Duration of treatment is one of the main concerns of patients undergoing orthodontic treatment. Fixed orthodontic treatment lasts up to 2 to 3 years increasing the risk of external root resorption, periodontal problems and patient compliance [1]. Clinicians are constantly striving towards developing strategies to enhance the rate of orthodontic tooth movement. An increase in in-depth knowledge ...

Reptiles and fish have robust regenerative powers for tooth renewal. However, extant mammals can either renew their teeth one time (diphyodont dentition) or not at all (monophyodont dentition). Humans replace their milk teeth with permanent teeth and then lose their ability for tooth renewal. Here, we study tooth renewal in a crocodilian model, the American alligator, which has well-organized t...

AIM There is limited scientific information on the relationship between tooth shade, age, gender, and skin color in black Africans. This lack of knowledge may impact the ability of the prosthodontist to select artificial teeth for completely edentulous patients. This study explores the possibility of a relationship between tooth shade, gender, age, and skin color in a black African population. ...

In order to test whether the formation of a replacement tooth bud in a continuously replacing dentition is linked to the functional state of the tooth predecessor, I examined the timing of development of replacement teeth with respect to their functional predecessors in the pharyngeal dentition of the zebrafish. Observations based on serial semithin sections of ten specimens, ranging in age fro...

considerations and assumptions Scientifically, the following questions have not been accurately answered yet: 1. What determines tooth color, its shades and hues and its variations even in the same person? 2. Does tooth color result from the distribution of a pigment at variable concentrations in tooth structure? 3. Is color a consequence of the level of mineralization of tooth tissues, their t...

The purpose of this study was to evaluate cuspal flexure in posterior primary teeth following restoration with three different materials. Twelve primary second molars were obtained. A precision strain gage was attached to the buccal surface of each tooth and balanced at zero. The teeth were mounted and then loaded with a 10 kg force; the strain appearing on the strain gage indicator was recorde...

dental trauma generally requires multidisciplinary planning and treatment for good prognosis. when immature teeth are traumatized to a degree where pulp necrosis ensues, the objective of root canal treatment should be apexogenesis and root maturation. apexification of the root is the conventional choice, which involves cleaning the canal and filling it with a temporary medication that stimulate...
