ABSTRACT
Objective@#To evaluate the clinical efficacy of CAD/CAM glass-ceramic onlays in molars with complicated oblique crown fracture within 3.0 mm subgingival. @*Methods@#Fifty-six molars from 56 patients with complicated oblique crown fracture within 3.0 mm subgingival were recruited after endodontic treatment and divided into 2 groups according to the restorative methods used. The glass-ceramic onlays group was restored with CAD/CAM glass-ceramic onlays, while the all-ceramic crown group received CAD/CAM all-ceramic crowns. The success rates of the restorations were analyzed, and the sulcus bleeding index (SBI), plaque index (PLI), and gingival index (GI) were recorded at the prerestoration and postrestoration stages. @*Results @#After one year of follow-up, the success rate of the glass-ceramic onlay group was 96.4%, and the success rate of the all-ceramic crown group was 92.9%. The difference was not statistically significant (P > 0.05). No differences in SBI, PLI, or GI were found between the glass-ceramic onlay group and the all-ceramic crown group (P > 0.05).@*Conclusion@#Conclusion
ABSTRACT
Objective: To examine oral health condition of the military officers and soldiers before and after military field training. Methods: After technical training,investigators went to a military field training place to carry out the oral health examination at the beginning and at the time of ending,respectively. Basic examinations included oral ulcer conditions,sulcus bleeding index(SBI) and plaque index(PLI). Results: 145 military officers and soldiers were consistent with inclusion criteria. Compared with those before field training,at the end of training the incidence of oral ulcer was significantly increased(P ＜ 0. 05); SBI of 16,26,36 and 46 was significantly higher(P ＜ 0. 05); PLI of 16,26,36 and 46 was significantly higher(P ＜ 0. 05). Conclusion: Oral health condition of military officers and soldiers may become poor during field training,corresponding oral health care should be emphasized.
ABSTRACT
Objective:To study the changes of oral health indexes in adolescent orthodontic patients under different brushing time, and to provide basis for the orthodontists to give effective dental health promotion in clinic.Methods:A total of 123 adolescent orthodontic patients were included, and they were divided into 1-3min, 3-5 min, 5-7 min and 7-10 min groups based on the brushing time recorded in the period of orthodontic treatment.The relationship between different brushing time and oral health indexes was evaluated 1,3,and 6 months after experiment, such as sulcus bleeding index(SBI),plaque index(PLI), debris index-simplified(DI-S) and enamel demineralization index(EDI).Results:Compared with 1-3 min and 3-5 min groups, the SBI, PLI, and DI-S of the patients in 5-7 min group were significantly reduced(P0.05).Conclusion:Brushing teeth more than 5 min can improve the oral hygiene significantly and the best time is 5-7 min;the orthodontists should require the patients to brush teeth at least for 5 min.
ABSTRACT
Objective To investigate the treatment effect of recombinant bovine basic fibroblast growth factor (rb-bFGF) in patients with gingivitis and its influence on gingival sulcus bleeding index. Methods Sixty-eight patients with gingivitis treated in our hospital were randomly divided into control group (34 cases) and observation group (34 cases). The control group were given basic periodontal therapy, while the observation group were treated with rb-bFGF. The clinical effects, gingival sulcus bleeding index (SBI) before and after treatment, and the recurrence were compared between the two groups. Results After treatment, the total effective rate (97.06%) of the observation group was significantly higher than that of the control group (70.59%), the difference was statistically significant (P<0.05). The SBI of the observation group was significantly lower than that of the control group at 1 and 2 weeks after treatment (P<0.05). The recurrence rate of the observation group (5.88%) was significantly lower than that of the control group (23.53%) (P<0.05). The incidence of complications such as pain, periodontal abscess, bromopnea and loosening was significantly lower in the observation group (8.82%) than in the control group (32.35%). The difference was statistically significant (P<0.05). Conclusion After rb-bFGF treatment, the symptoms of toothache and gingival swelling disappear, normal function of teeth is restored, gingival sulcus bleeding improves significantly, with fewer adverse reactions and obvious clinical effect.
