11/118. Whitening of endodontically untreated calcified anterior teeth.

    Definitive treatment for whitening endodontically untreated anterior teeth with dystrophic calcification is provided by removing the coronal sclerotic dentin and utilizing internal and external bleaching as necessary. ( info)

12/118. Secondary caries: a literature review with case reports.

    The clinical diagnosis of secondary caries is by far the most common reason for replacement of restorations, but the scientific basis for the diagnosis is meager. The purpose of this article is to review the literature on secondary (recurrent) caries and present case reports to document the problems encountered in the clinical diagnosis of secondary caries. The literature on secondary caries was critically reviewed and subdivided into clinical diagnosis, location of secondary lesions, histopathology, microleakage, and microbiology. The case reports included restorations that were scheduled to be replaced because of secondary caries or stained margins of composite restorations. The lesions were photographed preoperatively and postoperatively. Based on the limited literature available, secondary caries appears to be a localized lesion similar or identical to primary caries. It is most often localized gingivally on restorations. Narrow gaps, crevices, ditches, and "microleakage" do not lead to secondary caries, but wide voids may. Secondary caries is difficult to diagnose clinically. Consistency or hardness and discoloration of dentin and enamel are the best parameters. Secondary caries is the same as primary caries located at the margin of a restoration. ( info)

13/118. Dental findings in Morquio syndrome (mucopolysaccharidoses type IVa).

    Morquio syndrome is a disorder of mucopolysaccharide metabolism with specific skeletal features. The clinical and radiographic appearance of the teeth resembles hypoplastic amelogenesis imperfecta with thin enamel of normal radiodensity. The dental practitioner has a part to play in collaboration with medical colleagues in the recognition and diagnosis of this condition. ( info)

14/118. Microabrasion of teeth with discoloration resembling hypomaturation enamel defects: four-year follow up.

    Microabrasion with 18% HCl and pumice to remove enamel dysmineralization and improve esthetics is an accepted and effective treatment. This technique can probably be extended even to generalized defects resembling hypomaturation amelogenesis imperfecta that appear on all erupted teeth. Five children aged 9 to 11 with two types of enamel-hypomaturation probably due to developmental defects were treated successfully by microabrasion, with marked improvement of the discoloration. The patients were followed for up to four years. During this period, no tooth-sensitivity or staining was noted. The teeth looked healthier and shinier. ( info)

15/118. enamel microabrasion: a new approach.

    enamel microabrasion is a proven method of removing superficial intrinsic enamel discoloration defects. The method is safe, easily performed, and causes no discomfort for the patient. A new commercially available microabrasion system has been introduced by Ultradent Products Inc. In addition, a new tooth isolation material is available, along with a visible light-activated in-office hydrogen peroxide solution. This article describes these new products and documents tooth-color correction for two young patients using this new tooth-color correction approach. ( info)

16/118. An innovative chairside bleaching protocol for treating stained dentition: initial results.

    For years, investigators have attempted to develop a predictable means of bleaching pathologically and nonpathologically stained dentition. While previous efforts have modified the concentration of the bleaching material, the duration of the procedure, and the manner by which the bleaching agent is activated, the ability to affect a significant shade improvement remains an elusive objective. This article demonstrates an innovative technique used to influence the penetration of oxygen ions into the tooth enamel, which may resolve this clinical dilemma. ( info)

17/118. Trauma quiz. Terribly troublesome, trauma teeth.

    Unfortunately, we come across many traumatised teeth during our practising career. Some of these traumatic injuries are rather simple to treat whereas others provide us with a real challenge. It is absolutely essential that the diagnosis of the injury be known before any treatment is attempted. When it comes to trauma, however, defining the exact form of treatment can often be very difficult. In this paper I will discuss some of the cases that I have managed and leave it up to YOU to decide whether my treatment has been correct, incorrect or whether there is some other form of treatment that we have at our disposal that could have been attempted.

18/118. A newly recognized syndrome of skeletal dysplasia with opalescent and rootless teeth.

    A Thai girl with skeletal dysplasia and dental anomalies was seen. Her anomalies consisted of disproportionately short stature, short neck, broad and depressed nasal bridge, broad chest in the anteroposterior dimension, kyphosis, widely spaced nipples, and protruded abdomen. Radiographic testing indicated that she had a large sella turcica, platyspondyly, hypoplastic acetabulum, and a small body of mandible. Both her deciduous and permanent teeth were equally opalescent, and most were rootless, with root development of the mandibular teeth more severely affected. Some maxillary roots were extremely short and tapered. Hypodontia was also observed. These findings represent a unique and hitherto undescribed syndrome of skeletal dysplasia with concomitant dental anomalies. ( info)

19/118. An unusual staining of the tooth roots: a case report with histological and micro-analytical studies.

    The discoloration of tooth roots is rare. We report here a 22-year-old Japanese woman with blackish-brown staining of the roots of the upper and lower third molars. Staining was found in the dentin and cementum. Electron probe X-ray microanalysis showed no significant difference in the composing elements between the stained tooth root and control tooth. Fluorescent bands coincided with staining in the dentin of the root and cementum along the incremental lines under confocal laser-scanning microscope. ( info)

20/118. Bleaching primary teeth with 10% carbamide peroxide.

    Bleaching teeth with 10% carbamide peroxide in a custom-fitted tray has been popular for more than 10 years. However, primary teeth are seldom considered for bleaching due to the need for compliance by the child and the natural whiteness of the primary teeth. This report describes an indication-teeth darkened from trauma-as well as the technique and outcome for bleaching discolored primary teeth. ( info)
