This study quantified alterations in root dentin permeability after exposure to different acid beverages. Twenty-five third molars were sectioned below the cementoenamel junction, the root segment was collected, and the pulp tissue was removed. The root segments were connected to a hydraulic pressure apparatus to measure the permeability of root dentin after the following sequential steps, with 5 specimens in each: 1) phosphoric acid etching for 30 s (maximum permeability), 2) root planning to create new smear layer, 3) exposure to different acid substances for 5 min (orange, cola drink, vinegar, white wine, lemon juice), 4) toothbrushing with sonic toothbrush for 3 min, 5) toothbrushing with sonic toothbrush plus dentifrice for 3 min. Considering step I as 100%, the data were converted into percentage and each specimen was its own control. Data were analyzed statistically by Kruskal-Wallis and Dunn's post test at 5% significance level. All acidic substances increased dentin permeability significantly after scraping (p<0.05). Toothbrushing after exposure to acid substances decreased dentin permeability and the association with dentifrice accentuated the decrease (p<0.05), except for the specimens treated with cola drink. Thus, it may be concluded that all tested acid fruit juices increased dentin permeability, and toothbrushing with or without dentifrice can decrease root dentin permeability after dentin exposure to acid diet.

Factors associated with dentine hypersensitivityseverity in Colombian dental patients.Cite as: López L, Espana P, Bastidas R, Fuelagan J & Mafla AC. Factors associated with dentine hypersensitivity severity in Colombian dental patients. J Oral Res 2016; 5(2): 63-70. Abstract: Introduction: The aim of this study was to determine the prevalence of dentine hypersensitivity (DH) and examine associated etiological factors related to the severity of DH in dental clinic patients treated at the School of Dentistry at Universidad Cooperativa de Colombia, Pasto, Colombia. Materials and Methods: A cross-sectional study was designed in which three hundred and thirty three patients aged 15 to 44 years old were assessed for the presence and severity of DH. The dentine hypersensitivity diagnosis was based on self-reported sensitivity and a clinical examination. The questionnaire included socio-demographic information, data about oral health habits and acidic dietary intake. A descriptive analysis was performed and the association between DH severity and risk factors was determined using an ordinal logistic regression model. Results: Dentine hypersensitivity was detected in 88 out of 333 (26.4%) subjects (95% CI: 21.83-31.56). The pH of natural juices (OR=6.013; 95% CI: 0.995-36.319, p=0.051) and pH of alcohol beverages (OR= 7.800; 95% CI: 2.282-26.658, p=0.001) were significantly associated with the severity of dentine hypersensitivity. Conclusions: The results indicated that the prevalence of dentine hypersensitivity in these patients was consistent with previous reports. Furthermore, the severity of DH was influenced by acidic diet. These results suggest that dental counseling should be provided to all patients as well as to those with dentine hypersensitivity to prevent the occurrence of this oral health problem and the severity of symptoms.

“…[6][7][8] Furthermore, the tooth brushing subsequent to the assumption of dietary acids may enhance the exposure of the dentinal tubules and aggravate the DH. 7,9 Desensitizing bioactive materials involved in the treatment of DH should be able to react with body fluids and/or saliva depositing hydroxycarbonate apatite (HCA) within the demineralized collagen fibrils and occluding dentinal tubules. 10,11 Mineralizing processes may also occur via the tubular fluid, which is very similar to the extracellular fluid and, in conjunction with the odontoblast processes, orchestrates mineralization processes.…”

The bioactive glass (Sylc) reacts with saliva depositing hydroxycarbonate apatite (HCA) within the demineralized collagen fibrils and occluding dentinal tubules. Therefore, it may be used as a suitable desensitizing bioactive material for the treatment of DH and as an air-cutting powder before bonding procedures to remineralize tooth structure and/or prevent further demineralization within the resin-dentin interface. SUMMARYThe aim of this study was to evaluate the dentin remineralization induced by bioactive substances contained in common dental materials used in preventive and operative dentistry. Several materials were applied on human dentin segments. Dentin permeability was quantified using a fluid filtration system working at 20 cm H 2 O. Micro-Raman, SEM-EDX, and microhardness calculation were used to evaluate changes in the mineralization of dentin. Dentin treated with the prophylactic materials showed different dentin permeability values, in particular subsequent to immersion in remineralizing solutions (RSS). The bioactive glass (Sylc) was the only substance able to reduce dentin permeability after immersion in remineralizing solution and to show hydroxyapatite precipitation as a sign of dentin remineralization. The reduction in dentin permeability obtained after the application of the other prophylactic mate-
