NEETMDSThe key clinical and radiographic findings are pulp chamber obliteration (calcific metamorphosis) with normal periapical and periodontal ligament spaces, indicating a vital, but discolored, tooth. Since the tooth is vital and has no evidence of pathology requiring root canal treatment, a conservative cosmetic solution like a porcelain veneer is the most appropriate management to address the discoloration after external bleaching has failed. Root canal treatment is not indicated for a vital tooth without pulpal pathology.

Conservative DentistryFor class V composite restoration, the best method to retract gingiva is by using a rubber dam. This provides isolation, visualization, and moisture control, which are crucial for successful adhesive techniques. While other methods like retraction cords or electrosurgery may be used in some cases, they are not the most suitable for routine class V restorations.
