ABSTRACT
Objective:To assess the clinical efficacy of low-level laser therapy(LLLT)for the treatment of burning mouth syndrome(BMS)in elderly patients.Methods:As a randomized controlled study, 60 elderly BMS patients treated in the department of stomatology of Beijing Hospital from September 2018 to August 2021 were randomly divided into a laser group and a control group, including 7 man and 53 women, with an average age of(68.27±6.38)years.Patients in the laser group were treated with LLLT, and patients in the control group were treated with non-energy red light and oryzanol.The visual analogue scale and self-rating anxiety and depression scale were used to evaluate the two groups of patients.Results:After LLLT, the effectiveness rate of the laser group was 86.67%(26/30)on the 28th and 90th day, which was significantly higher than 63.33%(19/30)of the control group( χ2=4.356, P=0.037). When data for pre-treatment, the 28th day after treatment and the 90th day after treatment for the laser group were compared, results showed that after LLLT, pain symptoms of BMS patients were relieved and it lasted for some time, and anxiety and depression also improved, but there were episodes of relapse as time went on.Visual analogue scale and self-rating anxiety scores and depression scale scores of BMS patients for pre-treatment, the 28th and 90th days after treatment in the two groups were compared.Only self-rating anxiety scale scores of the laser group was lower than those of the control group on the 28th day, with statistical significance( t=2.622, P=0.011), indicating that LLLT could alleviate anxiety for BMS patients in the short term, but had no significant effect on patient depression.However, in the long term, LLLT had no significant effect on relieving anxiety and depression. Conclusions:LLLT has a certain effect on improving pain symptoms and anxiety in elderly BMS patients.
ABSTRACT
Objective To observe the clinical efficacy of photodynamic therapy on oral leukoplakia in elderly patients.Methods In this prospective study,fifteen elderly patients with oral leukoplakia were treated with 5 aminolevulinic acid-based photodynamic therapy(ALA PDT).After 2 hours of dressing,patients were irradiated using a 635nm semiconductor laser with the power density of 300mW/cm2.Each lesion was irradiated for 6 minutes with energy density of 100J/cm2.The curative effect was evaluated and the adverse reactions were recorded based on the observation of lesion changes.Results Of the 15 lesions in 15 patients,4 lesions were treated once,3 lesions were treated twice.And 6 lesions were cured after three treatments,and 2 patients were cured after four treatments.The average treatment frequency was (2.4 ± 1.1) treatment.The postoperative adverse reaction was pain.The average visual analogue scale was (2.2 ± 0.8) scores after operation,and the duration of pain was(2.6±1.1)days after operation.There was no recurrence for 3 to 9 months after operation.No abnormalities of oral sensation and function were found in patients.Conclusions ALA-PDT is an effective method for the treatment of oral leukoplakia in elderly patients.

ABSTRACT
Objective@#To investigate the prevalence of oral mucosal diseases (OMD) in patients with cerebrovascular disease.@*Methods@#A total of 182 patients with cerebrovascular disease and 166 controls were examined for OMD to compare the differences of prevalence rates.@*Results@#The prevalence of OMD in patients with cerebrovascular disease appeared higher than that in the control group. Oral candidiasis was most commonly seen (11.1%, 20/182), followed by fissured tongue (5.0%, 9/182), traumatic ulcer (2.8%, 5/182), herpes labialis (2.2%, 4/182), recurrent oral ulcer (1.6%, 3/182), chronic cheilitis (1.6%, 3/182) and oral leukokeratosis (1.6%, 3/182).@*Conclusion@#Patients with cerebrovascular diseases were susceptible to OMDs, especially to oral candidiasis that called for more attention.
ABSTRACT
Objective:To investigate the possibility for human papillomavirus (HPV)infection to be a predictable signal for the carcinogenesis of oral mucosa by comparing the prevalences of HPV in each stage of oral mucosal carcinogenesis and to compare the sensitivity differences of the two methods in de-tecting HPV infection in oral cavity.Methods:The hybrid capture (HC-Ⅱ)was used to detect infection of HPV in 255 samples taken from 1 2 cases of healthy oral mucosa,21 1 cases of patients with pathologi-cal diagnosis and 32 cases of patients with clinical diagnosis.The diagnosed cases included 8 cases of be-nign lesions of the oral mucosa,precancerous lesions [74 cases of oral leukoplakia (OLK)with hyper-plasia and 42 cases of OLK with oral epithelial dysplasia (OED)],91 cases of precancerous condition [oral lichen planus (OLP)]and 28 cases of oral squamous cell carcinoma (OSCC).And in situ hybri-dization (ISH)was used to detect infection of HPV in 33 cases of OSCC and 76 cases of OLK,including 30 cases of hyperplasia,1 5 cases of mild OED,1 5 cases of moderate OED and 1 6 cases of severe OED. Results:The prevalence of HPV in OLP samples was higher (1 2.1 2%,8/66 )than that of OLK (2.59%,3/1 1 6)(χ2 =4.666,P=0.031 )and OSCC(7.1 4%,2/28,χ2 =0.51 3,P=0.474).The prevalence of HPV in OSCC (7.1 4%,2/28)was higher than that of OLK (2.59%,3/1 1 6),and no significant difference was found.There was only one case of smoke spot and statistical analysis was not carried out.ISH was used to detect type 1 6/1 8 and type 31 /33 HPV DNA in 1 09 cases of oral mucosal lesions in paraffin sections and only one case of OSCC was HPV positive.Thirty-seven cases were detec-ted by HC-Ⅱ and ISH methods at the same time.The same negative results by the two methods were found in 94.6% samples (35/37).In the other two samples,one was OSCC with early infiltration and the other was OLK with hyperplasia,The HC-Ⅱ results were positive while the ISH results were nega-tive.The patients with OLP and HPV testing results were followed up and the average follow-up period was (36.2 ±1 0.5)months.It was found that three of them had a malignant transformation,and the ma-lignant transformation rate of HPV positive patients was 1 2.50% (1 /8),which was higher than that of HPV negative patients (3.45%,2/58),and the difference was not statistically significant,P=0.249. Conclusion:HC-Ⅱ assay was more sensitive in detecting HPV infection of oral mucosal lesions than ISH.The results of this study showed that there was insufficient evidence for taking HPV infection as a predictor of OLK carcinogenesis.Patients suffering from OLP were in a precancerous condition.The pre-valence of HPV in OLP patients of this study was higher than that in OLK and OSCC patients,suggesting that for some reason,OLP patients were susceptible to HPV.HPV testing can be considered as routine in patients with OLP,and HC-Ⅱassay was recommended.And patients with OLP and HPV positive should be followed up regularly.
ABSTRACT
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.
