ELECTROMYOGRAPHIC ACTIVITY(EMG) OF TEMPORAL AND MASSETER MUSCLES BEFORE AND AFTER FITTING REMOVABLE NEW DENTURES IN OLDER ADULTS

Background and Aim: This study aimed to investigate changes in chewing, maximum clench, swallowing and rest activities of the masseter and anterior temporalis muscles by using electromyography in partial edentulous and edentulous patients, before treatment, day 1, then at week 1 and month 1 of prosthetic rehabilitation. Materials and Method: This study was performed on 36 healthy individuals who have lack of right side posterior teeth (Group 1), lack of double-side posterior teeth (Group 2), an edentulous (Group 3) and those with natural dentition as control (Group 4) (n= 9). Measurements were taken before the delivery of prostheses (with old prosthesis in Group 3), at day 1, then at week 1 and month 1 of prosthetic rehabilitation. Data were analyzed statistically. Results: The highest EMG values were obtained in natural dentition. At the end of 1 month, in the unilateral and bilateral partial edentulous groups, values were seen to be similar albeit still lower than the ones obtained for natural dentition. The lowest EMG values were obtained in patients with complete prosthesis. Conclusion: It can be concluded that at the end of 1 month, activation of the muscles tested approached an effective chewing level in either partial edentulous or edentulous patients.

YENİ HAREKETLİ PROTEZLERİN KULLANIMINDAN ÖNCE VE SONRA TEMPORALİS VE MASSETER KASLARININ ELEKTROMYOGRAFİK AKTİVİTESİ

Amaç: Bu çalışmada protez rehabilitasyonun tedavi öncesi, 1. gün, daha sonra 1. hafta ve 1. ayında elektromiyografi kullanılarak masseter ve anterior temporalis kaslarının çiğneme, maksimum sıkma, yutma ve dinlenme aktivitelerinde değişikliklerin araştırılmasıdır. Gereç ve Yöntem: Bu çalışma sağ taraf posterior dişsiz (Grup 1), çift taraflı posterior dişsiz (Grup 2), tam dişsiz (Grup 3) ve kontrol grubu olarak (Grup 4) doğal dişe sahip olan 36 sağlıklı birey üzerinde yapıldı (n= 9). Ölçümler protezlerin verilmesinden önce (Grup 3’te eski protezle), 1. günde, daha sonra 1. haftada ve protez rehabilitasyonunun 1. ayında yapıldı. Veriler istatistiksel olarak analiz edildi. Bulgular: En yüksek EMG değerleri doğal dişli bireylerde elde edildi. 1 ayın sonunda, doğal dentisyonda en yüksek EMG değerleri elde edildi. 1 ay sonunda, tek taraflı ve iki taraflı kısmi dişsiz gruplarda, doğal dentisyon için elde edilenlerden daha düşük de olsa değerlerin benzer olduğu görülmüştür. En düşük EMG değerleri tam protezi olan hastalarda elde edildi. Sonuç: 1 ayın sonunda, test edilen kasların aktivasyonunun, kısmi dişsiz veya dişsiz hastalarda etkili bir çiğneme düzeyine yaklaştığı sonucuna varılabilir.
