Aim: To evaluate the solvency of chloroform and eucalyptol for gutta percha removal in re-treatment. MethodologyA total of 40 extracted human maxillary single rooted teeth were selected. Canal preparation was carried out by the sequential use of Kfiles up to size 30 at working length and then divided into one control group(n=10)that is group I and three experimental groups II,III,IV (n=10 each)...

Chloroform and eucalyptol are widely used in clinical dentistry as gutta-percha solvents. However, these compounds may represent a hazard to human health, especially by causing injury to genetic apparatus and/or inducing cellular death. In this study, the genotoxic and cytotoxic potentials associated with exposure to chloroform and eucalyptol were assessed on mouse lymphoma cells in vitro by th...

The aim of this research was to determine the chemical constituents and bioactivity of the essential oil derived from Alpinia galanga (L.) Willd. rhizomes against the cigarette beetle Lasioderma serricorne (F.) (Coleoptera Anobiidae) adults. The essential oil of A. galanga obtained by hydrodistillation was investigated by gas chromatography-mass spectrometry (GC-MS). The main components of the ...

Odor stimuli presented to one nostril can only be localised if they additionally activate the trigeminal nerve's chemosensitive fibers. In this study we aimed to investigate characteristics in the localisation of unilateral trigeminal, olfactory and somatosensory nasal stimuli. We compared the ability of healthy young subjects to localise monorhinally presented (a) pure olfactory stimuli (pheny...

Citral, eucalyptol, and linalool are widely used as flavorings, fragrances, and cosmetics. Here, we examined their effects on electrophysiological and binding properties of human 5-HT3 receptors expressed in Xenopus oocytes and human embryonic kidney 293 cells, respectively. Data were analyzed using nonlinear mixed-effects modeling to account for random variance in the peak current response bet...

The purpose of this study was to investigate the influence of gutta-percha solvents on the bond strength of fiberglass post to root canal dentin. Forty bovine incisors were decoronated, prepared, filled, and randomly distributed into four groups (n = 10) according to the gutta-percha solvent used: control, xylene, eucalyptol and orange oil. After root canal treatment, the posts were cemented in...

OBJECTIVES This study aimed to assess the effect of chloroform, eucalyptol and orange oil solvents on the microhardness of human root dentin. MATERIALS AND METHODS Sixty-eight single-rooted single-canal extracted human premolar teeth were used. Tooth crowns were separated from the roots at the cementoenamel junction (CEJ). Roots were buccolingually sectioned into mesial and distal halves. Spe...

The aim of this study was to develop novel transdermal films of ondansetron HCl with high molecular weight chitosan as matrix polymer and 2-(2-ethoxy-ethoxy) ethanol (Transcutol®) as plasticizer. In this context, firstly the physicochemical properties of gels used to formulate transdermal films were characterized and, physicochemical properties and bioadhesiveness of the transdermal films prepa...

PURPOSE Solvents may be used to remove the filling materials. The purpose of this in vitro study was to evaluate and compare the efficacy of formulated orange oil, orange oil and formulated eucalyptol in dissolving F3 ProTaper Universal Gutta-percha points. MATERIAL AND METHODS 200 samples were used and divided into four groups, further divided in fifty samples for each solvent. The samples w...
