Introduction: Geographic tongue and fissured tongue involve the most prevalent developmental tongue disorders, which allergy can be mentioned as one of its causes. Allergy is normally accompanied with different abnormalities such as mouth breathing and lymphoid hyperplasia. The purpose of this study was to assess the simultaneous occurrence of the head and neck lymphadenopathy and mouth breathing with geographic and fissured tongue. Methods: This case control study was conducted on 190 patients referring to oral medicine department of Yazd dental school who were systemically healthy without sinusitis, taking no medication within the last month, or having any source of dental infection. The study participants were chosen via convenience sampling divided into two groups including geographic or fissured tongue patients and the control group. After filling out the consent form, all subjects were examined in regard with head and neck lymphadenopaty and mouth breathing. In order to compare the two groups, SPSS software (version, 17) was applied utilizing Chi-Square test. Results: In the case group, 67 subjects had head and neck lymphadenopathy. No significant difference was observed between the case and control group in presence of lymphadenopathy (P-Value= 0.317). Moreover, 18 subjects in the case group demonstrated mouth breathing. The study results revealed a significant difference between the case and control group in presence of mouth breathing (P-Value= 0.005). Conclusion: The study findings revealed that regarding the significant difference in occurrence of mouth breathing, the probable symptoms of allergy should be taken into account in these patients in order to provide a timely diagnosis and treatment via frequent follow-up of such predisposed patients.

Introduction: Diabetes is the most common metabolic disease, which can cause different lesions in the oral mucosa, among which Candidiasis can be mentioned as one of the most common types of these lesions especially in the uncontrolled diabetic patients. Therefore, the present study aimed to compare Candidia colony count in the saliva of controlled and uncontrolled diabetic patients.

Methods: This case control study was conducted on 40 controlled diabetic (HBA1C<7) and 40 uncontrolled diabetic (HBA1C>7) patients, who had the admission criteria for this study. Saliva samples were collected by spitting method and cultured on the special media to determine the colonization and Candida type in both groups. The study results were analyzed using T-test and spearman correlation tests.

Results: The mean of Candida colony number was 54.2±85.3 in the controlled group and 186.3±192.9 in the un-controlled group, between which a statistically significant difference was observed (P=0.0001). Moreover, no significant correlation was reported between HBA1C and Candida colony number in both controlled and uncontrolled groups (P= 0.31 in controlled group, and P= 0.555 in un-controlled group). In this study, the Candida colony number separated from saliva samples of the controlled group and males (P=0.042) was significantly lower than the control group (P=000).

Conclusions: The mean of Candida colony number in saliva samples of uncontrolled diabetic patients was reported higher compared to the controlled group. There was no significant correlation between HBA1C levels and Candida colonization.
