Introduction: Radiotherapy-Induced Xerostomia (RIX) is one of the most common adverse effects of Radiotherapy (RT) in the Head and Neck Cancer patients (HNC), and a major determinant of survivors' quality of life. The primary objective was to evaluate the reduction of patients’ xerostomia symptoms after the utilization of a sodium-hyaluronate mouthwash compared to a placebo solution. The secondary objectives were to evaluate the improvement of quality of life, and to evaluate the patients’ satisfaction. Methods: The protocol was approved by the ethical committee (Ref. 50053/19) and registered at ClinicalTrials.gov (ID: NCT05103124). The study was a double-blind randomized clinical trial (RCT) with a crossover design and was conducted the Fondazione Policlinico Universitario A. Gemelli, Rome Results: Thirty-two patients completed the study protocol. Lower values of the modified Xerostomia Questionnaire (XQ) were retrieved when comparing the baseline scores to the ones after treatment, when compared with placebo (Mann-Whitney U test = 0.01); higher values of patients’ satisfaction (Likert Scale) and modified XQ were retrieved for the sodium-hyaluronate mouthwash (Mann-Whitney U test = 0.001). Conclusions: This RCT highlight the advantages of treating RIX with the sodium-hyaluronate mouthwash, since it seems to be clinically effective in reducing its symptoms, without any reported adverse events.

Objectives: The aim of this systematic review was to estimate the osteoradionecrosis rate in patients with head and neck cancer due to teeth extraction performed before radiotherapy and to identify possible risk factors. Material and Methods: PRISMA protocol was used to evaluate and present the results. PubMed, Scopus and Web of Science were used as search engines: English full-length papers of clinical studies, in peer-reviewed journals, were investigated. Cumulative meta-analysis was performed with a random effects model (PROSPERO registration code: CRD42018079986). Results: Among 2,020 records screened, 8 were included in this review. Sixteen of 494 patients who underwent tooth extraction before radiotherapy developed osteoradionecrosis, with an osteoradionecrosis incidence of 2.2% (95% Confidence of Interval=0.6–3.9, p&nbsp

Objective The purpose of this study was to describe an unusual case of intraoral juvenile xanthogranuloma (JXG) and to perform a systematic review to investigate the available literature regarding oral JXGs. Study design We present a new case of oral JXG arising in a 36-year-old Italian woman and conducted a systematic literature review in PubMed, Web of Science and Scopus, according to the PRISMA guidelines. Results Our review of the English-language literature yielded 34 cases of oral JXG, which are included in our case report. Conclusions JXG is a non-Langerhans cell histiocytosis. Oral JXG has been reported, but it is a rare manifestation. Because of the rarity of oral lesions and possible variations in the clinical and histological presentation, the correct diagnosis can be challenging, requiring a careful clinical and histopathological evaluation with adjuvant immunohistochemical studies.

Background: This study aims to find a correlation between Candida spp. oral colonisation prior to radiotherapy (RT) and (i) the development of severe oral mucositis (OM) (grade 3/4) and (ii) early development of severe OM (EOM). Methods: The protocol was registered on ClinicalTrials.gov (ID: NCT04009161) and approved by the ethical committee of the ‘Fondazione Policlinico Universitario Gemelli IRCCS’ (22858/18). An oral swab was obtained before RT to assess the presence of Candida spp. Severe OM occurring before a dose of 40 Gy was defined as EOM. Results: No patient developed G4 OM, and only 36/152 patients (23.7%) developed G3 OM. Tumour site and lymphocytopenia were risk factors for severe OM (OR for tumour site: 1.29, 95% CI: 1–1.67, p = 0.05; OR for lymphocytopenia: 8.2, 95% CI: 1.2–55.8, p = 0.03). We found a correlation between Candida spp. and EOM (OR: 5.13; 95% CI: 1.23–21.4 p = 0.04). Patients with oral colonisation of Candida spp. developed severe OM at a mean dose of 38.3 Gy (range: 28–58; SD: 7.6), while negative patients did so at a mean dose of 45.6 Gy (range: 30–66; SD: 11.1). Conclusions: Candida spp. in the oral cavity appears to be a predictive factor of EOM.

