Aim:
</strong>
To evaluate the intensity of postendodontic pain (PEP) using final
irrigation with side-vented needle (SV), EndoActivator (EA), and Ultra X
(UX) in single-visit endodontics (SVE) with F-One rotary files.
</p>
<p>
<strong class="sub-title">
Materials and methods:
</strong>
A total 150 patients indicated for endodontic treatment were
selected. Single-visit endodontics treatment was performed under local
anesthesia. For the final irrigation protocol, they were divided into
three groups: group I (SV), group II (EA), and group III (UX). The
severity of PEP was assessed using visual analogue scale (VAS) score
after 6, 12, 24, and 48 hours. Analgesics taken by patients, for pain,
were also recorded. Finally, the data were tabulated and statistically
analyzed using SPSS 20.0 software at a level of significance being 0.05.
</p>
<p>
<strong class="sub-title">
Results:
</strong>
Postendodontic pain was less in group III (UX) and group II (EA)
compared with group I (SV) at 6 and 12 hours, which is statistically
significant (<i>p</i> < 0.05). There was no statistically significant difference found after 24 hours and 48 hours.
</p>
<p>
<strong class="sub-title">
Conclusion:
</strong>
The intensity of PEP was minimum in patients treated with
EndoActivator and ultrasonic along with single rotary file systems. The
incidence of analgesic intake was similar in all three groups. How to

<strong class="sub-title">
Aim:
</strong>
The aim of this study was to assess the impact of Nd:YAG laser,
glutaraldehyde-based desensitizer (GD), or their combination on
occluding dentinal tubules.
</p>
<p>
<strong class="sub-title">
Materials and methods:
</strong>
Fifty dentin samples were obtained from non-carious human third molars and randomly divided into five groups (<i>n</i>
= 10): (1) Control group treated with 37% phosphoric acid, (2) GD
group, (3) Nd:YAG laser group (1064 nm, 100 µs, 10 Hz, 300 µm fiber, 1 W
power, 100 mJ energy, and 85 J/cm<sup>2</sup> energy density), (4) GD
followed by Nd:YAG laser group, and (5) Nd:YAG laser followed by GD
group. Scanning electron microscopy (SEM) was used to capture five
images from each sample for analysis of dentinal tubules using Image J
software. SEM/EDX elemental analysis was performed to determine the main
mineral contents. Data analyzed using one-way ANOVA and Tukey's <i>post hoc</i> test for statistical comparisons.
</p>
<p>
<strong class="sub-title">
Results:
</strong>
Laser and combination groups showed a significant decrease in
dentinal tubule counts compared with the control and GD groups (<i>p</i>
< 0.0001). There were no significant differences in open dentinal
tubule counts between the control and GD groups, as well as between the
laser and combination groups. However, significant differences were
observed in the total area, average size of the tubules, and percentage
area between the control group and the treatment groups (GD, laser, GD +
laser, laser + GD). No significant difference was found in the Ca/P
ratio between the tested groups.
</p>
<p>
<strong class="sub-title">
Conclusion:
</strong>
The use of Nd:YAG laser alone or in combination with GD was more
effective in occluding dentinal tubules compared to GD alone.
</p>
<p>
<strong class="sub-title">
Clinical significance:
</strong>
This study has shown that Nd:YAG laser alone and in combination with GD has superior dentinal tubule occlusion <i>in vitro</i>.
Its clinical use in the treatment of dentinal hypersensitivity may
overcome the drawback of conventional treatment approaches for dentin
hypersensitivity needing repeated applications to achieve continuous
relief from pain since acidic diet and toothbrushing result in the
continuing elimination of precipitates and surface coatings. How to cite

