| 总结: | Introduction: Ferric sulfate and Laser has been used for conventional pulpotomy therapy. Clinical and radiographic evaluation
of pulpotomies using these have been done in numerous studies
but there exists few studies analysing the histologic response of
pulp to laser and ferric sulfate.
Aim: The aim of the study was to evaluate and compare histological changes seen in the pulp following ferric sulfate and laser
pulpotomy and compare these effects.
Materials and Methods: This was a single blind in vivo study,
consisting of 24 primary teeth. The teeth were randomly divided
into two groups based on the material to be used and subgrouped
based on the time period (30 and 45 days) of evaluation.
The teeth were extracted after the study period and tissue
processing done and subjected to Haematoxylin and Eosin
staining procedure. The tissues were evaluated for dentin bridge
formation, quality of dentin formation in the bridges, location of
dentin bridges, tissue reaction to the material, inflammatory cell
response and necrosis. The statistical analysis was done using
SPSS 20.0 software. Intragroup comparisons of the observed
values were analysed using Chi-square test.
Results: Statistical analysis revealed non-significant difference
between the two materials to produce reparative dentin and
also the quality of dentin bridges formed in both the groups
during both the observational periods. Majority of the samples
in both ferric sulfate and laser group exhibited dentin bridge
at the interface of the exposed pulp, bridging or attempting to
bridge the site exposed to the pulpotomy material. The ability
of the materials to evoke a foreign body and inflammatory
cell responses in the pulpal tissue was not significant. All the
samples of both the groups showed signs of necrosis with two
samples of laser group showing severe necrosis in 45 days
period. The difference between the groups in 30 days group
was statistically significant.
Conclusion: Laser and ferric sulfate are found to be able to
initiate dentin bridge at the interface between the pulp and the
material but the quality of bridge formed was better in laser
group. Laser group showed more macrophage infiltration,
inflammatory cell infiltration and areas of necrosis compared to
ferric sulfate group though not statistically significant |
