Objective: Bisphosphonate-related osteonecrosis of the jaws is considered to be a rare but severe complication of bisphosphonate therapy. To understand this condition better, data collection is essential. Although the number of scientific papers about this subject is large, to date only a few multicenter reports have been published. Study design: We present a novel cloud-based data collection system for the evaluation of the risk factors of bisphosphonate-related osteonecrosis of the jaws. Web-based questionnaire and database have been set up and made available to voluntary researchers and clinicians in oral and maxillofacial surgery in Hungary and Slovakia. Results: To date, fifteen colleagues from eight maxillofacial units have joined the study. Data of 180 patients have been recorded. Collected data were statistically analysed and evaluated from an epidemiological point of view. Conclusions: Authors consider cloud-based multicenter data collection a useful tool that allows for real-time collaboration between users, facilitates fast data entry and analysis, and thus considerably contributes to widening our knowledge of bisphosphonate-related osteonecrosis of the jaws.

Absztrakt: Bevezetés: A multifaktoriális, nem teljesen tisztázott patomechanizmusú, gyógyszer okozta állcsontelhalás kezelése napjainkban is nagy kihívást jelent a maxillofacialis sebészek és fogorvosok, valamint az onkológiai és oszteológiai gyógyszert felíró kezelőorvosok számára. Célkitűzés: Közleményünkben célul tűztük ki, hogy az aktuális szakirodalom áttekintését követően bemutassuk a változásokat a gyógyszer okozta állcsontelhalások patogenezisének, rizikótényezőinek, klinikai megjelenési formáinak, illetve a megelőzési és az új terápiás lehetőségeknek a tekintetében. Az elérhető nemzetközi ajánlások összehasonlításán, a nem sebészi és a sebészi, valamint a stádiumspecifikus kezelési módok evidenciaalapú bemutatásán túl a különböző orvosi-fogorvosi diszciplinákat érintő specifikumok bemutatására is törekszünk. Módszer: Az elmúlt 5 évben – az egyre növekvő számú betegségorientált adatbázisnak köszönhetően – a szakirodalomban megnőtt a szisztematikus szakirodalmi áttekintések (systematic reviews), ajánlások és metaanalízisek száma; ezek áttekintését és összehasonlító elemzését végeztük el a kitűzött célok vonatkozásában. Eredmények: Az American Association of Oral and Maxillofacial Surgeons munkacsoportjának legutóbbi ajánlása óta eltelt 4 évben is számos új gyógyszerhatástani csoport került a klinikusok látókörébe mint osteonecrosist indukáló potenciális ágens, így a betegség nómenklatúrája tovább cizellálódott, a betegcsoportok tovább specifikálódtak. A rizikóbetegek köre kiszélesedett, új betegpopulációknak (reumatológiai-oszteológiai betegek, immunszupprimáltak, transzplantáltak, új onkológiai ’target’ [célzott] terápiában részesülők) kell a súlyos mellékhatás kialakulásával számolniuk. Következtetés: Noha a betegcsoport kezelésében számos kérdés továbbra is nyitva áll, a korábbi empirikus kezelési formák helyett egyre erősebb evidenciákon alapuló, egyénspecifikus, stádiumadaptált terápiás megoldások körvonalazódnak.

Management of this rare but serious side effect is a real challenge and requires a multidisciplinary approach. Aim: The aim of the authors was to take stock of our present knowledge about the pathogenesis, risk factors, clinical manifestations and the possibilities of prevention and treatment in the medication-related osteonecrosis of the jaws. In addition, the available international guidelines are compared and the evidence-based, stage-specific conservative and adjuvant therapeutic approaches are also reviewed, having regard to special aspects of medical and dental care. Method: In the last 5 years – due to the increasing number of disorder-oriented database – the number of available systematic reviews, recommendations and meta-analyses has escalated significantly which we reviewed and compared. Results: Since the last Position Paper published by the taskforce of the American Association of Oral and Maxillofacial Surgeons, novel pharmacological groups with the potential to induce osteonecrosis have come in the clinical scope, further elaborating the nomenclature of the disease and further specifying patient groups. The sphere of patients at risk has broadened and novel patient groups (rheumatologic-osteological, immunosuppressed, transplanted or oncological patients treated with monoclonal antibody, known as ’target therapy’) are expected to develop this serious side effect. Conclusion: Although a number of issues are still open regarding the treatment of the disorder, evidence-based, individualized, stage-adapted therapeutic approaches have replaced the previous empirical treatment.

Study design: We conducted a prospective cohort study comparing interobserver reliability of 2 different 3D scanning measurement methods following dermal filler therapy in oral cleft patients. Objective of the study: The objective of the study was to compare the interobserver reliability of 2 different assessment methods of 3D facial scan data. Methods: We studied 10 oral-cleft patients prospectively who underwent dermal filler therapy in the oral region by a single oral-surgeon using a modified injecting technique with 27 gauge 25 mm micro-cannula between 2021 and 2023. 3D facial scans were made before the treatment procedure and during follow-up visits and were used for analysis. The interbody fusion was scored on these 3D images using the 2 classification systems (Method 1, Method 2) by 3 experienced orthodontic specialists all of whom were blinded to clinical data and outcome. Results: Of the 2 classifications included in the current study, all classifications had a high interobserver agreement. Conclusion: The 2 assessment methods used in this study showed high interobserver reliability so we can conclude that, the applied methods may provide as a validation in the outcome of dermal filler therapy. However, we suggest that further refinements may be required to achieve a reliable and consistent assessment of 3D facial scan analysis after dermal filler therapy in oral cleft patients.
