“…The in-office treatment phase began with the removal of plaque and white spots from the tooth surfaces using a nylon brush with a low-speed rotating instrument and non-abrasive cleaning paste. Anterior and premolar teeth were isolated with a double arch rubber dam (OptiDam, Kerr, Bioggio, Switzerland), with the edges of the perforations inverted in the gingival sulcus and silk ligatures on the tooth necks [19]. The product used for bleaching was a chemoactivated bleaching agent whose active ingredient was hydrogen peroxide at a concentration of 40% (Boost, Ultradent, South Jordan, USA); the product was delivered using a double syringe and, when mixed, acquired a (red-colored) gel consistency.…”

Combined Vital Tooth Whitening: Effect of Number of In-Office Sessions on the Duration of Home Whitening. A Randomized Clinical Trial

Background: In cases of moderate to severe dental discoloration, vital tooth whitening usually requires a prolonged treatment time if it is to obtain satisfactory outcomes. Variations in the clinical efficacy of whitening products in terms of their concentration and application time mean that we need to be aware of the real bleaching capacity of each whitening method and each product. This randomized clinical trial aimed to analyze with a spectrophotometer the effect of the number of in-office vital tooth whitening sessions (one or two) on the number of weeks of ensuing home whitening until color stability was obtained. Methods: Twenty patients with moderate/severe discoloration were treated with combined vital tooth whitening. Ten patients were treated with a single in-office session consisting of two applications of a product containing 40% hydrogen peroxide, followed by home treatment with individualized splints and a 16% carbamide peroxide gel (Group 1S). The other ten patients (Group 2S) were treated in two in-office sessions with two applications of the same product as Group 1S, followed in the same way by home treatment. Results: Comparing the two groups (1S and 2S), no significant differences in Euclidean distance (ΔE) were found after in-office whitening, or when color stabilization was obtained and home whitening ceased. Significant differences in the number of weeks of home whitening until color stabilization reached the same outcomes were found between 1S and 2S; 1S required a mean of 11.6 weeks home whitening, while 2S required 8.2 weeks. Conclusions: Combined tooth whitening with two in-office sessions significantly reduces the number of weeks (by three to four weeks) of subsequent home tooth whitening needed to reach color stabilization.

“…Color difference (ΔE, ΔE = (ΔL 2 + Δa 2 + Δb 2 ) 1/2 ) is generally used to present the degree of color change. [19,27,46] ΔE combines three parameters of L, a, and b, but it does not indicate the direction in which teeth increase/decrease whitening. [19,27,46] To this end, we defined a new parameter whiteness (W, W = L − |a| − |b|) to comprehensively quantify the degree of tooth whitening.…”

“…[13,16,17] Oxidative bleaching agents, especially hydrogen peroxide (H 2 O 2 ) and carbamide peroxide (release H 2 O 2 when contacts water), have been widely applied to tooth whitening in clinical practices. [16,[18][19][20] But H 2 O 2 can roughen tooth surface and thus provide more favorable conditions for the re-staining and bacterial recolonization. [21][22][23] In addition, H 2 O 2 and carbamide peroxide are also irritating to gingival and mucosal tissues.…”

Tooth staining and biofilm formation are major challenges for dental healthcare around the world. Herein, a bifunctional photodynamic dental therapy (PDDT) strategy is designed based on zwitterion-modified porphyrin (ZMP) prepared by the conjugation of protoporphyrin IX (PP) and a superhydrophilic zwitterion moiety for tooth whitening and biofilm eradication. The electron donor-acceptor structure and water solubility of ZMP increases its reactive oxygen species output to ≈8 times compared with PP under purple light irradiation. Results show that this new strategy can not only nondestructively whiten teeth by degrading the chromogen, but also eradicate ≈95% of the biofilm by disintegrating the extracellular polymeric substances. This study highlights the superiority of ZMP as a photosensitizer and opens new avenues in exploring PDDT for clinical dentistry to whiten teeth and treat biofilm-induced dental diseases.

“…In recent years, tooth whitening has become a widely used technique as it is safe, economically feasible, and minimally invasive. It eliminates internal and external discolorations from teeth and camouflages white spots on the surface by increasing the general luminosity of the affected tooth [17,18]. Another option is remineralization with fluoride or casein phosphopeptide, which can also produce good results when restoring the surface layers of caries lesions.…”

Dental Treatment of White Spots and a Description of the Technique and Digital Quantification of the Loss of Enamel Volume

et al. 2020

The prevalence of white spots on teeth has increased in recent years. Regardless of their etiology, these lesions are characterized by a reduction in the enamel’s mineral phase, which is replaced by organic fluids. This causes an alteration of its chemical composition that affects its optical characteristics. Subsurface demineralization increases the pore volume of enamel, which in turn changes its optical refraction and results in the opaque color of white spot lesions. Here, we examined a non-invasive clinical technique used for eliminating these white spot lesions from enamel via two HCl-based products at different concentrations (6.6% and 15%). We used a digital method for evaluating the volumetric changes produced in dental enamel by the application of both products, one of which involved chemical erosion and the other, abrasive erosion. The mean volume of the enamel eliminated was −0.042 mm in 15% HCl, and −0.12 mm in 6.6% HCl. Thus, both 15% HCl and 6.6% HCl are capable of eroding the surface of the tooth enamel without reaching dentin. Moreover, 6.6% HCl produced a greater erosion of the dental enamel and left the surface a texture typical of an abrasive chemical-erosive product. The 15% HCl, however, produced an etching pattern typical of an erosive chemical with open enamel prisms prepared for subsequent adhesive procedures and restorers.
