Öğe Evaluation of the Facial Soft-Tissue Thickness in Patients With Cleft Lip and Palate(Lippincott Williams & Wilkins, 2019) Erdur, Emire Aybuke; Baka, Zeliha Muge; Fidanboy, Merve; Erdur, OmerAim: In this study the authors aimed to evaluate craniofacial morphology and facial soft tissue thickness of the patients with cleft lip and palate.(CLP), and to compare the results with a sex and age-matched noncleft healthy control group. Methods: Craniofacial and soft tissue thickness measurements of 20 patients with unilateral cleft lip palate (UCLP) and 20 patients with bilateral cleft lip palate (BCLP) were compared with 20 noncleft control subjects. Angles between Sella-Nasion-A point, Sella-Nasion-B point, Nasion-A and Nasion-B line, Sella-Nasion line and Gonion-Gnation line, and linear (glabella, rhinion, subnasale, labrale superius, stomion, labrale inferius, labiomentale, pogonion, and gnathion) measurements were assessed on lateral cephalometric radiographs. Group differences were evaluated with 1-way analysis of variance and post hoc Tukey test. Results: Unilateral cleft lip palate and BCLP groups demonstrated lower values of skeletal measurements than control group except for Sella-Nasion line and Gonion-Gnation line value (P< 0.01). Maxillary incisors were retruded in BCLP group compared with the other groups (P< 0.001). Thickness of the rhinion, subnasale, and stomion demonstrated no significant difference between UCLP and BCLP groups (P> 0.05). Thickness of rhinion and stomion was found significantly higher in both groups, and thickness of the subnasale was found significantly lower than the healthy group (P< 0.05). Conclusion: Findings of the study suggested that patients with CLP showed differences on craniofacial morphology and facial soft tissue thickness. Before planning orthodontic treatment and esthetic surgeries, soft tissue thickness should be taken into consideration in addition to skeletal measurements in CLP patients.Öğe How effective is a thick plate on stabilisation in 10 mm mandibular advancement?(Churchill Livingstone, 2022) Esen, Alparslan; Menziletoglu, Dilek; Erdur, Emire Aybuke; Akkulah, SebnemWe compared the stability and stress analysis of four different fixation methods after sagittal split ramus osteotomy (SSRO) in mandibular models. In the first model (1P1B) we adapted a four-hole, 2.0 mm standard miniplate on the osteotomy line with one bicortical screw at the top. In the second (2P) we placed two four-hole 2.0 mm standard miniplates above and below the osteotomy line. In the third (3B), we applied three inverted L-shaped bicortical screws, and in the last (1RP1B) we used a four-hole miniplate with increased thickness on the osteotomy line with one bicortical screw at the top. A static vertical load of 200 Newtons (N) was then applied to each model from the occlusal of the first molar. The maximum and minimum principal stresses on the bone were observed more in the proximal segment close to the osteotomy line in all groups. Maximum von Mises stresses were 2705.21 Megapascals (MPa), 1633.56 MPa, 1121.4 MPa, and 1734.44 MPa for the 1P1B, 2P, 3B, and 1RP1B groups, respectively. Displacement values were 1.92 mm, 1.15 mm, 0.79 mm, and 1.42 mm for the 1P1B, 2P, 3B, and 1RP1B groups, respectively. The reinforced plate contributed to the stabilisation, but it was not as effective as three bicortical screws and a double plate. (C) 2021 The British Association of Oral and Maxillofacial Surgeons.

We presented a case who experienced gingival bleeding when risperidone dose was increased to 0.5 mg/day, and subsided after decreasing the dose to 0.25 mg/day, suggesting a dose-dependent side-effect. The bleeding side effect of risperidone might be caused by several mechanisms, including 5-hydroxytryptamine 2A receptor antagonism. Although bleeding associated with risperidone is rarely reported, clinicians should be aware of this side effect.Öğe To: Editor, The Angle Orthodontist Re: Response to: The effect of platelet-rich fibrin (PRF) on maxillary incisor retraction rate.

The objectives of this study were to quantitatively measure temporomandibular joint (TMJ) disk stiffness in adolescents with bruxism using shear wave elastography (SWE) and to examine the relationship between elastography values, patient age, and duration of bruxism.Study Design. This prospective study evaluated 120 TMJ disks of 60 adolescents (30 patients with bruxism and 30 controls). The stiffness of the anterior, intermediate, and posterior parts of the disk was measured. The patient and control groups' respective quantitative SWE values of elasticity (kilopascals [kPa]) and velocity (meters/second [m/s]) were compared.Results. The elasticity and velocity values of the anterior and intermediate parts were significantly higher in the patients than in the controls (P < .013), with no significant difference in the size of the joint space (P = .886). A receiver operating characteristic anal-ysis resulted in sensitivity for the anterior part of 0.80 for kPa and 0.83 for m/s, with specificity of 0.57 (kPa) and 0.60 (m/s). For the intermediate part, the sensitivity was 0.80 for kPa and 0.86 for m/s, with specificity of 0.64 (kPa) and 0.57 (m/s). No correla-tions were found between the SWE values and patient age (P > .098) or duration of bruxism (P > .134).Conclusions. SWE may be useful in the evaluation of TMJ disk stiffness in patients with bruxism. (Oral Surg Oral Med Oral Pathol Oral Radiol 2022;134:492-499)
