Clinical periodontal parameters such as probing depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP) were assessed to evaluate the efficacy of the treatments. <b>Methods:</b> Thirty patients with diabetes mellitus (DM), a history of poor glycemic control, and chronic periodontitis were enrolled in this clinical and microbiological split-mouth study. After conventional periodontal treatment, scaling, and root planing, the most severe sites on the premolar or molar teeth with periodontal pockets measuring ≥5 mm were selected and randomly divided into two groups: the <i>C. longa</i> extract gel group (with a concentration of 25 µg/g) and the photodynamic group (<i>C. longa</i> extract gel 25 µg/g irradiated with blue light energy density = 16.8 J/cm<sup>2</sup> for 120 s). All teeth were examined for clinical periodontal parameters data (PD, CAL, plaque index [PI], and BOP) and microbiological data (<i>Porphyromonas gingivalis</i>, <i>Prevotella intermedia</i>, <i>Fusobacterium nucleatum</i>, <i>Aggregatibacter actinomycetemcomitans</i>, and total bacteria), measured using TaqMan Multiplex real-time polymerase chain reaction, at weeks 0, 1, 2, and 12. The Mann-Whitney <i>U</i> test was utilized to compare clinical outcomes between groups, while the Wilcoxon Signed Rank test at a 95% confidence level was employed to analyze the amount of periodontal pathogens within the same group. <b>Results:</b> After the 12-week follow-up period, significant improvements were observed in all clinical parameters across both groups. However, the reduction in both CAL and BOP was significantly higher in the photodynamic group compared to the curcumin gel alone group, indicating enhanced periodontal health outcomes in the former. Microbiologically, both groups exhibited a decrease in total bacterial count and a reduction in periodontopathic bacteria. Importantly, the photodynamic group demonstrated a significant decrease in <i>F. nucleatum</i> and <i>P. intermedia</i> counts, key pathogens associated with periodontal disease progression. This suggests that photodynamic therapy (PDT), when used with curcumin gel, not only improves clinical parameters but also promotes a favorable shift in the periodontal microbial profile. <b>Conclusion:</b> Our findings highlight that PDT with curcumin gel as a photosensitizer (PS) is more effective than curcumin gel alone in achieving clinical attachment gain, reducing gingival inflammation, and suppressing specific periodontal pathogens.

Understanding patient sensitivity and comfort is critical to providing effective dental care. The aim of this study was to compare patient and operator comfort between two devices with the function of periopolishing and piezoelectric scaler during guided biofilm therapy (GBT) sessions. A randomized controlled trial was conducted involving 20 patients and operators. Primary outcomes, including pain, sensitivity, and operator comfort, were assessed using a visual analog scale (VAS), while periodontal indices served as secondary outcomes. The results showed comparable levels of patient and operator comfort between the two devices, with higher airflow comfort reported for the Mectron Combi Touch and higher ultrasonic handpiece comfort showed for the EMS Prophylaxis Master. Both devices effectively reduced periodontal parameters without significant differences. These results indicate that both Mectron Combi Touch and EMS Prophylaxis Master offer viable options for efficient and patient-friendly periodontal treatment.
