Materials used for root conditioning include
FIBRONECTIN
TETACYCLINE
CITRIC ACID
Of these most widely used is citric acid
CItric acid have the following actions
Accelerated healing and new cementum formation after surgical detachment of gingival tissues and demineralisation of root surface by means of citric acid
It has no effect on non planed roots however when applied on planed roots, it leads to producing a 4micromm deep demineralised zone with exposed collagen
Removes debris as also smear layer and makes the exposed dentinal tubules appear wider and funnel shaped orifices
Eliminates bacteria and endotoxins from the root surface
Early fibrin linkage to collagen fibres exposed by the citric acid prevents epithelium migration over treated roots
REcommended technique is as follows::
Raise mucoperiosteal flap
Thoroughly plane the root surface
Apply cotton pledgets soaked in saturated citric acid pH 1 for 2-5 mins
Remove pledgets and irrigate thoroughly
REplace flap and suture
