The aesthetic choice of anterior teeth is always a challenging work. Matching the size, colour, shade and shape of the restored tooth with those of the natural teeth is a dilemma. In this report patient's own natural teeth were used as a substitute in an immediate removable partial denture. Immediate replantation in aesthetic region like maxillary anterior, can hence, be considered primarily significant. The replacement of an anterior tooth is most technique sensitive, as it involves the patient's expectations, which demands artificial tooth that are identical to his/her natural tooth. Therefore, in this case presentation patient's aesthetics, function and psychological wellness was given attention.

Sweptsource optical coherence tomography (SS-OCT) permits cross-sectional observation of surface/ subsurface characteristics of enamel including early carious lesions (ECL) or remineralization non-invasively.This study aimed to visually compare the cross-sectional remineralizing efficacy of various agents on ICDAS-II scores-1&2 by using SS-OCT and histology. Methods: Baseline SS-OCT (grey-scale/false-colour) and histology was performed on the randomly selected two samples with scores-1&2. Four remineralizing agents [fluoride-varnish (FV), CPP-ACP, nanohydroxy-paste (NHP) and silver-diamine-fluoride (SDF)]were evaluated for 2-or 6-weeks post-remineralization using SS-OCT and histology. Results: Score-1&2 baseline SS-OCT images showed a linear-shaped demineralization with dentino-enamel junction (DEJ) visible; and bowl-shaped demineralization with DEJ invisible respectively. Remineralizing agents were assessed on the basis of their ability to remineralize the surface, subsurface and made visualize the DEJ in score-2. SS-OCT showed an outer growth layer in post-remineralization score-1, 2-weeks samples with FV and NHP. All the agents showed progressive subsurface remineralization in 6 weeks. Active lesions showed rapid uptake of minerals on surface. Subsurface mineralization in pigmented score-2 matched sound enamel with NHP and SDF. Surface remineralization was comparable in FV and SDF followed by NHP. SDF demonstrated deeper subsurface remineralization followed by NHP and CPP-ACP. Conclusion: SS-OCT images correlated to histology. SS-OCT could monitor surface/subsurface in-situde/remineralization activity non-invasively.
