Abstract Aim The aim of this clinical study was to compare the fracture resistance, marginal adaptation, and rate of recurrent caries of bonded and nonbonded amalgam restorations in endodontically treated premolar teeth. Methods and Materials A total of 36 patients with endodontically treated maxillary first or second premolars were selected and divided into three groups. The treatments in all groups consisted of lingual cusp coverage and cementation of a prefabricated intracanal post (No. 2 long, Dentatus USA, New York, NY, USA). One type of cavity liner was used for each group as follows: copal varnish (Group A), Amalgambond Plus (Group B), and Scotchbond Multi-Purpose (Group C). The teeth were then restored with Cinalux high-copper spherical amalgam (Cinalux, Sh. Dr Faghihi Dental Co., Tehran, Iran). After one year, fracture resistance, marginal adaptation, and secondary caries were evaluated. Fischer's exact test was used for statistical analysis using a 0.05 percent significance level. Results There was no significant difference among groups with respect to fracture resistance (p=0.49). However, significant differences in marginal adaptation existed among the three groups (p=0.02) and no recurrent caries were found in any of the restored teeth. Conclusion Bonding amalgam restorations using Amalgambond Plus and Scotchbond Multi-Purpose Plus did not improve the fracture resistance or affect the resistance to secondary caries in endodontically treated premolar teeth. However, the teeth in both these bonded groups showed significant improvement in marginal adaptation compared with restorations placed with copal varnish (p=0.02). Clinical Significance Amalgambond Plus or Scotchbond Multi-Purpose adhesive resins significantly improved marginal adaptation of amalgam compared with copal varnish, but did not enhance fracture resistance or affect the prevention of secondary caries.

Objective: To evaluate fracture resistance and survival rate of IPS Empress CAD versus Polished Celtra Duo ceramic laminate veneers. Material and Methods: Thirty-six ceramic laminate veneers were fabricated for maxillary anterior teeth. The patients were divided into two groups according to the material Group 1(control group) fabricated from IPS Empress CAD laminate veneers and group 2(intervention group) fabricated from Polished Celtra Duo laminate veneers. Standardized the same preparation with butt joint design and chamfer finish line located supra gingival were performed for all the teeth. The fabrication of the veneers was performed using Cad\Cam (Ceramill motion) machine, with software (Exocad). The veneers surfaces were treated and silanated according to the manufacture instruction of each ceramic and enamel surfaces were etched where total etch adhesive protocol was obeyed using BISCO. Follow up sessions were done every two months up to one year for each patient using dental probe and operator vision to evaluate the fracture, survival rate, marginal adaptation, sensitivity and caries. according to USPHS criteria (United States Public Health Service). This was performed by an experienced, blinded investigator. Results: Fracture resistance, marginal adaptation, retention, caries and sensitivity were evaluated according to the criteria of USPHS and we found there is no significant difference as both groups scaled zero score. Conclusion: Both IPS Empress Cad and Polished Celtra Duo laminate veneers revealed successful clinical performance in terms of fracture resistance, marginal adaptation, retention, and sensitivity after one year follow up period.   Keywords Ceramic laminate veneers; IPS Empress CAD; Celtra DUO; Clinical performance.

Objective: the purpose of this study was to evaluate and compare, gross fracture, patient satisfaction, and marginal adaptation of anterior endocrowns restoring endodontically treated anterior teeth fabricated from IPS e.max press and CERASMART hybrid ceramics. Material and methods: A total of 24 patients were selected to receive an esthetic endocrowns for upper teeth in the esthetic zone (central incisor, lateral and canine).The 24 patients were divided into 2 groups (n=12 each), where Group (1): Control group: Teeth receiving IPS e.max press anterior endocrowns and Group (2): Intervention group: Tooth receiving CERASMART anterior endocrowns . After cementation all patients were recalled after 3, 6, 9, and 12 months. During each recall examination, USPHS criteria were adopted for clinical evaluation to score margin integrity and gross fracture. In addition, questionnaires were used to evaluate patients’ satisfaction and potential postoperative discomfort. Chi-square or Fisher’s Exact test were used to compare between qualitative variables in the two groups. Friedman’s test was used to study the changes by time within each group. The significance level was set at P ? 0.05. Results: Regarding gross fracture and marginal integrity, there was no statistically significant difference at any time interval between IPS e.max press and CERASMART endocrowns. All the patients were satisfied with their restorations till the end of the follow up period. Conclusions: CERASMART anterior endocrowns provided a promising treatment modality compared to ips press anterior endocrowns.

