The aim of this case report and in vitro investigation was to evaluate the marginal microleakage of intact occlusal calculus of primary molars extracted from a special needs patient who received nutrition via a gastric feeding tube. An adolescent with a history of developmental disturbance presented for routine dental care in a hospital facility. Prophylaxis was performed, and 2 mandibular permanent molars were restored. Five primary molars were extracted due to mobility and delayed retention. Heavy deposits of intact calculus were present on the occlusal surfaces of the primary teeth. The extracted teeth were immersed in methylene blue dye solution, invested in acrylic resin, sectioned into blocks, and photographed at 20× and 40× magnification. Previously photographed calculus-free molars with pit and fissure sealants were reviewed and served as contrasting "restorations." The occlusal calculus on the primary teeth extracted from the patient absorbed the dye, while the comparison teeth containing pit and fissure sealants exhibited varying degrees of marginal dye penetration (microleakage). No marginal microleakage was noted in the calculus specimens, indicating that this substrate may serve as a "natural" occlusal surface sealant and that its removal from occlusal surfaces during routine oral prophylaxis may be unnecessary.

A variety of systemic drugs can lead to adverse effects in the oral environment. This article reports the case of a 61-year-old man who had a severe drug-induced gingival overgrowth (DIGO) caused by nifedipine. DIGO is relevant due to severe gingival enlargement, which causes disfigurement and blocks physiological and social functions such as mastication and speaking. Management of DIGO is always a challenge due to the patient's systemic condition. This article shows, step-by-step, how the treatment was executed and how the DIGO was reversed.

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.

The peripheral giant cell granuloma is a reactive lesion of the soft tissue of the oral cavity. Clinical appearance ranges from normal tissue coloration to dark red or purplish. These are elevated lesions generally 5-15 mm in diameter. Etiology is considered to be chronic irritation. To decrease the risk of clinical recurrence, treatment is complete excision to include the underlying periosteum. Histologic features of the peripheral giant cell granuloma include multinucleated giant cells with a stroma that may contain osteoblasts, myofibroblasts, macrophages, and Langerhans cells. A case report is presented.
