Statement of Problem: There is a controversy about the relationship between pulpal and periodontal diseases. The interrelationship between pulp and periodontium could have an important effect on the treatment plan of the tooth.

Purpose: The aim of the present research is to evaluate root canal therapy effects on periodontal healing of teeth with chronic advanced periodontitis.

Materials and Methods: In this randomized controlled clinical trial 32 single rooted teeth which had necrotic pulp or irreversible pulpitis in 7 patients with chronic advanced periodontitis were selected based on specific criteria. Using a split mouth design, teeth were randomly put in two groups of test and control. In the test group root canal therapy ,scaling & root planing were done.In the control group, only scaling & root planing were performed. Clinical parameters including Pocket Depth (PD), Clinical Attachment Level (CAL), mobility, pattern of bone destruction and plaque index (PI) were evaluated in two groups at base line, 1 and 3 months after treatment. Appropriate tests such as paired Wilcoxon and Mann-Whitney were performed.

Results: Statistically significant reductions were found in the test group when comparing baseline and one-month post treatment values for Clinical Attachment level (CAL) but not after 3-months. In the control group the CAL reductions were not statistically significant between baseline and one month post-treatment, but a increase were observed between one month and three months after treatment. There was a statstically significant difference between the test and the control groups. Other parameters didn’t show any significant differences in each group and between two groups.

Conclusion: Since clinical attachment level was the most important parameter we found it can high lighted the role of pathogene with pulpal origin in progression of periodeontal disease and it is concluded that beside periodontal treatment in some advanced periodontal cases pulp therapy maybe an effective procedure for eleminating destructive pathogens of pulp and causing periodontal healing.

Statement of Problem: A few decades have past from using radiographic technology as an accurate paraclinical method and always protective measurements is applicated against ionizing radiation. As dental radiography is a routine procedure in dentistry the importance of protective strategies is clear.
Propose: The aim of this descriptive study is to evaluate the protection principles in centers which have intraoral radiographic devices in Yazd.
Material and Methods: We have considered all three aspects of practitioner, environment and patient protection using questionnaire and visiting those centers.
Results: 33/7% of dental offices ,10 clinics ,3 institution and faculty of dentistry had intraoral radiographic equipments. Stablishment of protection principles for radiographer was favorable. 7.7% of centers had x-ray room with leaded walls, 23.1% had curtain , in 69/2% of centers radiographers stood in correct position and distance while taking radiograph. Regarding to protection of environment, beams leakage control in 23.1% dental offices, 70% of clinics, all institution and faculty of dentistry have done.
Conclusion: Non of the centers used rectangular localizator, thyroid shield, film holder and just some centers used leaded apron in specific circumstances. We have concluded that patient protection constitute less consideration. Generally lack of protective consideration is related to deficient knowledge of operators. Lack of information about protection equipments causes decrease of demanding of these tools and ultimately lack of these equipments in the market.

  Background and Aims : Antibiotics are commonly used for controlling the growth of porphyromons gingivalis (P.g) which is one of the most important etiologic factors in the periodontal diseases. Different side effects of synthetics and chemical drugs such as increasing the drug resistancy in the human pathogens have led to study on the herbal antibacterial effect. The aim of this study was to evaluate the antibacterial effect of cinnamon on the growth of porphyromons gingivalis in chronic periodontitis patients with deep pockets.

  Materials and Methods: In this experimental study, samples were provided from patients having pockets. After culturing the microorganism and diagnosis of P.g by gram staining and biochemical tests, cinnamon in different concentrations (10, 50, 100, 250, 500, 750 and 1500 mg/ml ) with oil solvent were prepared and placed by disks in the cultures medium. Positive controls were amoxicillin, metronidazole, ciprofloxacin, amikacin and gentamycin . Oil was negative control. Then the plates were incubated for 24 hours in 37 0 C and then non-growth halos by disk diffusion method, MIC (Minimum Inhibitory Concentration) and MBC (Minimum Bactericidal Concentration) were determined. Data were analyzed using One-way ANOVA test.

  Results: The results showed that the cinnamon at the concentration of MIC=750 mg/ml had the inhibitory effects of bacteria and at the concentration of MIC=1500 mg/ml had killing effect. However, this antibacterial effect compared with commonly used antibiotics (amoxicillin, metronidazole), was much weaker (P<0.001).

  Conclusion: Cinnamon showed an antimicrobial effect on porphyromonas gingivalis in chronic periodontitis patients with deep pockets.

  Background and Aims: Tooth crowning often leads to changes in periodontal index through changes in emergence profile zone. The purpose of this study was to compare the effect of metal-ceramic with that of
All-Ceramic restorations on the plaque a accumulation.

  Materials and Methods: In this clinical trial, we used 102 teeth covered with metal-ceramic and all-ceramic restorations. Before and after crowning, plaque index (PI) and gingival indexes (MGl) were measured. Data were analyzed using covariance (ANCOVA) test.

  Results: Measured PI and MGI (Mean±SD) in PFM Group prior to crowning were (1.96±0.38) and (1.45±0.48), respectively. In metal-ceramic restorations group, six months after crowning, measured PI and MGI (Mean±SD) were (1.22±0.49) and (1.82±0.61), respectively. Measured PI and MGI (Mean±SD) in All-Ceramic Group prior to crowning were (1.22±0.52) and (1.25±0.29), respectively. In All-Ceramic, six months after crowning, measured PI and MGI (Mean±SD) were (0.88±0.51) and (1.43±0.50), respectively. ANOVA test showed statistical significance difference between metal-ceramic and All-Ceramic Groups in Indexes (P<0.001).

