| Summary: | Aims and Objectives: Decision regarding the option to treat tooth mobility should be based on the etiology and detected severity of tooth mobility. The most widely used method of mobility assessment is to tap the tooth between two extreme positions. The study was designed to evaluate the association of Periotest values (PTV) with the amount of bone, clinical attachment loss, and various clinical indices. The aim of the present study was to evaluate the association between bone loss and Periotest values. Also we evaluated the effects of attachment loss and tooth position on the Periotest values. Materials and Methods: A total number of 60 patients between the age group of 18 and 55 years were divided into subjects with healthy periodontium (Group A), and those with Chronic Generalized Periodontitis (Group B), having a generalized pocket probing depth of 3 - 8 mm, respectively. With the help of the Periotest, Florida probe, and radiographs the assessment was carried out. The data was statistically analyzed using the Student′s unpaired t-test. Results: It was found that the values were highly significant in the incisor, premolar, and molar areas. However, the value was found to be insignificant in the canine region. The anterior teeth showed higher PTV compared to the posterior teeth; and the mandibular teeth showed higher PTV compared to the maxillary teeth. There was no association between the clinical indices and Periotest values. Conclusion: The study showed that tooth mobility was dependent on bone support as well as the clinical attachment level.
