Background: The process of wound healing is influenced by various factors such as age, hormones, and wound care. Wound care is done to accelerate wound healing which can be done by various methods, one of them is traditional care. Traditional wound care can use medicinal plants. Rhodomyrtus tomentosa is a medicinal plant that has an antioxidant, anti-inflammatory, antitumor and antibacterial content. Thus this study aims to evaluate the effectiveness of the antiseptic solution of the Rodhomyrtus tomentosa leaf extract on wound healing in male Wistar rats. Method: this research is pure experimental research with post test only control group design. Thirty male white rats were divided into five groups, namely negative control, positive control, Rhodomyrtus tomentosa leaf extract 15%, 30%, and 60%. Rhodomyrtus tomentosa leaf extraction was carried out by maceration method with 70% ethano solvent. The extraction results are divided into 3 concentrations (15%, 30% and 60%). The wound healing process was evaluated by measuring the length of the wound manually from 0 to 10 days in each group. Meanwhile, the number of fibroblast cells was calculated through hematoxylin eosin (HE) staining and observed using an Olympus CX41 microscope with a 10x magnification and objective lens magnification in 3 fields. Result: There was a significant difference in the reduction in wound length (p =< 0,000) between the five experimental groups (Rhodomyrtus tomentosa leaf extract solution 15%, 30% and 60%, negative control and positive control. Solution of rhodomyrtus tomentosa leaf extract accelerated the increase in the number of fibroblasts compared to the negative control group (p = 0.003), but did not make a difference (p = 0.403) with the positive control group. Rhodomyrtus tomentosa leaf extraction solution had the same microscopic effect on the number of fibroblasts with a positive control group given 0.9% NaCl solution. Conclusion: There was a significant difference in the number of fibroblasts between all groups, but no difference in wound healing length.

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.

This study used 24 male white rats, divided into four groups, negative control group (P0) given placebo, positive control group (P1) given paracetamol dose 250 mg / kg bw for 10 days, P2 given ant nest extract 250 mg / kg bw and paracetamol dose 250 mg / kg bw for 10 days, P3 given ants nest extract 250 mg / kg bw for seven days, then continued by giving paracetamol and ants nest extract with dose 250 mg / kg bw for ten days. After the treatment done, all the rats were dinecropsed. Liver organs were taken and processed for making histopathology preparations. Parameters examined included hemorrhage, congestion, degeneration and necrosis. The data obtained were analyzed statistically by using Kruskal Wallis test followed by Mann Whitney test. Mann Whitney test results for all categories of histopathologic changes in  hemorrhagic, congestion, degeneration, and necrosis between negative control group (P0) and positive control group (P1) were significantly different (P <0.05), between negative control (P0) with P2 and P3 there was no significant difference (P> 0,05). Afterward, between the positive control (P1) and P2 with P3 there was a significant difference (P <0.05). I can be concludedthat the administration of paracetamol dose 250 mg/kg bw for 10 days affects the histopathologic changes of white rat liver. The administration of ant nest plant extracts can reduce the side effects of toxic doses of paracetamol.
