Knowledge and awareness of oral health issues are essential for prevention of dental and other associated systemic diseases. This study explores among visually impaired subjects living in Jazan region, with the respect to frequency and quality of use and the effect of type of blindness on the distribution of oral health related knowledge and behavior. Supervisors taking care of visually impaired subjects of different degrees were informed about the aim of the study. A total of 92 questionnaires were distributed randomly to be completed by the consent participants from each age group, gender and categories of blind situation. First, a consent letter was carefully read to the participants by the interviewer and data collected, and then processed and analyzed by means of the Statistical Package for Social Sciences. In total, 71.5% total blinds and 63.6% partial blinds scored high in the knowledge of caries. The corresponding rates regarding the knowledge of gingivitis were 61.2 and 41.4%, respectively. The scores of knowledge of oral infection in relation to systemic disease were 31.1% total blinds and 29.3% partial blinds. Tooth brushing ≤2 times a day was confirmed by 44.2% total blinds and 42.4% partial blinds, respectively. Awareness of oral health issues is high among the study subjects, but specific misconceptions exist. There is equality in knowledge and practice of oral hygiene among the types of blind subjects.

Aims: To assess the awareness, knowledge, and information sources regarding dental implants as an option of treatment to replace missing teeth among patients in Jazan Province, Saudi Arabia. Materials and methods: The current study consisted of 14 questions used to assess the patients' awareness, expectations and level of knowledge of dental implants. Three categories of questions were used, with the first one related to the patients' knowledge and options for replacement of missing teeth, the second about dental implants and their providers, and the third on the techniques, materials, care, and durability of dental implants. The collected data was analyzed using Chi-square tests, and P values less than 0.005 were considered significant. Results: A total of 380 subjects were divided into two groups, medical (40.3%) or non-medical (59.7%) related. We found that 85% and 71.0% of the medical and non-medical subjects, respectively know the importance of replacement of missing teeth, while 50% had known the different types of dental implants with no significance (P< .001) between the two groups. Dentists were the sources of the information (43.3% and 34.8% for the medical and non-medical groups respectively). Around 50% of the medical subjects thought that dental implants came with a screw compared with 36.6% of non-medical subjects with value of P .025. In total, 60%-70% of respondents from both groups answered that dental implants should be provided by specialists only. Around 29% of all patients cited "lifetime" as the survival period of implants. Also, 52%-77% of the respondents related the implant site to the "the jaw bone," with significant difference of P .000. Conclusions: The awareness and knowledge of the subjects were acceptable with higher percentage among respondents in the medical group. Dentists followed by friends were the main sources of information for dental implants. Dental implants are considered as the best choice for replacement of missing teeth with excellent durability and need of much more special care than natural teeth.
