Is the use of Pentoxifylline and Tocopherol effective in the treatment of Osteoradionecrosis of the jaws or for the treatment of medicationosteonecrosis of the jaw? An overview.

Purpose: The aim of the present study was to determine the methodological quality of systematic reviews that evaluated the effectiveness of pentoxifylline and tocopherol (PENTO) in the treatment of osteoradionecrosis of the jaw (ORNJ) and medication-related osteonecrosis of the jaw (MRONJ).
Methods: Searches were performed in Databases including PubMed, Scopus, LILACS, DARE, Cochrane Library, and SIGLE through OpenGrey until March 2024, were evaluated by two independent reviewers to answer the following question: Is the use of PENTO protocol effective in the treatment of ORNJ or for the treatment of MRONJ?
Results: A total of 256 articles were initially identified; however, following the use of appropriate inclusion and exclusion criteria, five systematic reviews were identified for detailed analysis. The final study sample comprised 588 patients: 397 patients with ORN and 197 patients with MRONJ who were treated with PENTO. The total recovery of individuals who used the PENTO protocol was 62,2 % for ORN and 100 % for MRONJ, with a follow-up period of 1 month to 10 years. The methodological quality of the studies was assessed using the AMSTAR 2 tool, in which four were of low quality and 1 moderate quality.
Conclusion: The treatment of ORN and MRONJ with pentoxifylline and tocopherol has shown good results in the studies presented, with a partial or total reduction in bone exposure. However, the low quality of the relevant reports highlights the need for primary and secondary studies with better methodological rigor to reduce bias and provide reassurance for this treatment option.
