Abstract

Background and Aim: Improving esthetics is a major goal in periodontal treatments and specially reconstruction of dental papilla is of great importance. Different techniques have been developed, however the results are not completely predictable. The aim of the present study was to compare the possibility of papilla reconstruction using connective tissue graft with and without Emdogain.

Materials and Methods: In this clinical trial, 40 class II lost interdental papilla (Nordland- Tarnow classification) in 18 patients (4 male and 14 female) were studied. Samples were randomly devided into two groups. Case group was treated by connective tissue graft and emdogain (Straumann-USA) and controls were treated using connective tissue graft only. Periodontal parameters including papilla height (PH), periodontal pocket depth (PPD) and clinical attachment level (CAL) were measured before surgery, and 3 and 6 months after treatment. At the tenth days and 1 month after treatment only the papilla height was measured. Repeated measures analysis was used for data analysis with p<0.05 as the level of significance.

Results: In the control group the mean papilla height changed from 3.38 0.89 to 2.85 0.93 on the 3rd month and 2.90 0.95 on the 6th month. The mean PPD changed from 2.8  0.68 to 2.55 0.70 on the 3rd month and 3.06 1.25 on the 6th month. The mean CAL changed from 3.88 1.29 to 3.79 1.25 on the 3rd month and 4.11 1.44 on the 6th month. In test group the mean papilla height changed from 2.98 0.91 to 2.45 1.55 on the 3rd month and 2.55 1.48 on the 6th month. The mean PPD changed from 2.75 1.49 to 2.63 1.38 on the 3rd month and 2.88 1.39 on the 6th month. The mean CAL changed from 3.75 1.24 to 4.01 1.45 on the 3rd month and 4.28 1.63 on the 6th month. These differences were not significant between the studied groups (P>0.05).

Conclusion: Based on the results of this study, use of connective tissue with or without emdogain is not effective in interdental papilla reconstruction.

Abstract

Background and Aim: Chin cup is an orthopedic appliance for treating growing skeletally Cl III patients. The amount of chin forward movement in addition to morphologic changes in bony structure, determines the final profile of treated patients. The aim of this study was to evaluate the amount of morphologic changes of symphysis after chin cup therapy in skeletally Cl III patients.

Materials and Methods: In this clinical trial, twenty eight cephalometries before and after chin cup therapy of 14 skeletally Cl III patients were analyzed. Landmarks introduced by Ricketts were determined to evaluate the symphysis and describe its relation to mandible. َAlso four additional measurements regarding the symphysis individually were evaluated and analyzed. Data were analyzed by paired t and pearson tests with P<0.05 as the level of significance.

Results: The results showed that the height of symphysis increased after treatment (P=0.02), but its depth decreased (P=0.04). The sysmphysis turned down and back.

Conclusion: These findings suggest that in Cl III malocclusions with a prognathic mandible, chin cup therapy creates changes in the horizontal dimension of symphysis morphology, which improves the Cl III profile. If the patient isn't a vertical grower, vertical changes of symphysis would be desirable. In addition, changes in the vertical dimension of the mandible (body and ramus) could be observed as a backward and downward rotation.


The frequency distribution of factors related to temporomandibular joint disorders in 20-50 year old patients refered to Isfahan dental clinics in 1397

Abstract
Background and Aims: Temporomandibular joint disorders (TMDs) are one of the most common causes of the patient's referral to dental clinics. Considering the role of related factors in its creation, the purpose of this study was to investigate the relative frequency of factors related to temporomandibular disorders in patients aged 20 to 50 years referred to dental clinics in Isfahan in 1397.
Materials and Methods: In this descriptive and analytical study, 324 patients referred to Isfahan dental clinics in 1397 were randomly included. Factors related to TMD and demographic factors of patients were recorded with clinical examination by a trained dentist and self-declaration of patients in the data collection form. The frequency and relevance were analysed by SPSS 22 software and chi-square, fisher and logistic regression statistic tests.
Results: At least one of the TMD related factors was present in 40.7% of the subjects, which the most common factors related to TMD was posterior edentulousness (49.7%). History of jaw dislocation was more common in men (P=0.014) and the frequency of posterior edentulousness was more common in in women (P=0.003). As the age increased, the frequency of posterior edentulousness (P=0.000) and earache (P=0.009) increased. The frequency of posterior edentulousness was higher in housekeepers (P=0.000), the frequency of earache was higher in employees (P=0.005) and the history of jaw dislocation was higher in self-employed persons (P=0.047).
Conclusion: The high prevalence of TMD and related factors, such as a history of jaw dislocation, posterior edentulousness, earache, and clenching, requires attention to be identified and treat these problems.

Abstract
Background and Aims: By using the image processing capability in Cone-Beam Computed Tomography (CBCT), obtained information can be improved. The aim of the present study was to investigate the effect of sharpen image processing filter in determining the external resorption of the root apical region in single-rooted teeth due to the proximity of the impacted tooth using CBCT.
Materials and Methods: In this laboratory study, the lateral surfaces of the apical region of the root of 40 healthy extracted teeth were artificially cut by bur and the teeth were randomly divided into four groups: control, low, moderate, and high resorption. After preparing CBCT of the teeth, the samples were then processed with and without an image sharpening processing filter and examined by two observers. The results of this study were analyzed by SPSS22 and Medcalc Statistical Software version 14. The significance level was considered P≤0.05 for all the statistical tests.
Results: Specificity (100%) and sensitivity (66%>) were either complete or very high for both modes without and with the sharpen filter. The overall accuracy (0.83>) was high in both cases and no significant difference was observed between the two overall accuracies (P>0.05). Statistical analysis of both image observations by two observers showed that the overall sensitivity and accuracy in the medium and high resorption groups was much higher than the low resorption group, but the specificity in all groups was 100%.
Conclusion: The results showed that the images with a sharpening filter did not increase the detection power compared to the unfiltered images. However, as no loss of accuracy was observed with this filter, it could be used as a processing filter.
