Comparison of Maximum Mouth Opening Capacity in Class I and Class II Division 1 Adolescents

Abstract

The aim of the present study was to determinethe maximum mouth opening capacity in seventyeight Angle Class I and Angle Class II, 1 subjectswho were non-orthodontically treated and symptom-free of any temporomandibular joint TMJ dysfunctions. A standardized clinical examinationand cephalometric evaluations were performed.Maximal mouth opening were measured by using amillimetric ruler. Skeletal structure of the groupswere analysed with the lateral cephalograms.Differences among the groups were evaluated usingt-test. Pearson correlation analysis was used for thecorrelation analysis. Angle Class I subjects hadhigher levels of maximum mouth opening capacitythan subjects with Angle Class II,1 47.77 ± 4.69 vs45.36 ± 5.02 mm, p

SINIF I VE SINIF II, 1 ADOLESAN DÖNEMİ BİREYLERDE MAKSİMUM AĞIZ AÇILIM MESAFESİNİN KARŞILAŞTIRILMASI

Abstract

Bu çalışmada amaç, Angle sınıf I ve Anglesınıf II bölüm 1 kapanışlı, herhangi bir temporomandibuler eklem TME problemi bulunmayan adolesan dönemdeki toplam 78 bireyde maksimum ağ›z aç›kl›ğ› mesafesini değerlendirmektir. Tüm bireylerin klinik muayeneleri yap›ld› ve maksimum ağ›z aç›l›m mesafesinin iskeletsel ölçümlerle ilişkisini tespit etmek amac›yla sefalometrik radyografiler al›nd›. Maksimum ağ›z aç›l›m mesafesi klinikte milimetrik bir cetvel yard›m› ile ölçüldü. Lateral sefalometrik radyografiler üzerinde iskeletsel ölçümler değerlendirildi. Gruplar aras› karş›laşt›rmalarda t-testi kullan›ld›. Ayr›ca Pearson korelasyon analizi kullan›ld›. Angle s›n›f I vakalarda maksimum ağ›z aç›l›m mesafesi Angle s›n›f II bölüm 1 vakalara göre daha yüksek bulundu 47.77 ± 4.69 vs 45.36 ± 5.02 mm, p
