Abstract

Background: Malocclusion is one of the main problems concerning the oral cavity. This study examined the possible effect of mouth breathing habits in patients with respiratory tract allergies on the dental occlusion.Materials and methods: The study was conducted on 150 patients having allergic rhinitis, asthma or both ranging in age from 5-19 years. A group of 150 healthy individuals matched with gender and age to the study group was used as a control group. The total sample was questioned about their mode of breathing then their occlusion was examined clinically.Results: Significantly higher percentages of mouth breathers were found among the study group (P<0.05). Similarly CLII and CLIII dental occlusion, displaced teeth as well as crowding affected significantly greater percentages of allergic patients in comparison to the control group.Conclusion: Mouth breathing habits in patients with respiratory tract allergies may have an additive role in the development of some undesirable malocclusions

Abstract

The purpose of this study was to investigate soft tissueadaptability to hard tissue; in other words, to evaluate the relationbetween the inclination of upper and lower anterior teethwith the upper and lower lips, and how this relation affectthe soft tissue profile in Class II division 1 malocclusion subjectfor both genders (males and females).The sample of this study comprised lateral cephalogramsfrom 40 Class II division 1 malocclusion subjects (20 malesand 20 females) aged 18–25 years. Two dental [upper and lowerincisor inclination {the angle formed between the longaxis of the upper central incisor (U1) and the palatal plane(PP) and the angle formed between the long axis of the lowercentral incisor (L1) and the mandibular plane (MP)}] and threesoft tissue [nasolabial (nla), labiomental (lma) and soft tissuefacial convexity (n–sn–pog)] angular measurements wereanalyzed. The results showed no significant difference betweenmales and females concerning the proclination of upperanterior teeth and the prominency of upper lip, while the femalesexhibited more proclined lower anterior teeth and moreprotrusive lower lip than males. The males tend to have moreconvex facial profile than females

Abstract

A proper relationship of the total mesiodistal width of the maxillary dentition tothat of the mandibular dentition will favor an optimal post treatment occlusion, thepurpose of this study is to obtain information of the mesiodistal crown dentition and toothsize discrepancy in subject with Cl. I Angle malocclusion with spacing in the upper andlower arches. 30 pairs of dental casts were obtained (15 males, 15 females) weremeasured and analyzed, the results indicates no significant difference between right andleft sides, and non significant regarding tooth size analysis ( Bolton ratio) between malesand females, sexual dimorphism was found regarding mesiodistal crown dimension withgreater mean values for males
