Public Health DentistrySigurd Ramfjord introduced the Periodontal Disease Index
a clinical tool that used a periodontal probe , with marks at 3, 6 and 8 mm, to measure the distance from the cemento–enamel junction to the bottom of the pocket (i.e. attachment loss)
Ramfjord recommended the assessment of six ‘index teeth’ that soon became known as the ‘Ramfjord teeth’ These teeth were: maxillary right first molar (tooth 16), maxillary left central incisor (tooth 11), maxillary left first bicuspid (tooth 24), mandibular left first molar (tooth 36), mandibular right central incisor (tooth 41) and mandibular right first bicuspid (tooth 44).

Public Health DentistryA measure that has validity is necessarily reliable, as reliability
is a prerequisite for validity. However, a measure that is reliable does not
necessarily mean it is valid. Validity refers to the degree to which a
measurement tool accurately measures what it is intended to measure. Reliability
is the consistency of the results produced by the tool.

Public Health Dentistry1. Rate: A rate is a measure that expresses the change in one variable with
respect to another variable, often over a specific period of time. It is
typically used to express quantities like speed, velocity, heart rate, or the
occurrence of an event within a given time frame. For instance, the rate of a
car traveling might be measured in miles per hour (miles/hour) or the rate of a
reaction in chemistry might be measured in moles per second (mol/s).
2. Distribution: In the context of data analysis, a distribution is a pattern of
the range and frequency of values in a dataset. It can be represented visually
using histograms, box plots, or probability density functions. Distributions
help in understanding the spread and concentration of data and can be
categorized into types such as uniform, normal (bell-shaped), skewed, or
bimodal, among others.
3. Data: This is the raw information or material that is processed to extract
knowledge or insights. Data can be qualitative or quantitative, structured or
unstructured, and is used in various fields for decision-making, analysis, and
research. It can take the form of numbers, text, images, sound, or video, and is
often collected through surveys, experiments, or observations.
4. Frequency: As defined earlier, frequency is the number of occurrences of a
particular value or range of values in a dataset. It is fundamental in creating
frequency distributions and is used in various statistical measures such as
mode, median, and mean to describe the data's characteristics.

Public Health DentistryStannous fluoride is often favored for adults due to its ability to provide antimicrobial benefits along with its fluoride release, which can help in controlling dental caries and reducing sensitivity. It is commonly found in toothpaste and mouth rinses and is known for its effectiveness in preventing cavities and plaque formation.

Public Health DentistryGroup discussion
because participants get chances to express thier views Idea
panel discussion : 4-8 people talk abt a topic in front of large group.
symposium:series of speeches on a selected subject, no discussion.
group
discussion :considered a very effective method of health edu if the
group consists of not less than 6 and not more than 20
persons.
workshop:usually lasts for few days wher people get together and work in
different groups and discuss problem of concern
it can be
called a problem solving method.

Public Health DentistryThe Snyder test is a microbiological test used to detect the presence of
specific bacteria associated with dental caries, primarily Streptococcus mutans.
It involves taking a sample of plaque, adding a sugar solution, and observing
for the formation of acid that indicates bacterial activity and the potential
for tooth decay. It is not used to detect fungal growth on skin or determine the
pH of crevicular fluid.

Public Health DentistryDMFT (Decayed, Missing, Filled Teeth) score takes into account both deciduous
(primary) and permanent teeth.
To calculate the DMFT score for the child based on the information provided:
Decayed Teeth (D):
6 active carious lesions in deciduous teeth.
No mention of decayed permanent teeth, so D = 0 for permanent teeth.
Total D = 6 (from deciduous teeth).
Missing Teeth (M):
1 missing deciduous tooth.
4 missing permanent third molars (not counted in DMFT since they are
not included in the DMFT calculation until the child is older).
Total M = 1 (from deciduous teeth).
Filled Teeth (F):
1 filled permanent tooth.
No filled deciduous teeth mentioned, so F = 0 for deciduous teeth.
Total F = 1 (from permanent teeth).
Now, we can calculate the DMFT score:
[ DMFT = D + M + F ]
Substituting the values:
[ DMFT = (6 + 0) + (1 + 0) + 1 = 6 + 1 + 1 = 8 ]
So, the DMFT score for this child is 8.
If the question is asking for the df score (which only considers deciduous
teeth), it would be:
[df = 6 + 0 + 1 = 7 ]
In summary:
DMFT score (including both deciduous and permanent teeth) = 8.
df score (only deciduous teeth) = 7.

Public Health DentistryThe DMFT (Decayed, Missing, Filled Teeth) index is used to assess the dental
health of a population by counting the number of decayed (D), missing (M), and
filled (F) permanent teeth (T) in an individual. It provides a cumulative
measure of dental caries experience, as it includes both untreated and treated
cases of dental decay. This index helps in understanding the overall oral health
status and the need for dental care in a population.
