The present study was carried out to evaluate the Al, F, Na and Sr release profiles of conventional and resin modified glass polyalkenoate cements in neutral (deionized water) and acidic medium (lactic acid). Twelve pellets of each material were prepared under standardised conditions and were immersed in their respective solutions for a study period of 90 days. Fluoride analysis was carried out by Orion Electrode and the other elemental analysis were done by Atomic Absorption Spectrophotometer. Statistical analysis revealed no significant difference in the Al, F and Na release profiles between the two materials in both neutral and acidic media.

A three year old female child was brought to the Department of Pedodontics, Dental College, Thiruvananthapuram with a greyish white papillomatous lesion involving a large area on the buccal mucosa. VDRL was positive for the little girl as well as her father and was positive in low concentrations for her one-month-old sister as well as her mother.

A study was conducted using dermatoglyphics to predict and compare Class I, Class II, div. 1, div.2 and Class III malocclusions. A total of 96 subjects were divided into 3 malocclusion groups, i.e. Class I (control group), Class II, div.1, div.2 and Class III (experimental group) in the ages of 12-14 years. The dermatoglyphic findings revealed that the craniofacial Class II, div. 1, div.2 pattern was associated with increased frequency of arches and ulnar loops and decreased frequency of whorls, whereas in Class III, there was an increased frequency of arches and radial loops with decreased frequency of ulnar loops. In predicting Class III malocclusion, based on frequency of arches, the sensitivity values were found to be higher and more reliable than the sensitivity values of Class II, div.1 and div.2 malocclusion.

The purpose of present study was to compare the effect of 15 seconds & 60 seconds of etching of young permanent teeth in vitro with 50% phosphoric acid gel using scanning electron microscope. 25 pairs of enamel surfaces selected for the study were divided into 3 experimental groups. The control group consisted of unetched enamel surfaces. In Group II, the effect of 50% phosphoric acid gel was compared with 37% phosphoric acid solution for 15 seconds whereas in group III, the effect of 15 seconds & 60 seconds of etching with 50% phosphoric acid gel was compared. The degree of etching pattern was evaluated by using scoring pattern from 1-3. Results showed no significant difference between the etching pattern obtained with the use of 37% solution and 50% gel for 15 seconds. But it was observed that etching with 50% for 15 seconds resulted in equal or even an enhanced etching pattern as compared to the pattern obtained in 60 seconds with 50% phosphoric acid gel.

An eight-year-old girl was referred for the management of recurrent bleeding from the lower, left gingival region and a diffused swelling on the left side of her face. Doppler study and carotid angiogram were suggestive of an arteriovenous malformation. Segmental mandibular resection was performed after ligation of the left external carotid artery. Post-operative period was uneventful and there has been no recurrence of the lesion till date.

A three-year-old boy reported to the Dept. of Pedodontics with the complaint of swelling in the lower left side of the mouth. The radiographic and histologic study revealed the case to be a complex odontome which is rare in deciduous dentition.

Fusion of teeth results from abnormal events in the embryologic development of teeth. In most cases the clinical and radiological findings allow only a presumptive diagnosis to be established since the specific terminology described refers to the etiology of the process, which often cannot be established. An unusual case of bilateral fusion in primary mandibular incisor region in a four-year-old boy is reported.

The present study was carried out on 40 municipal school children in the age group of 12-14 years to evaluate the effectiveness of daily supervised rinsing with specially formulated alum containing mouthrinse on plaque and gingivitis inhibition. The results of this 2 week study demonstrate that a mouthrinse containing 0.02 M Aluminium has significant effect on plaque inhibition. There was a reduction in gingivitis but it was not significant statistically.
