The bone loss and furcation involvement associated with teeth 36 and 46 are most likely due to caries and endodontic European Archives of Paediatric Dentistry 12 (Issue 1).
If, in the clinical examination, the dental hygienist detects furcation involvement, early on those furcation involvements need to be addressed or the option given of regeneration because we know that the earlier you address the furcation involvement with regeneration, the more successful the outcome," Clem continued.
The Naber's probe or the Furcation probe is a blunt ended instrument that is used buccally and lingually on the periodontal structure to locate possible furcation involvement.
Furcation involvement indicates a serious periodontal condition that if detected early is treatable with guided tissue regeneration.
Frequently, the areas that are most vulnerable to furcation involvement (the posterior areas of the mouth) are difficult to access.
Furcation involvement seriously compromises the future prognosis of the tooth.
This includes the medical and dental history, radiographic evaluation and periodontal assessment (probing, mobility, furcation involvement, gingival findings).
15) Generally, such clinical parameters include probing depth (PD), bleeding on probing (BOP), clinical attachment level (CAL), degree of furcation involvement, extent of gingival recession, tooth mobility, and plaque score.
17) However, with respect to a functional PTP for the general dental practice, only the following principal diagnostic criteria can be addressed: age, PD, CAL, BOP, tooth mobility, furcation involvement, and percentage of radiographic bone loss.
Simply put, a Grade 1 furcation involvement is incipient bone loss only; a Grade 2 is partial loss of bone producing a cul-de-sac; a Grade 3 is total bone loss with through-and-through opening of the furcation; and a Grade 4 is similar to a Grade 3, but with gingival recession that visually exposes the furcation opening.
The patient had periodontitis gravis characterized by a horizontal loss of supporting tissue by more than 1/3rd of root length with bleeding on probing, furcation involvements of the multi-rooted teeth and/or angular bony defects.
Diseased and at-risk teeth are described as those with caries extending into the pulp chamber, those with periapical lesions, periodontal pockets over 4-5 mm, furcation involvements of Grade 2 and mobility of Grade 2 or more.
