Hence, the presence of calculus in this site correlates with McGaughey et al., who proposed that calcium and potassium formation in calculus is due to the protein bond in saliva. The deposition near the floor of the mouth supports the fact that saliva from submandibular gland shall have provided the inorganic content for calculus formation. The unusual amount of formation of calculus seen in this patient goes well beyond the classification of heavy calculus formation as reported by Mandel. In this case report, the patient had a myth that the deposition was related to some other lesion and also was hesitant to meet the dentist until he felt difficulty in closing his mouth. This is a rare phenomenon to be seen today with our ever-changing lifestyles, with the availability of top-notch dental care systems, highly effective oral hygiene products besides dignity in oral cleanliness, and personal pride. Only in ancient times, such types of massive and unusual deposition of calculus have been reported in dentistry. 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.
