Aesthetic appraisal is rarely included in the objective assessment of outcome studies of impacted maxillary canines treatment. The present study aimed to validate a new index for assessing the aesthetic appearance of maxillary canines and adjacent soft tissues. The Department of Oral and Maxillofacial Surgery at University Hospitals Leuven. Four oral-maxillofacial surgeons, two orthodontists, two prosthodontists, and two lay persons rated 11 maxillary canines and adjacent soft tissues according to the new index. Each of the examiners repeated the examination three times with a 2-week interval. Twelve relevant aesthetic variables were selected on the basis of the anatomic form, color, and surface characteristics of the canine crown and on the basis of the anatomic form, color, and surface characteristics of the adjacent soft tissues. Intraclass correlation (ICC) coefficient and Fleiss' kappa statistics were performed to analyze the intrarater and interrater agreement. The index proofed to be a reliable assessment tool. Considering the cumulative assessment of the Maxillary Canine Aesthetic Index (MCAI), the mean ICC value for the interrater agreement of the 10 examiners was 0.71, representing a good agreement. Intrarater agreement ranged from 0.10 to 0.91. Interrater agreement (Fleiss' kappa statistics) calculated for each variable ranged from 0.08 to 0.98. The MCAI is a tool in rating aesthetic outcome of impacted canine treatment and adjacent soft tissues. The MCAI can be used to evaluate the aesthetic outcome after surgical exposure or transalveolar transplantation of maxillary canines.

Biomechanical behavior of titanium, cobalt-chromium, zirconia, and PEEK frameworks in implant-supported prostheses: a dynamic finite element analysis.

Background: The mechanical properties of framework materials significantly influence stress distribution and the long-term success of implant-supported prostheses. Although titanium, cobalt-chromium, zirconia, and polyether ether ketone (PEEK) are widely used, their biomechanical performance under dynamic loading conditions remains insufficiently investigated. This study aimed to evaluate the biomechanical behavior of four framework materials with different Young's modulus using dynamic finite element stress analysis.

Introduction: The complexity of treating impacted maxillary canines varies based on their angulation and position within the dental arch. The aim of this research was to compare the mesiodistal angulation of maxillary canines according to their impaction sector.
Methods: This cross-sectional study evaluated 229 impacted maxillary canines in 171 panoramic radiographs from two private radiology centres in Uruguay and Chile of individuals of both sexes aged 11 years and older with impacted maxillary canines.
Reconstruction of a rostral maxillary defect by two custom-made titanium implants following a partial maxillectomy for treatment of squamous cell carcinoma in a dog.

This case report describes the reconstruction of a rostral maxillary defect by two custom-made titanium implants following a rostral partial maxillectomy for treatment of squamous cell carcinoma (SCC) in a seven-year-old dog. An incisional biopsy and CT scan were performed to establish the diagnosis, to plan possible surgery, and to assess the margins of the tumour. The patient had no radiographic signs of metastasis at the time of diagnosis.

Objectives: This study aimed to determine the sequence and eruption chronology of permanent teeth in school children and adolescents of Chennai and compare the findings with an existing standard table. Additionally, the study also attempted to explore the influence of sex, body mass index (BMI), and socioeconomic status (SES) on tooth eruption patterns.
Methods: A cross-sectional study was designed, and 12,650 children aged 5-18 years were selected from thirty-five schools using a multistage random sampling method.
Minimally invasive endodontic treatment through the labial/buccal cervical approach - protocol and case series.

Department of Endodontics, Qingdao Stomatological Hospital Affiliated to Qingdao University, Qingdao, Shandong province, China. Electronic address:
Introduction: Traditional access cavity preparation involves removing the roof of the pulp chamber and smoothing the dentin bulges at the root canal orifice, thereby creating straight-line access. However, this may damage more healthy dental tissue and reduce the tooth's fracture resistance. This case series presents a novel minimally invasive endodontic protocol for one maxillary canine and four mandibular premolars, which required root canal therapy due to labial/buccal cervical decay that caused pulpitis or periapical periodontitis.
