Using bone grafts has been described in the literature for multiple decades and has been applied within the different medical fields. Furthermore, in the field of dentistry, evidence shows that these approaches have been widely used for different purposes, including the management of craniofacial defects and dental implantology. However, it should be noted that many disadvantages have been reported for the different tissue sources of bone grafting in dental implants despite the wide acceptance of the outcomes and favorable prognosis with these materials. Therefore, many efforts were conducted to innovate further approaches with reduced disadvantages and favorable outcomes. Our present study discusses the types and tissue sources of bone grafts in the settings of dental implants. This can provide dentists with better information and enhanced knowledge levels about the tissue sources of dental implants, which should help them decide the most appropriate source with the least adverse events. Different tissue sources were reported in the literature, including materials that are no longer used for their disadvantages and associated complications. Among the proposed materials, biomimetics has been reported with favorable outcomes and reduced adverse events, and using combinations of these materials can furtherly enhance the prognosis. Further research is needed to innovate additional modalities that can overcome the currently reported limitations.

When compared to adults, older persons have a higher prevalence and incidence of periodontal diseases. The prevalence of periodontitis is substantially greater in the geriatrics group, which is 75 years old on average, compared to those who are 60 years old on average. Periodontitis can lead to tooth loss if natural periodontal therapies are not used. Periodontitis is the sixth most frequent incurable illness in the world, characterized by bacterial-induced and host-mediated deterioration of both soft and hard structures around the teeth. A severe type of periodontitis affects around 10% of the world's population. Periodontitis is more frequent in adults because of its chronic and debilitating nature, with around 66% of the 65-year-old age group in the United States afflicted by chronic periodontitis. A critical component of a successful disease prevention and health promotion trajectory is having up-to-date information on demographics, clinical symptoms, and illness burden on individuals, particularly in underrepresented regions where preventive programs are targeted and executed. As a result, the purpose of this paper is to evaluate the existing research on the prevalence, incidence, and consequences of periodontal diseases in the older population.

Dental neglect is a common condition among children and it can be associated with several adverse events as dental caries, dental pain and inflammation, infections, trauma, bleeding and other complications that might result from inadequate administration of adequate prevention and treatment modalities. However, many children and parents are not adequately aware of these events and the potential diseases that might be associated secondary to them. Dental neglect is a common condition that might affect children of different age groups and might also extend to adult groups and is affected by the demographics and socioeconomic characteristics of the affected populations. Furthermore, the etiology of dental neglect is variable and parenteral, child and clinical care should all be integrated to achieve better oral health. Many adverse events have been reported as dental caries and other periodontal diseases that might have a significant impact on the affected teeth and the succeeding permanent ones, which might impact the quality of life in the affected children. Accordingly, dental neglect should be given full care to enhance the outcomes of oral health in children.

As a result of the increasing needs among the public to enhance esthetics, many approaches have been made and the results included different approaches as non-metallic tooth-colored restorations, including the direct and indirect resin composites. In addition, another approach is the ceramic onlays or inlays. In this study, we aim to formulate strong evidence regarding the differences between direct and indirect resin composite the clinical outcomes, and related effects on esthetic restorations, based on evidence obtained from the current and previous studies in the literature. Many differences were discussed within the study manuscript between the direct and indirect resin groups. Furthermore, evidence shows that esthetic outcomes are in favor of the latter. We also discussed the color stability outcomes for the two groups and evidence in this area was controversial. Finally, many studies have reported that the clinical efficacy of the indirect resin composites is superior to the direct ones, while many others reported that they are similar, and only a few reported that direct resin composites are superior. Accordingly, further studies are encouraged to unify these contradicting results.
