Item Dental maturity of Caucasian children in the Indianapolis area(American Academy of Pediatric Dentistry, 2011-05) Weddell, Lauren S.; Hartsfield, James K.; Department of Pediatric Dentistry, School of DentistryPURPOSE: The purpose of this study was to compare chronologic and dental age using Demirjian's method. METHODS: Two hundred and fifty-seven panoramic radiographs of healthy 5- to 17.5-year-old Caucasian children in the Indianapolis area were evaluated using Demirjian's 7 tooth method. RESULTS: The intraclass correlation coefficient (ICC) for agreement with Demirjian was 0.94 (95% confidence interval [CI]: 0.87, 0.97). The ICC for repeatability of the investigator was 0.97 (95% CI=0.95, 0.99). Calculated dental age was significantly greater than chronologic age by 0.59 years (P<.001). There was no significant difference in the mean difference in ages between sexes (P=.73). Medicaid subjects had a significantly higher (P<.001) mean difference (0.82 years) than private insurance subjects (0.32 years). There was a significant negative correlation between the chronologic age and the difference in ages (r=-0.29, P<.001). Overweight (P<.001) and obese (P=.004) subjects were significantly more dentally advanced than normal (P=.35) and underweight (P=.42) subjects. CONCLUSIONS: Demirjian's method has high inter- and intraexaminer repeatability. Caucasian children in the Indianapolis area are more advanced dentally than the French-Canadian children studied by Demirjian. Difference between dental age and chronologic age varies depending on the age of the child, socioeconomic status, and body mass index.Item The effect of intraoral suction on oxygen-enriched surgical environments: a mechanism for reducing the risk of surgical fires(American Dental Society of Anethesiology, 2014) VanCleave, Andrea M.; Jones, James E.; McGlothlin, James D.; Saxen, Mark A.; Sanders, Brian J.; Vinson, LaQuia A.; Department of Pediatric Dentistry, IU School of DentistryIn this study, a mechanical model was applied in order to replicate potential surgical fire conditions in an oxygen-enriched environment with and without high-volume suction typical for dental surgical applications. During 41 trials, 3 combustion events were measured: an audible pop, a visible flash of light, and full ignition. In at least 11 of 21 trials without suction, all 3 conditions were observed, sometimes with an extent of fire that required early termination of the experimental trial. By contrast, in 18 of 20 with-suction trials, ignition did not occur at all, and in the 2 cases where ignition did occur, the fire was qualitatively a much smaller, candle-like flame. Statistically comparing these 3 combustion events in the no-suction versus with-suction trials, ignition (P = .0005), audible pop (P = .0211), and flash (P = .0092) were all significantly more likely in the no-suction condition. These results suggest a possible significant and new element to be added to existing surgical fire safety protocols toward making surgical fires the "never-events" they should be.Item Stainless Steel Crown Success Using the Hall Technique: A Retrospective Study(Elsevier, 2014-12) Ludwig, Kevin; Fontana, Margherita; Vinson, LaQuia; Platt, Jeffrey; Dean, Jeffrey; Department of Pediatric Dentistry, IU School of DentistryBackground In this retrospective study, the authors evaluated the clinical and radiographic success of stainless steel crowns (SSCs) used to restore primary molars with caries lesions, placed by means of both the traditional technique (involving complete caries removal and tooth reduction before placement of the SSC) and the Hall technique (involving no caries removal, no crown preparation and no use of local anesthetic before placement of the SSC). Methods The authors conducted a retrospective chart review by using the patient records at a private pediatric dental practice at which the Hall technique had been introduced in June 2010 as an alternative treatment to traditional SSC placement. The inclusion criteria were caries lesions on a primary molar with no clinical or radiographic evidence of pulpitis, necrosis or abscess, as well as follow-up of at least six months or until failure, whichever came first. They graded restoration success by using a four-point scale based on presence or loss of the SSC, and whether or not the patient needed further treatment associated with pulpal pathology or secondary caries. They collected and summarized patient demographic information. They used a Kaplan-Meier survival curve along with 95 percent confidence intervals to evaluate clinical success. Results The authors found that 65 (97 percent) of 67 SSCs placed with the Hall technique (mean observation time, 15 months; range, four-37 months) and 110 (94 percent) of 117 SSCs placed with the traditional technique (mean observation time, 53 months; range, four-119 months) were successful. Conclusion Findings of this study show a similar success rate for SSCs placed with the traditional technique or the Hall technique.Item Effect of human milk and its components on Streptococcus mutans biofilm formation(2015) Allison, Lesa M.; Walker, LaQuia A.; Sanders, Brian J.; Yang, Ziyi; Eckert, George; Gregory, Richard L.; Department of Pediatric Dentistry, IU School of DentistryObjective: This study investigated the effects of human breast milk and its components on the nutritional aspect of the caries process due to Streptococcus mutans UA159 biofilm formation. Study design: Human breast milk was collected