Level of work stress and factors associated with bruxism in the military crew of the Peruvian Air Force

Abstract

Background: Military life leads to a great personal sacrifice and labor in the aircrew because they are constantly subjected to innumerable activities which have a great work pressure; therefore, the aim of this study was to determine the level of work stress associated with bruxism in the aircrew of the Peruvian Air Force. Methods: This was a cross-sectional study. A total of 204 crew members of the Peruvian Air Force from the Air Group were surveyed, and the stomatological clinical inspection was carried out. Each crew member was evaluated using the validated International Labor Organization-World Health Organization (ILO-WHO) Work Stress Scale, and clinical records were used to diagnose bruxism using the Smith and Knight wear index. Results: It was found that 93.7% (n ¼ 191) of the crew members were men and 6.3% (n ¼ 13) were women; and the percentage of intermediate-level stress was found to be high in the grade of non-commissioned officers, whereas in the officer grade, the level of stress was low. There was also a statistically significant association between the variables military grade, sex, and age group. The sub-officers presented a higher percentage in the category "with bruxism", while in the rank of officers the category of "non-bruxism" was the most prevalent. Conclusions: This study showed a statistically significant association between the variable bruxism and the level of work stress between the military aviators of the Peruvian Air Force (p<0.001).

Association between sleep bruxism and stress symptoms in adults: A systematic review and meta‐analysis

“…Ten analytical cross‐sectional studies were included. They were published in Brazil, 41‐43 Greece, 24 Indonesia, 44 Turkey, 45 Lithuania, 46 Peru, 47 Poland 48 and the United States 49 . They were published between 1980 and 2020.…”

“…The largest sample presented was 394 42 individuals and the smallest, 30 49 . In addition, only two of the included studies reported a priori calculations to estimate sample size 46,47 . Only three studies could be included for quantitative analysis 24,46,48 .…”

“…Two studies 44,46 assessed possible SB using only questionnaires. SB assessment was considered probable in eight studies 24,41‐43,45,47‐49 using clinical examination, of which four used an instrumental approach (EMG) to detected SB. None of the articles reported a definitive assessment using the standard test polysomnography.…”

Radiographic Correlation of Skeletal Maturation Using the Stages of Dental Calcification in a Peruvian Population

“…e time and speed of ossification are primarily affected by the socioeconomic development of the Peruvian population. In this way, in the future, it will prevent the appearance of bruxism and other parafunctions of the temporomandibular joint [29]. Of all the studies and procedures used for the evaluation of the stages of bone maturation and dental mineralization, the ones that have reached the most diffusion have been the qualitativedescriptive methods; this general method has the purpose of predicting and establishing the moment specific to the different states or events of sudden pubertal growth.…”