Aim:
</strong>
This report addresses the management of a large persistent
discharging lesion in an 11-year-old boy. The report describes the use
of aspiration-irrigation technique for the management of immature
necrotic tooth with persistent discharge after a failed regenerative
procedure.
</p>
<p>
<strong class="sub-title">
Background:
</strong>
Regenerative endodontics aim to provide an increase in root canal
width, length, and in apical closure. Alternative procedures, such as
apexification, should be attempted when regeneration fails. If the canal
cannot be dried to persistent discharge, the aspiration-irrigation
technique can be used. The technique relies on using aspiration along
with irrigation to remove pus from the periapical area.
</p>
<p>
<strong class="sub-title">
Case description:
</strong>
This is a case for an 11-year-old patient who had trauma to tooth
#11, which resulted in the complicated crown fracture. He had an
emergency management that included pulpectomy and intracanal medication
at another clinic. Two years later, the patient was presented to our
clinic. Upon examination, the diagnosis was previously initiated therapy
with asymptomatic apical periodontitis in immature tooth #11.
Regeneration was attempted first but failed. The mineral trioxide
aggregate (MTA) plug was removed, and the canal had persistent pus
discharge. The canal was filled with intracanal medication, and then 2
weeks later, the canal was filled with triple antibiotic paste (TAP).
Next visit, and due to continuous discharge, tooth #11 was treated
conservatively with an intracanal aspiration-irrigation technique. An
IrriFlex needle attached to a high-volume suction was used to aspirate
the cystic fluid. Mineral trioxide aggregate plug apexification was
performed in a later visit and the tooth was restored.
</p>
<p>
<strong class="sub-title">
Conclusion:
</strong>
During the 3-month and 16-month follow-up, there was resolution of
the symptoms, a decrease in the periapical lesion size, and soft
tissues appeared within normal limits.
</p>
<p>
<strong class="sub-title">
Clinical significance:
</strong>
Regenerative procedures are a good option for immature necrotic
teeth. These procedures may fail due to persistent pus discharge from
the root canals. The aspiration-irrigation technique is a good treatment
option in cases of consciously discharging canals. How to cite this

Abstract
</h2>
<div class="abstract-content selected" id="eng-abstract">
<p>
<strong class="sub-title">
Background:
</strong>
Environmental sustainability has been brought into the limelight
due to the global climate crisis. This crisis is driven by human
activities and even the healthcare sector is no exception. Within
dentistry, orthodontics is a large global market; hence, the use of
post-orthodontic retainers has a significant environmental footprint.
The aim of this study was to determine the environmental sustainability
of post-orthodontic retention using Hawley and Essix retainers.
</p>
<p>
<strong class="sub-title">
Materials and methods:
</strong>
A comparative life-cycle assessment (LCA) was carried out to
compare the environmental impact of both retainers. All inputs and
outputs were accounted for using the Ecoinvent database, v3.7.1, and
openLCA software. Sixteen impact categories were used to determine their
environmental burden.
</p>
<p>
<strong class="sub-title">
Results:
</strong>
Of the 16 impact categories, the Hawley had a greater
environmental burden than the Essix retainer in 12 categories. The
Hawley's most significant contributors to its impact values are factory
manufacturing and in-house production, with an average of 41.45% and
52.52%, respectively. For the Essix, the greatest contributor is factory
manufacturing, with an average of 64.63%. However, when factoring in
the lifespan of the retainers, the Essix would have a greater
environmental impact than the Hawley retainer.
</p>
<p>
<strong class="sub-title">
Limitations:
</strong>
This study employed a comparative LCA. There were also assumptions made, but these were supported by research.
</p>
<p>
<strong class="sub-title">
Conclusions:
</strong>
On the basis of the evidence gathered in this study, Hawley
retainers are more environmentally sustainable than Essix retainers.
These results would better enable clinicians to factor in the
environmental impact and make informed decisions on the choice of
retainer type.

