Thermoplastic Feeding Appliance

A newborn male, aged 5 days, was referred to our clinic with the complaint of nasal regurgitation during bottle feeding. An isolated cleft soft palate was observed during intraoral examination. To assist feeding, the use of a feeding appliance was planned. A feeding appliance was constructed from soft and hard thermoplastic materials. The thermoplastic appliance facilitates feeding and was easily tolerated. Gag reflex was not observed although the appliance extended posteriorly. The patient achieved the desired weight gain sufficient for general anaesthesia within twelve weeks

Giant size abdominal aortic aneurysm repair using open proximal anastomosis under hypothermic circulatory arrest: A report of two cases

Hypothermic total circulatory arrest and open proximal anastomosis techniques are not commonly used in abdominal or juxtarenal abdominal aortic aneurysm repair. Proximal aortic clamping is usually adequate for surgical repair of abdominal aortic pathologies. We present two cases of giant-sized abdominal aortic aneurysms, one was juxtarenal and one was a Crawford type IV thoracoabdominal aneurysm, that were repaired by using open proximal anastomosis under hypothermic total circulatory arrest and a transabdominal approach. This technique may be useful for both thoracoabdominal and large abdominal aortic aneurysms because it offers the opportunity to not clamp the aorta and operate in bloodless surgical field

Comparison of the Shear Bond Strengths of Ceramic Brackets Using Either a Self-Etching Primer or the Conventional Method after Intracoronal Bleaching

Objective:To evaluate the initial shear bond strengths (SBSs) of ceramic brackets using either a self-etching primer (SEP) or the conventional method (CM) after intracoronal bleaching with sodium perborate and distilled water.Methods:Eighty human incisors were divided into four groups according to bleaching and bonding procedures: Group 1, bleaching was not applied and the brackets were bonded with a self-etching primer; Group 2, bleaching was not applied and the brackets were bonded with the conventional method; Group 3, intracoronal bleaching with sodium perborate was applied for three weeks and the brackets were bonded with a self-etching primer; and Group 4, intracoronal bleaching with sodium perborate was applied for three weeks and the brackets were bonded with the conventional method. A self-etching primer (Transbond Plus) was applied as recommended by the manufacturer. After SEP application, the ceramic brackets were bonded with a light-curing adhesive (Transbond XT). For the conventional method, the teeth were etched with 37% phosphoric acid. After etching, a thin uniform coat of primer (Transbond XT Primer) was applied and the ceramic brackets were bonded with a light-curing adhesive (Transbond XT). SBSs were measured after water storage for 30 days, after 1000 cycles of thermocycling between 5°C and 55°C. Bond failure location was determined with the Adhesive Remnant Index (ARI).Results:For the SEP method, there was no significant difference between SBS values of the bleaching and non-bleaching groups. Furthermore, for the conventional method, the SBS value of the non-bleaching group was not significantly different from that of the bleaching group. SBS values of the SEP method presented significant differences from those of the conventional method (p<0.001). SBS values of SEP application decreased with and without bleaching. The ARI scores did not show any significant difference among the groups (p=0.174).Conclusion:Intracoronal bleaching with sodium perborate and distilled water did not affect the SBS values of ceramic brackets

Comparison of Shear Bond Strengths of Ceramic Brackets Using Either Self-etching Primer or Conventional Method After Intracoronal Bleaching

WOS: 000439315100003Objective: To evaluate initial shear bond strengths (SBSs) of ceramic brackets using either a self-etching primer (SEP) or the conventional method (CM) after intracoronal bleaching with sodium perborate and distilled water. Materials and Method: Eighty human incisors were divided into 4 groups according to bleaching and bonding procedures: group 1, bleaching was not applied and brackets were bonded with SEP; group 2, bleaching was not applied and brackets were bonded with the CM; group 3, intracoronal bleaching with sodium perborate was applied for 3 weeks and brackets were bonded with SEP; group 4, intracoronal bleaching with sodium perborate was applied for 3 weeks and brackets were bonded with the CM. The SEP (Transbond Plus) was applied as recommended by the manufacturer. After SEP application, ceramic brackets were bonded with light cure adhesive (Transbond XT). For the CM, the teeth were etched with 37% phosphoric acid. After etching, a thin uniform coat of primer (Transbond XT Primer) was applied and ceramic brackets were bonded with light cure adhesive (Transbond XT). The SBSs were measured after water storage for 30 days, after 1000 cycles of thermocycling between 5 degrees C and 55 degrees C. Bond failure location was determined with the adhesive remnant index (ARI). Results: For the SEP method, there was no significant difference between the SBS values of the bleaching and nonbleaching groups. Furthermore, for the CM, the SBS value of the nonbleaching group was not significantly different from that of the bleaching group. The SBS values of the SEP method presented significant differences from the SBS values of the CM (p < 0.001). The SBS values of the SEP application decreased with and without bleaching. ARI scores did not show any significant difference between the groups (p = 0.174). Conclusion: Intracoronal bleaching with sodium perborate and distilled water did not affect the SBS values of ceramic brackets

The Assessment of Personal Awareness of Malocclusion in a Group of 9 to 12 Year Old Children

The aim of this study was to assess personal and parental awareness of malocclusion in children and to examine whether agreement existed between children and their parents on these assessments. 68 patients (32 girls, 36 boys) applied to our clinic were included in this study. Six traits of the anterior segments (maxillary diastemas, upper and lower crowding and protrusions, and overjet were examined on the orthodontic models. The levels of personal awareness were measured with the comparison of the answers of the subjects and the six traits recorded from the orthodontic models. The polaroids of the anterior teeth of subjects were also used on the assessments. The polaroid of a patient was randomly placed in a panel of 17 alternative photographs. Then the subject and parents were asked on separate occasions to identify his or her polaroid in a series of five attempts. A low level of awareness was found for the children and the parents. About half of the children and the parents identified the child's photograph on the second attempt. There were only three subjects who give correct answers to 5 questions while no subjects correctly reported for all six traits. The agreement across the investigators, child, and parental assessments varied for the six traits in the different malocclusions
