In Vivo study of an intracanal dressing of calcium hydroxide/chlorhexidine in necrotic primary teeth

AIM:To evaluate the clinical and radiographic success of endodontic treatment in human primary teeth with necrotic pulp with and without radiographically visible furcal/periapical lesion treated with a calcium hydroxide (CH) and chlorhexidine (CHX) intracanal dressing. The tested hypothesis was that there is no difference in the clinical and radiographic success in primary teeth medicated with CH pastes prepared with polyethylene glycol (PEG) or CHX.METHODS:Thirty-two teeth with necrotic pulp were used in this randomized clinical study: 12 without and 20 with lesion. Canals were prepared and medicated with CH pastes with polyethylene glycol (CH/PEG) (n=16) or 2% CHX gel (CH/CHX) (n=16). Definitive filling was done after 30 days. The teeth were clinically and radiographically examined during 12 months to determine the success of the endodontic therapy. Data from clinical and radiographic examination of the initial condition and 12 months after treatment were compared using the Z test (α = 0.05).RESULTS:There was no significant difference (p>0.05) in the success rate of teeth with and without lesion medicated with CH/PEG or CH/CHX. No significant difference (p>0.05) was found between the pastes regardless of the presence of lesion.CONCLUSIONS:Combination of CHX and CH was not more effective than the CH/PEG paste, as similar clinical and radiographic success rate was observed in teeth medicated with either type of intracanal dressing.

Avaliação dos potenciais fitotóxico e citotóxico de pyrostegia venusta (Ker Gawl.) miers (bignoniaceae)

Pyrostegia venusta (Ker-Gawl.) Miers (Bignoniaceae) is a species with a wide distribution in nearly all of Southern and Southeastern Brazil, has long been used in folk medicine and is considered an invasive plant. The phytotoxic potential of a hydroalcoholic extract of the flowers of P. venusta was evaluated by the germination (pre and post-emergence) and the phytotoxicity bioassays (mitotic index) on the test plant Lactuca sativa (Asteraceae) (lettuce). A phytochemical screening was performed to identify the components of the floral extract. Different concentrations of the extract caused changes in the germination parameters, the root length and the mitotic index. The phytochemical screening indicated the presence of substances such as terpenes, sterols, flavonoids, tannins and saponins, which are compounds that may be associated directly with the results of cytotoxicity and phytotoxicity observed. P. venusta has allelochemical components capable of impairing the germination and root growth of lettuce.

Efeitos da Isradipina (LOMIR). Agente inibidor de canais de cálcio, no processo de reparo em feridas de extração dental: estudo histológico em ratos

In order to make a histological evaluation of the dental alveolus wound healing in presence of the Isradipine (Lomir/Sandoz Pharma), the new calcium channels blockers, forthy-eight albino rats were utilized. These animals were divided in two groups. The animals of group I were considered as control; in group II, after the dental extractions the rats received intraperitonial injections of 2,5 mg/Kg of isradipine, administered a single dose. From each group of animals were sacrificed at 3, 7, 14 and 21 post-operative days. The pieces were fixed, descalcified and embedded in paraffin. The blocks thus obtained were cut at 6 micrometers thick and sections were stained with hematoxylin and eosin for morphological study. According to the results obtained i t was verified that the treated animals did not alter of wound healing after dental extractions
