Impact of Intelligence Quotient (IQ) on Dental Caries amongst Socially Handicapped Orphan Children and Children Living with Their Parents.

Objective: To evaluate the IQ and dental caries status of socially deprived orphan children and compare with children living with their parents. Study design: For comparison, 100 children in age-group 7-11 years, were divided in two groups: 50 orphanage children (orphanage-group) and 50 school-going children living with their families were included (home group). Raven's colored progressive matrices test was used to record the intelligence quotient (IQ) and dental caries status of children was recorded using dmft Index. Results: There was statistically significant difference between children with different levels of IQ for both the groups. However, the majority of children who belong to below average IQ score had higher dental caries. Conclusion: Children with better IQ had less dental caries. There was no difference in IQ and DMFT/dmft score between both the genders. The overall DMFT/dmft was high in children living with their parents when compared to orphanage children.

Accessory Central Cusp in the Maxillary Second Primary Molars: A Rare Entity among the Rare.

Central accessory cusp in primary molars is an extremely rare condition which is due to abnormal proliferation and folding of inner enamel epithelium during morphodifferentiation stage of tooth development. The extension of the pulp in the cuspal area is often the reason for early involvement of pulp by the caries process. Therefore, early diagnosis and treatment planning is necessary to maintain the integrity of primary dental arch. This article reports such a case of central accessory cusps involving maxillary second primary molars. How to cite this article: Chandra B, Das M.

Enamel thickness in primary teeth.

OBJECTIVE: The aim of this study was to determine the enamel thickness of all primary teeth in both maxilla and mandible. STUDY DESIGN: An in vitro study was performed with fifty primary teeth including five each of central and lateral incisor, canine, first and second primary molars in both maxillary and mandibular region. Samples were mounted on wax sheets and scanned using a 64-slice CT scanner which were then 3D reconstructed. Three serial slices were obtained from the middle of the coronal portion of each tooth. Volume rendering was done to differentiate three distinct zones of enamel, dentin and the pulp from each slice. A box was constructed touching the borders of the image on all the surfaces and the mid-point of each side was taken to measure the enamel thickness. RESULTS: Tests used were ANOVA, Post-hoc Tukey's test and student's paired t-test. Enamel thickness was not the same on all the sides. Intergroup comparisons between maxillary anterior and posterior teeth showed difference in enamel thickness. On comparing the mandibular anterior and posterior teeth, the posteriors showed a greater value of enamel thickness on all the sides (p < 0.05). CONCLUSION: Primary enamel does not follow the same thickness patterns on all sides. It is also different in each primary tooth. There was an increase in enamel thickness in posterior teeth on comparison to their anterior counterparts in both maxilla and mandible. Enamel thickness was more on the distal aspect compared to mesial in all samples.
