amyl acetate/dental caries

Complaints about unpleasant environmental odorants, both outdoor and indoor, are increasingly being reported. The main complaints of health symptoms from environmental odorants are eye, nose and throat irritation, headache and drowsiness. Complaints may arise from the stimulation of olfactory

OBJECTIVE To evaluate the influence of an epoxy resin-based sealer on the bond strength of adhesive resins to dentin and the cleaning efficacy of different solvents in removing sealer residues. METHODS The occlusal enamel of 25 freshly extracted human third molars without caries were removed to

Amyl acetate stimulation of the neuroepithelial cells of the olfactory mucosa induced significant responses in the olfactory bulb and modulated the spontaneous electrical activity of the hypoglossal neurons localized in the mediocaudal part of the XIIth nucleus. Olfactory stimulation induced several

Regeneration of olfactory receptor neurones after bulbectomy can lead to formation of extrabulbar synapses, the functional significance of which remains controversial. Adult hooded rats (n = 27) were bilaterally bulbectomized under pentobarbital anaesthesia. Small pieces of brain tissues (1-2 mm3;

On the day before birth, mouse fetuses were tested for their behavioral responses to iso-amyl acetate and iso-valeric acid delivered into the nasal cavity in liquid phase. Pilot studies established that most subjects responded to most concentrations used with an increase in total behaviors and

Following inhalation, manganese travels along the olfactory nerve from the olfactory epithelium (OE) to the olfactory bulb (OB). Occupational exposure to inhaled manganese is associated with changes in olfactory function. This pilot study evaluated two related hypotheses: (a) intranasal manganese

One-day old domestic chicks (Gallus gallus domesticus) show concentration-dependent behavioural responses to olfactory cues. In the present study we investigated the lateralized olfactory responses of 1-day-old chicks to the odours of eugenol and iso-amyl acetate. In experiment 1 different

The objectives of this study were to determine: (1) the frequency and distribution of carbonic anhydrase (CA) activity in the bullfrog nasal cavities, and (2) whether inhibition of nasal CA affects the olfactory receptor response to CO2 or other odorants. It was found, using Hansson's staining
