Study Setting: Tertiary Government Hospital
Methodology: One hundred twenty six ENT-OPD patients (age 20 years old and above) participated in the study. Each prospective patient's maximum mouth opening was measured using a standard caliper and was made to rest for five minutes and then the maximum mouth opening again was re-measured using a pile of 15 tongue depressors each of which has a width of 2 mm or a total 30 mm in one pile.
Results: The patients belonging to the age bracket 30 to 39 years old have bigger average mouth openings both using the tongue depressors and a caliper. These are represented by 41.15 and 40.60 mm. In general, the range of maximum mouth opening is between 37.1235 to 45.56 mm representing the 95% confidence interval which was found to be significant as evidenced by a p value of 0.000. Its also revealed that, male patients have bigger average mouth opening compared to the female: the patients' age and BMI are good predictors of maximum mouth opening as these are associated with p-value of 0.013 and 0.05 accordingly. Moreover, there was a strong positive correlation between the average maximum mouth opening of the patients when measured using a caliper and tongue depressors. (p value =0.058)
Conclusion: These findings strongly suggest that the used of tongue depressors is as effective as the standard caliper with regards to the measurement of maximum mouth opening.
To determine the baseline range of maximum mouth opening among Filipino patients using tongue depressors and a standard caliper.
1. To determine the profile of the patient in term of the following:
1.3 body mass index (BMI)
2. To determine the average variable mouth opening of the patients using tongue depressors and a caliper in terms of:
2.3 body mass index
3. To determine whether or not there is a significant difference on the average maximum mouth opening using tongue depressors and a caliper among patients.
4. To determine the correlation between the patient's maximum mouth opening and age,gender,and body mass index
5. To construct a general 95% confidence interval on the range of the patient's maximum mouth opening among patients.
6. To determine significant predictors of maximum mouth opening.
