Background: Hypodontia is one of the frequently observed dental anomalies in which dentofacial esthetics, phonetics, mastication, self-esteem and quality life can be adversely affected. Awareness disproportionate tooth number important must considered by orthodontists while making treatment plans to achieve proper occlusion, overbite, overjet, order restrain oral health deterioration. The aim this study was determine frequency non-syndromic hypodontia orthodontic patients its association with skeletal malocclusion. Methods: This retrospective case-series conducted at department Orthodontics, Sharif Medical & Dental College. It involved screening records from last 5 years October 2017 – 2021, consisting standardized good orthopantomograms lateral cephalograms. Patient files incomplete records, any craniofacial syndrome and/or previous history loss were excluded. Non-syndromic malocclusion recorded along demographic data, predesigned proforma. Results: Out 244 patients, 18 (7.37%) had hypodontia. Moreover, 63 teeth missing NSH. Maxillary arch (52.4%) upper left quadrant (28.6%) found more difference among arches, quadrants statistically significant for genders it insignificant. Conclusion: significantly associated malocclusion, highlighting their genetic etiology. Most commonly absent maxillary incisor followed mandibular second premolar incisor.
