    Management of Two Cases of Supernumerary Teeth
    (IngentaConnect, 2020-01-01) Scully, Allison; Zhang, Hong; Kim-Berman, Hera; Benavides, Erika; Hardy, Nina C.; Hu, Jan C-C.; Pediatric Dentistry, School of Dentistry
    Supernumerary teeth are commonly observed as an isolated developmental anomaly. While familial tendency of supernumerary teeth has been documented, its genetic causality has not yet been determined. This communication presents two cases with supernumerary teeth and the process leading to the diagnosis and determination of their underlying conditions. Cases were evaluated and family histories reviewed. Genetic counseling was recommended for the probands and followed by genetic testing of selected family members. Results The proband of family 1, who has multiple supernumerary teeth, was determined to have a RUNX2 missense mutation (c.379C>T, p.Pro127Ser) and diagnosed with cleidocranial dysplasia. The proband of family 2 who has a premolar region supernumerary tooth and was reported to have no bone defects also presented with a RUNX2 missense mutation (c.1381G>C, p.Gly461Arg). Conclusion When patients present with multiple supernumerary teeth, a recommendation and guidance to genetic counseling and testing may facilitate accurate diagnosis and management.

    Patterns of radiograph use in a population of commercially insured children
    (Elsevier, 2022-05) Fontana, Margherita; Yepes, Juan F.; Eckert, George J.; Hale, Kevin J.; Benavides, Erika; Pediatric Dentistry, School of Dentistry
    Background The objective of this study was to evaluate differences in number and type of radiographs used among 3 age groups (0-5, 6-12, 13-18 years) by general dentists, pediatric dentists, and other specialists, and to determine the association between number and type of radiographs and clinical need. Methods A retrospective analysis of insurance claims by age group and oral health care provider type included children aged 0 through 8 years in 2005 who had a minimum of 10 years of continuous eligibility. Indicator claim variables were calculated to identify high-risk, high-need patients. Results A total of 6,712,155 records from 105,010 patients and 34,406 providers were analyzed. There was a significant effect (P < .001) of age on the number of radiographs obtained per visit. The estimated rates of radiographs per visit for ages 0 through 5, 6 through 12, and 13 through 18 were 0.373, 0.492, and 0.393, respectively. There was a significant interaction effect between age and provider type. For patients younger than 13 years, general dentists had lower rates of obtaining radiographs than did pediatric dentists, with no significant difference between providers for the 13- through 18-year age group. Treatments received, except for extractions and prosthodontics, were significantly associated with rate of radiographs per visit, with “number of restorations” as an indicator of increased risk, need, or both showing an inverse association with radiograph use. Conclusions Child age and provider type had an effect on number of radiographs obtained per visit. Lack of caries diagnostic codes and uncommon use of risk codes hindered interpretation of whether use, frequency, or both is associated with need. Practical Implications Radiograph use should follow existing guidelines or recommendations based on clinical need.
