| Measure | Description | Time Frame |
|---|---|---|
| Clinical Assessment of Plaque index(PI) | Visual Analog Score for plaque for detection amount of plaque accumulation so assess patient oral hygiene. recording is based on both soft and mineralized debris. Each surface will have a score from 0 to 3. 0: no plaque
| 6 months |
| Clinical Assessment of Gingival index(GI) to assess gingival inflammation. 0: normal gingiva. 1: mild inflammation . 2: moderate inflammation . 3: sever inflammation marked redness and edema and spontaneous bleeding. | Visual Analog Score for gingival inflammation | 6 months |
| Clinical Assessment of Probing depth (PD). | measured by milli meters for detection of level of periodontal destruction. | 6 months |
| Clinical Assessment of Clinical attachment level (CAL) . | measured by milli meters for detection of level of periodontal destruction. | 6 months |
| Clinical Assessment of Gingival recession(GR) | measured by milli meters for detection of level of apical migration of gingival attachment. | 6 months |
| Clinical Assessment of Modified sulcular bleeding index (MSBI) | Visual Analog Score of bleeding for detection of inflammatory status level. Modified Sulcus Bleeding Index(MSBI) 0 = No bleeding on bleeding.
| 6 months |
| Measure | Description | Time Frame |
|---|---|---|
| Microbiological assessment through real time PCR assay for quantification of total bacterial load by universal probe and primer set (16sr RNA) | quantification of total bacterial load | 3 months |
