The remaining 40% had a dentine matrix staining intensity of + that was also observed in the apical region for both tooth types.
Finally, under the guidance of a dental operating microscope (Carl Zeiss Surgical GmbH, S100), the apical region was filled using the EndoSequence (BC RRM-Fast Set Putty, Brasseler, USA) material up to 4 mm thickness to create an apical seal (Figure 3).
(6) Upon reaching the apical region, the pathogens stimulate inflammatory and immunological responses in the periapical tissues, giving rise to apical periodontitis.
Because perforation repair, root-end induction and root-end filling are essentially forms of partial canal obturation, the orthograde filling of the apical region or the entire root canal system with MTA is the next logical progression in the evolutionary application of this material.
Internal sac with hinge sclerites longer than width of median lobe at apex, curved and expanded at the apex as inverted golf cleat; apical region with dense short spicules; subapical region with sparse short spicules and 2 large dense groups of long spicules; submedian region with sparse short spicules; laterobasal lobes with four groups of large spicules and sparse short spicules; basal region with dense short spicules (Fig.
It consisted of combined lateral compaction in the apical region with vertical compaction of the pulp chamber using a System B device (Elements Obtu- ration Unit from Sybron Endo) with AH-Plus sealer (Dentsply.
Anal valve somewhat as long as forceps, broad basally, sub-triangular in profile, anterior margin almost straight, lateral lobes bent inwards, upper surface armed with minute points and the apical region and lateral lobes with simple setae, marginal setae somewhat.
Chest X-ray showed a mass in the left apical region of the lung.
In this study it became evident that some Zinophora species have a thumb on the apical region of the telopodite which is formed into a single finger-like projection (Zinophora munda group, 9 species), whereas some species have a single saucer-shaped laminate plate with a dentate margin (Zinophora gracilis group, 9 species), while in others it is represented by two processes which are a combination of the aforementioned character states.
Bellen's research team have discovered that the Arp2/3 complex and its activator WASp (Wiskott-Aldrich syndrome protein) function in these daughter cells to transport Delta vesicles to the apical region of the daughter cells.
