Objetivos: Evaluar los efectos de agentes remineralizantes a base de fosfato de calcio en la obliteración de túbulos dentinarios y dispersión de energía en la dentina cervical. Material y métodos: Treinta especímenes de dentina cervical bovina fueron previamente erosionados (ácido clorhídrico al 0,6 %, pH 2,3; 5 min) y divididos aleatoriamente en 3 grupos (n = 10): Control – sin tratamiento, NP – Desensibilize Nano P (FGM®) y RD – MI Paste Plus (RecaldentTM). Los tratamientos fueron aplicados en cuatro sesiones con intervalos de 7 días. Los especímenes fueron analizados por microscopia electrónica de barrido (MEB) y espectroscopia de rayos X de energía dispersiva (EDX). Resultados: Los grupos NP e RD mostraron mayor obliteración de túbulos dentinarios que el grupo control (p < 0,05). Las concentraciones de Ca/P fue...

Dentine hypersensitivity is defined as short, sharp pain from exposed dentin in reaction to thermal, evaporative, tactile, osmotic, or chemical stimuli. This condition is associated with non-carious cervical lesions (erosion, abrasion and abfraction), gingival recessions, periodontal disease, among other dental problems. Due to its multifactorial nature, the diagnosis of dentin hypersensitivity is often difficult and confusing for the dental surgeon. There is no single strategy that can solve this condition in all patients and it is the responsibility of the dental surgeon to know its characteristics in order to propose an effective treatment plan for patients. Therefore, this review aims to show the main characteristics of dentin hypersensitivity, as well as the challenges associated with clinical management, for understanding and mastery in clinical practice.

Dental erosion is the progressive loss of the dental structure associated with acids of non-bacterial origin and with irreversible effects. The consumption of beverages and foods with high acid content corresponds to the main extrinsic factor of dental erosion, while the endogenous acids that project into the mouth through the esophagus during vomiting or regurgitation are part of the intrinsic factors that contribute to this injury. The prevention and treatment of eroded teeth are real challenges in dental practice. Therefore, this article aims to collect information available in the current literature on the etiology, clinical characteristics and treatment of erosive dental wear, to provide a practical guide for dental surgeons and students.

Objective: To determine the prevalence of oral health problems and dental anxiety in rural older adults, and their impact on oral health-related quality of life (OHRQoL). Methods: A crosssectional descriptive and analytical study was conducted among older adults in San Juan de Siguas, Arequipa, involving 64 participants aged 60 and above who provided informed consent. Sociodemographic, clinical, and oral health data were collected through structured interviews, using the Modified Dental Anxiety Scale (MDAS) and the OHIP-5 questionnaire to assess dental anxiety and OHRQoL, respectively. Binary logistic regression was applied to analyze the relationship between dental anxiety and OHRQoL, adjusting for relevant variables. Results: Participants had an average age of 68.5 years, the majority were women (54.7%), and most lacked health insurance (85.9%). All participants had decayed teeth, and ...
