ABSTRACT Objectives The aim of this study was to evaluate the effect of a motivation and practical skills development methods on the oral hygiene of orphans. Material and Methods Sixty eight orphans aged between 7 and 17 years from two orphanages in Kaunas were divided into two groups: practical application group and motivation group. Children were clinically examined by determining their oral hygiene status using Silness-Löe plaque index. Questionnaire was used to estimate the oral hygiene knowledge and practices at baseline and after 3 months. Statistical analysis included: Chi-square test (χ2), Fisher‘s exact test, Student‘s t-test, nonparametric Mann-Whitney test, Spearman’s rho correlation coefficient and Kappa coefficient. Results All children had a plaque on at least one tooth in both groups: motivation 1.14 (SD 0.51), practical application 1.08 (SD 0.4) (P = 0.58). Girls in both groups showed significantly better oral hygiene than boys (P < 0.001). After 3 months educational program oral hygiene status improved in both groups significantly 0.4 (SD 0.35) (P < 0.001). Significantly better oral hygiene was determined in practical application group 0.19 (SD 0.27) in comparison with motivation group 0.55 (SD 0.32) (P < 0.001). By comparing results of first and second questionnaire surveys on use of soft drinks, the statistically significant decline of their use was in both groups (P = 0.004). Conclusions Educational programs are effective in improving oral hygiene, especially when they’re based on practical skills training.

ABSTRACT Objectives To compare the efficacy of Reciproc® (VDW GmbH) and ProFile® (Dentsply Maillefer) instruments at removing gutta-percha from straight and curved root canals ex vivo filled using the cold lateral condensation and GuttaMaster® (VDW GmbH) techniques. Material and Methods Forty mesial roots of mandibular molars with two curved canals and 80 single-rooted teeth with straight root canals, a total of 160 root canals, were randomly assigned to eight groups (canals per group = 20) according to filling technique, retreatment instrument and root canal curvature as follows: Group I, cold lateral condensation/ProFile®/straight; Group II, cold lateral condensation/ProFile®/curved; Group III, cold lateral condensation/Reciproc®/straight; Group IV, cold lateral condensation/Reciproc®/curved; Group V, GuttaMaster®/ProFile®/straight; Group VI, GuttaMaster®/ProFile®/curved; Group VII, GuttaMaster®/Reciproc®/straight; and Group VIII, GuttaMaster®/Reciproc®/curved. The following data were recorded: procedural errors, retreatment duration and canal wall cleanliness. Means and standard deviations were calculated and analysed using the Kruskal-Wallis test, one-way analysis of variance and Tukey’s test (P < 0.05). Results Reciproc® instruments were significantly faster than ProFile® instruments at removing GuttaMaster® from both straight (P = 0.0001) and curved (P = 0.0003) root canals. Reciproc® were statistically more effective than ProFile® instruments in removing GuttaMaster® from straight root canals (P = 0.021). Regardless of filling technique or retreatment instrument, gutta-percha was removed more rapidly from curved than from straight root canals (P = 0.0001). Conclusions Neither system completely removed filling material from the root canals. Compared with ProFile® instruments, Reciproc® instruments removed GuttaMaster® filling material from straight and curved root canals more rapidly.

ABSTRACT Objectives Free fibula flap remains the flap of choice for reconstruction of mandibular defects. If free fibula flap is not possible, the subscapular system of flaps is a valid option. In this study, we evaluated the possibility of dental implant placement in patients receiving a scapular free flap for oromandibular reconstruction. Material and Methods We retrospectively reviewed 10 patients undergoing mandible reconstruction with a subscapular system free-tissue (lateral border of the scapula) transfer at the University Hospital Zürich between January 1, 2010 and January 1, 2013. Bone density in cortical and cancellous bone was measured in Hounsfield units (HU). Changes of bone density, height and width were analysed using IBM SPSS Statistics 22. Comparisons of bone dimensions as well as bone density were performed using a chi-square test. Results Ten patients were included. Implantation was conducted in 50%. However, all patients could have received dental implants considering bone stock. Loss of bone height and width were significant (P < 0.001). There was a statistical significant increase in bone density in cortical (P < 0.001) and cancellous (P = 0.004) bone. Conclusions Dental implants are possible after scapular free flap reconstruction of oromandibular defects. Bone height and width were reduced, while bone density increased with time.
