Determination of the vertical dimension is based on patient's resting jaw position, which is the physiological vertical dimension. Objective: To examine the accuracy of physiological vertical dimension using digital photography. Methods: The research was done on 64 students who meet the criterias. The measurements of eyes-lips angles and lower nose-chin distance was performed. Then photo shoot of subject faces was taken from 56cm distance between the camera lens and the tip of the subjects' nose with tripoded camera. Results: Distance of eyes-lips angles, and lower the nose-chin of the face and the photo has no meaningful differences. Conclusions: Analysis of digital photos can be applied to predict physiological vertical dimension.
ABSTRAKAnalisis foto digital untuk memprediksi dimensi vertikal fisiologis. Penetapan dimensi vertical (DV) diperoleh berdasarkan DV pada saat posisi istirahat rahang pasien yaitu dimensi vertikal fisiologis (DVF). Tujuan: Meneliti keakuratan pengukuran DVF dengan menggunakan foto digital. Metode: Penelitian dilakukan pada 64 mahasiswa yang memenuhi kriteria. Kemudian dilakukan pengukuran jarak sudut mata-sudut bibir dan jarak dasar hidung-ujung dagu pada wajah subjek. Lalu dilakukan pemotretan wajah subjek penelitian dengan ketentuan jarak 56cm antara lensa kamera dengan ujung hidung subjek dengan kamera di atas tripod. Hasil: Jarak sudut mata-komisura bibir kanan dan kiri wajah, dan jarak dasar hidung-ujung dagu pada wajah dan foto tidak memiliki perbedaan bermakna. Simpulan: Analisis foto digital dapat diterapkan untuk memprediksi DVF.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
