Abstract
PURPOSE To provide evidence-based recommendations for prevention and management of osteoradionecrosis (ORN) of the jaw secondary to head and neck radiation therapy in patients with cancer. METHODS The International Society of Oral Oncology-Multinational Association for Supportive Care in Cancer (ISOO-MASCC) and ASCO convened a multidisciplinary Expert Panel to evaluate the evidence and formulate recommendations. PubMed, EMBASE, and Cochrane Library databases were searched for randomized controlled trials and observational studies, published between January 1, 2009, and December 1, 2023. The guideline also incorporated systematic reviews conducted by ISOO-MASCC, which included studies published from January 1, 1990, through December 31, 2008. RESULTS A total of 1,539 publications were initially identified. There were 487 duplicate publications, resulting in 1,052 studies screened by abstract, 104 screened by full text, and 80 included for systematic review evaluation. RECOMMENDATIONS Due to limitations of available evidence, the guideline relied on informal consensus for some recommendations. Recommendations that were deemed evidence-based with strong evidence by the Expert Panel were those pertaining to best practices in prevention of ORN and surgical management. No recommendation was possible for the utilization of leukocyte- and platelet-rich fibrin or photobiomodulation for prevention of ORN. The use of hyperbaric oxygen in prevention and management of ORN remains largely unjustified, with limited evidence to support its practice.Additional information is available at www.asco.org/head-neck-cancer-guidelines.

Abstract
OBJECTIVES This study aimed to investigate the incidence of osteonecrosis of the jawbones (ORN) after tooth extraction in patients undergoing low-dose rate brachytherapy (LDR-BT) and assess its safety. METHODS This study retrospectively analyzed 145 patients with tongue cancer treated at Hiroshima University Hospital from 2007 to 2021 with LDR-BT using 192Ir or 198Au alone, LDR-BT and external beam radiotherapy (EBRT) with or without chemotherapy, and LDR-BT with chemotherapy. Patients' mandible and maxilla were protected with spacers. Forty-seven patients underwent tooth extraction, and the incidence, site, and relationship of ORN with tooth extraction were recorded. A subgroup of 26 patients received additional EBRT to the neck after dissection for late cervical lymph node metastases. RESULTS Of 145 patients, six (4.1%) developed ORN on the same side of the mandible as LDR-BT, and EBRT was performed before and/or after LDR-BT on the sites where ORNs developed. Five of 47 (10.6%) patients who underwent tooth extraction after LDR-BT developed ORN. ORN incidence was 1.8% (2/109) in the LDR-BT and/or chemotherapy group and 11.1% (4/36) in the combination LDR-BT and EBRT and/or chemotherapy group for primary tongue cancer. Different irradiation methods (LDR-BT and/or chemotherapy and combination LDR-BT and EBRT and/or chemotherapy) and the presence or absence of tooth extraction showed significant differences (p = 0.0335 and p = 0.0139, respectively) with or without ORN. CONCLUSIONS Mandibular tooth extraction should be avoided on the side of LDR-BT in combined EBRT cases. However, tooth extraction is feasible using a spacer in LDR-BT and/or chemotherapy.

