Abstract:Aim: The aim of this study was to evaluate the effect of various pulpotomy materials on the fracture resistance of pulpotomized primary second molars. Materials and Methods: Hundred extracted primary second molars were randomly divided into five groups as follows: Control group (had no treatment), Zinc oxide-eugenol group (pulpotomized with zinc oxide eugenol), ProRoot MTA group (pulpotomized with ProRoot MTA), RetroMTA group (pulpotomized with RetroMTA), and Biodentine group (pulpotomized with Biodentine).

Background
Endocrown in pediatric dentistry was rooted in the fundamental principles of preserving healthy dental tissues, leveraging contemporary adhesive methodologies.
Aim
This research aimed on assessing and comparing the fracture resistance of pulpotomized primary molars when rehabilitated with zirconia crowns and two distinct types of endocrowns, namely E-Max and Brilliant Crios.
Methods
The study involved thirty, anonymized, freshly extracted second primary molars that underwent pulpotomy. These teeth were then evenly divided into three groups, each consisting of ten specimens: the zirconia crown, the E-Max endocrown, and the Brilliant Crios endocrown groups. Post-pulpotomy, the teeth were prepared for their respective restorations. Subsequent to this preparation, the zirconia crowns, E-Max endocrowns, and Brilliant Crios endocrowns were secured. To evaluate the fracture resistance using a computer-controlled testing machine (Instron), a progressively increasing load was applied to each group until fracture occurred. The gathered data were then analyzed for outliers and subjected to normality testing using the Shapiro-Wilk and/or Kolmogorov-Smirnov tests, with a significance threshold set at 0.05.
Results
There was no statistically significant difference in fracture resistance of pulpotomized primary molars among lithium disilicate (E-Max) group (mean=1367.59N), Brilliant Crios group (mean=1349.73N) and zirconia group (mean=1240.82N).
Conclusion
Endocrowns can be considered a promising restoration for pulpotomized primary molars.
