Conservative management of mandibular second premolar impaction.

The mandibular second premolar is one of the most frequently impacted teeth. The recommended treatment is to extract the second primary molar with or without removing the bone along the eruption path, to uncover the tooth surgically and move it into the arch by orthodontic treatment. This paper reports the conservative management of an impacted left mandibular second premolar which exhibited self-correction and erupted into occlusion within 18 months. The purpose of this article is to review the principles of case management of impacted mandibular premolars and to illustrate their potential to respond well to treatment.

Treatment of Space Loss Caused by Submerged Mandibular Second PrimaryMolar.

Submersion is a clinical term describing a tooth depressed below the occlusal plane. In this case report, we present treatment of a patient who had totally submerged primary maxillary second molar, which caused impaction of the second premolar and space loss in the maxillary arch due to tipping of adjacent teeth. A 19 yr old female was referred to the Department of orthodontics. Intraoral examination revealed left mandibular second primary molar was localized lingually being almost covered by gingiva and adjacent teeth inclined closing the space of the related tooth completely. Panaromic radiograph demonstrated that mandibular second premolar was impacted. Based on clinical and radiographic findings mandibular primary second molar was extracted. A pre- Adjusted Edgewise appliance (MBT prescription 022” slot) was used for creating space for the impacted second premolar. Eruption began spontaneously 6 months later.

Congenitally Missing Teeth : A Case Report.

Congenitally missing teeth have been observed as one of the most common human dental developmental anomalies. In the permanent dentition the prevalence rate of true partial exodontias is 3.5% to 6.5%. The most likely factors of hypondontia are hereditary, environmental factors and evolution. Various studies have demonstrated differences in frequency and Patten between sexes, and in frequencies among the races. A case of eight congenitally missing teeth is presented.