study focuses on temporomandibular disorders (TMDs), which affect the
temporomandibular joint and related muscles and have multiple causes.
Recent studies have examined the connection between menstrual cycles,
estrogen levels, and TMDs, but results are inconsistent, highlighting
the need for more research. The aim is to explore the prevalence of TMDs
in pregnant women and consider how hormonal changes during pregnancy
might influence these disorders.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Methods</h3><p>In
this cross-sectional case-control study, we compared 32 pregnant women
with 35 non-pregnant women. We evaluated several TMD-related factors
such as pain levels, chronic pain classification, scores on the Jaw
Functional Limitation Scale-20 and Oral Behaviors Checklist, and
psychological health. We used various statistical methods including
descriptive statistics, chi-square tests, linear regression, and
adjustments for multiple comparisons to analyze the data.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Results</h3><p>Pregnant
women showed different pain perceptions, generally reporting less pain
and lower severity. Nonetheless, these differences were not uniform
across all TMD-related measures. Linear regression did not find a
consistent link between pregnancy and TMD scores, except for chronic
pain grade, which was not significant after adjusting for multiple
comparisons. There was a significant relationship between depression and
TMD severity, emphasizing the need to consider mental health in TMD
evaluations.</p><h3 class="c-article__sub-heading" data-test="abstract-sub-heading">Discussion</h3><p>The
findings suggest that pregnancy is neither a risk nor a protective
factor for TMD. Differences in pain perception, functional status, and
psychological health were observed in pregnant women but were not
consistent for all TMD-related aspects. The role of estrogen in TMJ
health and TMD risk is complex and requires further study. The research
highlights the necessity of including mental health, especially
depression, in TMD assessments. More comprehensive research with larger
sample sizes is essential to better understand the connections between
pregnancy, TMD, and hormones, aiming to improve TMD management in
pregnant women and others.</p></div></div></section>Marty Jablow DMDhttp://www.blogger.com/profile/04707771108394492539noreply@blogger.com0tag:blogger.com,1999:blog-9059476.post-29156683563080360332024-03-20T09:52:00.008-04:002024-03-20T09:52:00.255-04:00Fracture resistance of CAD/CAM endocrowns made from different materials in maxillary premolar interproximal defects<p> </p><section aria-labelledby="Abs1" data-gtm-vis-first-on-screen50443292_562="662" data-gtm-vis-first-on-screen50443292_563="660" data-gtm-vis-has-fired50443292_562="1" data-gtm-vis-has-fired50443292_563="1" data-gtm-vis-recent-on-screen50443292_562="662" data-gtm-vis-recent-on-screen50443292_563="660" data-gtm-vis-total-visible-time50443292_562="10000" data-gtm-vis-total-visible-time50443292_563="10000" data-title="Abstract" lang="en"><div class="c-article-section" id="Abs1-section"><div class="c-article-section__title js-section-title js-c-reading-companion-sections-item" id="Abs1" style="text-align: left;">Jin, F., Yu, X., Zhou, H. <i>et al.</i> Fracture resistance of CAD/CAM endocrowns made from different materials in maxillary premolar interproximal defects.

<div class="padding_abstract justify ltr"><strong>Objective:</strong>
This study aimed to evaluate the effect of different premedication
protocols on the success rate of the inferior alveolar nerve block
(IANB) technique in mandibular molars with irreversible pulpitis.<br /><strong>Methods: </strong>Two hundred and ten<strong> </strong>participants
were randomly assigned into three groups (n=70) and received one of the
following premedications 30 minutes before IANB injection:
dexamethasone, pharmapain (containing acetaminophen, ibuprofen, and
caffeine), and a placebo lactose capsule. Pain severity was evaluated
with the Heft–Parker visual analog scale (VAS) before and 15 minutes
after the injection, during dentin removal, and when inserting files
into the root canal. The IANB injection was considered successful if VAS
values after 15 minutes implied no pain or mild pain.<br /><strong>Results:</strong>
IANB success rates were comparable in the dexamethasone (51.4%),
pharmapain (55.7%), and placebo (41.4%) groups (P=0.222). Pain severity
at baseline, 15 minutes post-injection, and during dentin removal was
comparable among the groups (P>0.05). However, when inserting
endodontic files, the mean pain severity in the pharmapain group was
significantly higher than the dexamethasone group (10.27 ± 1.71 versus
7.38 ± 2.24; P=0.002). No significant difference was observed between
the placebo with any of the study groups (P>0.05).<br /><strong>Conclusions</strong>:
Premedication with pharmapain (an anti-inflammatory agent) and
dexamethasone (a corticosteroid) does not enhance the success rate of
the IANB technique in mandibular molars with irreversible pulpitis

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.com0
