Burnout, depression and suicidal ideation in dental students
2013
Objectives: To investigate the prevalence, gender influence, and relationships between burnout, depression and suicidal ideation within the last year among second, fourth and fifth-year dental students. Study Design: A cross-sectional study was carried out in 212 dental students enrolled in the second, fourth and fifth years at the School of Dentistry of Seville using the Maslach Burnout Inventory-Student Survey and the MBI-Human Services Survey, the "Patient Health Questionnaire-2", and the "Questions about Suicidal Ideation and Attempted Suicide". Results: The response rate among dental students was 80%. Burnout prevalence in dental students was higher in second and fourth years than in f…
A retrospective clinicopathological study on oral lichen planus and malignant transformation: Analysis of 518 cases
2011
Objective: To investigate the epidemiological and clinical characteristics of a relatively large cohort of patients with oral lichen planus (OLP) from eastern China. Study design: A total of 518 patients with histologically confirmed OLP in a long-term follow-up period (6 months-21.5 years) were retrospectively reviewed in our clinic. Results: Of the 518 patients, 353 females and 165 males were identified. The average age at diagnosis was 46.3 years (range 9-81 years) with the buccal mucosa being the most common site (87.8%). At initial presentation, white lichen and red lichen was seen in 52.3% and 47.7% patients, respectively. Of these, 5 (0.96%) patients previously diagnosed clinically a…
The clinical characteristics of benign oral mucosal tumors
2013
Objectives: To investigate the clinical characteristics and pre-biopsy provisional diagnoses of benign oral mucosal tumors. Material and Methods: A 10- year retrospective analysis of all benign tumors of the oral mucosa, from a univer- Methods: A 10- year retrospective analysis of all benign tumors of the oral mucosa, from a univer - sity- affiliated oral and maxillofacial surgery department. Results: 146 benign tumors were included. The mean age was 49.6 years, with an approximately equal gender dis - tribution. The most prevalent tumor types were lipomatous tumors (27.4%), vascular (23.3%), and salivary gland tumors (16.5%). Tongue, labial and buccal mucosa were the most frequently involv…
The relevance of uniform reporting in oral leukoplakia: Definition, certainty factor and staging based on experience with 275 patients
2012
The aim of the present study was to evaluate the definition of oral leukoplakia, proposed by the WHO in 2005 and taking into account a previously reported classification and staging system, including the use of a Certainty factor of four levels with which the diagnosis of leukoplakia can be established. In the period 1997-2012 a hospital-based population of 275 consecutive patients with a provisional diagnosis of oral leukoplakia has been examined. In only 176 patients of these 275 patients a firm diagnosis of leukoplakia has been established based on strict clinicopathological criteria. The 176 patients have subsequently been staged using a classification and staging system based on size a…
Spontaneous fractures of the mandible concept & treatment strategy
2015
Background Spontaneous fractures of the mandible dispose a surgical challenge in comparisons to fractures caused by trauma due to several complicating factors. Additionally: controversies exist concerning the terminology of the field. Material and Methods We conducted a retrospective study of all patients with mandibular fractures, with exclusion of fractures of the coronoid process and the alveolar process, treated at the Department of Oral and Maxillofacial Surgery, Aalborg University Hospital, Denmark between February 2003 and February 2013. Data collected from the medical records included sex, age, cause of fracture, site of fracture, and treatment. Results We identified 517 patients wi…
Single horizontal Y-V vermilion plasty including orbicularis oris muscle repair for secondary correction of the whistling defect: a universal techniq…
2012
Objectives: The present prospective study aimed at objectively evaluating the relevance of a single horizontal Y-V vermilion plasty including orbicularis oris muscle repair for secondary correction of whistling deformities in unilateral as well as bilateral cleft lip cases. Study Design: Ten patients were included in the study (mean age 20.2±6.2 years). The size of the whistling defects was determined on photographs before and 12 months after surgery. Additional surgical procedures like columella lengthening and rhinoplasty were documented. Results: Seven minor and 3 moderate whistling defects were corrected. In 7 patients additional procedures were carried out. The data of the 12 months fo…
Influence of hemostatic agents upon the outcome of periapical surgery: dressings with anesthetic and vasoconstrictor or aluminum chloride
2011
Objective: To evaluate the effects of different hemostatic agents upon the outcome of periapical surgery. Design: A retrospective study was made of patients subjected to periapical surgery between 2006-2009 with the ultrasound technique and using MTA as retrograde filler material. We included patients with a minimum follow-up of 12 months, divided into two groups according to the hemostatic agent used: A) dressings impregnated in anesthetic solution with adrenalin; or B) aluminum chloride paste (Expasyl™). Radiological controls were made after 6 and 12 months, and on the last visit. The global evolution scale proposed by von Arx and Kurt (1999) was used to establish the outcome of periapica…
Management of dental extraction in patients with Haemophilia A and B: a report of 58 extractions
2013
Objectives: Patients with inherited bleeding disorders are at high risk of bleeding following oral surgery and present challenges to the oral surgeons. Aim of this study was to report our experience in dental extraction in patients exhibiting Haemophilia A and B between 2007 and 2012. Patient and Methods: 58 dental extractions in 15 patients during 19 interventions were performed. Replacement therapy with recombinant and plasma-derived factor VIII and IX was applied systematically in combination with antifibrinolytic treatment and local haemostatic measures. The following data were recorded: type of surgery, applied local haemostatic measures, general substitution, systemic antifibrinolytic…
The role of a labial salivary gland biopsy in the diagnostic procedure for Sjögren’s syndrome; a study of 94 cases
2014
Objectives: The purpose of the present study is to examine the role of the outcome of the labial salivary gland biopsy (LSGB) in the diagnostic procedure of patients suspected of suffering from Sjögren's syndrome (SS). Material and Methods: In a retrospective study the result of histopathological assessment of 94 consecutively taken labial salivary gland biopsies has been examined. For the diagnosis of SS the American-European Consensus Group classification (AECG, 2002) have been used. The outcome of the assessment has been discussed in relation to a recently reported classification provided by the American College of Rheumatology (ACR, 2012). Results: In the 94 LSGBs support for a diagnosi…
Morphologic outcome of bimaxillary surgery–An anthropometric appraisal
2014
Objectives: To adequately perform orthognathic surgery procedures, it is from basic interest to understand the morphologic changes caused by orthognathic surgery. Anthropometric analyses of standardized frontal view and profile photographs could help to investigate and understand such changes. Study Design: We present a pre- to postoperative evaluation of orthognathic surgery results based on anthropometric indices described by Farkas and cephalometric measurements. 30 Class III patients undergoing maxillary advancement by Le Fort I Osteotomy and mandibular setback by bilateral sagittal split osteotomy were evaluated. Preoperative as well as three and nine months postoperative lateral cepha…
