NCT04126928

Brief Summary

PUFA Index was introduced to detect the clinical consequences of untreated dental caries. To date, there are no studies on the reliability and accuracy of the PUFA index as a screening tool. Other than indices, radiographs were sometimes used as a screening tool using the validated Periapical Index (PAI). The aim of this study was to evaluate the reliability and accuracy of PUFA and PAI in screening for clinical outcomes of untreated caries, specifically pulpal and periapical diseases. The reference standard is the clinical diagnosis, as categorized by the American Association of Endodontists. Intra- and inter-examiner reliability will be determined using Cohen's kappa. Sensitivity, specificity, positive predictive value, and negative predictive value will be calculated. Receiver Operating Characteristics (ROC) contrast estimation will be computed to compare the two index tests.

Outcome Measures

Primary Outcomes (4)

  • DMFT

    Decayed (D), missing (M), or filled (F) tooth, assessed clinically using only mouth mirror

    All variables for each person are collected at one point in time. An average visit is two hours per person.

  • PUFA

    Pulpal involvement (P), ulceration due to tooth fragments (U), fistula formation (F) and abscess (A), assessed clinically using only mouth mirror

    All variables for each person are collected at one point in time. An average visit is two hours per person.

  • Periapical Index (PAI)

    An ordinal scale of 5 scores ranging from 1 (healthy) to 5 (severe apical periodontitis), assessed radiographically. Higher scores mean a worse outcome.

    All variables for each person are collected at one point in time. An average visit is two hours per person.

  • Diagnosis of pulpal and periapical diseases

    Diagnosis of pulpal and periapical diseases using the diagnostic criteria of American Association of Endodontists following comprehensive clinical examination

    All variables for each person are collected at one point in time. An average visit is two hours per person.

Study Arms (1)

Participant

OTHER

Each participant will go through (i) screening using DMFT and PUFA, (ii) orthopantomography assessment using PAI, and (iii) comprehensive clinical examination to derive pulpal and periapical diagnoses

Diagnostic Test: Screening using DMFT and PUFA, orthopantomogram is taken and assessed using PAI, comprehensive clinical examination to diagnose pulpal and periapical conditions.
