Introducción: La disfunción temporomandibular (DTM) puede estar ocasionada por numerosos factores, como maloclusiones, traumatismos, bruxismo, así como por estrés y depresión. Esta última se caracteriza por un estado de profunda tristeza, abatimiento e infelicidad. Ambos trastornos pueden presentarse en la adolescencia, cuando se crean las pautas de lo que será la persona en la adultez, tanto en el aspecto psicológico como en el emocional y el anatomofisiológico.

The aim of this study was to evaluate the mixture of Calcium Sulfate and Plasma Rich in Growth Factors (CaSO4 + PRGF) as a bone-graft substitute in extracted mandibular third molar (MTM) alveoli during a 4-month period. Bilateral MTM extractions were performed in 10 patients (18–25 years) at the Oral-Surgery-Clinic of the Universidad Autónoma de Yucatán (UADY). A CaSO4 + PRGF mixture was placed in the right alveolus (Experimental Group (EG)) and a natural blood clot in the left (Control Group (CG)). Monthly X-ray controls were performed using a gray scale to measure Bone Regeneration (BR). A non-parametric Sign Test was used to evaluate Radiopacity/Bone Regeneration (Ro/BR) over 4 months, and a Friedman’s non-parametric test was used for intra-group analysis over these months. The study was approved by the Centro de Investigaciones Regionales (Dr. Hideyo Noguchi, UADY Bioethics Committee, ID 0026-2015). Using a non-parametric test of the sign, the EG showed significant difference of Ro/BR between groups p = 0.002 (p < 0.05). Significant differences were observed in all quadrants and areas p = 0.002 (p < 0.05) except in area A in month 4 (p = 0.016), which could be explained by its being the closest to native bone. EG CaSO4 + PRGF showed a higher degree of bone regeneration compared to CG.

Bruxism is the habit of squeezing and grinding the dental organs (ODs), with dental contacts that have no purpose. The Oral Health-Related Quality of Life (OHRQoL) is defined as a multidimensional aspect that reflects the comfort of the individual in relation to their physiological and psychological functions, of the state of oral health. To determine the relationship between probable bruxism and OHRQoL in patients who came for care at the University Unit of Social Insertion (UUIS) of the Autonomous University of Yucatán (UADY), México from September 2019 to January 2020. Observational, analytical of case controls and cross-sectional. Two instruments were applied to 70 patients: the OHIP-EE-14 (validated by Castrejón-Pérez R.C., Borges-Yañez S.A.) and a questionnaire prepared by Mendiburu-Zavala C., based on Ordoñez Plaza et al., González-Emsoto et al., and De La Hoz-Aizpurua et al for the diagnosis of probable bruxism. Descriptive and inferential statistics were used. 47.1% (n=33) did present probable bruxism (CPB) and 52.9% (n=37) did not (SPB). The most frequent age group was 18-35 years old, with 67.2% (n=47), 34.3% (n=24) CPB. The most frequent circadian manifestation was waking with 49% (n=16). Those of CPB, a mean of 20.45±7.95 was obtained in the OHIP-EE-14 for the OHRQoL and SPB score, the mean was 7.81±4.84.  There are statistically significant differences between CPB and SPB patients (p<.001). The probable bruxism does affect the OHRQoL  level.
