    Effects of impacted maxillary canines on root resorption of lateral incisors
    (URBAN & VOGEL, 2017) Ucar, Faruk I.; Celebi, Ahmet A.; Tan, Enes; Topcuoglu, Tolga; Sekerci, Ahmet Ercan
    The aim of this study was to analyze the amount of root resorption of maxillary lateral incisors by relating the position, location, and angulation of the impacted canine using cone-beam computed tomography (CBCT). The study sample consisted of panoramic and CBCT radiographs of 46 patients with a unilateral impacted canine (16 males and 30 females; mean age: 19.53 +/- 6.66 and 19.44 +/- 5.77 years, respectively). Sector location and canine angulation were measured in panoramics. All tomographs were obtained using CBCT (NewTom 5G, QR, Verona, Italy) and three-dimensional (3D) reconstructions of the maxillary laterals assessed by Mimics 14.01 image analysis software. Upper lateral incisor volume was smaller on the impacted side (401.95 +/- 83.69 mm(3)) than on the nonimpacted side (433.54 +/- 92.6 mm(3), P < 0.05). There were no significant differences of lateral root resorption volume when comparing the impacted canines being on the labial or palatal sides (P > 0.05), but impacted canine angulation was significantly steeper on the labial side (70.85A degrees) than on the palatal side (46.09A degrees, P < 0.05). The volume of root resorption of laterals when comparing the various positions of the canine in different sectors or canine angulation in 30(o) intervals was not statistically significantly different (P > 0.05). The impacted canines caused root resorption of lateral incisors. The angulation of the canine was steeper on the labial side than on the palatal side but root resorption of adjacent laterals was not different. There were no statistically significant differences in the amount of root resorption of the laterals when the canine was evaluated according to localization and angulation.

    Evaluation of temporomandibular fossa and mandibular condyle in adolescent patients affected by bilateral cleft lip and palate using cone beam computed tomography
    (WILEY-HINDAWI, 2016) Ucar, Faruk Izzet; Buyuk, Suleyman Kutalmis; Sekerci, Ahmet Ercan; Celikoglu, Mevlut
    The purposes of this study were to investigate the position of the mandibular condyle and temporomandibular fossa between the adolescent patients affected by bilateral cleft lip and palate (BCLP) and well-matched controls without any cleft by using cone-beam computed tomography (CBCT). The study sample consisted of 17 patients (7 females and 10 males; mean age, 14.27 +/- 2.83 years) affected by BCLP and 17 patients (6 females and 11 males; mean age, 14.27 +/- 2.12 years) as age-and sex-matched control group without any cleft. Using cone-beam computed tomography segmented three-dimensional temporomandibular fossa and mandibular condyle images were reconstructed and angular, linear, and volumetric measurements of the patients in both sides of the groups were examined using Paired and Student's t-tests. Comparison of the sides showed that both sides were found to be similar in BCLP and control groups, except the condylar angulation of the right side was found to be higher compared to that of the left side in both groups (p<0.05). Comparison of the groups showed that the patients affected by BCLP and non-cleft patients had similar values for all parameters, except for the condylar angulation in the right side (BCLP group had less angulation compared to controls; p<0.05). The condylar volume was found to be slightly less in the BCLP group in both sides compared to the controls (p>0.05). The positions of the mandibular condyle and temporomandibular fossa were found to be similar in patients affected by BCLP and control group of without any cleft. SCANNING 38:720-726, 2016.

    Evaluation of the mandibular volume and correlating variables in patients affected by unilateral and bilateral cleft lip and palate: a cone-beam computed tomography study
    (SPRINGER HEIDELBERG, 2016) Celikoglu, Mevlut; Ucar, Faruk Izzet; Buyuk, Suleyman Kutalmis; Celik, Salih; Sekerci, Ahmet Ercan; Akin, Mehmet
    The aims of the present study were to evaluate the mandibular volume in patients affected by unilateral (UCLP) and bilateral cleft lip and palate (BCLP) and to compare the findings with a well-matched normal occlusion sample without cleft. The study sample consisted of 66 patients divided into UCLP (24 patients; mean age, 14.46 +/- 3.24 years), BCLP (17 patients; mean age, 14.28 +/- 2.85 years), and control (25 patients; mean age, 14.40 +/- 2.81 years) groups. The volume of the mandible including the condyle and the roots of the teeth and craniofacial measurements were performed using cone-beam computed tomography and analyzed using the one-way variance analysis and post hoc Tukey's tests. Regression analyses were used to evaluate the relationships of the measurements and the mandibular volume. Patients affected by UCLP and BCLP had similar craniofacial features (p > 0.05), including decreased SNB, Co-A, Co-Gn, Co-Go, and Go-Gn and increased ANB and SN-MP measurements compared to the control group. Both UCLP and BCLP groups had decreased values of mandibular volume compared to the normal occlusion group, while these differences were found to be statistically insignificant (p > 0.05). Co-Go (Beta = 0.420; p = 0.014) and Co-Gn variables (Beta = 0.708; p = 0.045) were positively correlated with mandibular volume, while SNB (Beta = -0.669; p = 0.044) and SN-MP (Beta = -0.358; p = 0.049) variables were negatively correlated (R (2) = 60.3 and p = 0.000). Mandibular volume insignificantly differs in cleft patients (p > 0.05), and the variables of Co-Go, Co-Gn, SNB, and SN-MP significantly correlate with the volume. This article investigates mandibular volume in patients affected by UCLP and BCLP that has never been investigated in the literature. The present study showed that both UCLP and BCLP groups had insignificantly decreased values of mandibular volume compared to the normal occlusion group.

