Background: Acne vulgaris is a chronic inflammatory disorder of the pilosebaceous unit that commonly affects adolescents and adults, often resulting in post-inflammatory hyperpigmentation, scarring, and significant psychosocial distress. Chemical peels have emerged as effective adjunctive treatment modalities because of their keratolytic, comedolytic, anti-inflammatory, and sebostatic properties. Among the available agents, the combination of salicylic acid and mandelic acid (SAMA peel) and acetic acid-based Black peel are widely used; however, comparative evidence regarding their efficacy and safety remains limited. Aim and Objectives: To compare the efficacy and safety of 20% salicylic acid–mandelic acid (SAMA) peel versus 8% acetic acid (Black peel) in the treatment of mild to severe acne vulgaris.Materials and Methods: A prospective observational split-face comparative study was conducted on 30 patients with mild to severe acne vulgaris from March 2023 to December 2023 at a tertiary care hospital. SAMA peel was applied to the right side of the face, while Black peel was applied to the left side at 15-day intervals for six sessions. Patients were evaluated over 12 weeks using the Michaelson Acne Score (MAS), adverse effects, and patient satisfaction. Statistical analysis was performed using SPSS version 22.0. Results: Among the 30 participants, females predominated (24/30), and Grade II acne was the most common presentation (23/30). Oily skin (26 patients) and stress (21 patients) were the most frequent associated risk factors. The mean MAS decreased from 37.3 to 9.2 on the SAMA-treated side and from 34.2 to 7.7 on the Black peel-treated side after 12 weeks. Most patients were satisfied with both treatments, with no participant reporting dissatisfaction. SAMA peel was associated with more dryness (6 vs. 2), erythema (4 vs. 0), and burning (2 vs. 0), whereas irritation occurred equally in both groups (1 each). Conclusion: Both SAMA peel and Black peel were effective and well-tolerated treatment modalities for mild to severe acne vulgaris. While both demonstrated significant clinical improvement and high patient satisfaction, Black peel showed a comparatively better safety profile with fewer treatment-related adverse effects, making it a promising alternative for the management of acne vulgaris.

Background: Edentulism significantly impairs oral function, aesthetics, and quality of life in elderly patients. Conventional complete dentures often present limitations in retention and stability, whereas implant-supported overdentures offer improved prosthetic performance. This study aimed to compare patient satisfaction between complete dentures and implant-supported overdentures in patients aged 50–70 years. Methods: A prospective comparative study was conducted among 100 completely edentulous patients divided into two groups: complete denture (n=50) and implant-supported overdenture (n=50). After a 3-month adaptation period, patient satisfaction was assessed using a standardized questionnaire evaluating comfort, stability, mastication, aesthetics, and overall satisfaction. Statistical analysis was performed using independent t-test and chi-square test, with p<0.05 considered significant. Results: Implant-supported overdentures showed significantly higher satisfaction scores compared to complete dentures across all parameters. Mean overall satisfaction was 8.7 ± 0.8 in the implant group versus 6.6 ± 1.3 in the complete denture group (p<0.001). Comfort, stability, and masticatory efficiency were also significantly improved in the implant group (p<0.001). Patients with implant overdentures demonstrated better ability to chew hard foods and reported higher aesthetic satisfaction. Conclusion: Implant-supported overdentures provide superior functional and patient-reported outcomes compared to conventional complete dentures. They significantly enhance comfort, stability, and quality of life, making them a preferred treatment modality for edentulous patients aged 50–70 years, despite higher cost and surgical considerations.
