Risk factors of gingival injuries in plaque removal by toothbrushing






Proceedings of the Finnish Dental Society. Suomen Hammaslaakariseuran Toimituksia 84 Suppl 1-2: 1-64

Risk factors of gingival injuries in plaque removal by toothbrushing

The present investigation was designed to evaluate the importance of toothbrush bristle thickness, bristle tuft arrangement, toothbrush grip and dentifrice in the origin of acute gingival toothbrushing injuries and in plaque removal Manual and electric toothbrushes were also compared in this respect. Evaluation was carried out by experimental brushings performed by a dental hygienist; a manual and an electric brush was also used by the female subjects themselves. The influence of gingival inflammation and sex steroid hormones on the susceptibility of gingival tissues to trauma were also evaluated. The gingival injuries resulting from experimental toothbrushing were identified with the naked eye, and the reliability of the visual distinction was confirmed by scanning electron microscopic (SEM) examination. Eighty-nine per cent of the lesions were verified as traumatic by SEM examination, which was accurate enough for the studies.
