Rationale: Criteria for preparation of the oral cavity is not a standard inclusion in current guidelines hydrogen-methane breath testing. The aim this study was to determine how pre-test mouthwash may impact test Results upon which diagnosis and treatment recommendations are based.

Objectives The main goal of this study was to evaluate the fracture resistance of maxillary second premolar teeth with standard and conservative mesio-occluso-distal (MOD) cavity designs. Methods Sixty maxillary second premolars were randomly divided into 6 Groups of 10 teeth. G1 consisted of intact teeth. G2 was prepared with separated proximal boxes that were designed to be 1 mm approximate...

INTRODUCTION The introduction of piezoelectric instruments in endodontic surgery allowed clinicians to manage the bone tissue with precision reducing the risk of damaging soft tissues. Although such instruments can also be used to prepare root-end cavity, few information is available on the effect of piezosurgery on dentine. This cadaveric study investigated the integrity of root apices after r...

BACKGROUND The objective of this study is to determine if ultrasound-guided trial transfer (UTT) in the office in preparation for an IVF cycle can be utilized as an alternative and/or adjunct to ultrasound-guided embryo transfer (UGET). METHODS Patients planning to undergo an IVF cycle at an academic centre were included. Each patient underwent an UTT in the office by the same practitioner. T...

The aim of this study was to evaluate the Vector system in comparison to the conventional technique in cavity preparation. Four extracted primary teeth with no restorations and similar fissure carious lesions and four permanent teeth extracted for orthodontic reasons were used. Class I preparations were made provided that the caries depth remained within the dentin limits. Two teeth were treate...

BACKGROUND The purpose of this study is to assess predictors of inadequate endometrial cavity thickness (ECT), defined as < 8 mm, in frozen embryo transfer (FET) cycles. METHODS This is a retrospective cross-sectional study at an academic fertility center including 274 women who underwent their first endometrial preparation with estradiol for autologous FET in our center from 2001-2009. Multi...

INTRODUCTION The conventional method of teaching endodontics has some drawbacks. Due to the small size of the oral cavity, students cannot closely observe the clinical procedure. Use of new teaching modalities such as the intraoral camera may obviate this problem. This study assessed the effect of video-assisted clinical instruction in dentistry (VACID) on dental student's knowledge and perform...

We present a scheme for a quantum optical implementation of Grover's algorithm based on resonant atomic interactions with classical fields and dispersive couplings with quantized cavity fields. The proposed scheme depends on preparation of entangled states and is within current state-of-the-art technology.

This study showed a statistically significant difference between the microhardness of reparative and primary dentin at both five-and eight-week intervals. Reparative dentin from occlusal trauma is harder than reparative dentin underlying a cavity preparation at the 99% level. No statistical difference was noted in the hardness of reparative dentin underlying different materials, but trends were...

Formocresol is common treatment in exposed pulp of primary teeth at caries, trauma and damaged with cavity preparation. Although, clinical and radiographic success and good clinical results are observed, dentistry societies are still searching for materials interchangeable with formocresol. Suab1 is a phytochemical agent that was selected because of its anti- bleeding effect. In this study, we ...
