This study evaluated the effect of CO2laser irradiation and topical fluoride therapy in the control of caries progression on primary teeth enamel. 30 fragments (3×3×2 mm) from primary canines were submitted to an initial cariogenic challenge that consisted of immersion on demineralizing solution for 3 hours and remineralizing solution for 21 hours for 5 days. Fragments were randomly assigned into three groups (n=10): L: CO2laser (λ=10.6 μm), APF: 1.23% acidulated phosphate fluoride, and C: no treatment (control). CO2laser was applied with 0.5 W power and 0.44 J/cm2energy density. Fluoride application was performed with 0.1 g for 1 minute. Cariogenic challenge was conducted for 5 days following protocol previously described. Subsurface Knoop microhardness was measured at 30 μm from the edge. Obtained data were subjected to analysis the variance (ANOVA) and Duncan test with significance of 5%. It was found that the L group showed greater control of deciduous enamel demineralization and were similar to those of APF group, while being statistically different from C group (P≤0.05) that showed the lowest microhardness values. It was concluded that CO2laser can be an additional resource in caries control progression on primary teeth enamel.

Nas últimas décadas, um dos grandes avanços na Área da Saúde foi o desenvolvimento dos aparelhos de Laser, que possibilitou uma nova abordagem nos procedimentos odontológicos. A Laserterapia tem diversas aplicabilidades na Cariologia, seja como método de diagnóstico, como auxiliar nas medidas preventivas ou como tratamento da cárie dentária. Portanto, o objetivo desta revisão é proporcionar uma leitura atualizada da aplicabilidade da Laserterapia na Cariologia e, para tanto, foi realizada uma revisão literária sistematizada, na base de dados MEDLINE – Pubmed, abrangendo os últimos anos. Mediante esse estudo literário e considerando a evolução dos estudos científicos, ainda existem controvérsias a respeito da eficácia clínica do Laser na Cariologia.Descritores: Lasers; Cárie Dentária; Flúor.ReferênciasSichani AV, Javadinejad S, Ghafari R.

ABSTRACT Aim: The aim of this study was to evaluate the surface/mineral changes on enamel before and after the application of acidulated phosphate fluoride (APF) gel, fluoride enhanced hydroxyapatite gel and propolis in conjunction with carbon-dioxide (CO2) laser. Materials and Methods: Crowns of 40 human maxillary central incisors were collected and were divided into four groups of 10 each: Topical fluoride application only, topical fluoride application followed by CO2 laser irradiation, CO2 laser irradiation followed by topical fluoride application and CO2 laser irradiation before and after topical fluoride application. The 10 crowns in each group was again sectioned into four equal parts of mesio-incisal, disto-incisal, mesio-cervical and disto-cervical sections rendering 40 samples in each group. Each group was again subdivided into four subgroups: Subgroup C - untreated enamel surface (control). Subgroup A - APF gel application, subgroup R - fluoride enhanced hydroxyapatite gel application and subgroup P - propolis application. The surface morphology of the test samples were analyzed by scanning electron microscopy and mineral changes by energy dispersion X-ray spectrophotometer. Results: Total mineral content is maximum in Group 4A (CO2 laser irradiation before and after APF gel application) and calcium/phosphate ratio is highest in Group 4R (CO2 laser irradiation before and after Remin-Pro application). Group 2A (APF gel application followed by CO2 laser irradiation) has the maximum fluoride retention. Conclusion: Laser irradiation of enamel through a topically applied APF gel is effective in the prophylaxis and management of dental caries.
