In this method of assessment cervical vertebrae C2, C3, and C4 are observed and each patient is placed in a cervical vertebrae maturation index (CVMI). Fishman developed a system of hand-wrist skeletal maturation indicators (SMI), using four stages of bone maturation at six anatomic sites. The purpose of this study was to analyze associations between cervical vertebrae maturation index (CVMI) and skeletal maturation index (SMI). The second objective was to determine the reproducibility of the identifications on the lateral cephalograms and hand-wrist films. Lateral cephalometric and left hand-wrist radiographs of 180 untreated subjects (99 girls and 81 boys) aged from 8 to 18 years were obtained from the files of the Marmara University School of Dentistry, Department of Orthodontics. The results of this study indicated th...

Also, advances in orthodontics, particularly in bone biology, tooth movement and mucogingival alterations, have significant clinical implications. The direction and the amount of tooth movement seem to change the position and the dimension of periodontal tissue margin. Lingual tooth movement will result in an increased thickness of the tissue at the labial aspect of the tooth and decreased clinical crown length. On the other hand, alterations in the periodontal tissue during labial movement of the lower incisors, which is a valuable alternative procedure to extraction therapy, are associated with conflicting literature views. Aim of this review is to provide the clinicians with up-to-date information concerning the influence of tooth movement on the mucogingival complex.

METHODS The records of 20 patients who underwent SARME in the clinics of the dental school at Marmara University in Turkey were collected and divided into 2 groups of 10 patients each, according to the surgical protocol followed. Cone-beam computed tomography images before the operation and 3 to 6 months after the end of active expansion were analyzed by 20 linear and 7 angular measurements. The reliability of the 3-dimensional analysis was investigated. RESULTS All transversal measurements in the dentoalveolar and dental levels increased after expansion in both the SARME with pterygomaxillary disjunction and the SARME without pterygomaxillary disjunction groups with no significant differences between them. In the SARME without pterygomaxillary disjunc...

Many treatment options exist for its correction and the aim of this study was to evaluate the clinical effects of reverse curved NiTi arches on anterior open bite treatment in adolescents and to investigate whether true intrusion of molars could be achieved in this special age group. Material and Methods: The study sample consisted of 15 patients (age ranged from 12.2 to 14 years). All presented a high angle skeletal pattern and an anterior open bite. After initial leveling, upper accentuated curve and lower reverse-curve 0.016 × 0.022 inch arch wires were placed, with anterior elastics applied in the canine regions. Cephalometric assessment was carried out on lateral head films taken at the beginning of treatment and on average 3 months after open bite closure was obtained. Results: The upper and lower incisors, the upper and lower first premolars and the upper...

The aim of the present study was to evaluate IAND with subjective tests postoperatively and assess the relationship between three-dimensional measurements of the mandibular canal (MC) and IAND. METHODS Eighteen patients (Mean age: 24.05 ± 5.85 years) treated with BSSO were retrieved from the archive. Subjective tests (light touch, tactile sensitivity, 2-point discrimination, brush-stroke directional discrimination, sharp/blunt discrimination, dental vitality, questionnaire) and three-dimensional measurements related to MC and fixation screws were done postoperatively (on average 20.43 ± 8.76 months after surgery). Statistical significance was set at P < 0.05. RESULTS Subjective test results were found compatible with each other except brush-stroke directional discrimination test. According to the questionnaire, IAND was apparent in all patients immediately after surgery, and recovery after 1 to 2 years was statistically significant (P < 0.05). Preoperative ramus width, medial and lateral cancellous bone lengths, the decrease in MC length, and the presence of screw in MC were not related to IAND (P < 0.05). CONCLUSIONS There is a high incidence of IAND following BSSO, and the subjective tests are efficient to evaluate the disturbance. Spontaneous recovery of the nerve occurs during the follow-up periods. Instead of preoperative measurements of bone thickness, MC length, and the position of fixation screws, the surgical procedure seems to be more important in IAND occurrence.

