Objectives: The aim of this study is to evaluate the position of impacted third molars based on the classifications of Pell & Gregory and Winter in a sample of Bhopal patients.
Study Design: In this retrospective study, up to 1100 orthopantomograms (OPG) of the patients who were reported to the MaxilloFacial Department of PDA and Chowdhary hospital from January 2011 to December 2012 were evaluated.
Results: Among 1100 patients, 730 were male and 370 were female patients. Of the 1100 OPGs studied, 3,910 third molars were noticed either impacted or erupted and 490 third molars were missing. The most common angulation of impaction in the mandible was in vertical position (41.4%) followed by mesioangular impaction (33.3%) and the most common angulation of impaction in the maxilla was the vertical (67.4%) which was followed by 15.2% in distoangular impaction. The level of eruption of impacted third molar was found to be 43.9% at level A, 34.8% at level B and 21.3% at level C. There was no significant difference between the right and left sides in both the jaws.
Conclusion: The pattern of third molar impaction in the region of Bhopal is characterized by a high prevalence of impaction, especially in the mandible. The most common angulation was the vertical in the mandible as well as in the maxilla. The most common level of impaction in mandible was level A and in maxilla is level C and there was no any significant difference between the right and left sides in both jaws.

Objective: The aim of this study was to assess symmetry of developmental stage of permanent teeth between the left and right side of the jaw, as well as between the maxilla and the mandible.
Methods: A sample of 150 panoramic radiographs of individuals aged 6-20 years (69 males, 81 females) were selected from an open-access radiographic collection (Maxwell Museum of Anthropology's orthodontic collection, Albuquerque, USA). All developing immature permanent teeth (n = 489) were scored by the first author using Moorrees and Demirjian tooth stages.

Background: To compare the effects of first premolar extraction, molar distalization, and non-extraction treatments on the angulation and vertical positions of maxillary second molars (MxM2s) and maxillary third molars (MxM3s). To our knowledge, this is the first study to compare the effects of three different treatment types on MxM3 simultaneously.
Methods: Initial (T0) and final (T1) panoramic radiographs of three different patient groups were analyzed: first premolar extraction group (n = 26 patients, 52 MxM2, 52 MxM3), molar distalization group (n = 20 patients, 40 MxM2, 40 MxM3), and non-extraction group (n = 31 patients, 62 MxM2, 62 MxM3).

The reduction in alveolar ridge height and width after tooth extraction poses a substantial challenge for dental implant restoration. This study aimed to observe the roles of S100A8 in the inflammatory response and bone resorption following tooth extraction. Rat mandibular second molars were extracted.

Background: Assessing the difficulty of impacted lower third molar (ILTM) surgical extraction is crucial for predicting postoperative complications and estimating procedure duration. The aim of this study was to evaluate the effectiveness of a convolutional neural network (CNN) in determining the angulation, position, classification and difficulty index (DI) of ILTM. Additionally, we compared these parameters and the time required for interpretation among deep learning (DL) models, sixth-year dental students (DSs), and general dental practitioners (GPs) with and without CNN assistance.
