The aim of this study was to determine the difference in shear bond strength between Composite, Compomer and Resin modified glass ionomer cement in primary and permanent teeth. Thirty extracted primary molars and thirty premolars were selected and buccal surfaces of all the teeth were made smooth with the help of 300 grit silicon carbide paper. These specimens were then divided into 6 groups. Restorative materials were placed on the buccal surfaces of respective specimens with the help of acrylic template. All the specimens were subjected to thermocycling and shear bond strength was tested under the Honsfield testing machine and results were recorded in megapascals (MPa). The resultant scores were tabulated and statistically analysed. It was observed that in case of primary teeth resin modified glass ionomer exhibited significantly higher shear bond strength as compared to composite and compomer, where as on permanent teeth composite demonstrated a significantly higher shear bond strength than that of the resin modified glass ionomer and compomer, where as compomer gave poor shear bond strength in both primary and permanent teeth.

Restoration of primary maxillary incisors, severely destroyed by trauma or caries is a commonly faced problem in a Pediatric dental clinic. Most cases are observed in children with early childhood caries. In the past, the only option would have been to extract the affected teeth and replace them with prosthetic substitutes. However, the availability of natural crowns and roots would allow the use of biologic restorations to preserve the integrity of patient's natural dentition as presented in this case report.

The primary objective of this study was to compare the efficacy of sodium fluoride (0.05%), chlorhexidine (0.12%) and triclosan (0.3%) mouth rinses in reducing the mutans streptococci count in saliva. 60 subjects in the age group of 12 to 14 years were selected from the schools of Mumbai and were equally divided into 4 groups. First 3 groups were test groups and the 4th group was control group. The subjects were instructed to rinse one full marked measure of mouth rinse for 1 minute, twice daily. Salivary samples were collected at baseline and after 2 weeks and cultured on M.S.B.agar. The number of mutans streptococci colonies were counted on agar medium. The results of the study confirmed that chlorhexidine mouth rinses are more efficient in reducing mutans streptococci count in saliva as compared to other mouth rinses.

Eosinophilic granuloma is the most benign disorder of the triad commonly known as histocytosis X. In this article a case of a 6 year old female child with multiple eosinophilic granuloma with additional liver dysfunction and its oral manifestation is presented. This case demonstrated that oral findings, may be an early manifestation of the disease, definitive diagnosis needs to be determined by correlation of the clinical findings with histologic features. For the duration of 8 years the case has been followed up, there has been a progressive healing of the lesion, the clinical manifestations of the disease resolved with only chemotherapy and provided a very good prognosis.

With the dawn of the new century, dentistry has seen a new face in the fields of diagnosis, treatment and prevention. Twenty one children were asked to brush their teeth for five days. The brushes were put in Robertson's Cooked Meat broth and cultured. Growth of Streptococcus Mutans were seen. These brushes were then placed in disinfectants such as 0.2% chlorhexidine gluconate (Gp I), 1% sodium hypochlorite(Gp II) and water (Gp III) for 24 hrs and then cultured. Disappearance of growth of microorganisms was seen in Gp I and Gp II and remnants of growth seen in Gp III. It can be concluded that the use of disinfectant is a must for every individual at regular intervals.

Transmigration of mandibular canine is a rare elusive phenomenon described in dental literature. The eruption of such transmigrated canines is even rarer. Two rare cases one of midline mandibular canine and the other of transmigrated mandibular canine across the midline and erupted distal to the opposite lateral incisor are presented. The transmigrated canine maintained its nerve supply from the original site. It is suggested that on routine evaluation of orthopantomograms when the dentist finds an excessive mesial inclination of the unerupted mandibular canine at 8-9 years associated with proclination of lower anteriors. increased axial inclination of the unerupted canine and an enlarged symphyseal cross section area of the chin, it is best to keep such a patient under routine evaluation.

Trauma to the anterior teeth is relatively common among children and teenagers. Reattachment of a fractured fragment to the remaining tooth can provide better and long lasting esthetics, improved function, a positive psychological response and is a faster and less complicated procedure. This article discusses fragment reattachment technique and presents clinical case of coronal fracture involving enamel and dentin.

This study was conducted on 5554 children aged 5-13 years old with the objectives of recording the prevalence of oral habits among North Indian children according to sex. These children were selected from the schools of Delhi. The sample represented the entire school-going population of Delhi in the age group of 5-13 years. Statistical analysis was carried out using BMDP software and sex differences were calculated by using Fisher's exact test. The results showed that the prevalence of oral habits in Delhi school going children was 25.5%. Tongue thrust was the commonest habit (18.1%) followed by mouth breathing (6.6%). Thumb sucking was relatively less common habit and seen in only 0.7% of children. There were no significant differences between boys and girls for the prevalence of oral habits. However, for the specific habit types there was a sex difference. Thumb sucking was more common in girls (1.0%) when compared with boys (0.4%) and this difference was statistically significant (P < 0.001). There was a reverse trend for the mouth breathing, which was more common (P < 0.001) in boys (7.8%) than girls (5.3%). There were no differences for tongue thrust habit between boys (17.5%) and girls (18.6%).
