Peri-implantitis in patients without regular supportive therapy: Prevalence and risk indicators.

OBJECTIVES: To determine the prevalence of peri-implant diseases in patients treated in a university setting without a regular peri-implant supportive therapy schedule, and to identify the risk indicators associated with peri-implantitis. MATERIAL AND METHODS: A retrospective cohort study was made of patients with dental implants with at least 12 months of functional loading who did not receive regular peri-implant supportive therapy. Patient- and implant-related variables were retrieved, and clinical and radiological examinations were performed. Descriptive and bivariate analyses and multilevel logistic regression analyses were performed to identify factors associated with peri-implantitis. RESULTS: A total of 213 implants in 88 patients were analyzed. The patient-level prevalence of peri-implantitis and peri-implant mucositis was 26.1% (95%CI: 16.7%-35.5%) and 44.3% (95%CI: 34.0%-54.6%), respectively. Peri-implant diseases were significantly more frequent when the width of the keratinized mucosa was < 2 mm (OR = 5.26; 95%CI: 1.24-22.26; p = 0.024), and when there was 12 month post-loading bone loss (OR = 2.96; 95%CI: 1.35-6.52; p = 0.007). CONCLUSIONS: Peri-implantitis is a common finding in patients without regular peri-implant supportive therapy (prevalence 16.7-35.5%). A thin peri-implant keratinized mucosa (< 2 mm) and a higher degree of bone remodeling after loading seem to be the main risk factors for peri-implantitis in this patient profile. CLINICAL RELEVANCE: Patients who do not engage in supportive peri-implant maintenance have a higher risk of peri-implantitis. A thin keratinized mucosa and bone loss during the first year of loading are predisposing factors for peri-implantitis.

In Vitro Characterization of an Anodized Surface of a Dental Implant Collar and Dental Abutment on Peri-Implant Cellular Response.

The purpose of this paper was to determine the effect of anodization on the in vitro proliferation and adhesion of immortalized human keratinocytes (HaCats) and mouse bone marrow-derived mesenchymal stem cells (BM-MSCs) in Titanium Grade 23 (Ti6Al4V ELI) discs and to describe the surface topography, roughness, and composition of dental implants (body and collar) and abutments submitted to an area-specific anodization process. HaCat cells and BM-MSCs were seeded onto discs with three different surface treatments: machined, area-specific anodization for abutments, and area-specific anodization for implant collars. Cell proliferation was assessed using a resazurin-based fluorescent dye on days 1, 3, and 7, while cell adhesion was examined using scanning electron microscopy (SEM). Surface topography, roughness, and composition were evaluated for six implant bodies with an anodized rough surface, six anodized implant smooth collars, and six anodized prosthetic abutments. Both HaCats and BM-MSCs showed increased viability over time (p < 0.001) with no statistically significant differences among the different surfaces (p = 0.447 HaCats and p = 0.631 BM-MSCs). SEM analysis revealed an enhanced presence and adhesion of HaCat cells on the anodized surface for the implant collars and an increased adhesion of BM-MSCs on both the anodized and machined surface abutments. The topography characteristics of the treated implants and abutments varied depending on the specific implant region. Chemical analysis confirmed the presence of oxygen, calcium, phosphorus, and sodium on the anodized surfaces. The area-specific anodization process can be utilized to create variable topography, increase the specific surface area, and introduce oxygen, calcium, phosphorus, and sodium to dental implants and abutments. While BM-MSCs and HaCat cells showed similar adhesion and proliferation on anodized and machined surfaces, a positive interaction between anodized Ti6Al4V ELI surfaces and these two cell lines present in the peri-implant mucosa was observed. Due to the limitations of the present study, further research is necessary to confirm these findings.

Preorthodontic dilacerated incisive crown modification in a pediatric patient: a case report.

Dental dilacerations are abrupt deviations of the longitudinal axis of the crown or root portion of the tooth, caused by traumatic axial displacement of previously formed hard tissue in relation to the developing soft tissue. CASE PRESENTATION: A 13-year-old boy in good general health was referred for root canal treatment of the maxillary left central incisor, for which abnormal crown morphology impeded orthodontic treatment. He presented bilateral crown dilaceration at both maxillary central incisors. Treatment involved a CAD/CAM milled veneer of the maxillary left central incisor and semidirect warm composite veneer of the maxillary right central incisor. Follow-up and monitoring of the restoration was performed through .stl file analysis. DISCUSSION: Crown dilaceration severity assessment is crucial for deciding the best treatment plan for each case. In this patient, additive restorative protocols, CBCT, and 3D digital model analysis were the most useful aids by providing key multidisciplinary information. CONCLUSION: A multidisciplinary treatment workflow with a minimally invasive approach aided by digital tools such as CBCT and CAD/CAM technologies is useful to achieve successful and predictable outcomes in crown dilaceration cases.

Prevalence of Periodontitis among Patients Diagnosed with Marfan Syndrome: A Cross-Sectional Study Comparing Samples of Healthy Patients.

