The Effects of Water and Acetone-based Dentin Adhesives on Apical Microleakage

The Journal of Contemporary Dental Practice, 2004
Abstract In this study, the aim was to assess the in vitro apical microleakage of a resin-based sealer used with two different adhesives. Thirty nine freshly extracted maxillary incisors were used. The teeth were decoronated at the cemento-enamel junction with a water-cooled fissure bur.

Evaluation of apical microleakage of teeth sealed with four different root canal sealers [PDF]

Journal of Applied Oral Science, 2006
OBJECTIVES: to compare the apical sealing ability of four root canal sealers. MATERIAL AND METHODS: forty extracted human maxillary canines were instrumented 1 mm short of the anatomical apex and randomly assigned to four groups (n=10), according to the root canal sealer used for obturation: Endofill, AH Plus, EndoREZ and Epiphany.

EVALUATION OF THE APICAL SEAL AFTER POST SPACE PREPARATION: IN VITRO STUDY [PDF]

Journal of IMAB, 2019
Introduction: Large crown destruction often leads to restoring endodontically treated teeth using post and core. As a result of post space preparation, the integrity of the apical seal can be affected, thus increasing the chances of microleakage ...

Changes in the Location of the Second Mesiobuccal Canal Orifice After Canal Preparation in Maxillary First Molars

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated angular and linear positional changes of the second mesiobuccal (MB2) canal orifice in maxillary first molars and proposed a guideline for its localization. Twenty‐eight extracted maxillary first molars with four canals were analysed. After access cavity preparation, all canals except MB2 were instrumented. The initial and

Comparative Evaluation of Apical Microleakage of Retrograde Cavities Filled with Glass Ionomer Cement, Light-cured Composite, Mineral Trioxide Aggregate and Biodentine [PDF]

Journal of Clinical and Diagnostic Research, 2019
Introduction: It is clinically very important to improve the seal between the root canal and the periapical tissues. Retrograde filling materials with good sealing properties increase the success rates of periapical surgery predictably.

Multicenter RCT 6‐Year Survival of Zirconia‐Reinforced Lithium Silicate Endocrowns: 90° Shoulder Versus Butt‐Joint Margins

International Endodontic Journal, EarlyView.
ABSTRACT Objectives Margin design significantly influences endocrown biomechanical performance. Nevertheless, long‐term clinical data comparing margin designs within a singular zirconia‐reinforced lithium silicate (ZLS) system remain scarce. This study reports the 6‐year follow‐up results of a multicenter, prospective, randomized, assessor‐blinded ...
