Similarly, no statistically significant differences were found between the experimental groups when the percentage of increase in volume at the apical third
As to the thirds, AA rates ranged between 47.0 and 59.3 mg 100 [mL.sup.-1]; 48.0 and 60.2 mg 100 [mL.sup.-1] and between 48.28 and 61.38 mg 100 mL on the basal, intermediate and apical thirds
The results of SEM analysis have shown that all the three sealers have good adhesion to the root canal walls in the apical third
. In the middle and the cervical third, there was good adaptation of the sealer only in the samples obturated with Gutta Flow, while the samples obturated with N2 and Endomethasone show weak adhesion of the sealer and noticeable presence of cracks in-between the sealer and the canal wall.
Most of the debris of gutta-percha and sealer was detected in the apical third
and the least of it in the coronal third in all groups, which confirms the previous studies (16, 17, 31).
These researchers reported smear-free dentine walls in the apical third
of the canals.
In the present study, the measurement of the dentine thickness of the root in cross-sectional plane (Table 6) (Figure 3) showed that the mesial surface had the least dentine thickness of all the four surfaces (in apical third
, maxillary canine ranged between 0.59 mm and 2.09 mm and mandibular canine ranged between 0.54 mm and 1.89 mm).
20) distinctly club-shaped, basally constricted, apically smoothly rounded, on apical third
a few sparse small setulae, apically some more setulae, on inner side on apical third
a dense brush of short setulae, no microtrichia except for small patch near base; surstyli interconnected via slender processus longi; cerci simple, somewhat rectangular, tapering basally, rather broad, proportion length/width 2.2, covered with microtrichia and setulae; phallapodeme rather slender (Fig.
REDESCRIPTION: DORSAL COLORATION: Ground color, including antennal segments I to III, brown to dark brownish orange; antennal segment IV dark reddish brown with apical third
paler; head lateral to tylus, lateral margin of scutellar disk, and apical margin of hemelytra dark reddish brown.
(17) The unfavorable geometry of the canal space (18) and a preponderance of sclerotic radicular dentin in the canal's apical third
(19) prevents a true, gap-free seal as suggested by the monoblock moniker used in many advertisements.
