Furcation involvement refers to the situation where the '''bone between the roots of multirooted teeth is destroyed''' due to [[periodontitis]] <font color="red">(Fig. 6.4)</font color>. The furcation sites of multirooted teeth should be examined with a ''[[Periodontal Probe|periodontal probe]]''. The grading of furcation involvement:
Furcation involvement refers to the situation where the '''bone between the roots of multirooted teeth is destroyed''' due to [[periodontitis]] <font color="red">(Fig. 6.4)</font color>. The furcation sites of multirooted teeth should be examined with either a ''[[Periodontal Probe|periodontal probe]]'' or ''[[Dental Explorer|dental explorer]]''. Furcation involvement is graded as follows:
<br>
<br>
:'''Grade 0''' - No furcation involvement
:'''Grade 0''' - No furcation involvement
:'''Grade 1''' - Initial furcation involvement: the furcation can be felt with the [[Periodontal Probe|probe]]/[[Dental Explorer|explorer]], but horizontal tissue destruction is less than 1/3 of the horizontal width of the furcation
:'''Grade 1''' - Initial furcation involvement: the furcation can be felt with the [[Periodontal Probe|probe]]/[[Dental Explorer|explorer]], but horizontal tissue destruction is less than 1/3 of the horizontal width of the furcation
:'''Grade 2''' - Partial furcation involvement: it is possible to explore the furcation but the probe/explorer cannot be passed through it from buccal to palatal/lingual; horizontal tissue destruction is more than 1/3 of the horizontal width of the furcation
:'''Grade 2''' - Partial furcation involvement: it is possible to explore the furcation but the probe/explorer cannot be passed through it from buccal to palatal/lingual; horizontal tissue destruction is more than 1/3 of the horizontal width of the furcation
:'''Grade 3''' - Total furcation involvement: the probe/explorer can be passed through the furcation from buccal to palatal/lingual
:'''Grade 3''' - Total furcation involvement: the probe/explorer can be passed through the furcation from the buccal to palatal/lingual aspect of the mouth
