Propolis Lozenges Extract and Their Effect on Salivary Biomarkers and on Oral Health Condition in (19_24) Years Old

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.

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.
