Perhaps you should try some spelling variations:
decrease tooth » decrease with (Expand search), decrease food (Expand search), decrease costs (Expand search)
tooth disease » mouth disease (Expand search)
python python » pythons python (Expand search), piton python (Expand search), pitons python (Expand search)
disease loss » disease cross (Expand search), disease long (Expand search), disease across (Expand search)
loss process » cmos process (Expand search)
python dados » python data (Expand search), python redes (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease tooth disease loss process ) OR ( python dados python python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease tooth disease loss process ) OR ( python dados python python programming ))*.
