The epidemiology and management of odontomas: a European multicenter study.

Introduction: Odontoma is the most commonly diagnosed odontogenic tumor of the oral cavity. The objective of the present study was to assess the demographic variables, patterns, diagnostic features, and management issues of odontomas treated at several European departments of maxillofacial and oral surgery.

Materials And Methods: This study was conducted at 8 European departments of oral surgery between January 1, 2004, and December 31, 2018.

Methylation of tumour suppressor genes in benign and malignant salivary gland tumours: a systematic review and meta-analysis.

The aim of the present systematic review was to critically analyse the relationship between tumour suppressor genes (TSGs) promoter methylation, a potent mechanism of gene silencing, and the development of salivary gland tumours, as well as the possible effect on clinical/histological characteristics. Review protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) database (registration ID CRD42020218511). A comprehensive search of Web of Science, Scopus, PubMed, and Cochrane Central Register of Controlled Trials was performed utilizing relevant key terms, supplemented by a search of grey literature.

Quality of life following maxillofacial trauma in the elderly: a multicenter, prospective study.

Background/aims: When facial trauma involves elderly patients, the possible presence of frailty and comorbidities in victims of trauma may worsen the posttraumatic symptoms and decrease quality of life. The aim of this multicenter study was to assess the quality of life following surgical or non-operative management of maxillofacial trauma in elderly patients.

Materials And Methods: This cohort study was based on the administration of validated self-administered questionnaires to all the geriatric patients (70 years or more) with facial fractures from the involved maxillofacial surgical units across Europe, since 1st January 2019 to 31st June 2019.

Medication-Related Osteonecrosis of the Jaws: Two Center Retrospective Cohort Studies.

This retrospective cohort study aims to describe characteristics of patients with MRONJ, to identify factors associated with MRONJ development, and to examine variables associated with favourable outcome. Totally 32 patients were followed and observed: 21 females and 11 males, in the age range 35-84 in the period from 2009 to 2018. Clinical, radiological examination (Orthopantomograph and CBCT) and biopsy were performed in order to achieve diagnosis.

Real-time thermographic analysis of low-density bone during implant placement: a randomized parallel-group clinical study comparing lateral condensation with bone drilling surgical technique.

Objectives: To compare the effect of two surgical techniques, lateral condensation and bone drilling, on changes in temperature of the adjacent low-density bone during implant placement into posterior maxilla and to investigate the influence of the host factors - age, gender, region of implantation, bone density, and thickness of the cortical bone at the recipient sites.

Material And Methods: Local bone temperature was measured thermographically during implant placement into posterior maxilla following lateral bone condensing (test group) or bone drilling (controls). The main study outcomes were baseline bone temperature prior to implantation and maximum bone temperature recorded during implantation.

Surgical management of squamous cell carcinoma of the lip: analysis of a 10-year experience in 223 patients.

Background: The most common type of lip carcinoma is squamous cell carcinoma (SCC), accounting for approximately 90% of all oral malignancies. Currently, surgery and/or radiotherapy are considered the standards of care for SCC of the lip.

Materials And Methods: We retrospectively analyzed medical records of patients diagnosed with SCC of the lip at the Clinic for Maxillofacial surgery at University of Belgrade (Belgrade, Serbia) during a period between 1991 and 2000.

[Use of the modified Fries technique in the reconstruction of the lower lip after the removal of a malignant tumor].

Background/aim: Lip carcinoma makes about 1/4 of all oral carcinomas. Primary treatment of the lower lip carcinoma means radical excision of the full thickness of the lower lip tissue together with the tumor. The reconstruction of the defect accomplished after the removal of the lower lip tumor is a challenge for the surgeon and requires a detailed preoperative planning, the right choice of the method for reconstruction and the knowledge of the adequate surgical techniques needed.

[Positional changes of the lower and upper anterior teeth after surgical correction of mandibular prognathism].

Background/aim: To establish the influence of surgical corrections of mandibular prognathism upon the position of the lower and upper anterior teeth (incisors).

Methods: The changes in position of the lower and upper anterior teeth (incisors) after the surgical correction of mandibular prognathism were analyzed by means of x-ray craniometry in 183 patients (female: n = 110, male: n = 73) in which the correction had been made in accordance with the principles of sagital osteotomy of the mandibular ramus. There were 4 angular and 2 linear parameters determined in the pre- and postoperative tele-x-ray-pictures.
