The number of tooth whitening products available to patients has grown dramatically during recent years. While peroxide is the primary agent found in products that bleach and remove intrinsic sources of discoloration, various ingredients are incorporated in formulations to remove and inhibit extrinsic sources of tooth discoloration, ie, tooth stain. Recently, an advanced antitartar ingredient w...

introduction: a desirable quality of any endodontic sealer is its ability to be tooth color friendly. therefore the aim of the present study was to evaluate the tooth discoloration potential of a nano zinc oxide-eugenol (nzoe) sealer. methods and materials: in order to evaluate tooth discoloration, the pulp chamber of 60 human maxillary central and lateral incisors were filled with one of the s...

INTRODUCTION The aim of this in vitro study was to evaluate the tooth discoloration induced by calcium-enriched mixture (CEM) cement and mineral trioxide aggregate (MTA). METHODS AND MATERIALS Forty five endodontically treated human maxillary central incisors were selected and divided into three groups (n=15) after removing the coronal 3 mm of the obturating materials. In the MTA group, white...

Aesthetics are of utmost importance including tooth colour to the people these days. Dentists are called upon to respond to requests from patients who wish to enhance their smiles. In this review of the literature, various causes of tooth discoloration, bleaching of vital and non vital teeth and biological hazards are discussed.

We described a combined periodontal-endodontic lesion, which was caused by a palatogingival groove and an additional root. An interdisciplinary approach involving endodontic therapy, mineral trioxide aggregate (MTA) filling, root resection, guided tissue regeneration, and papillary reconstruction was used for the case. The tooth presents morphologically and functionally normal except tooth disc...

OBJECTIVES Treatment of dental discolorations with external bleaching is becoming very common in dentistry, however, possible irreversible alterations on enamel surface due to bleaching procedures is a topic of discussion. The aim of this study was to evaluate the clinical effects of bleaching by measuring the dental plaque accumulation on human enamel and tooth discoloration in vivo. STUDY D...

When a tooth shows discoloration and does not respond to the cold test or electric pulp test (EPT) after a traumatic injury, its diagnosis can be even more difficult due to the lack of proper diagnostic methods to evaluate its vitality. In these case reports, we hope to demonstrate that ultrasound Doppler might be successfully used to evaluate the vitality of the tooth after trauma, and help re...

OBJECTIVES The aim of this study was to evaluate tooth discoloration caused by contact with a novel injectable mineral trioxide aggregate (MTA)-based root canal sealer (Endoseal; Maruchi, Wonju, Korea) compared with a widely used resin-based root canal sealer (AHplus; Dentsply De Trey, Konstanz, Germany) and conventional MTA (ProRoot; Dentsply, Tulsa, OK, USA). MATERIALS AND METHODS Forty sta...
