Classification of impacted maxillary canines facilitates interdisciplinary communication. Cone beam computed tomography (CBCT) has proven to be superior for the localization of impacted maxillary canines compared with 2D imaging. The purpose of this study was to retrospectively classify a cohort of impacted maxillary canines, using a new developed 3D classification for impacted maxillary canines that is easy to use and does not require complex analysis of the 3D images. A retrospective cohort study was designed, containing CBCT data of 130 patients (male/female: 48/82; median age 16) with a total of 162 impacted maxillary canines. The proposed classification was based on four criteria: vertical crown position, mesiodistal tooth postion, bucco-lingual crown position, and associated pathology. For all included patients, classification criteria were identified and correlated to treatment selection using a newly developed 3D classification. The most common positions were vertical crown position at apical one third of neighboring teeth, mesiodistal tooth angulation, and palatal crown position. The most frequent associated pathologies were dilaceration of the root and resorption of a neighboring tooth. Significant associations among classification variables and treatment options were observed. Limitations of this study are the retrospective design. CBCT enabled 3D assessment of impacted maxillary canines allowing a classification system that may have an impact on further treatment strategies.

Aim: The aim of the present study was to comparatively evaluate the retention of complete dentures and oral health-related quality of life (OHRQoL) of patients with conventional and bioelectric impressions or transcutaneous electric nerve stimulation (TENS).
Materials And Methods: A total of thirty (n = 30) completely edentulous patients were randomly distributed into two groups: Group-C (n = 15) (Conventional) and Group-T (n = 15) (bioelectric). In Group C, border molding was performed using the manual manipulation of borders, and the final impression was made using zinc-oxide eugenol.
Impact of Vision Defects on Tooth Shade Selection: A Comparative of Spectrophotometry and Shade Guides in a Cross-Sectional Clinical Study.

Tooth shade selection is a fundamental factor in the success of dental restorations, and visual impairment may adversely affect this process. The aim of this cross-sectional clinical study was to determine whether visual impairment influences shade selection using two methods: spectrophotometry and shade guides. : The sample consisted of 2796 maxillary and mandibular teeth, and shade selection was measured subjectively with a shade guide (VITA Classic, VITA Zahnfabrik) and objectively with a spectrophotometer (VITA Easyshade V, VITA Zahnfabrik, Bad Säckingen, Germany).

: Sinus lifting, a procedure to augment bone in the maxilla, may cause complications such as sinusitis due to impaired drainage. This study aimed to assess how sinus lifting impacts airflow in the sinus cavity, which is essential for patients undergoing dental implants. Using computational fluid dynamics (CFD), this research analyzed airflow changes after sinus floor elevation, offering insights into the aerodynamic consequences of the procedure.

Background: Virtual surgical planning for orthognathic surgery typically relies on two methods for intraoperative plan transfer: CAD/CAM occlusal splints and patient-specific implants (PSI). While CAD/CAM splints may offer limited accuracy, particularly in the vertical dimension, PSIs are constrained by higher costs and extended preparation times. Surgical navigation has emerged as a potential alternative, but existing protocols often involve invasive registration or lack transparent evaluation.

Background Indirect pulp capping (IDPC) is a preferred treatment for pulp preservation in primary teeth. However, the survival rate of IDPC in primary teeth and impact factors is still equivocal.Aims To evaluate the survival rate of IDPC in primary teeth with a deep carious lesion approximating the pulp but without irreversible pulpitis or periapical disease.
