Rapid prototyping modelling in oral and maxillofacial surgery: a two year retrospective study
2015
Background The use of rapid prototyping (RP) models in medicine to construct bony models is increasing. Material and Methods The aim of the study was to evaluate retrospectively the indication for the use of RP models in oral and maxillofacial surgery at Helsinki University Central Hospital during 2009-2010. Also, the used computed tomography (CT) examination – multislice CT (MSCT) or cone beam CT (CBCT) - method was evaluated. Results In total 114 RP models were fabricated for 102 patients. The mean age of the patients at the time of the production of the model was 50.4 years. The indications for the modelling included malignant lesions (29%), secondary reconstruction (25%), prosthodontic …
A randomized clinical trial of topical dexamethasone vs. cyclosporine treatment for oral lichen planus
2021
BACKGROUND Oral lichen planus (OLP) is a common, frequently symptomatic, immune-mediated disease. Various treatments have been used for symptomatic OLP, including corticosteroids and immunosuppressants administered topically or systemically. The aim of this study was to compare the effectiveness of topical dexamethasone vs. topical cyclosporine in treatment of symptomatic OLP. MATERIAL AND METHODS Thirty-two patients with biopsy-proven symptomatic OLP were randomly assigned to two therapeutic groups: dexamethasone 2mg/5ml or cyclosporine 100mg/ml, both administered topically in a swish and spit method three times a day for 4 weeks. The patients were followed up for a total of 6 months. Asse…
What is the accuracy of the surgical guide in the planning of orthognathic surgeries? A systematic review.
2021
BACKGROUND To investigate the true accuracy of the surgical guide in the planning of orthognathic surgeries, which are performed worldwide. MATERIAL AND METHODS A systematic search was conducted in the PubMed database, Web of science, Scopus and Embase, covering August 2020 to January 2021. Studies that included patients with dentofacial deformity including anteroposterior, vertical and asymmetry problems who were undergoing an orthognathic surgery procedure were included; QUADAS-2 was used to determine the risk of bias by analyzing the quality of the studies. A PRISMA (flowchart) was created to show the study selection, keywords, nomination processes, and inclusion and exclusion criteria. …
Effects of mandibular advancement surgery on the temporomandibular joint and muscular and articular adaptive changes--a systematic review.
2016
The objective of this study was to assess the anatomical changes to the condyle and articular disc following mandibular advancement surgery, the adaptation of the masticatory muscles, and the improvement or worsening of temporomandibular disorders (TMD) in patients with pre-existing disorders and those who developed them following surgery. Four databases were searched systematically: PubMed, Scopus, Embase, and Cochrane Library. Of the 544 articles initially selected, 219 were duplicates and a further 165 were excluded on the basis of their titles and abstracts. On reading the full text, 89 were excluded because they were of no interest and 43 because they did not meet the inclusion criteri…
Assessing the need for a protocol in monitoring weight loss and nutritional status in orthognathic surgery based on patients experiences
2017
Background To investigate retrospectively the orthognathic surgery (OGS) patients experience in weight loss and the influence of gender, age, duration of the surgical procedure, length of hospital stay, location of surgery and use of intermaxillary fixation (IMF) or without IMF on postoperative weight loss. Material and Methods A total of 4487 patients treated by OGS where all patients visited the outpatient clinic one, three and six weeks after the surgical procedure. After six weeks, patients filled out a questionnaire in which weight loss was addressed. The patients were asked to give an estimate of their experiences weight loss. The population was first divided in two groups weight loss…
Low-level laser therapy for treatment of neurosensory disorders after orthognathic surgery : a systematic review of randomized clinical trials
2017
Background Low-level laser has been widely used in Dentistry and many studies have focused on its application in oral surgeries. This study was conducted with the aim of searching for scientific evidence concerning the effectiveness of laser to reduce pain or paresthesia related to orthognathic surgery. Material and methods An electronic search was performed in PubMed, Scopus, Science Direct, LILACS, SciELO, CENTRAL, Google Scholar, OpenGrey, and ClinicalTrials.gov, up to November 2016, with no restrictions on language or year of publication. Additionally, a hand search of the reference list of the selected studies was carried out. The PICOS strategy was used to define the eligibility crite…
Evaluation of orthognathic surgery on articular disc position and temporomandibular joint symptoms in skeletal class II patients: A Magnetic Resonanc…
2017
BACKGROUND The purpose of orthognathic surgery is to correct facial deformity and dental malocclusion and to obtain normal orofacial function. However, there are controversies of whether orthognathic surgery might have any negative influence on temporomandibular (TM) joint. The purpose of this study was to evaluate the influence of orthognathic surgery on articular disc position and temporomandibular joint symptoms of skeletal CI II patients by means of magnetic resonance imaging. MATERIAL AND METHODS For this purpose, fifteen patients with skeletal CI II malocclusion, aged 19-32 years (mean 23 years), 10 women and 5 men, from the Isfahan Department of Oral and Maxillofacial Surgery were st…
Self-esteem and depression in patients presenting angle class III malocclusion submitted for orthognathic surgery
2008
Objective: To assess self-esteem and depression in patients submitted for orthognathic surgery. Methods: Assessment was realized on 29 patients, male and female, aged 17 to 46, presenting Angle Class III malocclusion and referred for surgical treatment, during the preoperative (orthodontic preparation) and postoperative (six-month postoperative) periods. Either maxillomandibular or isolated procedures were performed. Two previously validated standardized measurement instruments for this area were used: the UNIFESP-EPM Rosenberg Self-Esteem Scale and the Self-Report Questionnaire-20 (SRQ-20). Descriptive and inferential statistical analysis (Repeated Measures Analysis of Variance and the Bon…
Predictors of health-related quality of life in Serbian patients with head and neck cancer.
2021
The aim of this study was to identify predictors of the Health-Related Quality of Life (HRQoL) in patients with head and neck cancers (HNCs). In total, 345 patients with HNCs were interviewed. A self-report questionnaire was administered to collect data about demographic characteristics, health status, smoking, alcohol consumption habits, and HRQoL. It were used the EORTC Instruments - Quality of Life Questionnaire-Core 30-questions (QLQ-C30), Quality of Life Questionnaire - Head and Neck Module 35-questions (QLQ-H&N 35) and OHIP-14 instrument for HRQoL assessments. Clinical information and treatment data were collected from medical records. Five groups of HRQoL predictors were identified: …

This was an observational cross-sectional study. The questionnaire contained 27 questions based on the SPIKES protocol, which were answered in the SurveyMonkey platform. A total of 186/249 dentists answered the questionnaire. The main specialties reported were 36.02% oral medicine, 21.5% oral pathology, and 9.13% oral and maxillofacial surgery. A total of 44.6% expressed concern about the patient?s emotional reactions, and 46.24% of respondents had never participa…
