EndodonticsIn post core preparation, the sectional gutta-percha technique is used. This technique involves: 1) Removing the coronal portion of gutta-percha for post space preparation, 2) Leaving the apical portion intact to maintain apical seal, 3) The gutta-percha is sectioned at a predetermined level (usually leaving 4-5mm apically), 4) Heat or solvents are used to remove only the coronal portion, 5) This maintains the apical seal while allowing post placement. Thermoplasticized and vertical techniques make removal more difficult, while lateral condensation can be sectioned but is not specifically designed for post preparation.

Public Health Dentistry
The 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.

SOLUTION Gingival group of fibers
Principal fibers of the periodontal ligament rearranges themselves quite rapidly to the position in about 4 weeks.The supra-alveolar gingival fiber take as much as 40 weeks to rearrange around the new position and thus predispose to relapse.

EndodonticsThe ideal dowel length should be 2/3 the length of the root to provide adequate retention while maintaining at least 4-5mm of apical seal. This provides optimal mechanical retention without compromising the apical seal.

For caries prevention, a 0.2% sodium fluoride mouth rinse is
typically recommended for use once weekly. This regimen provides sufficient
fluoride exposure to strengthen tooth enamel without causing adverse effects.
