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 present evidence-based recommendations on nonpharmacological behavior guidance for the pediatric dental patient. Methods: The work group assessed eight systematic reviews for effectiveness of nonpharmacological behavior guidance techniques in children undergoing preventive care or a dental treatment visit. The key outcomes assessed included cooperative behavior, anxiety, and procedural pain. To formulate the recommendations, the work group used the GRADE framework to obtain consensus on domains such as priority of the problem, certainty of the evidence, balance between desirable and undesirable consequences, patients’ values and preferences, acceptability, and feasibility. Results: Overall, the use of basic nonpharmacological behavior guidance techniques resulted in trivial-to-small effect on improvement in behavior or reduction in anxiety. However, for children and adolescents undergoing preventive care, mobile applications and modeling showed large effects in reduction of anxiety. For those undergoing dental treatment, strategies such as modeling, positive reinforcement, biofeedback relaxation, breathing relaxation, animal-assisted therapy, combined tell-show-do, audiovisual distraction, and cognitive behavior therapy showed large reduction in anxiety. For children and adolescents with special health care needs, audiovisual distraction and sensory-adapted dental environment showed large reduction of anxiety. Conclusions: All the formulated recommendations were conditional and were mostly based on very low certainty of evidence. Conditional recommendations imply that different choices or combinations of behavior guidance techniques may be most appropriate for different patients. Clinicians should use techniques consistent with the parent/patient values and preferences. These recommendations are based on the best available evidence to-date and are intended to aid clinical decision making. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this descriptive study was to describe oral manifestations and oral health quality of life (QOL) in children aged six months to six years, 11 months with tuberous sclerosis complex (TSC). Methods: Parents of participants completed an oral health QOL survey. The presence of oral lesions associated with TSC was assessed. Results: Sixty-two participants enrolled between February 2015 and March 2017. Among the significant oral health findings, 11 (17.7 percent) had enamel pitting, 33 (53 percent) had no previous dental examination, eight (12.9 percent) did not brush their teeth, and eight (12.9 percent) had caries present. Per the QOL survey results, 18 (31 percent) had difficulty sleeping, 22 (37.3 percent) experienced irritability/frustration, and 15 (29.4 percent) had difficulty pronouncing words. Developmental delays were present in 40 (70.2 percent), seizures occurred within the last three months in 37 (59.7 percent), and a mammalian target of rapamycin inhibitor medication was used for 22 (35.4 percent). Conclusions: Enamel pitting was observed in 17.7 percent of children in the primary dentition. Oral health quality of life in this tuberous sclerosis complex cohort was significantly reduced.

Purpose: The purpose of this study was to survey the membership of the American Academy of Pediatric Dentistry (AAPD) and determine the current status of nitrous oxide (N2O) utilization in their dental practices while also comparing the findings to a similar survey completed 20 years ago. Methods: A 55-item questionnaire on the use of N2O was sent to the AAPD membership. Results: The total number of respondents was 1,632 (26 percent). Sixty-two percent are board-certified, 97 percent use N2O in their office, 18 percent indicated greater than 80 percent of their patient pool required N2O versus six percent in 1996. Fifty percent of parents expressed concerns about N2O use. Conclusions: Changes have occurred in the use of nitrous oxide since 1996, including: (1) a greater percentage of practitioners using N2O; (2) perceptions that more pediatric patients need N2O: (3) a shift in use of N2O by duration of practitioner experience; (4) an increased percentage of board-certified respondents: and (5) possible increasing parental concerns about N2O.

Purpose: To assess the effectiveness of nonpharmacological behavior guidance interventions used for children and youth with special health care needs (CYSHCN) during preventive and dental treatment visits. Methods: Databases: Ovid MEDLINE, PsyclNFO (EBSCOhost), Embase, and Cochrane Library, were searched from 1946 to February 2022, for randomized clinical trials (RCTs) comparing effectiveness of basic and advanced nonpharmacological techniques rendered during a preventive visit (exam, fluoride application, radiographs, and prophylaxis) or a treatment visit (simple surgical treatment, sealants, restorative care with or with local anesthesia) with control or other interventions. The primary outcome measures for the studied interventions were reduction in anxiety, fear, pain, and improvement in cooperative behavior. Eight authors determined the included Randomized Controlled Trials (RCTs), performed data extraction, and assessed the risk of bias (ROB). Standardized Mean Difference calculation and assignment of quality of evidence by Grading of Recommendations Assessment, Development and Evaluation approach were done. Results: Eleven articles qualified for analysis from 219 screened articles. Included studies evaluate the effectiveness of in office strategies such as modeling, audio-visual distraction, sensory adapted dental environment, and picture exchange communication system. The certainty of evidence ranged from Very low to Low and the magnitude of effect varied from trivial to large change in the desired outcomes. Conclusions: Most basic non-pharmacological behavior guidance techniques showed some trivial to small reduction in self-reported anxiety and/ or improvement in behavior, with audiovisual distraction, Sensory Adopted Dental Environment, and Picture Exchange Communication System showing large reduction in anxiety based on some rating scales.

