It is inherited in an autosomal dominant pattern, as a result of mutations on chromosome 4q21, in the dentine sialophosphoprotein gene (DSPP). [1][2][3][4][5] It is one of the most frequently occurring autosomal dominant features in humans. [6]

Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion.) Tooth formation begins before birth, and the teeth's eventual morphology is dictated ...
Humans have four types of teeth: incisors, canines, premolars, and molars, which each have a specific function. The incisors cut the food, the canines tear the food and the molars and premolars crush the food. The roots of teeth are embedded in the maxilla (upper jaw) or the mandible (lower jaw) and are covered by gums.
Disclosing tablets are chewable tablets that make dental plaque visible. The tablets, sold over the counter in many countries, contain a dye (typically a vegetable dye, such as Phloxine B) that stains the plaque a bright color (typically red or blue). After brushing, one chews a tablet and rinses. Colored stains on the teeth indicate areas ...
