Introduction: Local anesthetics are most drug often used in dentistry, notably safe drug being considered when administered carefully and within limits therapeutic dosages. Demand to demonstrate possible cardiovascular changes of clinical significance relating to the use of local anesthetics associated to vasoconstrictors are extensive and aims to make sure about the safety of its clinical use. The aim of this study was to evaluate the cardiovascular effects resulting from infiltrative administration 3% mepivacaine hydrochloride (54mg) and 2% me pivacaine hydrochloride (36mg) associated with epinephrine hydrochloride 1: 100,000 (18mg).

Method: Twenty normotensive patients’ volunteers were evaluated during low complexity restorative procedure in upper posterior teeth. During the experiment were monitored the blood pressure and heart rate through the oscillometric and fotopletismográfico method for non-invasive monitor. Mean values were recorded every minute and continuously during the Es of the experiment as follows: Phase 1 - con trol period (10 min.). On Phases 2 and 3 the Es were: (E1) baseline period (10 min.), (E2) preparation period (3 min.), (E3) anesthesia period (2 min.), (E4) anesthesia latency period (5 min ) (E5) restorative period (10 min), (E6) final period (10 min). 

  The purpose of the study was to investigate the treatment outcomes on the abutments with severely advanced periodontitis (SAP) and secondary occlusal trauma (SOT), using the Sandwich’s technique of combined provisional prosthesis (PP), non-surgical periodontal therapy (NSPT) and crown and sleeve- coping telescopic denture (CSCTD). A total of 272 teeth were used as the abutments of 45 CSCTDs, which included PP, NSPT, and CSCTDs. Clinical records revealed that teeth that received PP, NSPT, and CSCTDs had follow-up periods ranging from 5.1to 39 years in maxillary and mandibular teeth, respectively. The periodontal parameters of the abutments included gingival index, plaque index, probing depth, and clinical attachment levels at the baseline and the end of study. Supportive periodontal treatment was made at 2- to 3-month intervals. The average cumulative survival rate of abutments was 93.0%. The distal free end abutment (DFEA) survival rate was 89.1%. Twelve DFEAs that were lost, accounting for a failure rate of 63.2% among a total 19 DFEAs for CSCTD therapy throughout the end of the study. We concluded that the use of Sandwich’s technique in treating SAP with SOT appeared to be an alternative and valuable option.

 Abstract

Background: Different dental procedures have different levels of anxiety, and the tooth extraction is in the top list of most frightening dental procedures. This anxiety should carefully managed physically and psychologically. Although there are several scales available to measure anxiety from dental treatment, a scale for measuring anxiety related to tooth extraction is still absent. The aim of the study was to develop a new scale; the tooth extraction anxiety (TEA) scale; that is specifically measure anxiety in patients undergoing tooth extraction.

Materials and Methods: Two hundred and ninety two patients who presented for simple tooth extraction were recruited from two special ized dental centers in Mosul, Iraq. Each participant completed two self-administrated questionnaires; The Short version of Dental anxiety inventory (s-DAI) and the TEA scale. Moreover, Candidates asked to rate the amount of their anxiety toward tooth extraction on 11- point Numeric Rating Scale (NRS). Results: Cronbach’s α for the present sample was 0.84 and all items of the scale are relevant (Cronbach’s α values if any item deleted ranged between 0.811- 0.846). Correlations with the s-DAI and the NRS were 0.44, P<0.01 and 0.48, P<0.01 respectively. The results indicated that the TEA scale has good reliability and acceptable validity.

Conclusion: This study developed and validated the TEA scale. It is easy to administer in general dental practices

 Objective: Due to the increasing demands of conservative fixed dental prostheses; many dentists have been using resin bonded fixed partial dentures (RBFPDs). Advances in adhesive technology together with a better understanding of the clinical function of such restorations have allowed resin-bonded fixed partial dentures to play an important role in clinical practice. The present in vitro study aimed to determine the effect of basic bridge designs of anterior resin bonded fixed partial dentures and added retentive mean on debonding of metal frameworks with different metal surface treatments.
