Objective: The purpose of this study is to analyze the incidence and the type of the bifid mandibular canal (BMC) by using cone beam computed tomography (CBCT) images.
Methods: A total of 216 patients (104 female and 112 male) who underwent CBCT were included in this study. The CBCT images were evaluated for the incidence and the type of the BMC.
Results: BMC was observed in 39 (18.06%) of 216 patients and 50 (11.57%) of 432 sides, female 18 (17.31 %) and male 21 (18.75%). BMC were classified into four types: type I 17 sides (3.94%), type II 11 sides (2.55%), type III 20 sides (4.63%), and type IV 2 sides (0.46%).
Conclusion: BMC is detected at a high rate by using CBCT. When doctors perform surgical procedures in the mandible, they should pay attention to the anatomical variations of BMC of the mandibular canals.

Introduction: The prevention of diabetic foot ulcer (DFU) involves the classification of risk, systemic care, regular examinations, foot care, therapeutic education and adjunct treatments. Photobiomodulation (PBM) has been successfully administered for the healing of DFU and its preventive effects have drawn the interest of researchers.
Methods And Analysis: The purpose of the study is to assess the effect of PBM for the prevention of DFU through a randomised, controlled, double-blind, clinical trial.

Objective: To investigate the physiological characteristics of subspecies (Bti) with double mutations of and genes and to assess the activity of Bti against larvae of under different external factors, so as to provide the theoretical evidence for the use of engineered bacteria of Bti for effective mosquito control.
Methods: wild-type strain Bt-59 and Bt-59 strain with mutation [Bt-59 (Δ)] were cultured in nutrient broth media for 24 hours, and Bt-59 strains with mutation [Bt-59 (Δ)] and double mutations of and [Bt-59 (Δ)] were cultured in nutrient broth media for 48 hours. Then, 5 μL of culture media were transferred to glass sides, and cell morphology and mother cell lysis were observed under an optical microscope.

Pterygomaxillary separation (PMS) is an important step in Le Fort I osteotomy procedure, without which complete mobilization of the maxilla cannot be achieved. The aim of this study was to evaluate PMS patterns and their relationship with the anatomic measurements in Le Fort I osteotomy. In this prospective observational study cone beam computed tomography (CBCT) was used to measure the anatomic variables of the pterygomaxillary junction (PMJ) region including thickness, width, the distance between the most concave point at the lateral surface of PMJ and the greater palatine foramen (C-GPF), and the angle preoperatively, and the separation patterns postoperatively divided into the clean-cut type, maxillary sinus type, and the pterygoid fracture type.
