Reproducibility of grading systems in oral epithelial dysplasia

2012

Objective: To assess inter and intra observer variability in grading oral epithelial dysplasia (OED) using Smith and Pindborg grading system, WHO classification system and Brothwell DJ et al. classification system. Study design: In the study 45 histological tissues of dysplasia, 15 each of mild, moderate and severe dysplasia were coded and blindly graded by three observers in three grading systems. Further on the same observers graded 15 slides again of the previous 45 for analyzing the reproducibility in the three grading systems. The individual significance of various indicators of dysplasia among various grades of dysplasia was also assessed. Result: Inter observer agreement was signific…

The effect of oral contraceptives on orthodontic tooth movement in rat

2012

Introduction: The purpose of this study was to investigate the effect of ethinyl estradiol/norgestrel � used in some oral contraceptives- on orthodontic tooth movement in Wistar rats. Material and Methods: Forty eight female three-month old Wistar rats with an average weight of 250�25gr were divided into two experimental and control groups. One week prior to appliance insertion and during the appliance therapy period, 100 mcg/kg/day of ethinyl estradiol and 1mg/kg/days of norgestrel were administered to the experimental group by gavage; meanwhile the control group received an equivalent volume of Sodium Chloride 0.9 % (Saline). Maxillary central incisors were tipped distally by insertion of…

Medico-legal study of death in custody by excited delirium. A case report

2014

En este artículo exponemos los resultados de la autopsia de un varón joven que falleció en el hospital por un cuadro de delirium agitado. Es un síndrome caracterizado generalmente por agitación psicomotriz, agresividad y puede producir muerte súbita, en ocasiones durante la aplicación de métodos de contención mecánica por los Cuerpos de Seguridad del Estado o personal sanitario. Está típicamente asociado al consumo de drogas de abuso, como la cocaína. En estos casos, estará incluida en el grupo de muertes en custodia, que es aquella que se produce cuando la víctima se encuentra privada de libertad. Tiene una indudable repercusión médico legal, puesto que se considera prototipo de muerte sos…

Extraction and immediate placement of root analogue zirconia implants: an overview

2011

Dental implants constitute a well-established approach for replacement of lost teeth with titanium being the most favored material for implantation. However, titanium has its limitations in esthetically demanding cases and neither the form nor material of such implants has changed much over the past 40 years. Immediate implantation has been introduced to overcome the disadvantages of conventional implantation which in turn has many disadvantages owing to the incongruence of the implant to the extraction socket. Today, there is scientific evidence that zirconia dental implants osseointegrate well and offer many advantages over titanium implants. The successful use of zirconia ceramics in ort…

Foreign body granulomatous reactions to cosmetic fillers

2012

Introduction: The use of different facial cosmetic fillers has increased in recent years. The introduction of apparently inert substances in the epidermis can give rise to foreign body granulomatous reactions. Objetives: A literature review is made of the foreign body granulomatous reactions to cosmetic fillers. Material and Methods: A PubMed-Medline search was made using the following keywords: “granulomatous reactions”, “foreign body reactions”, “esthetic fillers”, “cosmetic fillers”. The search was limited to articles published in English and Spanish during the last 10 years. A total of 22 articles were reviewed. Results: A great variety of substances have been found to give rise to fore…

Depression and anxiety disorders in a sample of facial trauma: A study from Iran.

2015

Background: Various studies have shown that such patients are susceptible to psychological problems and poor quality of life. The aim of the present study was to evaluate and compare the prevalence of depression and anxiety disorders and quality of life in a group of facial trauma. Material and Methods: In the present cross-sectional study Hospital Anxiety and Depression Scale (HADS) and Oral Health Impact (OHIP-14) questionnaires were used. In this study, fifty subjects were selected from the patients with maxillofacial traumas based on the judgment of the physicians, referring to hospitals in Kerman and Rafsanjan during 2012-2013. In addition, 50 patients referring to the Dental School fo…

Fluoride release and uptake abilities of different fissure sealants

2016

Background: The long-term capability of resin sealants and glass ionomer cements to release fluoride is associated to a reduction in pit and fissure caries. The regular use of fluoride varnishes/toothpastes can result in the absorption of fluoride into the sealant. The objective of the present study was to assess the fluoride release/uptake capacities of different fissure sealants. Material and Methods: Three different fissure sealants (Fuji Triage/GC, Fissurit FX/Voco and Grandio Seal/Voco) were examined. Ten discs of each material were prepared. Each disc was incubated with distilled water and then the solution analyzed for diluted for fluoride concentration, using a combination of fluori…

Zirconia in fixed prosthesis. A literature review

2014

Statement of problem: Evidence is limited on the efficacy of zirconia-based fixed dental prostheses. Objective: To carry out a literature review of the behavior of zirconium oxide dental restorations. Material and Methods: This literature review searched the Pubmed, Scopus, Medline and Cochrane Library databases using key search words “zirconium oxide,” “zirconia,” “non-metal restorations,” “ceramic oxides,” “veneering ceramic,” “zirconia-based fixed dental prostheses”. Both in vivo and in vitro studies into zirconia-based prosthodontic restoration behavior were included. Results: Clinical studies have revealed a high rate of fracture for porcelain-veneered zirconia-based restorations that …
