Publication Open Access A minimally invasive transfer method of mesenchymal stem cells to the intact periodontal ligament of rat teeth: a preliminary study(2018-01-01) GÜL AMUK, NİSA; KURT, GÖKMEN; YANDIM KARTAL, MELIS; ADAN, AYSUN; BARAN, YUSUF; KURT, GÖKMENThe aim of this study was to introduce a minimally invasive procedure for mesenchymal stem cell (MSC) transfer into the intact periodontal ligament (PDL) of the molar teeth in rats. Ten 12-week-old Wistar albino rats were used for this preliminary study. MSCs were obtained from bones of two animals and were labeled with green fluorescent protein (GFP). Four animals were randomly selected for MSC injection, while 4 animals served as a control group. Samples were prepared for histological analysis, Cox-2 mRNA expression polymerase chain reaction analysis, and fluorescent microscopy evaluation. The number of total cells, number of osteoclastic cells, and Cox-2 mRNA expression levels of the periodontal tissue of teeth were calculated. The number of total cells was increased with MSC injections in PDL significantly (P < 0.001). The number of osteoclastic cells and Cox-2 mRNA expression were found to be similar for the two groups. GFP-labeled MSCs were observed with an expected luminescence on the smear samples of the PDL with transferred MSCs. The results of this preliminary study demonstrate successful evidence of transferring MSCs to intact PDL in a nonsurgical way and offer a minimally invasive procedure for transfer of MSCs to periodontal tissues.Publication Metadata only The effects of different desensitizer agents on shear bond strength of orthodontic brackets after home bleaching: an in vitro study(2018-05-01T00:00:00Z) GÜL AMUK, NİSA; BAYSAL, ASLI; ÜSTÜN, YAKUP; KURT, GÖKMEN; KURT, GÖKMENPublication Metadata only Ortodontik olarak İndüklenmiş İltihabi Kök Rezorpsiyonu Oluşumu ve Tamiri(2017-12-01T00:00:00Z) GÜL AMUK, NİSA; KURT, GÖKMEN; KURT, GÖKMENPublication Metadata only Ortognatik Cerrahi Planlamasında Okluzal Düzlem Değerlendirmesinin Önemi(2017-12-01T00:00:00Z) GÜL AMUK, NİSA; KURT, GÖKMEN; KURT, GÖKMENPublication Open Access Effects of High-Energy Curing Lights on Time-Dependent Temperature Changes of Pulp Space During Orthodontic Bonding(2019-03-01T00:00:00Z) GÜL AMUK, NİSA; KURT, GÖKMEN; ER, ÖZGÜR; ÇAKMAK, GÜLŞEN; ASLANTAŞ, VEYSEL; KURT, GÖKMENObjective: The purpose of this study was to assess the temperature changes and cooling times during orthodontic bonding by a light-emitting diode (LED) and plasma arc lights (PAC) in different time and power modes with thermal imaging. Methods: A total of 100 human permanent upper first premolar teeth were included in the study. Five groups were conducted, 20 teeth each, and different energy outputs of curing lights were used for adhesive polymerization with different exposure times. The temperature changes in the pulp space and cooldown times were measured by a thermal imaging system. A paired t-test, analysis of variance (ANOVA), and Student-Newman-Keuls multiple comparison tests were used for data analysis. Results: A statistically significant temperature rise was detected with all curing lights (p<0.05). The greatest temperature changes were observed in the LED standard mode with 10 seconds of exposure time (6.66±1.98°C) and LED extra power mode with 6 seconds of exposure time (6.50±1.64°C) among groups, while using PAC for 3 seconds created the smallest temperature increase (1.81±0.99°C). An application of the LED extra power mode for 6 seconds exhibited the longest cooldown time (205.91±47.48 seconds), and the shortest cooldown time was detected as 71.30±43.15 seconds with the PAC 3-second application. Conclusions: LED lights with an increased exposure time induced significant temperature rises, while no PAC light group exceeded the critical threshold value. The exposure time is more important than the energy output level of the light-curing system on temperature increments of the pulp chamber.Publication Metadata only Comparison of dental measurements between conventional plaster models, digital models obtained by impression scanning and plaster model scanning(2019-03-01T00:00:00Z) GÜL AMUK, NİSA; KARSLI, EROL; KURT, GÖKMEN; KURT, GÖKMEN
