These sweeteners along with their low endogenic pH form a high cariogenic formulation. Thus, nonsucrose (noncariogenic) or sugar-free medications are needed to be prescribed along with proper oral hygiene care to the children under medication.

Introduction:Dental caries remains the most important dental health problem in developing countries. Application of varnish on tooth surfaces is shown to promote the uptake of firmly bound fluoride by enamel, which is considered important. Along with the incorporation of fluoride into the crystalline lattice, there is formation of calcium fluoride compounds on enamel.Methodology:Seventy deciduous canines were covered with nail polish. A window measuring 4 mm × 4 mm was left on their buccal surface, These were randomly assigned to seven groups (n = 6): S: sound enamel not subjected to any regimen or treatment; N: negative control, subjected to the pH-cycling regimen without any treatment; D1 and D2: subjected to the pH-cycling regimen and treated two times daily with 1100 and 500 ppm F dentifrice, respectively; VF: fluoride varnish (subjected to F-varnish before and in the middle of the pH-cycling regimen); and VF + D1 and VF + D2. After a period of 10 days, sectioning of teeth was done, and enamel demineralization was measured.Results:The combination of dentifrice and varnish (groups VF + D1 and VF + D2) significantly reduced demineralization compared with the N group at all distances evaluated (P < 0.05), but the combination did not differ from the dentifrice groups at most distances from the surface (P > 0.05).Conclusion:The results of this study suggest that the combination of F-varnish with dentifrices containing 500 or 1100 ppm F is not more effective in reducing demineralization in primary teeth than the isolated effect of dentifrice containing 1100 ppm.

Background Over the years, coronally advanced flap and the use of guided tissue regeneration have been among the more successful techniques in treating gingival recession. The present study compared the relative efficacies of these two techniques in treating gingival recession. Methods Twelve patients presenting with localized identical anterior recessions were taken up in a split mouth design for the study. One site was randomly assigned to be treated with coronally advanced flap supported by membrane while the other was treated with coronally advanced flap alone. Changes in clinical parameters, such as recession width, recession depth, surface area of the recession defect, width of keratinized tissue, gingival status, probing pocket depth and clinical attachment level were measured at baseline and at 3 and 6 months postoperatively. Results In the 10 patients that were followed up, both treatments resulted in a significant gain in root coverage amounting to a mean gain of 66.49% in the membrane group and 65.56% in the CAF group. The differences in root coverage and the clinical attachment level gains between the groups were not significant. However, significant gain in the width of keratinized tissue was seen in the membrane group after treatment. Conclusion This study suggests that coronally advanced flap procedure provides a predictable, simple and convenient technique in the treatment of localized class I gingival recession. Combining this technique with the placement of a bioabsorbable membrane does not seem to improve the results. The addition of a membrane, however, increases the width of keratinized tissue.