Dental Extractions Before Radiation Therapy and the Risk of Osteoradionecrosis in Patients With Head and Neck Cancer. JAMA Otolaryngol Head Neck Surg 2023; 149:1130-1139. [PMID: 37856115 PMCID: PMC10587826 DOI: 10.1001/jamaoto.2023.3429] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Accepted: 09/07/2023] [Indexed: 10/20/2023]
Abstract
Importance Patients with head and neck cancer undergo extraction of teeth with poor prognoses to minimize post-radiation therapy (RT) extractions, which are known to cause osteoradionecrosis (ORN). However, many patients are required to start RT before the extraction sites are completely healed. The role of pre-RT extractions in the development of ORN has been disputed in literature. Objective To determine whether the timing of pre-RT dental extractions is associated with ORN development in patients with head and neck cancer. Design, Setting, and Participants This retrospective cohort study was conducted at a single institution (Princess Margaret Cancer Centre, Toronto, Canada) between January 1, 2011, and January 1, 2018, and included 879 patients with head and neck cancer who underwent pre-RT dental extractions before curative RT of 45 Gy or greater. Patient demographic information and clinical characteristics (eg, primary cancer site, nodal involvement, chemotherapy, smoking status, dental pathology) were considered. Data analyses were performed from July to December 2022. Main outcomes and measures Timing (number of days) from dental extractions to RT start date and pre-RT extractions categorized as healed, minor bone spicules (MBS), or ORN. Results The study population consisted of 879 patients with a median (range) age of 62 (20-96) years, with 685 men (78%) and 194 women (22%). Of these, 847 (96.3%) healed from pre-RT dental extractions, 16 (1.8%) developed MBS, and 16 (1.8%) developed ORN. The median (range) time in number of days from pre-RT extraction(s) to start of RT was 9 (0-98) days in the healed cohort, 6 (3-23) days in the MBS cohort, and 6 (0-12) days in the ORN cohort. There was a large difference in the timing of pre-RT extractions between the healed and the MBS cohorts (mean 11.9 vs 7.4 days to radiation; difference 4.4; 95% CI, 1.5-7.3), and the healed and the ORN cohorts (mean 11.9 vs 7.1 days; difference 4.8 days; 95% CI, 2.6-7.1). Conclusion The findings of this retrospective cohort study suggest that there was an important association between the timing of pre-RT dental extractions and ORN when extractions occurred within 7 days of the RT start date. Despite this, ORN after pre-RT extractions is relatively rare. These findings indicate that patients with head and neck cancer who are to undergo RT should not delay treatment for extractions when it might compromise oncologic control.

Abstract
OBJECTIVES Assess the efficacy of biomechanical preparation using a reciprocating system followed by final irrigation protocols, then intracanal medication, on reducing endotoxins and cultivable bacteria of infected teeth in irradiated patients. MATERIALS AND METHODS Twenty-two infected single-rooted canals in patients submitted to head and neck radiotherapy were prepared by reciprocating motion and 2.5% NaOCl. Patients were randomly divided into two groups of 11 patients before the final irrigation protocol: apical positive pressure (APP) or passive ultrasonic activation (PUA). Both groups were treated in two sessions, using Ca(OH)2 as intracanal medication for 14 days. Root canal content sampling was performed after canal access (S1), after biomechanical preparation plus the irrigation protocol (S2), and after intracanal medication (S3). Chromogenic limulus amoebocyte lysate assay measured endotoxin levels (EU/mL), and bacterial load was determined by culture techniques (CFU/mL). RESULTS Treatment protocols reduced bacterial counts after S2 in both groups (p = 0.01). S3 differed from S1 (p = 0.01), but not from S2 (p = 0.4). Endotoxin levels were reduced in both groups after S2 (P = 0.03) and were lower in S3 than in S2, with significant differences in the APP group (p = 0.03). CONCLUSIONS Biomechanical preparation using a reciprocating system and 2.5% NaOCl in irradiated teeth, followed by the irrigation protocol (APP or PUA), demonstrated efficacy in reducing endodontic contaminants. Ca(OH)2 as intracanal medication should be performed in irradiated patients with infected root canals. CLINICAL RELEVANCE This clinical study demonstrated that endodontic treatment in irradiated patients is efficacious at reducing bacterial load and endotoxin levels.

Abstract
Osteoradionecrosis (ORN) often results in pathological fractures through progression. We aimed to identify the risk factors for pathological fracture in patients with mandibular ORN. Seventy-four patients with mandibular ORN were included in this retrospective study. We investigated various risk factors for pathological fracture in patients with mandibular ORN, including number of mandibular teeth with a poor prognosis each at initial evaluation before radiation therapy (RT) and when fracture occurred, and the proportion of antibiotic administration period in a follow-up duration after RT. The rate of occurrence of pathological fractures in patients with mandibular ORN was 25.7%. The median of duration between RT completion and fracture occurrence was 74.0 months. We found that pathological fracture was significantly associated with a larger number of mandibular teeth with a poor prognosis at initial evaluation before RT (P = 0.024) and when fracture occurred (P = 0.009). Especially, a larger number of mandibular teeth with P4 periodontitis, in other words severe periodontal status, was related to pathological fracture in both timings. The proportion of antibiotic administration period in a follow-up duration was also significant risk factor (P = 0.002). Multivariate analyses showed statistically significant associations between pathological fracture and a larger number of mandibular teeth with a poor prognosis when fracture occurred (hazard ratio 3.669). The patient with a larger number of mandibular teeth with P4 periodontitis may have a risk of not only occurrence of ORN but resulting in pathological fracture by accumulation of infection. Surgeons should consider extraction of those teeth regardless of before/after RT if necessary for infection control.

