Xylitol-containing Chewing Gum for Caries Prevention in Students with Disabilities: A Randomised Trial.

Purpose: This cluster randomised controlled trial evaluated the effectiveness of a school-based xylitol chewing-gum programme on caries prevention among students with visual or hearing impairment.

Materials And Methods: The study compared xylitol gum plus oral health education (intervention group, n = 93) with oral health education alone (control group, n = 81) among students aged 7-18 years in special needs schools in Khon Kaen, Thailand. The primary outcome was caries onset rate measured as the change in caries onset on tooth surfaces.

Breastfeeding Duration and Childhood Caries: A Cohort Study.

This cohort study was conducted in Khon Kaen, Thailand, to test the hypothesis that a longer breastfeeding duration increases the risk for dental caries in primary teeth. We collected information on infant feeding practices and potential confounders using a structured questionnaire to interview mothers or caregivers during the second trimester of pregnancy and after birth at 21 days and at 3, 12, 18, 24, and 36 months. Regardless of other liquids and foods, full breastfeeding was defined as feeding breast milk but not formula, while any breastfeeding was feeding breast milk with or without formula.

Adverse birth outcomes and childhood caries: a cohort study.

Objectives: To examine the association between adverse birth outcomes and dental caries in primary teeth.

Methods: This study included children in Khon Kaen, Thailand, who participated in the Prospective Cohort Study of Thai Children. Preterm was defined as a birth at <37 weeks gestation, low birthweight (LBW) as birthweight <2500 g, and small-for-gestational age (SGA) as birthweight <10th percentile of expected weight for gestational age.

Molar incisor hypomineralization and dental caries in six- to seven-year-old Thai children.

Purpose: This study aimed to determine the prevalence of molar incisor hypomineralization (MIH) in Thai children and evaluate the association between MIH and dental caries in the permanent dentition.

Methods: A cross-sectional study was conducted among six- to seven-year-old participants of a birth cohort study in Khon Kaen, Thailand. MIH was examined by one calibrated dentist using European Academy of Pediatric Dentistry criteria.

Factors associated with molar incisor hypomineralization in Thai children.

Molar incisor hypomineralization (MIH) is a qualitative developmental enamel defect that affects one to four permanent first molars, with or without involvement of permanent incisors. Its etiology is of systemic origin, but is not well understood. Therefore, we conducted this cross-sectional study to examine pre-, peri-, and postnatal risk factors for MIH among children, 7-8 yr of age, in urban areas of Khon Kaen, Thailand.
