Abstract
The continuous research of dental materials resulted in the evolution
of bioactive materials over the past three decades from just relatively
specialized, highly biocompatible but low strength materials to the currently
known products with advanced formulations for expanded clinical uses in
restorative dentistry.
BiodentineTM was one of those products. It is classified as a calcium
silicate based material and is considered to be the newer sister product of
MTA which somehow is categorized similarly.
The use of BiodentineTM in pediatric dentistry was just vague prior to
the initiation of this study. Its similarity to MTA was a motive for us as
researchers to investigate its performance as a pulp dressing in primary teeth.
Moreover, partial pulpotomy technique in primary molars was revisited
using BiodentineTM.
The current study was composed of two corresponding, in vivo and in
vitro studies. In the in vivo study, a total of twenty seven patients between
ages of 4-7 years old were selected from the outpatient clinic of Pediatric
Dentistry Department, Faculty of Dentistry, Ain Shams University from
which 45 teeth were recruited following the inclusion criteria adopted by the
study.
Teeth were randomly allocated into four groups and received
treatment accordingly.
group (I) -BiodentineTM Partial Pulpotomy
group (II) -Calcium Hydroxide Partial Pulpotomy
group (III)-Formocresol Complete Pulpotomy
group (IV)-BiodentineTM Complete Pulpotomy Follow up appointments were given at 6 months, 12 months, and 18
months to evaluate the clinical and radiographic success according to the
criteria proposed by Agamy et al. and Vargas et al. 98, 102 A binary scoring
system was employed to record any failures.
Statistical analysis of the tabulated scores was performed using
Kruskal–Wallis followed by Mann-Whitney U, revealing the superiority of
BiodentineTM in both complete and partial pulpotomy in primary teeth versus
FC complete pulpotomy and CH partial pulpotomy. Steep deterioration in
the clinical performance of the CH partial pulpotomy group was detected at
6, 12, and 18 months.
In the in vitro study, a total of fifteen sound human premolars which
were freshly extracted for orthodontic reasons were collected from the
Department of Maxillo-facial and Oral surgery, Faculty of Dentistry, Ain
shams University and were utilized in this study. Teeth were divided into
two groups and restored by BiodentineTM and glass ionomer. They were
stored in distilled water for 24 hours and then dyed using 1% methylene blue
solution.
Teeth were sectioned bucco-lingually and examined for microleakage
implementing Ghasemi et al. criteria, using a stereo light microscope.103
Scores were tabulated and statistically analyzed.
The results revealed that there was no significant difference between
both BiodentineTM and conventional glass ionomer as a dentine replacement
material.
