RESUMO
OBJECTIVE: The current clinical trial was conducted to evaluate the effect of proximal indirect restorations in endodontically treated posterior teeth with deeply located margins following deep margin elevation compared to surgical crown lengthening. MATERIAL AND METHODS: Deep proximal cavities in endodontically treated posterior teeth were randomly assigned into two groups; deep margin elevation (DME) or crown lengthening (CL). The clinical attachment level (CAL), probing depth (PD), bleeding on probing (BOP), crestal bone level (CBL), and secondary caries were evaluated at the baseline, 1, 3, 6, 9, and 12 months. RESULTS: A total of 20 proximal cavities were included in the study; there was no significant difference between the two groups regarding mean CAL values at the baseline and 1 month, while there was a significant difference between the two groups in all other periods. Regarding the PD, there was no statistical significance between the two groups except at 9 and 12 months, where CL showed higher mean PD values than DME. There was no statistically significant difference in BOP or CBL between the two groups. CONCLUSIONS: DME and CL are considered clinically successful with favorable biologic responses. CLINICAL RELEVANCE: The deep margin elevation approach could provide a more conservative solution when relocating deeply seated cervical margins in a more coronal position. DME reduced the number of visits and time needed for the restoration of endodontically treated teeth. Surgical crown lengthening remains a gold standard procedure in the re-establishment of the supracrestal tissue attachment, especially in cases where cervical margins are beyond the elevation capacity.

AIM: This study was conducted to evaluate the remineralization potential of Remin Pro Forte vs Remin Pro remineralizing agents on white spot lesions (WSLs) post-orthodontic treatment. MATERIALS AND METHODS: Twenty patients with post-orthodontic WSLs were divided into the following two equal groups based on treatment (n = 10): (1) A 3-month program of hydroxyapatite, fluoride, xylitol, ginger, curcuma-containing cream (Remin Pro Forte) as intervention group; (2) A 3-month cream regimen including hydroxyapatite and fluoride, xylitol (Remin Pro) as control group. The main outcomes including caries regression (assessed by ICDAS II), mineral content (assessed by VistaCam iX camera), and color of WSLs (assessed by digital image analysis by Adobe photoshop) were measured at the time of enrollment and 1, 2, and 3 months afterward. Mann-Whitney test used to compare between tested groups. The statistical significance was set at p <0.05. RESULTS: Both Remin Pro Forte and Remin Pro elicited much better caries regression and significantly higher mineral content in WSLs over a 3-month period (p <0.05). However, the difference in mineral content of WSLs between groups did not reach statistical significance (p = 0.414). In both experimental groups, the appearance of WSLs improved significantly (p <0.05). CONCLUSION: Both Remin Pro Forte and Remin Pro were successful in reducing caries, increasing mineral content, and enhancing the appearance of demineralized enamel, indicating that both products could be suggested for post-orthodontic WSL management. CLINICAL SIGNIFICANCE: Natural herbal products could be employed as remineralizing agents and included into tooth preventive measures. It is a less harmful alternative to traditional chemical remineralization methods.
