What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
clinical attachment loss (CAL)
Time Frame: Day 0 - month 3- month 6
  • All clinical outcomes will be measured baseline, 6 weeks after SRP alone and in conjunction with Omega- 3 and Vitamin D.
  • CAL will be measured form cemento- enamel junction (CEJ) to the depth of the pocket using UNC periodontal probe.
  • It will be recorded at 6 sites per tooth, the recorded readings will be used to generate mean values at each time point.
Day 0 - month 3- month 6

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Plaque index (PI)
Time Frame: Day 0 - month 3- month 6
• through the Silness & Loe plaque index score: score the thickness of plaque, sum the scores, and divide by the number of surfaces/teeth to get an average score. 0: no plaque - 1: thin film on gingival margin - 2: visible plaque in pocket and on gingival margin - 3: dense plaque in pocket and on gingival margin
Day 0 - month 3- month 6
Gingival index (GI)
Time Frame: Day 0- month 3- month 6
through the modified Loe & Silness score by assigning a score to each site based on these criteria as follows. 0: normal gingiva - 2: mild inflammation (slight color change, slight edema, no bleeding on probing) - 3: moderate inflammation (redness-edema-glazing-bleeding on probing) - 3: severe inflammation (marked redness, edema, spontaneous bleeding, or ulceration).
Day 0- month 3- month 6
