The literature describes that the buccal bone plate has on average less than 1 mm thickness and that the bone remodeling that occurs after the exodontia will alter the vestibular gingival margin independent of the installation of an immediate implant [8, 9].

To achieve laser analgaesia, the laser was positioned at a distance of 2mm from the tooth surface on the gingival margin and slowly moved for 2 min duration using 60 mJ energy and 20 Hz frequency power (low energy, high frequency).

Different restorative techniques have been tried to improve bonding and arrest microleakage in deep proximal cavities filled with composites.6-8 Most of these studies have shown conflicting results and no standard protocol has been established that could be followed to have durable composite restoration in cases where gingival margin extends to cementum.

EVALUATION OF MICRLEAKAGE OF NANO-COMPOSITES USING THREE DIFFERENT RESTORATIVE TECHNIQUES

When the fracture line extends below the gingival margin, there is a high chance of microleakage from the gingival crevicular fluid and difficulty in isolation for postendodontic restorations.