ABSTRACT
Los indígenas de la comunidad de Pykasú del Chaco Paraguayo (etnia Guaraní Ñandéva) no tienen acceso a los servicios de salud bucal por los problemas de distancia y las condiciones viales. Este estudio observacional descriptivo transversal tuvo como objetivo determinar el estado de salud bucodental y dieta de 57 niños de 3 a 13 años de dicha comunidad, utilizando los índices ceod y CPOD, IHO-S y el índice de hemorragia del surco de Mühlemann. La media del ceod en la dentición decidua fue alta (5), en la dentición mixta los valores de ceod fueron moderados (3.5) y el CPOD bajo (1.6), y en la permanente el CPOD fue moderado (3.6) según la escala de la OMS. En cuanto a la escala IHOS, el 65% de la población tenía un valor del índice considerado como regular. Un alto porcentaje de la población (94,8%) presentó hemorragia al sondaje mayor al 10% de las superficies de los dientes sondados. La dieta era equilibrada y el consumo de azúcares y almidones refinados poco frecuente, además del consumo de frutos de la zona de alto contenido de fibras como el algarrobo que es consumido por todos los niños, en su mayoría más de 6 vainas al día.
The indigenous people of the community of Pykasu of the Paraguayan Chaco (ethnicgroup Guaraní Ñandeva) have no access to oral health problems due to distance and roadconditions. This descriptive cross-sectional observational study aimed to determine the oralhealth status and diet of 57 children in this community between 3 and 13 years, using DMFsand DMFT indices, OHI-S and Mühlemann Groove bleeding rate. The average of the DMFs inthe deciduous dentition was high (5), in the mixed dentition DMFs values were moderate(3.5) and DMFT low (1.6) while DMFT values were moderate in the permanent one (3.6)according to the scale of the WHO. In relation to OHI-S scale, the majority of subjects(65%) has an index value considered to be regular. The majority of the population (94.8%)presented hemorrhage on probing greater than 10% of the surfaces of the probed teeth.The diet was balanced and the consumption of sugars and starches refined was littlefrequent, as well as consumption of fruits of the area with high fiber content like the carobtree which is consumed by 100% of the children, mostly more than 6 pods a day.

To evaluate the effects of silicone points polishing on plaque index(PI) and sulcus bleeding index(SBI) after ultrasonic scaling. Forty patients with periodontal diseases were selected for ultrasonic scaling. After scaling,unilateral teeth were randomly assigned for silicone points polishing. PI and SBI were used to evaluate the effects of silicone points polishing. Silicone points polishing significantly reduced PI 12 weeks after scaling. Both in the polishing group and the control group, SBI decreased after scaling. The SBI in the polishing group was significantly lower than that in the control group in the 24 weeks. Silicone points polishing can effectively increase the smoothness of tooth and enhance the effects of uhrosonic scaling.
ABSTRACT
PURPOSE: In this study, we compared low-power CO2 laser treatment to ultrasonic scaling, which is generally approved as a power-driven mechanical instrumentation, and evaluated both of these treatments regarding their clinical effectiveness and change in the volume of in GCF. MATERIAL AND METHODS: 20 patients who had gingivitis were selected. all of patients has no systemic problems. Randomly selected, one quadrant received ultrasonic scaling only, another quadrant received ultrasonic scaling and CO2 laser irradiation, the other quadrant received CO2 laser irradiation only. Clinical parameters measured at baseline, 1 weeks, 2weeks, 4weeks and 8weeks RESULT: Pocket probing depth and clinical attachment level were not changed during study period. Gingival index of all group were improved after treatment. At 1 weeks after treatment, Gingival index of ultrasonic scaling group was only significantly different compared to control group. At 2 weeks after treatment, gingival index of all experimental group were significantly different compared to control group. At 4 and 8 weeks after treatment, gingival index of all group were increased, but experimental group were lower than control group. Sulcus bleeding index was similar to the results of gingival index. At 1 weeks after treatment, all experimental group were significantly different compared to control group and it maintained during study. At 2 weeks after treatment, sulcus bleeding index of all group were lowest during study. Gingival crevicular fluid were measured with Periotron(R) 8000(Oraflow(R) , Inc. USA). At baseline, all group were showed moderately severe condition. At 1 week after treatment, laser treatment only group was reduced quantity of gingival crevicular fluid mostly, and all group were reduced quantity of gingival crevicular fluid. At 2 weeks after treatment, all group were healty state. At 4 and 8 weeks after treament, all group were showed recurrent of inflammation, and control group was the most significantly increased. CONCLUSION: This study showed that the effects of CO2 laser treatment were similar to conventional ultrasonic scaling and this result remained longer than plaque control only. These results suggest possibility of CO2 laser treatment for altered periodontal therapy.
