Prevalence of Congenitally Missing Premolars in College of Dentistry, King Khalid University, Abha, Kingdom of Saudi Arabia: Can Early Treatment Make A Difference?
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2018, Vol 6, Issue 3
Abstract
Introduction: Congenitally missing teeth are those teeth whose tooth germ did not develop adequately to allow the disparity of the dental tissues. Inherited absence of mandibular second premolars has an impact on orthodontic patients. The orthodontist should make the proper treatment plan regarding management of the edentulous space. The purpose of this study was to determine the prevalence of congenitally missing premolar in children aged 6–14 years who attended the College of Dentistry, King Khalid University, Abha KSA using OPGS. Materials and Methods: In this retrospective study, a total of 1100 panoramic radiographs (OPG’S) of children who attended dental clinics at College of Dentistry, King Khalid University, Abha, were viewed for congenitally missing premolar with age group of 6–14 years. Digital orthopantomogram was examined in a standard manner under good lighting conditions. Data were collected and embarked into spreadsheet (Excel 2013: Microsoft office) and analyzed. Results: A total of 1100 OPG’S were viewed for congenitally missing premolar with age group of 6–14 years. The prevalence for congenitally missing premolar was seen more in girls (59.4%) than boys (40.6%). The frequency of most congenitally missing premolar was mandibular 2nd premolar followed by maxillary 2nd premolar in both girls and boys. Conclusion: Congenitally missing premolars were seen more in girls than boys, and mandibular 2nd premolar was most common missing tooth followed by maxillary 2nd premolar. Some early decisions that the orthodontist makes for a patient whose inherited mandibular second premolars are missing can influence the dental health for a lifetime. Therefore, the accurate decision must be made at the appropriate time.
