Demographic (sex, age), clinical (length of treatment and posttreatment, number of treatment phases, time of Class III elastics), cephalometric (SNA, SNB, ANB, Wits appraisal, SNGoGn, IMPA), and dental cast (peer assessment rating index and arch dimensions) variables were not significantly associated with clinical relapse at T3.
 
  The stability of compensatory treatment of Class III malocclusion in permanent dentition is multifactorial, with few predictive variables. Patients treated with extraction and better orthodontic finishing had a lower risk of relapse, whereas larger maxillary incisor inclination at baseline increased the risk of relapse.

  The use of digital models in orthodontics is becoming increasingly widespread. This study aimed to evaluate the accuracy and performance of digital intraoral scanning under 4 different intraoral environmental conditions.
 
  Four digital models were acquired with TRIOS intraoral scanner (3Shape, Copenhagen, Denmark) for 50 subjects. A total of 200 digital models were divided into 4 groups as follows daylight and saliva (group 1), daylight with saliva isolation (group 2), reflector light and saliva (group 3), and relatively dark oral environment and saliva (group 4). The 4 digital models were superimposed, and the edges of the models were trimmed to create common boundaries (Geomagic Control X; 3D Systems, Rock Hill, SC). Group 2 models were used as a reference and superimposed separately with the models of the other 3 groups. Deviations between corresponding models were compared as means of negative deviation, means of positive deviation, in total area, out total area, positively positioned areas, and negativmance was affected by different environmental conditions, and that caused variations on the surface of digital models. However, the performance of the intraoral scanner was independent of the scanning time and mesiodistal width of the teeth.
  The use of nonvascular bone grafts for immediate mandibular reconstruction has remained a controversial topic. The purpose of the present study was to investigate the variables that might influence graft survival examining the outcomes from 30years of experience.
 
  We designed a retrospective cohort study to analyze the data from patients at a tertiary university medical center who had undergone segmental mandibular resection with immediate reconstruction with a nonvascularized free bone graft with or without adjuncts from 1989 to 2019. The predictor variables recorded included general demographic data, pathologic diagnosis, resection length, reconstruction modality, bone graft type, and inferior alveolar nerve procedures. The primary outcome variable was graft success, defined as bony union demonstrated on panoramic radiographs and mandibular stability demonstrated on clinical examination at 4months postoperatively. Descriptive, bivariate, and linear regression models were computed.
 
  The sample included 4be used to immediately reconstruct mandibular defects greater than 6 cm from benign pathologic lesions; however, larger grafts are more likely to fail.
  Self-inflicted gunshot wounds to the face are one of the most challenging clinical scenarios encountered by oral and maxillofacial surgeons. Knowledge is lacking regarding which factors might influence survival after these devastating injuries, especially pertaining to psychiatric history and substance use. The purpose of the present study was to evaluate the risk factors that might influence the survival of subjects with self-inflicted gunshot wounds to the face.
 
  A retrospective cohort study was designed to analyze the data from subjects presenting to the University of Louisville Trauma Center with self-inflicted gunshot wounds to the face from February 2010 to September 2019. The predictor variables included demographic (eg, age, gender, race), medical and psychiatric history, and toxicology test results.  https://www.selleckchem.com/products/iclepertin.html  The primary outcome variable was death before hospital discharge. Descriptive, bivariate, and logistic regression models were computed.
 
  The sample included 120 subjects, with an age range of 16 to 85s to the face were more likely to survive their injury if they had a reported history of depression or test results positive for a benzodiazepine.
  A hoverboard, or self-balancing scooter, is a battery-powered vehicle with 2 wheels connected by a longboard that requires handsfree operation. The purpose of the present study was to characterize the emergency department visits for hoverboard-related craniomaxillofacial trauma and determine predictors of injuries and hospital admission.
 
  We performed a retrospective cohort study of the National Electronic Injury Surveillance System from 2015 to 2018. The database was searched using the codes for battery-powered vehicles and craniomaxillofacial body parts (ie, head, face, mouth, eyeball, ear). Entries with the term "hoverboard" in their narrative were included. The predictors were gender, age, body part, year, season, setting, and helmet wear. The outcomes were injury diagnoses (ie, dental injury, facial fracture, soft tissue injury, intracranial injury) and hospital admission. Associations between the predictors and outcomes were evaluated using χ
  and t tests.
 
  The final sample included 440 patients, odiagnosis; thus, helmet wear is recommended.
 Craniomaxillofacial injuries from hoverboard accidents have resulted in emergency department visits and hospital admissions since the vehicle's introduction to the consumer market in 2015. Most cases occurred in the winter, which might reflect increased sales and novice riders during the holiday season. Injuries to adults, in the summer or outdoors, appear to be more severe. Intracranial injuries were the most frequent diagnosis; thus, helmet wear is recommended.As treatment evolves and the population who survive childhood cancer ages and increases in number, researchers must use novel approaches to prevent, identify and mitigate adverse effects of treatment. Future priorities include collaborative efforts to pool large cohort data to improve detection of late effects, identify late effects of novel therapies, and determine the contribution of genetic factors along with physiologic and accelerated aging among survivors. This knowledge should translate to individual risk prediction and prevention strategies. Finally, we must utilize health services research and implementation science to improve adoption of survivorship care recommendations outside of specialized pediatric oncology centers.
