Seven rats served as the baseline control. Seven animals received TX (20 mu g/kg bodyweight/day) and seven DX (1.2 mg/kg bodyweight/day), by means of a mini-osmotic pump implanted subcutaneously. Seven rats were separated as a sham, in order to evaluate the pure effect of the surgical procedure on the animals- health. Tooth movement (TM) was achieved with a continuous force of 50 g by placing Elgiloy coil springs between the right maxillary first molar and incisors for 14 days. The animals were sacrificed and specimens containing the appliance and maxillary tooth-bearing segments were processed for light microscopy. The surface area of root resorption lacunae was measured histomorphometrically using digital photomicrographs. To evaluate the resorptive changes on the molar root surface of each group, scanning electron microscopy (SEM) examinations were also carried out. Statistical evaluation of root resorption percentages was performed using Kruskal-Wallis analysis of variance test. Multiple comparisons were determined by the Student-Newman- Keuls method. The level of significance was set at P < 0.05.Publication Metadata only Effectiveness of incremental vs maximum bite advancement during Herbst appliance therapy in late adolescent and young adult patients](2019-01-01) Amuk, Nisa Gul; Baysal, Asli; Coşkun, Ramadan; Kurt, GÖKMEN; KURT, GÖKMENIntroduction: The purpose of this research was to compare the effects of Herbst appliance therapy using incremental vs maximum advancement in late adolescent and young adult patients with Class II skeletal malocclusion. Methods: Forty-two patients with skeletal Class II malocclusion were treated with cast-splint Herbst appliances. The subjects were randomly allocated into 2 groups according to activation type: incremental advancement (IA) and maximum advancement (MA). Initial forward movement in the IA group was 4 to 5 mm and was followed by subsequent bimonthly advancements of 2 mm. Single-step advancement was achieved in the MA group until an edge-to-edge incisor relationship or an overcorrected Class I molar relationship was obtained. Total treatment times were 9.7 +/- 1.1 months for the IA group and 9.5 +/- 1.1 months for the MA group. Dental, skeletal, and soft tissue measurements were performed on lateral cephalograms taken just before and at the end of the Herbst appliance therapy. Statistical significance was set at P <= 0.05. Results: All mandibular skeletal dimensions increased, and improvements of the sagittal maxillomandibular parameters were found in both groups. Protrusion and proclination of the mandibular incisors were greater in the IA group (95.90 degrees +/- 5.34 degrees) compared with the MA group (92.04 degrees +/- 7.92 degrees). Other dentoalveolar changes in both groups were intrusion of the maxillary first molars, and extrusion of the mandibular first molars and maxillary incisors. The mentolabial sulcus was flattened, soft tissue convexity was reduced, and forward movement of mandibular soft tissues was seen after Herbst therapy. Conclusions: Similar skeletal, dental, and soft tissue changes were obtained in both groups after Herbst therapy. Greater proclination and more protrusion of the mandibular incisors were found in the IA group.Publication Metadata only Effects of cell-mediated osteoprotegerin gene transfer and mesenchymal stem cell applications on orthodontically induced root resorption of rat teeth(2017-06-01T00:00:00Z) Amuk, Nisa Gul; Kurt, GÖKMEN; Baran, Yusuf; Seyrantepe, Volkan; Yandim, Melis Kartal; Adan, Aysun; Demir, Secil Akyildiz; Kiraz, Yagmur; Sonmez, Mehmet Fatih; KURT, GÖKMENAim: The aim of this study is to evaluate and compare therapeutic effects of mesenchymal stem cell (MSCs) and osteoprotegerin (OPG) gene transfer applications on inhibition and/or repair of orthodontically induced inflammatory root resorption (OIIRR).Publication Metadata only Effects of Photobiomodulation and Ultrasound Applications on Orthodontically Induced Inflammatory Root Resorption; Transcriptional Alterations in OPG, RANKL, Cox-2: An Experimental Study in Rats(2018-12-01) Amuk, Nisa Gul; Kurt, GÖKMEN; Güray, Enis; KURT, GÖKMENObjective: The aim of this study was to evaluate and compare the reparative and inhibitory effects