Purpose: To evaluate descriptively and quantitatively teeth affected by enamel hypomineralization (EH) using optical coherence microtomography (OCT). Methods: Twenty teeth were classified according to the European Academy of Pediatric Dentistry's molar incisor hypomineralization (MIH) index and separated into groups according to the degree of EH severity. For each tooth, scans were performed on both the affected and the non-affected areas, and their corresponding optical images were captured. Results: In the qualitative analyses, in most of the images bright lines were observed in relation to the enamel surface and a high level of photon scattering immediately below the enamel surface. This showed that the shading distribution can be identified as hypomineralized areas in which the scattering signal can be used as a diagnostic criterion. In the quantitative analyses, Tukey's test was performed to evaluate the means of the optical attenuation coefficient, which did not present significant differences. However, considering the correlation, homogeneity and contrast analyses, a statistically significant difference was observed between the groups. The group with severe MIH showed greater homogeneity and correlation, but less contrast. Conclusion: Currently, MIH has its severity measured by essentially clinical means. OCT processing techniques reveal advances in the diagnostic imaging of MIH, showing that image texture analysis can be a promising and useful method to aid in its diagnosis.

The use of animal-assisted therapy (AAT) in pediatric dental practices is a relatively new approach for behavior management, with few studies gauging interest in its use from the provider's perspective. The purpose of this study was to assess pediatric dentists' interest in and concerns with the use of AAT and identify its challenges and limitations. A survey was sent to the membership of the American Academy of Pediatric Dentistry, comprising questions about providers' practices and their views on the benefits of and concerns about implementing AAT. Ninety-two percent of the respondents felt that pet therapy would improve a patient's comfort; 67 percent indicated they expected a moderate or strong improvement, but only eight percent expected no improvement. Hygiene (26 percent) and liability (26 percent) were the main reservations about its use. This paper illustrates that the profession is open to AAT for behavior guidance and offers ways to incorporate it into practice.

Mandibular fractures are rare in children and normally result from high-impact trauma. Clinical protocols have evolved in recent years, especially after the introduction of rigid internal fixation methods and the development of novel resorbable materials. The purpose of this report is to present the case of a three-year-old toddler who fell from a bunk bed at home, resulting in a unilateral fracture of the mandibular parasymphysis and a joint fracture on the left side. The patient was treated under general anesthesia with rigid internal fixation with biodegradable plates and screws. Pediatric patients can benefit from resorbable materials, especially their faster mobilization and avoidance of secondary removal operations. Self-reinforced fixation devices are safe and efficient for the treatment of pediatric mandible fractures. However, further clinical investigations are needed to evaluate long-term reliability.

Purpose: It has been suggested that follow-up visits for pediatric patients after full-mouth dental rehabilitation (FMDR) under general anesthesia (GA) are important to evaluate healing and restorative treatment, review oral hygiene instruction, provide nutritional counseling and address guardians' concerns. The purpose of this study was to evaluate pediatric dentists' current utilization of follow-up visits after GA and to evaluate pediatric dentists' and guardians' perceptions of their purpose and value. Methods: Three separate surveys were administered: (1) pediatric dentist survey, (2) guardian pre-appointment survey and (3) guardian post-appointment survey. The guardian surveys examined their perceptions of a follow-up visit before and after FMDR under GA. The pediatric dentist survey examined current utilization and perception of follow-up appointments. Results: Most clinicians (72 percent) reported scheduling a follow-up visit. Providers generally agreed that the post-operative appointments were important (69 percent). Of the guardians who attended the follow-up visit, 96.3 percent agreed that the post- operative visit was useful. Conclusion: Both pediatric dentists and guardians of patients undergoing FMDR under GA agreed that a follow-up visit after GA was valuable despite low complication rates.

Infraocclusion is a local etiologic factor of malocclusion that can have deleterious effects on normal dental development. Therefore, early recognition and diagnosis are the two most important factors in the management of infraocclusion. The purpose of this case report is to describe the management of a patient who was diagnosed at seven years of age with an eruption disturbance, whose severe sequela could have been prevented had the infraocclusion been diagnosed early.

Chemical burn of the oral mucosa can occur as a result of the inadvertent, intentional or iatrogenic use of chemicals. Self-treatment for toothache relief with nonpharma ceutical substances can result in a chemical burn. A detailed history is paramount in such cases to identify the etiologic agent to proceed with appropriate treatment. The purpose of this report is to describe the case of an eight-year-old with a complaint of toothache who rinsed his mouth with potassium aluminium sulfate solution to achieve pain relief. This caused ulceration of the attached gingiva and oral mucosa and necrosis of the alveolar bone surrounding the offending tooth, leading to its mobility. This case highlights the disastrous consequences of inappropriate self-treatment to achieve pain relief from toothache.

