8/6/2023 0 Comments Lingual calculus bridge![]() ![]() In the early 17 th century, Pierre Fauchard in his classic treatise “Le Chirugren Dentiste” reported a completely submerged molar tooth in a large piece of calculus, of 20 times the size of the molar itself. Dental calculus does not contribute directly to gingival inflammation, but it provides nidus for the continued accumulation of plaque. Several reasons have been proposed such as increase in pH of saliva and precipitation of colloidal proteins in saliva and seeding agent inducing the foci of calcification. The main source of mineralization is from saliva. This case report reveals an unusual presentation of dental calculus in the left side of retromolar region associated with a partially erupted left mandibular third molar tooth.ĭental calculus is a calcified dental plaque, which usually occurs between 1 and 14 days of plaque formation, usually reaching 60%–90% of calcification by 12 days. In spite of these regular places, calculus can be presented in an unusual location of the oral cavity where maintenance is very difficult. The areas to exhibit calculus deposits were the facial aspect of maxillary molars and lingual surface of mandibular teeth. It is usually seen in young age and continues to be deposited till 25–30 years where they exhibit maximal deposition. Usually, the formation of dental calculus is mainly by mineral precipitation from a local rise in the degree of saturation of calcium and phosphate ions and also due to inducing of seeding agents to form small foci for calcification of dental plaque. It is usually typically dark-brown or green or black and dense in consistency. Supragingival calculus is whitish yellow and is usually clay-like in consistency, whereas subgingival calculus is not visible clinically but can be evaluated by tactile sensation. ![]() It can be seen either supragingival or subgingival, and it is mainly composed of 80%–85% of inorganic content. It consists of mineralized dental plaque that forms on the natural teeth and dental prosthesis. Calculus is a calcified mass, most commonly seen in areas where the salivary duct opens into the oral cavity. ![]()
