Abstract

Work-related exposures affecting oral health are important factors of morbidity and decreased quality of life, which may emerge from numerous physical, chemical, or mental occupational exposures. Copper (Cu) is an important trace element, however, it may also cause allergies, depose and accumulate in the body, leading to acute and chronic toxicity. In the present report, we describe a rare phenomenon found during the examination of two professional brass players, after incidentally noting an artefact during magnetic resonance imaging (MRI) scans, which were performed to monitor bone healing after bone augmentation procedures in an unrelated clinical study. During a detailed workup of patient characteristics, data on medical history, lifestyle, professional habits related to playing the instrument, and oral health status were collected. Overall, both patients presented with similar histories, and the differences from the context of this study were not relevant; however, both brass players were using an uncoated Cu mouthpiece for over 15 years. Based on the imaging findings (a shadow in the area of the lips on the MRI images) and the organoleptic evaluation of the lips and mucosa of the individuals (temporary faint green discoloration), it is most likely that the brass players were affected by oxidized Cu accumulation in the lip. In contrast to several professions, musicians are usually not required by law to attend obligatory occupational health check-ups, which may facilitate the occurrence of such exposures in musicians. Clinicians should be on the lookout for brass players involved in the profession for a long time, who may have used the mouthpieces for an extended period of time, in addition to musicians affected by Wilson's disease. In patients affected by this phenomenon, diagnostics of oral cancer and prosthodontic procedures may be cumbersome, due to the detrimental impact on the utility of MRI imaging from artefact-formation and scattering.

Abstract

Introduction: A wind instrumentalist was diagnosed with a periapical lesion on tooth 21. The prosthetic rehabilitation options were considered with respect to the embouchure mechanism of the saxophonist. The underlying mechanism associated with the embouchure of the saxophone player was observed in this particular case in order to understand if asymmetrical forces were transmitted to the upper central incisors. Periapical lesions can be harmful to the oral health of musicians. The treatment options thus have to be taken into consideration with special focus on the need for oral rehabilitation on the anterior maxilla. Material and Methods: The patient underwent a radiographic examination with a panoramic X-ray. Subsequently, two piezoresistive sensors (FlexiForce&trade, ) were placed on the upper surface of the mouthpiece in order to quantify the pressure applied to the central incisors during the embouchure. In order to understand the values involved during this procedure, the saxophone player was required to play three different notes at different pitches: high, medium, and low. This procedure was repeated three times for each pitch in order to obtain a medium value for each note. Signal acquisition was obtained within software developed for this purpose, with the voltage output observed in LabView 2011&reg, Results: The panoramic X-ray showed a periapical lesion with the characteristics of a radicular cyst on tooth 21. The FlexiForce&trade, piezoresistive sensors allowed us to find that greater force (kg) was being applied to tooth 11 in comparison to tooth 21 during the embouchure mechanism. Conclusions: The sensors used in this research are acceptable for identifying the tooth where the greatest pressure is applied during the mouthpiece stabilization. In the case of executing an oral rehabilitation procedure for wind instrumentalists, a clinical examination can be complemented with the aid of bioengineering and the inherent development of sensor technology in order to better understand the embouchure mechanism. Likewise, the prosthetic rehabilitation should be taken into consideration in order to provide minimal changes to the musician&rsquo, s performance.