To assess (i) the prevalence of oral colonization by Candida spp. in patients with psoriasis and (ii) the prevalence of oral lesions associated with Candida spp. in patients with psoriasis and identify the risk factors for oral lesions. A systematic review was conducted in accordance with PRISMA criteria. The PROSPERO registration code is CRD42019127178. PubMed, Scopus and Web of Science were used as search engines. Meta-analyses and trial sequential analyses were performed. Among the 5805 retrieved records, nine articles were included. Among 530 psoriatic patients, 255 patients had an oral Candida spp. colonisation with an odds ratio (OR) = 3.44 (95% CI:2.38-5.00). Among 490 psoriatic patients, 43 patients developed oral Candida spp. lesions with an OR = 5.31 (95% CI:1.04-27.23). Among the patients without the main predisposing factors for infections, psoriatic patients had a higher OR (3.48, 95% CI: 2.0-6.0) for Candida spp. colonization, but not for Candida spp. infection, when compared with healthy controls (p-value > 0.05). Meta-analysis showed a higher risk of Candida spp. colonisation in patients with psoriasis. Patients who received immunosuppressive therapies were also at higher risk of developing oral lesions. Further studies are needed to understand these associations.

Background: Saprochaete clavata infection is an emerging issue in immunosuppressed patients, causing fulminant fungaemia. The purpose of this systematic review of cases is to retrieve all cases of S. clavata infection and describe oral lesions as the first manifestation of S. clavata infection. Methods: We report the first case of intraoral S. clavata infection in Acute Myeloid Leukemia (AML) affected subject, presenting as multiple grayish rapidly growing ulcerated swellings, and provide a review of all published cases of infection caused by S. clavata, according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, conducted by searching SCOPUS, Medline, and CENTRAL databases. Only articles in English were considered. Individual patient data were analyzed to identify risk factors for S. clavata infection. Results: Seventeen of 68 retrieved articles were included in the review reporting data on 96 patients (mean age 51.8 years, 57 males and 38 females). Most cases were disseminated (86) with a 60.2% mortality rate. Ninety-five were hematological patients, with AML being the most common (57 cases). Conclusions:S. clavata infection in immunosuppressed patients has a poor prognosis: middle-age patients, male gender and Acute Myeloid Leukemia should be considered risk factors. In immunosuppressed patients, the clinical presentation can be particularly unusual, imposing difficult differential diagnosis, as in the reported case.

Objectives: To analyze psychological profiles, pain and oral symptoms in patients with oral lichen planus (OLP). Materials and methods: 300 patients with keratotic OLP (K-OLP; reticular, papular, plaque-like subtypes), 300 patients with predominant non-keratotic OLP (nK-OLP; erythematosus atrophic, erosive, ulcerative, bullous subtypes) and 300 controls were recruited in 15 universities. The number of oral sites involved and oral symptoms were recorded. The Numeric Rating Scale (NRS), Total Pain Rating Index (T-PRI), Hamilton Rating Scales for Depression and for Anxiety (HAM-D and HAM-A), Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) were administered. Results: The OLP patients, especially the nK-OLP, showed higher scores in the NRS, T-PRI, HAM-D, HAM-A and PSQI compared with the controls (p-value

Objective: The aim of this study was to evaluate the postoperative course in patients undergoing oral mucosal biopsies, considering clinical and patient’s perception variables potentially correlated to poor healing. Subjects and methods: Eighty patients underwent oral biopsies. All the variables connected with the surgery were recorded, and the harvested volume was calculated through image software (ImageJ, NIH, Betesda, USA). To evaluate the postoperative discomfort, the OHIP-14 and the numeric rating scale of pain (NRS) were administered at 6 h, 7 days and 21 days after biopsy. Results: Six hours after the biopsy, 22 (OHIP-14 ≥ 20) and 24 (NRS ≥ 4) patients experienced a troublesome or painful healing, respectively. A significant statistical correlation between poor healing and high scores of NRS and OHIP was detected (Pearson’s correlation test p < 0.05). Higher values of OHIP-14 were correlated to the type of lesion (OR = 1.165; p < 0.05), whereas high values of NRS were correlated to the use of systemic drugs (p < 0.05). No surgical variable had a significant statistical correlation with any of the outcomes. Conclusions: The clinical evaluation was correlated with the patient’s perception of pain and discomfort. This finding could be suggestive of the fact that wound healing can be reliably monitored with the help of these tools. Clinical relevance: Patient perception can be a predictor of the healing of biopsied tissues.

