Abstract

Aims: To evaluate the effect of chlorhexidine digluconate rinsing solution on plaque and gingival bleeding in orthodontic patients with fixed appliances. Materials and Methods: This study included 42 orthodontic patients (29 females and 13 males), who were undergoing treatment in orthodontic postgraduate clinic of the collage of Dentistry, Mosul University. The patients of this study had a mean age of 18 years (range 12–28 years). The patients were divided in to control group (brushing only, N=20) and an experimental group (brushing +chlorhexidine digluconate mouth rinse, N=22). Plaque, gingival indices scores, in addition to pocket depth were measured in different three time periods (day 0, two weeks and four weeks). Results: Plaque, gingival indices scores, in addition to pocket depth shows statically significant differences at level (p≤0.05) among different genders between the two groups for each of the three time periods. Conclusions: The use of chlorhexidine digluconate based mouth rinses reduced bacterial plaque accumulation, pocket depth and improved the gingival index

Abstract

Aims: Orthodontic treatment is known as a painful procedure among patients. They feel varying degrees of pain during orthodontic treatment from the stage of initial examination till the end of the treatment. The aims of this study are to explore pain experience among patients undergoing orthodontic treatment with the fixed appliances by comparing two different arch wires sizes. Materials and Methods: The study group consisted of 60 patients (26 males, 34 females) with a mean age of 17.6 years and 20.5 years consequently. Insertion of either 0.014 or 0.016-inch wire was by random selection of patients. Patients were asked to fill out a series of questionnaires for five consecutive days after the insertion of orthodontic initial arch wire, and after the arch wire activation for 4 hours, 6 hours, 24 hours, and till 5 days. The intensity (weak, mild, moderate, severe, and intensive) of the pain symptoms in connection with ten items (Biting on a hard/soft food, sensitive to hot or cold food/drink, mastication of food, fitting anterior and fitting posterior teeth together, cheeks, lips, and tongue pain) have been evaluated. Results: No significant differences were found between age groups, and between the two arch wire groups. Pain perception was more significant in females than in males and the pain perceived at the anterior teeth was greater than posterior teeth. Pain percentage level increased gradually till reaching the peak within 24 hours after the insertion of arch wire and retained the same level in the 2nd day, then decreased till the 5th day. Perceptions of pain by fitting anterior teeth were exactly the same within the period of the first few hours in both arch wire groups, and decreased over the following hours. Conclusion: No age discrimination was found for perception of pain in the two different arch wire groups, with no significant correlation for the time with initial pain that perceived after the insertion of two different initial arch wire sizes then the intensity of pain reduced over the time. Pain was perceived as being greater at the anterior than the posterior teeth and females experienced more pain than males.

Abstract

Aim of the Study: To compare the effects of stainless steel and nickel–titanium closed coil springs with the use of Roth bracket type and different arch wires on the amount of space closure during canine retraction in a Typodont simulation system. Material and Methods: Typodont system with Class II division 1 wax form and set of metal teeth, with Roth stainless steel brackets (0.022×0.030 inch) slot dimension. Eighty stainless steel readymade (Bonwill–Hawley arch form) arch wires divided in to two groups according to the size (0.019×0.025 inch and 0.020 inch), 40 for each size. Forty stainless steel and 40 nickel–titanium closed coil springs with force 200 gm. The distance between the distal wing of canine's bracket and the mesial end of second molar's tube was (31mm) which is the available space. Results: There was a significant difference in the rate of space closure between the two types of arch wires and between nickel titanium and stainless steel closing coil springs. Discussion: The rate of space closure significantly is greater with nickel–titanium closed coil spring. Nickel–titanium closed coil spring produce more sustained light continuous force. Conclusion: Nickel– titanium closed coil spring is an efficient material for canine retraction and space closure even with different wire sizes

Abstract

This study was undertaken to elucidate the effect of fixed orthodontic appliance on the microbial composition of dental plaque and to detect any difference between the isolated microflora from different teeth before and during treatment. Twenty subjects (15 females and 5 males) between (12) and (23) years of age, participated in this study. From each subject, four swabs were collected; two in the anterior region (upper and lower central incisors) and two in the posterior region (upper and lower first molars). Bacterial examinations were performed before the beginning of the treatment and (4-6) weeks after placement of orthodontic appliances, so (160) swabs were collected. The composition of dental plaque determined was under light microscope. The statistical analysis was performed and the results showed a variety of microorganisms from supra-gingival plaque samples in pre-and during treatment fixed orthodontic patient. Changes during treatment consisted of an increase in the Peptpcocci,Klebsiella,α- Streptococci, Pseudomonas and Escherichia coli in certain locations. Conversely, a decrease in the Peptostreptococci,Bacteroids,Veillonella, Staphylococci,Streptococcus mutans, Klebsella, Candida, Lactobacilli and Propeniobacterium in different locations, whereas other microorganisms and some of the above-mentioned microorganisms in certain locations showed insignificant differences.The comparison of microflora between different teeth indicated that the molars presented a significantly more microorganisms than incisors did specially in pre-treatment, whereas the upper incisor in both pre-and during treatment presented more microorganisms than lower incisor; while the lower molar exhibited more microorganisms than the upper molar particularly during treatment.
