Abstract
This randomized clinical trial aimed to evaluate the patient’s preference and chair time needed during pit and fissure sealant placement under three isolation techniques (Isolite system, rubber dam isolation, and cotton roll isolation). Participants, aged 6–15 years and requiring four sealants on the first or second permanent molars, attending the pediatric dental clinics at King Saud University in Saudi Arabia were enrolled according to the inclusion criteria. Each participant received sealants on three random first or second permanent molars using three isolation techniques. The time required for sealant placement was recorded for each technique. Following sealant placement, an interview-based questionnaire was administered to the participants to evaluate their preference regarding the isolation techniques. Forty-eight children (23 male and 25 female) with a mean age of 8.58 ± 1.93 years participated in this study. The mean chair times were 248.14, 255.89, and 243.29 s for the Isolite system, rubber dam isolation, and cotton roll isolation, respectively. Approximately 79% of participants considered cotton roll isolation to be the most comfortable, whereas approximately 71% were significantly less likely to use rubber dam isolation again. In conclusion, there were no significant differences in sealant placement time among the three isolation techniques. However, cotton roll isolation was the technique that was most preferred by the participants.
Highlights
Dental caries represent one of the most common chronic and multifactorial diseases affecting the human population [1]
The overall time taken for each type of isolation technique plus sealant placement was compared
It was observed that cotton rolls took the least amount of time, while rubber dams took the longest amount of time (Table 1)
Summary
Dental caries represent one of the most common chronic and multifactorial diseases affecting the human population [1]. Eighty to ninety percent of dental caries are present in the pits and fissures of the permanent teeth in pediatric patients [2]. Several epidemiological studies have indicated that caries in children are considered critical and that the incidence of dental disease among children in Saudi Arabia is increasing [3]. The prevalence of dental caries is considered high, affecting 69%, 73%, 62%, and 85% in Riyadh city, Dammam city, Makkah city, and Abha city, respectively [4,5,6,7]. There is a need to limit pathogen growth and caries activity by prevention rather than cure [3]. Sealants have been widely discussed since their development due to their ability to inhibit the growth of bacteria by eliminating food particle accumulation in these fissures [8,9]
