Leukocyte and platelet-rich fibrin is known to contain high concentrations of growth factors and when associated with rhBMP-2, it may increase bone remodeling due to its osteoinductive property. The aim of this case is to report the outcome of surgical treatment of medication-related osteonecrosis of the jaw with prototype plate installation and the use of leukocyte and platelet-rich fibrin in association with rhBMP-2 in a 78-year-old female patient under therapy with alendronate. The present Studies describes that the combination of this treatment presented complete healing of osteonecrosis and represents a promising treatment option to be used for medication-related osteonecrosis of the jaw.

Objectives: To assess halitosis parameters using OralChroma™ and the correlation with salivary flow, oral hygiene index, radiation dose, and tongue-coating index among irradiated head and neck cancer patients compared to patients without cancer.

Materials And Methods: This cross-sectional study enrolled irradiated and non-irradiated patients divided into two groups. Hydrogen sulfide, methyl mercaptan, and dimethyl sulfide (DMS) levels were measured using a gas chromatograph, and sialometry was performed.

Oral halitosis is characterized by a foul, unpleasant breath that emanates from the oral cavity due to local or systemic conditions. Approximately 90% of offensive odors are caused by volatile sulfur compounds (VSCs). L-cysteine, used as a test solution to control bad breath, induces the formation of VSCs and serves as a preliminary rinse.

We present a case of osteoradionecrosis treated with leukocyte- and platelet-rich fibrin (LPRF) and surgery and followed up with clinical and tomographic investigations. A 65-year-old woman presented with pain in the posterior region of the right palate. Her medical history included cardiovascular disease and squamous cell carcinoma in the anterior region of the floor of the mouth that had been treated with intensity-modulated radiation therapy.

Background: Medication-related osteonecrosis of the jaw (MRONJ) is characterized by the development of bone necrosis in the jaws of patients receiving antiresorptive and/or antiangiogenic medications. No scientific reports have been published yet on bevacizumab-related osteonecrosis of the jaw (BeRONJ) when associated with dental implant placement and adjuvant ozone therapy.

Case Presentation: A 54-year-old female patient with a history of metastatic breast cancer and bevacizumab use presented with a dental infection.

Lesions associated with medication-related osteonecrosis of the jaws (MRONJ) are refractory to different treatment approaches. Hence, auxiliary approaches capable of improving patient outcomes should be explored. Leukocyte- and platelet-rich fibrin (LPRF) is a second-generation platelet concentrate (natural autologous fibrin matrix).

This paper describes two cases in which the use of leucocyte-rich and platelet-rich fibrin (LPRF) combined with bone resection did not result in complete tissue response in the treatment of medication-related osteonecrosis of the jaw (MRONJ). It has been recently described in patients receiving subcutaneous administration of RANK-inhibitors, such as Denosumab, and anti-angiogenic drugs, such as Bevacizumab, as observed in our cases. Due to promising results in recent studies, more patients will receive these medications in order to avoid skeletal complications due to metastatic bone disease and, therefore, this scenario has a potential to become a comparable challenge to the bisphosphonate- induced jaw necrosis in the area of Oral and Maxillofacial Surgery.
