Background: Pulpotomy as a minimally invasive pulp therapy technique is the treatment of choice for carious pulp exposures, however many pediatric dentists perform pulpectomies in vital primary incisors. The aim of this split mouth randomized controlled study was to compare formocresol pulpotomy and zinc-oxide and eugenol pulpectomy in the treatment of vital pulp exposure in primary incisors.

Methods: Contralateral pairs of incisors were randomly assigned to receive pulpotomy or pulpectomy in children aging from 18 to 66 months old and were followed up for 12 months.

Results: 39 pairs of incisors were included. Clinical and radiographical success rates showed no statistical significant difference (p = 1, p = 0.8 respectively). Relative risk measures for clinical success rates (RR = 1.03, 95%CI 0.87 to 1.23) and for radiographic success rates (RR = 1.03, 95%CI 0.83 to 1.29) with CIs including number one showing no difference between the two groups. The Survival rate using Kaplan-Meier survival analysis score showed 82% for pulpotomy and 74% for pulpectomy at 12 months (P = 0.2).

Conclusions: Both pulpotomy and pulpectomy techniques can be used successfully in the treatment of carious vital pulp exposure in primary incisors.

Trial Registration: The trial was retrospectively registered in Clinicaltrials .gov with this identifier NCT05589025 on 21/10/2022.

Introduction: Vital pulp therapy (VPT) aims to preserve dental pulp after injury and has gained significant popularity due to advancements in materials and understanding of pulp biology. While bibliometric analyses are common in various fields, none have been conducted specifically for the 100 most-cited articles on VPT.

Materials And Methods: This bibliometric study analyzed the 100 most-cited VPT papers using data from Web of Science (WoS-CC), Scopus, and Google Scholar.

Background: Dental trauma can cause damage to the pulp tissue in immature teeth. Revascularization therapy is a possible option in the treatment of non-vital, immature permanent teeth with a history of trauma. The aim of this prospective study was to evaluate the radiographic and clinical results of immature teeth with a history of trauma treated by regenerative endodontic procedures and mineral trioxide aggregate apexification techniques.

(β-ketoacyl-acyl carrier protein (ACP) synthases II), (fatty acid thioesterases), (stearoyl-ACP desaturase), and (fatty acid desaturases) are the vital gene families involved in fatty acid (FA) synthesis in L. However, information on the number and location of these genes and which ones are key to the formation of FAs in fruit seeds and pulp was not complete. Our study aimed to solve this issue using the available genomic sequences and transcriptome data that we obtained.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth.
