Mandible reduction procedures are currently very popular in Asian countries. But many misconceptions or differences in concepts about these procedures still exist, mainly because of preconceived ideas and restriction in communication. The author reviewed articles and found some misconceptions about these procedures. Also, the author added some opinions regarding new ideas about these procedures (i.e., minimal incision technique and botulinum toxin), as well as logical backgrounds of associated concepts. The intraoral approach is the safest and most effective procedure. The sagittal split ostectomy is the most important procedure for mandible reduction.

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.

Background: Examining stress distributions in abutment teeth with periapical lesions is essential for understanding their biomechanical impact on dental structures and tissues. This study uses finite element analysis (FEA) to evaluate these stress patterns under occlusal forces, aiming to enhance treatment strategies and prosthetic designs.
Methods: Three FEA models were created: a healthy mandibular premolar (Model 1), a premolar with a single crown and a lesion repaired using a fiber-post (Model 2), and 3) a premolar with a lesion repaired using fiber-post to support a four-member bridge (Model 3).

Determining the ecology of fossil species presents considerable challenges due to the often fragmentary preservation of specimens. The mammaliaform Hadrocodium wui from the Jurassic of China is known only from the cranium and mandible but may have had a fossorial lifestyle. It shares morphological similarities with talpid moles and soricid shrews and is closely related to other fossorial mammaliaforms.

Background: The choice of treatment for subcondylar fractures in children and adolescents remains a controversial issue. The aim of this study was to evaluate the association between the treatment modality of subcondylar fractures and functional outcomes at the six-month follow-up.
Methods: This retrospective study examined a cohort of children and adolescents with unilateral or bilateral subcondylar fractures treated at a level 1 trauma center over a five-year period.
