Abstract:
OBJECTIVETo investigate the positive rate, infection rate and bearing rate of salivary candida in patients with type 2 diabetes mellitus (DM), individuals with impaired glucose regulation (IGR) and individuals with normal glucose tolerance (NGT) and their predisposing factors.
METHODSQuestionnaire was given to 145 patients with DM, 142 individuals with IGR and 149 NGT individuals. Oral examination was carried out, and fasting plasma glucose (FPG) level and plasma glucose level of 2 hours post glucose-load (PG2h), resting salivary flow, salivary pH value were tested. Salivary candida was cultured.
RESULTSIn DM, IGR and NGT groups, the positive rates of salivary candida were 21.4% (31/145), 7.0% (10/142), 4.7% (7/149) respectively, the infection rates were 7.6% (11/145), 1.4% (2/142), 1.3% (2/149) respectively, and the bearing rates of salivary candida were 13.8% (20/145), 5.6% (8/142), 3.4% (5/149) respectively. The candida positive rate, candida infection rate in DM group were higher than those of IGR and NGT groups respectively (P < 0.05). There were no significant differences in the candida positive rate, infection rate and bearing rate between IGR and NGT groups (P > 0.05). Resting salivary flow in DM [(1.30 ± 1.20) ml/10 min] and IGR [(1.40 ± 1.17) ml/10 min]groups were lower than that in NGT group [(1.93 ± 1.66) ml/10 min], salivary pH values in DM (7.11 ± 0.56) and IGR (7.05 ± 0.48) groups were lower than that in NGT group (7.38 ± 0.48) (P < 0.05), while FPG value in DM [(7.68 ± 2.75) mmol/L] and IGR [(5.67 ± 0.73) mmol/L] groups were respectively higher tham that in NGT group [(4.99 ± 0.44) mmol/L], P < 0.05. The infection rate of salivary candida was influenced to some degree by age, FPG level and bearing denture (OR value = 1.106, 1.258, 3.166).
CONCLUSIONSThe patients with DM were more subjected to bearing or infection of candida than individuals with IGR and NGT. To control the plasma glucose level will help to decrease the positive rate and infection rate of oral candida.
