Recreational divers should consider consulting with their dentist before diving if they recently received dental care, says Vinisha Ranna, BDS, lead author and a student in the UB School of Dental Medicine.
"Divers are required to meet a standard of medical fitness before certification, but there are no dental health prerequisites," says Ranna, who is also a certified stress and rescue scuba diver.
"Considering the air supply regulator is held in the mouth, any disorder in the oral cavity can potentially increase the diver's risk of injury. A dentist can look and see if diving is affecting a patient's oral health."
The study, "Prevalence of dental problems in recreational SCUBA divers," was published last month in the British Dental Journal.
The research was inspired by Ranna's first experience with scuba diving in 2013. Although she enjoyed being in the water, she couldn't help but notice a squeezing sensation in her teeth, a condition known as barodontalgia.
Published research on dental symptoms experienced while scuba diving is scarce or focuses largely on military divers, says Ranna, so she crafted her own study. She created an online survey that was distributed to 100 certified recreational divers. Those who were under 18-years-old, ill or taking decongestant medication were excluded.
Her goal was to identify the dental symptoms that divers experience and detect trends in how or when they occur.
Of the 41 participants who reported dental symptoms, 42 percent experienced barodontalgia, 24 percent described pain from holding the air regulator in their mouths too tightly and 22 percent reported jaw pain.
Another five percent noted that their crowns were loosened during their dive, and one person reported a broken dental filling.
"The potential for damage is high during scuba diving," says Ranna, who has completed 60 dives.
"The dry air and awkward position of the jaw while clenching down on the regulator is an interesting mix. An unhealthy tooth underwater would be much more obvious than on the surface. One hundred feet underwater is the last place you want to be with a fractured tooth."
The study also found that pain was most commonly reported in the molars and that dive instructors, who require the highest level of certification, experienced dental symptoms most frequently. This frequency is likely attributed to more time spent at shallower depths where the pressure fluctuations are the greatest, says Ranna.
The Professional Association of Diving Instructors has issued more than 24 million certifications around the world. As scuba diving gains popularity as a recreational sport, Ranna hopes to see oral health incorporated into the overall health assessments for certification.
Patients should ensure that dental decay and restorations are addressed before a dive, and mouthpiece design should be evaluated by manufacturers to prevent jaw discomfort, particularly when investigating symptoms of temporomandibular joint disorder in divers, says Ranna.
Additional investigators on the study include Hans Malmstrom, DDS, professor; Sangeeta Gajendra, DDS, associate professor; Changyong Feng, PhD, associate professor; and Michael Yunker, DDS, assistant professor, all of the University of Rochester School of Medicine and Dentistry.
Ranna is conducting a follow-up study with an expanded group of more than 1,000 participants.

ST. PAUL, Minn. – (Dec. 20, 2016) – In too many places around the world, people are suffering immensely from poor oral health. Despite its critical role in overall health, oral care is often overlooked, resulting in a population that suffers. Children who aren’t given proper access to care often have caries and struggle in school because they are in so much pain. These children grow up to become adults and elderly patients who aren’t nearly as educated or healthy as they could be. As a step to ignite worldwide change for oral health, 3M welcomed professionals and policy makers from around the world to the first-ever Oral Health Council on Nov. 28-30, 2016 at the 3M Innovation Center.
The meeting served as a forum for industry leaders from Chile, China, Bolivia, Colombia, the United Kingdom, Peru, Russia and the United States to share the challenges their countries face in delivering care to patients. Attendees learned from industry experts about preventive science innovations, how to better care for elderly, special needs and pediatric patients, and how to implement effective policy for oral health. Attendees walked away from the meeting with solid action plans to improve oral health in their communities.
“Governments are instrumental in influencing the standard for healthcare, so people with a voice must advocate for change – even if it starts small at first” said Simon Hearne, International Vice President for 3M Oral Care. “As a global industry leader, 3M is taking the responsibility to help people who can inspire change create a network that will aid them in promoting preventive oral care within their communities.”
3M plans to continue this global initiative, and looks forward to the impact this council will have on the future of worldwide oral health.

Can nocturnal use of implant-retained overdenture improve cardiorespiratory stability of a patient with obstructive sleep apnea? A clinical report
AbstractFew studies have evaluated the interaction between conventional complete dentures (CCD) and the respiratory system and the authors are unaware of any that evaluated the interaction between implant-retained overdentures (IROs) and the respiratory system. This clinical report documented the effects of wearing an IRO on the cardiorespiratory stability of an edentulous patient with obstructive sleep apnea (OSA). A 64-year-old woman was referred to the department of otolaryngology because of daytime sleepiness and morning headaches. The patient refused polysomnographic evaluation because of claustrophobia. Overnight pulse oximetry (PO) was performed to detect cardiorespiratory stability during sleep, and the oxygen desaturation index (ODI) of the patient was found to be 20.9. A mandibular advancement device (MAD) was fabricated; however, the patient did not comply with the treatment and stopped using the MAD because of intraoral discomfort. Therefore, the patient started to wear the conventional complete dentures (CCDs) nocturnally to prevent upper airway collapses. Despite the significant drop in ODI score to 12.6, because of displacement, the mandibular denture was converted to an IRO. The PO tests performed after another 6 months revealed an ODI score of 7.8. Wearing CCDs might improve respiratory stability of patients with edentulism during sleep; however, more favorable results could be obtained with IROs.

