Relationship between voice function and skeletal effects of rapid maxillary expansion

OBJECTIVE To evaluate the effects of rapid maxillary expansion (RME) on the vocal quality, maxillary central incisors, midpalatal suture, and nasal cavity in patients with maxillary crossbite. MATERIALS AND METHODS Coronal CT scans of 30 subjects (14 boys, 16 girls; mean age, 12.01 ± 0.75) were taken before RME (T0), and at the end of the expansion phase (T1). Voice samples of all patients were recorded with a high-quality condenser microphone (RODE NT2-A) on a desktop computer at T0 and T1. Statistical analyses were performed using a paired-sample t-test. The degree of association between the changes in the voice parameters and nasal width was assessed with Pearsons correlation. RESULTS RME treatment produced a significant increase in the transverse dimensions of the midpalatal suture and nasal cavity between T0 and T1 ( P < .05). The maximum F0 and jitter (%) results were shown to decrease statistically significantly from T0 to T1 ( P < .001 and P = .042, respectively). Between T0 and T1, shimmer (%) and shimmer (dB) exhibited statistically significant increases ( P = .037 and P = .019, respectively). CONCLUSIONS After RME therapy, voice quality differences were found to be associated with increases in nasal width.

ORTODONTİDE KAYIT: RADYOGRAFİ VE MODEL

OZET Ortodontide hastalarin tedavisine baslanmadan once mevcut malokluzyonun tanimlanmasi, dogru teshisin konulmasi, uygun tedavi protokolunun belirlenmesi ve tedavi sonuclarinin degerlendirilmesinde, tam ve dogru bir kayit alinmasi onemli yer tutar. Radyografik goruntuleme teknikleri ve hastalardan elde edilen modeller, kayit protokolunde onemli yer tutmaktadir. Bu calismanin amaci guncel radyografi ve modelleme teknikleri hakkinda bilgi vermektir. Anahtar Kelimeler: Ortodonti; Radyografi; Model ABSTRACT It is important to obtain accurate and correct record for identification of the existing malocclusion before starting the treatment of patients in orthodontics, to set the correct diagnosis, to determine the appropriate treatment protocol and in the evaluation of treatment outcomes. Radiographic imaging techniques and models derived from the patient have an important place in the recording protocol. Purpose of this study is to provide information on current radiography and modeling techniques. Key Words: Orthodontics; Radiography; Model

Evaluation of inflammation during fixed orthodontic treatment

OBJECTIVE The aim of this study was to assess effects of fixed orthodontic therapy on high-sensitivity C-reactive protein (hs-CRP) level, CBC parameters and levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT), gamma glutamyl transferase (GGT), alkaline phosphatase (ALP), urea, creatinine, sodium (Na), potassium (K), calcium (Ca), total protein (TP), and albumin (Alb). DESIGN Blood samples (7ml) were drawn at baseline, on days 1 and 7, and three months after placement of braces in the study group, while only one blood sample was drawn at baseline in the control group. Serum hs-CRP levels were measured by nephelometric method. Friedman two-way variance analysis was used to assess values with skewed distribution obtained at baseline, on days 1 and 7, in the third month. Wilcoxon rank sign test was performed if median values were unequal. RESULTS During measurement periods, there were significant increases in hs-CRP level, WBC count and neutrophil count while a significant decrease in Na level (p<0.05). K level was significantly decreased on the day 1. No significant differences were detected in other biochemical parameters evaluated. CONCLUSION Elevation in serum hs-CRP levels and neutrophil: lymphocyte ratio within first 3 months indicates that a systemic immune response develops against therapy in patients undergoing fixed orthodontic therapy.

Diagnosis and presurgical orthopedics in infants with cleft lip and palate

Cleft lip and palate are one of the most common congenital craniofacial malformations. While preoperative treatment for infants with cleft lip and palate is still a scientific debate, patients with this malocclusion usually have to be treated from infancy to adulthood. Orthodontist plays an important role in the treatment of patients with cleft lip and palate. The purpose of this review is to give information about cleft lip and palate and presurgical nasoalveolar molding.
