Abstract:
The aim of this review was to evaluate associations between different orthodontic treatment techniques, the role of malocclusion types, and signs and symptoms of temporomandibular disorders (TMDs). Associations between different orthodontic treatment techniques and TMD were found in some studies, whereas most of the reviewed articles failed to identify significant associations. Based on the presently available research, because it has not been demonstrated that malocclusions cause TMDs, it is incorrect to claim that orthodontic approaches can treat or prevent TMDs. Moreover, there is no evidence that any orthodontic treatment causes TMD signs or symptoms. Longitudinal studies are still needed. (Turkish J Orthod 2015;28:71–76)

Abstract:
Objective: The aim of this in vitro study was to compare the effect of a traditional hemostatic agent on the shear bond strength (SBS) of conventional and self-etching bonding systems to find an efficient procedure for orthodontic bonding. Material and Methods: Extracted human premolars (n=108) were divided into 6 equal groups. Conventional light cure primer was used in groups 1, 2, and 3. Acid etching and primer were applied directly in group 1. Enamel surfaces were covered with a Ankaferd Blood Stopper (ABS), which was used as a hemostatic agent in groups 2 and 3. Orthophosphoric acid was applied on ABS-covered enamel in group 2. Before the acid was applied, the enamel surface was cleaned with wet surgical gauze in group 3. A self-etching primer was used in groups 4, 5, and 6. Similar to the first 3 groups, primer was applied on the enamel surface in group 4. Samples were covered with ABS before the primer was applied in groups 4 and 5. The ABS residue was cleaned with gauze before primer application in group 6. The samples were debonded using a universal testing machine. In addition, SBS and residual adhesive were evaluated. Results: Samples contaminated with hemostatic agent and bonded with the self-etching primer without cleaning the hemostatic agent showed significantly lower SBS (p<0.05). Cleaning the ABS on the enamel surfaces increased the bonding strength of self-etching primers. Groups 5 and 6 showed significantly lower ARI scores (p<0.05). Conclusion: Before bonding orthodontic attachments with conventional and light-cure primers, ABS can be safely used. However, using self-etch primers directly on the ABS-applied enamel surface should be avoided.

Abstract:
Objective: 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°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 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.

Abstract:
Objective: No study has investigated the relationship between maxillary sinus findings and skeletal malocclusion based on cone-beam computed tomography (CBCT). The objectives of this study were to determine the relationship between the frequency of sinus findings and patients' skeletal malocclusion classification. Materials and Method: A total of 105 CBCT scans were examined and divided into 3 groups according to skeletal classification. Two experienced observers reviewed the CBCT images and recorded all maxillary sinus findings. The patients' skeletal malocclusion, the thickness of the Schneiderian membrane, and the pathologic sinus findings were evaluated. Results: The sinus findings were classified into 4 groups: 0 = no finding, 1 = mucosal thickening, 2 = partial opacification with liquid accumulation, and 3 = total opacification. The statistical analysis showed that there was no correlation between the skeletal malocclusion and pathological sinus findings. However, there were significant differences in the Schneiderian membrane thicknesses between the groups. Conclusion: The Schneiderian membrane thickness was significantly different for Class II and Class III patients. There was no relationship between pathological sinus findings and skeletal malocclusions.

Abstract:
Transposition of teeth is a rare type of ectopic eruption and in incomplete transposition the crowns might be transposed, but the root apices still remain in their relatively normal positions. In this report, we describe the orthodontic treatment of a 17-year-old girl with mandibular left lateral incisor and canine incomplete transposition in which the involved teeth were repositioned to their normal anatomic position within the dental arch in an acceptable treatment time period. Treatment procedure, mechanics, and sequencing used and final results are described. The final outcome was stable after 18 months of retention. (Turkish J. Orthod. 2015;28:55–63)

Abstract:
A hybrid expander is a newly designed bone-anchored expander consisting of 2 mini-screws and palatal acrylic; it does not cover any teeth. The aim of this case report is to present the treatment of a patient with transversal maxillary deficiency by hybrid expander. An 11.4-year-old female patient came to our clinic complaining about the appearance of her teeth. She had a narrow maxillary arch, unilateral dental crossbite, anterior dental crowding, and dental Class II canine and molar relationships on both sides. Two self-tapping mini-screws were placed between the first molar and second premolar on the palate under minimal local anesthesia. After 1 week, this appliance was bonded to the mini-screws with Transbond XT (3M Unitek, Monrovia, CA, USA) resin. The expansion screw was activated twice a day for 1 week and then once a day until the expansion was completed. After the expansion period, the brackets were bonded to the teeth without removing the hybrid expander. Sufficient maxillary expansion had been achieved without buccal tipping of the posterior teeth, and the midline diastema had closed spontaneously. This newly designed hybrid expander was efficient in correcting a transverse maxillary deficiency without any of the side effects found with conventional rapid maxillary expanders. The most important advantage of this appliance is that clinicians can implement expansion and bonding procedures at the same time. (Turkish J. Orthod. 2015;28:64–70)
