RESUMO
Background: Oral diseases and their impact on health and quality of life have now evolved into a polarized epidemiological state in which their incidence is especially affecting the most vulnerable in the population: the elderly, especially those with low incomes economical. On the other hand, the noticeable increase observed in the proportion of older adults in developing countries such as Iraq during the last decades. Such a high proportion of older adults is causing an increase in their stomatological care needs that necessitate dentists to know precisely both the etiological factors, such as the pathogenesis and factors that determine the specificity of oral disorders at this stage of life. Only with this knowledge will professionals be able to face these patients with a modern dentistry based on prevention. The objective of the study was to show the impact of oral health on the quality of life of older adults in Iraq. Materials and Methods: A cross-sectional study was conducted in Iraqi adults focused on demographic characteristics factors, lifestyle, the Geriatric Oral Health Index, and Oral Health Diagnosis. Data were evaluated using ratios, the Chi-square analysis for the correlation among factors and odds ratios to verify statistical significance at P ≤ 0.05. Results: This research confirms the impact of oral health on the quality of life of older adults in Iraq. Endodontic problems compromise the quality of life of older adults. Conclusion: Oral health problems, especially those of traumatic, endodontic, and periodontal origin, negatively affect the quality of life of older adults in Iraq.
RESUMO
Background: Factors like medical and periodontal conditions, implant location and smoking can affect marginal bone loss (MBL) of basal implants. Objectives: The purpose of this study is to explore the association of MBL with multiple variables including gender, age, smoking status, diabetes, implant placement protocol, location of implant, and type of prosthesis. Material and Methods: A total of 156 single-piece basal implants (Dr. Ihde Dental AG in Gommiswald, Switzerland) were placed in 44 patients. Dental panoramic tomographs were obtained postoperatively and following a one-year of service to determine MBL on mesial and distal sides. The association of MBL with the multiple variables was analysed using the multivariate and the random forest analysis. Results: The mean mesial and distal MBL was 0.64 millimetres. None of the implants presented MBL exceeding 1 millimetre. All implants were retained without complications during the firstyear of service. The MBL was remarkably associated with the smoking status, diabetes, location of implant and implant placement protocol. Diabetes mellitus is the most vital parameter in predicting MBL. Conclusion: The mean MBL of all implants did not exceed the threshold of 1 millimetre during the first year of service. When placing implants in patients who smoke and have diabetes, care should be taken.
Antecedentes: Factores como las condiciones médicas y perio-dontales, la ubicación del implante y el tabaquismo pueden afectar la pérdida marginal de hueso (PMH) de los implantes basales. Objetivo: La finalidad de este estudio es explorar la asociación de PMH con múltiples variables, incluido el sexo, la edad, el tabaquismo, la diabetes, el protocolo de colocación del implante, la ubicación del implante y el tipo de prótesis. Material y Métodos: Se colocaron 156 implantes basales de una sola pieza (Dr.Ihde Dental AG, Gommiswald, Suiza) en 44 pacientes. Se obtuvieron tomografías panorámicas dentales después de la operación y después de un año de servicio para deter-minar la MBL en los lados mesial y distal. La asociación de la PMH con las múltiples variables se analizó mediante el análisis multivariado y de bosque aleatorio. Resultados: La PMH media mesial y distal fue de 0,64 milímetros. Ninguno de los implantes presentó PMH superior a 1 milímetro. Todos los implantes se mantuvieron sin complicaciones durante el primer año de servicio. La PMH se asoció nota-blemente con el tabaquismo, la diabetes, la ubicación del implante y el protocolo de colocación del implante. La diabetes mellitus es el paráme-tro más importante para predecir la MBL. Conclusion: La PMH media de todos los implantes no superó el umbral de 1 milímetro durante el primer año de servicio. Se debe tener especial cuidado al colocar implantes en pacientes que fuman y tienen diabetes.

OBJECTIVES: The aim of this study was to develop a new method of obturation by warm sealer in conjunction to single cone gutta-percha and evaluate the suitability of this technique to obturate complex root canal systems. METHODOLOGY: Three root canal sealers namely, AH Plus, BioRoot RCS, GuttaFlow and a prototype sealer composed of tricalcium silicate and 30% zirconium oxide mixed with water and water-soluble polymer were investigated. The sealers were tested for flow, film thickness, setting time and radiopacity following ISO 6876 (2012) recommendations at room temperature and following heat application at 100°C to change the sealer properties. All the test sealers were characterized by scanning electron microscopy and energy dispersive spectroscopy. The volume of voids when used with a single cone obturation technique both unmodified and modified by heat was evaluated using microcomputed tomography. RESULTS: Although the prototype sealer was designed to be similar to the BioRoot, its physical properties were found to be different. All sealers tested were affected by the heat and exhibited a change in the physical properties mainly the setting time, flow, film thickness and void volume. CONCLUSIONS: The application of heat affected the sealer properties and void volume. The single cone obturation technique may not be suitable for complex canal anatomy and furthermore, AH Plus should not be subjected to high temperatures as its properties deteriorate and void volume increases.
