Cleaning Ability of Single-File Preparation Technique in Curved Canals

.

Aim: The aim of this study was to compare the cleaning ability of a singlefile system (OneShape) versus multi-file systems (ProTaper Universal & ProTaper Next) in curved root canals. Materials and methods: Sixty mesiobuccal roots from extracted mandibular molars were divided into threegroups (n = 20): PTU, prepared by ProTaper Universal system; PTN, prepared by ProTaper Next system; and OS, prepared by One Shape system. Teeth were longitudinally split into two halves for evaluation by stereomicroscope. Digitised images were analysed using ImageJ Software for the amount of debrisalong the canal walls. Results: No significant difference was found between the three groups in the coronal third of the canals (P = 0.17). However, the One Shape group recorded a significantly higher percentage of debris in the middle andapical thirds (P = 0.003 and P = 0.023, respectively) Conclusions: The single-file system showed relatively decreased cleaning ability in curved canals when compared to the use of rotary full-sequence NiTi systems.

Cemented Single Crown Retention on Dental Implants: An In Vitro Study

.

Purpose:The aim of this study was to determine the influence of selected cements,abutment heights, and aging on the retention of zirconia crowns on zirconiaabutments. Materials and Methods: Zirconia crowns and abutments(height: 4.0 or 5.5 mm) were sandblasted and retained using five differentcements. Axial pull-off tests were performed after thermocycling or 3 days ofwater storage. Results: An increase in abutment height wasassociated with an increase in decementation force when permanent cementationwas tested. The aging protocol showed that temporarily cemented crowns showed asignificant retention decrease, while use of a permanent cement led to amoderate increase. Conclusion: Only use of permanent cementsensures clinically adequate decementation forces.

Are “Human Factors” the Primary Cause of Complications in the Field of Implant Dentistry?

Are “Human Factors” the Primary Cause of Complications in the Field of Implant Dentistry?

.

Complications in medicine and dentistry are usuallyanalyzed from a purely technical point of view. Rarely is the role of humanbehavior or judgment considered as a reason for adverse outcomes. When the roleof human factors is considered, these are usually described in general termsrather than specifically identifying the factors responsible for an adverseevent. The impact of cognitive and behavioral factors in the explanation ofadverse events has been studied in other high-stakes areas such as aviation andnuclear power. Specific protocols have been developed to reduce rates of humanerror, and, where human error is unavoidable, to lessen its impact. Thisapproach has dramatically reduced the incidence of accidents in these fields.This article aims to review how a similar approach may prove valuable in thereduction of complications in implant dentistry.
