Conditions

Bisphosphonate-Associated Osteonecrosis of the Jaw Bone Neoplasms

Interventions

This is an observational historical cohort study design with a cross-sectional approach. The objective of the study is to evaluate the incidence, risk factors, and clinical-tomographic staging of Medi
s first zoledronic acid infusion (within the study&apos
s reference period) until the date of the current clinical dental evaluation or the date of death recorded in the medical system

Eligibility

Inclusion criteria

Inclusion criteria: Pacientes oncológicos; de ambos os sexos; que iniciaram o ciclo terapêutico com ácido zoledrônico (Zometa®) no período compreendido entre janeiro de 2023 e dezembro de 2024, independentemente da continuidade da terapia em anos subsequentes

Exclusion criteria

Exclusion criteria: Patients who progressed to death; or who present severe systemic debility (as documented in the medical records) that prevents in-person participation

Design outcomes

Primary

MeasureTime frame
It is expected to early identify the incidence of Medication-Related Osteonecrosis of the Jaw (MRONJ) Stage 0 cases, verified by means of systematic cross-referencing between intraoral clinical examination and Computed Tomography imaging analysis guided by a structured template, based on the observation of the frequency (in percentage) of prodromal radiographic findings such as focal bone sclerosis, thickening of the lamina dura, and persistent alveolar socket post-extraction in patients who do not present frank mucosal bone exposure

Secondary

MeasureTime frame
It is expected to demonstrate the direct correlation between the absence of prophylactic oral adequacy and the exacerbation of maxillofacial bone toxicity, verified by means of medical records analysis associated with the active search for local risk factors (such as tooth extractions performed during medication use and the presence of periodontal disease), based on the statistical finding that the highest percentages (%) of progression to severe clinical stages of American Association of Oral and Maxillofacial Surgeons (MRONJ) (AAOMS Stages 1, 2, and 3) occurred in the sample of patients subjected to traumatic risk factors while under zoledronic acid therapy
