Trial 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). Read more about this study

About this study

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.

Read the detailed description

The index of decayed-missing-filled permanent teeth (DMFT) records decayed (D), missing (M), or filled (F) teeth in an individual, but it fails to give information about the clinical outcomes of untreated dental caries. A new index complements the DMFT index by recording the advancement of the caries lesion into surrounding tissues, including pulpal involvement (P), ulceration due to tooth fragments (U), fistula formation (F) and abscess (A). The PUFA index has yet to be validated in the adult population. Other than indices, radiographs were sometimes used as a screening tool using the validated Periapical Index (PAI). Hence, the aim of this study is to evaluate the reliability and accuracy of PUFA and PAI in screening for clinical outcomes of untreated caries, specifically pulpal and periapical diseases. The study will be carried out in Primary Care Clinic, Faculty of Dentistry, Universiti Kebangsaan Malaysia. Consecutive sampling will be used; all eligible patients are invited to participate. The inclusion criteria are as follow:

  1. New patient, not receiving active dental treatment at the time of study ii. Adult patient (18 years old or above) iii. Having at least 12 teeth in the oral cavity iv. Presented with the clinical situation for which radiograph(s) were indicated v. No radiograph was taken within the last six months The reference standard is the clinical diagnosis, as categorized by the American Association of Endodontists. A comprehensive examination will be carried out for each tooth, followed by investigation using orthopantomography (OPG), periapical radiograph, periodontal probing, heat test, cold test, electric pulp tester when indicated, to aid in arriving at the definitive diagnosis.

Two independent, trained dentists are employed to screen the participants using DMFT and PUFA indices, blinded to the clinical diagnosis and PAI scoring. The examination is done using only a mouth mirror.

Another two independent, trained dentists, blinded to the clinical diagnoses and the PUFA scoring, will score each tooth on the orthopantomograph for the periapical status using the Periapical Index (PAI).

The outcome of PUFA is dichotomized as Positive (PUFA>0) or Negative (PUFA=0) for each tooth. Similarly, the PAI was dichotomized as Positive (PAI≥3) or Negative (PAI<3). Intra- and inter-examiner reliability will be determined using Cohen's kappa. Sensitivity, specificity, positive predictive value, and negative predictive value will be calculated. ROC contrast estimation will be computed to compare the two index tests.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. DMFT

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

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

  2. PUFA

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

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

  3. 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.

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

  4. 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

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