Abstract Background Evidence in literature about the best reconstructive approach after melanoma resection is controversial, with some authors advocating that tissue rearrangement flap techniques might hinder the early detection of local relapses. The aim of the present study is to evaluate oncological, aesthetic, and functional outcomes following melanoma reconstruction using pedicled perforator-based flaps. Methods The authors reviewed all patients affected by melanoma treated during a 6-year period. Demographic data, tumor characteristics, and operative variables were evaluated. Locoregional recurrence was assessed with clinical and radiological follow-up. One-year postoperatively patients rated on a 5-point Likert scale the aesthetic and functional outcomes of the procedure. Three blind observers examined preoperative and 1-year postoperative photographs and rated the aesthetic outcome of the reconstructive procedure. Results One-hundred sixty-five patients were treated with wide excision and delayed reconstruction, including pedicled perforator-based flaps in 70 patients (group A) and primary closure in 95 patients (group B). Mean Breslow thickness was 2.972 and 2.189 mm in group A and B, respectively. There was no statistically significant difference in locoregional recurrence (chi-squared test, p = 0.8333; Fisher's exact test, p > 0.9999) between the two groups. Group A reported a higher satisfaction with both the aesthetic (mean rating 4.390 in group A and 4.094 in group B) and functional (mean rating 4.732 in group A and 4.170 in group B) outcomes of the procedure, the latter being statistically significant (p = 0.0006). Conclusion This series suggests that pedicled perforator-based flaps provide optimal aesthetic and functional outcomes in melanoma reconstruction without impairing the locoregional control of the disease.

ABSTRACT Objectives: To observe the degree of correction and postoperative evolution of the spinopelvic parameters in patients with sagittal imbalance submitted to 3-column osteotomies. Methods: Retrospective analysis of 20 cases of 3-column osteotomies in patients with evident sagittal imbalance and minimum follow-up of one year, computing evolution of radiological data as a function of time, complications and reinterventions, and classification into subgroups by preoperative spinopelvic measures and complications. The variation of measures, quantitative and categorical variables, and differences between groups were evaluated using the Wilcoxon, Spearman, Fischer’s exact test, Kruskal-Wallis and Mann-Whitney tests. Results: There was improvement of all the sagittal parameters, ideal correction in 55% of the cases and maintained until the end of the follow-up in 40% of the cases. No correlation was found between obtaining optimal correction and data or preoperative measurements. Clinical and infectious complications did not affect the maintenance of the correction. The most common mechanical complications were pseudoarthrosis-related rod fracture at osteotomy (30%) and failures at the lower fixation level (15%). There was no significant difference in the maintenance of the correction between the groups with and without mechanical complications treated. In the untreated mechanical complications there was a significantly higher radiological worsening (p<0.05) in the maintenance parameters of the curve correction (loss of 27.5 ± 14.39o vs. 3.69 ± 3.68o) and increased pelvic tilt (PT) (increase of 12.25 ± 7.27o vs. 1.13 ± 1.93o). Conclusion: The perfect correction was obtained in 55% of cases and the significant loss of correction occurred only in cases of untreated mechanical complications.

SUMMARY Replacement of dental restorations has been the traditional treatment for restorations that are defective. In this five-year randomized clinical trial, restorations with localized marginal defects were treated with sealants. Thirty-two patients (mean age, 26.8 years) with 126 Class I and Class II restorations with defective margins (amalgam n=69 and resin-based composite n=57) were recruited. Treatment was seal with pit and fissure sealant on localized marginal defects (group A: n=43) and was compared with total restoration replacement (group B: n=40) and untreated restorations (group C: n=43) as negative and positive controls. Restorations were assessed by two examiners using the modified US Public Health Service criteria, observing five clinical parameters: marginal adaptation, roughness, marginal stain, teeth sensitivity, and secondary caries at baseline and at five years after treatment. At the five-year recall examination, 23 patients with 90 restorations (71.4% recall rate) were examined. A significant improvement was observed in the marginal adaptation of the restorations in group A compared with group B. None of the treated group showed trends to downgrade in any parameter. Tooth sensitivity and secondary caries showed a low frequency in all groups. No significant difference in marginal adaptation of the restorations was found between amalgam and resin-based composite restorations (p=0.191). This study demonstrated that marginal sealing of restorations is a minimally invasive treatment that may be used instead of the replacement of restorations with localized marginal defects.