Purpose: To create and validate size guides for fitting Denovo^® plain molar bands and bands with tubes to 3M^™ ESPE^™ stainless steel crowned primary molars. Methods: Two size guides were created for fitting these bands to corresponding crown sizes, with an additional pre-existing guide available for comparison. Eight volunteer dentists chose their best-fit band sizes for stainless steel crowned typodont teeth, with each seeing a subset of clinical conditions as determined by a randomized factorial experiment. Comparisons of dentists' best fits and each guide individually were evaluated for over 96 fits for robustness of clinical condition in an analysis of variance and agreement using intraclass correlation. Savings in attempted fits using size guides were estimated. Results: No significant differences over clinical conditions were observed when evalua- ting size guides and dentists' best fits. Intraclass correlations between plain band, plain band with tubes, and the pre-existing plain band with tubes guides and observed fits were 0.997, 0.998 and 0.998, respectively, with corresponding expected savings of 1.1, 0.7 and 0.5 attempts per fit, respectively. Conclusion: Size guides created for fitting plain bands and bands with tubes to stainless steel crowned primary molars were validated by volunteer dentists and showed promise for decreasing waste and increasing efficiency during dental visits.).

Purpose: To assess the effect of rapid maxillary expansion (RME) on the inflammatory and stress response of patients undergoing orthodontic treatment. Methods: Eighty salivary samples were collected from patients (n=16) during RME at five moments: before the expander placement (T1); 25 minutes after its first activa- tion (T2); seven days after placement, shortly after the patient arrived at the dental clinic (T3); 25 minutes after the appliance activation on day seven (T4) and one month after the last activation of the appliance (T5). Cortisol and nitric oxide levels were evaluated using an immunoassay kit and the Griess method, respectively. Friedman and Wilcoxon tests were used for statistical analysis (P <0.05). Results: Participants' mean age was 11.5 years. There was a significant change in cortisol levels over the study period in the total sample (P<0.01), for the Haas appliance (P=0.01), female sex (P=0.01), younger children (P=0.01), presence of large overbite (P=0.02), presence of posterior crossbite (P =0.006), Class I type occlusion (P=0.02) and mesofacial facial type (P =0.02). Regarding nitric oxide, there was a significant change over the study period in those who wore the Haas appliance (P =0.04). For nitric oxide levels, T1 was significantly higher than T3, T4 and T5 (P <0.05) for those who wore a Haas appliance. Conclusion: The period anticipating the consultation at the waiting reception area was more stressful than the dental procedure in patients undergoing RME. This procedure did not cause alterations in salivary biomarkers related to inflammation.

Ankyloglossia is a developmental anomaly characterized by a shortened lingual frenulum, which can range from cases with no clinical relevance to severe cases, where frenectomy may be indicated. In newborns, this indication has increased exponentially. The purpose of this report is to discuss obstruction of the sublingual caruncle, with a recurrent ranula, as a post-surgical complication of laser lingual frenectomy performed in a newborn. The treatment provided is also discussed (marsupialization and removal of the affected sublingual glands). Lingual frenectomy should be performed with great care, especially in newborns, because the sublingual caruncles can be affected and complications can occur.

Purpose: To examine the impact of dental operatory room color on the level of anxiety in committed youth at a juvenile correctional center. Methods: A randomized controlled trial was conducted at a juvenile correctional center using an approved continuous quality assurance survey. The dental assistant collected self-reported anxiety scores from 164 individuals alternating between two dental operatory rooms. One dental operatory room was painted with color while the other dental operatory room was unaltered (white). Repeated measures linear models were used to test for associations between visit type, visit number and operatory. Results: For 65 percent of visits, little to no anxiety was reported. Among the remaining visits, anxiety scores were on average 1.13 points higher across all appointment types in the non-colorful operatory room but were not statistically significant (P=0.1373, 95 percent confidence interval [95% CI] = -0.37 to 2.63). Anxiety scores were, on average, 1.7 points higher in the non-colorful room when selected for more anxiety- inducing restorative or emergency appointments (P=0.4371, 95% CI = -1.37 to -4.82), which indicated some clinical significance but was not statistically significant. Conclusion: The color of a dental operatory room did not have a statistically significant effect on lowering the level of anxiety in incarcerated youth but may have a clinically significant effect that should be further researched.
