Direct composite veneers - restoring esthetics by procuring patient demand: a case report

Re-establishing a patient’s lost dental esthetic appearance is one of the most important topics for contemporary dentistry. New treatment materials and methods have been coming on the scene, day by day, in order to achieve such an aim. Most dentists prefer more conservative and aesthetic approaches, such as direct and indirect laminate veneer restorations, instead of full-ceramic crowns for anteriors where aesthetics is really important. Laminate veneers are restorations which are envisioned to correct existing abnormalities, esthetic deficiencies and discolorations. Laminate veneer restorations may be processed in two different ways: direct or indirect. Direct laminate veneers have no need to be prepared in the laboratory and are based on the principle of application of a composite material directly to the prepared tooth surface in the dental clinic. Indirect laminate veneers may be produced from composite materials or ceramics, which are cemented to the tooth with an adhesive resin. In this case report, direct composite laminate veneer technique used for patients with esthetic problems is described and six-month follow-up are discussed. As a conclusion, direct laminate veneer restorations may be a treatment option for patients with the esthetic problems of anterior teeth in case similar to those reported here

A bibliometric analysis of the 100 most-cited articles in dental materials journals

Background: Bibliometric studies are important as they provide an overview of research and scientific activity in a specific field. But studies of this type to determine the characteristics of the most cited articles in dental materials journals are completely lacking. Aim: To analyze the characteristics of 100 most-cited articles in dental materials journals since its inception through April 2019. Material and methods: Google scholar database was used to retrieve the list of journals titled with the term ‘‘dental materials”. A search was then conducted under "Publication Name" for each of the selected journals, and the articles were grouped by the category "Times Cited". The 100 highly cited papers published in five journals were contemplated in the eventual inquiry. The final collection was subjected to further scrutiny to determine the nature and characteristics of the documented revelations regard to journal name, year of publication, authors and their country, type of article, and area of research. Results: The 100 most-cited articles were published between 1985 and 2016 with maximum publications during 2001-05. The number of citations was ranging from 1926to 304. Only Dental Materials (97), Dental Materials Journal (3), shared the list.  The United States tops the list with 25 articles followed by Germany (12) and Belgium (11). Dental composites and adhesives were the most commonly addressed topics in dental materials journals. Conclusions: This bibliometric analysis connoted the evolving and interesting research trends in dental material science

Effect of plant extract denture cleansing on heat-cured acrylic denture base resin: An in vitro study

Aim: Various chemical solutions have been recommended for denture disinfection; however, the immersion effect on the properties of denture base resin may also have effect on strength of the resin material. The purpose of this in vitro study was to compare and evaluate the flexural strength of heat-cure acrylic denture base resin by combination method of denture cleansing and plant extract immersion. Materials and Methods: In this study, ninety specimens of heat-cure acrylic denture base resin material were fabricated with dimensions of 65 mm × 10 mm × 3.3 mm. The specimens were divided into three groups, namely, Group I–III of thirty specimens each and were immersed in distilled water, denture cleanser, and thyme essential oil, respectively. The flexural strength of specimen was evaluated. Results: Natural plant extract showed better flexural strength than immersed in denture cleanser and control group but statistically was not significant. Conclusion: The study concluded that plant extract, namely, thyme essential oil, showed better flexural strength than combination method and can be used as denture cleanser
