Journal of Practical Stomatology.2017;33(1):117-119.

To compare the microleakage of fiber post and resin-core system fabricated by different methods.The roots of 36 recently extracted single-rooted mandibular premolars were undergone endodontic treatment.Fiber posts and Paracore flowable resin composite were used for fabricating post-core restorations.Microleakage was examined by dye penetration method.The microleakage value was significantly higher in Direct-Mold-Cement-Method group(4.94 ± 1.71) mm compared to Direct-Mold-Secondary-Cement-Method group(0.91 ±0.33) mm and Indirect-Mold-Secondary-Cement-Method group (0.87 ± 0.27) mm (P ＜ 0.05).

Journal of Practical Stomatology.2017;33(1):109-113. doi:10.3969/j.issn.1001-3733.2017.01.024

Objective:To evaluate the effectiveness of Xipayi Mouth Rinse in the treatment of halitosis.Methods:PubMed/MEDLINE,China National Knowledge Infrastructure (CNKI) (1979-2015) and Weipu Database for Chinese Technical Periodicals (1989-2013) were systemically searched.The methodological quality of the included trials was assessed based on the Jadad scale and the available data were analyzed with RevMan software (version 5.3).Results:8 studies involving 608 participants satisfied the minimum criteria for Meta-analysis.The evidence showed that the Organoleptic Score (OS) of Xipayi Mouth Rinse compared with placebo for treatment of halitosis was [WMD =-0.43,95％ CI (-0.57,-0.29)],plaque index (PLI) [WMD =-1.59,95％ CI (-1.67,-1.51)];the OS of Xipayi Mouth Rinse compared with western medicine [WMD =0.16,95％ CI (0.05,0.28)],PLI [WMD =0.10,95％ CI(0.03,0.18)];the total efficiency of Xipayi Mouth Rinse compared with normal saline was[RR:1.64,95％ CI(1.11,2.42)].Conclusion:The current clinical evidence showed that the effectiveness of Xipayi Mouth Rinse in the treatment of halitosis is higher than the Placebo,but lower than western medicine.

Journal of Practical Stomatology.2017;33(5):704-707. doi:10.3969/j.issn.1001-3733.2017.05.029

Patients underwent impacted mandibular wisdom tooth removal were randomly divided into 3 groups before operation.Patients in group A (n =41) were given pericoronal rinsing with 3 ％ H2O2 and saline before operation and irrigation once with povidone-iodine after tooth removal.Those in group B (n =43) were given irrigation with saline before and after tooth removal.47 patients in group C were given no irrigation as the controls.There was no significant difference in postoperative pain 3 days after operation among the 3 groups.Significant difference was found in postoperative pain 7 days after operation and mouth-opening 3 and 7 days after operation.There was significant difference in PoSSe scores among 3 groups but no difference between group A and B.It could be concluded that irrigation in pre-and post-operation can reduce the influence of teeth removal on life quality of the patients.

Significance of RGS16 protein expression in oral squamous cell carcinoma

Yi NING ; Liqin ZHAI ; Rui SUN

Journal of Practical Stomatology.2017;33(5):702-704. doi:10.3969/j.issn.1001-3733.2017.05.028

RGS16 protein expression in 84 cases of oral squamous cell carcinoma(OSCC) was examined by immunohistochemical staining method.RGS16 protein expression was positive in 78 out of the 84 cases.The expression was associated with the clinical stage of OSCC(P ＜ 0.05),but not with patient's age,gender,degree of differentiation and lymph node metastasis(P ＞ 0.05).

The effects of activator treatment on the hard and soft tissue profile of different skeletal patterns

Yanxiao ZHANG ; Ying CHEN ; Qing XU

Journal of Practical Stomatology.2017;33(5):689-694. doi:10.3969/j.issn.1001-3733.2017.05.025

Objective:To evaluate skeletal,dentoalveolar and soft tissue profile changes by activator therapy in patients with different skeletal patterns of Class Ⅱ1 malocclusions.Methods:22 subjects(10 girls,12 boys,mean age 11.5 ±0.67 years) in the mixed or early permanent dentition,were included and divided into low angle(n =15) and average angle(n =7) groups on the basis of skeletal pattern.All patients were treated with a traditional activator.The skeletal,dentoalveolar and soft tissue profile changes were compared on lateral cephalograms before and after treatment.Statistical analysis was performed with t-test of SPSS 13.0 at a level of significance of P ＜ 0.05.Results:Activator treatment in these growing patients resulted in a correction of the skeletal Class Ⅱ relationship (decrease of ANB,Wits and NA-Pg),an advancement of the mandibular structures(increase of Co-Pg and L1-APg),and changes of the teeth(increase of L6-MP).The changes of Wits,NA-Pg and L1-APg value of low and average angle groups were 1.34° ± 1.82 ° and 3.50 ° ± 1.77°,(3.06 ± 2.00) mm and (5.80 ± 3.17) mm,(-1.16-± 1.74) mm and (-2.83 ± 1.48) mm respectively(P ＜0.05).No statistical significance was found in the soft tissue profile changes whether intra-class or inter-group comparison.Conclusion:The activator appliance is effective in treating growing patients with mandibular deficiency,and mandibular reconstruction,in patients with average angle it is more effective than in those with low angle.

Xuexiao BAI ; Dan ZHAO ; Jie ZHANG

Journal of Practical Stomatology.2017;33(5):657-660. doi:10.3969/j.issn.1001-3733.2017.05.018

Objective:To analyze the incidence,treatment and resource consumption of primary oral squamous cell carcinoma (OSCC) in Beijing inhabitants.Methods:Consecutive cases of primary OSCC of Beijing inhabitants admitted to the Stomatology Hospital of Peking University between 2009-2013 were selected from the medical record department.A retrospective analysis was performed on the clinical data which including age,sex,sites,TNM stage,habits of smoking and drinking,treatment,fees,etc.Results:415 cases were included in this analysis.The male-to-female ratio was 1.2∶ 1.Tongue was the most common affected site(41.0％).The difference of the distribution of the affected sites between male and female patients was statistically significant(P ＜0.01).96.6％ patients were diagnosed above the age of 40 years with the median age of 64(56,73).The difference of the distribution of age between male and female patients was statistically significant(P ＜ 0.01).The patients with stage Ⅲ-Ⅳ accounted for 54.9％.With the development of T stage of the primary tumor,the average hospital fee,surgery fee and hospitolization time increased correspondingly.Conclusion:Late stage OSCC accounts for over half of all OSCC patients.The consumption of medical resources increases significantly with the development of tumor,thus more preventive measures are required.
