The main objective of the study was to find out the common causes and pattern of permanent teeth extraction with frequency and type of replacement in patients. It was a cross sectional study conducted on 400 patients of age 16 to 65 years. Patients presenting with different dental problems were taken from two dental hospitals at Peshawar i.e. sardar begum dental hospital and Khyber college of dentistry. The study was conducted for duration of three months. Non probability convenient sampling technique was used to select the required sample. Edentulous patients, patients with congenital missing teeth, and those having systemic diseases like diabetes mellitus, cardiovascular diseases and gastrointestinal diseases were excluded from the study. Semi structured questionnaire was used to collect the data. Results of the study shows that the common causes of extraction were dental caries (63.7%), periodontal disease (22.9%), failed RCT (5.79%), impaction (2.60%), trauma (2.60%) and orthodontic reasons (2.31%). Maxillary first molar (48.5%) was the most frequently extracted tooth. The removable partial denture (69.56%) was the most commonly used prosthesis followed by fixed partial denture (26.08%) and implant supported fixed prosthesis (4.34%). Keeping in view the results of the study, Health education regarding oral hygiene is recommended to change the attitude and practices of the community in order to prevent dental problems.
