Abstract

A study was conducted to investigate the pattern and causes of tooth loss among Eastern Libyans. A total of 7606 dental extractions were carried out on 6550 patients. The investigations revealed two major causes of tooth loss i.e. dental caries (56.42%) and periodontal disease (31.86%). Other important causes were trauma (3.68%), Impaction (3.54%), Prosthodontic causes (2.55%) and Orthodontic causes (1.31%). Dental caries was the main cause of tooth loss during the 2nd, 3rd and 4th decades, while periodontal disease was the prevalent etiologic factor during the 5th, 6th and 7th decades of life. Posterior teeth were the most extracted due to dental caries (47.69%) while anterior teeth showed the highest rate of extraction due to periodontal disease (34.65%).
