PURPOSE The purpose of this study was to assess the susceptibility of children to the future development of caries following comprehensive treatment for early childhood caries (ECC) under general anesthesia. METHODS The patients selected for this retrospective study were identified by analyzing dental records of children receiving treatment at the(More)
BACKGROUND Autism spectrum disorder (ASD) is a lifelong neurodevelopmental disorder. The authors conducted a study to evaluate the demographics, caries experience and behavior of patients with ASD and compare these characteristics with those of patients without ASD (unaffected patients). METHODS The authors reviewed patients' charts and identified a group(More)
BACKGROUND Autism spectrum disorder (ASD) is a neurodevelopmental disorder categorized into autism, pervasive developmental disorder - not otherwise specified (PDD-NOS) and Asperger syndrome. AIMS To identify factors associated with the behaviour of patients with ASD in a dental setting, use of general anaesthesia (GA), and protective stabilization. (More)
The placement of orthodontic appliances creates a favorable environment for the accumulation of a microbiota and food residues, which, in time, may cause caries or exacerbate any pre-existing periodontal disease. The purpose of the present study was to compare the total bacterial counts present on metallic and ceramic orthodontic brackets in order to(More)
OBJECTIVE The purpose of this study was to determine the effectiveness of laser-activated irrigation by photon-induced photoacoustic streaming (PIPS) using Er:YAG laser energy in decontaminating heavily colonized root canal systems in vitro. MATERIALS AND METHODS Extracted single-rooted human teeth (n=60) were mechanically and chemically prepared,(More)
PURPOSE Severe early childhood caries (ECC) results from bacterial acid production in an acidic environment. The purpose of this study was to determine Streptococcus mutans, Streptococcus sobrinus, and acid-tolerant counts in severe early childhood caries. METHODS Two- to 6-year-olds with severe-ECC (N=77) or who were caries-free (N=40) were examined.(More)
Previous studies have shown a positive correlation between salivary IgA antibody levels to Streptococcus mutans and caries resistance in adults. In this study, enzyme-linked immunosorbent assay (ELISA) was used to compare IgA antibody levels with S. mutans in whole and parotid saliva from 20 caries-susceptible (CS; DMFS > 5) and 20 caries-resistant (CR;(More)
The objective of this study was to evaluate reported bruxism among children affected by attention deficit hyperactivity disorder (ADHD). Thirty children diagnosed with ADHD and 30 healthy age and gender matched controls participated in the study. All subjects were examined for dental attrition, and the parents were asked for signs and symptoms of bruxism in(More)
PURPOSE The purpose of this study was to examine factors associated with early childhood caries (ECC) and to develop a profile of risk factors for Hispanic families affected by this condition. METHODS Sixty Hispanic families with at least 1 child affected by ECC and 60 Hispanic families without any affected children were included in the study. Data was(More)
