    PURPOSE: To investigate the relationship between upper airway and cranial-facial growth pattern among teenagers with normal occlusion. METHODS: The study subjects consisted of 52 boys and 64 girls with normal occlusion. Their cephalometric radiographs were obtained. The sagittal diameter of upper airway was analyzed according to gender and different growth pattern. The relationship of upper airway diameter and cranial-facial formation was evaluated by stepwise regression analysis using SPSS 21.0 software package. RESULTS: There was no significant difference between male and female about upper airway diameter in teenagers, also no difference was found among different growth patterns. Regression analysis showed that upper airway was associated with some cranial-facial formation parameters. CONCLUSIONS: Although there is no significant difference in the upper airway diameters among different growth patterns, there is still certain association between cranial-facial formation and upper airway in adolescents.

    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.

    Orofacial myofunctional therapy improves facial morphology of children with obstructive sleep apnea after adenotonsillectomy
    SHAN Hua-qing, WANG Yu-hui, YU Li-ming, LI Xiao-yan, LIU Yue -hua
    Shanghai Journal of Stomatology    2021, 30 (4): 389-393.   DOI: 10.19439/j.sjos.2021.04.010
    Abstract735)      PDF (790KB)(733)      
    PURPOSE: This study investigated the effectiveness of orofacial myofunctional therapy(OMT) in improving facial morphology of children with obstructive sleep apnea (OSA) after adenotonsillectomy (AT). METHODS: Ten children aged from 4-7 years with persistent oral breathing for more than 1 month after adenotonsillectomy were chosen to receive orofacial myofunctional therapy. The patients were required to take photos before and after orofacial myofunctional therapy. In order to compare the soft changes before and after OMT treatment, twelve representative mark points were selected and used for proportion and angle measurements. Graphpad Prism 8 statistical software was used for statistical analysis, to compare the differences in facial morphology of patients before and after treatment. RESULTS: Compared with before OMT, a significant difference was found in the proportion of Sn-Ls/Sn-Stms(P=0.0002), Sn-Stms/Sn-Me'(P<0.05), as well as in the angle of Gs-Sn-Pos (P<0.05), nasolabial angle(P=0.0005), mentolabial angle (P=0.0026) after OMT treatment. CONCLUSIONS: Orofacial myofunctional therapy can be considered as an effective complementary treatment for OSA patients with oral breathing after adenotonsillectomy.

    Clinical study of the effect of fixed Twin-block on adolescent skeletal ClassⅡmalocclusion
    MA Xiao-qing, ZHAO Ning, XIANG Fei, ZHOU Man-li, QIAN Wen-hao
    Shanghai Journal of Stomatology    2021, 30 (4): 414-418.   DOI: 10.19439/j.sjos.2021.04.015
    Abstract361)      PDF (969KB)(305)      
    PURPOSE: To evaluate the retention ability of fixed Twin-block appliance and its clinical effect on adolescent skeletal ClassⅡmalocclusion. METHODS: Twenty-six skeletal ClassⅡdivision 1 adolescents (M:12, F: 14; age:11~13 years, average: 11.8 years) were chosen and fixed Twin-block appliance was used to guide the mandibular protrusion for one year. Before and after treatment, cephalometric films were taken to observe the skeletal, dental and soft tissue changes. Graphpad Prism 6.0 software was used for Student's t test. RESULTS: There was no loosening or destruction of the appliance during the treatment and the profile of all cases was improved significantly. The indexes that showed significant difference(P<0.05) included the mandibular length and position (Co-Gn, SNB, ANB, Pog-VL, Pos-VL), the inclination and position of the maxillary incisors(U1-VL, U1-SN), the sagittal position of the mandibular dentition(L1-VL, L6-VL). The indexes that showed insignificant difference(P>0.05) included the mandibular plane(MP-SN), the length and position of the maxilla (SNA, A-VL), the vertical position of the maxillary incisor(U1-HL), the position of the maxillary posterior teeth(U6-VL, U6-HL), the mandibular incisor inclination(IMPA) and the vertical position of the mandibular dentition(L6-MP,L1-MP). CONCLUSIONS: Fixed Twin-block appliance can enhance the mandibular anchorage, effectively promote the mandibular growth and improve the facial profile.

    Abstract262)   HTML0)    PDF (865KB)(239)      
    PURPOSE: To explore the effect and mechanism of activated peripheral blood mononuclear cell (PBM) on the growth and apoptosis of oral squamous carcinoma cells in vitro. METHODS: ELISA, RT-PCR, MTT and flow cytometry were used to detect cytokines secretion and oral squamous carcinoma cell growth and apoptosis affected by activated PBMCs with PHA. The data was analyzed using SPSS17.0 software pakage. RESULTS: The cytokines secretion, mRNA expression of granzyme B and perforin, inhibition of growth and induction of apoptosis of oral squamous carcinoma cells treated by the activated PBMCs with PHA were significantly higher than the control groups (P<0.05). CONCLUSIONS: The human PBMC can be activated effectively with the stimulations of PHA, which can significantly inhibit growth and induce apoptosis of oral squamous carcinoma cells in vitro.

    Shanghai Journal of Stomatology    2017, 26 (4): 425-428.   DOI: 10.19439/j.sjos.2017.04.015
    Abstract502)      PDF (2731KB)(789)      
    To observe the clinical effect of pulpotomy for cariously exposed permanent teeth with closed apices and provide guidance for clinical application. METHODS: Sixty-two cariously exposed permanent teeth with closed apices and vital pulps were included. Preoperative pulpal and periapical diagnosis was established. The teeth were divided into two groups, the experimental group was treated with pulpotomy(32 cases), and the control group was treated with one-visit root canal therapy (one-visit RCT) (30 cases). Clinical and radiographic evaluation was completed at 1 month, 3 months, 6 months, 12 months postoperatively. Statistical analysis was performed using SPSS 18.0 software package. RESULTS: After 1 year, the success rate of pulpotomy was 93.75%, and the success rate of root canal therapy was 93.10%. There was no significant difference between pulpotomy and root canal therapy( χ2=0.010,P=0.665). CONCLUSIONS: The advantages of pulpotomy are less invasive and less tooth destruction. It is a successful treatment option for cariously exposed pulps in mature permanent teeth.
