BACKGROUND AND AIM: The aim of this study was to evaluate the effectiveness of different whitening toothpastes, focusing on the experimental ozonated toothpaste. MATERIALS AND METHODS: This laboratory study included a sample of 48 sound human molar teeth. Teeth were randomly assigned into four groups according to toothpaste treatment to be evaluated objectively (colorimetric method) and subject...

pulp tissues due to endodontic treatment may often lead to intrinsic staining. In such cases, cleaning procedures utilized to remove surface pigmentations are not effective and chemical bleaching is required to recover the original color. Nowadays, dental bleaching has been recognized as the most conservative treatment for discolored teeth.1, 2 In recent years, several products and techniques h...

This case report describes a patient with discolored and fractured composite resin restorations on the anterior teeth in whom substitution was indicated. After wax-up and mock-up, the composite was removed and replaced with minimally invasive ceramic laminates. An established and predictable protocol was performed using resin cement. Minimally invasive ceramic restorations are increasingly bein...

Early childhood caries (ECC) is the most common chronic disease condition in childhood and involves the presence of one or more decayed (noncavitated or cavitated lesions), missing (due to caries), or filled teeth in children under 72 months of age (American Academy of Pediatric Dentistry, 2010a). ECC is a multifactorial disease that is preventable and requires intervention by the nurse. When t...

In the era of antibiotic resistance, we need a naturally occurring substance like Ozone to treat infection without any toxic side effects. Interest of Ozone use in Medicine and Dentistry is due to its Anti-microbial, Disinfectant, Biocompatibility and Healing properties. Since ozone is a powerful oxidizer, it effectively kills Bacteria, Fungi, Viruses and Parasites. Ozone therapy has opened new...

Pachyonychia congenita (PC) is a rare autosomal dominant genodermatosis characterized by hyperkeratosis affecting the nails and palmoplantar areas, oral leucokeratosis, and cystic lesions. It is classically subdivided into two major variants, PC-1 (Jadassohn-Lewandowski syndrome) and PC-2 (Jackson-Lawler syndrome), according to the localization of the mutations in the KRT6A/KRT16 or KRT6B/KRT17...

Dental hard tissue is subject to variety of disorders. Dentinogenesis Imperfecta is one such disorder attributed to heredity. It is known to be an autosomal dominant trait. Teeth with such 'imperfect' dentin are liable to be weak and discolored. The disease has variable penetration and therefore can be expressed as a range of phenotypic manifestations from mild discoloration and chipping to fra...

Restoring primary teeth can be a strenuous task for many dentists who would like to have an esthetic, easy-to-use and relatively quick restoration for children. But, the restoration of carious, fractured or discolored primary incisors gives the dentist the satisfaction of knowing that he/she has restored the smile and self-confidence of a growing child. This article describes a technique which ...

Tooth discolouration results from varied and complex causes that are usually classified as being either intrinsic or extrinsic in nature. Extrinsic discoloration arises when external chromogens are deposited on the tooth surface or within the pellicle layer. Intrinsic discoloration occurs when the chromogens are deposited within the bulk of the tooth (usually in the dentine) and are often of sy...

OBJECTIVE Discolored ureteral stents are sometimes encountered in daily clinical practice; however, the mechanism(s) underlying the development of discolored ureteral stents remain unknown. In this study, we retrospectively analyzed the characteristics of discolored ureteral stents based on the results of a urinalysis and urine culture. MATERIALS & METHODS We identified a total of 26 patients...
