Abstract
Inadequate oral hygiene is the root cause of the initiation and establishment of the periodontal disease. Dental calculus serves as plaque retentive area, thereby contributing to gingivitis and periodontitis. The present unusual case is of a 55-year-old female patient reported to the department of periodontology with a chief complaint of hard deposit at the right maxillary and mandibular posterior region. The patient was found to have very heavy calculus deposition with respect to right maxillary and mandibular posterior teeth, and the patient was using the left side for mastication and avoiding chewing from the right side mainly due to some periodontal problem. The extraction of the hopeless teeth along with dental calculus was done. Dimensions of dental calculi at maxillary and mandibular teeth was 4 cm × 3 cm each.
