Traumatic dental injuries in high school athletes in the United States of America from 2005 to 2020.

BACKGROUND/AIM: Participation in sports activities is a source of dental injury. Despite recommendations for the use of mouthguards, athletes underutilize them. The aim of this study was to provide estimates of dental injuries, the mechanism of injuries and the utilization of mouthguards in high school sports. MATERIALS AND METHODS: This study was a secondary analysis of an existing dataset of a convenience sample of the National High School Sports-Related Injury Surveillance Study. Data of athletic exposures, dental injuries, mouthguard usage, and mechanism of injury from the 2005/2006 to the 2019/2020 academic years were analyzed. RESULTS: During the study period, there were 459 dental injuries in 49,987,927 athletic exposures resulting in a dental injury rate of 0.9 per 100,000 athletic exposures (AE). Slightly more than half of the traumatic dental injuries were sustained during competition (n = 256; 55.8%) and the rest (n = 200; 43.6%) were sustained during practice. The rate of dental injury in competition was 3.6 times higher than the rate in practice (RR: 3.6, 95% CI: 3.0-4.4). Dental injuries comprised 0.4% of the total 108,574 injuries sustained by athletes. Among girls' sports, field hockey had the highest rate (3.5 per 100,000 AE) and among boys' sports, basketball (2.4 per 100,000 AE) had the highest rate of dental injury. The most common mechanism of injury was contact with another player (276; 60.4%) followed by contact with apparatus (146; 31.9%). In the majority of dental injuries (308; 75.1%), the athlete was not wearing a mouthguard when the dental injury was sustained. CONCLUSIONS: Dental injuries were a small proportion of all injuries sustained by high school athletes. The majority of dental injuries were sustained when the athlete was not wearing a mouthguard.

Acceptability of medical immobilization: Results from a pilot international survey.

BACKGROUND: Controversy exists on the acceptability of medical immobilization (MI). AIM: To identify regulations, professional conventions, and opinions on the acceptability of MI and to identify practice patterns through a pilot study of members of the International Association of Paediatric Dentistry (IAPD) and their colleagues. DESIGN: A 22-item questionnaire was developed and electronically distributed to 1191 members of the IAPD. RESULTS: Responses were received from 182 dentists in 45 countries. The majority (74.9%) of respondents use MI, and 29.1% use an immobilization device. MI with an immobilization device was reported as professionally acceptable (58.1%) and permitted by medicolegal regulations (70.8%) in their countries of practice. Dentists rated acceptability of MI higher than they perceived parents would overall and perceived MI to be more acceptable by parents for emergency situations and for children with special healthcare needs but 19.8% of respondents found it totally unacceptable in all scenarios. Use and opinions of acceptability varied by geographical location with respondents from North America being more accepting of MI. Most dentists felt that the use of an immobilization device could lead to lasting psychological trauma (72.3%) and violation of the rights of the child (55.4%) but that it improves access to care (58.5%). CONCLUSION: The acceptability of MI remains an area of controversy for paediatric dentists internationally.

Absorbable Hemostatic Pack Effect After Primary Incisor Extraction: A Pilot Study and Introduction of a Novel Scale to Assess Post-Operative Bleeding.

OBJECTIVES: This pilot study compared hemostatic pack (HP) application with no intervention following extraction of maxillary primary incisors in healthy children for effect on bleeding time and influence of patient or tooth variables utilizing a novel scale for assessment of bleeding following extraction. STUDY DESIGN: A novel scale was created to assess bleeding after extraction. This scale was utilized in a randomized, split mouth study of healthy children ages 2-7 years old requiring extraction of at least 2 primary maxillary incisors under general anesthesia. One extraction site was randomly assigned to receive HP and the other had no hemostatic measures. Post-operative bleeding was rated at 2, 10, and 15 minutes post-extraction. Other variables recorded included age, sex, periapical radiolucency, presence of fistula, swelling, discoloration, intraoral stabilization device used, and vital signs at two time intervals. Pre-operative radiographs were reviewed for root resorption and periapical radiolucency. RESULTS AND CONCLUSIONS: Twenty-five patients provided 50 teeth. Hemostatic pack had a significant effect on reducing bleeding at each time point and that effect did not change over time. Age, sex, tooth pain, post-extraction heart rate, blood pressure, discoloration, amount of resorption, and presence of a periapical radiolucency had no significant effect on bleeding. The proposed bleeding scale had good intra-rater reliability and could be useful in future studies, once validated.

