“…On analysis of results, the mean MIO in the present study showed a gradual increase with age with a mean MIO of 41.34 mm at 4–5 years to a mean MIO of 51.73 mm at 14–15 years. This is in agreement with the findings of previous studies [381421] conducted in pediatric population. Ying et al .…”

Background: Restricted mouth opening is a common complaint in patients suffering from temporomandibular joint disorders, ankylosis, impaired masticatory muscle function, rheumatic disease, infection, or malignancy. As with any disease, the aim of treatment of disorders affecting mouth opening is to restore the mouth opening to its normal value. It is thus of paramount importance to determine the normal value. Objective: To establish the normal range of maximal incisal opening (MIO) in children aged 4 to 15 years and to investigate the correlation between MIO and age, gender, height, and body weight. Materials and Methods: Six hundred and two children from various schools in Bengaluru, India, participated in the study. The children were divided into the following age groups: 4–5, 6–7, 8–9, 10–11, 12–13, and 14–15 years. MIO for the children was recorded using Therabite ® scale. The measurements of MIO were then correlated with gender, body weight, and height of the children in different age groups. Results: It was observed that MIO gradually increased with age with a mean MIO of 41.34 mm at 4–5 years to a mean MIO of 51.73 mm at 14–15 years. The mean MIO value for males (48.90 ± 6.49 mm) was found to be higher when compared to that of females (46.17 ± 5.58 mm). The results indicated a strong positive correlation of MIO with height and weight. Conclusion: MIO gradually increased with age in both the genders, and a strong positive correlation of MIO with height and weight was observed.

“…Hence, it becomes essential to establish the parameters to be taken into consideration for evaluating normal mouth opening for the population. Moreover, only a few studies [3891011121314] have been conducted to determine the maximal mouth opening in children.…”

“…Literature reports indicate that the range of mouth opening changes with age of the body. Additionally, in the initial period of life it grows [ 30 ] until achieving maturity. At the time of achieving maturity the possibility of broad mouth opening is becoming gradually limited [ 31 ].…”

The Purpose of the Paper. Qualitative and quantitative analysis of selected parameters of mandible movements, electronically registered in patients with temporomandibular joint dysfunction and healthy ones. Material. Function test of the mandible movements was conducted in 175 patients. Gender distribution was 143 women and 32 men, aged 9 to 84. Methods. The studied population, after accurate clinical examination, was divided into age groups with the range of five years. All the patients had Zebris JMA computerized facebow examination done, according to the generally accepted principles and procedures. Results. Mean values of mouth opening calculated to 45.6 mm in healthy group and 37.6 mm in TMJ dysfunction group. Mean length of condylar path amounted to 39 ± 7% of the maximum value of mouth opening in the group of healthy people, 44 ± 11% in the case of muscle-based disorders, and 35 ± 11% with joint-based. The mean value of the condylar path inclination oscillated in the range of 25° to 45°. Conclusions. The ratio of length of the condylar path to the size of mouth opening may be a significant value characterising the type and degree of intensification of the TMJ dysfunctions.

“…Assessing mandibular movement is considered an important clinical tool for evaluating the state of TMJs and their associated structures, where a decrease or increase in the values of these ranges can be associated with an alteration (Bonjardim et al, 2004;Sousa et al, 2008;Abou-Atme et al, 2008;Kumar et al, 2012). Numerous studies use the range of mandibular opening for such purposes.…”

Odontostomat., 11(1):83-87, 2017. ABSTRACT:Assessing the normal range of manibular movement becomes an indispensable tool for the clinical evaluation of the function of the masticatory system. The aim of this study was to measure the range of mandibular movement in mouth opening, protrusion, and lateral movements in pediatric subjects from the city of Temuco, Chile and to determine their association with age, sex, and height. A cross-sectional study was performed in children aged 6-13, treated in the Teaching-Unit-Dental-Clinic at the Universidad de La Frontera, Temuco-Chile. 54 subjects participated in the study (44.4 % females); girls exhibited an average mouth opening of 51.9 mm and males of 54.8 mm. Averages were 53.5 mm for mouth opening, 11.8 mm for protrusion, 9.9 mm for right laterality, and 10.3 mm for left laterality. A statistically significant difference was found between age groups, opening, and right lateral ranges, as well as a weak to moderate correlation between mouth opening and protrusion, protrusion and right laterality, protrusion and left laterality, right and left laterality, height and mouth opening, and height and right lateral ranges. The results of this study provide specific data and evidence on the importance of evaluating all ranges of mandibular movement, relating them to each other and with variables such as age and height.
