ABSTRACT

Fluorides and chlorhexidine are technologies that are 65 and 40 years old, respectively. This overview argues that current methods of caries prevention are not effective for the high caries risk patient. In this review examples, arguments and recommendations are provided to address the high caries risk patient that include: failure of comprehensive chemical modalities treatments to address the high caries risk patient; ecological alteration - would this be an effective approach?; and biomaterials and oral microbiome research to address the high caries risk patient.

ABSTRACT

The aims of this study are (1) to describe issues related to recruitment of mothers participating in a clinical trial of transmission of mutans streptococci (MS) from mother to child in Bauru, Brazil and (2) to perform cross-cultural and temporal comparisons of levels of infection of the MS in mothers of Bauru. A total of 1422 mothers were visited at their domiciles. Cutoff levels for the MS were established at ≥10(5) CFU/mL saliva. The main reason for a mother not enrolling was not being highly infected by the MS, yet 76% of mothers presented with levels ≥10(5) CFU/mL saliva. Recent studies in industrialized countries showed a negative coefficient for linear tests indicating significant decline overtime in the levels of MS in mothers. Intercountry comparisons for mothers' salivary levels of the MS with the Bauru study as the reference revealed significant differences with studies conducted in the last two decades.

ABSTRACT

OBJECTIVE: The purpose of this study was to investigate compliance of long-term xylitol and sorbitol chewing gum regimens in adult women participating in a double-blind randomized controlled clinical trial. DESIGN: The participants included 122 mothers (age range: 16-35 years) residing in the city of Bauru, São Paulo, Brazil. Compliance with the xylitol and sorbitol chewing gum regimens was assessed by weighing, with a precision balance, all used gums returned in zip-lock bags during the study period of 33 months. The total number of returned bags in both chewing gum groups was computed and the differences between groups were determined by one-way ANOVA. Compliance was further categorized into excellent, good, fair or poor based on the distribution of the combined data for both groups by quartiles. These distributions for the xylitol and sorbitol groups were subjected to chi-square analysis. RESULTS: Compliance was always superior for the xylitol group in all categories. These distributions were, however, not significantly different in statistical terms. Average compliance in the xylitol chewing gum group was significantly higher when compared to the sorbitol chewing gum group (p=0.0481). CONCLUSIONS: The results suggest that compliance, and possibly acceptance in this population, was superior for xylitol chewing gum than for sorbitol chewing gum.

ABSTRACT

OBJECTIVE: The purpose of this study was two-fold: 1) to determine the effects of mechanical and chemical modalities treatments on periodontal clinical and microbiological parameters of mothers; and 2) to determine the subsequent colonization of periodontal pathogens in tongue samples from their infants. DESIGN: A total of 168 mothers met inclusion criteria to participate in a randomized double-masked placebo-controlled clinical trial. Of those, 121 mothers (and their infants) of 158 seen at baseline provided complete data during study protocols from when their infants were 3 months old until the infants were about 2 years old. Treatments consisted of a combination of xylitol chewing gum, fluoride and chlorhexidine varnishes. The control/placebo group received sorbitol chewing gum and placebo varnishes. The effect of these treatments on periodontal clinical and microbiological parameters of mothers and on microbiological parameters of their infants was assessed by generalized estimating equation models. RESULTS: Microbiological outcomes using the BANA Test were lower for the majority of the visits in the test group when compared to the control/placebo group. These differences, however, were not statistically significant. Similarly, mean PBS results were lower for all follow-up visits for test-group mothers when compared to the control/placebo group's mothers, but of no statistical significance. Colonization of the tongue in infants by periodontal pathogens as measured by the BANA Test showed no distinct patterns concerning the stability of colonization of periodontal pathogens throughout the study period, albeit slightly superior for the test group. CONCLUSIONS: We have demonstrated that a combined chemical modalities treatment consisting of xylitol chewing gum, fluoride varnish and chlorhexidine varnish was moderately superior to control/placebo treatments on periodontal clinical and microbiological parameters of mothers throughout the study period, but of no statistical significance. Similar results were found for the infants in the test group when compared to infants of the control/placebo groups.
