Gut Microbiota in Interaction Effects of Periodontitis and Hyperlipidemia YAN Fuhua, HUANG Yuezhen 2021, 37(2): 95-100.  DOI: 10.13701/j.cnki.kqyxyj.2021.02.001 Abstract ( 317 )   PDF (1022KB) ( 539 )   Periodontitis and hyperlipidemia are common chronic diseases that seriously affect human health. It is reported that there is a positive relationship between them. However, the exact biological mechanisms are still unclear. Intestinal microecosystem is the largest and most complex ecosystem in human body. Multiple studies have confirmed that the gut microbiota can regulate blood lipids and bone metabolism through its own metabolites, affecting host metabolism and immune response. Both periodontitis and hyperlipidemia can cause changes in the composition of intestinal microbiota. This review aims to deliver an overview of the interaction effects of periodontitis and hyperlipidemia via gut microbiota and provide some new ideas and theoretical bases to improve the recognition of relationship between two diseases.

Methods: Thirty permanent molars with complete morphology from the neck to the apical were collected. Three kinds of pulp cavity preparation depth, i.e. 3 mm, 4 mm, and 5 mm and two kinds of margin design were randomly divided into six groups, which were restored with zirconia endocrowns by CAD-CAM technique. The flexural strength test was recorded with the fracture load value and the fracture mode. Results: No matter the butt margin group or the shoulder group, the maximum loading value of the six groups was 3mm<4mm<5mm, however, there was no significant difference between two groups. The maximum load value of the shoulder group was greater than that of the butt margin group, and there was a statistically significant difference between the 3mm and 4mm groups. In the fracture mode of six groups of samples, irremediable fracture was the main one, and all samples in the 5mm group presented irremediable fracture. Conclution: When maxillary short coronal molars were restored with zirconia endocrowns by CAD-CAM technology, the preparation depth of pulp cavity at 3mm and 4mm could meet the requirements of clinical flexural strength, however, no more than 4mm. In addition, the introduction of 1mm dentin shoulder collar could be used as a clinical preparation method to effectively increase the flexural strength of teeth and prostheses.

Methods: Fifty human molars were selected to remove the tooth root and occlusal enamel, and exposed the dentin layer. A 4mm thick composite resin block was piled on the bonding surface. Teeth were sectioned vertically along two perpendicular directions into beams of approximately 1.0 mm2 in cross-section. Fifty specimens were randomly divided into five groups: Group C (control), Group A1 (2.5%NaClO solution for 1 hour), Group A2 (2.5%NaClO solution for 2 hours), Group B1 (5.25%NaClO solution for 1 hour), and Group B2 (5.25%NaClO solution for 2 hours). The microtensile bond strength (μTBS) of five groups was tested. The stereomicroscope and SEM images of the fractured areas were used to determine the fracture mode of specimens. Results: The microtensile strength values of four experimental groups were significantly reduced compared to the control group with the increase of the concentration and the action time of NaClO solution. The action time of NaClO solution had no significant effects on the resin dentin bonding strength (P>0.05). The concentration of NaClO solution had no significant effects on the dentin bonding strength of the resin (P>0.05). However, there was an interaction effect between the concentration and action time of NaClO solution (P<0.05). Scanning electron microscope and stereo microscope showed that five groups of samples mainly fractured at the bonding interface. Conclusion: The micro-tensile bonding strength of the adhesion interface between dentin and resin can be reduced with the increase of concentration and action time of NaClO solution.

Methods: Four experimental groups were designed, namely 0 (Control group), 0.1, 1.0, and 10 g/L EGCG groups. The antibacterial ability of experimental adhesives was assessed by live/dead bacterial staining and MTT assay. The shear bond strength (SBS) and degree of conversion (DC) were evaluated to assess the bonding performance of experimental adhesives. Results: Comparing with the Control group, the incorporation of EGCG into adhesive significantly increased the antibacterial ability (P<0.05), which had positive correlation with EGCG concentration. No negative influence on the SBS and DC was detected for 0.1 and 1.0 g/L EGCG groups (P>0.05), but the value of 10 g/L EGCG group significantly decreased (P<0.05). Conclusion: The addition of 1.0 g/L EGCG into dental adhesive could exert positive antibacterial ability without hampering the polymerization of dental adhesive.

