Multifactor analysis of patients with oral sensory complaints in a case-control study / 中华医学杂志(英文版)

BACKGROUND@#There are an increasing number of patients with oral sensory complaints (OSCs) presenting to our dental clinic. For most dentists, it is difficult to distinguish burning mouth syndrome (BMS) from other oral mucosal diseases that may cause symptoms such as burning mouth. It is beneficial to effectively distinguish OSC patients to reduce misdiagnosis and eliminate burning symptoms as much as possible.@*METHODS@#Patients with oral burning sensations in the oral mucosal disease clinic were collected from the Peking University Hospital of Stomatology between September 1, 2014 and December 31, 2018. After excluding oral candidiasis, anemic stomatitis, dental material allergy, and other diseases from patients with oral sensory complaints, basic conditions such as gender, age, education level, job status, hyperglycemia, hypertension, hyperlipidemia, history of brain abnormalities, history of cervical spondylitis, history of thyroid disease, history of thyroid disease and insomnia were obtained. The BMS patients were compared with the control group. The t test and Chi-square test were used for statistical analysis to compare the clinical symptoms of these diseases and explore the risk factors for BMS.@*RESULTS@#In this case-control study, 395 patients (321 females and 74 males, mean age 55.26 ± 10.51 years) with oral sensory complaints and 391 healthy controls (281 females and 110 males, mean age 47.11 ± 13.10 years) were enrolled, among which, 8.4% (33/395) had oral candidiasis, 1.3% (5/395) had dental material allergy, 0.8% (3/395) had anemic stomatitis and 0.5% (2/395) had lichen planus. A total of 352 patients were eventually diagnosed with BMS. Anxiety and depression were more severe in BMS patients, as were the incidences of sleep disorders and brain abnormalities. Logistic regression analysis showed that age (odds ratio [OR] = 2.79, 95% confidence interval [CI]: 1.61-4.83, P < 0.001), total cholesterol level (OR = 2.92, 95% CI: 1.32-6.50, P = 0.009) and anxiety score (OR = 1.75, 95% CI: 1.01-2.77, P = 0.017) significantly increased the incidence of BMS. Patients with hyperglycemia (OR = 0.46, 95% CI: 0.23-0.89, P = 0.022), low body mass index (BMI: OR = 0.57, 95% CI: 0.34-0.93, P = 0.026) and low education level (OR = 3.43, 95% CI: 1.91-6.15, P < 0.001) were more likely to suffer from BMS.@*CONCLUSIONS@#Oral candidiasis, anemic stomatitis, and dental material allergy with burning symptoms should be excluded from patients with BMS. It is recommended to conduct a questionnaire survey (including anxiety and depression), blood cell analysis, and salivary fungus culture for all patients with an oral burning sensation. It is necessary to conduct a patch test on patients with oral burning sensations and metal restorations.

Clinical effect of functional chewing training in treatment of oral motor dysfunction in children with cerebral palsy: a prospective randomized controlled clinical trial / 中国当代儿科杂志

OBJECTIVE@#To study the effect of functional chewing training (FuCT) on masticatory function, the severity of tongue thrust, and the severity and frequency of drooling in children with cerebral palsy.@*METHODS@#A prospective study was performed for 48 children who were diagnosed with oral motor dysfunction from January 2019 to January 2020, and they were randomly divided into an FuCT group and an oral motor training group, with 24 children in each group. Both groups received FuCT or oral motor training for 12 weeks, and then they were evaluated in terms of the changes in the masticatory function, the severity of tongue thrust, and the severity and frequency of drooling.@*RESULTS@#There were no significant differences between the two groups in the masticatory function, the severity of tongue thrust, and the severity and frequency of drooling before treatment (P>0.05). After the 12-week training, the FuCT group showed significant improvements in the masticatory function and the severity of tongue thrust and drooling (P0.05), while the oral motor training group had no improvements in the masticatory function, the severity of tongue thrust, and the severity and frequency of drooling (P>0.05). After the 12-week training, the FuCT group had more significantly improvements in the severity of tongue thrust and the severity and frequency of drooling than the oral motor training group (P<0.05).@*CONCLUSIONS@#FuCT can effectively improve the masticatory function, the severity of tongue thrust, and the severity and frequency of drooling in children with cerebral palsy.

