Objective To study the impact of the number of functional natural teeth (FNT) and different oral restoration behaviors on well-being of the elderly.Methods The elderly residents of Guangzhou Haizhu District were acted as respondent,WHO-5 Scale was the measurement instrument of well-being.Analysis of covariance was used to correct confounding factors and analyze the corrected data,and then it was compared by LSD Test.Resuits (1) The results of analysis of covariance showed that,average scores on WHO-5 Scale were not all the same among different groups which were divided by different number of FNT or different oral restoration behaviors (Respectively:F=21.547,P<0.001 ; F=141.219,P<0.001).(2) The results of LSD Test showed that,although there were no statistical differences in corrected average scores between group with 5-9 FNT and group with 10-14 FNT (LSD-t=-0.536,P=0.593),differences had statistical senses between other groups(P<0.01).All scores were ordered from the least to the most number of FNT,and they were (11.786±5.270),(15.724±4.036),(15.934±3.957),(18.941±2.616) and (23.390±6.951) respectively.It also showed that,there were no statistical differences in corrected average scores between the perfect oral restoration behavior group,the imperfect oral restoration behavior group and the no oral restoration behavior group(respectively:(23.056±4.772),(20.647±2.660),(14.872±7.313) ; P<0.01).Statistical differences were also found in corrected average scores between the imperfect oral restoration behavior group and the abnormal oral restoration behavior group (respectively:(20.647 ±2.660),(14.565±2.914);LSD-t=13.108,P<0.01).No statistical differences were found in corrected average scores between the no oral restoration behavior group and the abnormal oral restoration behavior group(respectively:(14.872±7.313),(14.565±2.914) ; LSD-t=-0.696,P<0.01).The differences in corrected average scores between the needless oral restoration behavior group and the perfect oral restoration behavior group also showed no statistical significance (respectively:(22.848± 8.068),(23.056± 4.772) ; LSD-t =-0.340,P =0.734).Conclusion Well-being of the elderly may be associated with number of FNT and oral restoration behaviors.

OBJECTIVETo explore the effect of preoperative anxiety level on postoperative pain sensation in partially edentulous patients undergoing surgery for implant denture.
METHODSEighty partially edentulous patients receiving implant denture were examined for preoperative anxiety level using State Trait Anxiety Inventory (STAI) and Modified Dental Anxiety Scale (MDAS) questionnaires before implantation surgery. The Visual Analogue Scale (VAS) and Present Pain Intensity (PPI) Questionnaire were used to assess the pain sensation in patients immediately after the operation. The correlations of preoperative state anxiety, trait anxiety, and dental anxiety with postoperative VAS score were analyzed. According to the assessment results of STAI, the patients were divided into little or no (score range 20-37) anxiety group (L group), moderate (38-44) anxiety group (M group), and high (45-80) anxiety group (H group) to analyze the effect of state anxiety and trait anxiety levels on postoperative pain sensation.
RESULTSSignificantly positive correlations were found between preoperative state anxiety, trait anxiety and dental anxiety among the patients (P<0.01). Postoperative VAS score was positively correlated with trait anxiety score (P<0.01) and differed significantly between different trait anxiety groups (P<0.01). Compared with the patients in M and L groups, those in H group showed a significantly higher VAS score after the operation (P<0.05).
CONCLUSIONThe preoperative trait anxiety level is associated with postoperative pain sensation in partially edentulous patients receiving implant denture, suggesting the necessity of preoperative anxiety intervention in clinical practice.

Objective:
To investigate the clinical effect of concentrated growth factor (CGF) applied in guided bone regeneration (GBR) for severe bone deficiency in the anterior maxilla.
Methods :
Forty patients with bone defects in the anterior maxilla were chosen to be treated with GBR, 20 patients were treated with CGF applied in GBR as the observation group, and the other 20 patients were treated only with GBR as the control group. The evaluation of wound healing was performed after the operation, and bone augmentation was evaluated half a year after the operation.
Results:
The first-stage healing rate of soft tissue wounds in the observation group was 100% and 75% in the control group, and the primary healing rate in the observation group was better than that in the control group (P=0.017). The changes in bone width of the observation group were (3.70 ± 0.28) mm, and those of the control group were (2.96 ± 0.16) mm. The bone augmentation in the observation group was higher than that in the control group (P=0.000).
Conclusion
CGF applied in GBR has a good effect on bone augmentation for severe bone deficiency in the anterior maxilla.

OBJECTIVE:
To evaluate the long-term clinical outcomes of two-stage closed sinus lift for the maxillary sinus with residual bone height (RBH) of 1-3 mm in the posterior maxillary.
METHODS:
Seventy-eight patients with maxillary posterior tooth loss (1 mm≤RBH≤3 mm and alveolar ridge width ≥5 mm) were treated with two-stage closed sinus lift at the Dental Implantation Center of our hospital between March, 2012 and December, 2014. Coral hydroxyapatite powder and 148 implants were implanted. The superstructure was fixed within 6 months after the operation and the patients were followed up for 1-5 years for assessing the patients' satisfaction, postoperative response, stability and survival rates of the implant, soft tissue condition, bone height of maxillary sinus floor elevation and the marginal bone loss.
RESULTS:
Perforation of the maxillary sinus floor occurred in 3 (3.85%) of the cases. Twenty-three (30.67%) patients complained of mild pain, and 52 (69.33%) did not experience headache or fever or reported obvious pain or swelling after the operation. The overall response to the operation was favorable. The ISQ value was 58.39±1.39 immediately after the operation, and increased significantly to 81.88±1.22 at 6 months ( < 0.05). During the healing period and the follow-up, none of the implants fell off, and the implant survival rate was 100%. The peri-implant probing depth and modified sulcus bleeding index at 1 year after sinus lifting were similar to those at 5 years after the operation ( > 0.05), but the sinus floor elevation and marginal bone resorption at the two time points differed significantly ( < 0.05).
CONCLUSIONS
Compared with lateral wall lifting, two-stage close lifting of the maxillary sinus floor is associated with less trauma and less discomfort, and effectively solves the problem of severe alveolar bone height deficiency in the maxillary posterior region to achieve favorable long-term clinical outcomes.
