Primary Teeth

The treatment of pulpal diseases in primary teeth represents a significant challenge in public health, particularly in emergency dental care settings, where factors such as limited clinical time, low child cooperation, and structural constraints directly impact treatment effectiveness. In these contexts, conventional pulpectomy using zinc oxide-eugenol (ZOE), although effective, may present operational limitations that restrict its large-scale applicability in public health systems. In this scenario, non-instrumental endodontic treatment (NIET), based on the concept of Lesion Sterilization and Tissue Repair (LSTR), has emerged as a simplified alternative. Among the available options, CTZ paste shows potential for single-visit application, reducing clinical time and technical complexity. This study aims to evaluate the clinical and radiographic non-inferiority of CTZ paste compared to conventional pulpectomy with ZOE in primary molars with pulp necrosis, with or without abscess or fistula, treated in emergency dental care settings. This is a randomized, pragmatic, controlled, non-inferiority clinical trial conducted at a single center, with clinical and radiographic follow-up at 3, 6, and 12 months. Participants will be allocated into two groups: (1) NIET with CTZ paste and (2) conventional pulpectomy with ZOE. Primary outcomes include pain resolution and absence of clinical signs of infection. Secondary outcomes include radiographic success, clinical time, child behavior (Frankl Scale), need for retreatment, and oral health-related quality of life. The findings are expected to provide robust evidence regarding the effectiveness of CTZ paste under real-world clinical conditions, contributing to the development of more accessible and effective protocols within public health systems, with the potential to expand access to conservative treatment and reduce early tooth extractions in pediatric dentistry.

The goal of this observational study is to evaluate the adaptation of occlusion and bite force after zirconia crown restoration in children with pulp-treated primary molars. The main questions it aims to answer are: How does occlusion adapt after placement of zirconia crowns? Does bite force change following crown restoration? Participants will: Undergo routine pulp treatment and restoration of primary molars with zirconia crowns. Have bite force and occlusal contacts measured using the T-Scan digital occlusal analysis system before and after crown placement.

The present study aims to evaluate the clinical and radiographic success of pulpotomy using 3Mixtatin versus pulpectomy using Metapex in primary molars with irreversible pulpitis in children aged 4 to 9 years.

This study will be carried out to evaluate and compare the clinical and radiographic effect of zinc oxide-ozonated olive oil (ZnO-OO) versus Modified Triple Antibiotic Paste (MTAP) as a Lesion Sterilization and Tissue Repair Technique in Primary Molars
