Discipline-specific terminology is a central element of the vocabulary used by dentists and scientists in the context of their professional activities and plays a critical role in the understanding of dentistry. A number of controversial terms and non-standardized definitions exist in the field of endodontology. For example, in root and canal anatomy, variations exist in the definitions of root morphology (including apical bifurcation, fusion and dilaceration), pulp chamber anatomy (including the outline of the floor, pulp horns and location of the root canal orifice), apical root canal bifurcations, canal isthmuses, accessory canals and apical foramen. This narrative review provides a critical analysis of a range of controversial terms currently used to describe root and canal anatomy. It also addresses the consequences of using such controversial terms on the accuracy and reliability of research findings and clinical practice.

Aim: Prickle planar cell polarity (PCP) protein 2 (Prickle2) encodes a homologue of Drosophila prickle and is involved in the non-canonical Wnt/PCP signalling pathway. However, its exact role in dentinogenesis remains unclear. Dentinogenesis, a key process in tooth morphogenesis, involves the patterned arrangement of odontoblasts and the formation of dentine matrix along the pulp cavity.

Aim: This article aims to introduce and elaborate on the innovative concept of Functional Endodontic Volume (FEV), a biologically driven approach to root canal shaping. This concept emphasizes the importance of volumetric preparation aimed at enhancing irrigation dynamics during root canal treatment, all while maintaining the tooth's structural integrity.
Summary: In recent years, contemporary endodontics has progressively shifted towards methods that prioritize irrigation-based disinfection.

Objective: The aim of this study is to compare the radiological measurements of patients who underwent rhinoplasty using a piezo device with those of patients who underwent rhinoplasty using a classical osteotome.
Methods: A total of 60 patients were included in the study: 30 rhinoplasty patients who underwent piezosurgical osteotomy and 30 who underwent classical osteotomy. Preoperative and postoperative functional and aesthetic outcomes were compared using NOSE and ROE scores.

Severe periapical cysts frequently result in tooth loss with concomitant severe alveolar bone destruction, precluding immediate implant placement. Autogenous tooth transplantation (ATT), which involves transplanting the patient's own tooth to the recipient site, offers a biological approach to reconstruct both the dentition and supporting bone structures. This report presents a 25-year-old female with a mobile, discolored maxillary right lateral incisor (#12) exhibiting grade 3 mobility due to a large periapical cyst (extending to #14 on CBCT) with root developmental arrest, secondary to Oehlers type II dens invaginatus.

Introduction: Although several elegant studies have reported apical periodontitis prevalence in different populations, far less is known about its associated bone loss and its correlation to sex and age. Thus, this study investigated the impact of sex and age differences on the severity of apical periodontitis (AP) using cone-beam computed tomography (CBCT) and a volumetric periapical index (CBCT-PAI).
Material And Methods: CBCT scans of 401 patients (1,027 teeth) were analyzed by calibrated examiners in CBCTPAI.
