Bioactive and biocompatible cement as a single element in pulpotomy of deciduous teeth: a randomized clinical trials

Abstract

Objective: Pulpotomy in deciduous teeth maintains the integrity and health of deciduous teeth and supporting tissues until a permanent tooth has erupted. PBS HD CIMMO® cement was evaluated in deciduous teeth pulpotomies as base material and restoration. A randomized clinical trial was performed Methods: This study was approved by the Ethics Committee of (Universidade Vale do Sapucaí) UNIVÁS with Certificate of Presentation for Ethical Consideration, protocol number is: 1.771.929. 60 deciduous molar teeth from 32 healthy children were selected. These teeth were divided into two groups: G1 with 30 teeth, in which the classictreatment with formocresol was used, and G2 with 30 teeth, in which PBS HD CIMMO® cement was used as base and simultaneous final restoration. The evaluation was performed 12 months after the intervention through clinical and radiographic exams. Fisher’s exact test was performed to correlate the clinical and radiographic aspects in both groups Results: There was no significant difference (p= 0.090) in the clinical-radiographic evaluation. PBS HD CIMMO® cement is option to be used as a single element in pulpotomies of deciduous teeth Conclusion: Longitudinal studies should be performed in order to demonstrate a significant association between these groups. The study was enrolled in clinical trials (clinical trials.gov) with registration NCT03200938.

Dental Cavity Lining, Composite Resin and Bioceramic: Randomized Clinical Trial

“…The advent of biological cements signaled a new era in dentistry. These cements are biocompatible and bioactive alternatives for use in procedures where the conventional technique is limited [10][11][12] . Bioactive cements do not have toxic components in their constitutions, such as those found in HEMA and TEGDMA adhesive systems [24][25] .…”

“…Recent studies have determined the development of biological cement with the same base as MTA (Mineral Trioxide Aggregate) and Biodentine®, used in Endodontics and considered bioactive, as they provide ionic bonding with dentin, regenerating the dentin tissue, establishing themselves as a base, previous to composite resin restoration, preventing the negative action of adhesive systems that, in conventional techniques, are installed directly on the pulp walls of cavity preparations [10][11][12]14] .…”

“…The results of this study showed that the rehabilitation occurred due to the cement's properties: biocompatibility and bioactivity. CIMMO HD® was considered an option to be used as a single element in pulpotomies of primary teeth [12] .…”

“…A patent was filed at the National Institute of Industrial Property -INPI, (BR1020170227480) 2017. It is currently marketed by Empresa MJS Ltda [11][12][13] .…”

“…Attributes that define it as a perspective for material to be used as pulp protection in permanent tooth restorations. The singularities of this cement are the requirements that endorse this proposal: compressive strength, bioactivity that determines ionic bonding with dentin, providing the formation of a dentin/cement monoblock and making the environment inhospitable to microbial proliferation [10][11][12][13][14] .…”