  Conclusion: Metal-ceramic and All-Ceramic crowns were associated with inflammatory changes in gingival. Metal-ceramic restorations were associated with higher inflammatory indexes compared with All-Ceramic crowns.

Background and Aims: One of the most effective methods in reducing the prevalence of caries is oral health education. The aim of this study was to evaluate of two educational interventions regarding prevention of early childhood caries on self-reported practice of parents of 2-5-year-old children receiving dental treatment under general anesthesia.

Materials and Methods: In this interventional study, the effects of two different educational interventions
(pamphlet and pamphlet along with reminder) on self-reported practice of parents of 2-5-years-old children receiving dental treatment under general anesthesia was assessed. Thirty seven couples of children and mothers in two groups were randomly selected. Before and three months after interventions, a standard questionnaire regarding self-reported practice of mothers on prevention of early childhood caries was completed by respondents. Moreover, oral examination including Simplified oral hygiene index (S-OHI), dmft, and white spot lesions were rerecorded at the beginning and three months after interventions. At this time in one of the groups reminder phone calls were made every month. Finally, the answers were scored and data were statistically analyzed to be compared in pre- and post-test.

Results: Comparing each of the groups before and after interventions showed that in both groups there were significant differences in mothers’ perception of perceived ability to make child brush his teeth twice a day (P=0.001), and child’s tooth brushing frequency more than once a day (P=0.03). S-OHI had no significant difference after the intervention between two groups. But each group had a significant decrease three months after intervention (P=0.003). Also the mean number of white spots showed a significant decrease before and after intervention in each groups. Regarding mothers’ self-reported practice no significant difference was observed between two groups (P>0.05).

Conclusion: Using pamphlets along with or without reminder as educational measures had similar enhancing effects on the mothers’ self-reported practice on oral health of children within three months.

Background and Aims: Dental diagnosis may be affected by the occurrence of the errors in the intra-oral radiographic images and the patients’ treatment plan can be problematic in these cases. The repetition of these radiographs increases the risks of radiation exposure for the patients in turn. The present study assessed the incidences of common periapical radiographic errors taken by dental students in oral and maxillofacial radiology department of Mashhad dental school in 2017.
Materials and Methods: In this cross-sectional descriptive study, 1470 periapical radiographs prepared by student during a semester of 2017 were collected and evaluated. Radiographic observations were done and the incidence of conventional radiographic errors were determined. Finally, the frequency and percentage of radiographic errors were determined based on the type of radiography sex, the age of the patient, and the history of radiography. Then, results were analyzed using the Chi-Square test and SPSS19 (P=0.05).
Results: Film placement (27.2%), cone-cut (27.2%), elongation (13.2%) and horizontal angle (10.9%) were reported as the most common radiographic errors. The repetition rate of the radiographs was 2.9%; among them, the highest errors were Cone-cut errors in the upper jaw
Conclusion: Based on the results of this study, the most radiographic errors included film position and Cone-cut errors and these two errors were the most frequent cause of repetitive radiographies that required the provision of specific training for the prevention of these errors.

Background and Aims: All metal components of orthodontic appliances are somewhat corroded in the oral environment due to some changes in chemical, mechanical, thermal, microbiological and enzymatic factors which facilitates ion release. Ionic release can result in a discoloration of the surrounding soft tissue or allergic reactions in sensitive patients or even local pain in the area. In general, ions can cause toxic and biological side effects if their values reach the threshold, so the release of ions from the metal components of orthodontic appliances is important to us. The aim of this review article to determine the rate of orthodontic appliances ion release in different solutions.
Materials and Methods: A review of the literature was carried out in Pubmed, Google Scholare and Web of science database using selected key words (Saliva/ Titanium/Normal Saline/ Ion release Orthodontic appliance/Mouth wash/ Nickel/ Chromium). These searches were limited to the articles published from 2005 to 2018. According to the inclusion and exclusion criteria, 25 articles were obtained.
Results: Because of conflicts in the reported results, it was necessary to synchronize the measurement methods and also to use artificial saliva medium with normal pH as a control to achieve better systematic comparison.
Conclusion: There was significant differences in the ion release between mouthwashes. In all studies, the effect of pH and acidity has been shown to increase the release of these ions. In addition, stainless steel (SS) instruments had the least biocompatibility among all types of alloys evaluated.

Background and Aims: Supporting the preventive approach is important in training future dentists. The purpose of the present study was to evaluate the knowledge, attitude and practice of senior dental students regarding non-invasive management of dental caries.
Materials and Methods: A cross-sectional study was conducted in 2019 using total sampling method and a valid and reliable questionnaire. Knowledge, attitude and self-reported practice of senior dental students regarding caries risk assessment (CRA) and management of lesions in two paper patients were assessed. The data analysis was performed using SPSS20 and the descriptive and analytical statistics were reported.
Results: In overall, 86 students (response rate=91%) were responded. In the knowledge section, caries history in the previous year, having frequent fermentable carbohydrate, xerostomia, and low socio-economic status were considered by more than half of students as factor for caries risk assessment. More than 90% of students had a positive attitude towards CRA in children. Nearly 50% of students tend to restore enamel lesions in proximal and occlusal surfaces in high-risk scenarios. There was significant association between the OHI instruction and debris index improvement (P=0.04) in the integrated comprehensive care clinic (TUMS). The linear regression analysis showed that there was no significant association between the demographic characteristics, place of education, previous course on the level of knowledge and attitude.
Conclusion: Senior dental students despite their general knowledge and positive attitude toward caries risk assessment, tended to aggressively manage the incipient lesions in the enamel and DEJ. Delivering prevention as integrated in the comprehensive care unit in order to improve oral hygiene status of patients is recommended.
