This study evaluates the accuracy and repeatability of craniofacial measurements with a 3D light scanner, specifically the EINSTAR scanner, in comparison to traditional caliper measurements for facial anthropometry. Eleven volunteers were assessed by two examiners, one experienced and one inexperienced, who performed direct caliper measurements and indirect measurements using the scanner. Results indicated minimal differences between caliper and scanner results, with overall high accuracy and reliability demonstrated by correlation coefficients. Despite the slightly longer scanning time, the benefits of 3D imaging, including detailed surface mapping and virtual modeling, justify its integration into clinical practice, particularly in maxillofacial surgery and craniofacial assessment. Craniofacial measurements obtained with the EINSTAR scanner showed excellent reliability and accuracy, which qualifies this method for clinical and scientific use.

Background: Periapical surgery is indicated for persistent periapical lesions that do not respond to conventional endodontic therapy, yet postoperative recovery is often hindered by pain, swelling, and delayed healing. Platelet-rich fibrin (PRF) membranes are autologous biomaterials with regenerative potential, capable of modulating inflammation and promoting tissue repair. Methods: This preliminary randomized controlled trial evaluated the effectiveness of PRF membranes in improving postoperative outcomes—specifically pain, swelling, and quality of life—after apicoectomy. Twenty patients requiring periapical surgery were randomly allocated to a PRF group (n = 10) or a control group (n = 10). In the PRF group, autologous PRF membranes were applied over the resected root-end and into the osteotomy cavity before flap closure. In the control group, no PRF membranes or any additional biomaterial were applied, apart from the standard root-end filling material (MTA), which was identically used in both groups as part of the routine apicoectomy protocol. All patients were blinded to allocation, and outcomes were assessed by an independent blinded evaluator. Facial swelling was quantified by 3D facial scanning, pain was recorded daily using a visual analog scale (VAS), and quality of life was evaluated with the PROMIS-29+2 Profile. Results: The PRF group showed significantly reduced swelling (mean volume difference, 7.12 cm³; p = 0.025), lower pain scores (VAS: 1.80 ± 1.22 vs. 3.80 ± 2.44; p = 0.034), and improved quality-of-life domains, including higher Physical Function (p = 0.032) and lower Sleep Disturbance (p = 0.008) scores. Conclusions: Within the limitations of this pilot study, PRF membranes enhanced postoperative recovery after periapical surgery by reducing swelling and pain while improving patient-reported outcomes. Larger multicenter trials are needed to confirm these preliminary findings.

Promising research results have been obtained on the tissue-regeneration properties of PRF (platelet-rich fibrin) in dentistry and maxillofacial surgery. PRF presumably promotes healing and accelerates ossification. In this case report, the patient had a history of Gorlin–Goltz syndrome, also called nevoid basal cell carcinoma syndrome, an autosomal dominant neurocutaneous disease that was known for many years. As a consequence, cysts were detected in both the mandible and maxilla. We performed decompression on this 37-year-old patient, followed by a cystectomy on an extensive lesion in the right angle of the mandible. One cyst from each side of the body mandible and one from the maxilla were completely enucleated, as determined using an intraoral exploration. The resulting bone defect was filled with a composite graft composed of a mixture of A-PRF and a serum albumin-coated bone allograft (BoneAlbumin). The wound was then covered with a PRF membrane. The surgical sites were closed per primam. The postoperative period was uneventful. Biopsies were performed after three and six months of healing for histological micromorphometry analyses. Dental implants were placed at the sampling site. Three months after the implantation, the ossified implants were fitted with superstructures. To date, no complications have appeared with the bone augmentation. The authors interpret from the findings that the combination of A-PRF and BoneAlbumin can be validated as a prosperous bone substitute. It can be safely implanted after a 3-month ossification period.

A PRF (Platelet Rich Fibrin) előállításának módszerét 2000-ben dolgozták ki, a trombocyta koncentrátumok második generációjához tartozik. Számos klinikai vizsgálat igazolta hatékonyságát, kombinálva különböző csontpótló anyagokkal.Elkészítéséhez a páciens saját vérét, alvadásgátló hozzáadása nélkül a kidolgozott protokoll szerint centrifugálják. A fo- lyamateredményeként leukocytákban és trombocytákban gazdag fibrin-alvadék nyerhető, mely extracelluláris mátrixként szolgál. A fehérvérsejtek és vérlemezkék növekedési faktorai lassan (2–3 hét) szabadulnak fel, így kedvezően befolyásolják a sebgyógyulást. A szerzők áttekintik a főbb irodalmi adatokat, és beszámolnak a PRF fogászati, dentoalveoláris és maxilofaciális sebészeti alkalmazásának lehetőségeiről (implantológia, csontpótlás, dentoalveoláris sebészet, parodontológia, arcüregzárás, sinus elevatio, osteonecrosis, endodontia).
