Public Health Dentistry - 3 Questions
Sigurd 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 cementoenamel 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).
Daily fluoride mouth rinse containing 0.05% sodium fluoride has a concentration of about 225 ppm fluoride ions 0.05% sodium fluoride solution = 225 ppm fluoride 0.2% sodium fluoride solution = 900 ppm fluoride The daily rinse (0.05%) is recommended for children aged 612 years. The weekly rinse (0.2%) is recommended for older children and adults at higher risk of caries.
DMFT (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):
Missing Teeth (M):
Filled Teeth (F):
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 ]
