For each sampling point the average population exposed to noise was also estimated. The results show that the measured noise levels in all studied points ranged from 72 dBA to 88.8 dBA with a mean of 79.9 ± 2.3 dBA when generators are in use and from 59 dBA to 76.6 dBA (mean of 67.3 ± 2.5 dBA) when generators are not in use.

KEY FINDINGS - Porcelain-Fused-to-Metal Crowns …

The 5-year survival of porcelain-fused-to-metal crowns ranged from 95.7% to 97.6%. The 5-year survival of all-ceramic crowns ranged from 90.7% to 96.6%. All-ceramic crowns made out of leucite or lithium-disilie, densely sintered alumina, glass-infiltrated alumina, and densely sintered zirconia exhibit similar 5-year survival rates as metal-ceramic crowns.
