Previous studies of dental devices (toothbrushes, dentures, and protective athletic mouthguards) have demonstrated microbial contamination of these devices and possible transmission of infectious diseases to the users. Since woodwind and brass instruments come into intimate contact with the musician's oral cavity and often are passed from student to student without sanitization, the question arises as to whether these instruments are contaminated and can transmit microbial diseases. The purpose of this study was to determine if woodwind and brass instruments and/or their cases harbor opportunistic, pathogenic, or allergenic microorganisms that can be transmitted to the musician. The internal components of woodwind and brass instruments harbored opportunistic, pathogenic, and/or allergenic microorganisms. The highest concentrations of microorganisms were found consistently at the mouthpiece end, but there was evidence of contamination throughout the instruments and their cases. The close proximity of contaminated mouthpieces to the oral cavity could facilitate local and systemic dissemination of the resident opportunistic, pathogenic, and/or allergenic microorganisms. General dentists should determine whether patients play a brass or woodwind instrument and be aware of the possible impact of this activity on the oral cavity and the entire body.
先前对牙科器械（牙刷、假牙和运动防护牙套）的研究表明，这些器械存在微生物污染，并且可能将传染病传播给使用者。由于木管乐器和铜管乐器会与演奏者的口腔密切接触，并且常常在学生之间传递而不进行消毒，因此就产生了这些乐器是否被污染以及是否会传播微生物疾病的问题。本研究的目的是确定木管乐器和铜管乐器及其琴盒是否携带可传播给演奏者的机会性、致病性或变应原性微生物。木管乐器和铜管乐器的内部部件携带了机会性、致病性和/或变应原性微生物。始终在吹口一端发现最高浓度的微生物，但有证据表明整个乐器及其琴盒都受到了污染。受污染的吹口与口腔距离很近，可能会促进常住的机会性、致病性和/或变应原性微生物在局部和全身的传播。普通牙医应确定患者是否演奏铜管乐器或木管乐器，并了解这种活动对口腔和全身可能产生的影响。