The Relationship

Introduction: Uterine prolapse is a gynecological problem that women often experience with a prevalence of 50% and is predicted that the next 30 years will increase by 45% as life expectancy increases. Increased degrees of uterine prolapse have an impact on the deterioration of women's quality of life. The uterine prolapse is influenced by several mutually supportive factors. The purpose of this study was to analyze the relationship between these factors to the degree of uterine prolapse.Methods: This research is an observational analytic research with cross sectional approach. The number of samples were 65 patients with uterine prolapse at Policlinic Gynecology RSUD Dr. Soetomo Surabaya from 2015-2017. Sampling was done by consecutive sampling. To find out the significant level, the collected data will be tested with Fisher Exact Test statistic at significance level α = 0,05.Results: The result showed that there was significant difference between degree of uterine prolapse with age factor (p = 0,016) and obesity (p = 0,041). As for the parity factor (p = 0.508) there was no significant difference between the parity factor and the degree of uterine prolapse.Discussion: Age is a major factor affecting the degree of uterine prolapse, weakening of pelvic floor tissue and muscle in elderly women is the main cause. While on the obesity factor, there is no data to support that obesity is related to the degree of uterine prolapse because the trend indicates that the majority of patients are not obese. In contrast the parity factor, although according to the statistical test there is no difference to the degree of uterine prolapse, the trend shows that parity leads to increased incidence of uterine prolapse itself.Conclusion: Age is a factor that affects the degree of uterine prolapse.

Abstract In this study one-year clinical results of high-viscosity glass ionomer cement (GIC) (Fuji IX, A3, GC, Japan) were determined in class I and class II restorations in 68 primary molars with occlusal or approximal caries. Following caries removal and cavity preparation, the teeth were restored with Fuji IX. The restorations were evaluated according to the U.S. Public Health Service's (USPHS) criteria at the end of one year. Statistical analyses of the data obtained were analyzed using the X2 test. The evaluations showed no statistically significant difference between class I and class II restorations in terms of the color mismatch, anatomic form, marginal adaptation, and secondary caries (P>0.05), but they were statistically significant with regard to cavosurface marginal discoloration (P<0.05). At the end of one year, the success rate of the class I and class II restorations of the primary molars restored with Fuji IX was 94%. Citation Yilmaz Y, Eyuboglu Ö, Kocogullari ME, Belduz M.

Abstract Background Endodontically treated immature teeth which are restored with cast metal posts are of the most susceptible teeth to fracture. An apical plug is usually used as root end filling in order to seal the wide apical foramen. The current study was performed to evaluate the effect of different apical plug materials (MTA and Calcium enriched mixture cement) at varied thicknesses on fracture resistance of teeth restored with cast metal posts. Methods A total of 40 extracted intact single-rooted human mandibular premolars (removed for orthodontic reasons) were used in the study. The coronal part of each tooth was removed and root canal preparation was performed. A size 4 Gates Glidden drill was used to enlarge the canal and was passed through the apical foramen in order to simulate an immature apex. Samples were randomly divided into 5 groups (n = 8) according to apical plug (control group: No plug, group MTA5: 5 mm MTA plug, group CEM5: 5 mm CEM plug, group MTA3: 3 mm MTA plug, group CEM3: 3 mm CEM plug). Post-space preparations were performed and cast metal post-and-cores were fabricated and cemented. Fracture resistance was assessed using a universal testing machine. Fracture thresholds were recorded and data were analyzed using One-way ANOVA and Dunnett’s T3 tests with significance level at P value < 0.05. Results The analysis showed a significant difference of fracture resistance between groups (P value < 0.05). The mean fracture resistance of samples in control group was significantly lower than MTA5 (P value = 0.003). There was no significant difference between other groups (P value > 0.05). Conclusions Within the limits of this study, the evidence indicated that placement of a 5 mm MTA apical plug increased the fracture resistance in simulated immature teeth which are restored with cast metal posts, compared to control group (gutta-percha and sealer). While the results were not as promising for a 3 mm MTA apical plug or either 3 or 5 mm CEM apical plug.
