Abstract

Purpose: To compare the degrees of marginal microleakage undergone by different intermediate materials used for provisional restoration in indirect pulp treatment: glass ionomers (KetacTM Fil Plus (3M ESPE), KetacTM Molar Easy Mix (3M ESPE), Fuji IXTM GP (GC)) and zinc oxide eugenol. Materials and methods: Twenty young permanent premolars, extracted for orthodontic reasons, were prepared by creating Class II cavities and then divided into four groups according to the material used for pulp capping. The materials were applied following the manufacturers' instructions and stained with methylene blue at 2% to evaluate microleakage. Results: Results were evaluated applying variance analysis (ANOVA). It was found that glass ionomers showed better outcomes than zinc oxide eugenol, with Fuji IXTM GP and KetacTM Molar Easy Mix producing the best results. Conclusion: For indirect pulp capping, glass ionomer is a favorable material for reducing one of the main causes of treatment failure - microleakage - although there are differences between brands.

Highlights

Dental caries is without doubt one of the major challenges in dentistry
On the basis of the microleakage criteria established, it was found that glass ionomers showed the most favorable results in comparison with teeth obturated with zinc oxide eugenol. (Figures 1 & 2) In particular, Fuji IXTM and GP KetacTM Molar Easy Mix produced the best results. (Graph 1)
Different studies vouch for the success of this technique in primary dentition [9,10].A retrospective study by Al Zayer et al [11] found that indirect pulp treatment (IPT) of posterior primary teeth is a good alternative to vital pulp therapy

Summary

Introduction

Dental caries is without doubt one of the major challenges in dentistry. Its occurrence has numerous repercussions that all exert an influence over the integrity and development of the affected tooth. The dentist’s main objective is to maintain the vitality and function of the dental pulp [1]. Vital pulp therapy includes the following treatment possibilities [1,2]: Protective bases.
