Purpose: Knowledge of the nasopalatine canal (NPC) is necessary for understanding the morphology and pathogenesis of lesions that occur in this region. The purpose of the present study was to analyze the dimensions and anatomic characteristics of the NPC in a pediatric population using cone-beam computed tomography (CBCT).
Study Design: Reformatted sagittal, coronal, and axial slices of 368 individual CBCT images were analyzed with regard to dimensions and anatomic features of the NPC.
Results: Funnel shape of the NPC was most commonly found [26.9 % (99)], followed by banana shape [19.6 % (72)]. There was no statistically significant difference (p = 0.317) between girls and boys in terms of NPC shape. The mean width of incisive foramen was found to be 2.53 mm with a significant difference (0.002). The mean NPC length was found to be 10.83 mm and the mean canal length was found to be significantly longer in boys than girls (p < 0.000).
Conclusion: The present study provides new information on the literature concerning the identification of the anatomical structure of NPC. This finding may assist clinicians in understanding the morphology and preventing possible complications in this region.

Background Odontogenic maxillary sinusitis arises mainly from dental origins, emphasizing the connection between dental health and sinus issues. Understanding these relationships is crucial for implant planning, sinus augmentation procedures, and managing post-extraction complications. This knowledge can help clinicians make informed decisions about treatment timing and approach.

Investigating the pattern of extension in the periapical (PA) inflammatory lesions is important in the treatment plan and prognosis of treatment. This study evaluated the topography of PA inflammatory lesions in the first molars using cone-beam computed tomography (CBCT). In this descriptive study, 197 CBCT images about patients in the age group of 14-77 years were analyzed.

Oral and maxillofacial diagnostic imaging is of paramount importance in dental clinical diagnosis, treatment planning, and follow-up procedures. Periapical radiographic examination and numerous panoramic systems are used in routine clinical dental practice. Cone beam CT is widely used and currently the method of choice in oral and maxillofacial implantology, endodontics, maxillofacial surgery, periodontics, degenerative temporomandibular joint disease, orthodontics, airway studies, sleep disorders, and forensic dentistry.

Background: This study aims to investigate the prevalence and morphology of middle mesial canal (MMC) in mandibular first molar (M1M) among a Northwestern Chinese population, and to analyze their relationship with anatomical aspects of the mesial root.
Methods: Cone beam computed tomography (CBCT) was utilized to evaluate 898 M1Ms and assess the incidence and morphology of MMC. The following parameters for M1M with or without MMC were obtained: the vertical distance between the first appearance of MMC and canal orifices (D), the distance between mesiobuccal (MB) and mesiolingual (ML) canals (D1), the buccolingual width(L1) and mesiodistal width (L2) of mesial roots, and the flatness degree(L1/L2) of mesial roots.
