Lastly, the higher bond strength of the AH Plus relative to Pulp Canal
Sealer EWT was reported at all levels (apical, middle, and coronal).
Prevalence of pulp canal
obliteration after TDI varies widely in clinical literature, ranging from 3 7% to 40% (Table 1) (4,6,18,25,26,33,37,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58) This range can be explained by differences in sample compositions.
The MIC value of the endodontic toothpastes and their individual components was determined as the lowest concentration capable of completely inhibiting the development of previously established colonies of microorganism that commonly infect the dental pulp canal
. The data obtained were analysed by One-Way ANOVA and Tukey's (P [less than or equal to] 0.05).
Long-term sealing ability of Pulp Canal
Sealer, AH-Plus, GuttaFlow and Epiphany.
These vascular canals are rather thin if compared with basal and pulp canals
, but with almost equal cross section; intersections of the canals form lacunae-like widenings (Fig.
The pulp canal
opening is situated in the posterior corner of the base.
MTA has been successfully used to repair communication between the pulp canal
space and the periodontal tissue.
These changes in injured teeth can include fragment detachment, discoloration, radiographic apical radiolucency, root resorption, and pulp canal
obliteration [6, 8].
Along with diagnosis, treatment planning and clinical expertise, knowledge of the typical pulp canal
system and its frequent variations is a basic requirement for clinical success in root canal therapy.
This is a common sequel to dental trauma and it was referred as Calcific Metamorphosis (CM) also called Pulp Canal
Obliteration (Malhotra & Mala; Oginni et al., 2009).
(2) Following egress from the necrotic pulp canal
system, micro organisms and their by products present in the periradicular area might perforate the cortical plate with the infection draining onto the mucosal or cutaneous surface following the path of least resistance.
obliteration was not regarded as a failure.
