An evaluation of wear of human enamel opposed by ceramics of different surface finishes.

Statement Of Problem: Surface of porcelain restoration is a matter of clinical concern because of its abrasive action on the opposing enamel.

Purpose: This study comparatively evaluated wear of enamel when opposed by three different surface finishes of ceramic.

Materials And Methods: A total of 60 metal-ceramic discs (10 mm × 2 mm) with different surface finishes were fabricated.

Broken instrument retrieval with indirect ultrasonics in a primary molar.

Background: The separation of a file during pulpectomy is a rare incident in primary teeth due to inherently wider and relatively straighter root canals. A broken instrument hinders the clinician from optimal preparation and obturation of the root canal system invariably leading to failure, although in such teeth, an extraction followed by suitable space maintenance is considered as the treatment of choice. This case report demonstrates successful nonsurgical retrieval of a separated H file fragment in 84.

The comparative effects of 0.12% chlorhexidine and herbal oral rinse on dental plaque-induced gingivitis: A randomized clinical trial.

Easy Accurate Transfer of the Sculpted Soft Tissue Contours to the Working Cast: A Clinical Tip.

Tooth replacement in the esthetic zone presents a myriad of challenges for the clinician. An ovate pontic accurately duplicates the emergence profile of the natural tooth it replaces in order to provide an esthetic, yet cleansable prosthesis. The accurate transfer of this sculpted tissue beneath the pontic of the provisional restoration is critical to provide the dental laboratory technician with the necessary information to fabricate a definitive restoration with an appropriate emergence profile.

Zirconia Intra Mucosal Inserts as a Retentive Aid for Maxillary Complete Dentures: A Case Report.

Complete dentures fabricated for edentulous patients with resorbed ridges generally have compromised retention and stability. The use of intramucosal inserts in order to aid retention of a maxillary denture has been reported in the past. Zirconia is a tissue compatible biomaterial whose scope and application in dentistry is on the rise.

Three-Dimensional Evaluation of Alveolar Bone and Soft Tissue Dimensions of Maxillary Central Incisors for Immediate Implant Placement: A Cone-Beam Computed Tomography Assisted Analysis.

Introduction: This study explored the relationship between the thickness of bone and soft tissue along the labial and palatal aspect of maxillary central incisors. The influence of overall socket width, labiopalatal positioning of the incisor on the bone, and soft tissue thickness were also investigated.

Materials And Methods: This study used cone-beam computed tomography of 150 patients to determine labial, palatal soft and hard tissue thickness, labiopalatal (B-P) socket width and corelated the same to the labiopalatal positioning of maxillary central incisors.

Access to abutment screw in cement retained restorations: a clinical tip.

Abutment screw loosening has been reported to be the most common prosthetic complications occurring in screw retained as well as cement retained implant restorations. Different methods to treat this issue have been reported in the literature so far; however these have their own short-comings. Retrievability of an implant restoration intact becomes a clinical challenge when the restoration is cement retained especially with an angulated abutment.

Scanning Electron Microscopic Evaluation of Root Canal Surfaces Prepared with LightSpeed & Endowave Rotary System.

Background And Objectives: The purpose of this in vitro study was to evaluate and compare the cleaning efficiency on root canal surfaces prepared with LightSpeed and Endowave rotary instruments.

Materials And Methods: A total of 30 freshly extracted human mandibular premolars were subjected for the study. They were divided into two groups, each group consisting of 15 teeth.

Staged ridge splitting technique for horizontal expansion in mandible: a case report.

Ridge split procedures are commonly performed for horizontal augmentation of narrow ridges which would otherwise preclude implant placement. A 47-year-old patient with bilaterally edentulous posterior mandibular ridges was treated in the Department of Periodontology and Implantology, M.A.

Evaluation of experimental coating to improve the zirconia-veneering ceramic bond strength.

Purpose: To evaluate the shear bond strength (SBS) between zirconia and veneering ceramic following different surface treatments of zirconia. The efficacy of an experimental zirconia coating to improve the bond strength was also evaluated.

Materials And Methods: Zirconia strips were fabricated and were divided into four groups as per their surface treatment: polished (control), airborne-particle abrasion, laser irradiation, and application of the experimental coating.

Intraorifice sealing ability of different materials in endodontically treated teeth: An in vitro study.

Background: Microbial contamination of the pulp space is one of the major factors associated with endodontic failure. Thus, in addition to a three dimentional apical filling a coronal seal for root canal fillings has been recommended.

Aim: The present study was conducted to evaluate and compare the intra-orifice sealing ability of three experimental materials after obturation of the root canal system.

Prosthodontic management of a completely edentulous patient with microstomia: a case report.

Patients with microstomia who need to wear removable dental prosthesis often face difficulty of being unable to insert or remove the prosthesis because of restricted opening of the oral cavity. Prosthetic rehabilitation of patients with microstomia presents difficulties in all the clinical steps. In such patients, it is difficult to make impressions and fabricate dentures using conventional method.

Salivary pH: A diagnostic biomarker.

Objectives: Saliva contains a variety of host defense factors. It influences calculus formation and periodontal disease. Different studies have been done to find exact correlation of salivary biomarkers with periodontal disease.

The shaping ability was determined by comparing pre- and post-instrumentation CBCT scans and data analysed with SPSS program using the Chi-square test.

Future prospects of systemic host modulatory agents in periodontal therapy.

Periodontitis is an inflammatory disease caused by microbial infection that leads to destruction of supporting tissues of the teeth. The periodontal tissue destruction is a result of both microbial activity as well as host response. The best chance for clinical improvement may come from implementing complementary treatment strategies that target different aspects of the periodontal balance.

Background And Objectives: Research has shown that mechanical methods of periodontal therapy alone may fail to eliminate the tissue-invasive pathogenic flora; therefore, considerable attention has been given to adjunctive antimicrobial measures. The purpose of this study is to evaluate the efficacy of diode laser as an adjunct to mechanical debridement in periodontal flap surgery, on the basis of clinical parameters and microbiological analysis.

Materials And Methods: A total of 30 patients with generalized chronic periodontitis with probing depth >5 mm after phase I therapy were included in the study.

Combined orthodontic and surgical treatment of a severe skeletal Class III malocclusion: a case report.

This report describes a combined orthodontic and surgical treatment approach for a severe skeletal Class III malocclusion in a young Indian woman with serious esthetic concerns. The case required significant surgical correction in the anteroposterior and vertical planes, involving surgeries in both the maxilla and the mandible. The case required the use of mini-implant anchorage in the presurgical phase as well as postorthodontic prosthodontic rehabilitation to replace missing posterior teeth to restore the occlusal table.
