background: although studies have shown that porcelain veneers are very effi cient for treating discolored teeth, they did not address in particular the minimum thickness of a multilayer ips e.max press (ivoclarvivadent, schaan, liechtenstein) restoration required to mask discolored tooth. the aim of this study was to determine the minimum thickness of a multilayer porcelain restoration require...

Introduction: Internal bleaching is a treatment option for wightening endodontically treated discolored teeth. Cervical resorption is one of the side effects of this method.The aim of this study was to compare the sealing ability of resin composite and light-cured resin modified glass ionomer (RMGI) as intra-orifice barriers in internal bleaching. Materials &Methods: In this study, 34 single...

Introduction: Dental fluorosis is a condition which occurs due to exposure fluoride than required.The begins at the first eight years of life leads an eruption discolored teeth with stains from yellow dark brown, surface irregularities and noticeable pit.

OBJECTIVE This study therefore assessed the effects of anterior tooth discoloration on the psychosocial well-being of adolescents with a view to providing information that will aid the preve...

The instruments clinically available for the diagnosis of approximal caries lesions are inadequate to detect lesions early and quantitatively. The aim of this study was to investigate whether wavelength-dependent light scattering and absorption of carious tissues may be utilized for the quantitative diagnosis of these small approximal caries lesions. Seventeen extracted premolar teeth were tran...

Treating pathological defects that are caused by resorption in teeth can be challenging. The task is complicated further if the resorption extends beyond the restrains of the root. The aim of this report is to describe a case of extensive internal tunneling resorption (ITR) associated with invasive cervical resorption (ICR) in a maxillary right lateral incisor and its nonsurgical treatment. A 2...

Objective: A powder jet deposition (PJD) process can be used to create a thick hydroxyapatite (HA) layer on the human tooth surface. The purpose of this exploratory trial was to evaluate the safety and efficacy of the hydroxyapatite layer formed by a new dental treatment system for cases of caries, dentin hypersensitivity, or discolored teeth. Methods: A single facility, non-blinded study compa...

The aim of this study was to examine whether brownish crown and root discoloration of wisdom teeth was related to treatment of acne with tetracyclines. For this purpose, 17 discolored third molars from nine patients were embedded without being decalcified, ground along the tooth axis, and examined using fluorescence microscopy. A thorough medical history served to determine the start and durati...

Red chili is amongst the important market commodities mainly for its pungency, color and their respective therapeutic significances. However, the persistence of aflatoxin contamination in chilies at higher levels is raising the health and economic risks. Post harvest practices may play as crucial role to make the red chilies physically damaged that may lead to increase the levels of aflatoxins....
