This study aimed to compare implant stability, bone loss, and bone density using the mineralized plasmatic matrix (MPM) and conventional bone grafting methods. Patients were recruited in a stratified sample and each received 2 implants one at each side of their upper jaws. MPM was randomly placed in the surgical site around one implant on one side while a conventional graft, was placed on the other side in a cross-over design clinical trial. A total of 84 implants were placed in 42 patients. A total of 42 implants utilized conventional grafts (GM1) and a total of 42 implants utilized mineralized plasmatic matrix (GM2). Mean Perio test measurements for implants in the group (GM1) were lower than that for implants in the group (GM2) (1.21±3.0 versus 3.57±2.9). Mean radiographic density at grafted sites with GM2 was: 665.2±236.5 whereas for GM1 it was: 577.8±201.2. Implant stability with MPM in males was significantly higher than females (P<0.001). Bone graft loss with MPM in males was significantly less than females (P=0.001). There were no differences between older and younger patients regarding implant stability, bone loss, and bone density (P>0.05). It is concluded that utilizing MPM in implants may be associated with better implant treatment outcomes of implant stability, bone graft loss, and density when compared to conventional bone grafts. Gender but not age differences may be noticed when comparing implant stability and bone graft loss in implants utilizing MPM.

Background and Aim: Dental caries is a multifactorial, widespread chronic infection of the enamel, or dentin caused by plaque. Susceptible tooth surfaces, saliva, oral micro flora, and dietary carbohydrates are the main factors involved in the development of dental caries. Treatment and prevention management of caries among the population is measured in terms of prevalence and severity of anterior teeth caries. The present study's aim was to determine the prevalence of anterior teeth caries among adults. Methodology: This epidemiological study was conducted on 1276 patients reporting for treatment at the College of Dentistry, Jouf University, Saudi Arabia from January 2021 to July 2021. Detection of carries was carried out as per World Health Organization (WHO). Based on demographic details such as age, gender, occupation, and diet, the prevalence of carious anterior teeth was assessed. All the data was coded and analyzed using SPSS version 24. Results: Out of 1276 patients, male and female patients were 814 (63.8%) and 462 (36.2%) respectively. The incidence of carious anterior teeth was 263 (32.2%) in males whereas 149 (32.3%) in female patients. The overall incidence of carious anterior teeth was 32.25%being prevalent in male patients with an age range from 21 years to 30 years. A significant association was found among carious anterior teeth, age (p<0.05), diet (p<0.05), location (p<0.05), teeth malalignment (p<0.05), and oral hygiene (p<0.05). However, anterior decay had no significant association with gender (p=0.673) and occupation (p=.167). Maxillary central incisors were the commonly affected teeth in most cases. Conclusion: Our study found that the prevalence of carious anterior teeth was 32.25% and Maxillary central incisors were the commonly affected teeth in most cases. A significant association was found among carious anterior teeth, age, location, oral hygiene, diet, and teeth malalignment. But no significant association among carious anterior teeth, occupation, and gender. Keywords: Anterior caries, prevalence, dental caries
