Aim: This study aimed to evaluate and compare the Platelet-rich fibrin (PRF) and Mineral trioxide aggregate (MTA) as a pulpotomy agent in primary molars.
Material And Methods: In this study, 50 primary molars from 50 healthy children aged 5-9 years requiring pulpotomy were randomly allocated into two groups. In PRF group, after coronal pulp removal and hemostasis, remaining pulp tissue was covered with PRF preparation. In the MTA group, the pulp stumps were covered with MTA (Pro Root MTA-Root Canal Repair Material, Dentsply International Inc.) paste obtained by mixing MTA powder with sterile water at a 3:1 powder to water ratio. All teeth were restored with reinforced zinc oxide eugenol base and glass - ionomer cement. Stainless steel crowns were given in both groups 24 h after treatment. Clinical evaluation was undertaken at 1, 3, and 6 months intervals whereas radiographic evaluation of the treated teeth was carried out at the interval of 6 months.
Results: By the end of 6 months, the overall success rate was 90% in PRF group and 92% in MTA Group. A statistically significant difference was observed between the groups at 6 months of follow-up (P < 0.05). The results were statistically nonsignificant between the groups (P > 0.05).
Conclusion: Radiographic and clinical outcome in PRF group could suggest it as an acceptable alternative in pulpotomy of primary teeth. PRF holds a promising future in the area of primary tooth vital pulp therapy.

Immunoassay detection of multiphosphorylated tau proteoforms as cerebrospinal fluid and plasma Alzheimer's disease biomarkers.
Nat Commun

Different forms of phosphorylated tau (p-tau) have shown strong potential as Alzheimer's disease (AD) biomarkers in both cerebrospinal fluid (CSF) and plasma. We hypothesized that p-tau proteoforms simultaneously phosphorylated at two different sites may have an increased diagnostic value compared with tau phosphorylated at a single site. Here, we developed two immunoassays detecting CSF and plasma tau simultaneously phosphorylated at both T181 and T231 (p-tau181&231) and at T217 and T231 (p-tau217&231).

Background: For a periodontist, treating recession is always a proud moment and a challenging task. The current trial aimed at comparing and clinically evaluating semilunar coronally repositioned flap (SCRF) and coronally advanced flap (CAF) procedures combined with platelet-rich fibrin (PRF) in the management of Miller's Class I recession defects.
Materials And Methods: Thirty-six recession sites were randomly divided into the CAF or SCRF groups.
The short term impact of radiofrequency ablative techniques and peripheral nerve block on thermoregulation in mouse models.

This study investigated the impact of multiple nerve block methods (local anesthesia, conventional radiofrequency thermocoagulation [CRF], and pulsed radiofrequency [PRF]) on thermoregulation. Focusing on hypothalamic function, the effects of local anesthesia, CRF, and PRF on central and peripheral temperatures were analyzed and compared. Our findings revealed that all three nerve block groups cause a decrease in central temperature, with the CRF group exhibiting the most pronounced effect.

Advanced platelet-rich fibrin (A-PRF) is produced by centrifuging the patient's blood in vacuum tubes for 14 min at 1500 rpm. The most important component of A-PRF is the platelets, which release growth factors from their ⍺-granules during the clotting process. This process is believed to be the main source of growth factors.

This study investigated the effect of platelet-rich fibrin (PRF) on bone healing around implants placed in elevated sinus cavities. Forty New Zealand albino rabbits were divided into eight groups, based on the time of sacrifice (14 or 40 days) and the material used: blood clot (control), hydroxyapatite (HA) from bovine bone, HA combined with PRF, and PRF alone. Each group consisted of five animals (n = 5).
