Abstract

Aims: To assess the effect of water contamination on the shear bond strength of moisture insensitive Fuji Lc. glass ionomer and to compare it with the shear bond strength of (transbond) light cure composite. Materials and methods: Sixty extracted human premolar were cleaned and dried and embedded in cylinders filled with dental stone and the teeth were divided into three groups (20 teeth of each) which were etched and washed and dried the teeth in group 3 were slightly moistened in a cotton pellet and then the brackets were bonded to the teeth according to the manufacture instructions. Group1: using light cure composite (transbond); Group2: using glass ionomer cement (Fuji Lc.) in dry condition; Group3: using glass ionomer cement (Fuji Lc.) in moist condition. The shear bond strength was measured using instron mechanical test machine. Statistical analysis including descriptive statistics were applied to the results and then the findings were compared among the three groups using ANOVA and Duncan tests. Results: Light cure composite (transbond) had the highest shear bond strength followed by Fuji Ortho. Lc. (moist condition) and then Fuji Lc. (dry condition), which had the significant lowest shearbond strength. Conclusions: Transbond light cure composite had the highest shear bond strength. The presence of moisture enhances the shear bond strength of light cure glass ionomer cement (Fuji Lc.).

Abstract

Aims: The aims of the study were to measure different variables of pharynx in class I and class II skeletal relation, clarify the effect of gender on the pharyngeal measurements and to find the effect of different classes (class I and class II) on the pharyngeal measurements. Materials and Methods: The samples consisted of cephalometric films of 40 subjects, 20 males (10 class I and 10 class II) and 20 females (10 class I and 10 class II). These films were traced and ten linear measurements of the pharynx. Results: No significant difference were noticed between males and females in class I participants except in Ba–PNS (sagittal depth of the bony nasopharynx), PNS–ppw (the sagittal depth of the pharynx along the line ANS – PNS) and hy–MP (millimeter distance from hyoid to the mandibular plane), where males showed a significantly higher value; while males showed a significantly higher value in Ba – ad2 (sagittal depth of the nasopharyngeal airway along line S – Ba) and hy–apw2 (millimeter distance from hyoid to ap2) in class II. Conclusions: No significant differences were noticed between males and females in class I and class II skeletal relation in most of the measured variables and also no significant differences were noticed in the same gender neither in class I nor in class II.

Abstract

Aims: To identify the cephalometric features of three skeletal jaw relations (Class I, II and III).Materials and methods: one hundred thirty four students were selected aged 12–15 years fromsecondary schools in Mosul City, 45 with Class I normal occlusion as control, 44 with Class IImalocclusion and 45 with Class III malocclusion, after taking the lateral cephalometric radiographsaccording to ANB angle. A 20 variables (12 angular and 8 linear) were used in this study to correlatethese variables in the three skeletal Classes. Results: No significant sex differences were observed forthe majority of angular and linear measurements for the three skeletal types. Anterior cranial baselength (S–N) and saddle angle (NSAr) didn’t show significant difference among the three skeletalClasses, the posterior cranial base (S–Ar) was shorter in Class III which indicate the anteriorarticulation of the mandible. The length of maxillary base (ANS–PNS) was longer in Class II thanClass I and III which lead to maxillary prognathism. The body length of the mandible (Go–Pog),effective mandibular length (Ar–Gn) and lower anterior face height was significantly longer inClass III which lead to mandibular prognathism. The SNA angle was significantly smaller in Class IIIthan in the others. SNB and SNPog angles were larger in Class III followed by Class I and then ClassII. The gonial angle (Ar–Go– Me) was larger in Class III which acts to increase mandibular effectivelength. The (N–A–Pog) showed as convex in Class II and concave in Class III. (The U1–PP) angle waslarger in Class II followed by Class I and then by Class III. The (L1–MP) angle in Class II and III wassignificantly smaller than in Class I. Conclusion: Most of the angular and linear measurementsindicated that the skeletal differences between the Class I, Class II and Class III are concentrated within the maxillary and mandibular bases in both the anteroposterior and vertical dimensions and theirtype of articulation. The dental measurements appear to be compensated with that of skeletal one. Alsothese variables showed no significant sex differences in the majority of their measurements

