Review[A clinical and epidemiological study of Tori mandibularis].
This is a study aiming at: a) reviewing the information found in the relevant literature as regards the etiology, incidence, distribution, implication and management of the tori mandibularis, b) evaluating the incidence, location and morphology of this bony mass in a sample of Greek population and c) comparing the findings with those of other investigators. The material consisted of 357 patients, from 20 years old and onwards, who had consecutively visited the Clinic of Removable Prosthodontics for some problem. After clinical examination and tabulation of the findings, the following conclusions were drawn: a) the etiology of appearance of tori mandibularis remains unknown; b) in our sample, 12.8% had this condition; c) the incidence was higher in men (60.4%) than in women (39.5%); d) in our sample, the higher percentage of individuals showing the condition originated from Thraci (Northern Greece) while the lower came from Hepiros; e) No indication of a heredity factor was found; f) this condition is more often bilateral than unilateral and g) the torus mandibularis was extending from the canine to the area of the first premolar in 54.4% of the cases.

[Arterial pressure variation following an intravenous and submucous injection of local anaesthetic solutions with vasoconstrictor].
This paper deals with the control, registration and statistical evaluation of blood pressure variations (systolic, diastolic and average) after an i.v. and submucous injection of fixed quantity local anaesthetic solutions (0.05 ml) in white hamsters. The solutions used were: lidocaine 2% with adrenaline 1/80,000, lidocaine 3% with noradrenaline 1/25,000. The intravenous injection of all three local anaesthetic solutions has caused an increase of the arterial pressure parameters which was statistically significant (P less than 0.01). ⋯ On the contrary, the submucous injection of lidocaine 3% solution with noradrenaline 1/25,000 has led to an increase of the arterial pressure which is statistically important (P less than 0.05). The research results have led to the following conclusions: 1) Intravascular injection of local anaesthetics with adrenaline or noradrenaline has immediate negative consequences on the circulatory system, a fact which renders necessary a test respiration prior to any stem anaesthesia. 2) The submucous injection of lidocaine solutions with adrenaline or noradrenaline 1/80,000 may be described as harmless with respect to cardiovascular toxicity, and 3) The 3% lidocaine solution with noradrenaline 1/25,000 has proved to be capable of producing significant increase of the arterial pressure following a submucous injection. Anaesthetic solutions with 1/25,000 noradrenaline concentration should not be used, while they must be considered as extremely hazardous for patients with cardiovascular problems.
