Hypodontia Causes - Can be environmental or genetic - May be isolated or associated with syndromes such as ectodermal dysplasia and Down syndrome

Diagnostic Method - Dental panoramic tomograph screening is used - Screening should be done no earlier than 9 years of age

Prevention - No specific prevention methods identified

Treatment - Focus on preventing tooth loss due to caries, periodontal disease, and trauma - Requires a multidisciplinary approach involving paediatric, orthodontic, and restorative specialties - Management varies depending on the stage of dental development

Hypodontia Overview - Developmental absence of one or more teeth, excluding third molars - Common dental anomaly with negative impact on function and appearance - Rarely occurs in primary teeth, with adult second premolars and upper lateral incisors most commonly affected - Often part of a syndrome requiring multidisciplinary treatment - Can be classified as hypodontia, oligodontia, or anodontia based on the number of missing teeth

Signs and Symptoms - All baby teeth should be present by age three - Adult teeth typically erupt between ages 6 and 14, except for wisdom teeth (third molars) which erupt between ages 17 and 25 - Panoramic x-rays are taken if a tooth has not erupted by the appropriate age

Dental Features - Microdontia, where teeth appear smaller than normal, may be present in one or more teeth - Microdontia can be genetically linked and may be associated with ectodermal dysplasia, cleft lip or palate, or Down syndrome - Delay in tooth development can indicate hypodontia, as the absence of an adult successor slows down the normal resorption of baby teeth roots
