The present study was performed to compare the amount of in vitro fluoride uptake by enamel and dentin from fluoridated bonding agent with non-fluoridated composite (Group I), non-fluoridated bonding agent with fluoridated composite (Group II) and fluoridated bonding agent with fluoridated composite resin (Group III). Sixty extracted premolars were selected and divided into three groups of 20 teeth each. Restorative materials were applied according to manufacturer's instructions into standard windows created in the teeth, cured and placed in de-ionised water for three months. The fluoride content of successive acid etch biopsy was determined by specific ion-electrode analysis. Although significant amount of fluoride uptake occurred in all the test groups, fluoride uptake was found to be highly significant in dentin when compared to enamel in Group, I, II and III (P<0.001). The fluoride uptake was greater by both enamel and dentin in Group III ie fluoridated bonding agent with fluoridated composite resin.

The management of two cases of hypertaurodontism, is presented. The first case shows this uncommon dental anomaly in all the four permanent first molars. The second case is concerned with endodontic management of a hypertaurodontic mandibular second premolar. The authors wish to highlight the importance of careful radiographic examination in diagnosing this rare dental anomaly in view of the difficulties encountered in performing endodontic treatment.

The phosphorus concentration and alkaline phosphatase activity in saliva may be related to the susceptibility to dental caries. Thirty children in the age group of 4-6 years were divided into 3 groups. Group 1, children had rampant caries with dfs>10, group 2- dfs>5<10, group 3 caries free with dfs<1. The unstimulated mixed salivary sample was collected from each child and assayed by biochemical methods to determine the phosphorus and alkaline phosphatase concentration in saliva sample. The results showed that higher alkaline phosphatase activity and phosphorus concentration were associated with rampant caries.

This article presents a case report of radicular cyst associated with an endodontically treated deciduous second molar causing displacement of the permanent successor, with accompanying buccal expansion. Cystic sac was removed surgically along with the involved tooth under general anesthesia. Healing was uneventful. Histopathologically the cystic sac was consistent with the features of radicular cyst. Unusual amorphous, eosinophilic, atubular material incorporated within the cystic epithelium was observed.

Comprehensive dental care for 150 blind school children was carried out. The main goal of this oral hygiene programme was to create awareness to enable them to be independent in their oral hygiene care.

Actinomycosis often referred to, as the chameleon of the head and neck pathology is a rare disease, uncommon in children. This article refers to a case of intraoral actinomycotic lesion of the palate in a child following a rare aetiology, the relevant literature, clinical course and its successful resolution.

The purpose of this study was to know the prevalence and pattern of dental health problems in rural school children of Kerala and to identify the priority area for dental health education programmes. The children were examined and findings recorded. the findings show that more than 50% of the children in the 12 to 15 years of age group in rural Kerala suffers from some form of dental diseases. Males and females are equally affected and dental caries is the most common problem encountered.

An interesting lesion is presented, wherein a tiny traumatic perforation of the buccal mucosa and buccinator muscle forced a large portion of the buccal fat pad to extrude into the oral cavity. Such a situation can alarm any clinician & reinforces the importance of careful history taking and thorough examination, before treating patients.
