Abstract :

?e debate and controversy of extraction and non extraction has nearly been 100 years old. Some researchers claim extraction to constrict arch and subsequently create unaesthetic black triangles at the corner of the mouth, however recent studies show that instead extraction treatment causes increase of arch width..Anterior and posterior arch widths of the maxillary and mandibular arches of 35 patients treated by 4 first–premolar extraction and 35patients treated without extractions were measured on pretreatment & posttreatment study models and compared statistically to determine whether the dental arches were narrower after extraction treatment, to test the accuracy of this view. Measurements were made in the canine and the molar regions from the most labial aspect of the buccal surfaces of the canines and the molars. ?ere is significant increase in intercanine arch widths were the same except for in Extraction patients, and insignificant increase in nonextraction patients