Gender Differences in Pediatric Dentistry Chairs in the United States and Canada.

OBJECTIVE: To analyze gender differences in personal and professional demographics, job perceptions and work satisfaction between male and female pediatric dentistry academic leaders in the United States and Canada. STUDY DESIGN: A 40-question survey was sent electronically to department chairs requesting information about demographics, current circumstances of the position, professional history, and opinions about the position. Data was analyzed by the sex of the respondent. RESULTS: Eighty-eight surveys were distributed electronically and 55 chairs responded (response rate: 62.5%). Women comprised 29.5% of the sample, were younger and had less leadership training than men. Men had served longer in the position (t(41)=2.02, p=0.05) and had higher ranking academic titles. Women spent more time managing personnel (p=0.026), creating courses and programs (p=0.029), and teaching (p=0.006) than men. Female chairs perceived to have a difficult relationship with the faculty (p=0.027), felt they received less faculty support (p=0.002), and were significantly more dissatisfied in the job (p=0.037). Men were more stressed about a heavy workload than women (p=0.001). CONCLUSION: Gender was significantly related to the demographics, experience, perceptions of the skills and abilities required for job performance, time management and job satisfaction for pediatric dentistry department chairs in American and Canadian institutions.

Analysis of Fluoride Content in Alternative Milk Beverages.

Background: The dentist has a responsibility to provide nutritional counseling and fluoride consumption recommendations. The purpose of this study was to measure and compare the concentrations of fluoride in a large number of alternative milk beverages and bovine milk. Study design: Thirty-three milk alternatives, including 9 diverse types and 11 different brands, were analyzed using a fluoride ion-selective electrode (ISE) and an ISE meter. Fluoride concentrations were then compared among different types and between different brands. Results: Fluoride concentration ranged from 0.01 ppm (Malk® Pure Cashew Milk) to 0.80 ppm (Almond Breeze® Original Unsweetened Almond Milk) with a mean concentration of 0.32 ppm. When compared, bovine whole milk (0.03±0.00 ppm) was found to be significantly lower in fluoride than all samples analyzed except Malk Pure Cashew Milk, Soy Milk Vanilla, Rice Milk, and Pecan Milk. Major differences also existed between the same milk alternative types of different brands. Conclusion: The amount of fluoride varies among different types of milk alternatives and different brands. To ensure that the dental team can provide proper recommendations regarding fluoride use, manufacturers should consider placing fluoride concentrations on nutrition labels.

Effect of Light Cure Methods for Intermediate Adhesive Layer on Microleakage of Sealants. An in Vitro Study.

Background: The objective of this study was to determine the effect of an adhesive layer and its photopolymerization on the microleakage of sealants. Study design: 0.5mm-deep standardized fissurectomies were performed on extracted molars (n = 72). Teeth were randomly assigned to 3 different sealant materials (n = 24/group). Teeth were further divided to receive sealants with or without an adhesive layer. Each sealant with adhesive was also divided into two groups: adhesive was light-cured separately or light cured together with the sealant. Following thermocycling, microleakage was assessed using dye penetration and image analysis. Data was analyzed using ANOVA and Tukey's studentized ranged HSD tests. Results: Microleakage was not affected by type of sealant material (p>0.05) but was significantly influenced by application (p<0.05). Overall, placement of sealants without adhesive displayed greater microleakage than sealants with uncured adhesive (p<0.05). Within individual sealant types, this difference was only significant for Ultraseal XT (p<0.05). Sealants bonded with and without prior light curing did not show a significant difference in levels of leakage (Tukey's Studentized Range Test, p>0.05). Conclusion: An adhesive layer should be placed beneath sealants, but whether it should be light cured or left uncured before sealant placement varies by the sealant type.

Analysis of the Cariogenic Potential of Various Almond Milk Beverages using a Streptococcus mutans Biofilm Model in vitro.

