5. Study Description

Brief Summary
The purpose of this study is to compare the clinical and radiographic success of a new injectable, fast setting bioceramic root repair material (BC RRM) putty with mineral trioxide aggregate (MTA) in pulpotomy procedures of primary teeth. The null hypothesis (H0) is that there is no difference in the clinical and radiographic success between the TotalFill® BC RRM™ Fast Set Putty and Produits Dentaires™ (PD™) MTA WHITE when used as a pulp dressing in pulpotomies of primary molars.
Detailed Description
Dental Caries is the most common chronic disease worldwide and the most common disease of childhood, with increasing prevalence in many countries, including Egypt. About 70% of Egyptian children have some untreated caries experience. This percentage was also reported by an unpublished nationwide survey funded by the World Health Organization (WHO). Dental decay is the primary cause for oral pain and tooth loss. Toothache as a result of untreated caries is persistent and often severe. In children, the prevalence of dental pain ranges from 5% to 33% and increases with caries severity, child age and decreasing economic status. Untreated caries in children can lead to pain, sepsis and affect the quality of life of children and their families, such as lost school days, family disruption, and the need for costly dental treatment. Tooth decay has a multifactorial nature of occurrence. The carious process is a result of an imbalance between pathogenic factors, namely the high frequency of fermentable sugar intake and the increase in acid-producing bacteria, which outweigh host protective factors in the oral cavity favoring demineralization of the tooth structure. This on-going process progresses more rapidly in primary compared to permanent teeth which may be attributed to the different anatomical characteristics between them. Thinner enamel and dentin as well as larger pulp and higher pulp horns make deciduous teeth more vulnerable to degradation of hard tissues and pulpal affection. Approximately 75% of deep carious lesions were found clinically with pulp exposure. The deciduous teeth are important for mastication, speech, esthetics as well as for the preservation of arch integrity and space for the permanent successors. Hence, pulp therapy is the appropriate alternative to extraction for pulpally affected primary teeth in most clinical situations. Depending on the extension of the carious process, different pulp treatment modalities are available, pulpotomy being the most common among them with a high success rate of 82.6%. Complete pulpotomy involves the complete removal of the inflamed and/or infected coronal pulp tissue and the application of a medicament to the pulp chamber or radicular pulp remnants allowing healing of the radicular pulp tissue. For decades, formocresol had been the gold standard material for pulpotomy procedures in primary teeth until mineral trioxide aggregate (MTA) was introduced. According to several systematic reviews and meta-analysis, MTA presents superior performance and higher success rates compared to other materials in pulpotomy of primary teeth. MTA pulpotomy has become a safe and biocompatible treatment alternative with success rates comparable to formocresol pulpotomy. Although MTA has been recently considered the gold standard material for pulpotomy procedures, some drawbacks such as poor handling and long setting time are challenging when used as pulpotomy dressing in primary teeth of children. Thus, the evaluation of the clinical and radiographic performance of other materials such as a bioceramic root repair material in a convenient injectable form with faster setting time is of paramount importance for the management of dental caries in the pediatric patient. Evidence is lacking as to the effectiveness of bioceramic materials as pulp dressing in the primary dentition and to their clinical or radiographic success compared to other materials. Different bioceramic root repair materials (BC RRM) have been used in the adult population. To our knowledge, there are no studies evaluating the use of BC RRM in pulp therapy of deciduous molars. Since MTA has been recently advocated to be the gold standard in pulp therapy, it is chosen as the comparator in the control group. A two arm, parallel group, randomized controlled trial, with 1:1 allocation ratio to either study group or control group, is the study of choice to test the null hypothesis and answer the research question. The study will be conducted at the outpatient clinic of the department of Pediatric Dentistry and Dental Public Health, Faculty of Dentistry, Ain Shams University. This research will be reviewed by the Research Ethics Committee and Institutional Review Board, Faculty of Dentistry, Ain Shams University. A verbal as well as a written consent will be obtained from the caregivers of the participants after explaining the objectives of the study and assuring complete confidentiality of data. All caregivers and participants will be informed that they have the right to withdraw from the study at any time. Moreover, participants 6 years and older will be requested to sign an assent form after an age appropriate explanation of the trial procedures and their objectives. All consent and assent forms are translated into Arabic. A power analysis was designed to have adequate power to apply a statistical test of the research hypothesis (null hypothesis) that there was no difference between the clinical and radiographic success between the bioceramic root repair material and Mineral Trioxide Aggregate when used as a pulp dressing in pulpotomies of primary molars. By adopting an alpha (α) level of 0.05 (5%), a beta (β) level of 0.20 (20%) i.e. power=80%, and using an effect size (w=0.430); the predicted sample size (n) was found to be a total of (52) teeth; i.e. (26) for each group and (13) for each subgroup. Sample size calculation was performed using G*Power version 3.1.9.2.44 The sample size was increased by 15% to (30) primary molars per group, i.e. (15) molars per subgroup and (60) in total to compensate for drop-outs. The study interventions are expected to be conducted from 2020 until 2022. After informed consent, baseline clinical and radiographic assessment will be obtained and recorded in the patient's examination sheet. Enrolled participant's tooth will be then randomly allocated to the experiment or control intervention group. Participant will be recalled for follow up assessments at 1, 3, 6 and 12 months. A 14 day window, defined as 7 days before and 7 days after the due date, will be available to complete the 1 and 3 month follow-up evaluations and a 28 day window, defined as 7 days before and 21 days after the due date, will be available to complete the 6 and 12 month follow up evaluations. Participants' data will be recorded in an examination sheet and stored as hard copy files. Patients' information will be regarded as confidential and will never be revealed at all times. This will be ensured by assigning codes to participants' teeth undergoing intervention. Several attempts will be made calling participants on the phone for clinical and radiographic follow up appointments at 1, 3, 6 and 12 months. Patients who fail to show up at the follow up examinations, within the defined follow up windows, will be automatically excluded from the study. Patients who are no longer willing to continue in the study have the right to quit at any time and will be offered to continue dental treatment at the department's outpatient clinic. All data will be collected, tabulated, summarized and statistically analyzed using the Statistical Packages for Social Sciences (SPSS) software. Regular unannounced audits by the Research Ethics Committee, Faculty of Dentistry, Ain Shams University are expected as to ascertain that protocol guidelines are followed throughout the study. In addition to the study supervisors, independent staff members and clinic supervisors of the Department of Pediatric Dentistry and Dental Public Health, Ain Shams University monitor clinical performance to ensure adherence to best practice. MTA and BC RRM have been shown to have no adverse effects on healthy patients. On the contrary, they have been shown to be biomimetic and biocompatible when used for endodontic procedures in adults. Failure of pulp therapy and abscess formation might occur as with all materials used in pulpotomies to this date. Short term follow up will avoid the occurrence of any serious condition and will allow its instant treatment. Any adverse event will be recorded and managed promptly. Furthermore, in case of consistent failures, the use of the experimental material will be stopped and patients will be treated with another modality.

Masking
ParticipantOutcomes Assessor
Masking Description
Participants will be blinded to which group they are assigned to. Both materials used have the same white color and any labels on syringes will be hidden with appropriate wrap. Teeth treated will be assigned codes so that outcome evaluators at follow up appointments are blinded. Furthermore, baseline clinical and radiographic findings of sound teeth as well as after pulp therapy and stainless steel crown placement will not reveal the material being used at the intervention, since the stainless steel crown obscures the view clinically and radiographically. On the other hand, the operator/primary investigator cannot be blinded as she is already familiar with the nature of the materials used and their different modes of application. For statistical analysis, codes will also assure blinding and confidentiality.