Methods: PLLA/HA composites with different proportions were prepared by melt blending method. PLLA/HA composites were divided into PLLA, PLLA-1%HA, PLLA-3%HA, PLLA-5%HA, and PLLA-7%HA groups according to different HA mass percentages. The tensile and flexural properties were tested by electronic universal tester, and the impact strength of the composites was tested by pendulum impact tester. 16 primary anterior teeth were collected in vitro, and the compressive modulus and strength of root dentin were tested. Results: There was no significant difference in flexural modulus and impact strength among the five groups (P>0.05), but there were significant differences in tensile strength and flexural strength (P<0.05). The tensile strength and flexural strength of PLLA/HA composites in PLLA-1%HA, PLLA-3%HA, and PLLA-5%HA groups were lower than those in PLLA group, but there was no significant difference among three groups (P>0.05). The mean compressive modulus and strength of the root dentin were 3.63 GPa and 128.03 MPa, respectively. Conclusion: PLLA-1%HA, PLLA-3%HA, and PLLA-5%HA composites are expected to be the materials of root canal post in primary teeth due to the certain mechanical properties, but their mechanical properties need to be further improved.

Methods: From January 2020 to July 2020, 90 children who received midazolam sedation in the Stomatology Department of Shenzhen Children's Hospital were randomly divided into two groups, 45 in each group. Midazolam was given intramuscularly (0.2 mg/kg) in the intramuscular group and orally (0.6 mg/kg, maximum single dose 20.0 mg). Sedation effectiveness was assessed with the Ramsay Scale, treatment compliance with the Frankl Scale, and treatment completion with the Houpt Scale. At the same time, the onset time of drugs, heart rate, blood oxygen saturation, and intraoperative and postoperative adverse reactions were recorded. Results: The onset time of the intramuscular group (13.0±2.0min) was significantly shorter than that of oral group (15.6±1.8min, P<0.05). The median scores of the Ramsay (Z=-1.089, P=0.276), Frankl (Z=-0.0863, P=0.388), and Houpt scales (Z=-1.854, P=0.064) were not statistically significant, and the distribution of scores was similar (P<0.05). There was no significant difference in the sedation success rate (χ2=0.178, P>0.05) and treatment success rate(χ2=3.103, P>0.05) between two groups. And there was no significant difference in the incidence of side effects(χ2=0.080, P>0.05). Conclusions: Oral or intramuscular midazolam has similar sedative effectiveness, and both of them are safe and effective sedation methods in the treatment of dental anxiety in children, but the onset time of sedation is shorter in the intramuscular injection group.

