Objective: To compare the efficacy of fenestration decompression and curettage of jaw cyst in the treatment of jaw cyst and the changes of serum pain mediators after operation. Methods: The clinical data of 60 patients with jaw cyst who were treated in our hospital from January 2016 to August 2019 were analyzed retrospectively. According to the difference of treatment methods, they were divided into group A (curettage of jaw cyst, 28 cases) and group B (fenestration decompression, 32 cases). The operation indexes, postoperative recovery indexes, complications and changes of serum pain mediators in the two groups were observed. Results: Compared with group A, group B had less intraoperative bleeding, shorter operation time and less postoperative pain score. There was significant difference between groups (P<0.05). Compared with group A, group B had higher bone mineral density, thicker hyperosteogeny, larger reduction rate of cyst volume and shorter cyst healing time. There was significant difference between groups(P<0.05). The levels of serum neuropeptide Y (NPY), substance P (SP) and nerve growth factor (NGF) in group B were lower than those in group A at 2 h and 12 h after operation, β Endorphins（β-EP) was higher than that in group A(P<0.05). There was no significant difference in the incidence of complications between the two groups (P>0.05). Conclusions: Compared with curettage for jaw cyst, fenestration decompression has significant advantages, which can reduce intraoperative bleeding, shorten operation time, reduce postoperative pain and promote postoperative recovery.

Objective: To investigate the clinical application of large-scale jaw cyst fenestration and the use of nasal endoscope for removing the low-impacted wisdom teeth. Methods: Nine patients with large jaw dentigerous cysts were treated with a drainage channel at the site of the molar or posterior molar or the posterior vestibular groove of the molar. The nasal endoscope was used to connect each pocket of cyst and remove the low-impacted wisdom teeth being squeezed by the cyst. The occluder was used to maintain the open window and keep daily flushing treatment. The size of the cyst and the bone changes around the wall were observed to evaluate the clinical effect of this method. Results: After 6-18 months of follow-up, the treatment of 9 cases of dentigerous cysts was effective, and the effective rate was 100%. Postoperative reexamination showed that the cystic cavity was significantly reduced. Local deformity and injury were also restored. None of the 3 patients underwent a secondary curettage and no recurrence was observed. Conclusion: The fenestration treatment of the jaw cyst preserves the shape and function of the jaw bone, and has obvious effects on the improvement of the quality of life of the patient. It is a clinically operative and therapeutically effective treatment method. In the meantime, nasal endoscope also plays a key role in guiding the connection of each pocket of cyst and extracting the impacted teeth displaced by the cyst. [ABSTRACT FROM AUTHOR]

Objective: To compare the operative effect, quality of life and prognosis of patients with cyst of jaw treated by fenestration and decompression and traditional curettage. Methods: The clinical data of 90 patients with jaw cyst who were admitted to our hospital from January 2016 to July 2018 were retrospectively selected. The patients were divided into group A (n=45, traditional curettage) and group B (n=45, fenestration and decompression) according to different surgical methods. The curative effect, clinical indicators, quality of life and prognosis were compared between the two groups. Results: The total clinical effective rate of group B was 97.78% (44/45), which was higher than 84.44%(38/45) of group A (P<0.05). The wound healing time, the operation time in group B were shorter than those in group A, the intraoperative blood loss was less than that in group A(P<0.05). The scores of emotion, appearance, taste, pain, saliva, chewing and other items in the last follow-up of the two groups were higher than those in group A (P<0.05). The rate of complications and recurrence in group B was lower than that in group A (P<0.05). Conclusions: Compared with the traditional curettage, the fenestration and decompression has a significant effect on the operative effect, quality of life and prognosis, and has a higher clinical application value.

Objective: To study the effect of combined determination of working length in the treatment of jaw cyst involved teeth root canal. Methods: A total of 36 patients with jaw cyst involved teeth(135 bad teeth, 186 root canals), which needed to be treated with root canal therapy, were randomly divided into experiment group(n=93 root canals) and control group(n=93 root canals). The root canal length of experiment group was measured by electrometric method combined with paper point method,while the root canal length of control group, by electrometric method combined with X-ray. The filling effects of the two groups were compared after root canal filling. Results: The full filling rate(90.32%) of the experiment group was significantly higher than that(79.57%) of the control group(P<0.05).Conclusion: The electrometric method plus paper point method is used to measure the root canal length in the treatment of patients with jaw cyst involved teeth root canal, which has a higher accuracy, better filling effects and more safety.

Objective: This study aims to evaluate the clinical effect of oral repair membrane and β-tricalcium phosphate (β-TCP) on the treatment of jaw cyst., Methods: A retrospective analysis was performed on 81 cases of jaw cysts, and clinical data were collected for the comparison of traditional surgical curettage (group A, 27 cases), biofilm covering bone wounds after curettage (group B, 27 cases), and β-TCP filling combined with biofilm covering., Results: No recurrence occurred in 81 patients, and no significant difference in preoperative CT value among the three groups (P<0.05). Follow-up CT reexamination 3, 6, and 12 months after operation showed significant differences among the three groups of CT values (P<0.05). Group C was better than Group B or Group A (P<0.05)., Conclusions: In traditional jaw cyst curettage, the application of biofilm exhibited good osteogenesis effect, and the combined application of β-TCP and biofilm exerted a better effect.

Decompression and curettage can result are effective as treatments for large jaw cysts, which are common diseases in the clinic. Based on a treatment used in a previous study, this paper proposes a "three-step method" to treat large jaw cyst and repair the bone defect by decompression, curettage, and autologous dental bone powder implantation. This paper introduces the processes and key points of the operation involved in the abovementioned method.
