White spots on tooth enamel in mixed dentition

Aim: To determine the prevalence, etiological factors of white spots on enamel and to evaluate the treatment by microabrasion technique in schoolchildren. Method: A study was developed in children between the ages of 6 and 12 of both genders, enrolled in 3 municipal public schools. Oral examination of the children was carried out, and for those children in whom white spot lesions were found, dental treatment was provided by the microabrasion technique in the incisors and/ or first permanent molars to prevent the evolution to a caries lesion with cavitation, since the enamel structure was damaged. Results: The most affected age was 10 years with 27.8% (n = 5). In relation to the enamel surface area affected by white patches, the majority had 1% - 24% of the enamel reached. The possible etiological factors of white patches were systemic infections, trauma or caries with pulp involvement in a deciduous tooth. The treatment was effective in 16 children and for the remaining two the restorative treatment was performed. Conclusion: The prevalence of white spot lesions found in enamel was 3.95%, with a higher prevalence in females. The permanent right upper central incisor was the most affected. The treatment proved to be effective in most children possibly because the lesion is located more superficially in the enamel.KeywordsDental enamel; Enamel hypoplasia; Tooth demineralization; Enamel microabrasion.

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.

The Impact

Abstract Aim of the study: This study evaluated the impact of two remineralizing agents containing casein phosphopeptideamorphous calcium phosphate (CPPACP), and Tricalcium phosphate (TCP) on white spot lesions. Materials and Methods: A total of ninety freshly extracted upper premolars were divided in three equal groups (30 each). Group A: Control group. Group B: Varnish containing CPP–ACP. Group C: Varnish containing TCP. The teeth were subjected to Diagnodent test after inducing white spot lesions to assess any surface changes present on the teeth. The readings were repeated post demineralization and post-remineralization. Results: Statistically significant difference was present in the mean values between the tested groups. CPP-ACP group recorded higher mean value at demineralization when compared to TCP group. Statistically significant difference (p < 0.0001) was present between the baseline and the demineralization values. CPP-ACP group presented higher remineralization results when compared to TCP group. T-test proved a significant difference between the tested groups. Conclusion: CPP-ACP containing varnish had higher remineralizing effect when compared to TCP containing varnish. Clinical Significance: Recently, the focus of restorative dentistry has been directed toward a conservative approach. Prevention and non-restorative treatment of initial enamel caries is the main concern. Remineralization procedures are the most preferred way of regeneration of lost tooth structure.

Abstract Early diagnosis of white spot lesions allows non-invasive treatment to be indicated for the remineralization of active lesions. The goal was to report the clinical Protocol for the treatment of white spot lesion of a patient by the technique of resin infiltration, observing whether there is change of color on the white spot of the dental enamel after its treatment. The selected patient was 16 years old with good overall health, who featured white spot lesion of the dental enamel on tooth 13, classified as ICDAS score 2. The tooth was photographed, and its color was evaluated with the spectrophotometer in accordance with the CIELhC system. For comparison purposes, the color of tooth enamel in an area adjacent to the lesion was evaluated. The treatment of the lesion was performed with the resin infiltrate Icon (DMG, Hamburg, Germany), following the manufacturer's instructions. The color of the tooth was re-evaluated after the application of the resin infiltrate. At the end of the procedure, it was observed that the treatment of white spot lesion by resin infiltration technique reached its goal because, in addition to being minimally invasive, it was highly approved by patient and it provided the masking of the white spot lesion on the dental enamel.

Demineralization is a common problem following orthodontic treatments. Today using antibacterial nanoparticles in preventing white spot lesions is being discussed. Given that ZnO and TiO2 nanoparticles have direct antibacterial known properties, this study aims to evaluate these nanoparticles' antibacterial effects in orthodontic bondings' composition on preventing white spot lesions. In this in vitro experimental study, 43 sound human premolar teeth were divided into five groups according to the adhesive utilized for bracket bonding: None group consisting of 12 teeth bonded with Transbond XT, TiO2 Group consisting of 12 teeth with Transbond XT and TiO2 nanoparticles, ZnO group consisting of 12 teeth with Transbond XT and ZnO nanoparticles, a positive control group consisting of 5 teeth without brackets and negative control groups consisting of 5 teeth in a sterile medium. All teeth were stored in a medium consisting of 1cc brain heart infusion (BHI) + sucrose 1%+ 0.5 McFarland Streptococcus mutans bacteria for 28 days. The medium was replaced every 48 hours. All the samples were examined every week for 4 weeks using DIAGNOdent and photography to detect white spots. The results of this study revealed that adding TiO2 and ZnO nanoparticles to Transbond XT bonding caused a decrease in enamel lesions occurrence and incidence of white spots (p value= 0.00). The results did not reveal significant differences between TiO2 and ZnO groups. Novel bonding agents containing TiO2 and ZnO nanoparticles represent promising candidates in combating enamel white spot lesions.

Objective: To determine the incidence of dental caries in 64 leukemic children who received dental treatment before the initiation of chemotherapy and had intensive oral care during the course. Design: Caries experience (deft/DMFT), white-spot lesions (enamel demineralization), premature primary molar extractions and carious first permanent molars were investigated before and after intensive therapy. Setting: Pediatric Dental Care Unit and Department of Pediatric Hematology, Faculty of Medicine, Uludağ University. Results: The dental caries level was insignificantly higher following chemotherapy compared to the initial caries level. However, the prevalence of white-spot lesions was significantly increased during the course. Caries level in 30 subjects (47%) remained stable. Conclusion: Caries level in leukemic children, who were not caries-free before chemotherapy, could be stabilized by caries prevention methods such as frequent topical fluoride applications and fissure sealants, intensive oral care and improved self-care practices.

Orthodontic treatment success is jeopardized by the risk of development of white spot lesions (WSLs) around orthodontic brackets. Unfortunately, the formation of WSLs still remains a common complication during treatment in patients with poor oral hygiene. Nearly 75% of orthodontic patients are reported to develop enamel decalcification because of prolonged plaque retention around brackets. It is the orthodontist’s responsibility to minimize the risk of patients having enamel decalcifications as a consequence of orthodontic treatment. This can be achieved by using hybrid, fluoride-releasing, glass ionomer cement to bond brackets, with deproteinization of the enamel surface before phosphoric acid etching.
