Resumen

LARENAS-CALDERON, Claudia; SAAVEDRA-LAYERA, Loreto; VERGARA-NUNEZ, Cristian  y  SPANO-PEREZ, Natalia. Prevalence of signs and symptoms of temporomandibular disorders before orthodontic treatment in a population of Santiago, Chile. Rev. Clin. Periodoncia Implantol. Rehabil. Oral [online]. 2018, vol.11, n.3, pp.160-163. ISSN 0719-0107.  http://dx.doi.org/10.4067/S0719-01072018000300160.

Objective:

The aim of this study was to establish the prevalence of signs and symptoms of temporomandibular disorders (TMD) in patients with malocclusion.

Materials and methods:

Cross-sectional descriptive study. A total of 951 clinical records were reviewed, of patients admitted in the Postgraduate Program of Orthodontia from the Faculty of Dentistry of the University of Chile, between the years 2013 and 2015. The programs Excel 2013 and Stata v. 12 were used, and for the comparison between the age groups the statistical test of Kruskall Wallis was used.

Results:

Of the total number of patients with malocclusion, 43.85% had at least one sign or symptom of TMD, being the mandibular deviation the most prevalent sign with 43.22%, followed by joint noise with 12.62%. Pain was the least prevalent symptom with 2%. The adults group had the most prevalence of signs and symptoms of TMD. There was no statistical difference between genders.

Conclusion:

Since TMD signs and symptoms are such a common condition in patients with malocclusion, the assessment of TMJ is necessary to consider when planning an orthodontic treatment, to establish an adequate treatment plan.