Purpose: To assess the effectiveness of nonpharmocological behavior guidance interventions used for children undergoing dental treatment visits. Methods: Databases: Ovid MEDLINE, PsycINFO (EBSCOhost), Embase, and Cochrane Library, were searched from 1946 to February 2022, for randomized clinical trials (RCTs) comparing effectiveness of basic and advanced nonpharmocological techniques rendered during a dental . treatment visit including sealants, restorative core, dental local anesthesia, and simple surgical procedures. The primary outcome measures were reduction in anxiety, fear, pain, and improvement in cooperative behavior. Eight authors determined the included RCTs, performed data extraction, and assessed the risk of bios (ROB). Standardized Mean Difference calculation and assignment of quality of evidence by Grading of Recommendations Assessment, Development and Evaluation approach were done. Results: Forty articles qualified for analysis from 219 screened articles. Included studies evaluated the effectiveness of pre-visit preparation and in office strategies rendered pre-/post- or during treatment such as positive imagery, direct observation/modeling, desensitization, tell-show-do and its modifications, voice control, positive reinforcement, memory restructuring, bio-feedback and breathing relaxation, animal assisted therapy, combined therapies, and cognitive behavior therapy. The certainty of evidence ranged from Very low to high and the magnitude of effect varied from trivial to large change in the desired outcomes. Conclusions: Most of the basic non-pharmacological behavior guidance techniques showed trivial to small reduction in self-reported anxiety and/or improvement in behavior, with modeling, positive reinforcement, biofeedback relaxation, breathing relaxation, animal assisted therapy, combined tell-show-do and audiovisual distraction, and cognitive behavior therapy showing large effects in reduction of anxiety based on some scales.

Purpose: To assess the effectiveness of nonpharmacological behavior guidance interventions used for a child undergoing preventive dental visits. Methods: Databases: Ovid MEDLINE, PsyclNFO (EBSCOhost), Embase, and Cochrane Library, were searched from 1946 to February 2022, for randomized clinical trials (RCTs) comparing effectiveness of basic and advanced nonpharmacological techniques rendered during a preventive visit including examination, prophylaxis, fluoride application and radiographs. Workgroup (WG) identified moderate-to-high quality systematic reviews (SRs) published on hypnosis, audiovisual distraction, and parental presence/absence; and decided to exclude these interventions from current SR to avoid duplication. The primary outcome measures for the studied interventions included reduction in anxiety, fear, pain, and improvement in cooperative behavior. Eight authors determined the included RCTs, performed data extraction, and assessed the risk of bias. Standardized Mean Difference calculation and assignment of quality of evidence by Grading of Recommendations Assessment, Development and Evaluation approach were done. Results: Fifteen articles qualified for analysis from 219 screened articles. WG found studies evaluating effectiveness of pre-visit preparation and in-office strategies rendered pre- or during treatment such as positive imagery, communication, modeling, tell-show-do, magic tricks, mobile applications, positive reinforcement, and sensory adapted dental environment. The certainty of evidence ranged from Very low to Moderate and the magnitude of effect varied from trivial to a large change in the desired outcomes. Conclusions: Most basic nonpharmacological behavior guidance techniques showed trivial to small reduction in self-reported anxiety and/or improvement in behavior, with mobile application and modeling showing large effects in reduction of anxiety based on some rating scales.

Purpose: To assess the diagnostic confidence of intraoral radiographic image quality while reducing the pediatric patient's radiation exposure using a longer position indicating device (PID), additional X-ray beam filtration and rectangular collimation while using modern, lower-power intraoral dental X-ray units. Methods: A randomized prospective study scored bitewing intraoral dental images based on relevant clinical features. Observer studies with pediatric dentists and dental residents were conducted to verify whether diagnostic confidence remained unchanged after dose reduction modifications. The study involved a two-phase investigation to determine: (1) the best thickness of aluminum (Al) 2024-T3 alloy filter and (2) required increased exposure time to maintain intraoral radiographic image quality. A 30 cm PID with a rectangular collimator was used to further manage patient dose. For each phase, images from 125 patients were collected from February 2017 to September 2018 and analyzed. Results: The results from the observer study using a 30 cm PID, 1.02 mm thick Al alloy filter, and a rectangular collimator resulted in a patient dose reduction between 64 percent (exposure time of 400 msec) to 77 percent (250 msec), without any statistically significant effect to the diagnostic confidence of the observers in evaluating the reduced radiation images. Conclusion: Long recognized dose reduction methods, when implemented on a modern, low-power intraoral dental X-ray unit, do not impact confidence in bitewing diagnostic images, but substantially reduce patient dose and should be adopted to increase patient safety, especially for children.

