A Clinical Trial to Assess the Retention and Caries Preventive Effect of Resin Based Sealants Versus ART Sealants
This trial is active, not recruiting.
|Treatments||helioseal - f, art sealant|
|Sponsor||Dr. Praveen B.H|
|Collaborator||Kamineni Institute of Dental Sciences|
|Start date||March 2015|
|End date||November 2016|
|Trial size||180 participants|
|Trial identifier||NCT02408601, KamineniIDS|
Background and study aims:
The investigators are carrying out a clinical trial of two different sealant materials to compare the retentivity and decay inhibiting properties of the above said materials. it is a split mouth study, wherein the 2 sealant materials will be placed on the exactly opposite placed molars of 180 healthy school children in the age group between 7 - 10 yrs of age.
who can participate? school children in the age group between 7 - 10 yrs of age with non decayed contra lateral permanent 1st molars at a school in the southern part of India.
what does the study involve? over a period of 18 months, the retentivity and the decay preventing effects of these two sealant materials( RESIN BASED SEALANTS AND ART SEALANTS) will be clinically assessed by us.
possible benefits/ risks of participating in the trial the participants will be not be exposed to any kind of risks as it is a non invasive procedure the possible benefits may be preventing decay to the permanent molar in the long run
study start date/duration of the study? MARCH 2015 is the month wherein the sealant applications have started and expected to last till the Sept of 2016
funding? self funded study

|Description||Pits and fissures in the first molars are the most susceptible sites for dental caries in the permanent dentition and contemporary studies show specifically that 85% or more of the caries is nested in the above-mentioned sites . Thus, prevention of caries in these tooth sites is of crucial importance in keeping a sound permanent dentition. Sealing the pits and fissures of molars and premolars for prevention of dental caries was first introduced in the 1960s . It is now accepted as a highly effective method in preventing dental caries . Prominantly, there are basically two types of sealant materials..i.e resin based sealants which are flowable composite resins and Glass inomer based sealants. Reading through the literature, it is well understood that the resin based sealants are more retentive than the GIC based sealants mainly because the enamel surface is etched prior to the placement and it is dispensed through syringes, thereby it generally adapts well to the surfaces. GIC sealants are known to be equally effective when to comes to caries prevention, but generally are far less retentive than the resin based sealants. the main issue regarding the placement of resin based sealants is that it is a cumbersome procedure requiring strict isolation. Looking at a dental public health point of view, especially in a country like India, the use of resin based sealants at outreach centres will be a problem because of the lack of adequate infrastructure. To counter the limited applicability of resin based sealants in a field setting, the use of a high viscosity GIC sealant is advocated here. The high viscosity GIC sealant has a better compressive strength to take on the occulsal stress and thereby it is expected that the retention of the ART sealant (High viscous GIC sealant) using the ART technique (finger press technique) would be better than the conventional GIC based sealants. Till date, a very limited number of studies have been performed on the comparison between the ART sealant and the resin based sealant( gold standard) and thereby, this study has been conceived to assess the retentivity and the caries preventive effect of the above two systems. The null hypothesis states that there is no expected difference between resin based sealants and ART sealants Based on the statistical analysis, the sample size for this study has been estimated to be 180 subjects. ethical clearance has been obtained from the IRB of the dental school and informed consent obtained from all the participating subjects. This is a spilt mouth study, wherein on side, resin based sealants are placed and on the other side, the ART sealants are placed. All the participating 180 subjects do have a caries free permanent lower 1st right and left molars. The sealants are placed according to the manufacturer s instructions. after placements, the retention and the caries preventive effects are followed up progressively for a period of 18 months.|