To evaluate the cariogenic properties of almond milk beverages, 6 almond milks, along with soy and whole bovine milk, were analyzed for their abilities to support Streptococcus mutans biofilm formation and acid production, and their capacity to buffer changes in pH. Biofilm formation by S. mutans was analyzed using an in vitro 96-well plate model and measured by crystal violet staining. Acid production by S. mutans was evaluated by a colorimetric L-lactate assay and pH measurement of bacterial cultures. Buffering capacity was assessed by a pH titration assay. Soy milk supported the most biofilm growth, while the least was observed with unsweetened almond milk (both p < 0.001). Among almond milks, sucrose-sweetened milk led to the highest level of biofilm formation (p < 0.001), while the least was observed with unsweetened milk (p < 0.05). Sucrose-sweetened almond milk yielded the lowest pH (4.56 ± 0.66), followed by soy milk and bovine milk; the highest pH was with unsweetened almond milk (6.48 ± 0.5). When analyzed by pH titration, the unsweetened almond milk displayed the weakest buffering capacity while bovine milk showed the highest (p < 0.001). These results suggest that the almond milk beverages, except those that are sweetened with sucrose, possess limited cariogenic properties, while soy milk exhibits the most cariogenic potential. As milk alternatives become increasingly popular, dentists must counsel their patients that almond milks, especially sucrose-sweetened varieties, have cariogenic potential. For patients who are lactose-intolerant or suffer from milk allergy, almond milks may be a better alternative than soy-based products.

Behavior guidance: that was then but this is now.

Pediatric dentistry has evolved. Seasoned pediatric dentists believe that patients, parents, and behavior techniques have changed over their practice lifetimes. The purpose of this article is to provide dentists with a framework in which to adapt to the changes in society. Understanding cultural diversity, current societal values, technology and media influences, and contemporary parenting philosophies is essential to fostering communication with patients and their families. Building and honing behavior guidance skills are part of the process by which dentists help turn child patients into fearless adult patients with excellent oral health. This article reviews basic techniques and offers practical examples of implementing these in daily practice. The discussion also addresses changing parental and societal acceptance of various techniques and dentists' responsibility for informed consent regarding the risks and benefits of advanced behavior guidance techniques. Treating a patient from childhood to adulthood is the ultimate opportunity for the dentist to play a vital role in advancing the health and wellness of another human being.

Dental Age Difference in Children with ADHD.

OBJECTIVE: The purpose of this study was to determine if changes in dental development are associated with Attention Deficit Hyperactivity Disorder (ADHD) or ADHD medications. STUDY DESIGN: This retrospective chart review evaluated the dental age of 128 patients between 6 and 16 years of age using the Demirjian method from the following two groups a) children with ADHD b) unaffected children. The ADHD group was further stratified into four groups according to the medication type. The impact of ADHD on dental age difference (the difference between dental age and chronologic age) was analyzed using T-test and the association between medication type and dental age difference was analyzed through one way ANOVA. RESULTS: The mean difference between estimated dental age and chronologic age (dental age difference) for all subjects was 0.80 years. There was no significant dental age difference in subjects with ADHD and the control group (0.78±1.28vs. 0.84 ±1.09 years respectively; P=0.75) and there was no significant difference in dental age difference and type of medication (P=0.84). CONCLUSION: No significant difference was found between children with ADHD and unaffected children with respect to dental age difference. No significant differences were found in dental age difference in the four medication groups.

Use of local anesthesia during dental rehabilitation with general anesthesia: a survey of dentist anesthesiologists.

The purpose of this study was to document current practices of dentist anesthesiologists who are members of the American Society of Dentist Anesthesiologists regarding the supplemental use of local anesthesia for children undergoing dental rehabilitation under general anesthesia. A survey was administered via e-mail to the membership of the American Society of Dentist Anesthesiologists to document the use of local anesthetic during dental rehabilitations under general anesthesia and the rationale for its use. Seventy-seven (42.1%) of the 183 members responded to this survey. The majority of dentist anesthesiologists prefer use of local anesthetic during general anesthesia for dental rehabilitation almost always or sometimes (90%, 63/70) and 40% (28/70) prefer its use with rare exception. For dentist anesthesiologists who prefer the administration of local anesthesia almost always, they listed the following factors as very important: "stabilization of vital signs/decreased depth of general anesthesia" (92.9%, 26/28) and "improved patient recovery" (82.1%, 23/28). There was a significant association between the type of practice and who determines whether or not local anesthesia is administered during cases. The majority of respondents favor the use of local anesthesia during dental rehabilitation under general anesthesia.

