Purpose: Furcation involvement in the molars is difficult to treat, and has been recognized as a risk factor for tooth loss. Although periodontal regenerative therapies, including guided tissue regeneration and various types of bone grafts, have been applied to furcation defects, the effects of these treatments are limited, especially in large class III furcation defects. The purpose of this pilot study was to investigate the effect of reciprocal autologous root transplantation on periodontal wound healing and regeneration in class III furcation defects in dogs...

Background: Guidelines for antibiotics prior to dental procedures for patients with specific cardiac conditions and prosthetic joints have changed, reducing indications for antibiotic prophylaxis. In addition to guidelines focused on patient comorbidities, systematic reviews specific to dental extractions and implants support preprocedure antibiotics for all patients. However, data on dentist adherence to these recommendations are scarce. Methods: This was a cross-sectional study of veterans undergoing tooth extractions, dental implants, and periodontal procedures...

INTRODUCTION: Severely impacted teeth with atypical root anatomy do not respond well to orthodontic traction after surgical exposure. Consequently, they are often removed, but replacing them with dental prostheses can prove difficult in patients who are still growing. Thus, autotransplantation seems to be the only way to preserve a natural tooth and the alveolar bone. MATERIALS AND METHODS: An upper central incisor impacted in the region of the nasal cavities with an open apex was diagnosed in an 8...

OBJECTIVE: Numerous studies on alveolar bone augmentation have been reported. However, it remains challenging to obtain favorable new bone, especially for onlay bone augmentation. For successful onlay bone augmentation, it is necessary to use a graft material with high bone-forming activity and wound stabilization. We performed onlay bone augmentation on the buccal surface of mandibular alveolar bone in dogs, using a polyethylene terephthalate (PET) case (Casing method). The aim of this study was to histologically examine the feasibility of Casing method for external onlay bone augmentation...

INTRODUCTION: Alveolar bone is critical in supporting natural teeth, dental implants as well as a removable and fixed prosthesis. Alveolar bone volume diminishes when its associated natural tooth is lost. OBJECTIVE: The aim of this study is to evaluate the effectiveness of bovine bone granules on alveolar bone socket augmentation for ridge preservation following atraumatic tooth extraction. MATERIALS AND METHODS: Twenty medically fit patients (12 males and 8 females aged between 18 and 40 years) who needed noncomplicated tooth extraction of 1 mandibular premolar tooth were divided randomly and equally into 2 groups...

Background: In this study, we present a case of unicystic ameloblastoma (UA) treated by marsupialization followed by surgical enucleation as a conservative approach. UA is a rare, benign, less aggressive, and less invasive variant of ameloblastoma that is observed quite often in younger patients. Radical approaches have effects on the physical and psychological development of a growing young patient; therefore, conservative approaches are widely used for UA management in children. Case presentation: This report described a case of an 11-year-old girl with UA of the mandibular molar-ramus area, which also involved impaction of the second and third molars...

One of the major challenges of molecular biology in anthropological analysis is the identification via DNA typing of bone or teeth samples that can be collected from archaeological site in order to investigate kinship relationships. Due to the difficulties of isolating and analysing DNA from such samples, several efforts have been made to solve these problems, but less work has been conducted to identify the proper type of bone samples for the DNA analysis. Therefore, following the promising results obtained from the DNA analysis of petrous bones by different groups of researchers, for the first time, here we investigated the possibility of using petrous bones as skeletal elements useful for short tandem repeat (STR) typing via capillary electrophoresis technique in ancient bone samples...
