SECONDARY outcome

Timeframe: Baseline

Using the Gingival index by Loe and Sillness 1963, the inflammatory state of the Buccal, Lingual, Mesial and Distal Surfaces of the gingiva will be scored using the following score system: 0= normal gingival without signs of inflammation, no inflammation, no bleeding 1. minor inflammation , slight discoloration, minor surface alterations, no bleeding 2. moderate inflammation, redness, swelling, bleeding upon probing and under pressure 3. strong inflammation, strong redness and swelling, tendency toward spontaneous bleeding, ulcerations After a score is given to each site the scores are summed together and divided by 4 to reach an overall score.

SECONDARY outcome

Timeframe: Baseline

Depth will be measured by a calibrated periodontal probe at 6 different locations, Mesiobuccal, Mid Buccal, Distobuccal, Disto Lingual, Mid Lingual and Mesio Lingual. The longitudinal course will be characterized with respect to the categorical outcome, presence of any bleeding on probing, with initial emphasis being placed upon transition approaches, with specific attention given to shifts from clinically unacceptable to clinically acceptable designations. probing depth is considered variable from one person to the other however a decrease or a shallower probing depth overtime is gererally seen as an improvement , thus any decrease in probing depth would be seen as signs of healing.

SECONDARY outcome

Timeframe: 1 week

Depth will be measured by a calibrated periodontal probe at 6 different locations, Mesiobuccal, Mid Buccal, Distobuccal, Disto Lingual, Mid Lingual and Mesio Lingual. The longitudinal course will be characterized with respect to the categorical outcome, presence of any bleeding on probing, with initial emphasis being placed upon transition approaches, with specific attention given to shifts from clinically unacceptable to clinically acceptable designations. probing depth is considered variable from one person to the other however a decrease or a shallower probing depth overtime is gererally seen as an improvement , thus any decrease in probing depth would be seen as signs of healing.

Measure
Simvastatin Group ( Treatment )
n=24 Participants
Will receive 0.1 ml prepared Simvastatin in 1.2% (W/V) Lecithin/isopropyl palmitate solution (Lipoil®), Poloxamer 407 gel (Polox Gel 20%®) applied topically into the peri-implant gingival sulcus using a plastic syringe with a blunt cannula. Simvastatin: One topical application in peri-implant gingival crevice
