Experimental Research on Deep Carious Lesion Treatment of Molars

Carol Davila University of Medicine and Pharmacy40 enrolled

Overview

Maintaining dental pulp vitality is crucial for tooth preservation and functionality. Untreated dental caries may lead to pulp necrosis and infection, affecting children's growth and well-being. The first permanent teeth erupt around 6 years old. These are the first molars (FPM), which are frequently affected by caries, soon after their eruption. In the present application, our main goal is to determine whether two treatment groups (MTA and TheraCal) are long-term effective in preserving pulp vitality among children' FPM affected by deep caries.

Among the most frequently used materials for pulp capping are calcium hydroxide, mineral trioxide aggregate (MTA), and, more recent, TheraCal. All of them are biocompatible and induce the formation of coronal hard tissue barriers (tertiary reparative dentin). Calcium hydroxide, considered for a long time the gold standard of direct pulp capping materials, has excellent antibacterial and remineralisant properties; however, it lacks adhesion, especially at moist dentin, and reparative dentin is less homogenous. MTA proved to stimulate protective dentin bridge formation without inflammatory changes and least necrosis. It is also moisture tolerant, but it is more expensive, has poor handling characteristics and slow setting time. TheraCal bonds to deep moist dentin, has strong physical properties, no solubility, high radioopacity and higher calcium releasing abilities than MTA or calcium hydroxide.

Outcomes

Primary Outcomes

Clinical pulpal survival rate

Pulpal survival is defined by positive response without lingering sensation to the cold test, absence of clinical signs and symptoms, and no apical radiolucency on the periapical radiograph.

Time frame: 20 months

Secondary Outcomes

Incidence of apical root maturation (apexogenesis)

We will investigate the treatment effect on apexogenesis in children who had incomplete root formation at the beginning of the study and preserve their pulp vitality at the end of the study. The outcome will be compared radiographically with apical maturation in molar pairs (healthy contralateral molar, where applicable).

Time frame: 20 months
