Abstract
Discoloration of teeth, especially maxillary incisor, that appears in various types and severties causes a major problem in esthetic aspect. The attributing factors can be classified into extrinsic and intrinsic factors: chewing tabacco, coffee,
and tea
are some example of the former, and intake of tetracycline, fluorosis, pulpal necrosis, iatrogenic agents, systemic condition, genetic factors, and aging process are, the latter.
Treatment of a discolored vital tooth include full crown restoration, direct or indirect venner restoration, vital bleaching, and so on. Several vital bleaching technuques have been developed since Capple first introduced a bleaching case using
oxalic
acid in 1877. Nowadays, the technique that utilizes both hydrogen peroxide and bleaching light is most preferred. The pulpal effect of vital bleaching medicaments and lights have been controversal, but it has been also noted that 98°F-141°F,
30~35%
hydrogen peroxide causes only mild reversible inflammation.
In these cases, 12 and 10-year-old sisters showed generalized brown discoloration of teeth. Their primary dentitions were normal color, and there were no special systemic disease to be noticed. There were no history of discolored teeth. The exact
cause
could not be found, but tooth color was improved by vital bleaching of four times. For the better esthetic results, combination therapy of repeated bleaching and veheering restoration is recommended.
