Patients who present with a single discolored tooth represent a significant restorative challenge. These case reports describe an economic and conservative treatment option for these patients. The situations presented demonstrate techniques for bleaching with carbamide peroxide in a traditional nightguard or with an inside-outside technique to achieve acceptable esthetic results on isolated nonvital discolored teeth. Although these techniques may not be effective in all cases, they do not compromise or eliminate any future treatment options.
出现单颗牙齿变色的患者面临着重大的修复挑战。这些病例报告描述了针对这些患者的一种经济且保守的治疗选择。所呈现的情况展示了在传统夜用护齿器中使用过氧化脲漂白的技术，或使用由内而外的技术，以在孤立的非活髓变色牙齿上获得可接受的美学效果。尽管这些技术可能并非在所有情况下都有效，但它们不会损害或消除任何未来的治疗选择。
