OBJECTIVES The aim of the present study was to evaluate DNA damage (micronucleus) and cellular death (pyknosis, karyolysis and karyorrhexis) in exfoliated buccal mucosa cells from adults following cone beam CT exposure. METHODS A total of 19 healthy adults (10 men and 9 women) submitted to cone beam CT were included. RESULTS No significant statistically… (More)
A wound-generated steady electric current was measured by a two-dimensional vibrating probe system in the metatarsal bones of 22 adult frogs (Xenopus laevis) placed in amphibian Ringer. Inward currents were recorded entering a micrometric hole drilled through the cortex at middiaphyseal level. These steady state currents (mean +/- SD 8.50 +/- 2.77… (More)
To provide evidence of active accumulation of K(+) in bone extracellular fluid (BECF), electric currents driven by damaged living metatarsal bones of weanling mice, immersed in physiological media at different [K(+)], in the presence of blockers of the K(+) channels or of the Na(+)-K(+-)ATPase inhibitor, were measured by means of a voltage-sensitive… (More)
Genial tubercles usually are small bony protuberances on the lingual aspect of the mandible symphysis. Conversely, this case shows 3D tomographic reconstruction images of genial tubercles as an oversized projection causing pain and discomfort to the patient.
There has always been concern in determining the relationship between orthodontic tooth movement and the consequent biological costs to the periodontium and tooth root. The possibility of evaluating the tooth and bone morphology by CBCT allows more accurate analysis of qualitative and quantitative aspects of these processes. This paper presents a case… (More)
