Impact of Detecting Initial and Active Caries Lesions in Primary Teeth
Dental CariesThe present study aims to evaluate the impact of detecting active initial caries lesions in primary teeth regarding effectiveness, cost-effectiveness, applicability (acceptability and satisfaction) and quality of life. For this, 248 children 3-6 years with complete primary dentition will be examined and treated in a mobile dental unit, which will temporarily be parked in public schools of Sao Paulo. The caries detection will be conducted using the International Caries Detection and Assessment System (ICDAS) and, depending on allocation, an adjunct criterion for caries activity assessment. Children will be randomized in two groups according to the caries threshold to be detected: Group A (only advanced lesions will be detected and treated, independently of their activity status) and Group B (all caries lesions, including initial ones, will be detected and all active lesions will be treated). After this, the treatment plan for each child will be made according to strategies mentioned above. Data concerning the cost-effectiveness of the procedures, acceptability / satisfaction of children and quality of life will be collected after diagnosis, after the end of treatment and 12 and 24 months from the initial examination. For comparison between groups, multilevel regression analyses will be performed. The primary outcome will be sites which need of operative treatment during the follow-up periods and the secondary outcomes will be the cost-effectiveness of each strategy, the acceptability / satisfaction of the child and the impact on quality of life.

Probiotics in Prevention of Allergies, Obesity and Caries
EczemaAllergy3 moreDuring the period of 2000-2003, 179 healthy, term infants with no previous signs of allergic disease were recruited and randomized to daily intake of cereals with or without the addition of Lactobacillus paracasei subspecies paracasei strain F19 (LF19) from 4-13 months of age. The effects of LF19 on gut microbial composition, infections, allergies, immunological development, growth and blood lipids were monitored. Of 179 included infants, 171 completed the study. The study product was well tolerated with no observed side effects. Compliance was excellent. In a follow-up study, the aim is to investigate the long-term effects of feeding LF19 during weaning on allergies, immune programming, overweight, gut microbial composition and oral health in 8-year old children. The investigators' primary outcome will be to determine whether daily intake of LF19 during weaning results in less eczema at 8 years of age, and if the preventive effect encompasses also respiratory allergies and immunoglobulin E (IgE) - sensitization. The long term effects on gut microbial composition, overweight and metabolic markers will be investigated. Furthermore, the possible preventive effects of LF19 on caries will be assessed.
Effectiveness of Pit and Fissure Sealants in the Prevention of Dental Caries
CariesDentalThis randomized clinical trial is aimed at testing the efficacy of pit and fissure sealants, in a current environmental context different from that of the seventies and eighties. It has a split mouth design. 4OO subjects are included and the duration of follow up is 2 years.
Dental Caries Prevention by a Natural Product
Dental CariesThe objective is to conduct an RCT to evaluate the effectiveness of Licorice in comparison to standard caries preventive measures for the prevention of new carious lesions in high caries risk patients.
Delivery of Polyphenols in Gum as an Anti-Caries Agent
Dental CariesThe short-term effects of chewing gum containing xylitol and/or blackberry extract on oral microbiota was studied. Fifty healthy adults participated in a randomized, placebo-controlled, cross-over design study.
Long-term Effects of a Lay Health Advisor Intervention on Immigrant Children's Caries
Caries,DentalThe aim of this study was to evaluate the long-term effectiveness of a lay health advisor (LHA) intervention on immigrant children's caries and preventive behaviors.This randomized controlled trial included mother-child pairs in the intervention group (IG) and a brochure-only control group (CG), respectively. The IG received a four-week one-on-one session by an LHA on caries-related knowledge and brushing techniques. Baseline and follow-up surveys were used to collect the data in caries experience and maternal caries preventive behavior.
Effect of Chewing a Calcium Supplement Before Fluoride Rinse on Salivary Fluoride
Dental CariesThe anticaries effect of fluoride is through the increase in fluoride presence and retention in the oral fluids, reducing dental demineralization and enhancing remineralization. Previous studies showed that a preapplication of calcium (in a rinse) prior to administration of fluoride greatly enhances fluoride concentration in the mouth and the anticaries effect of fluoride. The hypothesis of this study is that the same can be achieved by chewing a calcium supplement prior to a fluoride rinse. The first goal is to determine if chewing these calcium supplements will increase calcium concentration in the oral fluids above baseline levels. Secondly, the calcium supplement with the highest calcium release will be tested before a fluoride rinse to assess the increased retention of fluoride in the oral fluids when compared with the fluoride rinse alone. In both parts, healthy volunteers will participate and saliva will be collected to assess calcium and fluoride concentration.
Bedtime Routines and Children's Health
MyopiaDental Caries2 moreIn Taiwan, the prevalence of sleep problems, myopia, and dental caries in school-age children is high. Little is known regarding the implementation of oral and vision health outcomes around bedtime. A bedtime routine intervention was conducted to improve children's oral, vision and sleep health.
