Influence of Isolation Methods on Retention of Pit and Fissure Sealants in Young Permanent Teeth based on Simonsen’s Criteria: A Randomised Clinical Trial
Introduction: Pit and Fissure Sealants (PFS) are chemicallyactive liquid materials that are introduced into the occlusal surface of caries-susceptible teeth. These form a micro mechanically bonded, protective layer preventing access to caries-producing bacteria, from rest of the oral environment....

| Summary: | Introduction: Pit and Fissure Sealants (PFS) are chemicallyactive liquid materials that are introduced into the occlusal
surface of caries-susceptible teeth. These form a micro
mechanically bonded, protective layer preventing access to
caries-producing bacteria, from rest of the oral environment.
Aim: To evaluate the retention of PFS placed on young
permanent teeth using two isolation methods.
Materials and Methods: This clinical study was carried out
in the Department of Paediatric and Preventive Dentistry, at
Narayana Dental College and Hospital, Nellore, Andhra Pradesh,
India. One hundred Permanent First Molars (PFM) from 25
healthy, cooperative children in the age group of 6-9 years were
assigned by block randomisation into two groups (isolation
type); each group containing the upper and lower PFMs of the
right and left side receiving two different treatment modalities
(split-mouth design). In Group I (n=50 teeth), the teeth received
sealant with rubber dam isolation, and in Group II (n=50 teeth),
with cotton roll isolation. The sealant was applied to all the PFMs
as indicated. All the teeth were evaluated using Simonsen’s
criteria at regular intervals of 3, 6, and 12 months. The data
collected were subjected to statistical analysis using the SPSS
statistical package (version 17) and statistical significance was
set at 0.05. The difference in the retention of PFS with the two
isolation methods was analysed using the Chi-square test.
Results: After 12 months, the marginal integrity rate for sealants
placed with a rubber dam and cotton roll isolation were 75%
and 64%, respectively. The results were better in Group I than
in Group II, although there were no statistically significant
differences with respect to marginal integrity, discolouration,
and anatomical failure.
Conclusion: Retention of PFS in young permanent teeth was
better with rubber dam than cotton rolls for isolation, though the
results were not statistically significant. |