Sugar substitutes on caries prevention in permanent teeth among children and adolescents: a systematic review and meta-analysis.

OBJECTIVES: This study aimed to systematically review the effect of sugar substitute consumption on caries prevention in permanent teeth among children and adolescents. DATA: Randomized controlled trials (RCTs) and controlled clinical trials (CCTs) comparing the clinical effect of sugar substitutes (both high- and low-intensity sweeteners) in preventing caries in permanent teeth among children and adolescents aged 6-19 were included. SOURCES: A systematic search was conducted in three databases (PubMed, Web of Science and Embase) without any restrictions on publication year. STUDY SELECTION: The initial search found 1,859 items, and finally, 15 studies (11 RCTs and 4 CCTs) with a total of 6325 participants (age: 6-18 years) were included. The Cochrane risk-of-bias assessment tools were used for quality assessment. Most (80%, 12/15) were graded as having a 'moderate' or 'high' risk of bias. All trials investigated sugar alcohol, which is a low-intensity sweetener. Xylitol was the most commonly investigated (73.3%, 11/15), followed by sorbitol (46.7%, 7/15), and erythritol (13.3%, 2/15). Results of the meta-analysis showed that both xylitol (standardized mean difference [SMD]: -0.50, 95% confidence interval [CI] -0.85 to -0.16, P = 0.005) and sorbitol (SMD: -0.10, 95% CI: -0.19 to -0.01, P = 0.03) had a significant effect in preventing dental caries compared to no treatment/placebo. No clinical trials on high-intensity sweeteners such as aspartame and saccharin were found. CONCLUSION: The consumption of xylitol or sorbitol is potentially effective in preventing caries in permanent teeth among children and adolescents. No clinical evidence is available regarding the role of high-intensity sweeteners in caries prevention. CLINICAL SIGNIFICANCE: The use of xylitol or sorbitol as sugar substitutes has a beneficial effect in preventing dental caries among children and adolescents.

Evaluation of 3 commercially available materials for resolution of white spot lesions.

INTRODUCTION: White spot lesions are often seen on the teeth after orthodontic treatment, resulting in unpleasant esthetics. The aim of this in-vitro study was to compare subjectively and objectively the esthetic outcomes of white spot lesions treated with 3 commercially available products that have been reported to have a positive effect on the remineralization of enamel. METHODS: Forty extracted premolars were randomly allocated into 1 of 4 groups (n = 10). The teeth were exposed to a demineralization solution at 37°C for 14 days to produce white spot lesions that were about 100 µm deep. Each group was then randomly assigned to receive either control treatment with artificial saliva or treatment with 1 of the 3 commercially available products: Restore toothpaste (Dr. Collins Inc, Orange County, Calif), which contains NovaMin (Dr. Collins Inc); Prevident 5000 (Colgate, New York, NY); and MI Paste Plus (GC America, Alsip, Ill). All groups were evaluated 5 times at 6 time points during the study. RESULTS: The subjective and objective results were mixed within groups and between groups for the products tested. CONCLUSIONS: We found no conclusive evidence that any of these 3 materials produced more favorable esthetic white spot lesion remineralization results.

Prevalence and variations of the median maxillary labial frenum in children, adolescents, and adults in a diverse population.

The median maxillary labial frenum (MMLF) is a normal anatomic structure with inherent morphologic variations. This study sought to evaluate the prevalence of those variations in a diverse ethnic population and to educate practitioners about the prevalence of MMLF variations to prevent unnecessary biopsies. This study included adult, adolescent, and child patients at the Louisiana State University Health Science Center School of Dentistry. Among the 284 subjects examined, frenum normale was the most common frenum classification, followed by frenum with nodule and frenum with appendix. Most nodules were found in the intermediate third of the MMLF, while appendices were mainly found in the labial third. The prevalence of an appendix was significantly higher (P < 0.001) in Caucasians compared to African-Americans. The prevalence of nodules was marginally higher (P = 0.096) in Caucasians than in African-Americans. No other statistically significant differences were found with regard to ethnicity. Additionally, nodules and appendices on the MMLF were identified in all age groups, and may become more common with increasing age. The authors determined that variations of the MMLF are inherent and do not represent a pathologic condition, nor do they require biopsy for diagnostic purposes.

