Experts consensus on diagnostic and therapeutic strategies for malocclusions at early developing stage FANG Bing, JIN Zuo-lin, BAI Yu-xing, WANG Lin, ZHAO Zhi-he, LI Wei-ran, BAI Ding, HE Hong, LIU Yue-hua, HU Min, SONG Jin-lin, CHEN Li-li, CAO Yang, WU Ting-xi, LI Song, LI Huang, SHI Jie-jun, CHU Feng-ting Shanghai Journal of Stomatology    2021, 30 (5): 449-455.   DOI: 10.19439/j.sjos.2021.05.001 Abstract （1724）      PDF （861KB）（3103）       Knowledge map    Early orthodontic intervention remains a controversial notion in current dental care regime. Whilst early orthodontic treatment for children is the province for orthodontic specialists, a growing number of general practitioners, who may not possess sufficient specialty knowledge, are also involved, raising the concerns about the propriety and quality of their treatment modalities. However, orofacial development of children and adolescents is in a very complicated environment. Comprehensive theoretical knowledge and a great wealth of practical experience are required to ensure the final treatment effect. The possible complications should be kept under control and fully informed to patients and their parents. In order to unify and standardize early orthodontic treatment protocol and help to promote healthy and orderly development of early orthodontic treatment, this consensus summarized the practical experience of orthodontic experts from many famous colleges and affiliated hospitals for clinical reference.

Effect of HBXIP on biological function and PI3K/Akt signaling pathway of adenoid cystic carcinoma cell line ACC-M MENG Xue, QI Xiao-yu, WANG Qiu-xu, LIU Wei-xian Shanghai Journal of Stomatology    2017, 26 (4): 389-394.   DOI: 10.19439/j.sjos.2017.04.008 Abstract （425）      PDF （4378KB）（1962）       Knowledge map    To study the effect of hepatitis B virus X protein binding protein (HBXIP) on proliferation, migration and invasion of adenoid cystic carcinoma cell line ACC-M, and the possible mechanism of PI3K/Akt signaling pathway. METHODS: HBXIP plasmid was transfected into ACC-M. The cells were divided into experimental group (transfected with plasmid pEGFP-N1-HBXIP) control group (non-transfected group) and blank control group (vector group, pEGFP-N1). RT-PCR was used to detect the expression HBXIP in ACC-M; MTT assay, transwell chamber experiments and scratches over the proliferation of HBXIP were utilized individually to evaluate the influence of HBXIP on ACC-M expression, migration and invasion; Western blotting was used to detect the protein expression of Akt, p-Akt, PI3K, p-PI3K and S100A4 after overexpression of HBXIP. Statistical analysis was performed using SPSS 18.0 software package. RESULTS: MTT results showed that the number of surviving cells of experimental group was significantly higher than the control group (P<0.05); Scratch test results showed that the cell mobility of the experimental group was significantly higher than the control group (P<0.01); Transwell chamber experiments showed that the number of cell invasion of the experimental group was significantly higher than the control group (P<0.01); Western blotting results showed that compared with the control group, the expression of p-Akt, p-PI3K and S100A4 in the experimental group with overexpressed HBXIP was relatively increased. CONCLUSIONS: Overexpression of HBXIP gene promotes ACC-M proliferation, invasion and migration. Further, ACC-M proliferation, invasion and migration may be promoted by increased Akt, PI3K phosphorylation and S100A4 protein expression. Reference | Related Articles | Metrics

The orthodontic therapeutic principles for malocclusions concurring with temporomandibular joint disorders SHEN Gang Shanghai Journal of Stomatology    2021, 30 (4): 337-343.   DOI: 10.19439/j.sjos.2021.04.001 Abstract （1120）      PDF （2978KB）（1519）       Knowledge map    The biological nature of temporomandibular joint (TMJ) featuring adaptive remodeling allows for TMJ structural changes in response to external stimuli, including alterations in occlusion and in mandibular posture. Correlative susceptibility exists between malocclusions and TMJ disorders (TMD), evidenced by high incidence of TMD coinciding with skeletal originated malocclusion with facial prognathsim (Angle Class I skeletal II high angle). Clinical manifestations include markedly retruded mandible together with increased overjet, or mandibular transverse deviation, due to condylar pathological resorption. It is critically imperative to execute differential diagnosis between the routine malocclusions and those infringed with TMD. The prime stipulations governing the orthodontic procedures include the patient's notification of the existential TMD conditions prior to any orthodontic interventions, close inspections of TMD developments during the treatment, and a specially designed retention protocol aftermath. For the cases where severe overjet and mandibular displacement occur as a result of TMD, some specific orthopedic modalities can be implemented to improve the occlusion by restoring the shifted mandible. TMD conditions are also expected to be relieved with mandibular repositioning, which encourages new bone formation in the degraded condyles. The newly developed clear version of orthopedic appliances, namely, S8-SGTB, S8-SGHB, S9 and S10 are of promising efficacy in treating this category of patients.

