Objectives: Vertical root fracture (VRF) is
one of the complications of endodontic treatment which results extraction of
the related tooth. The purpose of this prospective study was to evaluate
prevalence of VRF in extracted endodontically treated teeth.

Materials and Methods: During a 1 year period 241 teeth
were observed. All of the cases were from extracted teeth after endodontic
treatment. Clinical signs, symptoms, the informations about patient and related
tooth were recorded.

Results: A total of 17 (7.02%) cases of
VRF occurring among 241 cases were observed. The VRF occurred most frequently
in the mesial roots of the mandibular first molars (23.5%) and they were the
most frequently extracted teeth (35.2%). The VRF prevalence of maxillary first
molars was 23.5%, maxillary first and second premolars with a same frequency
(11.7%) were the following most fractured teeth. The fractures were
predominantly buccolingual and were more frequent in female patients (58.8%).
The mean patient age was 36 years and the mean time to VRF was 45 months. Most
of the teeth which undergo VRF had a composite restoration (41.1%). 23.5% of
the teeth had a post restoration and from among these posted teeth 75% were
fully crowned. VRF was found similar frequency in mandibular teeth and in
maxillary teeth (P>0.05).

Conclusions: After average of 45 months from endodontic treatment,
mandibular first molar teeth were found most frequently prone to extraction due
to VRF. Further investigation is necessary to determine the possible causes and
evidence of fracture development.

Endodontik Tedavi Görmüş Çekim Endikasyonu Olan Dişlerde Dikey Kök Kırığı Görülme Sıklığı: İleriye Dönük Bir Çalışma

Amaç: Dikey kök kırığı (VRF), ilgili
dişin çekimini gerektiren, endodontik
tedavinin komplikasyonlarından biridir. Bu ileriye dönük çalışmanın
amacı, çekim endikasyonu bulunan endodontik tedavi görmüş dişler arasında VRF
görülme sıklığını değerlendirmektir.

Gereç ve Yöntem: 1 yıllık bir süre boyunca 241 diş
gözlendi. Tüm vakalar çekim endikasyonu bulunan endodontik tedavi görmüş dişler
arasından seçildi. Hasta ve ilgili diş ile ilgili klinik belirtiler, işaretler
ve bilgiler kaydedildi.

Bulgular: 241 vaka arasında toplam 17
(%7.02) VRF vakası gözlendi. VRF, en sık alt çene birinci büyük azı dişlerin
mesial köklerinde (% 23,5) meydana gelmiş ve bu dişlerin en sık çekilen dişler
olduğu bulunmuştur (%35,2). Üst çene birinci büyük azı dişlerde VRF görülme
sıklığı % 23,5; takiben, üst çene birinci ve ikinci küçük azı dişler aynı
oranla (% 11,7), en sık kırılan dişler olmuştur. Kırıklar ağırlıklı olarak
bukko-lingual idi ve kadın hastalarda daha sıktı (% 58,8). Ortalama hasta yaşı
36 idi ve VRF oluşana dek geçen ortalama sure 45 ay idi. VRF görülen dişlerin
çoğunda kompozit onarım (% 41,1) vardı. Dişlerin % 23.5'inde post restorasyon
vardı ve bu postlu dişlerin % 75'inde tam kron vardı. VRF alt çenedeki dişlerde
ve üst çenedeki dişlerde benzer frekansta bulundu (p>0. 05). Sonuç: Endodontik tedaviden ortalama 45
ay sonra, alt çene birinci büyük azı dişler VRF nedeniyle sıklıkla çekime daha
yatkın bulundu. Kırık gelişiminin olası nedenlerini ve kanıtlarını belirlemek
için daha ileri araştırmalar gereklidir.
