Oral Findings In Glassblowers
COMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY(1980)
摘要
Oral changes related to the occupation of glassblowing have been examined in 74 Danish glassblowers, consisting of 44 active glassblowers (Group 1) and 30 past glassblowers (Group 2). In addition, 15 non-glassblowers (Group 3) were examined. All three groups worked in the same department of mouth-blown glassware in Holmegaard's Glassworks. White patches of the buccal mucosa occurred in 23% of active glassblowers, but did not occur among past or non-glassblowers. Histologically, the white lesions revealed morsicatio buccarum-like changes. The lesions are reversible and should be distinguished from leukoplakias. The term "glassblower's white patch" is suggested. Furthermore black discolorations of vermillion border and front teeth occured in 30% and 62%, respectively, of active glassblowers. Tooth fractures, mostly enamel fractures, caused by the blowpipe were found in 43% of active glassblowers and 19% of past glassblowers.
