Segmental odontomaxillary dysplasia (SOD) is an uncommon and likely underrecognized developmental condition. In rare cases, SOD can also result in anomalies of the ipsilateral mandibular alveolar process and teeth. This report presents two cases of SOD with mandibular involvement to highlight this potential variation in SOD presentation. These cases help shed new light on our understanding of the disease mechanism and pathoetiology, while also informing clinicians to be diligent in imaging the ipsilateral mandible for dental anomalies in their patients with SOD. Based on the involvement of both jaws, the name change to 'segmental ipsilateral odontognathic dysplasia' is justified to better reflect its pathophysiology.

Purpose: To investigate the prevalence of positive or potential sleep-disordered breathing (SDB) in children ages seven to 10 years during two time periods: pre- and postCOVID-19 lockdown. Methods: Two groups of children with mixed dentition were consecutively recruited from two private pediatric dental practices in Southwestern Pennsylvania. All parents or guardians of the children were asked to complete the 22-question Pediatric Sleep Questionnaire (PSQ) as part of the routine medical history examination. High risk was defined as positive answers to 33 percent or more of the questions answered. Results: The overall sample had 183 males and 183 females. Between August 2016 and December 2017, the pre-COVID-19 lockdown period (PREL), 218 children were surveyed consecutively; 148 children were surveyed consecutively between September 2020 and March 2021, in the post-COVID-19 lockdown period (POSTL). Screening utilizing the PSQ identified 16.2 percent as high risk of SDB POSTL in contrast to 5.0 percent observed PREL (95 percent confidence interval [95% CI]=1.6 to 6.4; Pearson's chi-square test, P<0.001). There were no associations between sex or body mass index and high risk of SDB due to the lockdown. Conclusion: The results suggest a three-fold increase in the prevalence of positive or potential SDB subsequent to the commencement of the COVID-19 lockdown for this age group.

Full-coverage restorations are indicated for posterior primary teeth as definitive treatments for high caries-risk children and in patients whose treatment is being performed under general anesthesia. Advances in biomaterials and parental preferences have driven interest in esthetic full coverage treatment options for primary posterior teeth. The prefabricated resin crown offers a 'flex fit' adaptation over the anatomic cervical convexity of the primary clinical crown, similar in functionality to a stainless steel crown. A new commercial product, BioFlx, hopes to address the ductility, color stability and durability concerns that glass fiber-reinforced composite crowns have while maintaining the enticing clinical aspects, namely the flex fit, esthetic appearance and more conservative tooth preparation when compared to pediatric zirconia crowns. The purpose of this case report is to describe an alternative restorative material that can be employed to deliver an esthetic full coverage solution in a child with a potential nickel allergy.

Purpose: To understand the relationship and impact of the parenting styles of mothers on the behavior and anxiety in the dental operatory of eight- to 12-year-old children. Methods: A cross-sectional study was conducted with 50 mother-child dyads. A short version of the Parenting Styles and Dimensions Questionnaire was used to assess parenting style, while the Modified Dental Anxiety Scale and Frankl's Behavior Rating Scale were used to assess dental anxiety and behavior. Results: Forty-six percent of children (n=23) were male. Sixty-four percent of mothers had an authoritative parenting style, 20 percent were authoritarian and 16 percent had a permissive parenting style. A statistically significant negative relationship was observed between permissive parenting style (-0.392, P<0.005) and dental behavior, and between dental behavior and dental anxiety (-0.611, P<0.000). Regression analysis showed that parenting style had an impact of 14.5 percent on the behavior of the child in the dental operatory. Conclusion: Parenting styles, particularly permissive types, had a significant impact on a child???s dental behavior.

Purpose: To examine the influence of substituting intranasal (IN) midazolam (MID) for oral (PO) MID, within the three-drug combination of meperidine (MEP), hydroxyzine (H) and MID, on sedation treatment outcomes. Methods: A retrospective, cross-sectional analysis examined patient variables and sedation outcomes in 508 pediatric dental patients sedated by single- and multi-drug sedation regimens (MEP-H; MEP-H-(PO)-MID; MEP-H-(IN)-MID; single-agent MID). The outcome assessment examined sedation visit effectiveness, sedation treatment completion, treatment time and medication administration to discharge time. Multivariable logistic regression analyses assessed predictive variables associated with sedation visit effectiveness. Results: Both three-drug combinations (MEP-H-(PO)-MID; MEP-H-(IN)-MID) were used for behavior guidance in children of a similar age (median age=7.1 and 6.5 years, respectively, for the two drug combinations) and weight (median weight = 23.7 and 23.5 kg, respectively, for the two drug combinations). These three-drug combinations had a higher likelihood of sedation effectiveness over the reference sedation regimen of single-agent midazolam (MEP-H-(PO)-MID adjusted odds ratio [OR] = 2.65; 95 percent confidence interval [95% CI]=1.09 to 6.45; P=0.032; and MEP-H-(IN)-MID OR=2.08; 95% CI=1.03 to 4.18; P=0.039). MEP-H-(IN)MID was associated with a shorter medication administration to discharge time for patients by 23 minutes (interquartile range [IQR]=9.5 to 34 minutes) compared to MEP-H-(PO) MID (P<0.05) while providing a comparable number of teeth treated (median=five). All sedation drug regimens, including MEP-H-(IN)MID, had high levels of oxygen saturation during all sedation appointments. Conclusion: Substituting IN for PO MID in MEP-H-MID was associated with a shorter total time to discharge while demonstrating comparable efficacy during sedation.
