This study examined the effect of the thickness of ultratranslucent lithium disilicate and third-generation zirconia ceramic discs (0.5 vs 1.5 mm) on the bond strength of resin cement following 24 hours and 6 months of water storage. Thicker zirconia discs showed the highest bond strength. Although the bond strength of zirconia decreased over time, 1.5-mm discs still showed greater strength than 1.5-mm lithium disilicate discs at 6 months. The values for lithium disilicate were stable.

An in vitro experiment assessed the effect of polishing protocols on the surface roughness of microhybrid and nanohybrid composite resins. For both materials, delayed polishing following 24-hour immersion in distilled water significantly reduced the surface roughness compared with immediate polishing, but nanohybrid specimens showed superior smoothness with both protocols.

This article illustrates an alternative technique for closure of small diastemas (2 mm or less) by applying orthodontic elastics directly on the central incisors without the use of esthetic buttons or removable trays. Once the desired space closure is achieved, the corrected position of the incisors can be retained with a resin-bonded splint to counter labial tipping movement and aid in root alignment.

Maxillary canine impaction is a relatively common eruption disturbance that can compromise smile esthetics and functional occlusion. A case report describes an interdisciplinary approach to treating a palatally impacted maxillary canine in a 16-year-old girl, highlighting space creation, conservative palatal exposure, controlled orthodontic traction, and radiographic surveillance throughout active eruption.

Clinical, radiographic, surgical, and histopathologic images document a case of a compound odontoma arising in the mandibular anterior region. The lesion was easily enucleated, and the surgical specimen exhibited numerous tooth-like structures. Radiographic imaging at the 6-month follow-up demonstrated evidence of osseous regeneration of the surgical site.

A survey examined the demographics, practice characteristics, service mix, and barriers faced by non-orthodontists in the provision of orthodontic care to the pediatric population, including children enrolled in Medicaid programs. Respondents reported multiple challenges, particularly for the Medicaid population, underscoring the need for reforms to address financial and administrative barriers to orthodontic care.

This in vitro study aimed to compare the effects of conventional and ultrasonic root canal preparation on the adhesion of glass fiber posts to dentin. In push-out testing, the conventional group exhibited significantly lower bond strengths than the ultrasonic group across all anatomical thirds (cervical, middle, and apical). The groups showed no significant differences in failure modes.

This review summarizes the advantages and disadvantages of AI systems in orthodontic treatment planning. AI can perform automated functions, allowing clinicians to more effectively use their time making critical diagnostic, treatment, and care decisions. However, clinicians must be aware of the limitations of AI, including ethnic biases in algorithms or datasets and possible ethical challenges.

A survey with different case scenarios was designed to assess differences among general dentists, pediatric dentists, and orthodontists in perceived treatment need for transverse maxillary expansion. The findings suggest that specialty training strongly influences decisions, highlighting a need for enhanced orthodontic diagnostic education to promote consistency in the diagnosis and management of transverse discrepancies.
