Trial Outcomes & Findings for A Clinical Study to Evaluate the Efficacy of a Range of Dental/Denture Products for Improved Oral Health in Partial Denture Wearers (NCT NCT04290624)

NCT ID: NCT04290624

Last Updated: 2023-11-18

Results Overview

The BI assesses the number of bleeding points elicited on probing as a measure of gingival condition. To perform the assessment, a probe was inserted into the gingival crevice to a depth of approximately 1 millimeter \[mm\] and then run around the tooth (at approximately 60 degrees to the long axis of the tooth) gently stretching the epithelium while sweeping from interproximal to interproximal along the sulcular epithelium. Three scores were recorded bucally/labially (distal, body, mesial sites) and 3 scores lingually/palatally (distal, body, mesial sites). All scorable teeth in 1 quadrant were probed first (approximately 30 seconds) before recording the number of gingival units which bled. The BI scoring included 3-point scale ranged from 0 to 2, where 0=no bleeding, 1=bleeding within 30 seconds of probing, 2=bleeding immediately on probing. Sites with a score of 1 or 2 were classified as 'bleeding' sites. Higher score indicates worst outcome.

Measure
Intervention Group
Participants were instructed to use a dentifrice containing 0.454 percent (%) weight/weight (w/w) stannous fluoride, COREGA denture foaming cleanser and mouth rinse containing 90 parts per million (ppm) sodium fluoride. Participants brushed with a strip of the dentifrice (full brush head) applied to the full length of the toothbrush head for 2 minutes followed by 2 pumps of denture cleanser foam brushed onto removable partial denture (RPD) for 90 seconds and 10 milliliters (ml) of mouth rinse for swished around the mouth for 1 minute. Participants applied all these products topically orally twice daily (morning and evening) for 12 weeks.
Non-intervention Group
Participants did not receive any products and continued with their existing dental/denture hygiene practices and were instructed not to make changes to either their established habits or to the products they use following screening.

Number of gingival bleeding sites were measured during BI assessment. BI assesses the severity and number of bleeding points elicited on probing as a measure of gingival condition. To perform the assessment, a probe was inserted approximately 1 mm into the gingival sulcus (at approximately 60 degrees) and moved around the tooth, from the distal interproximal area to the mesial interproximal area, gently stretching the gingival epithelium. Sites which showed signs of bleeding immediately on probing or within 30 seconds of probing were classified as a bleeding sites.

The MGI focuses on the visual symptoms of gingivitis (redness, texture, edema). The MGI was assessed for the facial and lingual/palatal gingiva of all evaluable teeth, four sites per tooth (facial surface - papilla and margin; lingual/palatal surface - papilla and margin). The MGI scoring included 5-point scale ranged from 0 to 4, where 0=Absence of inflammation, 1=Mild inflammation: slight change in color, little change in texture of any portion of the marginal or papillary gingival unit, 2=Mild inflammation: criteria as (1) but involving the entire marginal or papillary gingival unit, 3=Moderate inflammation: glazing, redness, edema, and/or hypertrophy of the marginal or papillary gingival unit, 4=Severe inflammation: marked redness, edema and/or hypertrophy of the marginal or papillary gingival unit, spontaneous bleeding, congestion, or ulceration. Higher score indicates worst outcome.

Supra-gingival plaque was assessed on the facial and lingual/palatal surfaces of all scorable teeth, six sites per tooth using TPI which indicated plaque accumulation in the gingival area of the tooth. Each tooth surface was divided into 3 areas; three scores were recorded facially (mesiofacial, facial, distofacial) and three scores lingually (mesiolin-gual, lingual and distolingual) generating a total of six scores per tooth. The plaque was disclosed and scored on a 6-point scale ranged from 0 to 5 where: 0=No plaque, 1=Separate flecks of plaque at the cervical margin, 2=Thin continuous band of plaque (up to 1 mm) at the cervical margin, 3=Band of plaque wider than 1 mm but covering less than (\<) 1/3 of the tooth surface, 4=Plaque covering greater than or equal to (\>=) 1/3 but \< 2/3 of the tooth surface, 5=Plaque covering \>= 2/3 of the tooth surface.

The cleanliness of the partial denture was evaluated based on the modification of the Clinical Categorization of Denture Cleanliness Index. A suitable dental probe was used to gently scrape the surfaces of the RPD and the PDCI was scored. All surfaces of the RPD were assessed and the highest score applicable was recorded. PDCI scoring system included 5-point scale ranged from 0 to 4, where 0=No visible plaque; no matter adherent to the dental probe on light scraping, 1=No visible plaque; matter adherent to the dental probe on light scraping, 2=Deposits of plaque just visible on careful examination without need to confirm by scraping, 3=Deposits of plaque clearly visible, 4=Gross plaque deposits ("velvet appearance"). Higher score indicates worst outcome.

The extent of calculus on each tooth surface (buccal and lingual) was determined by visual examination. Only definite deposits of hard calculus were recorded. The CI was assessed on the facial and lingual surfaces of each scorable tooth. The CI for each participant was calculated as the mean score of all tooth surfaces (facial/lingual). CI scoring included 4-point scale ranged from 0 to 3 where: 0=No calculus present, 1=Supragingival calculus covering not greater than (\>) 1/3 of exposed tooth surface, 2=Supragingival calculus covering \> 1/3 but not \> 2/3 of exposed tooth surface or presence of individual flecks of Subgingival calculus around cervical portion of tooth or both, 3= supragingival calculus covering \> 2/3 of exposed tooth surface or a continuous band of Subgingival calculus around cervical portion of tooth or both.

The extent of oral debris (defined as soft foreign matter on the surface of teeth) on each tooth surface was determined by running the side of a number 5 explorer (Shephard's crook) probe along the buccal, labial and lingual surfaces and noting the occlusal or incisal extent of the debris as it was removed from the tooth surface. The ODI was assessed on the facial and lingual surfaces of each scorable tooth. The ODI for each participant was calculated as the mean score of all tooth surfaces (facial/lingual).ODI scoring system included 4-point scale ranged from 0 to 3 where: 0=No debris or stain present, 1=Soft debris covering not \> 1/3 of the tooth surface the presence of extrinsic stains without other debris regardless of surface area covered, 2= Soft debris covering more than one third, but not more than two thirds, of the exposed tooth surface, 3=Soft debris covering more than two thirds of the exposed tooth surface. Higher score indicates worst outcome.
