Study summary

The goal of this clinical trial is to test the efficiency of using lozenges containing propolis extract over one week to control gingival inflammation and plaque accumulation by measuring the clinical periodontal parameters (Gingival index, plaque index) in comparison with a control group given oral hygiene instruction only in patients with biofilm induced gingivitis (moderate gingivitis)

Objectives:

  1. Evaluate the clinical efficiency of using lozenges containing propolis extract over 7 days to control gingival inflammation and plaque accumulation by measuring the clinical periodontal parameters (Gingival index, plaque index) in comparison with a control group given oral hygiene instruction only in patients with biofilm induced gingivitis (moderate gingivitis).
  2. Measuring levels of salivary cytokines, IL-1Beta, and IL-10 by ELISA at Baseline visit before using lozenges containing propolis and after 7 days of using lozenges containing propolis compared to a control group with oral hygiene instruction only.
  3. Investigate and compare the association of salivary interleukins of IL-Beta and IL-10 in periodontal health and generalized gingivitis.
  4. Evaluate the correlation between clinical periodontal parameters and salivary (IL-1Beta and IL-10).
  5. Evaluate subjects' perception of lozenges containing propolis extract and oral hygiene instructions after 7 days.
Read the detailed description

100 subjects will be enrolled, who show generalized gingivitis (moderate gingivitis) with no Periodontal pocket depth>3 mm, intact periodontium, and no loss of periodontal attachment), caused by the accumulation of plaque. 50 subjects are case that given a lozenge containing propolis and oral hygiene instructions, and 50 subjects were control that were given oral hygiene instructions only. The participants will be asked to chew a lozenge twice per day and Discontinuation of the lozenges will be advised in cases of any allergic reaction. in baseline visit at the beginning, Saliva collection for IL-1β and IL-10 measurement, then clinical periodontal parameters examination starting with gingival index (Loe and Silness in 1963) designed to assess the severity and quality of gingival inflammation in an individual or population. The gingival inflammation is assessed on the basis of color, consistency, and bleeding on probing. A periodontal probe will be run along the gingival margin. The gingiva surrounding the tooth is assessed at four sites: mesio-facial papilla, facial marginal gingiva, disto-facial papilla and lingual marginal gingiva. Then finally followed by the Plaque Index (Loe and Silness in 1963). the data had been recorded from labial/buccal and lingual/palatal surfaces.

First visit after 7 days, from the baseline visit. Saliva collection and clinical periodontal parameters scoring (GI, PI) will be performed again as described at the baseline visit.

What researchers measure

Primary outcomes

  1. Changes in the clinical periodontal parameter (Gingival index)

    Subjects will undergo the measurement of the gingival index according to (Loe \& Silness in 1963), designed to assess the severity and quality of gingival inflammation in an individual or population. The gingival inflammation is assessed on the basis of color, consistency, and bleeding on probing. The Gingival Index (GI) scores each site on a 0 to 3 scale Score 0 : Normal gingiva score 1: Mild Inflammation- slight change in color, Slight oedema. No bleeding on probing. score 2: Moderate inflammation-redness, oedema and glazing. Bleeding on probing. score 3: Sever inflammation-marked redness and edema. Ulceration. Tendency to spontaneous bleeding.

    Time frame: (0, 7days)

Secondary outcomes

  1. Changes in the clinical periodontal parameter (Plaque index )

    To determine the patients' plaque index, their dental plaque thickness was evaluated by probing the mesial, distal, buccal, and palatal surfaces of all teeth using a Williams periodontal probe. The individual's plaque index was determined by summing the values obtained for each tooth and calculating the averages.Silness \& Löe (Silness \& Löe,1964) reference values were taken as a basis The Plaque Index (PI) scores each site on a 0 to 3 scale Score 0 : No plaque is in the area adjacent to the gingiva. Score 1: There is a plaque in the form of a thin film on the gingival margin. Score 2: There is a visible plaque in the gingival pocket and gingival margin. Score 3: There is a dense plaque in the gingival pocket and on the gingival margin.

    Time frame: (0, 7days)

  2. Changes in salivary cytokines (IL- 1β , IL-10)

    ELISA kit will analyze salivary interleukins, and concentrations are measured according to manufacturing instructions, were picogram per liter for interleukin 1 beta levels and nanogram per milliliter for interleukin 10 levels 0 day: Saliva collection for IL-1β and IL-10 measurement, then clinical periodontal parameters examination starting with the gingival index finally followed by the Plaque index 7 days: Saliva collection and clinical periodontal parameters scoring (GI, PI) will be performed again as described at the baseline visit,

    Time frame: (0, 7days)
