“…In the present study we intended to observe whether brushing with a new toothbrush, a daily and mandatory behavior, can produce significant changes in the vascular microdynamics of the marginal gingiva of adolescents. In addition to classical tests, periodontal probing depth and gingival index, we used laser Doppler flowmetry, knowing that this is a noninvasive, objective method that can identify changes in blood flow after brushing [ 2 , 3 ] in real time and before the occurrence of clinical signs.…”

“…The effect of tooth brushing on gingival blood flow has been a topic of interest for researchers, being studied in both animals and human subjects. In 1981, Nuki et al [ 2 ] performed a study on dogs and recorded the evolution of blood flow to the capillaries in the attached gingiva. For this purpose, they used measurements of the clearance of a diffusible isotope such as 133Xe, which are known to reflect changes in the blood flow rate in capillaries.…”

It is well-known that proper tooth brushing has the effect of stimulating microcirculation in a healthy gingiva. The aim of this study was to evaluate the microcirculation dynamics at the level of healthy marginal gingiva in adolescents after changing their toothbrush. Three evaluation instruments were employed to assess and quantify the effects on the marginal gingiva: the periodontal probing depth (PD), gingival index (GI) and laser Doppler flowmetry (LDF). A total of 12 adolescents, aged between 15 and 20, were enrolled in the study, resulting in a total of 72 frontal upper teeth for PD and GI and 48 gingival interdental sites for LDF assessment. For each measurement, the pulp blood flow signal was recorded for 1 min and represented as a pulsatory signal. Data were collected in four moments: before the toothbrush changed and 24 h, 7 days and 14 days after. For the statistical analysis, the nonparametric Friedman test was applied for comparisons between more than two pair numeric series and for comparisons between two sets of pair values without Gaussian distribution, the Wilcoxon signed-rank test was applied. The paired t test was used for two sets of normally distributed paired values. The results showed that using a new toothbrush in the adolescent population with healthy gingiva can induce statistically significant increases in gingival blood flow, which remain at a high level even at two weeks. The GI also increases significantly at 7 days and 14 days, while the periodontal PD does not change significantly.

“…This, as well, may be due to the brushing force which varies in the different regions of the dental arch (Bjom & Lindhe 1966, Kakudo et al 1969, Heath & Wilson 1974, Mierau & Spindler 1984. Some authors (Nuki et al 1981, White 1983) have proposed that dental plaque can be removed more effectively by increasing the brushing force. According to our results such improved cleanness is achieved at the expense of gingival trauma.…”

The aim of the present study was to determine whether the type of toothbrush grip affects gingival injury during brushing. The cleanness of the teeth achieved by use of 2 different brush grips was also evaluated. The teeth of 13 dental nurse students were brushed by a dental hygienist. Using the split mouth technique, one side of the mouth was brushed for 2 min holding the toothbrush with a pen grip and the other side for another 2 min using the palm grip. The procedure was repeated 11 days later with reversed brush grips on the 2 sides of the jaws. More gingival injuries were found when the toothbrush was held with the palm grip than with the pen grip. This difference was statistically significant (P less than 0.01). No statistically significant difference were observed between corresponding plaque scores as measured according to the PLQ-index, irrespective of whether the plaque scores were presented as plaque remaining after experimental brushing or as the difference between the PLQ scores before and after brushing.

“…The effect of mechanical stimulation on gingival tissue has been shown to promote gingival keratinization, which may increase the defensive function of gingival tissue (Caffesse et al, 1982), The immediate effect of gingival stimulation on improvement of microcircuiatory function has also been investigated. Temperature in the attached and sulcular gingiva increased after toothbrush stimulation (Kroone et al, 1980), This finding suggested that dilation of the gingival microvasculature resulted in an increase in gingival blood flow, A small increase in gingival blood flow was found after stimulation of attached gingiva in dogs using the '-'"'Xe clearance method (Nuki et al, 1981),…”

The effect of mechanical toothbrush stimulation on gingival microcirculatory functions was examined with and without removal of supragingival plaque in inflamed gingiva of 6 dogs. After removal of the ligatures, 4 treatment modalities: mechanical stimulation by vibration (MS), removal of supragingival plaque (PR), combination (MS+PR) and no treatment (NT), were administered to each quadrant for 2 weeks. Both quadrants with plaque removal showed a marked decrease in the gingival index score, while slight and moderate decreases were observed in NT and MS quadrants, respectively. Changes in gingival crevicular fluid flow, pocket oxygen tension and hemoglobin oxygen saturation in the gingiva were significant in the MS, PR and MS+PR quadrants. Significant treatment-by-time effects were found for all of the parameters of microcirculatory function between NT and MS quadrants, and gingival crevicular fluid flow between PR and MS+PR quadrants, respectively. These findings suggest that mechanical stimulation with a toothbrush may offer an additional benefit to gingival microcirculatory functions in inflamed gingiva.
