Abstract :
        Background and aims: Ever since the emergence of new orthodontics, numerous indices  have  been  developed  to  predict  normal  maxillary  arch  widths.  Accurate prediction is essential for resolving dental crowding, ensuring stable occlusion, and minimizing  the  likelihood  of  relapse.  The  aim  of  this  study  was  to  assess  the validity of Pont’s Analysis in a group drawn from the Yemeni population residing in Sana’a.Methods:  This  cross-sectional  study  examined  dental  casts  obtained  from  100 Yemeni  participants  (62  males  and  38  females)  aged  18–25  years  with  normal occlusion.  Measurements  were  conducted  with  a  high-precision  sliding  caliper (accuracy:  0.01  mm).  In  addition  to  themesiodistal  lengths  of  the  four  upper incisors,  arch  widths  were  measured  at  the  first  premolar  region  (between  distal pits)  and  the  first  molar  region  (between  mesial  pits).  The  statistical  package  for social science software was used to conduct the statistical analysis.Results:  The  analysis  revealed  a  statistically  significant  disparity  between  the measured and calculated arch widths. Pont’s Index consistently overestimated arch widths  in  both  males  and  females  (p
