Evaluation of extrinsic tooth discoloration.

Extrinsic brown tooth discolorations are frequently detected in connection with antibacterial agents used for chemical plaque control. The present investigation confirmed the staining ability of an antibacterial quarternary ammonium salt, benzethoniumchloride, used as a 2% additive to a dentifrice. A weak chelator did not alter the discoloration tendency. Extrinsic discoloration was evaluated both by direct inspection, from color photographs and by using a microphotometric technique. The discoloration tendency was well demonstrated by all three techniques. Evaluation from the color photographs, however, may be preferable in epidemiological surveys while the microphotometric technique may possess certain advantages in detailed experimental discoloration studies.

Minocycline-associated tooth discoloration in young adults.

After observing a patient with adult-onset tooth discoloration coincident with minocycline administration, we retrospectively surveyed a cohort of patients with severe cystic acne during therapeutic trials with isotretinoin. Four of 72 patients who had minocycline therapy during adolescence were found to have minocycline-associated tooth discoloration, which occurred in one case after only four weeks of treatment. Thus, minocycline must be considered as an uncommon cause of tooth staining in adults.

Bleaching teeth: history, chemicals, and methods used for common tooth discolorations.

This article reviews the history of bleaching teeth to lighten tooth color. The last 2 years have seen a dramatic increase in new bleaching methods and bleaching chemicals. The following categorizes bleaching chemicals and methods in relation to their use in treating common tooth discolorations. Special attention is given to home bleaching methods.

ABO blood group incompatibility and primary tooth discoloration.

A case report of discolored anterior primary teeth is presented. Medical history and clinical findings suggest an etiology of hemolytic anemia and jaundice secondary to ABO blood group incompatibility. There are no previous reports of tooth discoloration resulting from ABO blood group incompatibility.

[Tooth discoloration possibly caused by medication (tetracycline)].

In this study, the following procedures to remove discoloration were performed, using a modified version of the Walking-Bleach method. 1) The stained dentin was removed as much as possible. 2) Effect of decolarion were enhanced by etching on the dentin. 3) After a desirable color was obtained, total etching and restoration with adhesive composite resin were conducted for strengthening and aesthetic recovery. Tooth discoloration due to tetracycline, 3 subjects in this study, has previously been regarded as difficult to bleach, could be carried out satisfactorily with few appointments. Consequently, this modification of the Walking-Bleach method was considered as one of effective methods.

[Analysis of deciduous tooth discoloration, before and after liver transplantation].

130 children aged between 5 months and 15 years were orally examined in our Department in view of preparation for hepatic pre-grafts, before being given a graft by Professor J.-B. Otte and his team at the Paediatric Surgery Department. 70% of these children age from 5 months to 3 years. We report here two cases of dysplasia and dyschromia, observable in young children, which appear to us to be particularly convincing.

Tooth discoloration resulting from long-term tetracycline therapy: a case report.

Administration of tetracycline to children or pregnant women is known to adversely affect the color of developing teeth. This case report suggests the possibility that discoloration from tetracycline may not be limited to tooth development in the child, but may also affect the adult dentition. When given over long periods of time in adults, the tetracycline molecule is incorporated into the continuously forming secondary dentin. It is possible that chronic sun exposure of the incorporated tetracycline may cause the formation of a reddish-purple oxidation product, resulting in discoloration of the permanent teeth.

[Modern views on treating tooth discoloration from tetracycline].

The Authors, having widely examined literature about genesis and methods of treatment of the tetracycline-induced discoloration of the teeth, had clinically studied a new way of bleaching discolored teeth called B.V. Bleaching Vital, they also described the execution's technique of this method.

[Treatment of tooth discoloration in adolescents with mucoviscidosis].

The very high density of adolescents suffering from mucoviscidosis in the North Finistère, and followed at the Roscoff Hélio-Marin Centre, has led the authors to deal with the dental colourations of these patients. The severity this tetracycline, dyschromy, varies with the intake of the medicament. Several therapies are possible, the technique of composite laminate facings is the most used as it adapts particularly well to the cases of these adolescents.

An in vitro comparison of different bleaching agents in the discolored tooth.

Extracted teeth with intact crowns were stained to compare and evaluate the effectiveness of four bleaching agent combinations. Forty-two permanent and 12 deciduous teeth were used. The bleaching agents were placed into coronal pulp chambers and then evaluated and rated at 1-, 3-, 7-, and 14-day and 6-month intervals. New sodium perborate combined with fresh Superoxol was the most effective bleaching agent with 93% success (the final shade was as light as the prestained shade). New sodium perborate and 1-yr-old Superoxol was 73% successful. New sodium perborate with distilled water and old sodium perborate with distilled water were both 53% successful. Deciduous teeth demonstrated a response to bleaching agents similar to that of permanent teeth. Color regression after 6 months was found in 4% of the cases. When it occurred, the degree of color regression was minimal.

Vital bleach of hemorrhagic discoloration.

An unusual case is presented of a maxillary central incisor with hemorrhagic discoloration that was successfully treated with the thermocatalytic vital bleach technique. This case emphasizes the need for a thorough radiographic and clinical examination to include vitality tests when a patient presents with a discolored tooth.
