Objective: The establishment and maintenance of normal occlusion constitutes one of the important objectives of pediatric dentistry. There are very few studies assessing the occlusal characteristics of primary dentition in the preschool children. The objective of this study was to assess the occlusal characteristics of primary dentition and difference in various parameters, in children between 3 and 5 years of age.Materials and methods: Eight hundred and eight healthy children, of age group between 3 and 5 years, and having full set of deciduous dentition, were selected by random sampling. Examination and recording of occlusal characteristics were done by single examiner.Results: Flush terminal molar relationship was seen in 67.9% of children. Statistically significant (χ2 = 47.835, p = 0.001) increase in mesial step molar relationship was seen with age. The class I canine relationship was the most prevalent canine relation, however the agewise changes of canine relation were not statistically significant. Anterior open bite was observed in 0.2% of children, which was less than the prevalence reported earlier in literature. 91.2% of children had overjet of 1 to 2 mm. The incidence of anterior and posterior crossbite was 0.4%. No cases of infraocclusion and scissors bite were observed.Conclusion: There is change in deciduous molar relationship as age increases. There is a significant increase in mesial step molar relation in 5 years age group compared to 3 years. The low prevalence of posterior crossbite and anterior open bite is suggestive of lower prevalence of sucking habits in children. Larger sample size may be required to assess the prevalence of infraocclusion and scissors bite.How to cite this article: Bhat SS, Rao HTA, Hegde KS, Kumar BSK.

The aim of the study was to evaluate the extent of surface zone remineralization and the effect of fluoride at the inter-proximal adjacent tooth surface, using restorative materials FusionAlloy, Ketac-Fil and Heliomolar. Ninety extracted molar teeth were used of which 45 were placed in artificial caries for 10 weeks. The remaining 45 teeth were filled with the respective restorative materials, mounted with the artificial carious teeth in proximal contact with plaster and placed in artificial saliva for a period of 28 days. Finally, sectioning of artificially carious teeth was done mesio-distally and observed under the optical microscope and scanning electron microscope. Comparison among the groups was done by one-way analysis of variance [ANOVA] and Fischer's F test. Intercomparison between the groups was done by using Dunnett's t-test. Results obtained from transmitted electron microscopic and scanning electron microscopic observations were almost similar with the Ketac-Fil and Heliomolar showing better results in surface zone remineralization compared to FusionAlloy. Also, Ketac-Fil is a good material in releasing fluoride to remineralize enamel when compared to Heliomolar and FusionAlloy. Thus, it can be used mainly in class II cavity restorations of primary and permanent dentitions due to the potential ability of fluoride containing glass ionomer cements and composite resins to remineralize incipient carious lesions on adjacent teeth.

Objective: To compare the safety and efficacy of two orally administered conscious sedation agents, Triclofos 70mg/kg and Midazolam 0.5mg/kg in pediatric dental patients. Study Design: In this cross over study twenty four sedation sessions were carried out with twelve children between the age group of 3 to 9 years. Children exhibiting negative behavior according to Frankl behavior rating scale (Rating No.2) were selected. Patients were randomly assigned to receive oral midazolam 0.5mg/kg or triclofos 70mg/kg. The alternate drug was administered at the next appointment. Patients' behavioral responses were recorded using a scoring system established by Houpt et al and modified by Badalaty et al considering the degree of sleep, body movement, crying and overall behavior. Scoring was done for both midazolam and triclofos session as well as for the session which was tried without medication. Ratings were made during all the procedures like injection of LA, extraction, cavity preparation, restoration and pulp therapy. Statistical analysis was done using Friedman test and Wilcoxon sign rank test. Results: Both the drugs showed significantly higher scores when compared to the session which was tried without medication although the scores for midazolam were significantly higher than triclofos. Conclusion: Oral midazolam in a dose of 0.5mg/kg is more effective in regulating patient behavior when compared to triclofos.

AimThe aim of this study is to evaluate the remineralization potential of Clinpro XT varnish containing tricalcium phosphate (TCP) and MI varnish containing casein phosphopeptide (casein phosphopeptide–amorphous calcium phosphate, CPP–ACP).Materials and methodsThirty premolar teeth were taken and divided into three groups. Samples were sliced mesiodistally into buccal and lingual halves using a diamond disk bur. The buccal halves of the teeth were used for the study. Artificial caries like lesions were produced and evaluated with Diagnodent. The samples in each group were treated with the respective remineralizing agent (except for the control group) at every 24 hours for 7 days and the surfaces were assessed using Diagnodent to record the values after the remineralization procedure. The Diagnodent values obtained were tabulated and statistically analyzed using one-way ANOVA and Tukey's multiple comparison tests.ResultsThere was a significant difference between the values calculated before and after remineralization in all the three groups.ConclusionThe study findings showed that MI varnish containing CPP–ACP had the highest release of fluoride as compared to the Clinpro fluoride releasing varnish.Clinical significanceMI varnish is a 5% NaF varnish containing CPP–ACP to give an exceptional fluoride varnish that releases more bioavailable fluoride, calcium, and phosphate, hence, can be used successfully in remineralization of early carious lesions. CPP–ACP can be used in the clinical practice for reversing or arresting the early carious lesions.How to cite this articleVarma V, Hegde KS, et al.
