wisdom tooth operations are sometimes accompanied by complications. this case report shows complications during upper jaw third molar removal. expectable problems during oral surgery should be planned to be solved in advance. displacement of the third molar during oral surgeries as a considerable complication is rarely discussed scientifically. a good design of flap, adequate power for extracti...

OBJECTIVE To determine the relationship of tooth form with the face form by different observers and further investigate the inter observer agreement on tooth forms, face forms, their relationship among male Saudis. STUDY DESIGN A comparative cross-sectional study. PLACE AND DURATION OF STUDY Department of Prosthodontics, College of Dentistry, King Saud University, Riyadh, KSA, from February...

OBJECTIVE To verify the incidence of tooth loss in extended age group of adults in 4 years. MATERIALS AND METHODS The prospective cohort study assessed adults (20-64 years old) between 2011 and 2015, from Piracicaba, São Paulo, Brazil. The dependent variable was cumulative incidence of tooth loss, assessed by difference between missing teeth (M) of decayed, missing, and filled tooth index (DM...

INTRODUCTION Recently, several reviews have been published on the effects of medications on bone physiology and the clinical side effects in orthodontics. However, the effects of medications on the rate of orthodontic tooth movement have not been evaluated. METHODS A systematic literature review on the effects of medications and dietary supplements on the rate of experimental tooth movement w...

Tooth renewal is initiated from epithelium associated with existing teeth. The development of new teeth requires dental epithelial cells that have competence for tooth formation, but specific marker genes for these cells have not been identified. Here, we analyzed expression patterns of the transcription factor Sox2 in two different modes of successional tooth formation: tooth replacement and s...

Teeth are a classicmodel system of organogenesis, as repeated and reciprocal epithelial and mesenchymal interactions pattern placode formation and outgrowth. Less is known about the developmental and genetic bases of tooth formation and replacement in polyphyodonts, which are vertebrates with continual tooth replacement. Here, we leverage natural variation in the threespine stickleback fish Gas...

OBJECTIVE To compare clinical results of three types of manual tooth brushes on plaque removal efficacy and gingivitis. METHOD This study is a single blind randomized trial with crossover design which involved 30 periodontaly healthy individuals. Professional plaque removal and oral hygiene instruction were performed for all the participants in the first step of our study followed by asking t...

Nowadays, there is an increased tendency for researches to focus on accelerating methods for tooth movement due to the huge demand for adults for a shorter orthodontic treatment time. Unfortunately, long orthodontic treatment time poses several disadvantages like higher predisposition to caries, gingival recession, and root resorption. This increases the demand to find the best method to increa...

In order to derive the equation of the contact line of the involute curvilinear-tooth cylindrical gear pump for the agricultural tractor, the tooth surface of the involute curvilinear-tooth cylindrical gear is firstly generated as that of the spur or helical gear. Then the equation of the tooth surface is derived from changing the settings and orientations of the coordinate systems after the eq...