Purpose: The purpose of this study was to investigate whether primary molars treated with composite resins (CRs) and stainless steel crowns (SSCs) during an oral rehabilitation under general anesthesia (GA1) required retreatment at a second oral rehabilitation under GA (GA2). Methods: Records were examined from 296 healthy patients with more than one dental rehabilitation under general anesthesia from June 2012 to January 2019. Data included treatment details and demographic information. Frequencies and means were recorded. An analysis was completed using logistic regression and chi-square for categorical variables. Results: For primary first molars, 43 percent of CRs placed at GA1 were treated with SSCs at GA2. For primary second molars, 35 percent of CRs placed at GA1 were treated with SSCs at GA2. There was no statistically significant difference in retreatment rates by molar type (P equals 0.27). Eight percent of SSCs placed on any molar at GA1 required retreatment at GA2. Conclusions: Primary molars treated with stainless steel crowns using general anesthesia had the lowest percentage of retreatment compared to those treated with composite resins. Strong consideration should be given to the placement of SSCs on primary molars in patients with early childhood caries under general anesthesia. Placement of primary molar SSCs during initial treatment under general anesthesia may reduce the need for additional treatment in the future. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to assess the prevalence of traumatic dental injuries (TDIs) in the primary dentition that presented to the emergency department (ED) of a level-one trauma center at a children's teaching hospital. Methods: Electronic health records of 1,170 patients with 2,746 traumatic dental injuries who presented to the ED over a 55-month period were reviewed in this retrospective cohort study. A subset of these (541 patients) with multiple injuries in primary teeth were examined. Results: The prevalence of primary tooth injury was 41 percent (1,120 out of 2,746). Most injuries were sustained by males (N equals 311; 57 percent); lateral luxations (N equals 341; 30 percent) were the most common injuries to the primary dentition. The primary maxillary central incisors were the most common teeth to be injured. Concomitant injuries were reported in 50 (4.5 percent) primary teeth. Conclusions: Traumatic dental injuries occurred frequently in the primary dentition, with lateral luxations being reported most often. Over 40 percent of all reported TDIs occurred in the primary dentition. Emergency room providers should be prepared to manage primary tooth TDIs. [ABSTRACT FROM AUTHOR]

A 13-year-old female presented with traumatized maxillary central incisors that had been endodontically treated. Five years later, at a different dental office, she had the clinical crowns removed, leaving subgingival margins. From the patient's history and our initial assessment, it seemed as if the teeth had been fractured and luxated but not avulsed. Endodontic posts with spot-welded orthodontic brackets were temporarily cemented to enable orthodontic extrusion. Once access to restorable margins was obtained, the temporary posts were removed and conventional fiber posts with interim composite crowns were placed. The restorations were still satisfactory at the one-year follow-up, with a healthy periodontium, intact apical seal, and no signs of external resorption observed. Combined specialty treatment provided an esthetically acceptable outcome in a difficult restorative situation for a growing child. The purpose of this case report is to discuss an interim treatment until the child reaches dentofacial maturity, when definitive restorations can be provided. [ABSTRACT FROM AUTHOR]

Background & Purpose: Accurate radiographic assessment of secondary alveolar bone grafting (SABG) is critical in evaluating SABG outcomes in patients with cleft lip and palate. This study compared Periapical (PA) and Cone beam computed tomography (CBCT) grading of SABG outcomes and conducted an analysis of agreement rate between the two imaging modalities., Methods: A retrospective chart review was performed of patients who underwent secondary alveolar bone grafting at a single institution. Bone quality of the alveolar cleft site was assessed at three root levels of the adjacent teeth on PA and CBCT images., Results: 48 patients had pre- or post-operative images with both CBCT and PA that were appropriate for comparison. A total of 174 alveolar bone sections (three root levels of adjacent teeth in 58 pairs) were graded on CBCT and PA images. Agreement of CBCT grading with PA grading was 41.3% (72/174) overall. CBCT assessments rated bone quality lower than PA grading in 51.2% (89/174) of sections. CBCT had higher grading than PA image grading in 7.5% (13/174) of sections. The weighted Cohen Kappa value for comparison of CBCT and PA readings was 0.17, indicating a low rate of agreement. Wilcoxon signed rank test demonstrated that the difference between grading on CBCT and PA assessments was statistically significant ( P  < .001)., Conclusions: CBCT and PA readings demonstrated an overall low rate of agreement in the assessment of cleft alveolar bone. This investigation suggests that PA radiographs have lower sensitivity in detecting poor bone grafting outcomes., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.
