Orthodontics in combination with orthognathic surgery is a possibility today for correcting sagittal, vertical and transversal dysmorphosis. To do this, orthodontic preparation before surgery is necessary. In the sagittal plane, dental compensations should be removed. In the vertical plane, levelling of a severe mandibular SPEE curve should be accomplished postsurgically, and transverse coordination obtained. Orthodontic preparation is very specific to the type of dysmorphosis: class II malocclusion, class III malocclusion or in open bite. Postsurgical orthodontic treatment is used to finalize tooth alignment as in conventional orthodontics.

Background: Survival rate of patients with oral cancer (OC) remains to be very low despite advancements in therapy and surgical techniques. This is attributed to the fact that most OC cases are discovered at a late stage. Dentists play a vital role in early detection of OC through oral mucosal examination, and in informing the patients about avoidable risk factors of the disease, such as tobacco and excessive alcohol use.

Periodontal disease is a major contributor to tooth loss worldwide in adults. Particularly, periodontal bone defect is a common clinical condition, yet current therapeutic strategies exhibit limited effectiveness. Recently, natural bone graft materials have attracted considerable interest for enhancing bone defect repair due to their superior biocompatibility and osteogenic capabilities.

Background The thyroid gland is the most susceptible organ to radiation during the exposure of teeth because the thyroid area appears to be within the primary beam, and the dose levels are relatively high even after using collimation. This study aims to develop an eco-friendly thyroid shield by reusing lead foils from intra-oral periapical radiographic films and evaluate its effectiveness in intraoral radiography. Methods A total of 16 patients undergoing endodontic procedures who gave written consent to participate in the study were included and divided into four categories: anterior, canine, premolar, and molar.

Objectives: This study aimed to compare the marginal adaptation of a cold ceramic (CC) sealer with the single-cone obturation technique with that of an AH-26 sealer with the lateral compaction technique in single-canal teeth.
Materials And Methods: In this in vitro experimental study, the root canals of 24 extracted single-rooted single-canal teeth were instrumented to F3 files by the crown-down technique and randomly assigned to 2 groups (n = 12). The root canals were obturated with a CC sealer and single-cone obturation technique with 4% gutta-percha in group 1 and with an AH-26 sealer and lateral compaction technique with 2% gutta-percha in group 2.
