To evaluate the differences between tooth material and arch dimensions, Arch perimeter model analysis is carried out prior to starting orthodontic treatment. GROUP I. A: 25 male subjects following this criterion GROUP I. B: 25 female subjects following this criterion In the Group II (crowded group), maxillary and mandibular casts of 50 subjects (25 boys and 25 girls) were selected on the basis of gross crowding, who were in the age group of 13 to 21 years with crowding more than 2 mm. This group also was further subdivided into two groups for sex predilection. B: 25 female subjects with crowding The measurements were taken on dental casts of these groups were:- * Lingual arch width for first molar was measured at the cervical region from midpoint of the lingual surface of the molar to corresponding point on its antimere. * Lingual arch width for canine was measured at the cervical region from midpoint of the lingual surface of the canine to corresponding point on its antimere. * Buccal arch width for first molar was taken from a point, 5 mm apical to the mesiodistal centre of the molar towards gingival margin, to its corresponding point across the dental arch. * Buccal arch width for canine was measured from a point, 5 mm apical to the mesiodistal centre of the canine towards gingival margin, to its corresponding point across the dental arch. * Arch perimeter was measured from distal surface of 1st permanent molar to the distal surface of opposing molar at the buccal aspect according to Proffit method. After the measurements were made and tabulated, the following comparisons were done: a. Between canine arch width (lingual and buccal) b. Between molar arch width (lingual and buccal) c. Between arch perimeters Statistical Analysis: all the data is entered in MS Excel and analyzed through SPSS Software 10.0 (Trail version) and unpaired T test is used in data analysis Result: Two sets of readings were taken for all parameters to determine any significant intra-observer difference.