Effect of Two Different General Anesthesia Methods on Immune Function of Oral Squamous Cell Carcinoma Patients: A Randomized Controlled Study YIN Fang, LI Jinjie, GONG Ping, ZHOU Tengpeng, LIU Kebin, ZHANG Tiejun 2021, 37(2): 153-156.  DOI: 10.13701/j.cnki.kqyxyj.2021.02.014 Abstract ( 163 )   PDF (760KB) ( 120 )   Objective: To evaluate the effects of two different general anesthesia methods on perioperative immune function of patients undergoing radical treatment of oral squamous cell carcinoma and immediate repair of free flap defect. Methods: A total of 40 patients with oral squamous cell carcinoma who underwent elective surgery were enrolled and randomly divided into group DP and group S (n=20). In group DP, dexmedetomidine and propofol were used as main anesthetics, and in Group S, sevoflurane was used as the main anesthetic. Other anesthetics were the same in both groups. Venous blood samples were taken at six time-points: 30 minutes before anaesthesia (T0), 3 hours after anaesthesia (T1), at the end of the operation (T2); and 6 hours (T3), 24 hours (T4) and 48 hours (T5) after operation. The serum concentrations of immunoglobulin (IgA, IgM, IgG) and immunocytokines (IL-2, IL-6, IL-10, sIL-2Rα) were measured. Results: All indicators were statistically different from T0 at multiple time points within groups (P<0.05), but immunoglobulins were not statistically different between two groups, while immunocytokines were statistically different between two groups except T0 (P<0.05). At T4 and T5, the concentrations of sIL-2Rα and IL-6 in Group S were higher than those in group DP, while the concentration of IL-2 in group S was lower than that in group DP (P<0.05). The concentration of IL-10 in Group S was higher than that in group DP at T1 to T4 (P<0.05). Conclusion: There was no statistical difference on immuneglobulins related to humoral immunity in patients under different general anesthesia methods. However, the level of IL-2, IL-6, IL-10, and sIL-2Rα in circulation can be better maintained by intravenous anesthesia based on propofol and dexmedetomidine, which may be more helpful to relieve the immune suppression induced by surgery.

Methods: 160 semi-mandibles of 80 patients were recruited in this study. The CBCT data were reconstructed to evaluate the visibility, diameter, and location within the mandible of MIC. Results: The rate of the MIC identification had a range of 52.5%-77.4%, showing an upward tendency from the central incisor to the first premolar. The mean distance from MIC to the labial cortex were (3.74±1.23) mm in straight line and (3.54±1.18) mm in tangential direction respectively (P＜0.005). Conclusion: The MIC runs slightly downward from the foramen to the midline, with its diameter and visibility decreasing. It locates closer to the labial cortex as constantly as (3.54±1.18) mm in different tooth sites but remains below the link line of bilateral mental foramens with different level ranging from (3.79±1.78) mm to (8.41±2.91) mm. The harvesting of bone graft in the interforaminal region should be limited within the distance range. References | Related Articles | Metrics

Methods: The clinical, imaging, serological, pathological, and therapeutic features of 31 patients with IgG4-RD diagnosed in the first affiliated Hospital of Xinjiang Medical University were analyzed, and IgG4-RD responder index was used to evaluate disease activity and damage. Results: Among the 31 patients, there were 18 males and 13 females, with an average age of (59.1±9.12) years. The median time from onset to diagnosis was 10 months (range 1-120 months). Six cases were misdiagnosed at the first diagnosis, with a misdiagnosis rate of 19.35%. 32.26% of the patients were complicated with allergic diseases. Imaging revealed that all patients had organ occupying, and all patients had 2 or more organs involved, mainly salivary gland (77.42%), followed by lymph nodes, lacrimal gland, bile duct, and so on. The IgG4-RD responder index was 7.13±3.25, and it was positively correlated with the involved organs (r=0.15, P<0.0001). Serum IgG4 increased in 93.55% of these patients, and it was positively correlated with serum IgG (r=0.54, P<0.01). Histopathology showed infiltration of lymphatic plasma cells, obvious proliferation of lymphoid follicles and irregular fibrosis between tissues. Among the 25 patients who took glucocorticoid drugs, one patient was treated with rituximab because of ineffective treatment, and two patients were treated with immunosuppressants. The follow-up time was (25.89±14.02) months. Twelve patients had good results after treatment, the level of IgG4 decreased. Twelve patients had recurrence during treatment, with a recurrence rate of 48%. One case died of heart attack during treatment. Conclusion: IgG4-RD is a multi-system fibro-inflammatory disease, which is common in middle-aged and elderly men. Enlargement of salivary glands, lymph nodes, lacrimal glands, and internal organs is a common clinical manifestation. Glucocorticoids and biological agents are effective in the treatment, but there is a recurrence. References | Related Articles | Metrics
