Background: Repair of bone damage represents a fundamental issue in the treatment of periodontitis. The important indicator employed to monitor the bone damage repair process is the number of osteoblast cells. Achatina Fulica snail mucin (SM) contains glycosaminoglycans which have the potential to increase their number. However, the use of SM in dentistry remains limited. Purpose: To determine and prove the effect of SM gel in increasing the number of osteoblasts in rat models suffering from periodontitis. Methods: This study used 36 rat models divided into three groups, namely; a treatment group (T: 20% snail mucin gel, n = 12), a positive-control group (P: hyaluronic acid gel, n = 12) and a negative-control group (N: CMC-Na gel, n = 12). 0.2 ml of all material was applied to a pocket by means of a tuberculin syringe once a day for 14 days. Histologic observations using Haematoxylin-Eosin staining were carried out on days 3, 5, 7 and 14. Data was analyzed by two-way ANOVA followed by a post-hoc LSD. Results: A significant difference existed between the number of osteoblasts in the test groups. The highest number of osteoblasts observed was consistently that in the treatment group. Conclusion: The application of 20% snail mucin gel was effective in enhancing the number of osteoblasts in rats suffering from periodontitis.

The aim of this study was to evaluate the sealing ability of three different canal filling techniques. Sixty-four roots of extracted human maxillary anterior teeth were prepared using ProTaper® rotary instruments. The specimens were then randomly divided into 3 experimental groups (n=16) and 2 control groups (n=8). The root canals were filled using cold lateral compaction (CLC group), continuous wave condensation technique using the Elements Obturation Unit® (EOU group), and ProTaper obturators (PT group). For the negative control group, 8 roots were filled using lateral compaction as in the CLC group, and the teeth were covered twice with a layer of nail varnish (NCG group). Another 8 roots were filled using lateral compaction, but without sealer, and these were used as the positive control (PCG group). A glucose leakage model was used for quantitative evaluation of microleakage for 24 hours and 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 weeks. No significant difference in the cumulative amount of leakage was found between the three experimental groups at all observation times. The lateral condensation of cold gutta-percha can guarantee a similar seal of canal fillings as can be achieved by using thermal methods, in the round canals.

Aim. The study aimed at evaluating the incidence of dentinal defects after root canal retreatment with ProTaper Universal retreatment (PTUR) and XP-endo Shaper and Finisher R (XP). Materials and Methods. Sixty extracted single-rooted human premolars were selected and divided into 4 groups of 15 teeth each. In the negative control group, the teeth were left unprepared. In the positive control group, the teeth were prepared with ProTaper Next and obturated with no further retreatment. In the PTUR and XP groups, the teeth were prepared and obturated followed by removal of the filling material at body temperature using PTUR and XP instruments, respectively. The roots were then sectioned at 3, 6, and 9 mm from the apex and observed under a digital microscope to detect defects. Results. PTUR group showed significantly higher ( p value <0.05) incidence of defects than the other groups. Comparison of no defects versus defects between groups in different areas of root canals demonstrated significant difference among the groups in the apical and cervical regions. Conclusion. Within the limitations of the present study, PTUR files created significantly more dentinal defects than XP files, with most of those defects at the cervical and apical areas of the root canals.
