Abstract
BackgroundThe success of pit and fissure sealants is directly related to their retention. The purpose of this study was to assess and compare the retention of pit and fissure sealants placed using acid etch alone and a combination of air abrasion and acid etch techniques.Material and Methods50 subjects aged 6-8 years were included in the study. 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. Retention of sealants was checked using Simonsen’s criteria of sealant retention after three and six months of sealant application.ResultsThere was no significant difference in retention of sealants in Group A and Group B (p<0.05) after three and six months follow up. The difference in sealant retention in primary and permanent molars was not significant (p>0.05). Maxillary molars showed superior retention compared to mandibular molars, which was statistically significant at both three and six months (p<0.05).ConclusionsCombining air abrasion pretreatment with subsequent acid etching did not result in statistically significant difference in sealant retention compared to acid etching alone in both primary and permanent molars after 3 and 6 months follow up. An additional air abrasion pretreatment step can be avoided in pediatric patients when placing sealants and the procedure can be completed faster with better behavior management using acid etching alone. Key words:Pit and fissure sealant, acid etching, air abrasion.
Highlights
Prevention of oral diseases is preferable to treatment and is the key method of achieving cost effectiveness for oral health improvement programs
The protocol for sealant placement using the acid etching technique (Group A) and acid etching with air abrasion pretreatment (Group B) was as follows: 1. ISOLATION OF TEETH Isolation was achieved with the help of rubber dam for all four quadrants
Within the limitations of this study, it may be concluded that: 1. Combining air abrasion pretreatment with subsequent acid etching did not result in statistically significant difference in sealant retention compared to acid etching alone in both primary and permanent molars after 3 and 6 months follow up. 2
Summary
Prevention of oral diseases is preferable to treatment and is the key method of achieving cost effectiveness for oral health improvement programs. 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 purpose of this study was to assess and compare the retention of pit and fissure sealants placed using acid etch alone and a combination of air abrasion and acid etch techniques. 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. Conclusions: Combining air abrasion pretreatment with subsequent acid etching did not result in statistically significant difference in sealant retention compared to acid etching alone in both primary and permanent molars after 3 and 6 months follow up. An additional air abrasion pretreatment step can be avoided in pediatric patients when placing sealants and the procedure can be completed faster with better behavior management using acid etching alone
