A prospective study comparing topic platelet-rich plasma vs. placebo on reducing superficial perioral wrinkles and restore dermal matrix

Introduction: The goal of our prospective study was to assess the efficacy of the topical Platelet-rich plasma on reducing superficial perioral wrinkles and restoring the dermal matrix. Materials and methods: 50 women with moderate to severe perioral wrinkles were treated on the perioral area by a single session of fractional CO2 laser skin resurfacing plus intradermal injection of prp. 25 patients (group 1) applied topically prp twice a day for 12 weeks as post laser treatment. 25 (group 2) applied gentamicin and betamethasone twice a day for the first 7 days and then hyaluronic acid gel for the following 12 weeks. Results: In group 1, moisture (p < 0.001), amount of collagen fiber (p < 0.001) skin elasticity (p < 0.001), PSAl (p < 0.001) and SSAl (p < 0.001) improved significantly. In group 2 all the parameters investigated improved but did not reach significant difference. Discussion: Our medical device with a plasma-like formulation is able to maintain prp active for a period of 7 days so patients are able to apply topically growth factors at home. Conclusions: Our prospective study proves that the use of topical prp reduces superficial perioral wrinkles and restore dermal matrix when used at home for 12 weeks.

Rehabilitation with implant-retained removable dentures and its effects on perioral aesthetics: a prospective cohort study

Background

The onset of perioral wrinkles often prompts patients to request treatment. This aesthetic deterioration linked to aging may be associated with tooth and alveolar bone loss in fully edentulous patients.

Purpose

To evaluate perioral wrinkles before and after maxillary and mandibular rehabilitation with implant-retained dentures in fully edentulous patients.

Methods

In this prospective cohort, single-center, blinded study, patients requiring maxillary and mandibular rehabilitation with implant-retained dentures were enrolled. The patients were photographed in the same position before and after oral rehabilitation. Wrinkles were evaluated in the photographs by blinded observers using validated rating scales. The following parameters were analyzed: upper and lower radial lip lines, marionette lines, upper and lower lip fullness, nasolabial folds, corner of the mouth lines, and the labiomental crease. Statistical analysis was performed using the Wilcoxon signed ranks test for paired data, with P<0.05 considered significant.

Results

Upper and lower implant-retained dentures were applied in 31 patients (15 males; mean ± standard deviation age 62.13±8.69 years, range 47–77 years). The oral rehabilitation procedures significantly improved (P<0.05) the upper and lower radial lip lines, marionette lines, upper and lower lip fullness, the nasolabial folds, and the corner of the mouth lines.

Conclusion

Maxillary and mandibular rehabilitation with implant-retained dentures in fully edentulous patients improves perioral aesthetics. Patients requiring oral rehabilitation and desiring perioral aesthetic improvement could benefit from treatment with this type of prosthesis.
