    Abstract: Introduction : Denticles are mineralized formations found in the dental pulp of deciduous and permanent dentition. Topo-graphically, they can be classified as free, adjacent, or intratissular. Denticles rarely occur; however, their presence is considered clinically relevant due to the difficulties they cause during endodontic treatment. The aim of this study was to describe clinical cases of denticles located in the tooth pulp chamber. Various methods for their removal are also discussed. Emphasis was placed on the diverse appearance of pulp stones in microscope-captured images and on the necessity of maintaining appropriate clinical procedures for highly specialized endodontic treatment, such as working with rubber dams and magnification, to avoid serious complications. Materials and methods : Four cases of molar teeth with suspected intraventricular denticles were subjected to specialised endodontic treatment. Removal procedures were performed in aseptic conditions after dental dam placement and with the use of a dental operative microscope. To remove denticles, carbide long shank rose burs, Munce Discovery Burs, and an ultrasonic device with tips for finishing canal access and locating their orifices were used. Following preparation of a straight line access, the canals were chemically and mechanically cleaned and shaped according to accepted standards of modern endodontics. After obturation of the canal system, control radiographs were performed. Results : During all treatments, the denticles were removed completely, allowing further preparation and obturation of the entire canal system. Conclusions : Removal of denticles from the pulp chamber is a complicated, difficult procedure, requiring knowledge of the anatomy of the root canal system, professional operation skills, magnification of the operating site, and appropriate equipment. Such preparation allows clinicians to avoid potential complications such as perforation and/or excessive weakening of the tooth structure due to excessive removal of hard tissues.

    Abstract: Background and objectives: Pulp stones are hard tissue structures formed in the pulp of permanent and deciduous teeth. Few studies have evaluated their morphology and chemical composition. However, their formation, composition, configuration and role played in overall health status are still unclear. Clinically, they may be symptomatic; technically, they impede access during endodontic therapy, increasing the risk of treatment errors. Thus, this study aimed to morphologically analyze pulp stones and present their chemical quantification, identifying their main chemical elements. It also correlates the results with their possible induction mechanisms. Materials and Methods: Seven pulp nodules were collected from molar teeth needing endodontic treatment. The morphology of the stones was analyzed by scanning electron microscopy (SEM), and their chemical composition was determined by X-ray dispersive energy spectroscopy (EDX). Results: These structures varied considerably in shape, size and topography. The site of the stones in the pulp cavity was the factor that most affected the morphology. The majority of the stones found in the pulp chambers presented nodular morphology, while those in the root canals presented a diffuse shape, resembling root canal anatomy. The topography of the nodules showed heterogeneous relief, revealing smooth and compact areas contrasting with the rugged and porous ones. The chemical composition varied depending on the location of the nodule in the pulp cavity and the relief of the analyzed area. Radicular stones presented considerably lower calcium and phosphorus content than coronary nodules. Conclusions: The high cellularity rate of the coronal pulp predisposes this region to nodular mineralizations around injured cells. The presence of larger caliber vascular bundles and higher collagen fiber content in radicular pulp determines a diffuse morphological pattern in this region. Understanding the morphology and chemical composition of the pulp stones allows future translational pathways towards the prevention or treatment of such conditions.
