SUMMARYHuman facia! pattern has undergone such great variety through marriege of persons from different ethnic groups and different facial pattern that, to determine a standard applicaple to every body seems almost impossible. At the present time some authorities don't belive in putting a norm for facial pattern. Wilson says, «There is nc such thing as normal, but a mean value and values approoching to, and departing from it in resannable limit may exist. If so what has to be done in our clinical activities Surely we must be gokled, especially beginners need a guide in clinical performances. Following these consideratians we have to try to determine a norm, a standard to facilitate our clinical activities and perform them in a way to get satisfactory results.Many authorities who have realised this fact h/ave put forth some standart in the form of drawings and indices to show normal dental arch form and the relations of facial parts such as lips and chin to a point in the face or on the head-In this paper it is intended to show first, the principles of throe photographical methods showing normal facial pattern and second to introduce a new photographical diagnostic method. The principles of the three methods are as follows :1. P. Simon of Berlin is the first auther to show by photography the normal antero - posterior position of lips and chin using orbital plane which passes through orbital and gnathion points being perpendicular to F. 'H. Izard used glabellar plane which passes through glabella point being perpendicular to F. <H. This plane is almost tangent to upper lip and leaves the lover one a little bit behind. The chin point occupies a position midway between these two planes.2. V. Andersen, points out that F. H. and orbital planes are mostly used in antropologic measurements, and for gnathologic workto use Comper's auriculo-nasal plane which is also used in radiology and prothetics, would be more suitable and practical. This author Draws a line tangent to the back of nostril, which is perpendicular to Comper's plane, and is called the cental line, Together with central line and Walckervs' nasion gnathion axishe succeded to establish a pho-tographical method to diagnose facial abnormaities. Andersen calls his method the (Gnathopysiognomic method).3. Another photographical method belongs to Prof. Mujy, who asserts that glabellar plane is only 30 % applicaple, and one can not always get form its use a satisfactory result. He also claims that the frontal point in the middle of the upper most of the forehead has to be taken into consideration in dealing with the cephalometric measument of profile, and uses fronto = facial angle as the basis of his method.
