Efectos del tratamiento periodontal sobre el perfil ateroscler贸tico
Treball Final de Grau d'Odontologia, Facultat d'Odontologia, Universitat de Barcelona, Any: 2016, Director: Carlos Mendieta FiterLa enfermedad cardiovascular ateroscler贸tica (ECVA), de origen multifactorial y principal causa de morbimortalidad en los pa铆ses desarrollados, se ha visto asociada en los 煤ltimos a帽os a la enfermedad periodontal; patolog铆a inflamatoria cr贸nica con la que comparte algunos factores de riesgo. Los pacientes periodontales tienen mayor riesgo de padecer sucesos cardiovasculares futuros, existen distintos mecanismos biol贸gicos capaces de explicar la posible relaci贸n causal entre ambas. Sin embargo, a煤n no est谩 claro el efecto del tratamiento periodontal sobre el perfil ateroscler贸tico y la prevenci贸n de futuros eventos. El objetivo de esta revisi贸n narrativa es establecer la relaci贸n entre ambas patolog铆as y el efecto del tratamiento periodontal sobre los par谩metros prote铆na C-reactiva (PCR), fibrin贸geno, triglic茅ridos, colesterol total, HDL, LDL, VLDL, IL-6, TNF-伪 y leucocitos totales. La evidencia cient铆fica analizada demuestra que, en pacientes con periodontitis, el tratamiento periodontal es efectivo cuando hay enfermedad cardiovascular, mejorando significativamente el perfil ateroscler贸tico, respecto a los pacientes sanos, en quienes s贸lo en casos aislados se observa mejora
Evaluation of Bone Gain and Complication Rates after Guided Bone Regeneration with Titanium Foils: A Systematic Review
Guided bone regeneration techniques are increasingly used to enable the subsequent placement of dental implants. This systematic review aims to analyze the success rate of these techniques in terms of bone gain and complications rate using titanium membranes as a barrier element. Electronic and hand searches were conducted in PubMed/Medline, Scielo, Scopus and Cochrane Library databases for case reports, case series, cohort studies and clinical trials in humans published up to and including 19 September 2020. Thirteen articles were included in the qualitative analysis. Bone gain both horizontally and vertically was comparable to that obtained with other types of membranes more commonly used. The postoperative complication rate was higher that of native collagen membranes and non-resorbable titanium-reinforced membranes, and similar that of crosslinked collagen membranes and titanium meshes. The survival rate of the implants was similar to that of implants placed in native bone. Due to the limited scientific literature published on this issue, more randomized clinical trials comparing occlusive titanium barriers and other types of membranes are necessary to reach more valid conclusions
Analysis of Healthy Lifestyle Habits and Oral Health in a Patient Sample at the Dental Hospital of the University of Barcelona
The association between general health and oral health has been studied over recent years. In order to evaluate the lifestyle and the presence of healthy habits, a descriptive observational study was conducted from December 2018 to April 2019 with 230 patients, aged from 18 to 65 years old, that attended the Dental Hospital of the University of Barcelona for the first time. A total of 230 participants were considered, 98 (43%) were men and 132 (57%) were women, with a mean age of 37 years old. Our hypothesis was that patients with healthy habits had a better oral status in comparison with patients with bad lifestyle habits. No statistically significant results were found regarding oral hygiene between gender, smokers and patients with systemic pathology. Regarding a healthy lifestyle (High adherence to dietary intake), no statistically significant results were found. No significant differences were found regarding physical activity between male and female patients. Our hypothesis wasn't confirmed; therefore, we cannot conclude that patients with healthy habits have better oral status in comparison with patients with bad lifestyle habits. Consequently, more prospective longitudinal studies should be carried out
Systemic antibiotic prophylaxis to reduce early implant failure: a systematic review and meta-analysis
Systemic antibiotics are routinely prescribed in implant procedures, but the lack of consensus causes large differences between clinicians regarding antibiotic prophylaxis regimens. The objectives of this systematic review are to assess the need to prescribe antibiotics to prevent early implant failure and find the most appropriate antibiotic prophylaxis regimen. The electronic search was conducted in PubMed/MEDLINE, Scielo and Cochrane Central Trials Database for randomized clinical trials of at least 3 months of follow-up. Eleven studies were included in the qualitative analysis. Antibiotics were found to statistically significantly reduce early implant failures (RR = 0.30, 95% CI: 0.19-0.47, p < 0.00001; heterogeneity I2 = 0%, p = 0.54). No differences were seen between preoperative or both pre- and postoperative antibiotic regimens (RR = 0.57, 95% CI: 0.21-1.55, p = 0.27; heterogeneity I2 = 0%, p = 0.37). A single preoperative antibiotic prophylaxis dose was found to be enough to significantly reduce early implant failures compared to no antibiotic (RR = 0.34, 95% CI: 0.21-0.53, p < 0.00001; heterogeneity I2 = 0%, p = 0.61). In conclusion, in healthy patients a single antibiotic prophylaxis dose is indicated to prevent early implant failure
Periodontal treatment on patients with cardiovascular disease : systematic review and meta-analysis
