Dystrophic calcification vs sialolithiasis in a pediactric parotid gland: A case report.

Calcinosis is a connective tissue disorder characterized by ectopic calcification in soft tissues. It is subdivided into: dystrophic, metastatic, idiopathic and iatrogenic calcification. The formation of mineralized material in the salivary glands is a common finding in the daily practice of dentists and other specialists. In most cases, this calcification is a sialolith. However, a type of ectopic calcification termed dystrophic calcification is characterized by inappropriate biomineralization in soft tissues and may be associated with trauma, chronic and localized infection or inflammatory diseases. We report a case of a 9-year-old female patient who complained of small nodules in the left parotid region, which begun two years before. Her main complaint was of recurring periods of worsened symptoms characterized by the exacerbation and symptomatic remission of the gland volume with occasional otolaryngologic infections. This study aims to discuss ectopic dystrophic calcification in the parotid gland associated with recurrent infection in children. Key words:Dystrophic calcification, salivary gland, pediatric pathology.

Reconstruction and Mandibular Rehabilitation After Resection of Juvenile Aggressive Ossifying Fibroma Using Undifferentiated Mesenchymal Cells and Osseointegrated Implants: A Case Report.

PURPOSE: The aggressive juvenile ossifying fibroma is a benign fibro-osseous neoplasm that affects the jaws of young patients. The treatment can range from careful curettage to complete bone resection. Early dental rehabilitation through osseointegrated implants is indicated for functional recovery and esthetics. MATERIALS AND METHODS: This article reports the case of a 20-year-old man submitted to osseous resection, installation of a titanium plate associated with bone graft and osteogenic substances with subsequent installation of osseointegrated dental implants. RESULTS: After 28 months of clinical and radiographic follow-up, there were no signs of tumor recurrence. As the patient showed good graft integration, 3 dental implants could be installed and are now waiting to receive a prosthetic work. CONCLUSIONS: The use of a graft with morphogenetic proteins proved to be stable and efficient as it allowed the rehabilitation with dental implants.