Abstract

Aims: To find the association between different Angle’s classes of malocclusion and to estimate the distribution of hypodontia according to gender, number of missing teeth and the site of the missing teeth. In addition, the heredity role in hypodontia was investigated. Materials and Methods: About 3415 subjects, 1750 females and 1665 males aging between 18–30 years were examined clinically in addition periapical radiographs were taken for each patient to exclude a possibility of impaction. A family history of hypodontia for each patient was taken (for father, mother, brothers and sisters). Then the sample was divided into 3 groups depending on Angle’s classification of malocclusion. Results: No clear association was found between Angle's classes and hypodontia, females showed higher prevalence of hypodontia than males. Family history was obvious in patients with hypodontia. The upper lateral incisor was the most frequent absent tooth. Conclusions: No association was found between Angle’s classification and hypodontia. The upper lateral incisor was the most frequent missing tooth. Maxilla was affected by hypodontia more than mandible. Females were affected more than males with very obvious effect of family history on hypodontia.

Abstract

Aims: The aims of the study are to evaluate the degree of improvement in labiolingual or buccolingual inclination of the teeth after treatment of class II division 1 malocclusion using Roth appliance and to compare the teeth inclination after treatment with that of normal occlusion samples to show if Roth appliance can give a reasonable result with straight arch wire technique. Materials and Methods: A twenty five patients (15–25 years age) with Class II division 1 malocclusion were treated with Roth 22" bracket system after extraction of upper first and lower second premolars to correct molars and canine relation, then the teeth inclination were compared among the four groups on the study casts that were taken before treatment, after treatment, after 1 year retention, and with the control group (25 dental casts of normal Class I occlusion) using special gauge. Results: Significant differences were seen among the four groups in the most of the teeth with the exception of the first molars and upper first premolars with the highest possible value in the(before treatment group). Conclusions: A considerable dispersion around the mean torque measurements was seen in the four groups , more lingual inclination was noticed in distally situated teeth. The preadjusted brackets help in decreasing the labial inclination of the treated teeth in Class II malocclusion making their inclination nearly to control group

Abstract

The aim of the present study was to evaluate the relationbetween crowding, plaque and gingival conditions accordingto the level of dental education of the Iraqi adults.The sample was divided primarily into two groups: Thefirst group was collected from dental students whom dentallywell educated, while the second group was collected fromother population whom dentally non educated (industrialist).Each group was subdivided into two groups according to thepresence or absence of crowding, so that four groups wereobtained (educated participants with non crowded teeth, educatedpersons with crowded teeth, non educated participantswith non crowded teeth and non educated participants withcrowded teeth).The results of this study indicated that the dental educationallevel is positively affecting on the gingival health in bothcrowded and normal occlusion. However, regardless of thelevel of education, plaque accumulation and gingivitis are significantlyhigher in the crowded teeth sample.

Abstract

Aim: To determine the prevalence of white spot lesions in orthodontic patients treated with fixed or-thodontic appliances at different treatment periods and to reveal the teeth most commonly affected by white spot lesions. Materials and Methods: Forty eight patients (31 females and 17 males) treated with fixed orthodontic appliance were included in this study. The patients were examined for the pres-ence of white spot before insertion of the appliance and after its removal using visual examination. Results: This study showed that there was a significant increase in the formation of white spot lesions along with the increase in treatment duration in male group, while females showed no significant dif-ference in white spots at different durations. The first molars were the most affected teeth by white spots followed by canines and second premolars. Conclusion: This clinical study showed that the teeth in buccal segment were affected by white spots more than incisors and the prevalence of white spots increased when the duration of treatment increased.
