Primary Outcome Measures
NameTimeMethod
Microbiological assessment of Porphyromonas gingivalisup to 6 months

Subgingival plaque biofilm will be collected using paper cone after making a good isolation of the operated field and put into a sterile microcentrifuge tube containing phosphate buffered saline to be transferred immediately to the Microbiology laboratory for analysis of microbiome. Microcentrifuge tubes will be vortexed for 5 minutes then 200 ul of the resulting suspension will be subjected to DNA extraction using QIAamp DNA minikit. Specific PCR primers targeting gingival plaque associated oral microbiota (Porphyromonas gingivalis) will be used in SYBR Green Real-Time PCR. Amplification of 16SrRNA gene will be used as the denominator against which the amplification of other bacteria will be estimated. The bacterial relative quantification will be calculated automatically by the Rotor-Gene software and expressed as relative fold difference.

Microbiological assessment of Fusobacterium nucleatumup to 6 months

Subgingival plaque biofilm will be collected using paper cone after making a good isolation of the operated field and put into a sterile microcentrifuge tube containing phosphate buffered saline to be transferred immediately to the Microbiology laboratory for analysis of microbiome. Microcentrifuge tubes will be vortexed for 5 minutes then 200 ul of the resulting suspension will be subjected to DNA extraction using QIAamp DNA minikit. Specific PCR primers targeting gingival plaque associated oral microbiota (Fusobacterium nucleatum) will be used in SYBR Green Real-Time PCR. Amplification of 16SrRNA gene will be used as the denominator against which the amplification of other bacteria will be estimated. The bacterial relative quantification will be calculated automatically by the Rotor-Gene software and expressed as relative fold difference.

Microbiological assessment of Tannerella forsythiaup to 6 months

Subgingival plaque biofilm will be collected using paper cone after making a good isolation of the operated field and put into a sterile microcentrifuge tube containing phosphate buffered saline to be transferred immediately to the Microbiology laboratory for analysis of microbiome. Microcentrifuge tubes will be vortexed for 5 minutes then 200 ul of the resulting suspension will be subjected to DNA extraction using QIAamp DNA minikit. Specific PCR primers targeting gingival plaque associated oral microbiota (Tannerella forsythia) will be used in SYBR Green Real-Time PCR. Amplification of 16SrRNA gene will be used as the denominator against which the amplification of other bacteria will be estimated. The bacterial relative quantification will be calculated automatically by the Rotor-Gene software and expressed as relative fold difference.

Secondary Outcome Measures
NameTimeMethod
Probing depthup to 6 months

This is measured from the margin of the gingiva to the base of the pocket using a Williams probe. The normal probing sulcus depth is considered to range from 1 to 3 mm in healthy gingiva.

Clinical attachment lossup to 6 months

This is assessed using a Williams probe from a fixed reference point on the crown to the base of the pocket. Pocket severity is classified by the extent of clinical attachment loss in millimeters (0= normal, 1 or 2 mm = slight, 3 or 4 mm = moderate, ≥ 5 mm = severe).

Plaque indexup to 6 months

This is used to assess the amount of plaque accumulation. Each tooth is examined and scored (0-3), where 0= no plaque, 1= a thin plaque film at the free gingival margin (only seen by running a probe in the sulcus, 2= moderate plaque accumulation, 3= abundance of plaque

Gingival indexup to 6 months

This is used to assess the degree of gingival inflammation. Each tooth is examined and scored (0-3), where 0 = normal gingiva; 1 = mild inflammation: slight change in color, slight edema, no bleeding on probing; 2 = moderate inflammation: redness, edema, and glazing, or bleeding on probing; 3 = severe inflammation: marked redness and edema, tendency toward spontaneous bleeding and ulceration
