Betel chewing and dental decay.

A survey was carried out on Four hundred and sixty patients to find out the effects of betel chewing on dental caries & oral hygiene. It was found that among the betel chewers as well as the non betels chewers., the highest caries susceptibility was in the age group of 20-34 years. Also caries susceptibility was higher among the females as compared to males. It was also observed that though the habit of betel chewing reduces the incidence of dental decay, maintenance of oral hygiene is very poor.

Comparative evaluation of marginal leakage of different types of silver amalgam alloys in vitro--a microfluoroscopic study.

A study was carried out in vitro to evaluate the amount of microleakage using seven different Silver amalgam alloy using Fluorescein dye. Among the high copper alloy used in this study, the admixed alloy showed least marginal leakage followed by the high copper lathecut alloy and the high copper spherical alloy. It was also observed that the marginal penetration of the conventional alloy are much more than the high copper alloy.

Primary tumours and tumour-like conditions of the mandible.

Reports on comprehensive mandibular tumours are very rare. The present article describes a total of 81 primary tumour and tumour-like lesions of the mandible seen at the University Hospital, Banaras Hindu University, during last 16 years. In the mandible the ratio of odontogenic to nonodontogenic tumors is 1.6:1. Ameloblastomas constitute 56% of the odontogenic tumors. Among the benign mesenchymal tumours of the jaw 58% are neoplastic and 42% are nonneoplastic in which cementoostoid tissue is laid down secondary to inflammatory process. Over all 40 cases are benign 28 potentially malignant (ameloblastoma) and 13 are malignant lesions. Among the malignant mandibular tumours, bone tumours are more common than the soft tissue sarcomas. Microscopically mandibular osteosarcomas are better differentiated than similar tumours in the long bones. Local, segmental, or radical surgery seems to be the treatment of choice in the mandibular tumours.

Temporomandibular ankylosis.

Temporomandibular ankylosis is commonly seen in children and young adults. Trauma in childhood is the commonest cause. Treatment of choice is by surgical intervention. Depending upon the local findings a gap arthroplasty or interposition arthroplasty is the procedure carried out. Early mobilisation is recommended.