from 11 mothers during 3-9 months postpartum. To test for the effect on biofilm formation, a 16-hour culture of S. mutans was treated with dilutions of human breast milk and several major components of human breast milk, lactose, lactoferrin, IgA, and bovine casein in sterile 96-well flat bottom microtiter plates for 24 hours. The biofilms were fixed, washed, stained with crystal violet, and extracted. Absorbance was measured to evaluate biofilm growth mass. Results: Dilutions 1:10-1:2,560 of the human breast milk samples increased biofilm formation by 1.5-3.8 fold compared to the control. Lactoferrin decreased biofilm formation significantly in all dilutions (average milk concentration of 3 mg/ml). Lactose had no effect at average breast milk concentrations (60 mg/ml) except at its lowest concentration (15 mg/ml) where it was increased. IgA significantly decreased biofilm formation at its highest concentration of 2,400 μg/ml (average milk concentration 600 μg/ml). Casein caused significantly increased biofilm formation at all concentrations tested above the average milk content (2.3 mg/ml). Conclusions: The results of this study demonstrate an increase in S. mutans biofilm formation by human breast milk 3-9 months post partum. Among its major components, only casein significantly increased biofilm formation among the concentrations analyzed. Lactose had no effect except at 15 mg/ml. Lactoferrin and IgA significantly decreased S. mutans biofilm formation at their highest concentrations. This information expands the current knowledge regarding the nutritional influence of breastfeeding and validates the necessity to begin an oral hygiene regimen once the first tooth erupts.Item Use of Cone-Beam Computed Tomography in Early Detection of Implant Failure(Elsevier, 2015-01) Yepes, Juan F.; Al-Sabbagh, Mohanad; Department of Pediatric Dentistry, IU School of DentistryItem Relationship between enamel fluorosis severity and fluoride content(Elsevier, 2016-03) Martinez-Mier, Esperanza A.; Shone, Devin B.; Ando, Masatoshi; Lippert, Frank; Soto-Rojas, Armando E.; Department of Pediatric Dentistry, IU School of DentistryOBJECTIVES: Enamel fluorosis is a hypomineralization caused by chronic exposure to high levels of fluoride during tooth development. Previous research on the relationship between enamel fluoride content and fluorosis severity has been equivocal. The current study aimed at comparing visually and histologically assessed fluorosis severity with enamel fluoride content. METHODS: Extracted teeth (n=112) were visually examined using the Thylstrup and Fejerskov Index for fluorosis. Eruption status of each tooth was noted. Teeth were cut into 100 μm slices to assess histological changes with polarized light microscopy. Teeth were categorized as sound, mild, moderate, or severe fluorosis, visually and histologically. They were cut into squares (2 × 2 mm) for the determination of fluoride content (microbiopsy) at depths of 30, 60 and 90 μm from the external surface. RESULTS: Erupted teeth with severe fluorosis had significantly greater mean fluoride content at 30, 60 and 90 μm than sound teeth. Unerupted teeth with mild, moderate and severe fluorosis had significantly greater mean fluoride content than sound teeth at 30 μm; unerupted teeth with mild and severe fluorosis had significantly greater mean fluoride content than sound teeth at 60 μm, while only unerupted teeth severe fluorosis had significantly greater mean fluoride content than sound teeth at 90 μm. CONCLUSIONS: Both erupted and unerupted severely fluorosed teeth presented higher mean enamel fluoride content than sound teeth. CLINICAL SIGNIFICANCE: Data on fluoride content in enamel will further our understanding of its biological characteristics which play a role in the management of hard tissue diseases and conditions.Item Florida child care center directors' intention to implement oral health promotion practices in licensed child care centers(BioMed Central, 2016-09-22) Joshi, Ajay; Ocanto, Romer; Jacobs, Robin J.; Bhoopathi, Vinodh; Department of Pediatric Dentistry, IU School of DentistryBACKGROUND: To determine the factors associated with child care center directors' (CCCDs) intention to implement oral health promotion practices (OHPPs) in licensed childcare centers (CCCs) within the next year, and their self-perceived barriers in successfully implementing those practices. METHODS: For this cross-sectional study, a pretested 45-item online survey was sent to 5142 CCCDs assessing pediatric oral health knowledge, attitudes towards oral health, intention to implement OHPPs, and self-perceived barriers to implementing OHPPs. An adjusted logistic regression model determined the factors associated with CCCDs intention to implement OHPPs within the next year. RESULTS: Participants were 877 CCCDs, with mean age of 48.5 ± 10.5 years, of whom 96 % were women, and 74 % were whites (Response rate = 19.4 %). The majority (67 %) of respondents reported that they intended to implement OHPPs in their center within a year. Insufficient funding, lack of enough training in oral health, and limited time to promote oral health were the most frequently cited barriers to implementing OHPPs. CCCDs of non-White race (p = 0.02), with a college degree or above (p = 0.05), and with positive attitudes (p < 0.0001), were more likely to report that they will implement OHPPs within the next year compared to their counterparts. CONCLUSIONS: CCCDs reported fewer barriers to implementing OHPPs within the