Purpose: To study the heritable character and explore the prosthodontic treatment of opalescent dentin, also known as dentinogenesis imperfecta type II(DGI-II).
Methods: Pedigree analysis was performed in the family members of patients with DGI-II found in Shanghai. The proband was treated with ceramometal restorations and investigated the treatment status of the DGI-II affected individuals in the family.
Results: Five sequential generations with DGI-II were found in this family. The prevalence of later generation was approximately 50%. The rate of prosthodontic treatment was 90% nearly, including ceramometal restorations in the most of the patients and removable partial dentures in the others. The esthetic and mastication functions of the patients were good after treatment.
Conclusions: DGI-II showed a autosomal dominant pattern of inheritance. Ceramaometal restorations can prevent the affected teeth from abrasive and fracture, and also can help rehabilitate the esthetic and mastication functions of the teeth.

Background: The treatment procedure for intracapsular condylar fractures (ICF) is still being debated. The temporomandibular joint (TMJ) disc is a key factor for treating ICF. The study aims to investigate the changes in TMJ disc status and condylar cartilage regeneration following ICF in a rabbit model, to assist in planning treatment.

Private Practice, Brooklyn, NY, USA.
Complete arch oral implant treatment using photogrammetry was studied in 77 patients with 111 arches focusing on digitization of clinical records and optimization of the provisional. The aim of the study was to test the hypothesis that patient satisfaction with the provisional prosthesis during the first 4 months of care determined workflow efficiency and success. Digitization of 8 clinical records was done including centric relation, vertical dimension, esthetics, occlusion, inter-arch space, abutment selection, abutment capture, and soft tissue scan.

Faculty of Dentistry, Department of Restorative Dentistry, Eskisehir Osmangazi University, Eskisehir, Turkey.
Objective: To evaluate the 36-month clinical performance of Single Bond Universal Adhesive (SBU; 3M ESPE, Germany) in non-carious cervical lesions (NCCLs) using different modes of adhesion according to the FDI criteria. The primary outcome was the retention loss of the restorations, while the secondary outcomes included marginal staining, marginal adaptation, post-operative sensitivity and tooth vitality, recurrence of caries erosion and abfraction, and tooth integrity, all evaluated according to the FDI criteria.
Materials And Methods: In this study, the SBU Adhesive was applied to 246 NCCLs of 25 patients using different modes of adhesion: Self-etch (SE), selective-enamel-etching (SLE), and etch-and-rinse (ER).
Unveiling the mechanical performance of partially replaced coronal restorations in root canal-treated teeth: an in-vitro study.
BMC Oral Health
December 2024
Department of Conservative Dentistry, Faculty of Dentistry, Minia University, Minia, Egypt.
Objectives: To compare the mechanical performance of partially replaced (repaired) intra-coronal restorations to totally replaced ones in root canal-treated teeth.
Methods: Thirty maxillary second premolars were selected according to strict criteria, mounted on moulds, and had mesio-occluso-distal (MOD) cavities prepared. Resin composite restorative material was used to perform the initial restoration, followed by aging procedures using thermo-mechanical cycling fatigue to replicate six months of intraoral aging.

Placing an implant immediately into extraction sockets provides a distinct advantage over delayed placement, eliminating the need for a 4 to 6 months waiting period for bone formation. However, when patients present with hypothyroidism, the feasibility of immediate placement of dental implants becomes uncertain. This case involved a hypothyroid woman in her late 60s with loose lower anterior teeth.