    Maxillary sinus volumes of patients with unilateral cleft lip and palate
    (ELSEVIER IRELAND LTD, 2015) Erdur, Omer; Ucar, Faruk Izzet; Sekerci, Ahmet Ercan; Celikoglu, Mevlut; Buyuk, Suleyman Kutalmis
    Background and objective: Studies about maxillary sinuses of cleft lip-palate patients have increased since sinusitis is commonly observed in these patients. It is evident that maxillary sinus will be morphologically affected in these patients. And anatomic differences may be a cause or at least a contributor of sinusitis. The aim of this study was to compare maxillary sinus volumes of the non-syndromic patients with unilateral cleft lip-palate and control group by using Cone-Beam computed tomography. Methods: Tomography scans of 44 unilateral cleft lip-palate patients (18 right and 26 left) with age and gender matched 45 control patients were evaluated for the study. The images used in the study were part of the diagnostic records collected due to dental treatment needs. All tomographs were obtained in supine position by using Cone-Beam computed tomography (NewTom 5G, QR, Verona, Italy). The patient-specific Hounsfield values were set to include the largest amount of voxels in the sinuses volume calculation individually. All data were measured in mm(3). Results: There was no statistically difference between the gender and age distributions of the groups. No statistically significant difference was found on the cleft and non-cleft side, the right and left side of the unilateral cleft lip-palate patients and the control group (P > 0.05). For the inter group comparison, mean maxillary sinus volumes volume of unilateral cleft lip-palate patients (9894.55 +/- 4171.44 mm(3)) was statistically smaller than the control group (11,977.90 +/- 4484.93 mm(3)) (P < 0.05). Conclusion: Maxillary sinus volumes were effected negatively in unilateral cleft lip-palate patients when compared with the healthy control group. No difference was found on the cleft, non-cleft side and the right-left side of the unilateral cleft lip-palate patients. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

    Three-dimensional evaluation of the pharyngeal airway volumes in patients affected by unilateral cleft lip and palate
    (MOSBY-ELSEVIER, 2014) Celikoglu, Mevlut; Buyuk, Suleyman Kutalmis; Sekerci, Ahmet Ercan; Ucar, Faruk Izzet; Cantekin, Kenan
    Introduction: Patients affected by cleft lip and palate often have complaints of snoring and respiratory difficulties during sleep. The purposes of this study were to evaluate nasopharyngeal, oropharyngeal, and total airway volumes of patients affected by unilateral cleft lip and palate and to compare them with a well-matched control group without unilateral cleft lip and palate using cone-beam computed tomography. Methods: The study sample consisted of 60 patients (26 girls, 34 boys) divided into 2 groups: unilateral cleft lip and palate (20 boys, 10 girls; 8 right sided, 22 left sided; mean age, 14.6 +/- 6 3.2 years) and no cleft (control group; 14 boys, 16 girls; mean age, 14.8 +/- 62.8 years). Nasopharyngeal, oropharyngeal, and total airway volumes of the subjects in both groups were calculated 3 dimensionally with cone-beam computed tomography. Group differences in relation to cleft side, sex, and cleft presence were statistically tested at P <0.05. Results: Patients affected by unilateral cleft lip and palate had similar airway volumes regardless of the side of the cleft. In addition, no statistically significant differences were found between the sexes in the 2 groups. Patients affected by unilateral cleft lip and palate had smaller nasopharyngeal, oropharyngeal, and total airway volumes when compared with the control group. The difference for oropharyngeal airway volume (-4036.7 mm(3)) was statistically significant (P <0.05), whereas nasopharyngeal volume (-21.6 mm(3)) and total airway volume (-4057.3 mm(3)) differences were not significant (P >0.05). Conclusions: Patients affected by unilateral cleft lip and palate had decreased volumes of oropharyngeal (P <0.05) and total (P >0.05) airways compared with the well-matched control group without unilateral cleft lip and palate.