next year, indicating that CCCs can be a suitable setting to promote oral health. CCCDs race, educational status and attitudes towards oral health strongly predicted their intention to implement OHPPs. Though this study assessed the intention of CCCDs to implement OHPPs in CCCs, it did not access the actual implementation of OHPPs by them. Therefore future research could longitudinally assess predictors for true implementation of OHPPs. In addition, researchers should adopt a more comprehensive, multi-level approach to assess the actual dental health needs of children attending these centers, along with parental, staff and center level characteristics, and other relevant factors related to implementing OHPPs.Item The Effect of DynaCleft® on Cleft Width in Unilateral Cleft Lip and Palate Patients(2017) Vinson, LaQuia A.; Pediatric Dentistry, School of DentistryObjective: The specific aim of this retrospective cross-sectional study was to assess the efficacy of DynaCleft® as a method of presurgical orthopedics with infants with a unilateral cleft lip and cleft palate who used an oral obturator. Study design: Data was collected from 25 infants all of comparable age diagnosed with a unilateral complete cleft lip and palate. Eight patients used DynaCleft ® and an obturator (Group Alpha) and seventeen patients only had an obturator (Group Beta). Maxillary impression casts were obtained from each patient at the initial clinic visit and at the time of cleft lip repair. Differences in alveolar cleft width were compared between the two groups. Casts were measured twice by one observer using a digital caliper. Results: Group Alpha began treatment on an average age of 24.25 days and Group Beta an average of 15.35 days of age. The average cleft width of Group Alpha was 8.13 mm and after treatment it was 4.59 mm. The average cleft width of Group Beta was 8.09 mm and 6.92 mm after treatment. Results of paired t-tests and two-sample t-test showed that cleft width changes between the two groups were significant (P = .03). Conclusions: DynaCleft ® significantly decreased the size of the alveolar cleft width compared to infants who did not use it. Providers should consider using DynaCleft® for patients who may not have access to infant maxillary orthopedics.Item In Vitro Effects of Sports and Energy Drinks on Streptococcus mutans Biofilm Formation and Metabolic Activity(AAPD, 2017) Vinson, LaQuia A.; Goodlett, Amy K.; Huang, Ruijie; Eckert, George J.; Gregory, Richard L.; Pediatric Dentistry, School of DentistryPurpose: Sports and energy drinks are being increasingly consumed and contain large amounts of sugars, which are known to increase Streptococcus mutans biofilm formation and metabolic activity. The purpose of this in vitro study was to investigate the effects of sports and energy drinks on S. mutans biofilm formation and metabolic activity. Methods: S. mutans UA159 was cultured with and without a dilution (1:3 ratio) of a variety of sports and energy drinks in bacterial media for 24 hours. The biofilm was washed, fixed, and stained. Biofilm growth was evaluated by reading absorbance of the crystal violet. Biofilm metabolic activity was measured by the biofilm-reducing XTT to a water-soluble orange compound. Results: Gatorade Protein Recovery Shake and Starbucks Doubleshot Espresso Energy were found to significantly increase biofilm (30-fold and 22-fold, respectively) and metabolic activity (2-fold and 3-fold, respectively). However, most of the remaining drinks significantly inhibited biofilm growth and metabolic activity. Conclusions: Several sports and energy drinks, with sugars or sugar substitutes as their main ingredients inhibited S. mutans biofilm formation. Among the drinks evaluated, Gatorade Protein Recovery Chocolate Shake and Starbucks Doubleshot Energy appear to have cariogenic potential since they increased the biofilm formation and metabolic activity of S. mutans.Item Prescription of Panoramic Radiographs in Children: A Health Services Assessment of Current Guidelines(American Academy of Pediatric Dentistry, 2017) Yepes, Juan F.; Powers, Elizabeth; Downey, Tim; Eckert, George J.; Tang, Qing; Vinson, LaQuia; Maupomé, Gerardo; Pediatric Dentistry, School of DentistryPurpose: To (1) determine adherence to guidelines when prescribing panoramic radiographs (PR) for patients 18 y.o. and younger; and 2) compare PR prescriptions between general dentists (GPs) and pediatric dentists (PDs). Methods: A retrospective analysis of insurance claims included codes for PRs and associated codes for two cities between 2008 and 2015. Chi-square tests ascertained the likelihood of a PR being associated within three days of routine exams. Results: A total of 81,699 pediatric patients were seen by 2,077 GPs and 103 PDs. There were 11,993 PRs, 119,068 routine exams (7,343 associated with a PR), 13,819 orthodontic procedures (378 associated with a PR), 798 third molar procedures (172 associated with a PR), and 16,636 procedures for acute problems (1,670 associated with a PR). Patients aged eight years old and younger had the largest discrepancy between GPs and PDs. GPs prescribed proportionally more films in patients five years old and younger, but PDs prescribed more in seven and eight year olds. Nine- to 18 year olds. had more similar patterns between GPs and PDs, except for 14- to 15 year olds, when GPs prescribed more. Conclusions: GPs prescribed PR in patients younger than five years old more often and were somewhat less likely to follow guidelines.
