A total of 42 representative goat fetuses from 10th week of gestation to full term (CR length 12.0 cm to 41.2 cm) were utilized for the present investigation. Incisor blocks and hemisections of head were radiographed in dorso- ventral and latero-medial projection, respectively. The sequential progression of development of deciduous incisors was found as Di1, Di2, Di3, Di4. The beginning of crown formation was detected at 12th, 13th, 14th, 15th week for Di1, Di2, Di3 and Di4 in goat fetuses, respectively. The complete crown formation and beginning of root formation was detected at 18th, 19th, 20th, 21st week for Di1, Di2, Di3 and Di4, respectively. At full term, roots of all deciduous incisor teeth were at various levels of development but none had completely formed. The present investigation revealed bilateral symmetry in deciduous incisor teeth development in goat fetuses. There was no any radiographic indication for development of upper deciduous incisors as well as permanent incisor teeth in upper and lower jaw. The scientific baseline data generated from the present study on various radiographic developmental stages of deciduous incisor teeth could be utilized as guideline to estimate age in goat fetuses from 12 weeks to full term.
