title: [Analysis of soft tissue thickness in persons with malocclusions of Class II division 1 and Class II division 2].
abstract: BACKGROUND
  Different malocclusions indicate different thickness of facial soft tissue.
  
  
  OBJECTIVE
  The aim of the study was to establish the differences in the thickness of facial soft tissue profile in persons with dentoskeletal Class II/1 and II/2 relationship.
  
  
  METHODS
  In the study we used cephalometric rendgenograms profile analysis of 60 patients aged 12-18 years of the Dental Clinic in Nis who had not previously undergone orthodontical treatment. According to the dentoskeletal jaws relations the patients were divided into two groups with Class II division 1 and Class II class division 2. In all of them the standard dentoskeletal profile analysis by Steiner and soft tissue profile analysis by Burston was done. The obtained findings were statistically analyzed and the comparison between the studied groups was performed.
  
  
  RESULTS
  The results indicated the following: in the patients with Class II/1 relationship there was a significantly thinner upper lip (t=5.741; p<0.0001), thinner upper lip sulcus (t=3.858; p<0.001) and significantly thinner lower lip (t=2.009; p<0.05) in relation to the patients with Class 11/2. Compensatory effect in the Class II/1 patients was more distinctive in females, as their soft tissue profiles were thicker. In Class 11/2 patients this relationship was in favor of males.
  
  
  CONCLUSIONS
  The facial soft tissue profile indicated significant differences in the thickness dependant on the type of malocclusion and gender. Because of their great variability and a significant participation in the formation of the profile, while planning orthodontic therapy, it is necessary to pay them full attention, with obligatory analysis of the dentoskeletal profile.
