Perhaps you should try some spelling variations:
based processes » based process (Expand search), and processes (Expand search)
decrease tooth » decrease with (Expand search), decrease food (Expand search), decrease costs (Expand search)
pythons python » python python (Expand search), pitons python (Expand search), piton python (Expand search)
tooth disease » mouth disease (Expand search)
disease based » disease caused (Expand search), disease case (Expand search), diseases caused (Expand search)
c pythons » _ python (Expand search)
python c » python _ (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 based processes ) OR ( python c pythons python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease tooth disease based processes ) OR ( python c pythons python programming ))*.
