Brief Summary

A study on the efficacy of systematic oral health education for the prevention of oral-related complications caused by radiotherapy for head and neck malignant tumors

Detailed Description

The goal of this clinical trial is to investigate the efficacy of systematic oral health education for oral-related complications in patients with head and neck malignant tumors who receive radiotherapy. The main question it aims to answer is:

the efficacy of systematic oral health education for the prevention oral-related complications caused by radiotherapy for head and neck malignant tumors

Participants will:

be given systematic oral health education or routine oral health education be evaluated to learn the efficacy of systematic oral health education for the prevention of oral-related complications caused by radiotherapy for head and neck malignant tumors Researchers will compare systematic oral health education group with routine oral health education group to see if systematic oral health education has good efficacy for the prevention of oral-related complications caused by radiotherapy for head and neck malignant tumors.

Primary Outcome Measures
NameTimeMethod
Oral mucositis1 week before radiotherapy; weekly during radiotherapy(until 7 weeks); 1, 3, 6, 12 months after the end of radiotherapy

Oral mucositis is assessed by trained physicians according to World Health Organization (WHO) oral toxicity Scale(grade 1-5); Higher grade indicates more severe symptoms

Secondary Outcome Measures
NameTimeMethod
Xerostomia1 week before radiotherapy; at the middle of radiotherapy(3 weeks after the start of radiotherapy); at the end of radiotherapy(the last radiation dose received, usually 6 or 6.5 weeks); 1, 3, 6, 12 months after the end of radiotherapy

Patients self-evaluated xerostomia according to Xerostomia questionnaire(score 0-100);Higher score indicates more severe symptoms

Quality of Life assessed by QLQ-H&N351 week before radiotherapy; at the middle of radiotherapy(3 weeks after the start of radiotherapy); at the end of radiotherapy(the last radiation dose received, usually 6 or 6.5 weeks); 1, 3, 6, 12 months after the end of radiotherapy

Quality of Life is assessed by QLQ-H\&N35(Head and neck cancer-related quality of life scale);transformed into 0-100 scales for different domains and symptoms;Higher scores represent worse quality of life

Number of teeth1 week before radiotherapy; at the middle of radiotherapy(3 weeks after the start of radiotherapy); at the end of radiotherapy(the last radiation dose received, usually 6 or 6.5 weeks); 1, 3, 6, 12 months after the end of radiotherapy

Number of teeth is assessed by trained physicians

Dysphagia1 week before radiotherapy; at the middle of radiotherapy(3 weeks after the start of radiotherapy); at the end of radiotherapy(the last radiation dose received, usually 6 or 6.5 weeks); 1, 3, 6, 12 months after the end of radiotherapy

Dysphagia is assessed by M.D.Anderson Dysphagia Inventory(score 20-100);Lower score indicates more severe symptoms

Quality of Life assessed by EORTC QLQ-C301 week before radiotherapy; at the middle of radiotherapy(3 weeks after the start of radiotherapy); at the end of radiotherapy(the last radiation dose received, usually 6 or 6.5 weeks); 1, 3, 6, 12 months after the end of radiotherapy

Quality of Life is assessed by EORTC QLQ-C30(European Organization for Research and Treatment of Cancer Quality of Life Questionnaire);transformed into 0-100 scales for different domains and symptoms;Higher domain scores represent better quality of life, while higher symptom scores represent worse quality of life

Periodontal pocket depth1 week before radiotherapy; at the middle of radiotherapy(3 weeks after the start of radiotherapy); at the end of radiotherapy(the last radiation dose received, usually 6 or 6.5 weeks); 1, 3, 6, 12 months after the end of radiotherapy

Periodontal pocket depth is assessed by trained physicians using standardized periodontal probes

Bleeding on probing1 week before radiotherapy; at the middle of radiotherapy(3 weeks after the start of radiotherapy); at the end of radiotherapy(the last radiation dose received, usually 6 or 6.5 weeks); 1, 3, 6, 12 months after the end of radiotherapy

Bleeding on probing is assessed by trained physicians using standardized periodontal probes

Plaque1 week before radiotherapy; at the middle of radiotherapy(3 weeks after the start of radiotherapy); at the end of radiotherapy(the last radiation dose received, usually 6 or 6.5 weeks); 1, 3, 6, 12 months after the end of radiotherapy

Plaque is assessed by trained physicians according to Turesky-Modified Quigley-Hein Plaque Index; higher scores represent more plaque

Adverse effectsup to 12 months

Assessed by Common Terminology Criteria for Adverse Events (CTCAE) 5.0 version(grade 1-5);Higher grade indicates more severe symptoms

Changes of oral flora1 week before radiotherapy; at the middle of radiotherapy(3 weeks after the start of radiotherapy); at the end of radiotherapy(the last radiation dose received, usually 6 or 6.5 weeks); 1, 3, 6, 12 months after the end of radiotherapy

The changes of oral flora in patients' salivary or oral swab measured by 16s rDNA technique
