Accuracy in defining a disease makes it easier to study and understand. Similarly, with injuries to the teeth, a comprehensive classification is an aid to correct diagnosis and treatment planning. A thorough review of various classifications of tooth fractures shows that, despite an emphasis on traumatic dental injuries, a consensus needs to be arrived at, especially among clinicians and general/family dentists. The ideal classification would be applicable to both primary and permanent dentition, based on tooth fractures in both the horizontal and vertical planes, encompassing all possible sites, easy to comprehend, communicable amongst health professionals and clinically relevant. With recent improvements in conservative techniques, it is now clinically possible to preserve natural teeth even if they have been horizontally or vertically fractured, and thus an in-depth understanding and knowledge of tooth fractures, together with a simplified classification, is now more than ever essential.

Pulp health and calcific healing of a complicated crown-root fracture with additional root fracture in a maxillary incisor: A case report.

Background: Complicated crown-root fracture (CRF) involves severe injury to the crown, root, and pulp, and may be accompanied by multiple root fractures. The loss of a tooth has lifelong consequences for children and teenagers, but the maintenance of pulp health and the calcific healing of multiple root fractures are rarely reported in the literature.
Case Summary: This case reports healing of a permanent tooth with complicated crown-root and additional root fractures, in which pulp health was maintained.

Background: Several studies reported an association between the number of teeth and the incidence of hip fractures in observational studies, mainly in middle-aged adults. This retrospective cohort study aimed to clarify the association between the number of teeth and the incidence of hip fractures.
Methods: In this retrospective cohort study, a total of 256,772 participants aged 75 years or older who underwent public dental checkups in Japan were evaluated.

The human tooth's morphology, which includes variations in cusp numbers and patterns, is of tremendous interest to anthropologists, morphologists, and dentists. Cusp 6 is an additional cusp that is very seldom encountered in primary or permanent mandibular molars, especially first molars. A supernumerary cusp located lingual to the distobuccal cusp at the crown's distal border is cusp 6.

Introduction And Importance: Intraosseous anesthesia (IOA), an important technique in dental anesthesia, delivers anesthetic directly into the bone, enhancing patient comfort and minimizing side effects. Despite advantages, several disadvantages are known such as injection discomfort, root damage, mechanical obstructions and needle fractures. This report highlights a rare yet significant complication of focal mandibular osteonecrosis following IOA.
