Pit and fissure sealant application updating the technique spongebob sex games online
Sealants are effective caries preventive agents as long as they remain bonded to teeth (4).The different methods recommended to improve sealant retention include cleaning of the occlusal surface prior to sealant placement with hydrogen peroxide, pumice prophylaxis, air polishing, mechanical preparation of fissures and air abrasion.Teeth were subsequently rinsed with water for 20 seconds and then air-dried using three way syringe.Both primary and permanent molars were etched for 15 seconds.(b) For Group B (Acid etch with air abrasion pretreatment): Air abrasive system with 50 micron alumina particles was used for 5 seconds at 5 mm distance (as per manufacturer’s instructions) from tooth surface with predetermined angle of 1380 (fixed nozzle in Standard model) and air pressure of 60-80 lbf/pol2, followed by etching as done for Group A.3.However, marginal leakage studies have shown that air abrasion alone is not as effective as air abrasion coupled with acid etching in preventing microleakage (7).An uncertainty for the best enamel surface pretreatment before sealant application still exists even after years of research studies.After suitable selection of rubber dam clamps, teeth were isolated either arch wise or quadrant wise as per convenience and cooperation of the child.2.
However, concern has been expressed that the traditional acid etch technique for sealant placement does not allow for complete cleaning of the pits and fissures prior to sealant placement (6).
This study attempts to evaluate and compare the efficacy of two enamel surface pretreatment techniques - Acid etching alone or combination of air abrasion followed by acid etching technique.
The present study is a longitudinal experimental study carried out after obtaining prior approval from the Ethical Committee of the Institution.
Primary second molars and permanent first molars were sealed in all four quadrants using split mouth design.
The right maxillary and mandibular molars (Group A) were treated by acid etching alone while the left maxillary and mandibular molars (Group B) were pretreated with air abrasion followed by acid etching before application of pit and fissure sealant.
