Abstract

This study explored ethnic differences in perceptions of pain and the need for local anesthesia for tooth drilling among age- and gender-matched Anglo-American, Mandarin Chinese, and Scandinavian dentists (n = 129) and adult patients (n = 396) using a systematic qualitative research strategy. Semistructured qualitative interviews determined: (a) the relative frequency of use or nonuse of anesthetic for similarly specified tooth drilling, (b) the reasons for nonuse of anesthetic as reported by dentists about their patients, and (c) the distribution of reasons for not using anesthetic. American dentists (n = 51) reported that about 1% of their adult patients did not use anesthetic compared with 90% among Chinese (n = 31) and 37.5% among Scandinavian dentists (n = 40). Of patients, Americans (n = 112) reported 6% nonuse of anesthetic for tooth drilling compared with 90% of 159 Chinese and 54% of 125 Scandinavians. Reasons among Anglo-Americans and Scandinavians were similar (ranked): the sensation was tolerable, to avoid numb feelings afterwards, and fear of injections. Danish patients were an exception; the fact that they had paid extra and out-of-pocket for anesthetic ranked second. In contrast, Chinese dentists made their decisions not to use anesthetics because they explained drilling as only a suan or "sourish" sensation, whereas injections were described as "painful." It was concluded that ethnic pain beliefs and differences in health-care systems are powerful psychosocial variables that affect pain perception and the perceived need for anesthetic.
