Cancer Radiother 2023; 27:434-446. [PMID: 37268457 DOI: 10.1016/j.canrad.2023.01.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2022] [Revised: 01/02/2023] [Accepted: 01/31/2023] [Indexed: 06/04/2023]
Abstract
OBJECTIVE Efforts have been made to reduce epidemiological indicators of osteoradionecrosis in patients with head and neck cancer over recent years. This umbrella review aims to synthesize the information of the systematic reviews/meta-analyses investigating the effect of radiotherapy in patients with head and neck cancer on the frequency of osteoradionecrosis and to identify and analyze the gaps in current scientific literature. MATERIAL AND METHODS A systematic review of systematic reviews with and without meta-analysis of intervention studies was conducted. Qualitative analysis of the reviews and their quality evaluation were performed. RESULTS A total of 152 articles were obtained, and ten of them were selected for the final analysis, where six were systematic reviews and four were meta-analysis. According to the guide Assessing the Methodological Quality of Systematic Reviews (Amstar), eight articles included were of high quality and two of medium quality. These descriptive systematic reviews/meta-analyses included a total of 25 randomized clinical trials, showing that radiotherapy has positive effects on the frequency of osteoradionecrosis. Even though a reduction in the incidence of osteoradionecrosis was observed back in the history, in systematic reviews with meta-analysis, overall effect estimators were not significant. CONCLUSIONS Differential findings are not enough to demonstrate that there is a significant reduction in the frequency of osteoradionecrosis in patients with head and neck cancer treated by radiation. Possible explanations are related to factors such as the type of studies analyzed, indicator of irradiated complication considered, and specific variables included in the analysis. Many systematic reviews did not address publication bias and did identify gaps in knowledge that require further clarification.

Abstract
Osteoradionecrosis (ORN) and medication-related osteonecrosis of the jaw (MRONJ) are uncommon conditions, however when present they have a significant impact on a patient's quality of life and are notoriously difficult to treat. With medical advances resulting in improved survival rates and increased life expectancy, it is likely that general dental practitioners (GDPs) will more frequently be involved in the oral health management of patients at risk of both ORN and MRONJ. Though management of both diseases is beyond the scope of primary care dentistry, the GDP still has a key role in the patient's overall care. It is therefore important to have a good understanding of these conditions and their consequences for dental treatment in order to provide adequate patient support. Management requires a multidisciplinary approach to treatment and as part of this GDPs are integral in prevention, early recognition and maintenance of oral health following diagnosis. This article aims to refresh the reader's knowledge regarding MRONJ and ORN and support the GDP in managing this patient group.

Abstract
Introduction Patients are often keen to replace their missing teeth after radiotherapy for head and neck cancer (HNC), yet such replacement does not always take place.Aims This study aimed to investigate the influences on dentists' provision of dentures for patients treated with radiotherapy for HNC, including whether risk of osteoradionecrosis (ORN) is a factor influencing intention to provide dentures.Methods An online cross-sectional survey including a case scenario, self-reported behaviour and measures of factors (selected using the theoretical domains framework) that may affect dentists' decisions was completed by general dental practitioners (n = 150) and HNC multidisciplinary team dentists (n = 25) in England.Results Dentists' reluctance to provide dentures for HNC patients post-radiotherapy was often due to concerns about dry mouth and radiation caries rather than risk of ORN. Knowledge of guidelines and beliefs about consequences were independently associated with dentists' intention to replace missing teeth with dentures.Conclusion The likelihood of replacing missing teeth with dentures increased with awareness of clinical guidance on the use of dentures in HNC and that denture provision would have positive consequences that outweigh the costs.

Abstract
The Scientific Investigation Committee of the American Academy of Restorative Dentistry offers this review of the 2020 professional literature in restorative dentistry to inform busy dentists regarding noteworthy scientific and clinical progress over the past year. Each member of the committee brings discipline-specific expertise to this work to cover this broad topic. Specific subject areas addressed include prosthodontics; periodontics, alveolar bone, and peri-implant tissues; implant dentistry; dental materials and therapeutics; occlusion and temporomandibular disorders (TMDs); sleep-related breathing disorders; oral medicine and oral and maxillofacial surgery; and dental caries and cariology. The authors focused their efforts on reporting information likely to influence day-to-day dental treatment decisions with a keen eye on future trends in the profession. With the tremendous volume of dentistry and related literature being published today, this review cannot possibly be comprehensive. The purpose is to update interested readers and provide important resource material for those interested in pursuing greater detail. It remains our intent to assist colleagues in navigating the extensive volume of important information being published annually. It is our hope that readers find this work useful in successfully managing the dental patients they encounter.

Poor dental condition is a factor of imbalance of the nutritional status at the outset of management of head and neck cancer. Clin Oral Investig 2021; 26:1251-1259. [PMID: 34415435 DOI: 10.1007/s00784-021-04097-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Accepted: 07/20/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVES To determine whether deterioration of dental condition at the outset of management of head and neck cancer (HNC) is a nutritional risk and whether social deprivation is a cause of the poor dental condition observed in HNC patients. MATERIAL AND METHODS A nutritional assessment form (NAF) and the Nutrition Risk Index (NRI) were used to standardize the nutritional status of 108 patients at the outset of management of HNC (2017-2019). The NAF includes assessment of weight loss over the past 3 months, the amount and difficulty of food intake, and the presence of digestive disorders. Dental condition was assessed by the decayed, filled, and missing teeth acopre (DFM) index and the masticatory coefficient (MC). Dental status and social deprivation were correlated with the EPICES score. RESULTS A correlation was found between the extent of weight loss and dental condition. The MC was higher in absence of weight loss (46% vs. 27%, p = 0.03) and the DMF lower when weight loss was less than 5% (22.3 vs. 26.9 if > 5% loss of weight, p = 0.005). No correlation was found between dental status and nutritional status. Social deprivation was associated with a lower MC (26% vs. 50%, p < 0.001). CONCLUSION Dental condition is a risk factor for weight loss at the outset of management of HNC but is not a determinant of nutritional status. Clinical relevance Dental condition is no longer considered simply as a source of potential complications after radiotherapy but also as an important factor for nutritional status.

