Background and Aims: Although dental implants have become a successful and predictable ong-term treatment for patients, not all implant treatments are necessarily successful and pre-implant diseases are spreading. The aim of this study was to determine the prevalence of peri-implantitis in patients one year after prosthetic loading in Khorramabad in 2021.
Materials and Methods: In this cross-sectional study, 53 patients who had implants and undergone prosthetic loading for one year were studied. In each of the 53 patients, the probing depth (PD) and bleeding during probing (BOP) around the implant and the characteristics of the surrounding soft tissue, including gingival redness and tissue sensitivity were evaluated and recorded. To assess the bone level or possible bone resorption, a P.A. graph was taken from the patient using a parallel technique. Information such as demographic characteristics and specialized information about the disease were collected through a checklist. Data were collected using SPSS22 software. Frequency tables and chi-square and t-tests were used to analyze the data.
Results: The mean age of patients participating in the present study was 46.5±10.63 years. The number of women was 33 (62.3%). The prevalence of peri-implantitis was 17% at the patient level and 9.3% at the implant unit level. There was a significant relationship between the age (P<0.03) and systemic disease (P<0.03) with the prevalence of peri-implantitis. However, there was no statistically significant relationship between the prevalence of peri-implantitis and other demographic variables (P<0.05).
Conclusion: The results of the present study showed that the prevalence of peri-implantitis was higher in people with a higher mean age. In addition, systemic diseases are a protective factor for peri-implantitis.

Background and Aims: Oral health is a necessity and part of general health and its importance in childhood is more than ever. The aim of this study was to investigate the knowledge, attitude, and practice of parents in Delfan city-Iran about oral health of their 6-12-year-old children in 2021.
Materials and Methods: The present study was a descriptive-analytical study that was performed on 365 parents of 6-12-year-old children in Delfan city. Convenience sampling was used. The questionnaires included four sections: demographic information, knowledge, attitude and practice about oral health. Data were entered in SPSS23. Independent t-test, analysis of variance and Pearson correlation were used to analyze the data. Significance level was considered 0.05.
Results: The mean age of the subjects was 36.5±7.1. 201 of parents were mothers. Parents' knowledge and attitude were good and their performance was fair. There was a statistically significant relationship between all three variables of knowledge, attitude, and practice (P<0.00). Also, there was a statistically significant relationship between the knowledge and education (P<0.00), mother job (P<0.04), father job (P<0.00), and economic status (P<0.00). There was a statistically significant relationship between the attitude with education (P<0.00), mother job (P<0.04), father job (P<0.01), and economic status (P<0.01), There was a statistically significant relationship between practice and education (P<0.00), mother job (P<0.01), father job (P<0.00), and economic status (P<0.00) of parents.
Conclusion: The results of this study showed that there was a significant relationship between the knowledge, attitude, and practice with education level, job and economic status. Therefore, oral health education for parents with low educational and economic level should be highly considered.

Background and Aims: The white color of teeth is one of the most essential factors in smile esthetics. Therefore, various whitening agents such as bleaching mouthwashes have been produced in response to the people’s high demand for having whiter teeth. The present study evaluated the efficacy of three whitening mouthwash products on tooth enamel whiteness.
Materials and Methods: In the present in vitro study, 32 bovine incisors were assigned to four groups in terms of the mouthwash used (n=8): control (C); Xenon Smart White (ZSW), containing pyrophosphate and triphosphate; Signal White Now (SWN), containing Blue Covarine; and Pasta Del Capitano whitening mouthrinse (PCW), containing Plasdone. Colorimetry was carried out using a spectrophotometer at the baseline and 2, 4, 8, and 12 weeks after treatment with mouthwashes. Data were analyzed using CIELab parameters with ANOVA, RM two-way ANOVA, and post hoc Tukey tests (α=0.05).
Results: The results showed that the whiteness created by the SWN mouthwash was clinically visible (ΔE>3.3). However, the functions of all the mouthwashes were statistically similar with no significant differences from the control group (P>0.05).
Conclusion: Although, Blue Covarine-containing mouthwash was somewhat effective in whitening of tooth enamel, none of the mouthwashes had significant efficacy compared to distilled water.
