Objectives: The current study aims to compare advanced-platelet-rich fibrin membrane (A-PRF) to connective tissue graft (CTG) using Han and Takei's approach.
Materials And Methods: The defective papilla was randomly allocated to either the control group (CTG) or to the experimental group (A-PRF). Papilla height (PH) and percent change in the gingival black triangle (GBT) area were recorded at 1, 3, 6, 9, and 12 months.
Results: Thirty-two deficient IDPs with an initial papilla presence index (PPI) of 2 or 3 were included. At 12 months, the papilla-fill significantly increased in both groups (p < 0.001) without a significant difference between the study groups (p = 0.637). A mean gain in IDP height of 2.25 mm (± 0.97) in the CTG group and 1.86 mm (± 0.7) in the A-PRF group were recorded with a nonsignificant difference. Gingival black triangle fill showed a 57.98% fill in the CTG and 54.65% fill in the A-PRF group, with no statistically significant difference between the groups (0.956). Regarding postoperative pain patients, the CTG group consumed significantly more analgesics than the A-PRF group (11.75 ± 3.51 and 8 ± 3.08, respectively, with p = 0.003).
Conclusion: Both CTG and A-PRF were found to be equally effective in increasing deficient IDP height with Han and Takei's surgical technique, with no significant difference. Within the current study's limitations, A-PRF seems to be a viable alternative to CTG in the treatment of GBTs.
Clinical Relevance: Multilayered A-PRF membrane can be used as a choice in the augmentation of receded papillae, using Han and Takei's technique.

Systemic lupus erythematosus (SLE) is an autoimmune disease whose pathogenesis is not fully understood to date. One of the suggested mechanisms for its development is NETosis, which involves the release of a specific network consisting of chromatin, proteins, and enzymes from neutrophils, stimulating the immune system. One of its markers is citrullinated histone H3 (H3Cit).

The cervical uncinate process is a unique structure of the cervical spine that undergoes significant changes in its morphological characteristics with age, and these changes may be related to osteoporosis. This study aimed to observe the distribution of cancellous bone in the cervical uncinate process and its morphological features using micro-computed tomography (Micro-CT) to gain a deeper understanding of the morphological characteristics of the uncinate microstructure. We performed Micro-CT scans on 31 sets of C3-C7 vertebrae, a total of 155 intact bone samples, and subsequently used the measurement software with the Micro-CT system to obtain parameters related to the cancellous bone of the uncinate process.

Post-traumatic osteoarthritis (PTOA) is a painful joint disease characterized by the degradation of bone, cartilage, and other connective tissues in the joint. PTOA is initiated by trauma to joint-stabilizing tissues, such as the anterior cruciate ligament, medial meniscus, or by intra-articular fractures. In humans, ~50% of joint injuries progress to PTOA, while the rest spontaneously resolve.

Articular malalignment and ulnocarpal impaction can progress to osteoarthritis in the wrist. This may be triggered by tears of the scapholunate ligament (rarely the lunotriquetral ligament) or the foveal lamina of the triangular fibrocartilage complex. In the pre-degenerative stages, radiographic findings are inconclusive, and symptoms may be absent or discrete.
