“…Hay una larga historia de los modelos matemáticos para las etapas iniciales de la caries dental, y casi todos ellos consideran las condiciones apropiadas para la aplicación de las Leyes de Fick, por ejemplo Gray (1962); Holly and Gray (1968);Patel et al (1987a,b); Wu et al (1976);Zimmerman (1966a,b,c). En particular haciendo referencia a los trabajos de Zimmermand (Zimmerman (1966c)) y Patel (Patel et al (1987b)) popdemos decir que las teorías generales de la matemática aplicada a la propagación de las caries dentales pueden ser mejoradas significativamente haciendo nuevas aportaciones en el nivel de complejidad de los modelos con relación a los experimentos realizados.…”

“…19 Conversely, the enamel layer can be affected adversely through acid-induced dissolution processes associated with dental caries or erosion from the modern diet. [20][21][22] Acid attack of HAP is reasonably described by the following reaction: 23 Ca10(PO4)6(OH)2 (S) + 8H + (aq) ⇌ 10 Ca 2+ (aq) + 6HPO4 2-(aq) +2 H2O (1) This is the primary process of tooth demineralization: protons react with HAP, which releases Ca 2+ and HPO4 2-ions into the solution, 15,24,25 coupled with further solution processes (vide infra).…”

“…13,14,23,26 The main approach, with well-defined mass transport, used in studies of enamel and HAP dissolution is the rotating disk (RD) method. [27][28][29][30][31][32][33] However, while RD method it is often restricted to bulk solution measurements which places severe limitations on the time and spatial resolution of the technique.…”

A combination of scanning electrochemical cell microscopy (SECCM) and atomic force microscopy (AFM) is used to quantitatively study the acid-induced dissolution of dental enamel. A micron-scale liquid meniscus formed at the end of a dual barrelled pipette, which constitutes the SECCM probe, is brought into contact with the enamel surface for a defined period. Dissolution occurs at the interface of the meniscus and the enamel surface, under conditions of well-defined mass transport, creating etch pits that are then analysed via AFM. This technique is applied to bovine dental enamel, and the effect of various treatments of the enamel surface on acid dissolution (1mM HNO 3) is studied. The treatments investigated are zinc ions, fluoride ions and the two combined. A finite element method (FEM) simulation of SECCM mass transport and interfacial reactivity, allows the intrinsic rate constant for acid-induced dissolution to be quantitatively determined. The dissolution of enamel, in terms of Ca 2+ flux ( 2+ ), is first order with respect to the interfacial proton concentration and given by the following rate law:, with 0 = 0.099 ±0.008 cm.s -1 . Treating the enamel with either fluoride or zinc slows the dissolution rate, although in this model system the partly protective barrier only extends around 10-20 nm into the enamel surface, so that after a period of a few seconds dissolution of modified surfaces tends towards that of native enamel. A combination of both treatments exhibits the greatest protection to the enamel surface, but the effect is again transient.

“…It has been reported that food with pH less than 5.5, act as a corrodent and demineralize the teeth. [22][23][24] Carbonated beverages are cited as a cause of tooth decalcification and their corrosive effect was found to be due to added citric and phosphoric acid. [25][26][27][28] Drinking with an increasing flow rate and with decreasing outlet diameter could increase the erosion depth.…”

Regressive alteration is a multifactorial condition causing loss of enamel and dentine. The cause is generally erosion, abrasion, abfraction, attrition and resorption or a combination of these lesions. Progression of regressive changes is found to be slow with periods of activity and inactivity. Although restorations are indicated, prevention remains the prime strategy in maintaining the longevity of a tooth. A thorough knowledge of the etiology, signs and symptoms of these lesions is of utmost importance in the diagnosis and management. Conclusion and clinical implications This article describes the etiological factors and assists the readers in reaching a diagnosis on the type of lesion and their appropriate management.
