Intentional Replantation Techniques: A Critical Review

Introduction

Techniques and armamentarium for intentional replantation have varied throughout the years with no universally accepted clinical treatment guidelines. A wide range of success rates has been reported, and accordingly, this treatment method has often been regarded as a treatment of last resort. However, recent studies have shown more consistent success rates as high as 88% to 95%. In light of these new studies, intentional replantation may now be considered a more commonly accepted treatment modality. The purpose of this review was to critically examine reported techniques for intentional replantation.

Diagnostic Accuracy of 5 Dental Pulp Tests: A Systematic Review and Meta-analysis

Introduction

The aim of this systematic review was to investigate and compare the diagnostic accuracy including sensitivity, specificity, adjusted accuracy, adjusted positive predictive value (PPV), and adjusted negative predictive value (NPV) of cold pulp testing (CPT), heat pulp testing (HPT), electric pulp testing (EPT), laser Doppler flowmetry (LDF), and pulse oximetry (PO).

Tooth Discoloration Induced by Different Calcium Silicate–based Cements: A Systematic Review of In Vitro Studies

Introduction

On the basis of many clinical observations, some calcium silicate–based cements have a high potential for staining tooth tissue. This feature greatly limits the use of those cements, particularly for anterior teeth. This review aimed to provide a systematic evaluation of published in vitro studies to determine the effect of different calcium silicate–based cements on dental tissue discoloration.

In Vivo and In Vitro Comparison of Internal and Marginal Fit of Digital and Conventional Impressions for Full-Coverage Fixed Restorations: A Systematic Review and Meta-analysis

PurposeThis study aims to evaluate digital and conventional impressions for full-coverage restorations in terms of marginal and internal discrepancies.Study selectionThe analysis included in vivo and in vitro studies reporting the marginal or internal gap of full-coverage restorations that provide both the conventional and digital impression. The PubMed, Cochrane Trials, and Scopus databases were searched. The quality of clinical trials was rated using Cochrane Collaboration's tool, and the quality of the evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation tool. Heterogeneity among the studies was evaluated, and a meta-analysis with subgroup analysis was conducted whenever it was possible.ResultsThirty-three articles (8 prospective clinical trials and 26 in vitro studies) were selected to extract data after applying the predefined selection criteria. The standard mean difference (SMD) of the meta-analysis for marginal adaptation was ?0.76 (95% confidence interval: ?1.23 to ?0.29) and ?0.59 (95% confidence interval: ?0.93 to ?0.24) for in vitro and in vivo studies, respectively, indicating digital impressions provided significantly less marginal gap than conventional impressions in in vitro studies (P = .002). The impression technique did not significantly influence the internal adaptation.ConclusionsDifferences in marginal adaptation between the digital and conventional groups are not significant for in vivo studies, but for in vitro studies, the digital impression resulted in better marginal adaptation. Based on the Grading of Recommendations, Assessment, Development, and Evaluation approach for marginal adaptation, clinical studies were classified as high confidence and in vitro studies were graded moderate because of the inconsistency. Furthermore, high-quality studies are needed to confirm our results (the International Prospective Register of Systematic Reviews; CRD42017077925).     

Efficacy of 4 % Articaine and 2 % Lidocaine: A clinical study

Objectives

This study was undertaken to compare the anesthetic properties of 4 % Articaine hydrochloride and 2 % Lidocaine both with 1:100,000 epinephrine for mandibular inferior alveolar nerve anesthesia.

Materials and Methods

Thirty healthy patients were included in this randomized double-blind clinical cross over study. Each subject received each test solution at different times. Inferior alveolar nerve block anesthesia was used for extraction of bilateral impacted mandibular third molar on different occassions. The time of onset of action, duration of anesthesia, efficacy of anesthesia, hemodynamic parameters and oxygen saturation were monitored during the procedure. A visual analog scale was used to assess pain during surgery, and thus subjectively evaluate the anesthetic efficacy of the two solutions.

Results

No statistically significant differences were seen in the onset and duration of anesthesia between the Articaine and Lidocaine solutions.

Conclusions

4 % Articaine offers better clinical performance than 2 % Lidocaine, particularly in terms of latency and duration of the anesthetic effect. However, no statistically significant differences in anesthetic efficacy were recorded between the two solutions.     

“Vanishing Bone Disease” in Maxillofacial Region: A Review and Our Experience

Vanishing bone disease (VBD) is a rare disease of unknown etiology which is characterised by progressive replacement of bony framework by proliferation of endothelial lined lymphatic vessels. It has been given numerous names like massive osteolysis, Gorham’s disease, phantom bone disease, and progressive osteolysis. It has no age, sex or race predilection. It may involve single or multiple bones and spread of the disease does not respect the relevant joint as boundary. The first report of the disease was published around two decades back but the mysterious nature of its etiology and ideal management strategy has still not been completely unfolded. The disease may functionally or aesthetically effect the patient and also has the potential to be life threatening. The first case of VBD in maxillofacial region was reported by Romer in 1924, Handbuch der speziellen pathologischen Anatomie and histology, Springer, Berlin. Since then, there have been few case reports of the same in maxillofacial region. We present a review of cases of VBD in maxillofacial region reported in literature along with our experience of a case.     

Chondromalacia as pathological finding in arthroscopy of the temporomandibular joint: A retrospective study

Objective

The objective of this study was to describe the arthroscopic findings of chondromalacia and its relation with the internal derangement of the temporomandibular joint (TMJ).

Reconstruction of Ala of Nose with Bilobed Flap: A 2 Year Follow-up

Basal cell carcinoma accounts for 70–80% of all cutaneous malignancies in the head, face and neck region [2]. This article reports a case of basal cell carcinoma involving the ala of the nose with the excision of the lesion and reconstruction.     

Open treatment of condylar fractures via extraoral approaches: A review of complications

Background

There is considerable controversy about whether condylar fractures should be treated open or closed. Even when there is a clear indication for open treatment, the appropriate approach opens another debate.