Clinical efficacy of the combination of miniscrew with clear aligner in controlling the roller coaster effect MA Xiao-qing, XIANG Fei, FAN Ming-yue, SONG Yi, WANG Xiao-hui, ZHANG Ling, QIAN Wen-hao Shanghai Journal of Stomatology    2022, 31 (2): 193-197.   DOI: 10.19439/j.sjos.2022.02.015 Abstract （991）      PDF （1173KB）（1456）       Knowledge map    PURPOSE: To investigate the clinical efficacy of miniscrew in controlling the roller coaster effect in long-distance space closure with clear aligner. METHODS: Sixteen adult patients with bimaxillary protrusion were selected. All cases were treated with clear aligner and their four first premolars were extracted. G6 was designed in all cases. In the experimental group, four miniscrews were inserted at the beginning of treatment to control the teeth in three dimensions; while in the control group, the miniscrews were not applied until obvious roller coaster effect appeared. Paired t test was used to analyze the data with Graphpad Prism 6.0 software package. RESULTS: All the extraction space was closed successfully and the lateral profile was improved significantly. The torque of the upper incisor was under well control and no roller coaster effect happened in the experimental group; while in the control group, the lingual inclination of the upper incisors and open bite of the posterior teeth developed(P<0.05). After the miniscrews intrusion of the upper anterior teeth, the occlusion relationship improved significantly. CONCLUSIONS: Miniscrews effectively prevents and eliminates the roller coaster effect in the process of long-distance space closure with clear aligner. Reference | Related Articles | Metrics

METHODS: Four hundred patients who required removal of impacted mandibular third molars were included in the study. They were divided into group A and group B randomly. Patients in group A received distal incision flap and group B underwent angular incision flap. The effect of flap design on surgical time, incidence of dry socket, pain, swelling and trismus was evaluated postoperatively. Data analysis was carried out with SPSS 13.0 software package. RESULTS: The surgical time was longer in group A than in group B 3 days postoperatively. Facial swelling and trismus were less in group A than in group B 3 days postoperatively. There was no significant difference in two groups 7 days postoperatively. CONCLUSIONS: The distal incision flap design can release facial swelling and trismus in surgical removal of impacted mandibular third molars. Reference | Related Articles | Metrics Cited: Baidu(2)

Analysis of the possible causes of endodontic treatment failure by inspection during apical microsurgery treatment QIAN Wen-hao,HONG Jin,XU Pei-cheng Shanghai Journal of Stomatology    2015, 24 (2): 206-209.   Abstract （795）   HTML （7）    PDF （1009KB）（1264）       Knowledge map    PURPOSE: To analyze the possible causes of previous endodontic treatment failure by microscopic inspection during apical microsurgery. METHODS: Two hundred and eighty-nine teeth of previous endodontic treatment failure were collected from patients in Shanghai Xuhui District Dental Center, between January 2006 and January 2014. All surgical procedures were performed by using an operating microscope, and 238 roots were included in the study. The surface of the apical root to be resected or the resected root surface after methylene blue staining was examined during the surgical procedure and inspected with 26 magnification to determine the state of the previous endodontic treatment by using an operating microscope. Fisher's exact test was used to analyze the data with SPSS 19.0 software package. RESULTS: Among the 238 roots with periapical surgery, analysis of the reasons for previous endodontic treatment failure included leaky canal (29.41%), missing canal (15.55%), underfilling (15.55%), anatomical complexity (7.98%), overfilling (4.20%), apical fenestration (4.20%), iatrogenic problem (3.36%), apical calculus (2.52%), apical cracks (1.68%) and unknown reasons (15.55%). The frequency of possible failure causes and tooth position were closely correlated (P<0.001). CONCLUSIONS: Apical microsurgery can better inspect possible causes of previous endodontic treatment failure, in order to improve the success rate of endodontic treatment.

Comparison of root resorption between self-ligating and conventional brackets using cone-beam CT LIU Yun,GUO Hong-ming Shanghai Journal of Stomatology    2016, 25 (2): 238-241.   Abstract （527）   HTML （11）    PDF （872KB）（1250）       Knowledge map    PURPOSE: To analyze the differences of root resorption between passive self-ligating and conventional brackets, and to determine the relationship between passive self-ligating brackets and root resorption. METHODS: Fifty patients were randomly divided into 2 groups using passive self-ligating brackets or conventional straight wire brackets (0.022 system), respectively. Cone-beam CT was taken before and after treatment. The amount of external apical root resorption of maxillary incisors was measured on CBCT images. Student's t test was performed to analyze the differences of root apical resorption between the 2 groups with SPSS17.0 software package. RESULTS: No significant difference(P> 0.05) in root resorption of maxillary incisors was found between passive self-ligating brackets and conventional brackets. CONCLUSIONS: Passive self-ligating brackets and conventional brackets can cause root resorption, but the difference was not significant. Passive self-ligating brackets do not induce more root resorption. Reference | Related Articles | Metrics Cited: Baidu(9)