Effect of preradiation dental intervention on incidence of osteoradionecrosis in patients with head and neck cancer: A systematic review and meta-analysis. J Am Dent Assoc 2022; 153:931-942.e32. [PMID: 35985883 DOI: 10.1016/j.adaj.2022.06.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Revised: 05/23/2022] [Accepted: 06/07/2022] [Indexed: 11/27/2022]
Abstract
BACKGROUND The purpose of this systematic review was to examine whether dental intervention involving bone or soft-tissue manipulation preradiotherapy (pre-RT) is associated with lower rates of osteoradionecrosis of the jaw (ORNJ) in patients with head and neck cancer (HNC). TYPES OF STUDIES REVIEWED The authors included relevant studies from MEDLINE, Embase, and Cochrane Library, including observational studies published from 2007 through 2021 and involving adults who underwent dental intervention pre-RT for HNC. Authors assessed evidence certainty by using the Grading of Recommendations Assessment, Development, and Evaluation approach. Random-effects models were used to calculate pooled relative risk estimates and hazard ratios. When meta-analysis was not possible, study-level measures of association and narrative summaries of the evidence were reported. RESULTS Twenty-two studies were included. From the pooled, unadjusted analysis, patients undergoing pre-RT extractions may have a 55% increased risk of experiencing ORNJ (relative risk, 1.55; 95% CI, 0.85 to 2.86; very low certainty); the unadjusted pooled hazard ratio was 3.19 (95% CI, 0.99 to 10.31; very low certainty), corresponding to a possible increased hazard of developing ORNJ (very low certainty). Findings for other pre-RT procedures manipulating bone or tissue relied on limited, observational studies with low or very low certainty evidence. CONCLUSIONS Mostly very low certainty evidence suggests that patients with HNC who need pre-RT dental intervention may have an increased risk of developing ORNJ compared with those who do not. PRACTICAL IMPLICATIONS Maintaining optimal oral health may help reduce the need for urgent pre-RT dental treatment, potentially reducing ORNJ risk and minimizing delay of oncologic treatment in patients with HNC.

Abstract
This study identified the scientific literature comparing the influence of different times in which dental procedures were performed before the oncological treatments (radiotherapy and/or chemotherapy) on the risk of oral complications development. MEDLINE/PubMed and Embase databases were searched, and articles were selected by title, abstract and full-text assessment. The search identified 2,356 articles and three retrospective observational studies were included. Data were collected and analyzed according to the dental procedure, the time before oncological treatment, and oral complications. Risk of bias (ROBINS) and certainty of evidence (GRADE) were evaluated. Pairwise meta-analyses were performed from dental extractions (Exo) data according to the time which were performed and ORN development using a random-effect model (RR and 95 % CI, p < 0.05). meta-analyses showed a higher risk of ORN development in patients with Exo performed < 2 weeks before oncological treatment than in those who Exo was performed > 2 weeks ≤ 1 month before oncological therapy (RR 1.29; 95 % CI 1.12-1.48; p < 0.01). There was a higher prevalence of oral mucositis (OM) in patients who received periodontal treatment ≤ 3 weeks before oncological therapy than those who received dental procedures > 3 weeks ≤ 6 months before. Although the risk of bias ranged from serious to critical, with very low certainty of evidence, the findings suggest that dental extractions should be performed within > 2 weeks before oncological treatment to avoid ORN complications. More studies are needed to conclude the appropriate time to perform dental procedures to decrease other associated oral complications. (CRD42021272652).

