What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Evaluation of the gingival abrasion (GA): Macro-relief scoring
Time Frame: 90 days
|
A first method for the evaluation of gingival abrasion (GA) will consist in a method of macro-relief scoring of gingival tissue as described previously by Perin et al. with skin tissue. This evaluation consists of acquiring macroscopic views of each investigated surface and then classifying them by observers according to a reference groups of defined abrasion intensity. This evaluation scoring, using photo grading technique, allow delayed and blinded scoring, independent of whole-subject appearance, thus decreasing subjectivity (Perin et al., 2000). Five items are evaluted for each picture : erythema, inflammation, bleeding, recession and erosion of the gingiva. All items are scored from 0 to 3, 3 representing the most significant impairment. |

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Comparison of gingival color;
Time Frame: 90 days
|
Comparison of gingival color between baseline and time point using photographs. The technique consists of acquiring macroscopic photographs of each gingival quadrant, including an internal colored reference chart in the vicinity of the photographed gingival tissue, at each time point. Next, using an image analysis software, each photograph will be calorimetrically reconverted to be recalibrated following the colored reference chart. Then, the coloring intensity in each zone of interest [marginal (cervical free gingiva, CFG), interdental (papillary free gingiva, PFG) and mid-gingival (attached gingiva, AG)] around each tooth in each quadrant, will be extracted by observers in a double-blind manner using the color picker tool. This method has already been applied to describe the intensity of skin coloring (red /green/blue component) as well as luminosity, the brightness and transparency (Musnier et al., 2004) and will be applied to each subject's gingival tissue. |
90 days
|
Presence of plaque -Plaque index, PI
Time Frame: 90 days
|
Plaque index (PI) described by Silness & Löe (Silness and Löe, 1964) uses 0 to 4 classes to assess the presence of plaque or not on six sites (mesio-buccal, buccal, disto-buccal, mesio-lingual, lingual, and disto-lingual) on all teeth, according to the following criteria: 0: absence of plaque; 1: non visible plaque but detectable with a probe; 2: visible plaque not detectable in the interproximal areas; 3: visible plaque in interdental spaces also.
|
90 days
|
Presence of inflammation BOP
Time Frame: 90 days
|
Gingival inflammation (GI) will be assessed as bleeding on marginal probing (BOP) using the index as described by Ainamo & Bay (Ainamo and Bay, 1975). GI uses a 0 to 3 scale to measure the presence of inflammation or not on six sites (mesio-buccal, buccal, disto-buccal, mesio-lingual, lingual, and disto-lingual) on all teeth, according to the following criteria: 0: absence of inflammation; 1: visible inflammation and no bleeding; 2: visible inflammation and bleeding on probing; 3: obvious inflammation and spontaneous bleeding. BOP is considered as dichotomous variable. BOP uses 0 and 1 scale. 0: no bleeding on probing; 1: bleeding on probing including 4 sites per tooth. The percentage of bleeding will be calculated as following: number of sites with bleeding / number of sites assessed X 100. |
90 days
|
Presence and/or amount of gingival recession (REC)
Time Frame: 90 days
|
Gingival margin recession will be measured from the cemento-enamel junction to the marginal position of the gingiva with PCP-UNC 15 (Hu-Friedy® Chicago, IL, USA) probe.
The measurements will be assessed at the middle of the buccal gingival recession.
|
90 days
|
Probing pocket depth (PD)
Time Frame: 90 days
|
PD will be measured before the test/control treatment by one and the same examiner by using the PCP-UNC 15 (Hu-Friedy® Chicago, IL, USA) probe throughout the study.
The probing depth will be assessed at the buccal aspects of teeth 16,14,13,11.
All measurements will be adjusted to the nearest 1.0 mm.
