Myositis Ossificans Traumatica, an Unusual Cause of Mandibular Hypomobility.

ABSTRACT: Myositis ossificans traumatica is a rare condition in which causes restriction of mandibular movement. In this entity, temporomandibular joint is depleted of any problems; although all the patients have the history of trauma to the mandible and the face. Myositis ossificans traumatica can involve other parts of the body like femoral region with higher incidence in compare to the maxillofacial area. Blunt trauma to the head and neck causes muscle contusion injury, hematoma formation in the injured muscles or nearby soft tissues. Calcification of hematoma and heterotopic bone formation in the muscle, soft tissue, or near bony structures causes progressive decrease in mouth opening. Surgical removal of calcified body has been the only and one method for treatment of this disorder but rate of recurrence is high in the literature. The authors want to introduce 2 new cases of myositis ossificans traumatica, and then discuss about etiology and different treatment modalities.

Candida Colonization on the Denture of Diabetic and Non-diabetic Patients.

BACKGROUND: Oral candidiasis is a common opportunistic infection in diabetic patients. Presence of denture in the oral cavity of diabetic patients can promote Candida colonization and results in the higher incidence of oral and systemic candidiasis. The general purpose of the present study was to evaluate and compare Candida colonization in denture of diabetic patients and non-diabetic control group. METHODS: In current case-control study, samples for mycological examinations were collected from the palatal impression surface of maxillary dentures from 92 edentulous patients including 46 dia-betic and 46 non-diabetic denture wearers. All samples were cultured directly on sabouraud agar me-dium and isolated colonies were counted and identified based on specific tests. Data were statistically analyzed using Mann-Whitney and Spearman correlation tests. RESULTS: The higher density of isolated colonies was seen in diabetic group in compare with control group (P = 0.0001). There was a statistically significant correlation between the blood glucose level (P = 0.0001) and the duration of denture usage (P = 0.022) with the colonization of Candida on denture of diabetic patients. C. albicans was the most common isolated Candida species in both groups, though diabetic patients with dentures had more non-albicans Candida isolated from their dentures compared to non-diabetic patients. CONCLUSIONS: Mycological findings from the present study revealed that diabetes mellitus can in-crease colonization of Candida in denture and mouth. By elimination of local and systemic factors in diabetic patients and improving their oral health care, Candida colonization and the risk of oral and systemic candidiasis will be decreased.
