Despite its prevalence, a standard definitive therapy to treat this condition has yet to be available. A novel treatment modality with pentoxifylline, tocopherol, and clodronate (PENTOCLO) was first reported in the literature in 2005. There has since been a steady rise in the number of studies exploring the efficacy of PENTOCLO in treating ORN in head and neck patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective:<\/jats:title>\n                    <jats:p>This article investigates the efficacy of PENTOCLO in treating ORN in head and neck cancer patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Evidence Review:<\/jats:title>\n                    <jats:p>PubMed, Scopus, Cochrane Library, and Medline were used to review articles on PENTOCLO use for head and neck ORN from 2005 to the present. Two reviewers independently screened titles and abstracts from 114 articles, and inclusion was based on pair consensus. The main inclusion criteria were human clinical studies using PENTOCLO for at least 6 months in treating ORN in head and neck cancer patients. The selected main outcomes to determine the efficacy of PENTOCLO therapy were wound healing status after treatment, reduction in the percentage of exposed bone, and symptom surveys post-PENTOCLO therapy. Eight studies were selected for final statistical analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Findings:<\/jats:title>\n                    <jats:p>The primary site of ORN in most studies was mandible (77%).
