Early Childhood Caries (ECC) are one of the major oral diseases affecting children. ECC adversely affects the children’s as well as their parent/caregivers quality of life. The present study aims to assess the quality of life in children with Early Childhood Caries aged 6–72 months using the Early Childhood Oral Health Impact Scale. It also aims to compare the quality of life between children with pufa scores of > 0 and a pufa score = 0. A total of 238 children aged 6 months to 72 months with ECC and their parent/caregiver were included in the present study. Oral examinations of the children were performed by the principal examiner using the defs and pufa index, which was followed by a personal interview of the 13 items in the Early Childhood Oral Health Impact scale among the 238 parents/caregivers. The results showed that, overall, Early Childhood Caries have a negative impact on children’s quality of life, as assessed by the parent/caregiver. The overall Early Childhood Oral Health Impact scale score ranged from 0–32 (mean ± SD, 14.12 ± 6.72). Children with a pufa score > 0 (mean ± SD, 16.14 ± 6.27, p < 0.001) have significantly lower quality of life than children with pufa score = 0 (mean ± SD, 9.07 ± 4.94, p < 0.001). Early Childhood Caries had a negative impact on the quality of life of children aged 6–72 months. Children with a pufa score of “0” had better oral health-related quality of life than children with a pufa score > 0.
Background:The purpose of this study was to identify the genetic patterns of Streptococcus mutans by DNA finger printing among caries-active, caries-free, and in children with black tooth stains.Materials and Methods:In this in vitro study Ten children with black tooth stains and ten caries-free and caries-active children between 3 and 6 years of age were recruited. Saliva samples were collected using a sterile tube, followed by microbial culture of S. mutans, DNA isolation, and polymerase chain reaction amplification. The molecular weights of each band were converted into binary data, and data were entered into SPSS to generate similarity dendrograms.Results:Dendrogram interpretation of black tooth stain and caries-free samples revealed an identical genetic pattern in 15 samples with high genetic similarity. Dendrogram interpretation of black tooth stain and caries-active samples exhibited a greater genetic diversity.Conclusion:This study concludes that identical genotypes and high genetic similarity among isolates of the caries-free and black tooth stains. Polymorphism and genetic diversity exist between the black tooth stain and caries-active samples.
Introduction: Aesthetic restoration of severely mutilated primary anterior teeth still remains as a special challenge to paediatric dentist. Due to increased parent's concern for aesthetic rehabilitation for their children, paediatric dentist are in a state to improve technique sensitive restorative procedure to improve aesthetic rehabilitation in children.
Aim:The purpose of the study was to evaluate the effect of different root surface treatment on the shear bond strength of glass fibre reinforced post in primary anterior teeth using Universal Testing Machine (UTM).
Materials and Methods:Twenty single rooted primary anterior teeth were selected. Coronal portions of the teeth were sectioned transversally 2 mm above the Cemento-Enamel Junction (CEJ) and specimens were treated endodontically and obturated using metapex. Then the specimens were randomly divided into four groups. Group 1: Control group; Group 2: Chemical surface treatment of the root with 2% chlorhexidine; Group 3: Mechanical surface treatment with mushroom-shaped undercut; Group 4: Combination of mechanical and chemical surface treatments. Samples were tested for shear bond strength. ANOVA and Posthoc Tukey test were used for statistical analysis using SPSS version 20.0.
Results:Combination of mechanical and chemical surface treatments exhibited higher mean shear bond strength (8.41 MPa), followed by mechanical surface treatment (4.68 MPa), chemical surface treatment (3.92 MPa) and control group (2.76 MPa).
Conclusion:Mechanical and chemical surface treatments together led to a improved shear bond strength and increased the retention of the post to the root surface.
Identical genetic distance between child-mother pair showed that, these Streptooccus Mutans were closely related and could have vertically transmitted from their mothers. Different genotypic pattern between caries-free and caries active subjects showed a genetic polymorphism among the Streptococcus Mutans strains.
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
