Aims and Objectives:The parent's oral health knowledge has a great influence on their children, so the aim of the study was to estimate the parental knowledge about oral health care and its influence in maintaining the diet and hygiene practices on their children and also to access how the demographic variables will influence them in taking their child to dental visits.Materials and Methods:The self-administered pretested questionnaire was distributed among Saudi parents whose children are in the age group of 2–6 years vising primary health care centers (PHCCs) in Riyadh city. The PHCCs were divided into five zones (Central, East, West, South, and North). 240–250 samples were randomly selected from each zone to reach the prescribed sample size of 1200. The survey will be composed of self-administered pretested questionnaires seeking for age, gender, educational level, and their financial status followed by 26 questions related to parent knowledge about oral health (14), dietary (5), and hygiene (7) practices what they implement on their child. The data collected were analyzed using SPSS software SPSS 25.0 (SPSS, Inc., Chicago, IL, USA).Results:Demographic information showed that the average age of the parents who participated in the study is 32.2 years. The mothers were 942 (75.7%) and fathers were 303 (24.3%) among the participants. The mean knowledge score among the mothers (34.85) is slightly greater than fathers (34.76). Similar results with dietary and hygiene practices were not statistically significant (>0.05). The parents having more than one child have better knowledge, of which the parents with more than three children have better scores, which is statistically significant. 69.3% of the parents prefer taking to a dentist only when they have a problem. Moreover, these findings found to be statistically significant (P < 0.05).Conclusion:Parents should get access to oral health knowledge to put in practice on their children so as to influence them in gaining better oral health.

Aim:The aim of this study was to detect and describe the patterns of implant prosthetic treatment modalities placed in partially and fully edentulous Saudi patients restored with dental implants in Saudi Arabia, and to detect the status of the health insurance covering dental implants in Saudi Arabia. Materials and Methods: 520 Saudi patients aged ≥18 years residing in Saudi Arabia and treated with at least one dental implant done in dental health premises in Saudi Arabia were randomly included in the study. Clinical and radiographic examination were used to detect implant prostheses types (single-tooth implant, implant-supported long or short span conventional fixed bridge, implant overdenture). The health insurance covering dental implants was detected too. The data obtained including age, gender, systemic disease, and tobacco smoking were documented in a patient examination form then statistically analyzed using Chi-Square Test and U-Test. Results: The most frequently tooth type replaced by dental implants was the molars (45.5%), followed by premolars (40%), incisors (7.7%), and canines (6.8%); mandibular first molars were the most common tooth type replaced by implants. Single-tooth implant was the most common prosthetic treatment modality (85.2%), followed by implant-supported short span conventional fixed bridge (9.8%), implant overdenture (2.8%), and implant-supported long span conventional fixed bridge (2.2%). The majority of implant overdenture prostheses were seen in the age group ≥ 60 years. Implant-supported long span fixed bridge prostheses were more in patients aged ≥ 50 years than in patients aged < 50 years, while single-tooth implant prostheses were more in patients aged < 50 years than in patients aged ≥ 50 years. Of all teeth types replaced by dental implants, molars were the most common type seen in implant-supported long span fixed bridges and in single-tooth implants, whereas canines were the most common type seen in overdentures. There was an insignificant difference in the median number of dental implants between males and females. Conclusion: Single-tooth implant is major. Health insurance policy doesn’t cover dental implants in Saudi Arabia. Keywords: Implant, Modalities, Prostheses/Prosthetic, Type