Periodontitis is an inflammatory condition caused by a bacterial plaque and characterized by progressive destruction of the tooth-supporting apparatus. Patients with Marfan syndrome (MFS) exhibit a connective tissue disorder, which can also affect oral soft and hard tissue. Thus, the aims of this cross-sectional study were to assess the association between periodontitis and MFS and secondly, to compare periodontal parameters and prevalence of disease with a control group (CG) without MFS. 152 patients (MFS = 76, CG = 76) were recruited to evaluate the following periodontal parameters: probing depth, gingival margin, clinical attachment level, plaque index, and bleeding on probing. The 2017 World Workshop guideline was followed for the diagnosis of the periodontal status. A multivariate analysis was performed using a multinomial logistic regression adjusted for age, gender, and smoking. The level of significance required was p < 0.05. Patients with MFS did not show a higher prevalence of periodontitis compared to the CG. However, patients with MFS did have higher values in probing depth, gingival recession, clinical attachment level, and plaque index compared to the CG patients (p < 0.05). In conclusion, although similar prevalence of periodontitis was found among the studied groups, MFS patients showed worse periodontal parameters.

Assessment of Dental Implants with Modified Calcium-Phosphate Surface in a Multicenter, Prospective, Non-Interventional Study: Results up to 50 Months of Follow-Up.

Prescription of implant treatments is very widespread at present, mainly due to the low rate of annual loss and, to date, few studies have assessed their survival in the routine clinical practice of dentistry. The purpose of this observational study was to evaluate the effectiveness of dental implants with a calcium-phosphate surface in the daily practice of dental clinics. A multicenter, prospective, non-interventional, observational study was performed, in which three experienced practitioners (one maxillofacial and two oral surgeons) inserted implants using standard external and internal hexagon connections in adult patients requiring ≥1 osseointegrated implants to replace missing teeth. Follow-up was performed for 24 months after implant loading. Two hundred and twelve subjects were included (51.5% men), with a mean age of 51.2 ± 11.90 years, in whom 544 implants were inserted. 87.2% of the patients received 1⁻4 implants. The preferred connection system was internal hexagon (73.5%). There were nine failures, with an interval survival rate (ISR) at 24 months of 100% and a cumulative survival rate (CSR) of 98.3%. In conclusion, implants with a modified calcium-phosphate surface are associated with a high rate of survival and may be considered a method of choice in clinical practice.

Association of burning mouth syndrome with xerostomia and medicines.

OBJECTIVE: A case control study to identify risk factors for burning mouth syndrome (BMS). MATERIAL AND METHODS: Quantitative analysis was carried out on the total salivary flow at rest and stimulated; subjective xerostomia, ingestion of medicines and the psychological states of anxiety and depression in 40 patients with BMS and 40 controls. RESULTS: The ANOVA analysis showed significant differences in the means of the number of medicines/day, number of xerostomising agents/day, subjective xerostomia, anxiety and depression, between the groups studied. No significant differences were seen in the at rest or stimulated saliva flow rates. The odds ratio analysis determined the association of BMS with xerostomia and the consumption of hypotensives and diuretics. CONCLUSIONS: From the results of this study, it can be shown that the consumption of hypotensives and diuretics was a risk factor for the development of BMS. The function of the salivary glands in patients with BMS is not affected.

La función masticatoria en el anciano / Masticatory function in elderly people

La función oral está intrínsecamente relacionada con actividades diarias esenciales como la alimentación y la comunicación. Además tiene un papel fundamental en las relaciones del individuo con otras personas y en la conservación del autoestima. Con el envejecimiento se producen cambios en las estructuras bucodentales que, junto a la variación del estado de salud oral y general, determinan el deterioro habitual de la función oral. No obstante, las personas mayores suelen adaptarse a muchos de los cambios del sistema estomatognático, conducentes muchas veces a limitaciones en la función oral. En este artículo se hace una breve revisión de los cambios de la función oral en el anciano centrada en la masticación (AU)

La salud bucodental de los españoles mayores de 64 años. Impacto en el estado de salud individual / Oral health in Spaniards older than 64. Impact in the individual health

Introducción: los cambios epidemiológicos sufridos en los países occidentales en el siglo XX han propiciado un aumento del número absoluto y de la proporción de ancianos en todos ellos. Pacientes y Método: se realizó un estudio descriptivo transversal de prevalencia de enfermedades bucodentales en una población de 3.460 individuos en 7 Comunidades Autónomas españolas, tanto institucionalizados (10 por ciento) como no institucionalizados (90 por ciento). Resultados: la edad media de los encuestados fue de 73,67 años. Un 31,4 por ciento de los individuos del estudio eran desdentados totales. Los individuos dentados presentaban un promedio de 14,88 dientes. El CAOD de los individuos de la muestra fue de 20,8-10, siendo de 23,7-9,8 en los institucionalizados La última visita al dentista había sido de media 4 años y medio antes, pero los institucionalizados hacía 7 años Discusión: es totalmente inaceptable que la prevención y el tratamiento las enfermedades bucodentales, especialmente entre las personas de edad más avanzada, se sigan considerando como un aspecto totalmente optativo para el mantenimiento de la salud del individuo. Estudios epidemiológicos, bacteriológicos e inmunológicos demuestran que la enfermedad periodontal o la caries pueden ser las causantes de un importante aumento de la morbimortalidad especialmente entre las personas de más edad (AU)
