    Introduction The increasing awareness of the connection between oral health and systemic health emphasizes the urgency of proper preventive oral care. Identifying deficiencies is crucial for improving preventive oral health behaviors, especially given the rising life expectancy. Encouraging adults to have sufficient knowledge and attitudes can enable the transfer of skills and knowledge to younger generations. Aim and Objectives: To determine the preventive oral health knowledge, attitudes, and practices of patients at selected private dental practices in Pretoria. Design Descriptive cross-sectional study. Methods: Six selected private dental practices located in the North, South, West and East of Pretoria. A self-administered, modified, validated online questionnaire was used to obtain the data. Results: Over half of the participants (55%) knew about dental caries, and 65% were informed of its causes. The majority linked gingivitis with poor hygiene (77%), but 57% lacked knowledge about the role diet plays in oral health. A significant portion (89%) received oral hygiene instructions, mainly from dentists (64%). Most participants brushed twice daily (74.5%). About 40% visited the dentist only for concerns, while 60% went for check-ups and cleaning. Positive attitudes were prevalent. Conclusion: Females, individuals with higher education, and those with medical aid membership displayed superior oral health practices and knowledge compared to others.

    Histologic healing following tooth extraction with socket grafting using demineralised freeze-dried bone allograft (DFDBA), compared to undisturbed normal healing in humans: a randomised controlled clinical trial

    Aim: With dental implant treatment having evolved into a very regularly applied treatment modality, post-extraction grafting of extraction sockets with DFDBA in an effort to anticipate and pre-empt post-extraction bone loss has become common practice – clinically known as ridge preservation procedures. The aim of this study was however to histologically determine the quality of bone available for implant placement using DFDBA as grafting material in combination with a resorbable collagen membrane, compared to bone in extraction sockets that were left to heal naturally. Method: Twenty sites were identified from eight patients requiring replacement of two or more extracted teeth by means of dental implant supported structures, on contralateral sides of the same jaw. They received DFDBA grafting of the socket on one side and no grafting on the contralateral side at the time of extraction. When implants were placed 16 – 20 weeks later, core samples of bone from these sites were first harvested by means of a trephine drill and those samples were processed and examined histologically to determine which of these sites displayed better quality of bone. Results: One patient’s samples could not be utilised. Comparing the samples of the remaining nine non-grafted to nine grafted extraction sites, the difference in the calculated percentages of trabecular bone and collagen as well as the numbers of osteocytes, inflammatory cells and blood vessels were statistically insignificant. Conclusion: The results of the study indicate that statistically there are no significant histological differences between DFDBA-grafted and non-grafted sockets.
