Ruído Ocupacional, Audição e Qualidade de Vida em Dentistas

Abstract

ABSTRACT Introduction Workers with excessive noise exposure can develop problems related to general health, hearing and have changes in quality of life, with Noise-Induced Hearing Loss (NIHL) being the most common change associated with hearing. Dentists, when using different types of equipment for clinical and surgical procedures, end up being exposed to noise daily. Hearing loss is associated with decreased life quality, including an increased risk of loneliness, isolation and a decline in functional fitness. Considering that hearing is fundamental in the socialization process and, consequently, for oral communication, any and all changes in auditory perception can trigger problems in social interaction with a negative impact on people’s lives. Objective To analyse the impact of noise on hearing and life quality of dentists in Paraná. Methods This is a descriptive observational, cross-sectional study carried out with forty dentists from southern Brazil. The research subjects underwent basic audiological evaluation and high frequency audiometry, in addition to answering two questionnaires, one about life quality (SF-36) and the other with data about the working conditions, knowledge and perceptions of dentists regarding the exposure to noise at work. Results Auditory changes suggestive of being induced by noise were observed in 15% of dentists. In high frequency audiometry, auditory alterations occurred in six professionals, and in four of them there was bilateral alteration. The SF-36 indicated median values of 62.57 for general health and 64 for vitality; 100 being the maximum score. It was found that 52.5% of dentists are aware of the effects of noise exposure on health, but only 5% declared using ear protectors during the exercise of their profession. Conclusion Early awareness of the effects of noise would bring more comfort and life quality to dentists, as well as less hearing problems.
