Abstract

ABSTRACT
Introduction: This study aimed to identify the variational types of lingula (LM)
and coronoid process of the mandible (CPM) in order to determine their
relationship and its effect on ethnicity and surgery.
Methods: A total of 100 Turkish dry mandibles were measured bilaterally to
determine the LM and CPM types. Two-way mixed ANOVA test was used to
analyze the relationship between LM and PCM types on both sides, and the
chi-square test was used for comparison of categorical variables.
Results: The occurrence of Type 4 CPM was 5.5% and type 5 LM was 1.5%.
There was a significant difference between the types of LM and CPM (X2=
48.02, p<0.05). The type 5 LM was more frequent with the type 1 CPM on both
sides (F 5, 15 = 3.254, p=0.04, p<0.05), whereas type 4 CPM was more recorded
with type3 and type5 LM. There were significant difference between the
Turkish, Brazilian and Thai populations according to the frequency of the LM
types, and between the Turkish and Indian populations according to the
frequency of the CPM types (p <0.05).
Conclusion: In conclusion, ethnicity might play a role in LM / CPM
morphology and explain why different ethnic groups have similar forms.
When type 5 LM or type 4 CPM is seen on one side of the ramus, it may indicate
that there is more than one variation in that person and give a clue about the
individual's ethnicity and effects on surgery.
