Aim: To evaluate microleakage of Nanoionomer (3M ESPE Ketac(™) N100 Light cured Nanoionomer Restorative) and Nanocomposite (3M ESPE Filtek(™) Z350 XT Universal Restorative) restorations, immersed in fruit drink, fresh fruit juice and soft drink., Study Design: Eighty caries free maxillary premolars extracted for orthodontic purpose were used for the study. Class V cavities were prepared and restored with Nanocomposite on buccal surface and Nanoionomer on the palatal surface. The teeth were thermocycled following the restoration. The experimental groups comprised of 72 teeth (3 groups comprising 24 teeth each for fruit drink, fresh fruit juice and soft drink), while remaining 8 formed the control group. Each of experimental group was further divided into three subgroups (low, medium and high immersion). The teeth were finally immersed in Rhodamine B dye, sectioned and evaluated under stereomicroscope. Statistical analyses used were Mann-Whitney test and ANOVA test., Results: The teeth showed statistically significant microleakage as the immersion regime increased. Soft drink group showed highest microleakage followed by fresh fruit juice and fruit drink. Nanocomposite exhibited more microleakage but the comparison was not statistically significant., Conclusion: The three beverages used in the study affected the microleakage of both restorative materials significantly. The microleakage scores increased as the frequency of the immersions increased. Soft drink caused highest microleakage followed by fresh fruit juice and fruit drink.

Dentists often find foreign bodies in the primary dentition of children who habitually place objects in their mouths. The objects are frequently embedded in exposures that result from carious or traumatic lesions or from endodontic procedures that have been left open for drainage. Such bodies are often detected on routine radiographs and, less frequently, during clinical examination. We report a case of a 6-year-old boy who had inadvertently embedded a screw in his mandibular right first primary molar and had forgotten about it until it became symptomatic. The screw was impacted in the exposed pulp chamber due to a large carious lesion in the affected molar. This case report considers the possible medical and dental consequences of placing foreign bodies in the mouth.

Background and Objective: Restoration of carious lesions with a strong permanent bond would be a highly desirable requisite. Ultra morphological characterization shows that observing and understanding the interfacial phenomenon and its quality would be of great importance in the selection of a dental adhesive for its use in pediatric restorative dentistry., Study Design: Human primary molars, indicated for extraction, for reasons like caries, normal exfoliation, pathological root resorption, over-retained and serial extraction, were collected. Teeth were then equally distributed into 2 subgroups each namely B1 - Prime and Bond NT & B2 - Xeno III., Results: The resin tags seen in the samples of group B2 were both qualitatively and quantitatively advanced as compared to group B1. This reveals that the quality of the penetration of the resin was better in group B2., Conclusion: Reduction in the technique sensitivity of any bonding system would always be a preferred factor in pediatric restorative dentistry. Thus the inclination towards the selection of adhesive system may lean towards the self-etching bonding system at this juncture.