Therefore, the morphometric evaluation of pharyngeal airway in patients with CLP is crucial. The purpose of this study is to evaluate the pharyngeal airway volumes of patients with CLP who underwent nasoalveolar molding (NAM) and to compare them with a well-matched control group without NAM. The study consisted of 40 patients with CLP divided into 2 main groups (26 with NAM; 14 without NAM) and 4 subgroups (15 unilateral CLP [UCLP] with NAM, mean age: 10.13 ± 1.30 years; 11 bilateral CLP [BCLP] with NAM, mean age: 10.55 ± 1.51 years; 7 UCLP without NAM, mean age: 9.86 ± 1.68 years; 7 BCLP without NAM, mean age: 10.28 ± 1.89 years). Nasopharyngeal, oropharyngeal, and total airway volumes of all the patients were calculated 3-dimensionally with cone-beam computed tomography. There were statistically significant differences in nasopharyngeal volume (P < 0.05) of NAM group compared to control group; however, volumetric differences in oropharyngeal and total pharyngeal airway were not significant (P > 0.05). The amount of nasopharyngeal, oropharyngeal, and total pharyngeal airway size in the BCLP with NAM group was significantly larger compared to BCLP without NAM group (P < 0.05). However, UCLP did not show any significant difference in NAM group (P > 0.05). This study implies that NAM can effectively enlarge the nasopharyngeal airway size in patient with CLP. In addition, the pharyngeal airway volume enlargement is more apparent in BCLP than UCLP individuals.

Methods: In this study, cone-beam computed tomography scans of 21 Class III patients taken before and 3-6 months after orthognathic surgery were used. Twenty-one patients were divided into two groups: "Group I" consisted of 10 patients who had combined maxillary advancement, maxillary impaction, and mandibular setback surgery, and "Group II" consisted of 11 patients who had combined maxillary advancement and mandibular setback surgery. Three-dimensional cone-beam computed tomography images were registered using cranial base superimposition and the changes of the SSO line were examined based on the three-dimensional reconstructed images. Results: Medial displacement of the SSO line was statistically significant on the axial plane in Group II (p<0.05). Comparison of the changes between Groups I and II showed that the amount of displacement of the SSO line in the axial plane in Group II was significantly greater than that in Group I (p<0.05). Conclusion: In cases that have maxillary advancement and mandibular setback surgery, significant medial displacement of the SSO line was observed. There was no significant change in patients who had combined maxillary advancement, impaction, and mandibular setback surgery.

A 19-year-old male patient's chief complaint was the crowding of lower incisors. He had a straight profile with normal upper and lower lip projection. Upper and lower dental midlines were coincident with the facial midline. The patient had Class I molar and canine relationships on both sides. He had Class I skeletal relationship, low angle vertical pattern, and proclined upper and lower incisors. The treatment plan included the extraction of lower right central incisor to resolve the crowding. At the end of 16-month active fixed treatment, lower dental crowding was resolved. At the 5-year follow-up, the patient had a stable occlusion, with the results of the orthodontic treatment maintained.

Methods Electronic database searches of published orthodontic literature (SRs and MAs) were performed. Three research questions were formulated to include articles in the study: 1) What is the interrelation between orthodontic treatment and temporomandibular disorders (TMDs)?; 2) What is the effect of functional treatment on mandibular growth?; and 3) What differences can be found in a comparison of early/two-phase and late/one-phase orthodontic treatment for Class II malocclusion in growing patients? Studies satisfying the inclusion criteria were appraised in terms of their methodology. The tool for the assessment of the methodology used was the Revised-Assessment of Multiple Systematic Reviews (R-AMSTAR). Results A search revealed 10 studies that satisfied our inclusion criteria. R-AMSTAR evaluations ranged between 13 and 44 points (mean ± SD 29.7 ± 9.44). Three SRs were classified as high-quality studies, two of good quality, and five were judged as having fair to low quality methodology. Further analysis of the results was performed and presented in accordance with the conclusions of each study. Conclusions R-AMSTAR is a readily applicable and validated tool for assessing the methodology of a SR. Most of the SRs concerning our research questions were of average quality. Efforts should be made to reduce methodologic flaws.

The banding and debanding groups were each composed of 40 young adult patients. In the banding group, patients were asked to rinse their mouth with chlorhexidine gluconate for 60 seconds just prior to fitting of the bands. In the debanding group, they were asked to use the mouthwash immediately before removal of bands and brackets. In both groups pre- and post-treatment blood samples were obtained with a strict aseptic technique. In the banding group, no bacteremia was detected in the pretreatment sample and 2.5% post-treatment bacteremia was detected in the post-treatment sample. In the debanding group, 2.5% bacteremia was found in both the pre- and post-treatment samples. The prevalence of post-treatment bacteremia found in the present study were compared with the findings of 2 preliminary studies in which the prevalen...
