The brains were cut coronally
into 40-[micro]m thick sections with a freezing microtome and stained with cresyl violet.
After the brain was completely taken out of the skull, it was incised coronally
at an angle of approximately 60[degrees] at the inferior colliculus-superior colliculus level.
Evaluation of time required for recontamination of coronally
sealed canals medicated with calcium hydroxide and chlorhexidine.
Some studies have reported no increase in post-operative complications after single-visit treatment.2-4 Complications may occur as a result of errors in technique, apical extrusion of debris or failing to seal the canal, both apically and coronally
.7 Since the single-visit root canal treatment is aimed at following an immaculate technique and the canals are sealed in both apicocoronal regions, the chances of flare-up are reduced.11 Single-visit and multiple-visit treatments have their merits and demerits, but the decision depends upon specific selection criterion.
Brain-tissue samples were obtained, embedded in paraffin, and cut coronally
into sections 6 [micro]m thick.
PTR has showed the maximum amount of gutta-percha and sealer removal because of its specific convex flute design, D1 having a cutting tip which causes effective penetration into the root filling material in the coronal third, its tendency to pull the root filling material into its flutes and push it coronally
advanced flap (CAF) is a predictable surgical procedure when there is adequate keratinized tissue present apical to the recession defect in the treatment of Miller Class I and II gingival recessions. CAF alone gives an unstable result for long-term period, despite of having many advantages.
Radiographic investigations revealed that tooth 31 was foreshortened coronally
and had large periapical radiolucency with loss of lamina dura in the apical third of the root.
All canals were instrumented to the working length till a size #35 apically and a size #70 coronally
. The working length was determined by an apex locator (Root ZX; Morita, Tokyo, Japan) and confirmed by a periapical radiograph.
Treatment of gingival recession with coronally
advanced flap procedures: a systematic review.
Comparative evaluation of the effectiveness of coronally
positioned flap with or without acellular dermal matrix allograft in the treatment of multiple marginal gingival recession defects.
Classically, coins are oriented coronally
