An unprecedented case is presented involving a massive calculus buildup on the mandibular incisors. The clinical and radiographic findings were reviewed, probable causes were investigated, and results were outlined and discussed. The composition, origin, and formation of dental calculus and its interrelationship with dental plaque and saliva were highlighted. The role of dental calculus in the pathogenicity of periodontal diseases, in view of epidemiological data, research, and clinical study findings, is discussed. Both the case management and the benefit of total calculus removal for resolving periodontal disease are underlined.
