It is the demand of the new era and our young dental practitioners to know various reasons of tooth extractions and changing trends in the reasons of extractions with time. The first tooth to appear into oral cavity is the first permanent molar at the age of 6-years, hence called the 6-year molar. The first permanent molar is the strongest and the largest among all the teeth. It helps in mastication and guiding eruption of other posterior teeth into proper occlusion 1 . Studies have shown that edentulous has decreased but a considerable proportion of adults are still losing teeth. Tooth loss has various harmful effects on an individual e.g. impairment of masticatory function, unpleasant aesthetics, bad phonetics, temporomandibular dysfunctions, psychological issues, social withdrawal and decrease in confidence level 2 . Common indications for extraction of teeth includes dental caries and its sequelae (e.g. pulpitis and periapical infections), periodontal diseases, tooth fracture, malpositioned or impacted teeth, Orthodontic treatment, retained deciduous teeth, prosthetic considerations, supernumerary teeth and preparation for radiotherapy 3 . It has been evident that caries and periodontitis are the most common cause of tooth loss 4 , 5 , with caries being more common than periodontitis 6 , 7 . This study was carried out with the aim that determination of various causes and pattern of tooth loss to evaluate any changing trends that will help in improving the level of oral hygiene and dental awareness among patients , thereby reducing their early extractions and consequent adverse sequelae. Therefore, the rationale of this study as to evaluate the relation of age and gender to pattern of tooth extraction among Sulaimani patients.
