“…Most endodontic studies in veterinary medicine focus on the 2D characteristics of a 3D object and thus present limitations. Few veterinary studies have used micro-computed tomography (micro-CT) to assess the morphology of teeth (11)(12)(13)(14)(15)(16)(17)(18). As such, the current understanding of the anatomy of the feline canine tooth pulp cavity stems primarily from the study of intraoral radiographic images.…”

An understanding of the pulp cavity anatomy of individual teeth is essential for success during endodontic therapy. The objective of this study was to document pulp cavity anatomy and summarize numerical data of maxillary and mandibular canine teeth of domestic cats using micro-computed tomography (micro-CT). Thirty-nine canine teeth from eleven domestic cat cadaveric specimens were extracted and prepared for scanning. Segmentation of the pulp cavity was performed using the Avizo (v2022.2) software package. The morphological features of the pulp cavity including overall shape, configuration, presence of apical deltas and lateral canals was recorded. A quantitative analysis was performed on thirty-one teeth to explore associations between pulp cavity volume and length, apical delta length, maximum apical delta foramina number and cusp-to-tip length using a linear mixed model. Correlation between pertinent continuous variables was assessed using a Pearson’s correlation test. Most pulp cavities exhibited varying curvature and ranged from a cylindrical configuration in the coronal third to an ovoid configuration in the middle to apical third. A ribbon-like flattened canal was observed in 6/31 teeth (19%). All canine teeth depicted an apical delta with various configurations except for two teeth that showed a single canal exiting at the apex. In 15/31 teeth (48%), the primary root canal within the apical delta could be clearly identified and in 16/31 (52%) the primary root canal was indiscernible. The results showed that the pulp cavities of maxillary canine teeth were significantly larger and longer and the cusp-to-tip length was longer, when compared to mandibular teeth. The apical delta length was negatively correlated to the volume of the pulp cavity. No specimens depicted lateral canals. This study revealed that the anatomy of the canine tooth pulp cavity in cats can vary considerably and should be a consideration when performing thorough debridement, shaping and obturation of the endodontic system.

This study aims to shed light on animal management influences on the development of pathological changes observed on animal remains from the medieval site of Crkveno Brdo. Animal remains with abnormalities were discovered during archaeological excavations of the medieval settlement at the site of Crkveno Brdo in 2019. The site is situated near Senta in the northern region of modern‐day Serbia. The part of the settlement dated from the 11th to the 15th centuries was excavated. The percentage represented by various mammalian species documents that the most important economic species were cattle and horses, followed by sheep, goats, and pigs. Fishing and hunting were marginal in the settlement subsistence. The analyzed assemblage of bones with lesions consists of 39 specimens with 40 abnormalities. All of the remains exhibiting abnormalities were subjected to macroscopic and stereomicroscope analysis. The specimens with the most prominent changes also underwent x‐ray imaging and histopathological analysis. Almost all lesions were found in domestic animals. The most prevalent lesions in cattle, sheep, goat, and pig were dental and oral pathology, followed by articular abnormalities. In horses, 77% of pathological changes were articular abnormalities, and 11% dental and oral pathology, followed by traumatic lesions and inherited disorders (5.5% each). Congenital morphological variation is represented by a single specimen of horse lumbar vertebra. Pathological alterations were also noted in dogs, as was a severe healed tibiofibular fracture in a frog. Pathological alterations were related to external factors and specifically to patterns of animal management. Dental pathologies in cattle, sheep/goats, and pigs were primary attributed to malnutrition quality; articular abnormalities in horses, similar to aging and environmental factors, most likely work related.
