Teeth with necrotic pulp
are so-called infection foci.
Responses of immature permanent teeth with infected necrotic pulp
tissue and apical periodontitis/abscess to revascularization procedures.
It was due to infected root canal system and remnant of the necrotic pulp
induced the colonisation and formation of bacterial biofilm within the complexity of root canal system which in turn the bacterial invasion reached the periapical tissue to cause apical periodontitis.
Treatment was initiated with access cavity preparation in 11 and 21; necrotic pulp
tissue from the root canals was extirpated and canal was irrigated with physiological saline and dried with paper points.
Pre-operative pulp status was checked and found as irreversible pulpitis and necrotic pulp
60% and 40% respectively (Fig 3).
The prevalence of pain in patients with vital pulp was significantly higher than patients with necrotic pulp
(P = 0.
All remnants of restorative materials and necrotic pulp
tissue must be removed completely.
The RCs of primary teeth with necrotic pulp
and chronic interradicular/apical lesions present a high number of bacterial species and often exhibit polymicrobial infection with a high prevalence of anaerobic bacteria.
Common indications for root canal therapy were necrotic pulp
Forty primary maxillary incisor teeth with irreversibly infected or necrotic pulp
tissue and completely formed roots were included in the study.
Following access cavity preparation, necrotic pulp
tissue was removed and the working length estimated.
The infection from the necrotic pulp
in the root canal system formed tough biofilm as the defence and virulence system of mixed flora.
