Myiasis is the condition of infestation of the body by fly larvae (maggots). The deposited eggs develop into larvae, which penetrate deep structures causing adjacent tissue destruction. It is an uncommon clinical condition, being more frequent in tropical countries and hot climate regions, and associated with poor hygiene, suppurative oral lesions, alcoholism and senility. The diagnosis of Myiasis is basically made by the presence of larvae. The reported cases of oral Myiasis associated with oral cancer in the literature are few. This paper reports two cases of oral and maxillofacial Myiasis involving larvae in patients with squamous cell carcinoma in adult males. The condition was managed by manual removal of the larvae, one by one, with the help of forceps and subsequent management through proper health care.

Objectives. The objective of this in vitro study was to investigate whether weight gain or loss in the three different composites occurs due to water absorption when they are stored in water.Methods. The composite restorative materials selected for this study included a microfine hybrid (Synergy) and two nanofilled composite restorative materials (Ceram X and Filtek Supreme Ultra). Twenty specimens of each material were fabricated of each composite material. Group A: Filtek Supreme Ultra, Group B: Synergy, Group C: Ceram X. Then all the specimens were stored in 10 ml Distilled water containing test tubes and placed in incubator at 37°C for six weeks. The weight changes of these specimens were measured daily for the first week and later once a week for next five weeks by using an electrical analytical balance.Results.The data was analyzed by one-way analysis of variance and Student'sttest. All groups showed maximum amount of water absorption in the first week than gradual decrease in the water absorption from the second to the sixth week, as compared to the first week and there is no statistically significant difference between the groups tested.Conclusion. All the composite restorative material absorbs some amount of water. The water absorption of the composite may decrease the physical and mechanical properties of the composites; hence it is necessary to consider the type of the material before starting the treatment.

The correlation of clinical and histopathological staging was found to be highly significant, thus suggesting that the subject with clinically advanced OSF had extensive fibrosis histologically.

Osteoradionecrosis (ORN) defines exposed irradiated bone, which fails to heal over a period of 3-6 months without evidence of residual or recurrent tumor. It is a long term and serious complication of therapeutic radiotherapy for head and neck cancer. The pathogenesis of ORN has been proposed relating it to a fibroatrophic mechanism including free radical formation, endothelial dysfunction, inflammation, microvascular thrombosis leading to bone and tissue necrosis. Risk factors mainly include radiation related risk factors, surgery, tobacco and alcohol abuse. Removing of diseased teeth after radiotherapy is generally considered the main risk factor in ORN. Prevention of ORN is based on the preventive extractions of decayed or periodontally compromised teeth before radiotherapy. Based on the clinical staging various therapeutic protocols have been suggested. We here report a case of Bilateral mandibular ORN with discussion of clinical features, pathogenesis, preventive measures, and management of ORN.
