The textbook "Occlusal Features, Perception of Occlusion and Orthodontic Treatment" offers a comprehensive analysis of malocclusion, defined as a deviation in the arrangement of teeth. It addresses various anomalies within the dental arches, including overcrowding and positioning, as well as the relationship between the dental arches and their impact on jaw structure. The authors, Fakhri Abid Ali Al-Fatlawi and Zaynab Mohamed Ridha, investigate the prevalence of malocclusion in different populations and age groups, highlighting the importance of epidemiological studies for a better understanding of issues related to malocclusion. By comparing with previous studies from Iraq, a deeper understanding of the perception of occlusion and the need for orthodontic treatment is established. This book is aimed at professionals in the fields of medicine and nursing who deal with dental and orthodontic topics.