Effectiveness of DIAGNOdent in Detecting Root Caries Without Dental Scaling Among Community-dwelling Elderly
Page 555-561, doi:10.3290/j.ohpd.a37140
Materials and Methods: The status of 750 exposed, unfilled root surfaces was assessed by visual-tactile examination and DIAGNOdent before and after root scaling. The sensitivity and specificity of different cut-off DIAGNOdent values in diagnosing root caries with reference to visual-tactile criteria were evaluated on those root surfaces without visible plaque/calculus. The DIAGNOdent values from sound and carious root surfaces were compared using the nonparametric Mann-Whitney U-test. The level of statistical significance was set at 0.05.
Results: On root surfaces without plaque/calculus, significantly different (p < 0.05) DIAGNOdent readings were obtained from sound root surfaces (12.2 ± 11.1), active carious root surfaces (37.6 ± 31.7) and inactive carious root surfaces (20.9 ± 10.5) before scaling. On root surfaces with visible plaque, DIAGNOdent readings obtained from active carious root surfaces (29.6 ± 20.8) and inactive carious root surfaces (27.0 ± 7.2) were not statistically significantly different (p > 0.05). Furthermore, on root surfaces with visible calculus, all DIAGNOdent readings obtained from sound root surfaces were > 50, which might be misinterpreted as carious. After scaling, the DIAGNOdent readings obtained from sound root surfaces (8.1 ± 11.3), active carious root surfaces (37.9 ± 31.9) and inactive carious root surfaces (24.9 ± 11.5) presented significant differences (p < 0.05). A cut-off value between 10 and 15 yielded the highest combined sensitivity and specificity in detecting root caries on root surfaces without visible plaque/calculus before scaling, but the combined sensitivity and specificity are both around 70%.
Conclusion: These findings suggest that on exposed, unfilled root surfaces without visible plaque/calculus, DIAGNOdent can be used as an adjunct to the visual-tactile criteria in detecting root-surface status without pre-treatment by dental scaling.

Purpose: To compare the effect of toothbrushing abrasion with hydrated silica-based whitening and regular toothpastes on root dentin using contact profilometry.
Materials and Methods: Ninety dentin specimens (4 x 4 x 2 mm) were randomly divided into five experimental groups (n = 18) according to the toothpaste: three whitening (W1, W2 and W3) and two regular toothpastes (R1 and R2) produced by two different manufacturers. Using a brushing machine, each specimen was brushed with a constant load of 300 g for 2500 cycles (4.5 cycles/s). The toothpastes were diluted at a ratio of 1:3 w/w (dentifrice:distilled water). The brush diamond tip of the profilometer moved at a constant speed of 0.05 mm/s with a force of 0.7 mN.
Results: The average value of brushing abrasion in μm (mean ± SD) was obtained from five consecutive measurements of each specimen: W1 = 8.86 ± 1.58, W2 = 7.59 ± 1.04, W3 = 8.27 ± 2.39, R1 = 2.89 ± 1.05 and R2= 2.94 ± 1.29. There was a significant difference between groups (ANOVA, p<0 .0001="" all="" among="" and="" between="" but="" comparisons="" differences="" for="" multiple="" nbsp="" nor="" not="" p="" post-hoc="" regular="" s="" showed="" test="" the="" toothpastes.="" toothpastes="" tukey="" whitening="">
Conclusion: The whitening toothpastes tested can cause more dentin abrasion than the regular ones.0>

