The clinical effects of upper articular cavity injection with hyaluronate combined with Twin-block in the treatment of temporomandibular joint clicks / 实用口腔医学杂志

Objective: To observe the clinical effects of upper articular cavity injection with hyaluronate(HA) combined with Twinblock in the treatment of temporomandibular joint(TMJ) clicks. Methods: 60 patients with TMJ clicks were divided into 3 groups(n = 20) and were treated by articular cavity injection combined with Twin-block(group 1),Twin-block only(group 2) and injection of sodium hyaluronate gel(group 3) respectively. The effects were evaluated and compared before and after treatment by both doctors and patients. Results: The effective rate of group 1,2 and 3 was 95％,and 65％ respectively(P ＜ 0. 05). After treatment the TMJ clicks were almost dispeared in group 1,remitted in group 2 and slightly remitted in group 3. Conclusion: The articular cavity injection of HA combined with Twin-block is more effective in the treatment of TMJ clicks than Twin-block or articular cavity injection of HA.

Valproic Acid Modulates the Multipotency in Periodontal Ligament Stem Cells via p53-Mediated Cell Cycle

Human periodontal ligament stem cells (PDLSCs), a type of mesenchymal stem cell, are a promising source for dental regeneration and are identified in human periodontal ligaments from extracted third molars. Valproic acid (VPA) is a histone deacetylase inhibitor that has been used as a wide-spectrum antiepileptic drug and a medication for mood disorders. VPA has shown several effects on increasing the pluripotency of embryonic stem cells and controlling osteogenic differentiation, besides the prevention of seizures. However, its effect on proliferation and osteogenesis depends on the cell type and concentration. The aim of this study was to investigate the effects of cyclic and constant VPA treatment on PDLSCs. Proliferation and apoptosis of PDLSCs were determined with cyclic and constant VPA treatment. In cemento/ osteogenic differentiation, osteogenic markers decreased significantly after cyclic treatment with 0.5 mM VPA. In contrast, VPA enhanced osteogenic differentiation after constant treatment. With cyclic VPA treatment, p53 levels related to apoptotic pathway decreased to induce proliferation. These findings indicated that VPA has different roles in proliferation and differentiation of PDLSCs in vitro and in vivo via p53-related pathway.

Clinical study on the treatment of trigeminal neuralgia with radiofrequency thermal coagulation of peripheral branch of trigeminal nerve / 实用医学杂志

Objective To observe the clinical efficacy of multiple radiofrequency ablation therapy of trigeminal neuralgia. Methods 60 patients diagnoised as trigeminal neuralgia in our hospital were included from January 2014 to september 2014. The patients were randomly divided into two groups , 30 patients in treatment group and 30 patients in control group. Patients in treatment group were treated by multiple radiofrequency ablation therapy while patients in control group were treated by radiofrequency thermal coagulation therapy for trigeminal ganglion.Then comparing the curative effect of the two groups after the treatment. Results The VAS score showed insignificant difference between the two groups (P > 0.05). Conclusion The multiple radiofrequency ablation in the treatment of trigeminal neuralgia is effective clinically as fewer complications and shows higher security.

Clinical study of treating anterior disk displacement without reduction by conservative sequence method / 实用口腔医学杂志

Objective:To observe the clinical effects of conservative sequence method in the treatment of anterior disk displacement without reduction(ADDWR).Methods:300 patients with ADDWR were included.200 patients were treated by conservative sequence method (including upper articular cavity lavage with single needle + injection of sodium hyaluronate gel + physical therapy + gimmick reset + oral exercise) (group 1);the other 100 were treated by injection of sodium hyaluronate gel(group 2).Maximum mouth opening (MM0) and pain visual analogue scale(VAS) were measured and compared before and after treatment.Results:In group 1 the effective rate was 95.5％,before treatment MMO was (22.90 ± 3.18) mm,VAS (5.81 ± 0.32);3 months after treatment MMO (37.05 ± 4.43) mm,VAS (1.29 ± 0.19);6 months after treatment MMO (36.29 ± 4.08) mm,VAS (1.37 ± 0.22);12 months after treatment MMO (35.76 ±3.87) mm,VAS (1.52 ±0.28),respectively.In group 2,the effective rate was 78％,before treatment MMO was(23.12 ±4.02) mm,VAS (6.11 ±0.67);3 months after treatment MMO (36.11 ±4.02),VAS (1.89 ±0.21);6 months after treatment MMO (35.49 ±3.78),VAS (2.21 ±0.32);12 months after treatment MMO (31.53 ±4.87) mm,VAS (3.88 ±0.51)mm,respectively.By statistics,all the measurments showed statistical significance(P ＜ 0.05) between 2 groups.Conclusion:Conservative sequence method is more effective in the treatment of ADDWR.

Applied anatomy of zygoma and zygomatic arch / 中华医学美学美容杂志

Objective To deal with measurements of the relative convexity, to observe the morphological characteristics of zygoma and zygomatic arch, and to provide references for anthropology and medical science. Methods 108 dry skulls (62 male and 46 female) from Wuhan University Medical School were used, the zygomatic relative convexity of both sides were measured, and the morphological characteristics were observed in this study. Results Zygomatic process point lied in the middle of zygoma in horizontal direction, and situated 15-20 mm below the external middle 1/3 of infra-orbital margin. The zygomatic arch was anterolateral convexity, and face width in male was bigger than that in female. Conclusion The relative convexity and morphological characteristics of zygoma and zygomatic arch provide

Clinical analysis of fixation methods and sites in treatment of zygomatic complex fractures / 实用口腔医学杂志

Objetive:To analyze the fixation methods and sites in treatment of zygomatic complex fractures of 152 patients. Methods:The clinical data of 152 patients from 1990 to 2004 were investigated and analyzed, which focused on the changing trend of etiology and treatment methods. Results:Traffic accident was the primary reason for zygomatic complex fractures in China.152 patients received primary, timely reduction and fixation; Scalp coronal incision in combination with other incisions or alone was applied in 108 patients, the rest were treated by single local incisions. Rigid internal fixation was applied in 123 cases, and the single application of transosseous wire fixation was performed in 22 patients. 328 Ti plates were used. As to the fixation sites, 96 were applied at the zygomatic-frontal suture, 45 plates at zygomatic-maxillary suture and zygomatic crest, 92 plates at zygomatic-temporal suture, and 95 plates across the fracture line. Conclusion:Scalp coronal incision in combination with other incisions or alone can provide satisfactory outcome. Early, timely reduction and rigid internal fixation may result in better treatment results. The sites are focused at zygomatic-frontal suture, zygomatic-maxillary suture and zygomatic crest, zygomatic-temporal suture and the fracture line which restore the horizontal and vertical force route.
