The Efficiency of a Learning Software Compared to e-Books in Dental Education.

Objectives:  Due to time-consuming curricular and extracurricular activities, students in dentistry and medicine can profit from efficient learning strategies. One strategy could be the preparation with individually designed educational software that embed different multimedia sources. The aim of this study was to determine the efficiency of such a program compared with an e-book similar to a traditional textbook.

The role of diabetes mellitus on the formation of severe odontogenic abscesses-a retrospective study.

Objectives: To analyze the correlation of diabetes mellitus and hyperglycemia with severe odontogenic abscesses.

Materials And Methods: Records of all patients in the Department of Oral and Maxillofacial Surgery of the Medical Center of the Johannes Gutenberg-University who underwent inpatient treatment for severe odontogenic abscesses between 2010 and 2016 were evaluated retrospectively regarding diabetes anamnesis, maximum and fasting blood sugar count, and duration until discharge. In order to compare the numbers to a general maxillofacial group, all patients who received inpatient treatment in 2013 for any diagnosis other than an abscess of the head and neck region were analyzed as well, and the numbers were correlated.

Factors accelerating recurrences and secondary tumors in cutaneous squamous cell carcinoma.

To investigate factors that affect and also decrease the duration for recurrences and secondary tumors in cSCC. A retrospective study was conducted for all patients who were treated for a cSCC of the head and neck between 2009 and 2016. Anamnestic as well as epidemiological and histological data were noted and correlated with the occurrence of recurrences and secondary cancers.

Sentinel lymph node biopsy in malignant melanoma of the head and neck.

Background: The aim of this retrospective study was to investigate sentinel lymph node biopsy in patients with head and neck melanoma.

Materials And Methods: Patients who underwent SLNB between 2010 and 2016 were comprised. Epidemiological, radiological, and surgical data were collected and compared to histological findings.

Diabetes and hyperglycemia as risk factors for postoperative outcome in maxillofacial surgery.

Background: Aim of this study was to investigate the frequency of complications in maxillofacial surgery in-patients in correlation to diabetes mellitus or a pathologically altered glucose metabolism.

Materials And Methods: All patients' electronic health records were analyzed retrospectively. Diabetes mellitus anamnesis, the treatment regime, blood glucose levels, and the duration of inpatient treatment were recorded.

Diabetes Mellitus and Its Association to the Occurrence of Medication-Related Osteonecrosis of the Jaw.

To date there is no consensus on the role of diabetes in the development of medication-related osteonecrosis of the jaws (MR-ONJ). Therefore, this study aimed to investigate the prevalence of diabetes and pathological glucose metabolism in patients with MR-ONJ compared to the general population. All maxillofacial surgery inpatients in one year at our department were investigated regarding diagnosis, anamnesis, medication, and blood glucose readings.

Association between eruption state of the third molar and the occurrence of mandibular angle fractures.

Background/aim: Fractures of the mandible, especially the mandibular angle, are one of the most frequent types of injuries of the facial skeleton. In many cases, a retained third molar can be found in the line of the fracture. However, it remains unclear whether a relationship between third molars and mandibular angle fractures exists.

Malignant lymphomas in the head and neck region--a retrospective, single-center study over 41 years.

Objectives: Non-Hodgkin lymphomas are malignant neoplastic proliferations of the immune system that can manifest as nodal or extranodal lymphomas. The aim of this study was to retrospectively investigate the site of occurrence of lymphomas in the head and neck area and to analyze the typical symptoms of patients who presented at an oral and maxillofacial surgical department.

Material And Methods: All patient files from 1971 until 2012 from an Oral and Maxillofacial Surgery of a University were analyzed for the diagnosis non-Hodgkin lymphoma.

Concomitant dental injuries in maxillofacial fractures - a retrospective analysis of 1219 patients.

Background/aim: Traumatic dental injuries are frequently combined with maxillofacial fractures, but literature addressing this topic is rare. In a retrospective study, the frequency of dental lesions in inpatients with traumatic facial injuries was analyzed.

Material And Methods: All patients referred to the Department of Oral and Maxillofacial Surgery of the University Medical Center of the Johannes Gutenberg-University Mainz for inpatient treatment due to facial fractures between January 2001 and December 2007 were analyzed regarding the type of fracture, its localization, and potential concomitant dental injuries.

Intraoperative pelvic nerve stimulation performed under continuous electromyography of the internal anal sphincter.

Purpose: The aim of this animal study was to investigate the effect of intraoperative pelvic nerve stimulation on internal anal sphincter electromyographic signals in order to evaluate its possible use for neuromonitoring during nerve-sparing pelvic surgery.

Methods: Eight pigs underwent low anterior rectal resection. The intersphincteric space was exposed, and the internal (IAS) and external anal sphincter (EAS) were identified.
