ABSTRACT
Dental chromatic space has been the topic for many studies and most of all indicated that dental structures are very versatile from the colour point of view, therefore a proper shade selection is difficult to made. Our study made a comparison between the shades of dental structures of men and women of different ages, the measurements being done in three regions: incisal, middle and cervical. We used a spectrophotometer Spectra-Flash 600 and the PC programme Data-Master version 2.3 for both chromatic determinations and the statistical evaluations. The study proved that there are no major differences between the dental shades of men and women; meanwhile chrome increases with age and from incisal to cervical regions. Also, value increases from incisal to cervical region.

Noise pollution is one of the most important problems of the contemporary world. Dentistry is one of the most affected areas because the activity in a dental practice involves the use of different devices that generate noise. The purpose of our study is to evaluate the sound level in a dental practice with 4 dental units using a complex system, which comprises: a Sound Blaster Live 5.1, a Dual microphone, a PC and special software for the acquisition and data analysis. The sound level detected by us is similar with the data from the international literature with some particular aspects and suggests that the dental practice is a noise polluted environment although most of the sound levels are beneath the damaging noise level for the human ear (85 dB).
