The relationship between orthodontic treatment and temporomandibular disorders: A dental specialists’ perspective

Abstract

Introduction: The relationship between temporomandibular disorders (TMDs) and orthodontic treatment/malocclusion has changed from a cause-and-effect association to an idea without sufficient evidence. Objective: This survey was designed to assess the beliefs of different disciplines - orthodontists, oral surgeons, and oral medicine specialists - on the relationship between TMDs and orthodontic treatment, with regard to treatment, prevention and etiology of TMDs. Method: A survey in the form of questionnaire was designed and distributed to 180 orthodontists, 193 oral surgeons and 125 oral medicine specialists actively involved in treating TMDs. The questionnaire aimed to collect basic information about each participant and their beliefs, and clinical management of patients with TMDs. Results: Halve of the responding orthodontists and most of the oral surgeons (69.9%) were male participants, whereas the majority of oral medicine specialists (83.3%) were female respondents. The participants’ age ranged from 29 to 58 years. The majority of orthodontists believes that there is no relationship between orthodontic treatment and TMDs, and that orthodontic treatment does not provoke TMDs or prevent the onset of the disorder. However, oral surgeons and oral medicine specialists have different and conflicting opinions. Most surgeons tended to treat those patients, while most of the other two disciplines tended to seek an interdisciplinary approach. Chi-square test was done to find an association between the referral status and specialists’ experience, and to compare between the different disciplines’ belief. Conclusions: Orthodontist’s beliefs were in accordance with the scientific evidence, whereas most oral surgeons and oral medicine specialist believed that orthodontic treatment may provoke TMDs. Therefore, continuing program series development is important to embrace the concept of the multidisciplinary team approach and improve the health care and quality of life for those patients.

The Impact of Temporomandibular Disorders on Orthodontic Management: A Systematic Review and Meta-Analysis

“…At the end of the search protocol, nine studies [ 15 - 23 ] that were in accordance with our objectives were deemed appropriate for inclusion in this review. Table 1 provides information on these studies conducted in different regions of the world, their investigation year, sample size, age range of participants, and gender ratio.…”

“…The studies included in the table were conducted in different regions of the world, such as Baghdad [ 15 ], Israel [ 16 ], Italy and Spain [ 17 ], Portugal [ 18 ], Poland [ 19 ], China [ 20 , 22 ], Singapore [ 21 ], and South Korea [ 23 ]. This regional diversity allows for a more comprehensive evaluation of the topic and provides a global perspective.…”

“…Table 2 , on the other hand, presents scientific data on four different studies that focused on TMDs and their impact on orthodontic management. The first study by Al-Groosh et al [ 15 ] employed a cross-sectional protocol to assess the knowledge regarding TMD treatment using an orthodontic approach among clinicians. The study involved three groups of clinicians, including oral medicine specialists, orthodontists, and oral surgeons.…”

Can the Autogenous Nanofat Injection Improve the Symptoms of Patients With Temporomandibular Joint Internal Derangement? A Prospective Observational Clinical Study

“…The temporomandibular joint (TMJ) is prone to several disease states affecting any one of its anatomical components; the currently favored term for problems associated with the TMJ is “temporomandibular disorder(TMD)”; this is a significant public health issue that affects between 26% and 46% of young adults 1,2 …”

“…T he temporomandibular joint (TMJ) is prone to several disease states affecting any one of its anatomical components; the currently favored term for problems associated with the TMJ is "temporomandibular disorder(TMD)"; this is a significant public health issue that affects between 26% and 46% of young adults. 1,2 Internal derangement (ID) is the most frequently occurring among the TMDs, including 41.1% of TMD patients. It represents a disruption within TMJ internal structures in which there is a displacement of the disc from its normal functional relationship with the articular portion of the temporal bone and mandibular condyle, 3 thus can be attributed to multiple factors such as micro or macro trauma, bruxism, joint laxity, and changes in the lubrication systems of joints.…”