Study on the classification of periodontal phenotype based on crown forms and gingival characteristics / 实用口腔医学杂志

87 periodontally healthy young volunteers paticipated in the study.4 clinical parameters were measured:Gingival thickness (GT),gingival width (GW),papilla height (PH) and crown width/crown length ratio (CW/CL).Cluster analysis was employed to identify the periodontal phenotypes.As a result,the periodontal phenotype of maxillary anterior tooth was classified as thin fan type (Ⅰ,n =31),thick and wide type(Ⅲ,n =8) and intermediate type(Ⅱ,n =48) in Han Chinese.

Relationship between gingival thickness and the underlying bone thickness in maxillary anterior tooth area / 实用口腔医学杂志

Objective:To study the relationship between gingival thickness(GT)and the underlying alveolar bone thickness(BT)in maxillary anterior region and the distance from cemento-enamel junction(CEJ)to alveolar crest.Methods:30 young volunteers with healthy gingiva were included.GT was measured at 2mm below the CEJ,buccal BT were measured at 3 locations:2,4 and 6 mm below the alveolar crest respectively,the distance from CEJ to alveolar crest were measured by CBCT and clinical direct measure respectively. Results:The correlation coefficient (r)values between GT and BT at 2,4 and 6 mm below alveolar crest were 0.493,0.383 and 0.342 (P <0.001 )respectively,the r value between GT and the distance from CEJ to alveolar crest was -0.21 3(P <0.01 ).No statistically significant difference was observed between CBCT and clinical measurements(t =-0.521 ,P =0.603).Conclusion:There is positive correlation between GT and BT at 2,4 and 6 mm below alveolar crest and negative relation between GT and the distance from CEJ to alveolar crest.

A case-control study of burning mouth syndrome and symptoms of anxiety and depression / 中国心理卫生杂志

Objective:To evaluate the anxiety and depression symptoms of burning mouth syndrome (BMS), and to explore risk factors to BMS.Method:In this case-control study,147 patients with BMS and 140 sex-and age-matched healthy volunteers were recruited.Three questionnaires were used to collect information of psychical and mental condition.The Self-Rating Anxiety Scale (SAS)and Self-Rating Depression Scale (SDS)were applied to evaluate symptoms of anxiety and depression.The scores of SAS and SDS were statistically analyzed by t-test.The risk factors of BMS were statistically analyzed by Chi-square test and logistic regression analysis.Result:The scores of SAS and SDS were higher in the patients with BMS than in the controls [SAS:(44.4 ±9.9)vs. (35.7 ±6.2);SDS:(48.1 ±11.6)vs.(37.5 ±8.9)].The risk factors of BMS included ischemic stroke (OR =4.46,95%CI:1.87 -10.95),low level of education (OR =1.91,95%CI:1.04 -3.49),anxiety symptom (OR =8.12,95%CI:2.60 -25.37)and depression symptom (OR =2.57,95%CI:1.26 -5.27).Conclusion:BMS is a multi-factorial disease.It indicates that ischemic stroke,lower level of education,anxiety symptom and depression symptom are the risk factors of BMS.A positive association could be established between psychological alterations and BMS.According to these findings it can be assumed that mental factors should be taking into account in the etiologyof BMS.It should be advocated to treat BMS patients by psychotherapy.

Study on the relationship between metabolic syndrome and chronic kidney disease in 1027 patients of Han and Uyguer people / 中华流行病学杂志

Objective To investigate the relationship between metabolic syndrome and the chronic kidnev disease in both Han and Uyguer populations.Methods 1027 cases were enrolled during 2006-3 to 2007-1 from the First Affiliated Hospital,Xiniiang University.According to the identification of chronic kidnev disease(CKD)and minor renal dysfunction,these patients were divided into different groups. The correlation between the components of metabolic syndrome and CKD was examined.T test,Chi-square test and logistic regression were used.Results (1)CKD and mild CKD prevalence were 37.4%and 24.0% in all the cases.(2)The Ievel of age,low-density lipoprotein cholesterol,trigly-ceride,high-density lipoprotein cholesterol.uric acid in Han people were higher than those among Uyguer people while body mass index.systolic blood pressure and diastolic blood pressure were lower than those Uyguer people. (3)There were no significant differences found between Han and Uyguer people in different metabolic components.(4)In the group which had only one metabolic component disjunction,the diabetic group accounted for big proportion while in those patients with two or more metabolic component dislunction,hypertension and obesity were significantly high in Han people but diabetes plus obesity were seen in Uyguer people.(5)Diabetes,obesity,metabolic components,uric acid were independent factors associated with CKD and mild CKD.Conclusion There were close connection between metabolic syndrome and CKD found in Xinjiang area.
