Titanium has gained immense popularity and has successfully established itself as the material of choice for dental implants. In both medical and dental fields, titanium and its alloys have demonstrated success as biomedical devices. Owing to its high resistance to corrosion in a physiological environment and the excellent biocompatibility that gives it a passive, stable oxide film, titanium is considered the material of choice for intraosseous use. There are certain studies which show titanium as an allergen but the resources to diagnose titanium sensivity are very limited. Attention is needed towards the development of new and precise method for early diagnosis of titanium allergy and also to find out the alternative biomaterial which can be used in place of titanium. A review of available articles from the Medline and PubMed database was done to find literature available regarding titanium allergy, its diagnosis and new alternative material for titanium.

Background:In head and neck cancer patients undergoing radiotherapy, osteoradionecrosis (ORN) of the jaw is one of the major but uncommon complications. Satisfactorily results have been observed while treating ORN patients with upcoming treatment modalities such as combination therapy of pentoxifylline and Vitamin E (PVe). It is believed that in patients undergoing dental extractions, these treatment modalities can be used prophylactically for lowering the risk of development of ORN. Hence, keeping all these things in mind, we planned the present study to assess the prophylactic role of pentoxifylline and tocopherol in patients who require dental extractions after radiotherapy for cancer of head and neck.Materials and Methods:A total of 110 patients were included in this retrospective study, which had radiotherapy for cancer of the head and neck. After radiotherapy, a total of 450 dental extractions were done in these 110 patients.Results:External beam therapy was given in 92.72% of the patients. 7.27% and 40% of the patients received intensity modulated radiotherapy combination of chemotherapy and intensity modulated radiotherapy, respectively. ORN developed only in 2 patients. Patients had taken PVe for a mean of 12 (24) weeks preoperatively and 14 (18) weeks postoperatively. The incidence was lower than that normally associated with dental extractions in irradiated patients.Conclusion:In patients undergoing dental extractions, after receiving radiotherapy of head and neck region, combination therapy of pentoxifylline and tocopherol are sufficiently effective.

Special attention should be paid to the pediatric patients with such kind of behavior so that their psy-chosocial attitude could be modified in favor of dental treatment.

The positive psychological effects of improving patients' smile often contribute to an improved self-image and enhanced self-esteem. Periodontal disease may lead to tooth and tissue loss that can result in esthetic problems. Combined periodontal/prosthodontic treatment for patients with advanced disease is well documented. This case report illustrates a method of treatment for an advanced tissue loss in an esthetic area using a removable silicone gingival prosthesis/mask.