Assessing Pediatric Dental Resident Sedation Skills and Confidence with Simulation: A Pilot Study.

Purpose: To conduct a pilot study assessing resident performance and self-efficacy during sedation-related simulations. Methods: Residents completed one informed consent and two sedation-related emergency simulations. Performance was measured for each simulation. Self- efficacy (i. e., confidence) was measured via pre- and post-simulation questionnaires. Descriptive and nonparametric statistics were calculated. Results: Twenty-five residents completed the simulations. Second-year residents performed better than first-year residents in both informed consent and emergency simulations; however, only the informed consent simulation was significant (P<0.02). Self-efficacy significantly increased after completing the simulations (18 percent pre-simulation versus 42.7 percent post-simulation, P<0.001). Residents identified communication skills as an area of improvement after the simulations. For the emergency vignettes, residents expressed feeling inadequate knowledge, problem-solving skills, and teamwork during the simulation. Conclusions: Simulations improved resident confidence in obtaining informed consent and managing certain sedation-related emergencies, but residents felt ill-prepared to manage an emergency. Further study is warranted to understand the best-practice frequency of sedation-related emergency simulation to promote skill retention.

Kovanaze Intranasal Spray vs Traditional Injected Anesthetics: a Study of Pulpal Blood Flow Utilizing Laser Doppler Flowmetry.

OBJECTIVE: An ideal local anesthetic would be effective, minimally reduce pulpal blood flow (PBF), and not require injection. This study compared the effects of 3% tetracaine plus 0.05% oxymetazoline nasal spray (Kovanaze; KNS) and injections using 2% lidocaine with 1:100,000 epinephrine (LE) or 3% mepivacaine plain (MP) on PBF, anesthetic efficacy, and participant preference. METHODS: In a double-blind cross-over design, 20 subjects randomly received a test anesthetic and placebo at each of 3 visits (KNS/mock infiltration; mock nasal spray/LE; or mock nasal spray/MP). Nasal sprays and infiltration apical to a maxillary central incisor were delivered ipsilaterally. PBF was evaluated by laser Doppler flowmetry, and local anesthetic success was assessed with electric pulp testing. Postoperative pain levels, participant preference, and adverse events were also assessed. RESULTS: LE injections demonstrated significant reductions in PBF at all time intervals compared with baseline (P < .05), whereas KNS and MP did not. Pulpal anesthesia success rates were higher for LE (85%) compared with MP (35%) and KNS (5%). Participants reported significantly higher postoperative pain levels for KNS compared with LE and MP. Additionally, KNS was the least preferred of the anesthetics administered and resulted in more reported adverse events. CONCLUSION: Although KNS showed no significant effect on PBF, it was not effective in achieving pulpal anesthesia as used in this study.

Adolescent Dental Fear and Anxiety: Background, Assessment, and Nonpharmacologic Behavior Guidance.

Adolescence, the period from 11 to 21 years of age, bridges the chasm between childhood and adulthood. Adolescence can be challenging as bodies, cognition, and personality go through major transformations, but it is also a time of great joy as confident adults with a clear identity develop. Dentists need to be knowledgeable about the developmental characteristics of this group because some of the cognitive and emotional changes make adolescents vulnerable to new fears. Dentists must tailor behavior guidance to this developing psyche in a way that respects independence and promotes confidence to foster lifelong positive views of dentistry.

Is methylmethacrylate toxic during pregnancy and breastfeeding?--- a systematic review.

