Bottom Line: There was no statistical significant difference between the periotest values (PTV) taken at two different time periods with a time difference of 20 minutes.PTV of group I was found to have a statistical significant greater PTV than group II.Tooth mobility is greater during puberty as compared to adolescence and during adolescence mobility was slightly greater in males.

ABSTRACT

Unlabelled: Tooth mobility can be assessed by both subjective and objective means. The use of subjective measures may lead to bias and hence it becomes imperative to use objective means to assess tooth mobility. It has also been observed that hormonal fluctuations may have significantly influence tooth mobility.

Aims: The study was undertaken to assess the reproducibility of periotest in the assessment of tooth mobility and, to unravel the obscurity associated with the hormonal influence on tooth mobility.

Materials and methods: 100 subjects were included in the study and were divided equally into two groups based on their age, group I (11-14 years) and group II(16-22 years).

Results: There was no statistical significant difference between the periotest values (PTV) taken at two different time periods with a time difference of 20 minutes. PTV of group I was found to have a statistical significant greater PTV than group II.

Conclusion: Periotest can reliably measure tooth mobility. Tooth mobility is greater during puberty as compared to adolescence and during adolescence mobility was slightly greater in males.

Figure 2: Horizontal positioning of device away from the tooth surface

Mentions: Mobility of teeth 11, 21, 31, and 41 was measured by positioning the periotest device at the center of the tooth [Figure 1]. The periotest device is placed in a horizontal position 0.6–2 mm away from the tooth surface [Figure 2] and two PTVs (PTV1 and PTV2) were calculated with a time difference of 20 min. During each measurement, the device delivers 16 impacts in 4 s to the object. The duration of contact of the tapping head on the tooth surface is measured by the instrument that calculates the PTV, indicating tooth mobility. Mean of the two PTVs was calculated and taken into consideration for comparison. The time difference of 20 min was left between the two PTVs to allow the periodontium to return to its normal functioning state.