Relationship Between Oral Health Knowledge, Attitude and Practices of Primary School Teachers and Their Oral Health-related Quality of Life: A Cross-sectional Study
Page 519-528, doi:10.3290/j.ohpd.a37137
Purpose: To measure oral health (OH) knowledge, attitude and practices (KAP) of primary school teachers and to evaluate the relationship between these measures and oral health-related quality of life (OHRQoL).
Materials and Methods: A total of 1013 school teachers from all regions of Kuwait were randomly selected in this cross-sectional study. A questionnaire on demographics, knowledge, attitude, practices and OHRQoL was used. Frequencies and means (SD) were used for data description.
Correlations between KAP and OHRQoL were evaluated using Pearson's correlation coefficient. Associations between practice-specific knowledge and its corresponding practice as well as knowledge and practices and OHRQoL were determined using the chi-squared test.
Results: About 71% of the participants were females, 57% were 30-50 years old, and 75% had a college education. The mean (95%CI) knowledge score was 60.2% (57.2-62.0), ranging from 15.4% to 93%. The well-known OH facts were the importance of brushing twice a day with fluoridated toothpaste, the cariogenic effect of sticky, sugary foods and snacks, as well as the damage that soft drinks can cause to teeth. The least known facts were replacement frequency of toothbrush, parent's supervision of children's brushing and the benefit of regular flossing. Weak but significant correlations were found between KAP components and OHRQoL (p < 0.05). All practice-specific OH knowledge was significantly associated with its practice, except brushing and flossing (p > 0.05). Self-esteem was the mostly frequently affected OHRQoL construct by improper OH practices.
Conclusion: Oral health knowledge by itself is not enough to change improper OH practices. Developing behaviourchanging interventions based on OHRQoL outcomes may be beneficial.

Purpose: Little is known about use or acceptance of minimally invasive dentistry (MID) in the USA, particularly in public health settings. The purpose of this study was to assess opinions concerning MID among dentists in public-health practices.
Materials and Methods: A cross-sectional study was conducted to assess the views of dentists in public-health practices concerning MID using an online survey instrument among National Network for Oral Health Access (NNOHA) and American Association of Community Dental Programs (AACDP) members. Specific questions focused on diagnostic and preventive techniques, and whether MID was considered to meet the standard of care in the US.
Results: Overall, 86% believed that MID met the standard of care for primary teeth, and 77% did so for permanent teeth. The majority of respondents also agreed that fluoride varnish prevents caries and atraumatic restorative techniques (ART) are an effective caries treatment for children and adults. According to logistic regression results, dentists who had continuing education courses in MID and agreed that ART was an effective treatment for adults were more likely to report that MID met the standard of care for permanent teeth. Subjects who believed that fluoride varnish was effective as caries prevention for children were more likely to view MID as meeting the standard of care for primary teeth.
Conclusions: There appears to be a paradigm shift toward a MID philosophy, and most responding public health dentists believed that MID meets the standard of care for primary and permanent teeth in the US.

Randomised Clinical Trial on Resin Infiltration and Fluoride Varnish vs Fluoride Varnish Treatment Only of Smooth-surface Early Caries Lesions in Deciduous Teeth
Page 485-491, doi:10.3290/j.ohpd.a37135
Purpose: To clinically evaluate the effectiveness of resin infiltration in conjunction with fluoride varnish treatment vs fluoride varnish treatment alone on facial smooth-surface caries lesions in deciduous teeth.
Materials and Methods: This randomised clinical trial was conducted in 419 children aged 18-71 months with at least two active smooth-surface caries lesions in deciduous teeth (ICDAS II score 2). Eighty-one participants met the inclusion criteria and were allocated to one of the two treatment groups: resin infiltration and fluoride varnish (RI+FV) (n = 41) and fluoride varnish only (FV) (n = 40). The prevalence of treated white spot lesions (WSL) was scored. Fluoride varnish was applied in both groups every 3 months for a year.
Results: The mean baseline age of children was 3.8 ± 1.3 years. The effectiveness of resin infiltration measured as the percentage of children who did not present any progression of the treated lesions amounted to 43.1%. After one year, 92.1% of the infiltrated lesions (RI+FV) and 70.6% of the FV lesions had not progressed (p < 0.001).
Conclusion: Resin infiltration in conjunction with fluoride varnish treatment of early facial smooth-surface caries lesions in deciduous teeth is superior to fluoride varnish treatment alone for reducing lesion progression.
The ADA News (12/15, Garvin) reports the EPA released a final rule requiring that all dental practices nationwide install amalgam separators, stating in the final rule executive summary, “EPA has concluded that requiring dental offices to remove mercury through relatively low-cost and readily available amalgam separators and BMPs makes sense.” The ADA commended the EPA, who listened to the association’s input and incorporated the ADA House of Delegates’ nine principles regarding a potential amalgam rule into the final product. In a statement, ADA President Dr. Gary L. Roberts said, “The ADA believes the Environmental Protection Agency’s new federal regulation represents a fair and reasonable approach to the management of dental amalgam waste.”
The ADA released a statement reaffirming its positionthat “dental amalgam is a durable, safe and effective cavity-filling option” and providing information for patients about restorative materials at MouthHealthy.org. The ADA provides more information on amalgams at ADA.org/RecycleAmalgam.