Abstract
Trismus is a post-radiotherapy complication that affects survivors of head and neck cancers. It is described as the reduction of mouth opening to less than 35 mm. The condition is a progressive process; hence early intervention is crucial to prevent further damage and weakness to the elevator muscles of the mandible. Here, we report a 40-year-old woman with known squamous cell carcinoma of the maxillary sinus in stage T3N0M0 who had undergone upper right partial maxillectomy with subsequent 33 fractions of radiotherapy (66 Gy; intensity-modulating radiotherapy). Five months post-radiotherapy, the patient showed interest in replacing her missing teeth to restore her oral functions and facial appearance. At her post-radiotherapy visit in the dental assessment clinic, she showed a mouth opening of 12 mm. The TheraBite® Jaw Motion Rehabilitation System™ and wooden tongue depressors were alternatively used for 6 weeks (4-5 stretches/day; each stretch held for 15 s). Mouth opening gradually increased to 20 mm. Consequently, a definitive obturator prosthesis was fabricated using computer-aided design and computer-aided manufacturing technologies with the 3Shape D900 model scanner. These were challenging and time-consuming steps, but acceptable facial appearance and mouth opening were restored for the patient. This case suggests that Therabite® Jaw Motion Rehabilitation SystemTM and wooden tongue depressors help to increase mouth opening significantly if used together and alternatively.

Abstract
BACKGROUND Teeth with a poor prognosis are often extracted prior to radiotherapy for head and neck cancer (HNC) in order to help prevent the need for dental treatment after radiotherapy that might in turn lead to the development of osteoradionecrosis. However, the details and impact of replacing missing teeth after radiotherapy for HNC have received little attention, especially from the patients' perspective. AIMS This study aimed to assess the use, satisfaction, and impact of denture use following radiotherapy for HNC. The study also sought to determine patients' satisfaction with information about replacing their missing teeth postradiotherapy. Finally, this study also aimed to assess interest in replacing missing teeth for those who had not done so. METHODS A structured, validated, and reliable questionnaire was sent to HNC patients who had received radiotherapy and had missing teeth at the time of discharge. In addition to demographic details and self-reported oral hygiene, the questionnaire included questions on use of (or interest in) dentures, satisfaction with dentures, satisfaction with information about replacing missing teeth, QoL as measured by two questions from the short version of WHOQoL-BREF, and oral functioning as measured by BCSQ-H&N. Demographic details and clinical details were extracted from the hospital records. RESULTS N = 80 (24%) returned a completed questionnaire. Participants had an average of 12 missing teeth (SD = 8.05). Most (n = 60, 75%) had not replaced their missing teeth. Of these, 35 (58%) were very or extremely interested in doing so. For HNC survivors who wore dentures, there was variable satisfaction and a number of side-effects of wearing dentures. Satisfaction with information about replacing missing teeth was low. There was no statistical difference in QoL or oral functioning between participants who wore dentures and participants who did not wear dentures. However, those with dentures reported fewer problems with carrying out daily routines as measured by the oral functioning tool. CONCLUSIONS QoL and oral functioning were similar regardless of denture use, highlighting reduced oral function in both those with and without dentures. In those who had not replaced their missing teeth, there was substantial interest in doing so and thus may be an unmet need. The dental team could offer HNC survivors more support after radiotherapy and following denture provision to improve information about denture use and increase satisfaction with dentures.

Denture use and dental risk factors associated developing osteoradionecrosis after head and neck radiotherapy: A retrospective analysis of hospital records. J Dent 2020; 99:103410.

Abstract
OBJECTIVES This study aimed to assess the association between denture use and occurrence of osteoradionecrosis (ORN) following radiotherapy for head and neck cancer (HNC). MATERIALS AND METHODS Medical records of 439 HNC patients treated with radiotherapy at Guy's & St Thomas' NHS Foundation Trust (London, UK) (2014-2019) who had missing teeth at the time of discharge were reviewed. Descriptive statistics were used to summarise the participant characteristics and outcome measures. Logistic regression analysis was used to identify factors associated with occurrence of ORN. RESULTS Patients had an average of 14 missing teeth and 39 % wore dentures. Twenty-two (5 %) developed ORN. Out of 22 who developed ORN, 11 (50 %) wore dentures. Of these, 5 patients developed ORN in areas contacted by dentures. Denture use was not significantly associated with the occurrence of ORN (OR = 1.94; 95%CI = 0.79-4.81; p-value = 0.150). Longer duration of radiotherapy (OR =1.03; 95%CI = 1.00-1.06; p-value= 0.048) and more missing teeth in the lower anterior area (OR = 1.11; 95%CI = 1.01-1.22; p-value = 0.024) were significantly associated with the development of ORN. CONCLUSIONS Within the limitations of this single-centre study in which few patients developed ORN, denture use may not be a risk factor for ORN following radiotherapy for HNC. This is likely to be the case if dentures are well-fitting and not causing sores or irritation. CLINICAL SIGNIFICANCE Replacement of the missing teeth with dentures in HNC patients post-radiotherapy may be a suitable choice for many HNC survivors. However, a powered study in a large cohort that includes clinical evaluation of dentures and the quality of fit alongside denture wearing experience would be useful to further assess the impact of denture use on the development of ORN.
