  2. Calculus is a bacterial plaque that has been mineralized.Itis a deposit of calcium phosphate salts. It has variety of appearance on dental radiograph. The bitewing shows subgingival calculus which is visible as cervical spurs upon the proximal tooth surface in the posterior segments, on the maxillary and mandible first and second molars.

  3. Calculus may appear as a ring-like radiopacity around the root of mandibular teeth

  4. Diabetes mellitus can cause dysfunction of the secretory ability of the salivary gland. Diabetic patient have an increased salivary calcium phosphates and protein concentration compared to non-diabetic. Here we can see large mass of dental calculus that is covering the surface of two remaining teeth.

  5. Calculus may appear nodular, as seen here on the distal side of the third molar, beneath the crown margin.

  6. Ledge-like calculus on the mandibular lateral incisors.

  7. Salivary calculus ( Sialolithiasis) is a salivary duct obstruction. It can be caused by trauma or local inflammation, chronic disease ,infection. Dental radiograph of the sublingual space reveals the size and location of the salivary calculus

  8. Subgingival calculus appears as irregular radiopaque projections on the maxillary incisors.

  9. Ring-like calculus (radiopaque line) on mandibular canine and first premolar.