- First published:
- Full publication history
- DOI: 10.1111/iej.12719
AimThe aim of this multicentre, parallel-group randomized clinical trial was to compare the effectiveness of mineral trioxide aggregate (MTA) and a conventional calcium hydroxide liner (CH) as direct pulp capping materials in adult molars with carious pulpal exposure.
MethodologySeventy adults aged 18–55 years were randomly allocated to two parallel arms: MTA (White ProRoot, Dentsply, Tulsa Dental, Tulsa, OK, USA; n = 33) and CH (Dycal®, Dentsply DeTrey GmbH, Konstanz, Germany; n = 37). The teeth were temporized for 1 week with glass–ionomer (Fuji IX, GC Corp, Tokyo, Japan) and then permanently restored with a composite resin. The subjects were followed up after 1 week and at six, 12, 24 and 36 months. The primary outcome was the survival of the capped pulps, and the secondary outcome was postoperative pain after 1 week. Survival was defined as a nonsymptomatic tooth that responded to sensibility testing and did not exhibit periapical changes on radiograph. At each check-up, the pulp was tested for sensibility and a periapical radiograph was taken (excluding the radiographs taken at the 1-week follow-up). Kaplan–Meier survival analysis and log-rank test were used to assess the significant difference in the survival curves between groups. Chi-square test was used to assess the association between the materials and preoperative and postoperative pain.
ResultsAt 36 months, the Kaplan–Meier survival analysis showed a cumulative estimate rate of 85% for the MTA group and 52% for the CH group (P = 0.006). There was no significant association between the capping material and postoperative pain.
ConclusionsMineral trioxide aggregate performed more effectively than a conventional CH liner as a direct pulp capping material in molars with carious pulpal exposure in adult patients. This study has been registered at ClinicalTrials.gov, number NCT01224925.

BACKGROUND AND OVERVIEW:There is a lack of clinical research on the potential effect of cannabis use on the periodontium as well as its effect on treatment outcomes. The aim of this case report is to illustrate the clinical presentation of periodontal disease in a young woman who was a chronic cannabis user, as well as successful treatment involving motivating the patient to quit cannabis use and undergo nonsurgical and surgical therapy.
CASE DESCRIPTION:A 23-year-old woman sought care at the dental clinic for periodontal treatment. During a review of her medical history, the patient reported using cannabis frequently during a 3-year period, which coincided with the occurrence of gingival inflammation. She used cannabis in the form of cigarettes that were placed at the mandibular anterior region of her mouth for prolonged periods. Localized prominent papillary and marginal gingival enlargement of the anterior mandible were present. The mandibular anterior teeth showed localized severe chronic periodontitis. The clinicians informed the patient about the potentially detrimental consequences of continued cannabis use; she was encouraged to quit, which she did. The clinicians performed nonsurgical therapy (scaling and root planing) and osseous surgery. The treatment outcome was evaluated over 6 months; improved radiographic and clinical results were observed throughout the follow-up period.
CONCLUSIONS AND PRACTICAL IMPLICATIONS:Substantial availability and usage of cannabis, specifically among young adults, requires dentists to be vigilant about clinical indications of cannabis use and to provide appropriate treatments. Behavioral modification, nonsurgical therapy, and surgical therapy offer the potential for successful management of cannabis-related periodontitis.

Comparison of implant versus tooth-supported zirconia-based single crowns in a split-mouth design: a 4-year clinical follow-up study
Materials and methods
Vol 3, No 4 (2016)
Statement of Problem: Pit and fissure sealant therapy has been approved as an effective measure in the prevention of occlusal dental caries. Resin based ma- terials are the most common materials used worldwide. A variety of resin based fissure sealants are produced and used. Most of them have been presented with ideal results in research environment. However, their effectiveness in the real life, especially in a mass application program such as Iran’s oral health reform plan is not clear.
Objectives: To evaluate the longevity of different fissure sealant applied in Iran’s oral health reform plan in Fars Province (south of Iran) after one year.
Materials and Methods: Seven counties were selected. One hundred 6- to
8-year-old school children who had undergone fissure sealant therapy in spring
2015 were randomly selected from each county. Their first molars were exam- ined to evaluate the status of the fissure sealants which were applied one year ago. Data on the type/brand of fissure sealant materials, type and experience of clinicians who applied them, existence of a chair-side assistant, and whether the children were caries-free at the time of fissure sealant application were collected from the existing reports.
Results: Data of 1974 teeth from 598 children were used for the final analysis. The effects of type/brand of the material was significant on the final results and remained significant (p < 0.001) after adjustments for the level of fluoride, urban/rural area, upper/lower jaw, type of clinician who applied the sealant, existence of a chair-side assistant, and child’s gender, age, and being caries-free.
Conclusions: Many factors affect the success rate of a fissure sealant therapy program. The type/brand of the material remained significantly related to the success rate of the fissure sealant even after adjustments for other influencing factors. In this study, ClinproTM Sealant (3M/ESPE, USA) showed better longevity after one year of application.
