Background: Radiotherapy and chemotherapy are frequently employed in head and neck cancer (HNC) patients causing significant side effects that impair life quality and prognosis. Photobiomodulation (PBM) has become a growing approach to managing such oral complications. Despite its proven efficacy and absence of contraindications, there is still a lack of universally accepted disease-specific PBM protocols.Objective: A narrative review was conducted to identify the current proposals relating to the use of PBM to treat complications of oncological treatments in HNC patients.Methods: An electronic search in PubMed and Scopus databases was performed with the following keywords: (“photobiomodulation” OR “PBM” OR “laser therapy” OR “LLLT” OR “laser”) AND (“head and neck cancer” OR “oral cancer”) AND (“mucositis” OR “oral mucositis” OR “dysgeusia” OR “oedema” OR “xerostomia” OR “dermatitis” OR “trismus”) until October 2021.Results: A total of 35 papers were included in the narrative review. Oral mucositis was the most studied complication, and advisable protocols are conceivable. Although there is a growing interest in PBM to manage of xerostomia, radiodermatitis, pain, and trismus, literature is still scarce to propose a universally feasible protocol.Conclusions: PBM therapy could significantly prevent or reduce the severity of many side effects related to cancer therapies. More research is needed to obtain recommendations over the preferable parameters.

BACKGROUND: Scoring systems have been widely used to evaluate the severity and activity of oral lichen planus (OLP). The aim of the present study was to compare two existing (one modified) scoring systems in the evaluation of OLP severity and correlation with pain. Three differently experienced raters were involved.\ud MATERIALS AND METHODS:\ud Consecutive patients with OLP were assessed for pain using the Visual Analogue Scale and examined at 10 intraoral sites before starting (T0) and three weeks after (T1) steroid therapy (Clobetasol). Three differently experienced raters evaluated photographs using two scoring systems designated White-Erosive-Atrophic (WEA) modified from an older WEA system (WEA-MOD) and Reticular-erythematous-Ulcerative (REU) systems. WEA-MOD Kendall's W and interclass correlation coefficient were calculated and correlation between REU/WEA-MOD and pain was calculated using Spearman coefficient.\ud RESULTS:\ud Most patients showed lesions on buccal mucosa (85-93,5%) and maxillary/mandibular gingivae (31,8-31,2%), predominantly reticular. At T0, Kendall-W coefficients of 0.89 and 0.74 were obtained for the REU and WEA respectively. At T1, Kendall-W coefficients of 0.83 and 0.58 were obtained for the REU and WEA respectively. Interclass correlation coefficient ranged from 0.87 to 0.90 for REU and from 0.58 to 0.87 for WEA. REU and WEA scores significantly decreased after therapy (p<0.000) as well as VAS (p<0.05). REU score showed correlation with VAS.\ud CONCLUSION:\ud All the raters achieved comparable measures using REU whereas WEA and WEA-MOD seem less reproducible. REU seems to correlate to disease activity and pain.existing (one modified) scoring systems in the evaluation of OLP severity and correlation with pain.

Treatments used in head and neck cancer greatly impact the physical, psychological and functional state of patients. Evaluation of quality of life has become an integral part of the treatment. This retrospective study evaluates features involved in changes in quality of life after major surgery for head and neck cancer within six months, according to self-reported outcomes. One hundred and thirty patients completed the University of Washington Quality of Life questionnaire one and six months after major surgery for head and neck cancer. A multivariate model was used to evaluate which diagnostic and therapeutic features were related to improvement of quality of life within a six-month period. Significant improvement in most features related to quality of life was already recognizable at six months. Patients submitted to more invasive treatment had the biggest improvement in quality of life between time-points, as well as those patients with bigger tumors. After major surgery, patients may undergo fast recovery, with overall quality of life likely to improve in the short-term. Clinicians must be aware of the importance of dealing with treatment-related issues immediately after surgery, with hopeful possibility of on-the-upgrade results.

Background and Objectives: Special Needs Patients (SNPs) and young non-collaborative children are more predisposed to develop oral pathologies due to poor collaboration and scarce access to dental treatment. The aim of this retrospective study was to analyze a sample of SNPs who received dental treatments either under general anesthesia (GA) or deep sedation (DS) over a period of 6 years. The number and type of procedure were analyzed. Materials and Methods: In total, 131 patients were included and mostly (>90%) treated under GA. Patients were either uncooperative and phobic (Group 1) or affected by mental, behavioral, and neurological disorders (Group 2), diseases of the nervous system (Group 3), or developmental anomalies (Group 4). Results: Patients in Group 2 required more invasive dental treatments than those in the other groups. Therapies were mainly preventive and restorative, except in Groups 3 and 4, where extractions were more frequent. The type of dental treatment significantly varied according to age and systemic condition. Only 5.3% of the patients needed a second intervention, despite only 17.6% of patients respecting the scheduled follow-up. Conclusions: Treatment under GA is effective, but the poor adherence to follow-ups and the risk of reintervention should be contrasted by improving the perception by parents/guardians of the importance of oral hygiene and periodic visits.