Objective The aim of this study was to systematically review the literature to determine: (a) the malignant transformation rate (TR) of oral lichen planus (OLP) and its risk factors; (b) whether or not oral lichenoid lesions (OLL) have a different malignant TR. Materials and methods PubMed, Scopus, and Web of Science were used as search engines: only observational, full-length, English language studies were investigated. PRISMA protocol was used to evaluate and present results. PROSPERO registration code is CRD42016048529. Results Among 7,429 records screened, only 21 were included in this review. Ninety-two of 6,559 patients developed oral squamous cell carcinoma, with an overall TR of 1.40% (1.37% for OLP and 2.43% for OLL), an annual TR of 0.20%. Female gender, red clinical forms, and tongue site seem to slightly increase the transformation risk. Conclusions This systematic review confirms that both OLP and OLL, the latter with a slightly higher TR, may be considered potentially malignant disorders and suggest that erosive type, female gender and tongue site should be considered as risk factors for OLP transformation. Major efforts should be done to establish strict clinical and histological criteria to diagnose OLP and to perform sounder methodological observational studies.

Simple Summary Teeth extractions before or after radiotherapy (RT) could be procedures at high risk for osteoradionecrosis (ORN) onset. This systematic review was performed to investigate the ORN incidence following teeth extractions during and after RT for head and neck (H&N) cancer and to evaluate any other possible risk factor. The results highlight how post-RT teeth extractions are a major risk factor for ORN onset (ORN incidence of 5.8%), especially in the mandible, with a diminishing trend in the last years. Abstract Teeth extractions before or after radiotherapy (RT) could be procedures at high risk for osteoradionecrosis (ORN) onset. This systematic review was performed to investigate the ORN incidence following teeth extractions during and after RT for head and neck (H&N) cancer and to evaluate any other possible risk factor. Methods: This systematic review was conducted according to PRISMA protocol, and the PROSPERO registration number was CRD42018079986. An electronic search was performed on the following search engines: PubMed, Scopus, and Web of Science. A cumulative meta-analysis was performed. Results: Two thousand two hundred and eighty-one records were screened, and nine were finally included. This systematic review revealed an ORN incidence of 5.8% (41 patients out of 462, 95% CI = 2.3–9.4); 3 ORN developed in the maxilla. No other clinical risk factors were detected. Conclusion: Post-RT teeth extractions represent a major risk factor for ORN development, especially in the mandible, with a diminishing trend in the last years. Further research on other possible risk factors might improve this evidence.

Aim Due to its potential to influence systemic inflammation and oxidative stress, and to predispose to bacterial infections, sleep duration could potentially be a risk factor for periodontitis. The aim of this cross-sectional study was to evaluate if there was in 2012 an association between periodontitis and sleep duration in a representative sample of the South Korean population. Materials and Methods A total of 5812 subjects representative of 39.4 million of adults were examined. Multivariate logistic regressions were applied controlling for age, gender, education, smoking status, alcoholism and consumption frequency of coffee, tea, chocolate and red wine. Results Compared to the group sleeping ≤5 h/day, the adjusted odds ratios for periodontitis prevalence defined as Community Periodontal Index (CPI) = 4 were OR = 2.46 (95% CI: 1.20–5.06) in the 6 h/day sleepers group, OR = 2.66 (95% CI: 1.35–5.25) in the 7 h/day sleepers group, OR = 2.29 (95% CI: 1.13–4.63) in the 8 h/day sleepers group and OR = 4.27 (95% CI: 1.83–9.97) in the ≥9 h/day sleepers group. The association has shown to be highlighted in middle-aged people, females, non-smokers, lower educated, with lower lead and higher cadmium blood levels and with higher carotene dietary intake ones and to be partially mediated by lipid profile alterations, diabetes, serum Vitamin D levels and WBC count. Conclusions A novel, direct and independent association between sleep duration and the prevalence of periodontitis was found. However, it needs to be investigated how the factors influencing the sleep duration affect this association.
