Background: The objective of the present study is to evaluate the impact of oral health practice and knowledge level of caregivers on periodontal status of adults special needs in Aseer Region, Saudi Arabia. Methodology: A cross-sectional study was conducted on 180 caregivers and 180 adults with special needs divided into three equal groups (n = 60 + 60 + 60) based on type of disabilities: Visual impairment group (I); moderate mental retardation group (II); and physical impairment group (III). Questionnaire forms were used to assess the oral health practice and knowledge level of caregivers. The clinical examination of special needs adults was done to assess the effect of oral health practice and knowledge level of caregivers on periodontal status of adults special needs. All data were collected and analyzed by the SPSS statistical software and (ANOVA) to assess the variations in the mean and standard deviation (±SD) of clinical findings. Results: Acceptable periodontal, oral health knowledge, awareness and oral health practice were detected among caregivers, particularly, group (II) more than group (III) and group (I). But there were no significant differences in periodontal clinical parameter scores in the comparison between the study groups. Conclusion: It is concluded that the level of oral health practice and knowledge of caregivers included within the current study, were not effective in keeping periodontal health of special needs adults.

Background: Periodontal disease is a bacterial infection that causes bone resorption of bone supporting teeth and leads to change in the normal architecture of the alveolar process. There are instances where the technique sensitive nature of restorative procedures or the faulty restorative margins may inadvertently lead to conditions which could bring about periodontal disease/ destruction. Therefore, this study was designed to determine the impact of dental restorations type on marginal bone among some patients being treated for chronic periodontitis. Material and Methods: Three hundred patients from the periodontics clinics in college of dentistry, King Khalid university were participated in our study. A total of 292 patients completed the study, 152 males and 140 female. They were divided according to dental reconstructions into three groups: Group I was without dental reconstructions (control group), group II patients received amalgam class II fillings and group III received fixed bridge denture. Plaque index (PLI) gingival index (GI), clinical attachment loss (CAL) and marginal bone loss (MBL) were recorded. All data were collected and were analyzed by ANOVA test. Results: In the present study, the restored teeth revealed significantly higher mean values for PLI, GI, CAL and MBL than the non-restored teeth (p-value < 0.05). Conclusion: Although the limitations of the present study, the patients in group II had the highest clinical attachment loss and value of marginal bone loss which can explain the more extension of amalgam fillings into subgingival direction, leading to increased plaque accumulation and increased periodontal destruction.

Background: Periodontitis is the predominant disease in the oral cavity and there are alterations in the periodontal tissues associated with the aging and gender of the patient. Objective: The present study was designed to assess the impact of age and gender of the patient on severity and types of periodontal diseases among patients from two regions in Saudi Arabia. Materials and Methods: The current study was done on 600 Saudi patients from Aseer and Tabuk regions in Saudi Arabia (50% males and 50% females) and divided into three equal groups (n = 200) according to the patients age: children and young patients (1 -24 years old), adults patients (25 -64 years old) and seniors patients (more than 65 years old). Plaque index (PLI), gingival index (GI), periodontal pocket depth (PPD) and clinical attachment loss (CAL) were recorded from all participants. The data were collected and analyzed with SPSS to determine the mean and standard deviation (±SD) and the values of significance (P ≤ 0.005). Results: The results of the present study revealed that 340 patients (56.7%) were affected with gingivitis dental biofilm induced and 260 patients were affected by periodontitis. Gingivitis dental biofilm-induced is especially detected in children and young patients (33.3%), adult patients (16.7%) and seniors patients (6.7%) whereas periodontitis cases were seen among the adult and seniors patients (16.7%) and (26.6%) respectively. Furthermore, the present study displayed the higher severity and prevalence of gingivitis dental biofilm-induced and periodontitis among females more than males in group II and group III maybe due to hormonal changes. The present study saw that there are statistically significant differences in clinical findings in the comparison between groups of this study (P ≤ 0.005). Conclusion: We conclude that there is a relation between severity and types How to cite this paper:

Background: The formation of kidney stones is considered a complicated process. Consequently, there are many questions about the link between kidney stones formation and level of salivary uric acid and calculus formation on the teeth surfaces. Objectives: To evaluate the correlation between the level of salivary uric acid and kidney stones formation and their influence on dental calculus and periodontal status among Saudi patients aged 25-70 years. Materials and Methods: 120 Saudi male patients were examined (60 of Kidney stones patients and 60 patients of non-kidney stones patients) for clinical evaluation of plaque index (PLI), gingival index (GI), calculus index of oral hygiene (CI) and clinical attachment loss (CAL). Moreover, lab assessment of uric acid level in the collected salivary samples was done. The findings were analyzed using of ANOVA test and Tukey's test. Results: There were statistically significant differences in clinical parameters among kidney stones patients and non-kidney stones patients (p < 0.05), but these differences were highly statistically significant in the correlation between calculus index (CI), plaque index (PLI) and gingival index (GI) among kidney stone patients in group II, moreover, PLI and clinical attachment loss (CAL) among kidney stone patients in group III (p < 0.001). The statistical analyses revealed statistically significant differences in the level of salivary uric acid (mg/dl) in the comparison between kidney stones patients and non-kidney stones patients in group I and group III, whereas there were highly statistically significant in the comparison between kidney stones patients and non-kidney stones patients in group III. Conclusion: At the end of this study, we

Background: The correlation between oral health and dental restoration is fundamental. For the gingival and periodontal tissues to stay healthy, dental restoration should be in regularity with the surrounding tissues. This study aims to assess the oral health status and histopathological gingival response to three different restorative materials among Saudi patients. Methods: The study groups consist of 240 patients (50% males and 50% females), aged 18-45, with inclusion and exclusion criteria in the study. Participants are divided into three equal groups: those with composite resin restorations, those with amalgam restorations and those with glass ionomer restorations. Biopsies were taken from adjacent gingival tissues. Clinical parameters were determined by: plaque index (PLI), gingival index (GI) and clinical attachment loss (CAL). All data were collected and evaluated by through statistical analysis. Results: The clinical findings of the current study revealed that amalgam restorations produce a higher means of PLI, GI and CAL compared with composite resin restorations and glass ionomer restorations, but not insignificant levels, except CAL (p = 0.004*). As for histopathological findings, there were significant differences in gingival tissue response to amalgam restorations, composite resin restorations and glass ionomer cement fillings, where there were statistically significant differences in numbers of chronic inflammatory cells (p < 0.001). Conclusion: At the end of the present study, we concluded that the amalgam restorations are less biocompatible compared to composite resin restorations and glass ionomer restorations.

Objective: To assess the actual practical attitude and knowledge of dental implants among senior dental students and general dentists graduated from some Saudi and Non-Saudi dental schools. Methods: A total of 300 senior dental students and general dentists participated in the study. Hard copies of the self-designed, multiple-choice questionnaires were distributed to all participants. The questionnaire consisted of 31 questions in five parts. Data were collected and analyzed using Chi-square test and t-test, where p < 0.05 was calculated to be statistically significant and p < 0.001 to be statistically highly significant. Results: There is a statistically significant relationship between the participants' answers, and their dental schools. Participants' general knowledge, training, and teaching of dental implants, as well as information about restorations retained for the dental implants, were higher among participants from Saudi dental schools than participants from non-Saudi dental schools, while the information about dental implants was higher among participants from non-Saudi dental schools than participants from Saudi dental schools. Conclusion: We conclude that the actual practical attitude and knowledge of dental implants among participants in the current study was insufficient. Therefore, dental implant education in the undergraduate curricula of dental schools surveyed should be updated to include teaching, laboratory training, and preclinical and clinical training.
