Temporomandibular disorders : a case-control study
2012
Objective: To compare the risk factors and clinical manifestations of patients with temporomandibular disorders (TMDs) diagnosed according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) (axis I) versus an age and gender matched control group. Study Design: A total of 162 patients explored according to the RDC/TMD (mean age 40.6±18.8 years, range 7-90; 11.1% males and 88.9% females) were compared with 119 controls, measuring differences in TMD risk factors (sleep disturbances, stress, psychoactive medication, parafunctions, loss of posterior support, ligament hyperlaxity) and clinical variables (joint sounds, painful muscle and joint palpation, maximum aperture…
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…
Confirming the mechanisms behind cognitive-behavioural therapy effectiveness in chronic pain using structural equation modeling in a sample of patien…
2016
Objective To evaluate whether therapeutic mechanisms assumed to explain the effect of cognitive behavioural therapy (CBT) concerning temporomandibular symptoms are confirmed by structural equation modelling. Method Patients were randomly assigned to either an experimental group receiving CBT (N = 41) or a standard therapy control group (N = 31). Subjects were assessed before and after intervention using mediator variables hypothesized according to the CBT model, as well as outcome variables and other socio-demographic and clinical measures. Results The results confirm that the effect of treatment on pain intensity was partially mediated by distress, catastrophizing, perceived control, distr…
Post-traumatic trigeminal neuropathy. A study of 63 cases.
2010
Introduction. Trigeminal neuropathy is most often secondary to trauma. The present study explores the underlying causes and the factors that influence recovery. Material and methods. A retrospective case study was made involving 63 patients with trigeminal neuropathy of traumatologic origin, subjected to follow-up for at least 12 months. Results. Fifty-four percent of all cases were diagnosed after mandibular third molar surgery. In 37 and 19 patients the sensory defect was located in the territory innervated by the mental and lingual nerve, respectively. Pain was reported in 57% of the cases, and particularly among the older patients. Regarding patient disability, quality of life was not a…
Correlation between oral health-related quality of life (OHQoL) and oral disorders in a Turkish patient population
2008
Objectives: The purpose of the present study is to determine the nature of the complaints that bring patients to our clinic and to what degree these complaints affect their quality of life (QoL). We also aimed to determine any associations between gender, education or harmful habits and each patient?s oral health-related quality of life (OHQoL). Methods: A total of 1090 patients, consisting of 651 females (59.7 %) and 439 males (40.3 %), were included in this study. Of these patients, 220 constituted healthy controls. Two patient-centered outcome measures, the 14 item OHIP-14 and the 16 item OHQoL-UK measures were used. Results: Most of the patients presented with toothache and caries (50.1…
Envelope approach for onlay bone grafting : preliminary surgical and prosthetic results
2009
Minimally invasive surgery principles have been applied to preprosthetic-implant surgery, and an adequate presurgical planning reduces morbidity in both harvesting and stabilization of the bone grafts. Objective: A new ?envelope? approach for onlay bone grafting at the alveolar process is presented, this avoids releasing incisions yet allowing adequate reconstruction of the defective site. Study design: To be included in the study the patient had to have an antero-posterior defect of the alveolar crest. Patient age and sex, location of the defect, type and size of graft, and complications appeared during follow up were recorded. Results: Ten consecutive patients (4 men and 6 women) have bee…
Open Reduction and Internal Fixation of Low Subcondylar Fractures of Mandible Through High Cervical Transmasseteric Anteroparotid Approach
2009
Purpose The aim of the present study was to evaluate the functional and radiologic results of low subcondylar fracture fixation with modus TCP plates (Medartis, Basel, Switzerland) using a high cervical transmasseteric anteroparotid approach. Materials and Methods A prospective study was designed, enrolling all minimum-aged 15-year-old echomorphology patients presenting with displaced low subcondylar fracture with occlusion disturbances during a 41-month period. All fractures were fixed with modus TCP plates using high cervical transmasseteric anteroparotid approach. All patients underwent immediate physiotherapy and a 6-week liquid and semiliquid feeding period. Clinical and radiologic exa…
Implant treatment in atrophic posterior mandibles: Vertical regeneration with block bone grafts versus implants with 5.5-mm intrabony length
2014
Purpose: To retrospectively compare the outcomes of implants placed in posterior mandibles vertically regenerated with onlay autogenous block bone grafts and short dental implants. Materials and Methods: Consecutive patients with vertical bone atrophy in edentulous mandibular posterior regions (7 to 8 mm of bone above the inferior alveolar nerve) were treated with either implants placed in regenerated bone using autologous block bone grafts (group 1) or short implants (with 5.5-mm intrabony length) in native bone (group 2) between 2005 and 2010 and followed for 12 months after loading. The procedure used was the established treatment protocol for this type of patient at the Oral Surgery Uni…
Surgical treatment and follow-up of solitary bone cyst of the mandible:a report of seven cases.
2001
We have operated on and followed up seven patients with simple mandibular bone cysts. The clinical data are shown in Table 1. All cysts were asymptomatic, and were found as a result of routine radiographs. They were all in dentulous areas in the mandible (5 in the anterior zone). Only case 5 gave a clear history of trauma in the region of the cyst 7 years before diagnosis. Vitality of the pulp of adjacent teeth was confirmed in all cases except case 6, in whom endodontic orthograde treatment of the teeth included in the lesion zone had previously been done. In all cases, the radiographs showed a unilocular radiotransparent lesion with clearly defined margins
Prevalence and distribution of odontogenic cysts in Sicily: 1986-2005.
2008
The objective of this study was to assess the prevalence of odontogenic cysts (OCs) in Sicily and evaluate their distribution during a 20-year period. A cross-sectional retrospective study was carried out in 1,310 cysts of the jaw diagnosed in 12,197 individuals, who consecutively attended the Odontostomatologic Clinic of Palermo from 1986 to 2005. 1,273 cysts were classified as odontogenic, whereas only 37 were non-odontogenic. In the former group, the most frequent lesions were radicular cysts (84.5%), followed by dentigerous OCs (11.4%). Inflammatory radicular cysts were observed more in male gender, younger age at diagnosis and anterior maxilla as site of presentation. Unlike dentigerou…
