The authors compared four different methods for tooths filling employing cements and gutta-percha by means of stereo and scanning electron microscopy. For this they prepared and filled 32 monoradicular teeth divided in 4 groups of 8 elements and afterwards they made sections at 2, 5, 8 mm from the apex. The thermomechanic condensation techniques showed very good effects. Good performances come using the vertical and lateral condensation techniques when the single cone method produced variable results.
The AA. evaluated the cusps sides inclination variability of about 1,000 subjects. From the data it has been observed a greater vestibular sides inclination (between 38 degrees and 41 degrees) compared to lingual's (between 29 degrees and 32 degrees). For this the AA. suggest the need of some cavity modifications for improving the CSA/AMA ratio during the conservative procedures only when cuspidal sides are more binded.
The authors briefly recall the oral defense factors, particularly the IgAs, and by a clinical research on normal and drugs HIV positive and negative addicts, seek a possible correlation between the above mentioned conditions and the IgAs concentrations. The impossibility in establishing such a correlation and the drugs addicts IgAs/carions incidence ratio's data, emphasize the complexity of the IgAs connected problems.
