Patients with kidney disorders are increasingly encountered in dental practice due to improvements in medical care leading to prolonged life expectancy. In order to provide appropriate and safe dental care for these patients it is important to have a working knowledge of renal disorders and related problems.
The aim of this study was to follow the long-term effects of radiation therapy of head and neck malignancies on oral yeast colonization, mucositis and salivary function. Included in this prospective study were 32 patients with intended radiation therapy of a malignancy of the head and neck. In all patients the salivary glands lay within the radiation field and the patients had at least five teeth. The first examination was performed after oral hygiene instruction and removal of questionable teeth before the start of radiotherapy. The following examinations were conducted after 3, 6, 9 and 12 months. Together with the quantitative determination of Candida colonization, three "mucositis" variables were assessed: (1) examiner-rated mucositis score (LENT/SOMA), (2) patient-rated mucositis symptoms, and (3) scintigraphic salivary excretion fraction. The maximum Candida colonization was found 6 months after radiation therapy and this declined to above normal values after 12 months. Salivary flow was at a minimum 6 months after radiation therapy and had slightly recovered by 12 months. Examiner-rated mucositis and patient-rated xerostomia showed no significant recovery after 6 or 12 months. The results of this study show slight recovery of the oral ecological system. Although the causal role of a single parameter is not clear, persistently elevated Candida colonization should be taken into account therapeutically.
OBJECTIVE: To measure the oral health status of southern Chinese nasopharyngeal carcinoma (NPC) survivors 1-4 years after radiotherapy. SUBJECTS AND METHODS: A total of 109 subjects participated in this cross-sectional study. Thirty-eight subjects were NPC survivors, 40 subjects were patients newly diagnosed with NPC and 31 were healthy subjects. Verified clinical examination techniques were used to assess limitation of jaw opening, the presence of mucositis, candidiasis, dental caries, periodontal disease [community periodontal index (CPI)] including attachment loss (ALoss) and prosthetic status/need. Differences among three groups were tested by chi-squared and Kruskal-Wallis tests. Relationships between selected clinical variables and radiation parameters were analysed using Spearman's rank correlation coefficients. RESULTS: The NPC survivors attended for dental treatment more frequently than the other groups (P < 0.01). NPC survivors had significant xerostomia (92%, P < 0.01), trismus (29%, P < 0.01), a higher prevalence of clinical candidiasis (24%, P < 0.01), a greater DMFT (16.4 +/- 7.0, P < 0.01), more decay/filled roots (2.1 +/- 2.9, P = 0.01) compared with new NPC patients and controls. No difference was found in CPI, ALoss, prosthetic status and need between groups. Dry mouth and tooth hypersensitivity were the most common oral problems perceived by the NPC survivors. CONCLUSION: Despite having regular dental follow-ups, oral health was compromised in NPC survivors 1-4 years postradiotherapy.