Abstract
OBJECTIVES To determine the relation between the severity of periodontitis and osteonecrosis of the jaw (ONJ) occurrence among different cancer locations and estimate the effect of dental care on ONJ prevention in cancer patients. MATERIALS AND METHODS This population-based cross-sectional study was conducted through the Longitudinal Health Insurance Database, Taiwan. Patients with malignancies were collected and subdivided into groups according to their different cancer locations, the severity of periodontitis, and dental care. Multivariable logistic regression analysis was performed to assess the associations between ONJ and ONJ-related factors. RESULTS A total of 8,234 ONJ patients and 32,912 control patients were investigated. Lip, oral cavity, and pharynx malignancies had the highest ONJ risk among all cancer locations (OR from 3.07 to 9.56, P < 0.01). There is a linear relationship between different severities of periodontitis and ONJ. Patients with radiotherapy and severe periodontitis had the highest ONJ risk (adjusted OR, 9.56; 95% CI, 5.34-17.1). Patients with good dental care had a lower ONJ risk. CONCLUSIONS The periodontal condition and cancer location showed a significant impact on the risk of developing ONJ after adjusting for bisphosphonate use. Good dental care could decrease the risk of ONJ in cancer patients. The severity of periodontitis might be a target to predict the potency of ONJ. CLINICAL RELEVANCE Dentists must be vigilant about the increased risk of ONJ in cancer patients with periodontitis, especially in the head and neck cancer population. Good dental care is advised for cancer patients with severe periodontitis.

Serrano RV, Gomes TP, da Silva FM, Chambrone L, Marques MM, Palma LF. Autologous platelet concentrates in extraction sockets for the prevention of osteoradionecrosis: a systematic review of controlled clinical trials. Oral Maxillofac Surg 2022; 26:555-561. [PMID: 35048208 DOI: 10.1007/s10006-021-01030-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2021] [Accepted: 12/10/2021] [Indexed: 11/25/2022]
Abstract
This systematic review aimed to assess whether the use of autologous platelet concentrates immediately after tooth extraction would prevent ORN in patients treated with radiotherapy (RT) for head and neck cancer (HNC). MEDLINE, Embase, Ovid, Scopus, Web of Science, CENTRAL Cochrane, and OpenGrey databases were searched (up to, and including, June 2021) by two independent reviewers to identify studies, followed by further manual search. As inclusion and exclusion criteria for the studies, only controlled clinical trials (randomized or not) were considered. The risk of bias of each included study was assessed using the Cochrane Risk of Bias Tool. Of the 129 potentially eligible studies, only 2 were included, both randomized controlled clinical trials; however, one used platelet-rich plasma and another leukocyte- and platelet-rich fibrin. Overall, both autologous platelet concentrates had no effect on the outcome assessed. The use of autologous platelet concentrates seems not to be beneficial for ORN prevention following tooth extractions in HNC patients treated with RT; however, according to the available evidence, a reliable statement cannot be made.

Abstract
OBJECTIVE To examine how hospital-affiliated dentists assess risk and evaluate oral foci of infection in patients facing certain medical treatments, and whether the nature of upcoming medical treatment affects the choice of dental intervention. MATERIALS AND METHODS A survey comprising six clinical cases (50 teeth) was sent to hospital-affiliated dentists in Sweden. A treatment option for the affected tooth/teeth in each case was selected whether the patient was facing heart valve surgery, chemotherapy, radiation therapy, intravenous bisphosphonate treatment, solid organ transplantation or was diagnosed with endocarditis. RESULTS Consensus in choice of dental treatment was high in 62%, moderate in 32% and low in 6% of the assessments. High variability of choice of treatment was seen for eight teeth whereas the remaining 42 teeth often received the same therapy regardless of medical issue. Chemotherapy and radiotherapy were thought to entail the highest risk for oral infectious sequelae with a risk ranging from 1% to 100%. CONCLUSION Pre-medical dental evaluations and recommended treatments are often uniform with the exception of the management of asymptomatic root canal treated teeth with persisting apical radiolucency and heavily decayed molars. In many instances, dental diagnosis has a greater impact on choice of treatment than the underlying medical issue and associated implications thereof.

Abstract
Introduction: One of the most important complications of radiotherapy (RT) for head-and-neck cancer (HNC) is osteoradionecrosis (ORN) of the jaws, which mostly arises from tooth extractions. The ORN treatment still represents a great challenge; therefore, the prevention is of paramount importance. Thus, the present study aimed to evaluate retrospectively a perioperative systemic antibiotic therapy protocol for the prevention of ORN following tooth extraction in head-and-neck patients post-3D conformal RT. Materials and Methods: A retrospective medical record review was performed considering HNC patients submitted to RT in the period between 2008 and 2019. They necessarily received oral antibiotic therapy with Clindamycin 300 mg every 8 h for 10 days, with the first dose 3 days before the tooth extraction. Results: Forty-nine patients met the study criteria, with a total of 107 teeth extracted. Regarding the 47 patients who did not develop ORN, 103 tooth extractions were identified (96.3%). Only two patients developed ORN at two adjacent teeth sites (3.7%). Conclusion: The proposed perioperative systemic antibiotic therapy protocol seems to be efficient to prevent ORN following tooth extraction in postirradiated HNC patients.

