The aim of this study was to assess the thickness of the roof of the glenoid fossa (RGF) in Korean adult population without symptoms of temporomandibular disorder (TMD) using cone-beam computed tomography (CBCT). Methods: CBCT Data from 111 Korean adult patients aged ≥25 years (55 males and 56 females) without signs and symptoms of TMD were analyzed retrospectively in this study. The thickness of the RGF was determined as the perpendicular distance between the 'glenoid fossa line' and 'middle cranial fossa line' on parasagittal and paracoronal reconstructions, respectively. The thickness of the RGF according to sex and age was analyzed using t-tests (p<0.05). Differences were also examined between the right and left sides, and between the paracoronal and parasagittal sides. Results: The mean thickness of the RGF in all subjects was 0.75±0.39 mm; there was no significant difference in thickness between male (0.78±0.36 mm) and female (0.72±0.30 mm). We found no correlation between age and the mean thickness of the RGF, when age was grouped by decade. However, when subjects were divided into >40 years and ≤40 years age groups, the thickness of the RGF was significantly different between the groups. Conclusions: We found that the thickness of the RGF did not differ by sex, but might be affected by aging. Further studies with larger numbers of subjects are needed to confirm the results of this study.

Oral candidiasis is the most common fungal infection in the oral cavity which is usually diagnosed from clinical findings. A retrospective study was conducted to identify risk factors for oral candidiasis and to characterize the demographic and clinical features of affected patients.Methods: Methods: From January 1, 2019 to December 31, 2019, it consisted of 90 oral candidiasis patients diagnosed based on clinical finding and treated with antifungal drugs. As a retrospective study of those people, surveys were conducted on sex, age, systemic disease, a use of dentures, complaints of dry mouth, smoking and alcohol consumption, culture on potato dextrose agar (PDA) medium, culture on chromogenic agar (CA) medium and a duration of antifungal treatment.Results: Results: Among 90 selected patients, the male and female ratio was 41:49. Overall, female had a higher infection rate than male in all age groups. In this study, oral candidiasis was not clearly susceptible to dry mouth, smoking or drinking, wearing dentures and association with systemic disease. Among 90 patients with oral candidiasis, 83 had colonies formed on PDA medium and 53 had colonies formed on CA medium. The duration of antifungal treatment was highest between 5 and 8 weeks. In addition, there was statistical significance between the culture results in CA medium and the duration of antifungal treatment.Conclusions: Conclusions: Generally, old age or infants, dry mouth, smoking, a use of dentures and endocrine abnormalities are risk factors to increase oral candidiasis; however, in this study, it was mainly found in the elderly aged 60 or older regardless of sex and the incidence of oral candidiasis was not obviously related with patients with dry mouth, smoking or drinking, denture wearers and endocrine abnormalities. Interestingly, when the fungi were cultured in CA medium, the duration of antifungal treatment was increased.

The masticatory muscle disorder is the most common problem that patients with temporomandibular disorder often complain. For such complaints, treatment is directed towards reducing hyperactivity of muscles or effects of the central nervous system. However, if nonspecific occlusal change or pain persists, it is necessary to consider that muscle weakness might be the cause of the persistence of temporomandibular disorder. Stabilization of occlusion and improvement of the pain symptoms were achieved in both cases through the chewing gum exercise. This exercise may enable masticatory movements done in normal function by using muscle engram and achieve reinforcement of the masticatory muscles with balanced, simultaneous contacts of the teeth. In addition, it may be a viable method for treating temporomandibular disorders that do not respond well to conventional mandibular stabilization therapies.

In this paper, we prove some common fixed point theorems of compatible mappings with the generalized contractive mappings in metric spaces and also give some examples to illustrate our main theorems.These results generalize the results of some authors.

This study was conducted to analyze the clinical characteristics and distribution of the tongue-related diagnoses in patients with tongue symptoms.Methods: Methods: The subjects were patients who visited Chosun University Dental Hospital with tongue symptoms from January 1, 2021, to December 31, 2021. We analyzed 491 patients (139 males and 352 females) with tongue-related diagnostic code names in the Korean Standard Classification of Disease (KCD) in the Electronic Medical Record (Dentopinformation Technology Co., Seoul, Korea).Results: Results: On analyzing the diagnoses of tongue diseases using the KCD, glossopyrosis (44.8%) and painful tongue (15.2%) showed high rates. Of the 491 patients, 139 (28.3%) were males and 352 (71.7%) were females, and the average age was 58.1 years. As for systemic diseases, there were many patients with diseases of the circulatory system (27.0%) and endocrine, nutritional, and metabolic diseases (13.7%). Tongue symptoms were discomfort in 58 patients, pain in 329 patients, paresthesia in 10 patients, burning sensations in 222 patients, dysgeusia in 25 patients, dryness in 110 patients, fissures in 57 patients, and other symptoms in 72 patients. Areas with tongue symptoms were the anterior area in 102 patients, the lateral area in 140 patients, the posterior area in 12 patients, the dorsal area in 140 patients, the ventral area in 42 patients, and which area in 126 patients overall. Patients with burning mouth syndrome and oral candidiasis had significantly more tongue symptoms.Conclusions: Conclusions: Patients with tongue symptoms exhibited a variety of tongue diseases. Tongue symptoms were more common in women over 50 years of age and were frequently seen in patients with burning mouth syndrome and oral candidiasis.
