Background: Post and core restorations are performed (generally after treating the root canals of the tooth) when the majority of the tooth structure has been rendered ineffective to support itself/the crown of the tooth. In this clinical study, we aim to compare the difference between post and core treatment of anterior and posterior teeth and their success/failure rates.
Objective: Our investigation aimed to compare the clinical survival rates of custom-fabricated cast metal post-and-cores in cases of anterior and posterior teeth while controlling for the population's age and gender, type of post material, length of the post, amount of alveolar bone tissue supporting the roots, tooth location in the dental arch, and type of cement used, as well as the effect of opposing dentition and the type of definitive prosthetic treatment received.
Methods: 112 individuals who had received root canal therapy (RCT) and were chosen to receive post and core therapy following their RCT were chosen for the study, and a total of 164 teeth were scheduled to undergo the therapy. All the posts used were made of cast metal, and the patients were divided into two groups: 48 individuals had the posts placed in their posterior teeth (a total of 71 teeth in this case), and the second group was made up of the remaining 64 patients, all with 93 teeth in the anterior region. The follow-up was done twice at a six-month interval after cementation was complete.
Results: No significant changes were observed between the stability of the post structures in the anterior and posterior teeth that were examined, and the survival rates were found to be similar in both instances.
Conclusion: The cast metal posts performed at a similar success rate for the one-year period when the teeth were under our observation, and there were no considerable changes seen statistically. But it must be mentioned that a short follow-up period was observed, so the results might probably see some variations when a longer period of time is taken into consideration.

Orthodontic decompensation prior to orthognathic surgery often requires complex mandibular tooth movements. These movements depend on stable posterior anchorage, which is not always reliably achieved with miniscrews or miniplates. This case report describes the case of an 18-year-old patient undergoing presurgical orthodontic treatment, in whom bilateral Abalakov anchorage was performed.

Objective: To evaluate the impact of occlusion type and artificial intelligence-based computer-aided design (CAD) software on the geometric accuracy and clinical quality of auto-generated anterior and posterior crown designs.
Methods: Five typodont models representing various occlusion types (normal, Class I anterior diastema, Class II division 1, Class II division 2, and Class III anterior crossbite occlusion) underwent crown preparation for the maxillary right central incisor and first molar. Ten sets of intraoral scans were obtained from each prepared model, and crown designs were automatically generated using two software programs: deep learning-based (DL; Dentbird) and conventional automated (CA; Auto Workflow, 3Shape) (n = 10).

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.

Objective: To develop a technique for 3D analysis of the upper part of the cervical spine, to study possible correlations with temporomandibular joint (TMJ) parameters in patients with signs of its dysfunction.
Material And Methods: The data from cone beam computed tomography (CBCT) of the heads of 92 patients who sought treatment for TMJ dysfunction (49 people), comprehensive dental treatment (28 people), and orthognathic surgical treatment (15 people) were analyzed. Patients with signs of TMJ dysfunction were divided into 2 subgroups: 1 - patients with asymmetric narrowing of the articular gap (24 people); 2 - patients with symmetrical narrowing (25 people).