Abstract
OBJECTIVES This study aimed to determine the relation between temporomandibular disorder (TMD) and ankylosing spondylitis (AS) bidirectionally and ascertain the important comorbidities for AS occurrence in TMD patients. MATERIALS AND METHODS We conducted this population-based cohort study through Longitudinal Health Insurance Database, Taiwan. Study 1 investigated the risk of TMD in AS patients. Study 2 assessed the risk of AS in TMD patients. RESULTS In total, 3204 AS patients and 12,816 age-matched and gender-matched comparisons were enrolled in study 1. The TMD incidence in the AS cohort was 2.88-fold higher when compared with the comparisons (1.54 vs. 0.53 per 10,000 person-years). After adjusting for age, gender, and comorbidity, the AS cohort had a 2.66-fold (95% CI = 1.79-3.97) increased risk of TMD occurrence (P < 0.0001). The second study recruited 4998 TMD patients and 19,991 age-matched and gender-matched comparisons. Both TMD and comparison cohorts showed similar AS risk (HR = 1.49, 95% CI = 0.91-2.43, P = 0.1108) in the adjusted model. Study 2 identified a 3.66-fold increased risk of AS occurrence in TMD patients with comorbidity, including parapsoriasis, rheumatoid arthritis, osteoporosis, Cushing's syndrome, and climacteric arthritis (P < 0.012). CONCLUSIONS AS appears to significantly impact the occurrence of TMD. TMD might play a synergic role in AS development. CLINICAL RELEVANCE Clinicians have to be vigilant about the increased risk of TMD in AS patients and take care of AS disease activity and prognosis. The symptoms and signs of TMD could be a predictor of AS in patients with the aforementioned comorbidities.

Int J Oral Maxillofac Surg 2020; 50:851-856.

Abstract
The purpose of this study was to compare complication rates at the mandibulotomy site between patients receiving preoperative radiotherapy (RT) and those receiving postoperative RT during treatment for oral and oropharyngeal cancer where the surgical procedure required a mandibular osteotomy to gain access to the tumour. Sixty-four consecutive patients treated during the period 2000-2015 were available for analysis. Their medical records were reviewed retrospectively. All patients were followed for at least 1year postoperatively. A subgroup of patients received RT on several occasions or long before the mandibulotomy, therefore the statistical comparisons focused on the two groups of patients receiving RT on one occasion and within 6 months prior to or following surgery. Seventeen patients presented a total of 29 complications, yielding an overall complication rate of 27%. Orocutaneous fistula was the most common complication. Patients who received RT preoperatively presented a higher complication rate (9/15; 60%) when compared to those who received RT postoperatively (2/31; 6.5%) (odds ratio 21.8, P<0.001). This study demonstrated fewer complications in the mandibulotomy area exposed to postoperative RT compared with preoperative RT. It is therefore suggested that, when possible, RT should be given postoperatively if combination treatment with RT and surgery, including a mandibulotomy, is planned.

Abstract
Background One of the most important complications of radiotherapy (RT) for head and neck cancer (HNC) is osteoradionecrosis (ORN) of the jaws, arising mainly from tooth extractions. Thus, the present study aimed to evaluate the efficacy of leukocyte- and platelet-rich fibrin (L-PRF) in preventing ORN following tooth extraction in post-irradiated HNC patients, as well as other postoperative complications.
Material and Methods 23 patients previously submitted to conventionally fractionated 3D-conformational RT for HNC underwent atraumatic tooth extractions with perioperative antibiotic therapy. Besides, they were randomly assigned to receive L-PRF clots to fill and cover the extraction sockets (n=11, Test Group) or not (n=12, Control Group). A visual analog scale was used to quantify postoperative pain on the 3rd and 7th days. For ORN diagnosis, patients were clinically assessed for up to 180 days. Other postoperative complications (edema, alveolitis, suture dehiscence, continuous bleeding, and oroantral communication) were also evaluated within this period.
Results No case of ORN or another surgical complication was observed and there were no differences in the postoperative pain scores between the groups on the 3rd and 7th days.
Conclusions L-PRF did not seem to provide any additional benefits than those achieved by the combination of the surgical and drug protocols used for tooth extractions in the post-irradiated HNC patients. Key words:Radiotherapy, osteoradionecrosis, tooth extraction, head and neck cancer.

