Epidemiological analysis on 2375 patients with TMJ disorders: basic statistical aspects

Abstract

SummaryThe aim of this work was to present data from a large sample of patients with Temporo-Mandibular Disorders (TMD) in order to clarify some aspects of the development of pathological conditions that affect large parts of the population. This preliminary work put in relation, through an epidemiological evaluation, anamnestic and clinical data collected from a sample of 2375 patients affected by TMD. Personal data were provided by questionnaire (age, sex, status, etc.), while clinical data were collected following a specific medical chart compiled in accordance with international criteria for TMD. An analysis of these data clearly showed that there were large quantities of variables involved in these disorders and which occur with a wide variety possible of clinical signs. This complexity, in accordance with the current knowledge that it is not able to clarify the etiology of these disorders, makes intricate both diagnostic then therapeutic aspects. You would find in front of a multifactorial systemic disease that, interfering with the individual bioavailability, exposes him to the possibility of perceiving noxious stimuli which otherwise would not able to reach the pain threshold. To support this hypothesis is the data founded in this report that showed how many patients suffered, at the same time, by muscle and spinal pain associated to headache, pain that occur with high frequency from the same side. The presence of these painful conditions tends to underestimate the dysfunctional problems even if they occur with greater clinical prevalence. Further research should be carried out to clarify these controversial issues.

Prevalence of temporomandibular disorders in postmenopausal women and relationship with pain and HRT

“…These conditions are frequently related to other structures of the body, complicating their classification, diagnosis, and treatment 1,2,3 . The prevalence of TMD symptoms ranges from 16% to 59% in studies of non-patient populations 4,5 .…”

Splint-assisted disc plication surgery

“…Studies have quoted variable levels of trauma and dental treatment previous to the development of symptoms. Some patients also have an element of systemic disease such as joint hypermobility or arthritis with one study quoting the figure at 13.1% (5). Given a lack of consensus regarding best treatment methods, the American Association of Oral and Maxillofacial Surgeons (AAOMS) issued a statement regarding TMD syndrome.…”

Estudo da correlação entre estalo articular e posição do disco da articulação temporomandibular pela ressonância magnética em pacientes diagnosticados com disfunção temporomandibular

“…A alta prevalência do gênero feminino em indivíduos diagnosticados com DTM é bastante relatada na literatura (Agerberg;Bergenholtz, 1989;Salonen et al, 1990;Katzberg et al, 1996;Machado et al, 2009;Gonçalves et al, 2010;Slade et al, 2011;Bagis et al, 2012;Di Paolo et al, 2013), o que também foi observado na amostra desse estudo onde do total de pacientes examinados 70% (42/60) pertenciam ao sexo feminino.…”

“…Apesar de muitos estudos (Agerberg;Bergenholtz, 1989;Salonen et al, 1990;Katzberg et al, 1996;Machado et al, 2009;Gonçalves et al, 2010;Slade et al, 2011;Bagis et al, 2012;Di Paolo et al, 2013) afirmarem que há uma diferença entre intensidade do sinal do disco articular da ATM e o pseudodisco na IRM, muitas vezes essa diferença é imperceptível no exame.…”
