CLASSIFICATION OF ROOT RESORPTION : 

CLASSIFICATION OF ROOT RESORPTION BASED ON THE NATURE PATHOLOGIC -seen in both Deciduous & permanent dentition PHYSIOLOGIC Seen in deciduous dentition

BASED ON ANATOMICAL OCCURRENCE OF REGION : 

BASED ON ANATOMICAL OCCURRENCE OF REGION INTERNAL EXTERNAL - APICAL - LATERAL - CERVICAL

INTERNAL RESORPTION : 

INTERNAL RESORPTION ETIOLOGY - trauma -caries - iatrogenic procedures as restorative procedures, crown cutting procedures - Ca(OH)2 procedures- pulpotomy, pulp capping - orthodontics - bruxism - cracked tooth

CLINICAL FEATURES : 

CLINICAL FEATURES Usually asymptomatic unless it perforates the root Common in max central incisor Spreads rapidly in primary teeth Pathognomic feature is pink spot appearance of tooth which represents the hyperplastic vascular pulp tissue showing off through the crown of the tooth

Radiographic appearance : 

Radiographic appearance Uniform enlargement of the canal Usually bone changes nt evident

MANAGEMENT : 

MANAGEMENT Without perforation- endodontic therapy With perforation a. surgical - surgical flap - root resection - intentional replantation b. Nonsurgical - Ca(OH)2 therapy obturation
