Abstract

Background: The immune system of the oral cavity suffers alterations due to fixed orthodontic treatment which act aspotent stimulus for oral secretory immunity. The aims of this study are to estimate the effect of fixed orthodonticappliance on the level of salivary sIgA at different time intervals, and to verify the gender difference.Materials and method: The patient's history, clinical examination, and fixed orthodontic appliances were placed for30 Iraqi orthodontic adult patients had class II division 1 and/ or class I malocclusion (15 males and 15 females) aged18-25 years old. The unstimulated whole saliva was collected from each sample immediately before wearing fixedappliance (control group T0 as base line), and after 2 weeks (T1),1 month (T2), and 1year (T3) of wearing fixedorthodontic appliance. The levels of salivary sIgA were measured by Enzyme Linked Immunosorbant Assay kit (ELISA).Results: The mean value of salivary sIgA was elevated at T1 and reached the peak at T2 followed by declined at T3to reach near the normal value at T0 (base line). Repeated measure ANOVA test showed statistically highlysignificant difference among four time intervals. The Bonferroni test after repeated measure ANOVA test showedhighly statistical significant difference between each two time intervals except between T0 and T3 show significantdifference. In addition there were no significant gender differences.Conclusion: In this study one can conclude that fixed orthodontic appliance acts as an immunological stimulant inthe oral cavity that changes the level of salivary sIgA which evaluate the immunity status in the oral cavity

Abstract

Background: The frontal sinus area can be used as a diagnostic aid to recognize mouth breather subjects. The aimsof this study were to determine the gender difference in each group, to compare the frontal sinus area betweenmouth breather and nasal breather group, and to verify the presence of correlation between the frontal sinus areaand the cephalometric skeletal measurements used in this study.Materials and Methods: Cephalometric radiographs were taken for 60 adults (30 mouth breathers and 30 nasalbreathers) age range (18-25), for each group 15 males and 15 females, in the orthodontic clinic in the college ofDentistry at Baghdad University. The control group (nasal breather) with skeletal class I and ANB angle rangedbetween 2-4º, and have clinically class I occlusion. The cephalometric measurement for each group were taken, thecephalometric radiographs were analyzed by using AutoCAD 2007 program.Results and Conclusions: In comparison to nasal breather the mouth breather has larger Gonial angle giving atendency to posterior rotation with growth of the mandible. The mouth breather has less maxillary length than thenasal breather. No effect of gender in mouth breather on gonial, SNA and SNB angles, no effect of gender in nasalbreather on gonial angle, while the other cephalometric measurements were higher in males than females in eachgroup. The mouth breather showed more anteroposterior extent of anterior cranial base; also the mouth breathershow an increase in all facial height than the nasal breathers, the frontal sinus area is smaller in mouth breather thanin nasal breather. The frontal sinus area showed correlation for both groups (Mouth and nasal breather) with maxillaryLength, mandibular length, ramal length, S-N length, TAFH, UAFH, LAFH, TPFH, LPFH, and UPFH. There is only correlationof frontal sinus with the SNA and SNB angles in nasal breather and no significant correlation for both groups with thegonial angle

Abstract

Background: Complete analysis of facial profile should also include an evaluation of soft tissue morphology.Materials and Method:The sample consisted of 90 Iraqi adults (45 males and 45 females) aged 18-25 years fromBaghdad city divided into 3 groups according to the ANB angle with 30 subjects in each group (15 males and 15females) for class I, II and III. Lateral cephalometric radiograph was taken for each subject and 8 angular and 5linear measurements were identified and determined, t-test, ANOVA and LSD test were used to compare betweenboth genders and between different classes.Results:Showed that females had greater angular measurements and smaller linear measurements with more lipprominence than males in all classes, there was more convex facial profile with more prominent forehead, moreprominent tip of the nose with increased facial heights and more prominent lips in class II subjects than in class I andIIIsubjects.Conclusion: There is wide variation in soft tissue facial profile among different classes of malocclusion and carefuldetermination of the components of soft tissue facial profile is very important in the diagnosis and treatmentplanning
