Treatment of Teeth with Apical Root Resorption Using MTA

Abstract

ABSTRACT Objective: Apical stenosis may be impaired due to pulpal pathologies, iatrogenically, etc. Apical inflammatory root resorption usually occurs due to periapical pathology without any clinical symptoms. The aim of this case series is to utilize calcium silicate based materials to provide hermetic occlusion in the treatment of teeth with compromised apical integrity. Case Report: Case 1: A 21-year-old woman with no systemic disease. Tooth number 11 had swelling and fistula tract extending to the buccal mucosa. Clinical examination revealed inadequate and incomplete root canal treatment and extensive lesion in the apical region. The old root canal treatment was removed. Apical narrowing was found to be impaired. After dressing with Ca(OH)2, MTA (mineral trioxide aggregate) was placed in the apical region. Root canal treatment was completed with the warm vertical condensation technique in the middle and coronal region of the root. Six months later, the patient was called for a follow-up visit and it was observed that all objective complaints had resolved and the periapical lesion had disappeared in the radiographs. Case 2: A 43-year-old male patient with no systemic disease. Radiographic images obtained from the patient revealed dentigerous cysts affecting teeth number 38 and 37. External root resorption was detected in the distal canal of tooth number 37. The entire distal canal of tooth number 37 was filled with MTA and the mesial canals were filled with gutta percha. Tooth number 38 was extracted and the dentigerous cyst was enucleated. The patient was called for follow-up three and six months later and it was determined that all objective complaints had resolved and the borders of the periapical lesions had healed in the radiographs. Conclusion: In cases of external root resorption with impaired apical stenosis, conservative endodontic treatment with effective irrigation, Ca(OH)2 medicaid and MTA in combination with an apical plug is one of the successful treatment options.

Apikal Kök Rezorpsiyonu Olan Dişlerin MTA ile Tedavisi

Abstract

ÖZET Amaç: Pulpal patolojilere bağlı olarak, iatrojenik olarak vb. etkenler ile apikal daralım bozulabilmektedir. Apikal enflamatuar kök rezorpsiyonu genellikle herhangi bir klinik belirti göstermeden, periapikal patolojiye bağlı olarak meydana gelmektedir. Bu vaka serisinin amacı apikal bütünlüğü bozulmuş dişlerin tedavilerinde kalsiyum silikat esaslı materyallerden yararlanılarak hermetik tıkama sağlamaktır. Vaka Raporu: Vaka 1: 21 yaşında kadın hasta, sistemik hastalığı bulunmamaktadır. 11 numaralı dişinde bukkal mukozaya yayılmış şişlik ve fistül yolu mevcuttu. Klinik muayenede yetersiz ve eksik kök kanal tedavisi ve apikal bölgede yaygın lezyon tespit edildi. Eski kök kanal tedavisi söküldü. Apikal daralımın bozulmuş olduğu tespit edildi. Ca(OH)2 ile yapılan pansuman sonrası apikal bölgeye MTA (mineral trioksit agregat) yerleştirildi. Kökün orta ve koronal bölgesine sıcak dolum ile kanal tedavisi tamamlandı. Altı ay sonra kontrole çağırılan hastanın tüm objektif şikayetlerinin geçtiği, alınan radyografilerde periapikal lezyonun kaybolduğu izlenmiştir. Vaka 2: 43 yaşında erkek hasta, sistemik hastalığı bulunmamaktadır. Hastadan alınan radyografik görüntülerde 38 ve 37 numaralı dişleri etkileyen dentigeröz kist tespit edildi. 37 numaralı dişin distal kanalında eksternal kök rezorpsiyonu tespit edildi. 37 numaralı dişin distal kanalının tamamı MTA ile dolduruldu, mezial kanallar güta perka ile dolduruldu. 38 numaralı diş çekildi, dentigeröz kist enükle edildi. Üç ve altı ay sonra kontrole çağırılan hastanın tüm objektif şikayetlerinin geçtiği, alınan radyografilerde periapikal lezyon sınırlarının küçüldüğü tespit edilmiştir. Sonuç: Apikal daralımın bozulduğu eksternal kök rezorpsiyonu vakalarında konservatif endodontik tedavinin etkili bir irrigasyon, Ca(OH)2 medikaman ve MTA’nın apikal tıkaç ile birlikte uygulanması başarılı görülen tedavi seçenekleri arasında yer almaktadır.