INTRODUCTION: Methyl methacrylate (MMA) is commonly used in the fields of dentistry and orthopaedic surgery. However, there remain concerns for the occupational hazards of MMA, particularly during pregnancy and breastfeeding. METHODS: We performed a systematic review of studies on effects that MMA may have in pregnancy in the context of exposure during orthopaedic surgery and dentistry. Review articles, studies lacking statistical data, single case reports and other evidence level V studies were excluded. RESULTS: Nine studies were included. One basic science study demonstrated an increase in neuronal cell lysis and shrunken cell bodies when neocortical neurons were exposed to MMA monomer. Three animal studies exposed pregnant rodents to MMA via intraperitoneal injection or inhalation. Exposed fetuses in two studies had an increase in gross abnormalities such as hemangiomas, while there was no increase in teratologic effects in the third study. In dental workers exposed to MMA, two retrospective cohort studies did not find a statistically significant increase in birth defects or miscarriage. After exposure to MMA during total joint arthroplasty, two studies found that MMA levels were undetectable in the mothers' serum or breast milk. One study measuring the airborne levels of MMA during simulated joint arthroplasty found that concentrations never exceeded 1% of the recommended limit set forth by the Occupational Safety and Health Administration (OSHA). CONCLUSIONS: Potential teratologic effects of MMA cannot be excluded by existing evidence. However, the typical MMA exposure levels for dental and orthopaedic personnel appear to be substantially less than currently proposed exposure limits.

Connecting Medical Personnel to Dentists via Teledentistry in a Children's Hospital System: A Pilot Study.

Investigators evaluated feasibility, acceptability, and sustainability of a teledentistry pilot program within a children's hospital network between March, 2018, and April, 2019. The program connected dentists to medical personnel and patients being treated in urgent care clinics, a primary care clinic, and a freestanding emergency department via synchronous video consultation. Three separate but parallel questionnaires evaluated caregiver, medical personnel, and dentist perspectives on the experience. Utilization of teledentistry was very low (2%, 14/826 opportunities), but attitudes regarding this service were largely positive among all groups involved and across all survey domains. Uptake of new technology has barriers but teledentistry may be an acceptable service, especially in the case of dental trauma.

Ohio Dentists' Perceptions on Children School Absenteeism for Dental Care Appointments.

Purpose: This cross-sectional study evaluated knowledge, practices, and beliefs of Ohio dentists treating school-aged children regarding school absenteeism in relation to compliance with dental appointments.
Methods: A 26-item questionnaire was distributed to 7,274 dentists licensed in the state of Ohio in 2019. Eligible participants were pediatric dentists (PDs) and general dentists (GDs) who treated individuals younger than 16 years of age.
Results: A return rate of 13.5 percent (958 total participants) provided a sample consisting of approximately 90 percent of GDs, a mean age of 48.5 years and primarily practicing in suburban locations. Respondents felt parental attitudes had changed over the past five years, with a significantly higher proportion of PDs reporting increased parental concerns about school absences than GDs (59.5 percent versus 31.5 percent; P <0.001). Length of excused absence increased with treatment complexity. PDs were more likely to permit longer absences than GDs and to allow parents to decide the length of absence, particularly for children with special health care needs. PDs were 6.6 times more likely to report that concerns about school absences often negatively affected oral health (P <0.001).
Conclusion: Dentists acknowledged that school absences and school policy affected parental choices regarding dental visits, with PDs consistently stating a greater effect than GDs.

Correlates of oral health fatalism in caregivers of children with autism spectrum disorder.

AIMS: To study correlates of oral health fatalism (OHF) in caregivers of children with autism spectrum disorder (ASD). METHODS AND RESULTS: This exploratory analysis used baseline data from 118 Medicaid-eligible families of children with ASD in a multi-site randomized clinical trial of a parent training intervention supporting home oral hygiene and dental visits. About half (46%) of caregivers agreed with the statement "most children eventually develop dental cavities," endorsing OHF. Hispanic caregivers more strongly endorsed OHF than non-Hispanics (cumulative odds ratio = 2.4, 95% confidence interval [CI]: 1.2-4.7, P = .014). Caregivers living alone with children less strongly endorsed OHF than caregivers cohabitating with other adults (cumulative odds ratio = 0.39, 95% CI 0.17-0.86, P = .019). Multivariable analysis maintained significance of ethnicity (P = .030) but not living situation (P = .052). Additional analyses included demographics, parenting beliefs, and children's oral hygiene and oral health status. CONCLUSION: About half the caregivers endorsed OHF, with Hispanic caregivers more strongly endorsing OHF. OHF was not significantly associated with oral health behaviors or status, consistent with emerging literature suggesting fatalism is not necessarily linked to health behavior. Further exploration of OHF correlates in families of children with ASD is needed; ethnicity, living situation, child age, and caries status are of interest.
