Abstract :Amaç: Üst altı ön dişi kapsayan ortodontik diş hareketinin hem termal hem de elektrikli uyarana karşı pulpa cevabına etkisini aktif ortodontik tedavi ve retansiyonu esnasında değerlendirmektir. Materyal-Metod: Sabit ortodontik tedavi ihtiyacı olan 27 birey çalışma grubu olarak kullanılırken, 27 ortodonti hastası olmayan bireyde kontrol grubu olarak seçildi. Soğuk ve elektrikli uyaran üst kesici ve köpek dişlere sabit apareylerin yerleştirilmesinden hemen önce ve aktif tedavi esnasında düzenli aralıklarla ve retansiyon aşamasında ise 4 ay boyunca uygulandı. Her bir zaman dilimindeki her bir diş için negatif yanıt sayısı her grupta da kaydedildi. Verilerin analizi Mann Whitney-U ve ki kare testleri kullanılarak yapıldı insert ignore into journalissuearticles values(p<0.05);. Bulgular: Kontrol grubunda tüm dişler EPT ve termal pulpa testlerine tüm zaman dilimlerinde pozitif yanıt verdi. Ortodonti grubunda, başlangıçta EPT’ne 2 diş, termal teste sadece 1 diş yanıt vermedi insert ignore into journalissuearticles values(T0);. Bundan sonra, her iki test içinde negatif yanıt sayısı kademeli olarak arttı ve aktif tedaviden 3 ay sonra maksimum değere ulaştı insert ignore into journalissuearticles values(T3); ve sonra test süresinin sonuna doğru kademeli olarak azaldı insert ignore into journalissuearticles values(T6);. Başlangıçta, ortodonti hastalarında EPT yanıt eşiği özellikle de üst yan kesici diş için daha yüksekti. Kontrol grubu için, çalışma süresi boyunca yanıt eşiği göreceli olarak sabitti. Ortodonti grubunda, kuvvetin uygulanması EPT yanıt eşiğini hemen artırıp insert ignore into journalissuearticles values(T1); 2 aydan sonra en yüksek değere ulaştırdı insert ignore into journalissuearticles values(T3); ve sonra kademeli olarak azalttı. Aktif tedavinin sonunda, cevap eşikleri artmış kaldı fakat retansiyon aşamasının sonuna doğru tedavi öncesi değerlere döndü. Sonuç: Diş hekimleri ortodonti hastalarında elektrikli pulpa testi yanıtlarını dikkatli yorumlamalıdır.

Material and Method: Twenty-seven subjects who required fixed orthodontic appliances were used as a study group with 27 non-orthodontic subjects recruited as a control group. Cold and electrical stimuli were applied to the maxillary incisors and canines immediately before and after the placement of fixed appliances and at regular intervals for both groups during active treatment and 4 months into retention. The numbers of negative responses for each tooth at each time interval were recorded for both groups. Analysis of the data were performed by using Mann Whitney-U and chi-square tests insert ignore into journalissuearticles values(p<0.05);   Aim: To investigate the effect of orthodontic tooth movement involving the six maxillary anterior teeth on the pulp response to both thermal and electric stimuli during active orthodontic treatment and retention.

Results: In the control group, all teeth tested positively to the EPT and thermal pulp tests at all time intervals. In the orthodontic group, two teeth failed to respond to EPT and only one tooth to thermal testing at baseline insert ignore into journalissuearticles values(T0);. After that, the number of negative responses to both tests increased gradually at each time interval reac- hing a peak after 3 months of active treatment insert ignore into journalissuearticles values(T3); and then declined gradually towards the end of obser- vation period insert ignore into journalissuearticles values(T6);. At baseline, response thresholds to electric testing were typically higher for orthodontic subjects, particularly for the maxillary lateral incisor tooth. For the control group, the response threshold over the study period was relatively constant. For the orthodontic group, application of force immediately increased the response threshold to EPT insert ignore into journalissuearticles values(T1);, which peaked after 2 months insert ignore into journalissuearticles values(T3); and then gradually redu- ced. At the end of the active treatment, response thresholds remained elevated, but they returned to pre-treatment values towards the end of the retention phase. Conclusion: Dental practitioners should interpret responses to electrical pulp testing cautiously in orthodontic patients . 5);.     Key Words: Dental Pulp; Pulpal Change; Orthodontic Force
