Objective: We present our experience of success with immediate third molar transplants in young individuals while secondarily assessing factors predicting failure.
Study Design: A total of 57 cases of third molar transplant with both open and closed apices were studied in individuals aged 15 to 25 years. Factors influencing prognosis were analyzed by univariate and multivariate analysis.
Results: The replaced teeth included 17 maxillary molars (29.8%) and 40 mandibular molars (70.2%). After a follow-up of 19.9 ± 2.8 months, 49 cases (86%) were successful; 7 (12.3%) cases failed owing to root resorption, and 1 (1.7%) failed owing to infection. Pulp revascularization was seen in all successful cases with open apices. Proximal grinding of donor tooth was significantly associated with failure (odds ratio, 12.5; P = .025).
Conclusions: Autogenous third molar transplant is an excellent and viable treatment modality. By using proper case selection and minimizing damage to the donor tooth root, high success rates can be achieved.

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.

The pesticide Dichlorodiphenyltrichloroethane (DDT) and its degradation by-products (Dichlorodiphenyldichloroethane-DDD and dichlorodiphenyldichloroethylene-DDE) are health concerns. This study aimed to investigate the impact of multigenerational exposure to traces of DDD and DDE on odontogenesis Wistar rats were allocated in 4 groups over 2 generations (F1 and F2). Water was provided ad libitum throughout the animal's life groups: control - natural water; DDD - 0.
