Assessment of caries on the first permanent molars in a group of seven- to thirteen-year-old schoolchildren: Comparison of DMF and ICDAS systems.

OBJECTIVES: The objective of this study was to compare ICDAS and DMFT/S in the evaluation of caries status of the first permanent molar in 200 children aged 7 to 13 years. METHODS: This was a cross-sectional design study. Participants were selected from two private schools in Lebanon. The examinations were performed by two trained and calibrated examiners using a dental mirror and a WHO probe. The number of decayed (D), missing (M) and filled (F) teeth was recorded in DMFT/S form, and the numbers related to D, M and F were then added to record the DMFT/S value (D1MFT/S, D2MFT/S and D3MFT/S). In the ICDAS, the assessment of caries associated with restorations and sealant was recorded. Student t tests/and Mann-Whitney tests were used to compare the continuous variables. Chi-square tests and Fisher exact tests were used to compare the categorical variables. RESULTS: The average age of the participants was 9.21 ± 1.927 (7-13 years old). No significant difference was found between the mean time to score DMFT, DMFS and ICDAS indices (-p-value > 0.05). The prevalence of caries with D1MFS, D2MFS and D3MFS was 80.5%, 54% and 30.5%, respectively. However, the prevalence of caries with ICDAS II was 77.5%. CONCLUSION: The DMF index is an international user-friendly system that shows the carious history of teeth. However, the ICDAS assesses the different stages of caries and describes the restorative status of the tooth, promoting new preventive approaches and curative needs. More studies should be done to confirm these findings.

Papillon-Lefèvre Syndrome: Diagnosis, Dental Management, and a Case Report.

AIM: This paper revisits Papillon-Lefèvre syndrome (PLS), addresses its diagnostic update and dental management, and reports a case of a 5-year-old Lebanese patient with consanguineously married parents. BACKGROUND: PLS, also known as "keratoris palmoplantaris with periodontopathia" and "hyperkeratosis palmoplantaris with periodontosis," is an extremely rare autosomal-recessive trait that combines a diffuse palmoplantar hyperkeratosis and a severe generalized, progressive prepubertal form of a precocious form of juvenile, aggressive periodontitis. CASE DESCRIPTION: We are reporting a 5-year-old boy that sustained a spontaneous loss of all his primary teeth. At consultation, he was under treatment for hyperkeratosis of his palms and soles. Detailed family history of the child revealed that the patient's parents, grandparents, and relatives were consanguineously married and two of his cousins displayed similar clinical signs (palmoplantar hyperkeratosis and premature loss of deciduous and most of the permanent teeth). CONCLUSION: PLS is an extremely rare disorder that usually becomes apparent from approximately 1-5 years of age. Genetic counseling should always be suggested to parents of affected children, informing them of chances of their offspring having the inherited disease.
