Pulp Inflammatory Markers and Outcome of Pulpotomy

Overview

This is a prospective clinical study that aims to investigate the level of inflammatory mediators in the inflamed dental pulp and its potential relationship to the outcome of full pulpotomy in mature permanent teeth with carious pulp exposure. Pulp blood samples from the teeth will be collected during treatment, MMP9 levels will be recorded using Elisa kits. The teeth will be restored and followed up at 1 week, 6 months, 1, and 2 years. The teeth will be assesses both clinically and radiographically. The procedure will be success if the tooth is asymptomatic clinically and with normal periapical findings. The relationship between MMP9 level and success of treatment will be investigated.

Dental caries is one of the most common chronic diseases of adults and children. If left untreated, the disease can have a wide range of dental, medical, social, and quality of life consequences, such as pain, infection, early tooth loss, and loss of self-confidence. Full pulpotomy is a vital pulp therapy procedure that involves the removal of the coronal pulp to the levels of canal orifices followed by achieving hemostasis and placement of a biocompatible capping material. Full pulpotomy has been proved to be a promising alternative treatment option to the conventional root canal treatment in cariously exposed molars with either diagnosis of reversible or irreversible pulpitis. Clinically, diagnosing the actual histopathological status of the inflamed pulp is challenging and is an empirical guess based on the results of sensibility testing and patients' symptoms. In recent years there has been an attempt to investigate the level of inflammatory mediators in the pulp, with an attempt to develop a chairside diagnosis tool that will help better in diagnosing the state of the pulp; and therefore, predict the outcome of treatment procedures. In recent years matrix metalloproteinases (MMPs) have been increasingly studied for their role in the diagnosis of dental inflammatory processes. Several studies evaluated the correlation between inflammation of the dental pulp and the levels of MMPs (MMP-1, -2, -3,-8 and -9), in addition to other molecular markers like interluekins and prostaglandins. However, the use of concentrations of MMPs in the pulpal blood as a marker to differentiate between reversible and irreversible pulpitis has not been thoroughly investigated yet. The aim of the study is to investigate the inflammatory mediators' level in inflamed pulps and to assess its relation to the outcome of full pulpotomy in carious teeth with symptomatic pulpitis.
