ABSTRACT:
Lower second premolars, closely followed by upper premolars, are regarded as the third most common teeth prone to impaction, after wisdom teeth and upper canines.
Objective of this article is to show the possibility for spontaneous eruption of impacted premolars upon extraction of deciduous molars and removal of the follicular cyst as described in several clinical cases. The present paper reports four clinical cases supporting the thesis that regardless of the reason behind impacted premolars, undertaking preventive measures significantly improves the position of the germ of those teeth.
Conclusions: The early extraction of the deciduous molar, monitoring the patient and reserving the space for the succeeding impacted premolar can lead to non-invasive or relatively short orthodontic treatment (secondary prevention).If root development is incomplete yet there is a good growth potential which could lead to spontaneous eruption (primary prevention).
Age specifics particular to children such as the great regenerative abilities of the bone, provide a good prognosis for spontaneous eruption or significant improvement in the position of impacted premolars and facilitate the orthodontic treatment.
Key words: lower premolar, second primary molar, impacted premolars, disturbed eruption, prevention,
