Avaliação Do Limiar Auditivo Em Profissionais De Odontologia

Abstract

A perda auditiva induzida pelo ruído (PAIR) é uma das doenças do trabalho mais comuns em nosso meio. Os profissionais de odontologia trabalham em ambientes com alto nível de ruído, portanto, são passíveis de apresentarem PAIR. Dessa forma, o objetivo deste estudo foi avaliar os limiares auditivos por meio da audiometria tonal liminar (ATL) em profissionais de Odontologia. A população deste estudo foi composta por um total de 30 cirurgiões-dentistas que atuam há mais de três anos na profissão, com idade máxima de 45 anos. Todos os participantes foram submetidos aos seguintes procedimentos: anamnese, meatoscopia, ATL, logoaudiometria e imitanciometria. Os resultados mostraram que 27% dos odontólogos apresentaram queixa de zumbido, 30% de insônia e 37% dor de cabeça. Quanto aos resultados da ATL, 17% apresentaram alterações auditivas nas freqüências altas, isto é, 3 e/ou 4 e/ou 6 kHz. Os achados justificam a necessidade da realização de exame audiométrico periódico e o uso de protetores auriculares para a manutenção da saúde auditiva e à diminuição dos sintomas associados. Descritores: Efeitos do ruído, ruído ocupacional, perda auditiva e odontologia. Evaluation of the auditory thresholds in professionals of odontologia ABSTRATThe induced auditory loss for the noise (PAIR) is one of the illnesses of the work most common in our way. The professionals of Odontologia work in environments with high level of noise, therefore, they are passable to present PAIR. The objective of this study was to evaluate the The population of this study was composed by a total of 30 dentist surgeon who act more than have three years in the profession, with maximum age of 45 years. All the participants had been submitted to the following procedures: anamnese, meatoscopia, ATL, logoaudiometria and imitanciometria. The results had shown that 27% of the odontólogos had presented humming complaint, to 30% of sleeplessness and 37% migraine. How much to the results of ATL, 17% they had presented auditory alterations in the high frequencies, that is, 3 and/or 4 and/or 6 kHz. The findings justify the necessity of realization of a periodic audio metrical exam and the use of the auricular protectors for maintain auditory health and reduce the associated symptoms.

Caracterization from hearing thresholds from dentists in a poulation from Curitiba city / PR, Brazil

“…Other studies with dentists in Brazil were found also sensorioneural hearing losses, but in greater percentage than this, such as study in Paraná, with 85 surgeon dentists, were found 43,5% with hearing changes (9); in a study at Ribeirão Preto/SP (15) with 40 dentists of both genders, all of them with more than five years in profession, occurred 70% of hearing losses; and at Goiás, study with 228 dentists were found 31,58% with suggestive hearing changes of PAIR (16). In the research performed with 30 surgeon dentists in both of genders, it was found 17% of hearing changes in high frequencies (3 and/or 4 and/or 6kHz), lower percentage than this study (10). And, in a study performed in Belgium, the authors found hearing changes of 19,6% of dentists, especially in masculine gender (6).…”

“…In the Norm 17 -NR17 (3), which is based on Brazilian Norm -NBR n. 10152 4, it is established that for purposes of acoustic comfort, the maximum level of noise in dental offices must be of 45dBA to 50dBA. Research showed that clinic, the offices and dental laboratories presented high sound pressure levels which lead, in time, impairments to the health of the professionals who work there, like as PAIR among others (5)(6)(7)(8)(9)(10). Study in Brazil found high level pressure of sound in the odontological equipments from a brand largely used, namely: in high rotation 65 to 78,6 dBA, in the amalgam 65,8 to 68 dBA, in sucker of high-power 68,8 a 72 dBA, in ultrasound for cleaning teeth 75,8 to 88 dBA and in the low speed engine 69,8 to 72 dBA (11).…”

“…Among the non auditory symptoms associated to the noise exposure there are changes involving neurological system, circulatory systems, digestive system, endocrine system, immunological system and psyche (13). In study of 30 dental surgeons, of both of genders, it was found complaints possibly associated to exposure to noise: buzz (37%), insomnia (30%), headache (27%) and nausea (20%) (10).…”

“…Sabendo que os consultórios e clínicas odontológicas apresentam elevados níveis de pressão sonora, os profissionais podem, com o tempo, apresentar comprometimentos na saúde auditiva (GONÇALVES et. al., 2010); (LELO et. al., 2009).…”
