DISTURBANCES IN DENTAL DEVELOPMENT – FOCUS ON ETIOLOGY AND TREATMENT OPTIONS
This is an overview article on tooth disturbances starting with an introduction on tissue types important for normal tooth development and eruption. The tooth disturbances are then categorized in four groups based on aetiology according to an international classification. The groups are:
MALFORMATION – Inborn disturbance in the developmental process (syndromes diagnosed at birth are not included).
DISRUPTION – External disturbance of a normal tooth (trauma not included).
DEFORMATION – Change in form and shape caused by pressure during development.
DYSPLASIA – Inborn disturbance where cell metabolism is disturbed (amelogenesis and dentinogenesis in the whole dentition are not included). For each group clinical examples and, if possible, treatment methods, are demonstrated. Distinction is made between disturbance in one tooth, in groups of teeth (fields) and in the entire dentition. It is emphasized, that resorption during orthodontic treatment occurs in dentition with characteristic morphological disturbances. These disturbances are demonstrated.
