- Poor root form. - Deep class II or Class III furcation. - 2+mobility or greater.
Assigning prognosis
Hopeless Prognosis: Inadequate attachment to maintain the tooth in health, comfort and function. Extraction is recommended.
would allow proper maintenance, but with difficulty.
Assigning prognosis
Questionable prognosis: One or more of the following:
- Severe attachment loss resulting in a poor crown-to root ratio.
2 Degree of periodontium destruction (Disease Severity)
3 The elimination of local factors: calculus, plaque, occlusal trauma
4 Tooth mobility degree
5 The number of teeth remaining in oral cavity 6 patient cooperation:self-performing plaque

Assigning prognosis
Becker et at (1984) recommended one or more of the following to assign hopeless prognosis:
More than 70% of bone loss. Probing depth >8mm. Class III furcation Mobility grade III. Poor crown –root ratio. History of repeated periodontal abscess formation.
Assigning prognosis
Fair prognosis: Indicates there is a good chance that the teeth can be restored to health and retained, assuming proper maintenance.
Assigning prognosis
The following criteria constitute a good prognosis: - Probing depth 0-3mm. - Less than 10% bone loss. - No furcation. - No pathologic mobility.
control, reevaluation at time 7 environmental and behavioral factors:smoking 8 systemic factors: diabetes 9 age:
Factors to consider when assigning individual tooth prognosis:
1 PD and AL 2 the alveolar bone resorption degree and
types: 3 tooth mobility degree 4 Anatomic factors: short, tapered roots; cervical
enamel projections, root concavities, developmental grooves

Periodontal Prognosis& Periodontal Treatment Planning
Factors to consider when assigning overall Prognosis
1Type of periodontitis: chronic or aggressive, with or without systemic factors.
Assigning prognosis
The following factors are suggestive of fair prognosis:(one or more) - Pocket depth up to 5mm. - Up to 30 % bone loss. - Maintainable Class I furcation. - Mobility I.
Assigning prognosis:
Good Prognosis: Indicates that there is adequate periodontal support and it is possible to control etiologic factors to assure that the teeth will be relatively easily maintained.
Assigning prognosis
Poor prognosis: One or more of the following:
Moderate attachment loss. Class I and /or class II furaction(s) The location and depth of the furaction
