BACKGROUND:It is believed that the splintage can promote periodontal tissue repair and improve the prognosis of loose teeth. However, the force of the splint is associated with the rigidity of the splint and adaptation between the teeth and the splint.
OBJECTIVE: To evaluate the therapeutic effects of the nylon composite resin periodontal splint, the
fiber-reinforced composite periodontal splint and the bracket periodontal splint on the treatment of severe periodontitis of the mandibular anterior teeth.
METHODS:Seventy-two patients with severe periodontitis of the mandibular anterior teeth were randomized into 3 groups, with 24 cases in each group: nylon composite resin periodontal splint, fiber-reinforced composite
periodontal splint and bracket periodontal splint groups. The clinical effects of the three kinds of periodontal splints and periodontal indexes were compared at 1, 6 and 12 months after splinting.
RESULTS AND CONCLUSION: The clinical effects in the group of the fiber-reinforced composite periodontal
splint were significantly better than those in the other two groups at 1, 6, 12 months, which were 100%, 100% and 95.8%, respectively. The plaque index, bleeding index, and pocket depth were worse in the group of the nylon
composite resin periodontal splint than the other two groups (P < 0.05). Results suggest that the fiber-reinforced composite periodontal splint is preferred to preserve the loosened teeth with severe periodontitis.

Objective:To evaluate the effectiveness of minimal flap surgery in the treatment sub-gingival caries ( class V cavities) . Methods:57 teeth(4 incisors, 13 canines, 38 premolars and 2 molars) with sub-gingival caries in 42 patients were treated by com-bined gingival flap surgery. Sub-gingival caries was fully exposed and the lesion was fully removed, then the deffects were filled with flowing resin. Before operation, 6 and 12 months after treatment, PD, SBI and gingival recession were examined. Results:Success rate of the treatment was 98. 25%. No statistically significant difference of the indexes was found during 12-month-follow up. Conclu-sion:Minimal flap surgery is effective for the treatment of sub-gingival caries ( class V cavities) .

Objective:To explore the relationship of NSCL/P with MTHFR gene polymorphism in Xinjiang Uyghur and Han popula-tion and the ethnic difference.Methods:rs1801131 and rs1801133 polymorphism was detected by SNaPshot genotype method in 170 children with NSCL/P and 100 healthy controls of Uyghur and Han population.Results:Rs1801133 TT and T allele was statistically difference between 2 nationalities(P <0.05),Rs1801133 CT and CT +TT genotypes in total case group and control group were sta-tistically different(P <0.05);Rs1801131 and rs1801133 conjoint analysis showed that between the 2 nationalities and between case and control groups of total population were statistically different(P <0.05);rs1801131 genotype between 2 nationalities or total cases and controls were not statistically different(P >0.05).Conclusion:Rs1801133 TT and T allele in Han nationality are more likely to suffer from NSCL/P than in Uyghur,rs1801133 CT and CT +TT genotypes are protective factors.Rs1801131AC and rs1801133CC conjoint is relevant to NSCL/P,and the risk in Uyghur is higher than in Han.MTHFR rs1801131 gene polymorphism may not be relat-ed with NSCL/P in Uyghur or Han.

OBJECTIVETo evaluate methodological and reporting quality of the randomized controlled trials on cognitive-behavioral therapy(CBT) on temporomandibular disorders(TMD).
METHODSThe electronic databases of Medline via Ovid, EMBASE, Cochrane Central Register of Controlled Trial, CBM and CNKI, and five Chinese stomatological journals were included to collect randomized controlled trial(RCT) and quasi-RCT(qRCT) on CBT on TMD. Data were assessed using the quality assessment criteria recommended by the Cochrane Collaboration, and the reporting quality was assessed using the consolidated standards of reporting trials (CONSORT) checklist.
RESULTS232 articles were collected by the search strategy, of which 5 (3 RCTs and 2 qRCTs) met the inclusion criteria. The methodological quality varied among the studies with 2 scored as B and 3 as C. The highest score evaluated by the CONSORT checklist was 24.
CONCLUSIONThe methodological qualities of included studies on CBT on TMD are generally low, and its reporting quality which is checked by CONSORT is also unsatisfactory yet.

Objective:To compare the variability of midpalatal suture maturation ratio of skeletal class Ⅰ malocclusion adults between genders,among positions and vertical skeletal patterns.Methods:173 skeletal class Ⅰ malocclusion adult patients were included and divided into 6 groups according to GoGn-SN Angle and gender:dolichofacial group(male 22,female 24)with GoGn-SN>37.7°,me-sofacial Group(male 30,female 33)with 27.2°≤GoGn-SN≤37.7° and brachyfacial group(male 33,female 31)with GoGn-SN<27.2°.The midpalatal suture maturation ratio in the corresponding area of anterior,medial and posterior region were measured and calculated by Mimics 21.0 software,the overlap of the anterior nasopalatine canal with the measurement site was recorded.Results:In the comparison of different genders,there was a statistically significant difference between males and females in the brachyfacial an-terior region(P<0.001).In the comparison of different positions,except the females among the anterior,middle and posterior regions in brachyfacial group(P>0.05),there were statistical differences in the fusion degree of the other parts of the palate suture(P<0.05),and it gradually decreased from the posterior region to the anterior region.In the comparison of different vertical skeletal pat-terns,there was no statistical difference except the difference between the mesofacial and brachyfacial and dolichofacial groups in the middle area of males(P>0.05),and the difference was significant among brachyfacial,dolichofacial and mesofacia groups in the ante-rior area of females(P<0.05).Rates of anterior nasopalatine duct influence measurements were statistically significant in the compari-son between dolichofacial and brachyfacial males,and between brachyfacial males and brachyfacial females(P<0.05),the remainder was not statistically significant(P>0.05).Conclusion:In adult patients,the palatal suture is not completely fused,and palatal mi-croimplant anchorage should be avoided in the midpalatal suture.
