Esthetic Rehabilitation with No-Preparation Veneers Applying BOPT: A Case Report with a 12-Month Follow-Up.

A 45-year-old female patient was referred to the Department of Cosmetic Dentistry, Damascus University, seeking to improve dental aesthetics. The clinical examination showed a low smile line and microdontia in the maxillary arch. The treatment plan consisted of applying no-prep veneers with gingival modification, which is described in the biologically oriented preparation technique (BOPT) as a gingitage technique.

Evaluating the efficiency of two different over-the-counter tooth whitening systems: a randomised controlled clinical trial.

Objectives: To compare whitening efficiency and tooth sensitivity (TS) of two different over the counter (OTC) whitening systems in comparison to conventional at-home bleaching using 20% carbamide peroxide.

Materials And Methods: A randomised controlled clinical trial was conducted with three parallel groups (n = 13): (A) at-home whitening using 20% carbamide peroxide (20% CP), (B) OTC ready-to-use gel trays and (C) OTC-paint on gel. Clinical colour change values (ΔE) were measured using spectrophotometry at T0: baseline, T1: 7-day and T2: 14-day from whitening start, T3: 2 weeks and T4: 6 months after whitening end.

Scaffolding Self-Regulated Learning in Operative Dentistry Through Self-Assessment Training.

Objectives: This study aimed to investigate how effective self-assessment training is in improving the self-regulated learning (SRL) ability of operative dentistry students. The secondary aim was to explore students' attitudes towards self-assessment in clinical settings.

Introduction: Self-assessment has been the focus of dental education research for decades and has been claimed to be cornerstone in the SRL process.

Evaluation of a workplace assessment method designed to improve self-assessment in operative dentistry: a quasi-experiment.

Background: Dental education has placed continued emphasis on self-regulated learning (SRL) and its subprocess, self-assessment. This study set out to evaluate the effectiveness of a novel workplace assessment method in developing trainees' self-assessment of operative procedures.

Methods: A Direct Observation of Procedural Skills (DOPS) form was modified for the use and measurement of self-assessment.

Effect of bioactive glass paste on efficacy and post-operative sensitivity associated with at-home bleaching using 20% carbamide peroxide: a randomized controlled clinical trial.

Background: The aim of this study was to evaluate the effect of bioactive glass (BAG) 45S5 paste on colour change and tooth sensitivity (TS) when used in combination with 20% carbamide peroxide (CP) during at-home vital tooth bleaching.

Methods: Twenty-four patients were selected and assigned into two experimental groups (n = 12) in a double-blind study design. Each patient received 20% CP followed by the application of either BAG paste or non-active placebo paste.

Peer-assessment ability of trainees in clinical restorative dentistry: can it be fostered?

Objectives: The study was conducted to investigate whether peer-assessment among dental students at the clinical stage can be fostered and become closer to that of experienced faculty assessors.

Methods: A prospective pilot study was conducted in 2021 at the Faculty of Dentistry, Damascus University. Sixteen 5th year clinical students volunteered to participate in the study.

Bridging the gap between self-assessment and faculty assessment of clinical performance in restorative dentistry: A prospective pilot study.

Purpose/objectives: The current study was undertaken to investigate whether self-assessment of clinical skills of undergraduate dental students could be bridged with faculty assessment by deliberate training over an extended period. A secondary aim was to explore students' perception of self-assessment and its effect on their learning and motivation. MATERIAL AND METHODS: A prospective pilot study was conducted at the Department of Restorative Dentistry at Damascus University.

Management of a Rare Case of Geminated and Fused Central Incisors in the Same Maxillary Dental Arch.

A 27-year-old man presented with developmental disorders in the maxillary incisors and asymmetric smile. Differential diagnosis between geminated and fused maxillary central incisors was conducted using cone-beam computed tomography (CBCT). The complexities of root canal system was handled using suitable shaping instruments and ultrasonic activation tips.

Effect of Er:YAG laser-activated irrigation on dentine debris removal from different parts of the root canal system: An in vitro study.

Background: There is insufficient information available in the literature about the efficacy of laser-activated irrigation (LAI) in removing dentine debris at different coronal-apical levels of the root canal system (RCS).

Objectives: To evaluate the efficacy of erbium (LAI) in removing dentine debris from different coronal-apical levels of the RCS when compared to passive ultrasonic irrigation (PUI) and conventional irrigation (CI).

Material And Methods: Forty-five single-rooted human teeth were split longitudinally into halves.

Effect of CPP-ACP on efficacy and postoperative sensitivity associated with at-home vital tooth bleaching using 20% carbamide peroxide.

Objectives: To evaluate CPP-ACP effect on colour change and tooth sensitivity (TS) associated with at-home vital tooth bleaching using 20% carbamide peroxide (CP).

Methods: A randomised double-blind placebo-controlled clinical trial was conducted to measure the TS and tooth colour change of 24 patients at 3-day, 7-day, 14-day and 30-day periods. The participants were instructed to apply 20% CP (7 days-04 h each) followed by the application of either CPP-ACP or non-active placebo paste, delivered by the bleaching custom tray (7 days-30 min each).

Evaluating the Clinical Use of Light-emitting Diode vs Halogen Photocuring Units.

Purpose: To clinically examine the effect of the type of ight-curing unit on the light intensity output and to assess different operator variables which affect light curing of photo-initiated restorative dental materials, in Damascus, Syria.

Materials And Methods: A total of 185 private dental practices in the Damascus area were visited to invite the clinicians to participate in this study. The intensity of 163 light-curing units (LCUs) was assessed by radiometry in a standard protocol.

Surface pre-conditioning with bioactive glass air-abrasion can enhance enamel white spot lesion remineralization.

Objective: To evaluate the effect of pre-conditioning enamel white spot lesion (WSL) surfaces using bioactive glass (BAG) air-abrasion prior to remineralization therapy.

Methods: Ninety human enamel samples with artificial WSLs were assigned to three WSL surface pre-conditioning groups (n=30): (a) air-abrasion with BAG-polyacrylic acid (PAA-BAG) powder, (b) acid-etching using 37% phosphoric acid gel (positive control) and (c) unconditioned (negative control). Each group was further divided into three subgroups according to the following remineralization therapy (n=10): (I) BAG paste (36 wt.

Enamel white spot lesions can remineralise using bio-active glass and polyacrylic acid-modified bio-active glass powders.

Objective: To evaluate the potential of bio-active glass (BAG) powder and BAG containing polyacrylic acid (PAA-BAG) to remineralise enamel white spot lesions (WSL).

Methods: 32 human enamel samples with artificial WSLs were assigned to 4 experimental groups (n=8); (a) BAG slurry, (b) PAA-BAG slurry, (c) "standardised" remineralisation solution (positive control) and (d) de-ionised water (negative control). Mechanical properties of enamel were assessed using surface and cross-section Knoop microhardness.
