Ponticulus posticus in a cohort of orthodontic children and adolescent patients with different sagittal skeletal anomalies: a comparative cone beam computed tomography investigation

BACKGROUND The objective of this study was to evaluate the prevalence and characteristics of ponticulus posticus (PP) in groups with sagittal skeletal anomalies in a Turkish population using cone beam computed tomography (CBCT). MATERIALS AND METHODS A total of 181 CBCT images were evaluated according to gender, side and characteristics of PP in the three different sagittal skeletal groups. RESULTS The average age of the patients was 13.88 ± 2.99 years (ranging 8-18 years). The study population consisted of 104 (57.5%) females and 77 (42.5%) males. PP was detected in 66 (36.5%) patients. Unilateral and bilateral PP was identified in 29 (43.9%) and 37 (56.1%) patients, respectively. The prevalence of PP in the atlas vertebrae was found to be higher in males than in females and this was statistically significant (p ≤ 0.05). PP was most frequently detected in class III patients (25, 13.8%). Statistically significant differences between the different sagittal skeletal groups were observed (p ≤ 0.05). CONCLUSIONS Ponticulus posticus is a common anomaly in Turkish populations and is associated with different sagittal skeletal patterns. The highest frequency of PP was found in angle class III patients. (Folia Morphol 2018; 77, 1: 65-71).

15-35 YAŞ ARASI GÜNEY TÜRK POPÜLASYONUNDA GÖMÜLÜ DİŞ SIKLIĞININ DEĞERLENDİRİLMESİ: EPİDEMİYOLOJİK ÇALIŞMA

Amac : Bu retrospektif calismada ucuncu molar disler haric diger dislerin gomulu kalma sikliginin arastirilmasi amaclanmistir. Gerec & Yontem: Bu calismaya 2674 eriskin birey (Erkek/Kadin:1146/1528) (% 42.8/ %57.2) dahil edildi . Hastalarin panoramik radyogramlari gomulu dislerin varligi acisinda uc oral ve maksillofasiyal radyoloji uzmani tarafindan degerlendirildi. Gomulu dislerin; cinsiyet ve cenelerdeki dagilimlarini karsilastirmak icin ki-kare testi kullanildi. P <0.05 istatistiksel olarak anlamli kabul edildi. Bulgular : 135 hastada toplam 167 gomulu dis saptandi. Bunlarin 74’u kadinlarda, 61’i erkeklerde idi. Gomulu dislerin buyuk kismi maksiller kaninlerden olusmaktaydi. Sonuc : Bu epidemiyolojik calisma onceki calismalarla buyuk benzerlikler gostermektedir ve ayni toplumda daha fazla sayida birey uzerinde incelenmesi uygundur.

The effect of chloroform, orange oil and eucalyptol on root canal transportation in endodontic retreatment.

The purpose of the present study was to assess the effect of solvents on root canal transportation in endodontic retreatment. Sixty extracted human permanent mandibular first molars with curved root canals were selected. All of the root canals were prepared using Twisted File Adaptive instruments (SybronEndo, Orange, CA, USA) and filled with gutta-percha and AH Plus sealer (Dentsply DeTrey, Konstanz, Germany) using the cold lateral compaction technique. The teeth were assigned to four retreatment groups as follows (n = 15): eucalyptol, chloroform, orange oil and control. The canals were scanned using cone-beam computed tomography scanning before and after instrumentation. The chloroform group showed a significantly higher mean transportation value than the orange oil and control groups at the 3 and 5 mm levels (P = 0.011 and P = 0.003, respectively). There was no significant difference among the orange oil, eucalyptol and control groups in terms of canal transportation (P > 0.61). The chloroform led to more canal transportation than the eucalyptol and orange oil during endodontic retreatment.

STURGE-WEBER SENDROMU:BİR OLGU SUNUMU

Sturge–Weber Syndrome is rare, nonhereditary, congenital neurocutaneous disease. Leptomeningeal hemanjiom, generally unilateral port wine nevus distributing trigeminal nerve region, ocular abnormally (glaucoma) are some parts of this syndrome. The present paper reports oral findings of a 18 years old female patient with Sturge-Weber Syndrome. Sturge-Weber Syndrome must be taken into account by dentists because of its various oral manifestations
