Comparative evaluation of marginal integrity of glass ionomer and resin based fissure sealants using invasive and non-invasive techniques: An in vitro study.

Background: Occlusal surfaces of the molars are highly susceptible to dental decay. Pit and fissure sealants are one of the best methods of preventing fissure caries. The main problem encountered is microleakage leading to deterioration of material and increased possibility of the development of secondary caries. Aims: To assess and compare the marginal integrity of glass ionomer (Fuji VII) and resin based (Clinpro) fissure sealants using invasive and non-invasive technique. Setting and Design: Experimental in-vitro study. Materials and Methods: An in-vitro study was conducted on 40 healthy, extracted premolars. The teeth were divided into 4 groups. Group I: Clinpro-invasive technique, group II: Clinpro-non-invasive technique, group III: Fuji VII-invasive technique, group IV: Fuji VII-non-invasive technique. Sealants were applied and subjected to an evaluation under SEM (scanning electron microscopy) for the width of the marginal gap. ANOVA (analysis of variance) and Duncan's multiple range tests were used for the statistical analysis. Results: The mean width of the marginal gap was 0.4089 μm in group I as compared to 3.0485 μm in group III; and the difference was statistically highly significant (P<0.001). In non-invasive technique, Clinpro and Fuji VII showed a mean marginal gap width of 0.4486 μm and 3.0485 μm, respectively. This difference was statistically highly significant at a P<0.001. There was no statistically significant difference in the mean widths between invasive and non-invasive techniques. Conclusion: Clinpro performed better in terms of marginal adaptation than did the Fuji VII sealant. The techniques (Invasive and non-invasive) does not influence the marginal integrity significantly.

New Trends In Treatment of Dental Carries In Outreach Programme - Carisolv.

Dental caries is a global disease that affects almost everyone. The presence of untreated (unfilled) carious lesions is quite common in rural areas among school going children. Poor awareness about oral health, lack of dental manpower, lack of required infrastructure and lack of political will are some possible reasons which have contributed to this picture. Conventional caries treatment is carried out with a high speed hand piece to gain access to the lesion and low speed hand piece to remove caries. This is found to be unpleasant by many patients. The new technique chemo-mechanical caries removal more documented alternative to traditional drilling. This compendium is about Carisolv a chemo-mechanical system for non-invasive, gentle dentine caries removal based on biological principles through the use of an active gel and special hand instruments that preserve healthy tissue and increase patient comfort. Carisolv gel is applied to the caries affected area of the dentine where it softens the diseased portion of the tooth. Healthy tissue is preserved. The softened carious dentine is removed with special Carisolv instruments and filled with adhesive material (i.e GIC) the treatment is quick and effective. Many patients and dentists call it “a silent revolution”. Clinical studies have shown that Carisolv reduces or eliminates pain in association with caries removal. The reduced need for local anesthesia and drills also lead to minimized post-operative pain or discomfort. All these aspects prompt more patients treated with Carisolv to return to the dentist it caries reappears. A quick review of dentine caries will clarify the requirements of an effective, chemo-mechanical caries removal system.

Oral Health Insurance In India.

Comprehensive Dental Insurance in India is non-existent entity Dental insurance is one of the major areas of medical insurance in the western world. Almost all the developed countries in the western hemisphere have a substantial population of their covered under the scheme of dental insurance. As a part of the medical coverage, dental insurance in India though is yet to be widespread. However, in keeping with the increasing awareness of the need for dental insurance and coverage, the process has started. More and more people today are opting for insurance in India. Similarly, new and new policies are being framed by the medical insurance companies in India who offer the policy of dental insurance also. Dental awareness in the Indian population continues to be low, thus reflecting on the priorities of seeking regular dental care. Dental insurance thus has a large untapped market and its high time that more focus be given towards this potential by the insurance regulator, service providers and professional bodies. The present article is an attempt to focus on the available schemes on Dental Insurance in India.
