    abstract = {Acute inflammation of periradicular tissues such as acute apicalabscess, acute periradicular
periodontitis, etc. is detected by reduction of the mechanical pain threshold which is defined as allodynia. It
is essential to design a standard method to assess the mechanical allodynia in patients with dental pain. Thus,
the aim of this study was to evaluate a device converting the bite force to a recordable figure based on newton
in order to measure mechanical allodynia. In this cross-sectional study which was investigated in 40
volunteered dental students, by one researcher, mechanical allodynia device was used. In the first phase, the
device was placed between the mesiopalatal cusp of maxillary first molar and mandibular first molar. This
process was followed for the contra lateral teeth. This process was performed four times with a frequency of
one minute for each side. The maximum forces were recorded and these measurements were performed againin
2 and 4 weeks again (totally 960 measurements). Data were analyzed by SPSS Software (version 21).The
maximum force in the right and left sides in different testing times were 290.97 and 278.84 N, respectively, which
is statistically significant (p<0.0001). The mean of forces for women in the right and left sides were 22.6 N and
29.3 N lower than those of the men, respectively, which was statistically significant in both sides (p<0.0001).
The mean of forces in the three periods obtained through the analysis of linear effect of age showed
that 0.33 and 2 N less forces were exerted for each year increase in age in the right and left sides, respectively.
This change, however was statistically significant in the left side (p<0.04). The interclass correlation coefficient
(rho) in the right side was 0.6 (p<0.0001) and in the left side was 0.56 (p<0.0001). This device has the potential
to be used for the repeatable measurement of bite force in every individual at different periods.}