Timing of dental extractions in patients undergoing radiotherapy and the incidence of osteoradionecrosis: a systematic review and meta-analysis. Br J Oral Maxillofac Surg 2020; 59:511-523.

Abstract
This systematic review aimed to examine whether the incidence of osteonecrosis differed between patients who have dental extractions before or after radiotherapy (RT). The reported incidence of osteoradionecrosis (ORN) of the jaws following RT to the head and neck varies widely in the literature. Currently, for patients with head and neck cancer there are no universally accepted guidelines on the optimal timing of dental surgery relative to RT to minimise incident ORN. A literature review was conducted using the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) criteria. A search of PubMed, EMBASE, Evidence-Based Medicine, and Web of Science databases targeted literature published up to and including 10 April 2020. Two independent reviewers assessed studies for eligibility against inclusion criteria. An assessment of bias was conducted for each of the included studies and relevant data extracted. A meta-analysis was undertaken using the statistical methods described. Twenty-four of 708 studies were included. They were heterogeneous and included a wide variation of RT methods, head and neck malignancies, and comorbidities. While some concluded that the incidence of ORN was dependent on the timing of dental extractions in relation to RT, with regard to the risk of its development, others reported additional factors such as age, comorbidities, extent of surgical resection, and dose and field of radiation, as more important predictors than timing. In many there was consistent lack of detail around the timing of dental procedures in relation to the delivery of RT. From 21 studies including 36,294 patients, of whom 14,389 had extractions before RT, the pooled incidence of ORN was 5.5% (95% CI: 2.1% to 10.1%). Significant heterogeneity was found in Cochran's Q-test (p<0.001) and Higgins I2=98.0%. From 21 studies including 37,805 patients, of whom 6030 had extractions after RT, the pooled incidence of ORN was 5.3% (95% CI: 2.9% to 8.2%). Significant heterogeneity was found in Cochran's Q-test (p<0.001) and Higgins I2=80.0%. There was no statistically significant difference between these two groups (random-effects model Q=0.12, p=0.73). Large, longitudinal studies with a priori-specified methods are needed to identify, recruit, and prospectively follow patients with head and neck cancer for the onset of ORN after dental surgery. This will allow clinical guidelines to be established to assist clinicians to plan treatment when extractions are indicated in patients undergoing RT to the head and neck.

Abstract
PURPOSE This study investigated the impact of dental prophylaxis on 5-fluorouracil (5-FU)-related oral mucositis (OM) according to the head and neck cancer (HNC) locations and treatment times. METHODS A total of 13,969 HNC participants, including 482 5-FU-related OM subjects and 13,487 comparisons were enrolled from the Longitudinal Health Insurance Database for Catastrophic Illness Patients of Taiwan between 2000 and 2008. All subjects were stratified into subgroups based on the times to perform chlorhexidine use, scaling, and fluoride application before 5-FU administration. The dental prophylaxis related to 5-FU-related OM was estimated by multiple logistic regression and represented with odds ratio (OR) and 95% confidence interval (CI). RESULTS Fluoride gel application and scaling significantly impacted on OM development (p < 0.001), and the joint effect of fluoride gel and scaling induced 5-FU-related OM (OR = 3.46, 95% CI = 2.39-5.01). The risk of OM was raised 2.25-fold as scaling within 3 weeks before 5-FU-related chemotherapy (95% CI = 1.81-2.81), and a 3.22-fold increased risk of OM while fluoride gel was applied during 5-FU-related treatment (95% CI = 1.46-7.13). CONCLUSION Dental prophylaxis significantly affected 5-FU-related OM in the HNC population. A short interval between dental scaling or fluoride application and 5-FU administration may be associated with higher prevalence of OM. Scaling simultaneously combined with chlorohexidine promoted 5-FU-related OM in specific HNC patients excluding the oral cancer and nasopharyngeal cancer population. Proper timing of the prophylactic dental treatments prior to 5-FU therapy could reduce the risk to develop 5-FU-related OM.
