Due to daily work, difficulties arise in the musculoskeletal system that affect health within the workplace, especially in the dental field, as the dentist must use ergonomic factors to perform their work correctly. The aim of this study was to establish the dependence between the severity of musculoskeletal disorders and ergonomic factors in dental practice in the Ventanilla district, 2021. In this quantitative, descriptive, and cross-sectional study, a simple random probabilistic sample of 120 licensed and registered dentists was selected, using a questionnaire with virtual questions through an online form. The results indicate that 7 dentists experience severe discomfort (>4 hours) while sitting in the ergonomic chair. It was determined that, among the sociodemographic characteristics of age, weight, sex, and height, 42.5% (51) were female, and 57.5% (69) were male, with ages ranging from 24 to 51 years and older. It was concluded that multiple ergonomic factors contribute to these injuries in the professional field, and a correlation between the injuries was found.

Poor posture today represents one of the major ailments that significantly affects people's health, due to the structural imbalance that occurs when there is an alteration in body biomechanics, and its relationship with the development of occupational diseases such as painful musculoskeletal disorders or temporomandibular joint disorders, which, according to epidemiological reports, indicate a current prevalence of 45% in the global population. Objective: The general objective of this research is to evaluate the relationship between body posture and TMJ disorders in an adult population – 2023. Materials and Methods: The study was observational, cross-sectional, and prospective, with the population consisting of 90 students from Universidad Norbert Wiener. The technique was observational, and a data collection form was used to record body posture using the New York Posture Test (NYPR) and the Fonseca Anamnestic Index through a survey technique to assess temporomandibular joint disorders. Results: The description of body posture in the evaluated adult population revealed that 77.8% had good body posture, and 22.2% had poor body posture. The description of TMJ disorders showed that 68.9% had no discomfort, while 31.1% did. It was concluded that there is a statistically significant relationship between body posture and TMJ disorders in the evaluated adult population.
