V arious therapeutic procedures have been designed to promote new attachment and regeneration of periodontal tissues lost in periodontal disease. New attachment may be defined as the formation of a new cementum with inserting extrinsic collagen fibres occurring on a root surface deprived of its periodontal ligament, whether or not this has occurred because of periodontal disease or by mechanica...

Biomaterials have evolved over the past three decades and are relatively specialized, highly biocompatible, but low-strength dental materials. Bioactive materials can interact with living tissues or systems. The newly emerging bioactive category of has expanded clinical uses in restorative dentistry endodontics. Examples Calcium Silicate containing Mineral Trioxide Aggregate (Portland cement); ...

Regenerative periodontal therapy aims at reconstitution of the lost periodontal structures such as new formation of root cementum, periodontal ligament and alveolar bone. Findings from basic research indicate that enamel matrix protein derivative (EMD) has a key role in periodontal wound healing. Histological results from animal and human studies have shown that treatment with EMD promotes peri...

Local periodontal therapy primarily consists of supraand subgingival debridement, and instruction and motivation for the improvement of oral hygiene. Effective regular mechanical plaque control has been proven to be one of the most important measures to avoid and control recurrence of infection (Axelsson and Lindhe, 1978; Axelsson and Lindhe, 1981a; Axelsson and Lindhe, 1981b). In addition resi...

Root resorption (RR) is defined as the loss of dental hard tissues because of clastic activity inside or outside of tooth the root. In the permanent dentition, RR is a pathologic event; if untreated, it might result in the premature loss of the affected tooth. Several hypotheses have been suggested as the mechanisms of root resorption such as absence of the remnants of Hertwig's epithelial root...