Atherosclerotic cardiovascular disease is the main cause of mortality in developed countries. It is a chronic and systemic inflammatory disease with a multifactorial etiology. Periodontal disease is one of the many factors that contribute to its development. To analyze the effects of periodontal treatment on cardiovascular risk parameters in patients with atherosclerotic cardiovascular disease. A systematic research was conducted in the Pubmed/Medline databases for clinical trials published up to and including the year 2017. Ten articles were included for analysis. Periodontal treatment reduced C-reactive protein levels (77.8% of clinical trials), tumor necrosis factor-alpha (66.7%), interleukin-6 (100%) and leukocytes (50%). Fibrinogen levels also improved considerably (66.7%). Effects on lipid parameters were more limited, whereby only oxidized low density lipoprotein and very low density lipoprotein cholesterol decreased significantly. Meta-analysis showed a statistically significant decreased in C-reactive protein and leukocytes values when patients were submitted to non-surgical periodontal treatment in contrast to receiving no treatment at all (mean difference 1.199 mg/L, 95% confidence interval: 1.100-1.299, p<0.001; and mean difference 0,79 g/L, 95% confidence interval: 0.717-0.879, p<0.001, respectively). Periodontal treatment has a beneficial effect on some of the biochemical parameters considered to represent cardiovascular risk. Further randomized clinical trials are necessary, with longer follow-up periods including regular periodic monitoring, in order to determine the extent of the impact of periodontal treatment
Titanium Meshes in Guided Bone Regeneration: A Systematic Review
The presence of satisfactory bone volume is fundamental for the achievement of osseointegration. This systematic review aims to analyse the use of titanium meshes in guided bone regeneration in terms of bone gain, survival and success rates of implants, and percentages of exposure. An electronic search was conducted Articles were selected from databases in MEDLINE (PubMed), SCOPUS, Scielo, and Cochrane Library databases to identify studies in which bone regeneration was performed through particulate bone and the use of titanium meshes. Twenty-one studies were included in the review. In total, 382 patients, 416 titanium meshes, and 709 implants were evaluated. The average bone gain was 4.3 mm in horizontal width and 4.11 mm in vertical height. The mesh exposure was highly prevalent (28%). The survival rate of 145 simultaneous implants was 99.5%; the survival rate of 507 delayed implants was 99%. The success rate of 105 simultaneous implants was 97%; the success rate of 285 delayed implants was 95.1%. The clinical studies currently available in the literature have shown the predictability of this technique. It has a high risk of soft tissue dehiscence and membrane exposure although the optimal management of membrane exposition permits obtaining a sufficient bone regeneration volume and prevents compromising the final treatment outcome
Epstein鈥揃arr Virus and Peri-Implantitis: A Systematic Review and Meta-Analysis
The exponential growth in the use of dental implants in the last decades has been accompanied by an increase in the prevalence of peri-implant disease. It appears that viruses may have pathogenic potential for the development of this pathology. The objective of this systematic review is to study the possible association between the presence of Epstein-Barr virus and the development of peri-implantitis. An electronic search was conducted in PubMed/MEDLINE, Scielo and Embase databases for cross-sectional and case-control studies in humans published up to and including 4 January 2021. Five studies were included in the qualitative analysis. The meta-analysis did not show a statistically significant difference regarding the prevalence of Epstein-Barr virus in the peri-implant sulcus between implants with peri-implantitis and healthy implants. In conclusion, no association between the human herpesvirus 4 and peri-implantitis was found. Further research on this topic is essential to develop more effective treatments
Narrow Diameter Dental Implants as an Alternative Treatment for Atrophic Alveolar Ridges. Systematic Review and Meta-Analysis
To determine the marginal bone loss and the survival, success and failure rates of narrow dental implants, a systematic literature search was carried out in the MEDLINE (Pubmed), Cochrane, Scopus, and Scielo databases for articles published between 2010 and 2021. The exclusion criteria were: systematic reviews, case reports, expert opinions; animal studies; samples of less than 10 subjects; follow-up periods of less than 36 months; smokers of minimum 10 cigarettes/day; and articles about mini-implants for orthodontic anchorage. Meta-analyses were performed to assess marginal bone loss and implant survival, success, and failure rates. Fifteen studies were included: 7 clinical trials, 3 randomized clinical trials, 3 cohort studies, and 2 case series. The total number of subjects was 773, in whom 1245 implants were placed. The survival rate for the narrow diameter implants was 97%, the success rate 96.8%, and the failure rate 3%. Marginal bone loss was 0.821 mm. All these data were evaluated at 36 months. Based on the literature, it can be considered that there is sufficient evidence to consider small diameter implants a predictable treatment option. These show favorable survival and success rates and marginal bone loss. All of them are comparable to those of standard diameter dental implants
The application of beta-tricalcium phosphate in implant dentistry: a systematic evaluation of clinical studies
The demand for synthetic graft materials in implant dentistry is rising. This systematic review aims to evaluate the survival rate of dental implants placed simultaneously with bone regeneration procedures using the material -tricalcium phosphate, one of the most promising synthetic graft materials. The electronic search was conducted in PubMed, Scielo, and the Cochrane Central Register of Controlled Trials. There were five randomized clinical trials, one of which was a non-randomized controlled clinical trial and four of which were observational studies without a control group included. Implant survival rate and other clinical, radiographic, and histological parameters did not differ from those of implants placed simultaneously with another type of graft material, or placed in blood clots or natural alveolar ridges. Based on the available literature, - tricalcium phosphate seems to be a promising graft material in implant dentistry. Nevertheless, more randomized clinical trials, with long follow-up periods, preoperative and postoperative CBCT, and histological analysis, are necessary to assess its long-term behavior
