Alternate irrigation with 1 mL antibiotic-containing solution followed by 4 mL 2.5% sodium hypochlorite solution between each size instrument and the consequent one. The antibiotic-containing solution will be prepared by mixing equal quantities of 1.2 gm Co-amoxiclav solution and 600 mg Clindamycin solution at a ratio of 1:1 by volume.

Irrigation with 5 mL MTAD irrigating solution for 5 minutes between each size instrument and the consequent one.

Region of Enrollment

A measure of the plaque levels on the desired tooth surface. The following scores were used:
0 no plaque/debris on inspection and probing
thin film of plaque only visible after probing
ribbon-like layer of plaque covering the sulcus & gingival crown areas but not filling interdental space
thick layer of plaque already visible at inspection and filling interdental space

Plaque Index

An evaluation of the gingival architecture . The following scores were used :
0 Physiologic gingiva
Mild inflammation (slight color change and little change in texture)
Moderate inflammation (moderate glazing, redness, edema and hypertrophy, bleeding on probing)
Severe inflammation (marked redness and hypertrophy, ulceration. tendency to bleed spontaneously)

Gingival Index

An evaluation of the amount of inflammation.
The following scores were used:
0 no bleeding
singular bleeding point
several bleeding points or a thin bleeding line along the marginal gingiva
bleeding in the entire interdental gingival triangle immediately after probing
profuse bleeding during probing, bleeding extending over the marginal gingiva eventually with development of blood drops

Bleeding Index

To calculate the bacterial counts from the diluted plates back to baseline undiluted values, the measurement obtained from the diluted plate was multiplied by 10n (n = number of the serial dilution).

S.Mutans Count

Root resorption was analyzed by comparing the root length before (T0) treatment and after 18 months of treatment( T2). Therefore the data values indicate the difference in the root length ( in mm).

Amount of Root Resorption Observed for Maxillary Lateral Incisor = Length of Root at T0-Length of Root at T2 (in mm)
