Gingival retraction is a critical pre-impression procedure in fixed prosthodontics, crucial for exposing tooth margins and ensuring accurate impressions for restorations like crowns and bridges. This study aimed to evaluate the absorptive capacity of different gingival retraction cords. Ninety samples each of Ultrapak (Ultradent, South Jordan, UT, USA) #00, braided cord, coreless thread, and monofilament thread (totaling 270 samples) were immersed in 0.9% NaCl, 10% aluminum chloride, and 12.7% ferrous sulfate solutions for 120, 300, and 1200 s. The liquid absorption capacity was measured using a gravimetric method, and the data were analyzed using an F-test, setting the significance threshold at < 0.05. The results revealed statistically significant differences in absorption, particularly for aluminum chloride and ferric sulfate ( < 0.001). Ultrapak demonstrated the highest absorption, followed by the coreless cotton thread, while the monofilament thread absorbed the least, especially at 1200 s. These findings indicate that Ultrapak's superior absorption could enhance moisture control during procedures, highlighting the importance of selecting an appropriate retraction cord for optimal clinical outcomes. Further research is needed to confirm these findings in a clinical setting.

Purpose: To examine the impact of placing plain and impregnated retraction cords for two different retraction times on the postoperative gingival margin level and periodontal health.
Materials And Methods: A total of 40 endodontically treated mandibular first molars were selected and randomly allocated into four groups (n = 10/group); A: plain retraction cord for 10 min, B: plain retraction cord, 20 min, C: impregnated (25% aluminum chloride (AlCl) retraction cord, 10 min, D: impregnated retraction cord (25% AlCl), 20 min. Intraoral digital scans were acquired, and periodontal parameters (Plaque index [PI], Bleeding on probing [BOP], and probing depth [PD]) were assessed at baseline, 7 days, and 28 days after retraction.
A Retrospective Study of Stabilizing Bridges in Patients With Stages III and IV Periodontitis: Up to 35 Years of Clinical Audit.

Institute of Community Dentistry, University of Oslo, Oslo, Norway.
Background/aim: Studies on large cross-arch bridges in patients with severe periodontitis show that such bridges can stabilize the periodontal condition. However, it is not known if these bridges will reduce long-term tooth loss and what factors are important for their long-term survival. The aim of the study was to study all patients with Stages III/IV periodontitis who received cross-arch bridges for up 35 years in a private practice.

This study aims to characterise and assess the stability of an optimised lignocaine-adrenaline nanogel using central composite design (CCD). Compatibility studies were conducted using Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) and Ultraviolet-visible (UV-vis) spectroscopy. Eighteen lignocaine-adrenaline Nanoemulsion (LANE) formulations derived using CCD were characterised for particle size, polydispersity index (PDI), zeta potential and pH.

Objective: To evaluate the long-term status of incisors with canine-induced root resorption (CIRR).
Materials And Methods: Subjects with impacted maxillary canines (IMC) and persisting incisors with CIRR examined with cone beam computed tomography (CBCT), diagnosed ≥ 5 years earlier, were recalled. The resorption grade in the horizontal and vertical plane was assessed on CBCT images at baseline (T0) and follow-up (T1).

Article Synopsis
- This study compares the periodontal health effects of Cention N restorations and resin-modified glass ionomer cement (RM-GIC) in treating noncarious cervical lesions (NCCL), assessing plaque accumulation and gingival inflammation over time.
- It was a randomized controlled trial with 25 restorations for each of three methods, with evaluations conducted at various intervals up to 9 months.
- Results showed no significant differences between the two materials regarding plaque index and probing depth, but a small increase in these metrics over time was noted, highlighting the need for further research on long-term effects.
