Abstract

Amaç: Bu çalışmanın amacı, kapanışı olmayan dişlerde uzama, dönme ve devrilme
sıklığı ile oklüzal girişimler ve molar dişlerin uzaması ile temporomandibuler
düzensizlikler (TMD) arasındaki ilişkinin belirlenmesidir.

Gereç ve Yöntemler: Çalışma grubu posterior diş kaybı ile başvuran 191 hastadan oluşmuştur. Bu
dişlerin (462 molar diş) uzama, dönme ve devrilme kayıtları incelendi. Diş
kaybı ve TMD belirtileri saptandı. Bağımsız değişkenler karşılaştırılması için
Ki-kare testi ve Fisher kesin olasılık testi kullanılmıştır. TMD için Pearson korelasyon
yaygınlık parametreleri kullanıldı.

Bulgular:  291 azı dişinde, uzama belirtisi
gözlemlenmedi. 119 azı dişinde, hafif uzama, 52 azı dişinde, orta ve şiddetli
uzama görüldü. 184 azı dişinde, dönme belirtisi görülmedi, 203 molar dişte, 150 den
daha az, 75 dişte ise 150 den fazla dönme tespit edildi.  274 dişte devrilme gözlenmezken, 108 dişte 150
den az devrilme ve 80 dişte ise 150 den fazla devrilme gözlemlendi.
TMD ortalama skorları ile genç yaş grubu ve cinsiyet (kadın) istatistiksel
olarak anlamlı olarak bulundu (Yaş: P < 0.05. Cinsiyet: P < 0.001).

Sonuç: Azı dişlerinde dönme bulgusu daha çok maksillada iken, uzama ve devrilme
bulgusu daha çok mandibulada saptanmıştır. TMD ve diş kaybı belirtileri
arasında anlamlı sonuçlar bulunmuştur, ancak bu sonuçlar molar destek kaybının,
TMD hazırlayıcı faktörleri arasında olduğunu desteklemektedir.

A study of the incidence of overeruption, rotation, tipping in unopposed molars and temporomandibular disorders

Abstract

Aim: The purpose of this study was
to determine the incidence of overeruption, rotation and tipping in unopposed
posterior teeth and study the association among temporomandibular disorders
(TMD).

Material
and Methods: The study group consisted of 191 patients with
posterior tooth loss. These teeth (462 molars) overeruption, rotation and
tipping records were reviewed. Tooth loss and
TMD symptoms were detected. In order to compare the variables Chi-square tests
and Fisher’s exact probability test were used. For TMD, Pearson correlation
prevalence parameters were used.

Results: 291 molars showed no
signs of overeruption. 119 molars showed slight, 52 molars had erupted moderate
to severe eruption. 184 molars had no signs of rotation, 203 were rotated less
than 15°, while 75 molars were rotated more than 15°. 274 molars showed no
signs of tipping whereas, 108 had tipping less than 15°, and 80 molars had
tipping of greater than 15°. Younger age group and
female gender were found to be statistically significant regarding mean scores
of TMDs
(Age: p<0.05, Gender: p<0.001)

Conclusions:
 Molar
rotation was more frequent in the maxilla; whereas overeruption and tipping
were more common in the mandible Significant associations between the signs of
TMD and tooth loss were found, but the current results does not support the
concept that loss of molar support is an etiologic factor in TMDs.
