Clinical Measurement of Maximum Mouth Opening in Children of Kolkata and Its Relation with Different Facial Types
Introduction: Maximal opening of mouth is described as the greatest distance between incisal edge of maxillary central incisor to the incisal edge of mandibular central incisor, when the mouth is opened as wide as possible painlessly or as the inter incisal distance plus the overbite. Clinical m...

| Summary: | Introduction: Maximal opening of mouth is described as the
greatest distance between incisal edge of maxillary central
incisor to the incisal edge of mandibular central incisor, when
the mouth is opened as wide as possible painlessly or as the
inter incisal distance plus the overbite. Clinical measurement of
normal range of Maximum Mouth Opening (MMO) in children is
an important diagnostic criterion for evaluation of stomatognathic
system, especially for those with temporomandibular and
neurogenic dysfunctions.
Aim: To determine the correlation of maximal mouth opening
with age, sex, height, body weight and different facial types.
Materials and Methods: The study was a cross-sectional study
which was conducted on 434 children, who were randomly
divided into three groups based on their age: Group I- children
of age 6 to 8 years, Group II- children of age 8.1 to 10 years,
Group III- children of age 10.1 to 12 years. For each child,
the examiner took three readings of MMO in millimeters (mm)
and the mean of the three readings was considered. Age, sex,
standing height, body weight and facial type of each child were
also recorded simultaneously. Pearson correlation was used to
determine the relationship between the different parameters.
p-value <0.05 was the bench mark for statistical significance in
the analysis. Descriptive and inferential analysis was done for
the data using SPSS version 20.0. (SPSS 20, inc.; Chicago).
Results: The estimated average MMO measured for girls and
boys in the age range of 6-8 years, with a total sample size of
139, was 41.14 ± 4.29 mm and 42.16 ± 3.98mm respectively in
euryprosopic face type. In leptoproscopic face type, it was 42.12
± 4.54mm and 43.76 ± 3.80 mm in girls and boys respectively.
In mesoproscopic face type, MMO measured was 41.77 ±
4.09mm and 42.51 ± 3.95 mm in girls and boys respectively.
The estimated average MMO measured for girls and boys in the
age range of 8.1-10 years, with a total sample size of 143, was
44.42+4.69mm and 43.30 ± 4.11 mm in euryprosopic face type.
In leptoproscopic face type, it was 43.02 ± 3.92mm and 46.29
±3.09mm in girls and boys respectively. In mesoproscopic face
type, MMO measured was 42.50 ±4.32 and 42.80 ± 5.16 mm in
girls and boys respectively.
The estimated average MMO measured for girls and boys in
the age range of 10.1-12 years, with a total sample size of 152,
was 44.63 ± 5.28 mm and 45.80 ± 5.18 mm respectively in
euryprosopic face type. In leptoproscopic face type, it was 45.76
± 4.98 mm and 46.28 ± 4.68 mm in girls and boys respectively.
In mesoproscopic face type, MMO measured was 45.32 ± 5.80
mm and 46.03 ± 5.86 mm in girls and boys respectively.
Conclusion: There was a significant difference in MMO
between males and females; with males having higher values
in all age groups. MMO is seen to increase with age in a
statistically significant manner. Significantly increased value of
MMO was observed in leptoproscopic face type in comparison
to euryproscopic and mesoproscopic face type for each age
group. |
