Prevalence of oral soft and hard tissue lesions related to mechanical toothcleansing procedures

Pilot study on dental erosion in a Norwegian electrolytic zinc factory

In 12 workers in a Norwegian factory using electrolytic methods to extract zinc, a relationship was found to exist between degree of erosion, number of teeth affected and the length of service. The prevalence of caries, abrasion and attrition was not higher than in comparable population groups. The correlation between diagnosis of erosion based on clinical examination, and diagnosis based on evaluation of color slides was good.

Traumatization of teeth and gingiva related to habitual tooth cleaning procedures

Traumatization of oral hard and soft tissues connected with mechanical oral hygiene procedures has been reported in the dental literature. Definitions, classifications and localization of such lesions are listed, and in vivo and in vitro experiments within the field are reviewed. Existing literature suggests that hard tissue lesions are mainly due to abrasives in dentifrices, whereas gingival lesions may be caused by toothbrushing per se. Factual knowledge about the prevalence, severity and clinical significance, as well as relevant and reliable experiments, is scarce and further research on these topics seems to be indicated.
