MRONJ
Patients diagnosed of medication-related osteonecrosis of the jaw (MRONJ). Treatment strategies vary depending on the stage of MRONJ and can be of different nature as: Conservative treatment Surgical treatment Adjuvant non-surgical treatment |
Procedure: Conservative treatment
Disinfectant mouth rinses, Antibiotic therapy, Antifungal therapy Procedure: Surgical treatment Superficial debridement, Complete removal of necrotic bone, Complete bone resection, When applicable revision and soft tissue coverage Procedure: Adjuvant non-surgical treatment Hyperbaric oxygen therapy Pentoxifylline and tocopherol Ozone therapy Low level laser therapy Pain relief Anti-inflammatory treatment Platelet rich plasma Parathyroid hormone and teriparatide Bone morphogenetic protein |
- Treatment outcome [ Time Frame: 6 months / 1 year ]
Compared to the baseline status of the patient's condition, the outcome will be evaluated as:
- Worsening of the osteonecrosis (e.g. size of the lesion increased)
- No change of the osteonecrosis
- Reduction of the osteonecrosis (e.g. size of the lesion decrease)
- Complete mucosa healing
- Pain perception [ Time Frame: 6 months / 1 year ]Numeric Rating Scale
- Staging of osteonecrosis [ Time Frame: 6 months / 1 year ]Staging of osteonecrosis according to the American Association of Oral and Maxillofacial Surgeons
- Site and size of the lesion [ Time Frame: 6 months / 1 year ]Site (single vs. multiple) and size of the lesion according to Weitzman et al.
