Cluster sampling technique was used in the selection of children for this study.

Male constituted 65.9% while female was 34.1%. Thirty five (25.4%) are from the juvenile correctional home (institutionalized street children) while 103 (74.6%) are from the streets. The prevalence of dental caries among the children generally was 29.0%, while that of dental trauma was 18.8%.Conclusion: The significant predictors of dental caries were gender, tooth hypoplasia and the presence of visible plaque on the anterior teeth while those of dental trauma were lip competence, substance use, age and gender.Keywords: Street children, Juvenile home, Caries, Traum
