denture wearers. As such,
this study aims to understand the influence of oral cavity
physiological parameters such as temperature (17 to 52 °C), pH (2, 7,
10), and denture adhesive swelling due to saliva (20–120%) on the
behavior of denture adhesives. This study further aims to emphasize the
need for a collective approach to modelling the in-situ behavior of
denture adhesives.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Methods</h3><p>Rheological
measurements were carried out using the Super Polygrip Ultra fresh
brand denture adhesive cream to evaluate its storage modulus (G´) and
loss modulus (G´´) values at a range of physiologically relevant

characterize the wide variety of conditions that occur within the oral
cavity.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Results</h3><p>Rheological
data was recorded with respect to variation of temperature, pH, and
swelling. Overall, it can be seen that the physiological conditions of
the oral cavity have an influence on the rheological properties of the
denture adhesive cream. Specifically, our data indicates that the
adhesive’s mechanical properties are weakly influenced by pH, but do
change with respect to the temperature in the oral cavity and the
swelling rate of the adhesive.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Conclusions</h3><p>Our
results suggest that the collective inter-play of the parameters pH,
temperature and swelling ratio have an influence on the behavior of the
denture adhesive. The results clearly highlight the need for developing a
multi-parameter viscoelastic material model to understand the
collective influence of physiological parameters on the performance of
denture adhesives. Multi-parameter models can also potentially be
utilized in numerically simulating denture adhesives using finite
element simulations.</p></div></div></section>Marty Jablow DMDhttp://www.blogger.com/profile/04707771108394492539noreply@blogger.com0tag:blogger.com,1999:blog-9059476.post-5733151015467628442024-02-15T15:44:00.002-05:002024-02-15T15:44:00.136-05:00Influence of glazing and aging on the marginal, axial, axio-occlusal, and occlusal fit of 3-unit monolithic zirconia restorations fabricated using additive and subtractive techniques<p> </p><div class="inline-it"><span class="article-header__publish-date bulleted"><span class="article-header__publish-date__label">Published:</span><span class="article-header__publish-date__value">February 10, 2024</span></span><span class="article-header__doi bulleted"><span class="article-header__doi__label">DOI:</span><a class="article-header__doi__value" href="https://doi.org/10.1016/j.prosdent.2024.01.010">https://doi.org/10.1016/j.prosdent.2024.01.010</a></span></div><h2 class="top" data-left-hand-nav="ABSTRACT" id="secsect0005" tabindex="-1"><span class="top__text">ABSTRACT</span></h2>
<div class="section-paragraph">
<h3>Statement of problem</h3>
<div class="section-paragraph">Studies are sparse on how glazing and aging influence the fit of additively fabricated
monolithic zirconia restorations.</div>
<h3>Purpose</h3>
<div class="section-paragraph">The purpose of this in vitro study was to assess the effect of glazing and aging on
the fit of 3-unit monolithic zirconia restorations fabricated using different techniques.</div>
<h3>Material and methods</h3>
<div class="section-paragraph">A total of 32 monolithic zirconia restorations were fabricated for a typodont model
by using 4 distinct techniques (subtractive fabrication [SF], stereolithography [SLA],
digital light processing [DLP], and lithography-based ceramic manufacturing [LCM]).
The silicone replica approach was adopted to measure the discrepancy values for premolar
and molar abutments after sintering, glazing, and 1 year of aging. The silicone replicas
were sliced into mesiodistal and buccopalatal cross-sections, and digital micrographs
of the cross-sections were made with a ×80 stereomicroscope. An inherent measuring
program was run to record the discrepancy values (µm). Repeated-measures 2-way ANOVAs
with the Bonferroni post hoc test were used to statistically analyze the acquired
data. (α=.05).</div>
<h3>Results</h3>
<div class="section-paragraph">From the repeated measures 2-way ANOVAs, both the glazing×fabrication technique and
the aging×fabrication technique interactions were not statistically significant (<em>P</em>>.05). Glazing significantly influenced premolar abutment marginal (<em>P</em>=.022) and occlusal (<em>P</em>=.007) discrepancy values, as well as molar abutment marginal discrepancy values (<em>P</em>=.047). Aging had a statistically significant effect on premolar abutment marginal
(<em>P</em>=.008) and occlusal (<em>P</em>=.011) discrepancy values, as well as molar abutment occlusal discrepancy values (<em>P</em>=.039). In both the glazing and aging data, for all areas of interest, statistically
significant differences were detected among the fabrication techniques (<em>P</em><.05). The LCM group had the lowest discrepancy values, followed by the SLA, SF, and
DLP groups.</div>
<h3>Conclusions</h3>
<div class="section-paragraph">The LCM and SLA groups outperformed the other groups in terms of fit accuracy. The
glazing and aging procedures altered the discrepancy values. The marginal discrepancy
values of all groups were below the threshold of clinical acceptability (<120 µm).</div>

objective of this study was to compare the detection of caries in
bitewing radiographs by multiple dentists with an automatic method and
to evaluate the detection performance in the absence of a reliable
ground truth.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Materials and methods</h3><p>Four
experts and three novices marked caries using bounding boxes in 100
bitewing radiographs. The same dataset was processed by an automatic
object detection deep learning method. All annotators were compared in
terms of the number of errors and intersection over union (IoU) using
pairwise comparisons, with respect to the consensus standard, and with
respect to the annotator of the training dataset of the automatic
method.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Results</h3><p>The
number of lesions marked by experts in 100 images varied between 241
and 425. Pairwise comparisons showed that the automatic method
outperformed all dentists except the original annotator in the mean
number of errors, while being among the best in terms of IoU. With
respect to a consensus standard, the performance of the automatic method
was best in terms of the number of errors and slightly below average in
terms of IoU. Compared with the original annotator, the automatic
method had the highest IoU and only one expert made fewer errors.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Conclusions</h3><p>The automatic method consistently outperformed novices and performed as well as highly experienced dentists.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Clinical significance</h3><p>The
consensus in caries detection between experts is low. An automatic
method based on deep learning can improve both the accuracy and
repeatability of caries detection, providing a useful second opinion
even for very experienced dentists.</p></div></div></section>Marty Jablow DMDhttp://www.blogger.com/profile/04707771108394492539noreply@blogger.com0