of a light-emitting diode-mediated photobiomodulation (PBM) and of a low-intensity pulsed ultrasound (LIPUS) on orthodontically induced inflammatory root resorption (OIIRR). Materials and methods: Forty-nine Wistar rats were divided into four groups: untreated group (negative control), group treated with orthodontic appliances (positive control), PBM-treated group (wavelength: 618 nm, output power density: 20 mW/cm(2)), and LIPUS-treated group (frequency: 1.5% +/- 5% MHz, pulse repetition ratio: 1.0% +/- 10% kHz, effect area: 3.88% +/- 1% cm(2) and intensity: 30% +/- 30% mW/cm(2)). OIIRR was induced experimentally in rats for 14 days with an applied force of 100g, and therapeutic approaches were performed concurrently. At the end of the experiment, upper first molar teeth of rats were prepared for genetic analysis, scanning electron microscopy, hematoxylin and eosin staining, and tartrate-resistant acid phosphatase staining. Kruskal-Wallis and post hoc Dunn-s tests were performed. Results: Number of osteoclasts (p < 0.01), number of resorption lacunae and resorption area ratio (p < 0.001) decreased and number of total cells (p < 0.001) increased with the PBM and LIPUS applications when compared with the positive control group. Receptor activator of nuclear factor kappa B ligand (RANKL) levels of PBM and LIPUS groups were lower (p < 0.001), and osteoprotegerin (OPG) levels were higher (p < 0.001) than the positive control group. Cyclooxygenase-2 (Cox-2) expression significantly decreased with LIPUS and PBM administrations (p < 0.05). No significant difference was observed among PBM and LIPUS groups. Conclusions: PBM and LIPUS applications showed marked inhibitory and reparative effects on OIIRR by modulating the OPG/RANKL ratio, Cox-2 expression, and cell differentiation of osteoblasts and osteoclasts.Publication Metadata only Rapid Tooth Movement and Orthodontic Treatment Using Dentoalveolar Distraction (DAD)(2010-05-01T00:00:00Z) Kurt, GÖKMEN; Iseri, Haluk; Kisnisci, Reha; KURT, GÖKMENThe purpose of this report is to describe the dentoalveolar distraction (DAD) technique and to present its effects on the surrounding structures by presenting a Class II case. A 15-year-old skeletal and dental Class II female patient with an overjet of 9 mm was treated by DAD osteogenesis. A custom-made, rigid, tooth-borne intraoral distraction device was used for rapid canine retraction. Osteotomies surrounding the canines were made to achieve rapid movement of the canines within the dentoalveolar segment, in compliance with distraction osteogenesis principles. The amount of canine retraction was 7.5 mm in 12 days at a rate of 0.625 mm per day, with no posterior anchorage loss. The canine teeth showed 1.6 mm extrusion and 11 degrees inclination change (distal tipping) during the same period. Orthodontic treatment continued for 6 months with no clinical and radiographic evidence of complications such as root fracture, root resorption, ankylosis, and soft tissue dehiscence. The DAD technique is an innovative method, because it reduces overall orthodontic treatment time by about 50%, with no unfavorable effects on periodontal tissues and surrounding structures and with no need to use any intraoral or extraoral anchorage app iances.

The aim of this study was to develop a three-directional bone-borne distractor that would allow the transverse expansion and sagittal advancement of the maxilla simultaneously.Publication Metadata only Combined Orthodontic and Surgical Therapy for a Deeply Impacted Third Molar Related with a Dentigerous Cyst(2015-03-01T00:00:00Z) Celebi, Nukhet; Canakci, Gulfesan Y.; Sakin, Caglar; Kurt, GÖKMEN; Alkan, Alper; KURT, GÖKMEN; ALKAN, ALPERThe dentigerous cysts are the common cause that inhibits the eruption of the teeth. Large dentigerous cysts can cause pathological fractures in mandible. Temporary or permanent inferior alveolar and lingual nerve damage can occur associated with deeply impacted third molar surgery. We treated the dentigerous cyst arised from deeply impacted mandibular third molar with orthodontic extraction combined with the marsupialization therapy. This orthodontic-surgical procedure reduced the risk of nerve damage and pathological fracture of the mandible.
