The guide drafted has the function of assisting health professionals involved in the oral care of patients with cancer, enabling the prevention or treatment of oral complications stemming from oncological treatment.

Purpose This study was conducted to review the literature regarding the types of cone-beam computed tomography (CBCT) artifacts around dental implants and the factors that influence their formation. Materials and Methods A search strategy was carried out in the PubMed, Embase, and Scopus databases to identify published between 2010 and 2020, and 9 studies were selected. The implants included 306 titanium, titanium-zirconium, and zirconia implants, as well as 5 titanium cylinders. Results The artifacts around the implants were the beam-hardening artifact, the streaking artifact, and band-like radiolucent areas. Some factors that influenced the formation of artifacts were the implant material, bone type, evaluated regions, distance, type of CBCT, field of view (FOV) size, milliamperage, peak kilovoltage (kVp), and voxel size. The beam-hardening artifact was the most widely reported, and it was minimized in protocols with a smaller FOV, larger voxels, and higher kVp. Conclusion The risk and benefit of these protocols in individuals with dental implants must be considered, and clinical examinations and complementary radiographs play an essential role in implantology.

Background To evaluate the impact of oral health on the quality of life (QOL) of individuals undergoing cancer treatment at the time of diagnosis of medication-related osteonecrosis of the jaw (MRONJ). Material and Methods The present cross-sectional study analyzed patients with MRONJ from 2013 to 2019. The collected data included demographic data, base disease, medications associated with MRONJ, route of administration and time of use, signs, symptoms, and tomographic features of acute MRONJ, staging according to American Association of Oral and maxillofacial Surgeons position paper 2014 (AAOMS), type of dental treatment performed, outcome, and the responses to the Oral Health Impact Profile questionnaire (OHIP-14). Statistical analysis was performed using the Tukey test to study the association between oral condition and the QOL. A p-value of less than 0.05 was considered statistically significant. Results The sample consisted of 16 medical records of patients with MRONJ. Psychological discomfort showed alarmingly significant results ( p < 0.001) with strong negative impact on the QOL of the patients. Functional limitation was the least affected dimension ( p = 0.747). The other dimensions did not show statistically significant results. Conclusions MRONJ compromises oral health and negatively impacts the QOL, especially with respect to the psychological discomfort (worry and stress). The OHIP-14 questionnaire proved to be an effective tool in the assessment of this impact. Key words: Medication-related osteonecrosis of the jaw, quality of life, oral health, OHIP-14.

Objective: To report the case of a patient after cancer treatment and evaluate the impact of oral health on quality of life, through the Oral Health Impact Profile (OHIP-14) before, during, and after dental treatment. Methodology: A patient after antineoplastic treatment attended the clinic specialized. In all consultations, OHIP-14 was applied. Case report: A 68-year-old man diagnosed with keratinizing squamous cell carcinoma of the larynx (T3N0MX), undergoing chemotherapy and adjuvant radiotherapy (2878.2 Grays) and vertical partial laryngectomy surgery without ganglionic emptying. After CT, he complained of tooth loss and discomfort in the tongue after radiotherapy. Ex-drinker for 5 years, ex-smoker for 6 months, but alcoholic for> 10 years and smoker <50 years. Side effects of antineoplastic treatment included labial dryness, hyposalivation, dental fractures, residual roots, changes in swallowing, pain during mouth opening, and cervical movement. The results OHIP-14 was medium (17.85), weak (3.52), weak (2.84) and null impact of oral health on quality of life in the initial consultation, throughout the dental treatment, at the end of dental treatment and 1 year and 2 months after dental treatment, respectively. There was a high impact on psychological discomfort (3.55), medium on psychological disability (1.6), and functional limitation (2.04), in 2015, 2017, and 2018, respectively. Conclusion: The performance of the dentist on the late oral effects of chemotherapy and radiotherapy had a positive impact on improving the quality of life after cancer treatment, with the help of the multidisciplinary team.
