This study used the 6-minute walk test to assess physical proficiency in children and adolescents with a diagnosis of mouth breathing (MB) versus those who demonstrated nasal breathing (NB). Testing revealed that MB had a significant negative impact on male patients. While female MB patients showed a clinical reduction in measures of physical proficiency compared with female NB patients, the differences were not statistically significant.

The objective of this study was to validate the usefulness of the W-index (WI) for screening patients at risk of osteoporosis by correlating WI results with those obtained from peripheral dual-energy X-ray absorptiometry. The results indicated a significant but negligible correlation between the methods. The WI values were able to differentiate patients with normal bone mineral density or osteopenia from patients with osteoporosis, suggesting that the WI is an easy, convenient osteoporosis screening tool.

This case report describes a minimal intervention approach for treating a tense-cooperative 7-year-old boy with a hypoplastic enamel defect in an incisor as a result of a traumatic dental injury to its predecessor. A temporary restoration was placed due to the child’s behavior and the eruption stage of the tooth. The procedure was performed without local anesthetic, utilizing a resin-modified glass ionomer cement and cotton roll isolation. This patient-friendly approach resulted in a satisfactory temporary restoration.

This report describes a case of composite resin recontouring to correct the morphology of the anterior teeth through the closure of diastemas. Minimal strategic contouring with composite resin proved to be a viable and conservative solution to close interdental spaces, restoring the smile harmony without dental overcontouring, thereby contributing to the health of periodontal tissues.

Intrapulpal and buccal temperatures were measured during in-office bleaching with carbamide peroxide prepared with or without titanium dioxide (TiO2) and applied with or without activation by a hybrid light. Activation with the hybrid light significantly increased buccal and intrapulpal temperatures during bleaching, particularly when carbamide peroxide was combined with TiO2, and these changes could exceed the 5.5°C limit for safe temperature increases.

The purpose of this in vitro study was to quantify and compare the quality of the marginal seal when different materials and bonding techniques were used to restore endodontic access cavities in zirconia cylinders. Glass ionomer cement provided inferior microleakage prevention. Direct composite resin restorations and zirconia inlays offered favorable results, and aluminum oxide air abrasion of the zirconia surfaces showed the potential to enhance marginal seal.

This article details the case of a patient presenting with yellow discoloration of the floor of the mouth and yellow pigmentation of the soft palatal mucosa due to a beta carotene–rich diet. Attending clinicians should seek clinicopathologic correlations of yellow mucocutaneous discoloration, most notably jaundice associated with hepatitis.

Treatment of labial hemangiomas, which are benign vascular tumors, may be challenging for functional and esthetic reasons. A labial hemangioma in a 12-year-old boy did not initially respond to sclerotherapy, but multimodal treatment with arteriography, percutaneous embolization, and esthetic surgery provided excellent esthetic results.
