DentalSegmentator: Robust open source deep learning-based CT and CBCT image segmentation.

Objectives: Segmentation of anatomical structures on dento-maxillo-facial (DMF) computed tomography (CT) or cone beam computed tomography (CBCT) scans is increasingly needed in digital dentistry. The main aim of this research was to propose and evaluate a novel open source tool called DentalSegmentator for fully automatic segmentation of five anatomical structures on DMF CT and CBCT scans: maxilla/upper skull, mandible, upper teeth, lower teeth, and the mandibular canal.

Methods: A retrospective sample of 470 CT and CBCT scans was used as a training/validation set.

Comparative effect of anthocyanin on proliferation and migration of human gingival fibroblasts in the absence or presence of nicotine.

Background: Oral fibroblast malfunction can result in periodontal diseases. Nicotine can prolong the healing process as an irritant of oral tissues. Anthocyanins have been demonstrated to have potential benefits in preventing or treating smoking-related periodontal diseases.

Clinical and Radiographic Assessments of Tooth Socket Preservation Using Leukocyte Platelet-Rich Fibrin.

Leukocyte platelet-rich fibrin (L-PRF) has the potential to accelerate wound healing. Here, we assess clinical and radiographic outcomes of socket preservation using L-PRF. For this single-blind, randomized, split-mouth clinical trial, we selected 22 patients (15 males and seven females), who required extraction of single-rooted teeth.
