Abstract
I. Introduction
It is a challenge for endodontists to make a diagnosis and treat teeth with abnormal root morphology. Germination is the one of abnormal tooth morphology which is defined as a single enlarged or joined tooth where the number of teeth present is normal. Geminated teeth demonstrate two crowns or one large partially separated crown sharing a single root or root canal. According to many studies, germination could be found commonly in the permanent maxillary incisors and the deciduous mandibular incisors. The prevalence of germination was reported from 0.1% to 1%. This case report presents a geminated mandibular premolar with two canals.
II. Case Presentation
1. Sex/age : M/12
2. Chief Complaint : Referral from Pediatric dentistry due to periapical abscess on #44
3. Past Dental History : Pulp extirpation was done due to abscess on #44 at local dental clinic
4. Present Illness : #44
5. Gemination, Temporary sealing state, Per(+), Mob(-), Periapical lesion(+), Open apex
6. Impression : Pulpless state with chronic apical periodontitis on #44
7. Tx Plan : #44 Re-Endodontic treatment
III. Conclusion
In this case, geminated immature premolar was successfully treated. Two roots were separated each other by thin dentin layer. Apexification with the MTA was done at the root canal with necrotic pulp. And another root canal with vital pulp remained untreated and undergone normal developmental process. The endodontist must be able to diagnose, differentiate and treat dental anomalies adequately, with the goal of maintaining patients¡¯ oral health.
