“…Dental plaque forms gradually after cleaning of the tooth surfaces [34]. Future research would therefore preferably comprise a longitudinal study to monitor the changes in the red fluorescence of plaque over time, which would then aid in a complete understanding of the correlation between the fluorescence and the matured plaque.…”

ObjectivesThe aim of this cross-sectional study was to assess the correlation between dental plaque scores determined by the measurement of red autofluorescence or by visualization with a two-tone solution. Clinical photographs were used for this study.Materials and methodsOvernight plaque from the anterior teeth of 48 participants was assessed for red fluorescence on photographs (taken with a QLF-camera) using a modified Quigley & Hein (mQH) index. A two-tone disclosing solution was applied. Total disclosed plaque was clinically assessed using the mQH index. In addition, total and blue disclosed plaque was scored on clinical photographs using the mQH index.ResultsA strong correlation was observed between the total disclosed plaque scored on photographs and the clinical scores (r = 0.70 at site level; r = 0.88 at subject level). The correlation between red fluorescent plaque and total plaque, as assessed on the photographs, was moderate to strong and significant (r = 0.50 at the site level; r = 0.70 at the subject level), with the total plaque scores consistently higher than the red fluorescent plaque scores. The correlation between red fluorescent plaque and blue disclosed plaque was weak to moderate and significant (r = 0.30 at the site level; r = 0.50 at the subject level).ConclusionsPlaque, as scored on white-light photographs, corresponds well with clinically assessed plaque. A weak to moderate correlation between red fluorescing plaque and total disclosed plaque or blue disclosed plaque was found.Clinical relevanceWhat at present is considered to be matured dental plaque, which appears blue following the application of a two-tone disclosing solution, is not in agreement with red fluorescent dental plaque assessment.

“…The incline of the PI during the four consecutive days as well as the general value of the PI values was in accordance with published findings [1,2,11,16,18], as was the retardation of the plaque accumulation with CHX [1,2,4,11,16,18], although in these studies other PI values were used. Plaque accumulation on the teeth surfaces could be assessed even more precisely by knowing the percentage of Table 2 Mean (±SD) values of the plaque index (PI), the plaque area as a percentage (PA%) and the vitality of plaque (VF%) on day 4, and significant differences in comparison with the placebo solution (ns not significant; *P≤0.05, **P≤0.01, ***P≤0.001 [20] considered the different PI values to not be exact enough and used also the calculation of the relative PA for a more detailed analysis of plaque growth for a period of 96 h. For evaluation, a planimeter was used by these authors. The amount of plaque was given as a percentage of the total buccal surface just like performed in the present study.…”

The aim of this clinical pilot study was to compare the effect of tea tree oil with the effect of water and chlorhexidine on supragingival plaque formation and vitality. Eight subjects were asked to refrain from any kind of mechanical oral hygiene for 4 days after professional tooth cleaning (day 0), and to rinse with water instead for 1 week, with chlorhexidine in a second and tea tree oil in a third test week. The plaque index (PI), which was evaluated daily (days 1-4), served as a clinical control parameter. On the last day of the study (day 4), the plaque covering the front teeth was stained, photographed, and therefrom the plaque area (PA; %) was estimated using a digital measuring system. Each day of the study (days 1-4), the sampled plaque was examined using a vital fluorescence technique. Tea tree oil reduced neither the clinical parameters (PI and PA) nor the vitality of the plaque flora significantly. Within the limitations of the study design, it was determined that a solution with tea tree oil--utilized as ordinary mouthwash--has no positive effect on the quantity or quality of supragingival plaque.

“…While few studies have been published that describe the plaque formation in various parts of the dentition by means of a plaque index or planimetric measurements of the plaque-covered area of teeth [Quirynen and van Steenberghe, 1989;Furuichi et al, 1992], to date no studies have determined the vitality state in the different layers of a biofilm at different locations in a systematic fashion. Therefore comparisons concerning vitality values can only be made in general.…”

Individual Vitality Pattern of in situ Dental Biofilms at Different Locations in the Oral Cavity

et al. 2004

The aim of the study was to examine the three-dimensional vitality structure of dental biofilms grown simultaneously at different locations in the oral cavity over a 48-hour period. Eight healthy volunteers wore special acrylic appliances. On each buccal side of the upper and the lower jaw three glass slabs were inserted, allowing for growth of a biofilm mimicking approximal plaque. After 48 h, the specimens were removed and biofilms were stained using two fluorescent dyes which selectively stain vital bacteria green and dead bacteria red. Under the confocal laser scanning microscope optical sections of 1 µm throughout the biofilm were made. To assess the vitality values (proportion of vital bacteria) of the whole biofilm as well as the vitality distribution in the different plaque sections an image analysis program was used. Plaque from the different locations revealed mean vitality values between 64.4 and 75.7% in the upper jaw and between 64.3 and 76.8% in the lower jaw, which were not statistically different. However, a great variation of the vitality values for the different layers and among the 8 subjects was found. Nevertheless, the analysis of the data of each single volunteer revealed a very similar vitality pattern in all twelve locations.
