DBA


2/22

Another Index for measuring PeriodontalDisease designed by Henry C. Sandlerand Sigmund Stahl

The average percent of the teeth perperson showing positive sign ofperiodontal disease

In order for the tooth to be classified ashaving periodontal disease, it must meetone or more of the following minimumcriteria:


3/22

Gingivitis


4/22

Gingival Hyperplasia


5/22

Gingival Necrosis


6/22

Deepening of the gingival sulcus of 3 mmor more


7/22

Displacement of the tooth more than 1 mmin any direction.


8/22

Radiographic evidence of bone loss over 3

mm from the cemento-enamel junction


9/22

If the diagnosis is doubtful, it should beclassified as negative.

Each individual tooth present in the

mouth is rated as to the existence orabsence of periodontal disease.

There is no differentiation as to the

character of the lesion, its chronicity, thedegree of bone loss, or the prognosis.


10/22

It is reasonably practical for the

study of large populations.


11/22

Determine the status of periodontiumbased on the criteria given

Identify the number of teeth affected withperiodontal disease

Divide by the total number of teeth of thesubject


12/22

Number of teeth affected

by periodontal disease

Total tooth populationof an individual

Huda , Amel and Afnan, 30, 45and 40 years old respectively

received a periodontalassessment made by Dr. Fouadto examine their periodontal

status. The results are thefollowing:

17/22

Periodontal disease rate was developedby Henry C. Sandler and Sigmund Stahl in1960 in their study to measure the

prevalence of periodontal disease in ahospitalized population.

The sample studied was drawn frompatients who were hospitalized at theVeterans Administration Hospital,Brooklyn, New York.


18/22

The purpose of the study was todetermine whether persons with confirmeddiagnoses of specific diseasesdemonstrate a greater prevalence ofperiodontal disease than those who are inrelatively good health


19/22

Results of the Study:

The influence of generalized diseasesupon periodontal health was notremarkable

Periodontal disease was also higher, butnot significantly, in patients witharteriosclerosis and GI disorders


20/22

The number of tooth present in the subjectaffects the increase or decrease of theperiodontal disease rate
