Natural teeth wear opposite to glazed and polished ceramic crowns: A systematic review
It is a major concern to select a proper ceramic with acceptable strength and esthetic and minimumantagonist wear. Therefore, different ceramics were introduced to obtain these advantages withvarious surface treatments. The aim of this study is to evaluate and report the wear behavior ofpolished and glazed feldspathic and zirconia crowns in published articles up to 2020. Five electronicdatabases which were used in this research were MEDLINE (via PubMed), Web of Science, CochraneLibrary, Embase, and Scopus from the starting date of databases to January 2020. The Keywords“zirconia,” “feldspathic,” “dental ceramic,...

Scanning electron microscopic evaluation of the effect of different root ‑end resection methods in the crack formation in root canals filled with mineral trioxide aggregate or calcium‑enriched mixture cement
Conclusion: Based on the results of this study, the prevalence of crack in dentin is always significantlyhigher than its prevalence in the plug, and the prevalence of crack in the plug was similar in CEMand MTA; then, when there is an orthograde access to the root canal and surgery is likely in future,MTA and CEM can be placed in an orthograde technique and it just resects the root during surgery.Key Words: Dentine, pulp canal, retrograde obturation, root canal, ultrasonic surgery (Source: Dental Research Journal)

Comparative evaluation of net setting time and radiopacity in Fuji II (GC ‑Japan) restorative glass ionomer and Iranian glass ionomer
Conclusion: Net setting time and radiopacity of the glass ionomers were within the range of ISO9917 ‑1:2007. If all properties of the Iranian cement are set appropriately in future investigations,we propose to use it instead of Fuji II GIC. This has the additional benefit of being cost ‑efficient asIranian cement costs less than Fuji II cement.Key Words: Energy ‑dispersive X‑ray spectroscopy, Fuji II radiopaque, glass ionomer cements,particle size (Source: Dental Research Journal)

A comparative evaluation of oral health status among institutionalized totally blind children using different methods – A randomized clinical trial
Conclusion: Visually impaired children could maintain a respectable level of oral hygiene whentaught specialized methods. However, periodic reinforcement is mandatory for good oral hygienemaintenance. Hence, it is recommended to use the combination of Verbal, Braille, and Audio ‑Tactilemethod for the best treatment outcomes in these special children.Key Words: Blindness, oral hygiene, positive reinforcement, questionnaire (Source: Dental Research Journal)

Prosthetic rehabilitation of a midfacial defect with magnet ‑retained intraoral–extraoral combination prosthesis
It may not be possible to treat large maxillofacial defects by surgical reconstruction alone. Prostheticrehabilitation is invariably required to restore esthetics and function. Achieving adequate retention,stability, and support in these maxillofacial prostheses is a challenging task. This clinical reportdescribes prosthetic rehabilitation of a midfacial defect following surgical resection of squamouscell carcinoma. The intraoral defect was restored with a maxillary obturator prosthesis with salivaryreservoir, and the extraoral defect was restored with magnet ‑retained facial prosthesis having anacrylic resin framework a...

Comparing the functional efficiency of tooth ‑supported overdentures and implant‑supported overdentures in patients requiring oral rehabilitation: A systematic review
The aim of this article is to compare the functional efficiency of tooth ‑supported overdenturesand implant ‑supported overdentures in patients requiring oral rehabilitation. The comparativequantification of the improvement in functional efficiency is very difficult to assess because of thevariations in the study designs like the age of the population studied, the male ‑to‑female ratio, theoutcome measures used, the clinical setting in which the implant therapy was provided, oral statusof the subjects included and the type of implant therapy provided. In this systematic review, thearticles included compared the fun...

Resin ‑bonded bridge as a simplified approach to restore missing teeth in esthetic zone by conventional and digital techniques
One of the most challenging esthetic concerns in dentistry is conservative replacement of themissing anterior teeth. Although implants are considered to be a better treatment option forrehabilitation of such patients, resin ‑bonded bridges (RBBs) can conservatively restore the missingteeth and have thus gained popularity over the years. It consists of an artificial tooth with a wing ‑likeextension that is cemented to the adjacent teeth. There are various types of RBBs among whichMaryland bridge is the simplest and the popular most due to its micromechanical retention enabledby acid etching of both tooth and metal retai...
