This is different from the findings of Ciner (1960), which showed that the leptoprosopic type was dominant in Turkish females.
This classification of facial types is as follows; mesoprosopic type (84.0-87.9), euryprosopic type (79.0-83.9), hypereuryprosopic type (<78.9), leptoprosopic type (88.0-92.9), hyperleptoprosopic type (>93.0) (Mane et al.).
In the Garson classification of facial index there are five types: hypereuryprosopic ([less than or equal to]78.9), euryprosopic (79.0 to 83.9), mesoprosopic (84.0 to 87.9), leptoprosopic (88.0 to 92.9), and hyperleptoprosopic ([greater than or equal to]93.0) (Inaba et al.).
Yoruba males and females have the leptoprosopic face type based on classifications of face types from facial indices.
The face is classified based on the FI or prosopic index as hypereuroprosopic or very short broad face (FI < 79.9), europrosopic or short broad face (FI of 80–84.9), mesoprosopic or medium round face (FI of 85–89.9), leptoprosopic or long narrow face (FI of 90–94.9), and hyperleptoprosopic or very long narrow face (FI > 95).[sup], The facial indices in Yorubas (91.8 in males and 91.4 in females) [Table 2] examined in the present study implied that Yoruba males and females have the leptoprosopic face type.
The second commonest type of facial shape for females was europrosopic (broad face) which was 24% but for males it was leptoprosopic (long face) which was 20%.
(2013) carried out a study in Central Serbia and showed a similar result of sexual dimorphism which was significant as in the present study, but the dominant face type was leptoprosopic followed by mesoprosopic which was not similar to our study .
According to Kieffer, individuals with short and broad faces (Chamaeprosopic) has smaller angle than individuals with a long and narrow face (Leptoprosopic
1) revealed a leptoprosopic
facial form, convex profile and a gross facial asymmetry on the left side of the face.
In this regard leptoprosopic
(long face) individuals usually have tapered arch forms while euryprosopic (short face) individuals tend to have a broader square arch form.11 The most used arch form in the MBT philosophy is the ovoid arch form especially during the initial phase of treatment and the main purpose of this is to reduce the inventory.12 The general concept of arch form development is that initially it follows the shape of the underlying bone but later when the teeth are fully erupted it is shaped by the forces of the surround- ing musculature.13
These traits are different in the mestizo group of Cali, as their microevolutive process and population dynamics is rather different, giving a facial biotype longer and shorter (leptoprosopic
However, though Evenks , Mongol , and Manchu  tribes belong to Mongoloid race, they show hyperleptoprosopic or very narrow face to leptoprosopic
