Abstract

Early childhood caries is now affecting the children in dangerous proportions. There is a widespread loss of the tooth material irrespective of the type of the carious lesion. Restoration of such lesions with a strong permanent bond between the dental tissues and the restorative dental materials would be a highly desirable requisite of any restorative material. Ultramorphological characterizations show that the interfa-cial morphology and the chemical characterization of the bonding systems appear to be strongly associated with each other and, therefore, 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.

Highlights

Childhood is marked by tremendous growth and development of the face and the dentition, both of which require regular monitoring and supervision of a dental professional
From the statistical analysis of the microleakage study, there was no statistically significant difference between the two groups with p-value of 0.206 (p > 0.05), but from the mean value of both the groups, it may be concluded that the marginal leakage may be more in group C2 (Xeno III) when compared with group C1 (Prime and Bond NT)
The results of the present study are complementary to the results reported by Stalin A, Varma BR et al[24] (2005) who evaluated the tensile bond strength, fracture mode and microleakage of fifth generation and sixth generation bonding system and found no statistically significant difference between two groups concluding that, the self-etching adhesive is better for bonding in primary dentition

Summary

Introduction

Childhood is marked by tremendous growth and development of the face and the dentition, both of which require regular monitoring and supervision of a dental professional. Among the more common oral conditions, early childhood, dental caries is the preeminent concern because of its tremendous prevalence and consequences. Nearly one in five (18.7 %) US children between the ages 2 to 4 have experienced visually evident tooth decay.[1]. National surveys conducted during the past three decades have demonstrated a decline in the overall mean levels of clinically detectable dental caries in the US children and adolescents.[2] dental caries remain the single most common disease of childhood that is neither self-limiting nor amenable to short-term pharmacological management. More than 80% of the pediatric population is affected by dental caries by age 17. In a study conducted by Balwant Rai et al (2007) the mean DMFT was found to be 2.82, 2.87, 3.40 and 3.15 in 9, 10, 11 and 12-year-old children, while the mean DMFS was found to be 3.82, 3.87, 3.76 and 4.26 respectively.[3]
