To Evaluate the Clinical Efficiency of Resin Modified Glass Ionomer Varnish in Preventing Enamel Demineralisation During Orthodontie Treatment

Background and objectives: Fixed orthodontic treatment makes oral Hygiene procedures difficult and may resuit in enamel demineralization. Resin Modified Glass Ionomer Varnish (Clinpro XT Varnish) reduces the incidence of enamel demineralization. The objective of this study has been clinically evaluate the effects of RMGIV (Clinpro XT Varnish) application, incidence and progress of enamel demineralization in patients undergoing orthodontic treatment. 30 subjects seeking orthodontic treatment were selected from patients visiting Department of Orthodontics and Dentofacial Orthopedics A. B. Shetty Memorial Institute of Dental Sciences, Mangalore. The subjects were divided into Test and Control group. The study was divided into two parts: ♦ Visual evaluation – incidence of white spot lesion and their progress for six months. ♦ SEM (Scanning Electron Microscopic) evaluation to compare level of surface roughness on samples of both the groups. No White Spot Lesions was clinically appreciable in either Group A or Group B. Oral Hygiene Index of all patients was scored and compared between Group A and Group B. The scores were statistically evaluated which proved to be statistically significant with ‘p’ value below 0.001 with better oral hygiene in Group A. After extracting the teeth, SEM images of surface of the teeth was graded and statistically evaluated with Pearson's Chi square test.The results were significant with ‘p’ value below 0.001 which indicated increased surface roughness in Group B compared to the Group A patients. Use of Resin Modified Glass Ionomer Varnish (Clinpro XT Varnish) as an adjunctive to thorough oral hygiene measures and has proven to be effective in reducing enamel demineralization significantly although not completely. The oral hygiene also improves but, is it the effect of active ingredient of the varnish is not confirmable under this study design.

A CLINICAL COMPARISON of IN -OFFICE MANAGEMENT OF DENTIN HYPERSENSITIVITY IN A SHORT TERM TREATMENT PERIOD

Objective: To determine the differences in efficiency of four desensitizing agents in relieving dentin hypersensitivity in a time period of 2 weeks. Material and methods: 50 participants who responded positively to intraoral testing for dentin hypersensitivity using a split-mouth-designed study were recruited for the study. Sensitivity was assessed by means of thermal and thermal/evaporative stimuli using VAS (visual analogue scale). After recording the baseline scores, the patients were randomly assigned to treatment with the desensitising agents -Clinpro XT varnish (Group I), Gluma power gel (Group II), Bifluoride 12 varnish (Group III) , GC Tooth Mousse plus (Group IV). After 10 minutes the patient’s responses was recorded. The follow-up was done after 1week and again after 2 weeks from the time of application of the agents. Results: All the four desensitizing agents were successful in relieving the sensitivity of the patients. Multiple group comparison between groups showed highly significant differences, GroupI showed maximum effectiveness followed by Group IV, Group II,& Group III after 10mins. The effectiveness of agents after 1 week was in the same order. However after 2 weeks it was seen that group I was most effective followed by group II & group IV, with Group III being the least effective. Conclusion: Dental professionals need to understand the causes of dentin hypersensitivity.Once a diagnosis has been made and the factors have been identified a treatment plan can be outlined to the patient for the treatment of dentin hypersensitivity.

Antibacterial surface properties of fluoride-containing resin-based sealants

Objectives The aim of the present study was to determine the antibacterial properties of three resin-based pit and fissure sealant products: Clinpro (3M ESPE), Embrace (Pulpdent), and UltraSeal XT plus (Ultradent). Methods The antibacterial effects of the sealants were tested in both an agar diffusion assay and a planktonic growth inhibition assay using Streptococcus mutans and Lactobacillus acidophilus. The materials were applied to paper and enamel disks in the former and on the side walls of 96-well microtiter plates on the latter. Results All materials showed either diffusible or contact antibacterial effects in the agar diffusion assays. The effect was diminished when enamel disks were used as substrate. In the planktonic growth inhibition assay, Clinpro had its effect reduced, but retained activity against both bacteria over time. L. acidophilus was more sensitive than S. mutans to UltraSeal. Embrace retained antibacterial activity against both bacteria over time. Conclusions Within the limitations of this in vitro study it can be concluded that all materials are capable of contact inhibition of L. acidophilus and S. mutans growth. Embrace has the longer lasting antibacterial activity when in solution, especially against S. mutans.
