However, quality control of data is one of the most important steps in research projects. Lack of sufficient attention to quality control of data might have a detrimental effect on the results of research studies. Therefore, directing the attention of researchers to quality control of data is considered a step necessary to promote the quality of research studies and reports. We have made an attempt to define the processes of cleansing and preparing data and determine its position in research protocols. An algorithm was presented for cleansing and preparing data. Then, the most important potential errors in data were introduced by giving some examples, and their effects on the results of studies were demonstrated. We made attempts to introduce the most important reasons behind errors of different natures; the techniques used to identify them and the techniques used to prevent or rectify them. Subsequently, the procedures used to prepare the data were dealt with. In this section, techniques were introduced which are used to manage the relationships established between the premises of statistical models before carrying out analyses. Considering the widespread use of statistical models with the premise of normality, such premises were focused on. Techniques used to identify lack of normal distribution of data and methods used to manage them were presented. Cleansing and preparation of data can have a significant effect on promotion of quality and accuracy of the results of research studies. It is incumbent on researchers to recognize techniques used to identify, reasons for occurrence, methods to prevent or rectify different kinds of errors in data, learn appropriate techniques in this context and mention them in study reports.}, keywords = {Cleaning,Preparation,statistics,Data,Quality Control}, url = {https://johoe.kmu.ac.ir/article_84854.html}, eprint = {https://johoe.kmu.ac.ir/article_84854_405f2f9e04e387cc9fd48427b8dc04dc.pdf} } @article { author = {Kakoei, Shahla and Navabi, Nader and Aghaabbasi, Shiva and Hashemipour, Maryam Alsadat}, title = {Oral health related quality of life in patients with diabetes mellitus type 2 in the year 2012}, journal = {Journal of Oral Health and Oral Epidemiology}, volume = {5}, number = {4}, pages = {186-191}, year = {2016}, publisher = {Kerman University of Medical Sciences}, issn = {2322-1372}, eissn = {2322-1372}, doi = {}, abstract = {BACKGROUND AND AIM: The aim of this study was investigation of oral and dental side effects of diabetes mellitus (DM) on oral health-related quality of life (OHQoL) in patients with DM type 2.METHODS: In this descriptive, analytic study 121 patients were participated by consecutive method based on the type of diabetes and the age. After the subjects received adequate explanations about the necessity of carrying out such a study, a questionnaire was handed into each patient who gave their consent to take part in the study. Oral lesions consisted of ulcers, erythema, leukoplakia, erythroplakia, candidiasis, angular cheilitis, median rhomboid glossitis, and denture stomatitis based on oral examination. The OHQoL were surveyed by oral health impact profile (OHIP-14) questionnaire. Data were analyzed by Pearson’s correlation test, T-test, and χ2 by SPSS software.RESULTS: A total of 121 patients with diabetes were evaluated in this study [31 males (25.6%) and 90 females (74.4%)]. In this study, there was no significant correlation between OHQoL and decayed, missing, and filled teeth, periodontal disease index. OHQoL was associated with higher ages and higher levels of blood sugar (P = 0.002, P = 0.016). The average of OHIP score significantly was increased by xerostomia experience (P = 0.010).CONCLUSION: In this survey, the influence of oral manifestation on OHQoL was low. Xerostomia was the most important symptom in diabetic patients that causes decreasing OHQoL.

This study was conducted to assess the knowledge, attitudes and practice of general dental practitioners and pediatricians in relation to techniques used to prevent dental caries, including use of fissure sealants and fluoride therapy, in the south-east of Iran.METHODS: A cross-sectional survey was conducted between 399 general practitioners and pediatricians in the south-east of Iran. Data collected through a self-administered questionnaire consisted of demographic characteristics, questions that evaluating, knowledge, attitude and practice level regarding preventive methods of dental caries. Then, scores were given to each question and sum of the scores was categorized to weak, moderate and good. These scores were evaluated as follows: < 50%: weak, 50-75%: moderate, and > 75%: good.

Then, the study design of each article was determined followed by assigning LOE according to Oxford scale whereby systematic review and randomized clinical trial possess highest-LOE and expert opinion has lowest-LOE. Descriptive statistic indices were applied to summarize the results.RESULTS: Of all the articles, 34.6% were in-vitro, 24.3% were cross-sectional and 8% were randomized controlled trials (RCT).

The mean length and thickness of the SP, morphology, and pattern of calcification between the two sides in each group and between ES and asymptomatic groups were compared. The t-test was used for comparison. Fisher exact and chi-square tests were used to determine the relationship between different types of calcification pattern and morphology. The level of significance was considered at P < 0.050.RESULTS: The SP was thicker in the ES group than the asymptomatic group. However, the styloid length showed no significant difference among the ES and asymptomatic groups. The most common pattern of calcification in both groups was partially calcified with no significant difference between the two study groups.

In this study, we assessed the effect of two training methods on short-term oral health outcomes among children with impaired hearing.METHODS: In this experimental study, 80 hearing impairment (HI) student aged 7-19 years old were randomized into two groups, one group watched a guided training video and the other group was educated by a dental model. The training sessions were weekly and continued for 1 month. A trained dentist examined all participants using O’Leary plaque index (PI) at baseline, 1-month, and 3-month visits.RESULTS: At baseline, the difference between the mean O’Leary PI in the video training and dental model training groups was not significant (34.3% vs. 35.6%). In the video training group, sharp decrease was seen at the 1-month visit (reinforcement periods), i.e., 18.7% (P = 0.001), followed by a slight increase at the 3-month visit (non-reinforcement periods), i.e., 19.1% (P = 0.100), respectively. On the other hand, in the dental model, a decreasing trend was seen 24.7% at 1-month (reinforcement periods) and 19.9% (P = 0.001) at 3-month visits (non-reinforcement periods).
