Objectives: This study evaluated the effects of radiotherapy on the composition of deciduous teeth enamel using micro-energy-dispersive X-ray fluorescence and Fourier transform Raman spectroscopy before and after a pH cycling process.

Materials And Methods: Ten deciduous molars were sectioned and divided into two groups (n = 10). The radiotherapy group (RT) was irradiated with 54 Gy at 2 Gy/day, 5 days per week for 5 weeks and 2 days, and the normal group (N) was not irradiated.

Objective: The present study aims to investigate the effect of a low-power infrared laser on the inhibition of bovine enamel demineralization around orthodontic brackets.

Background Data: Near infrared lasers have been suggested as alternative approaches because they may produce an increase in resistance to dental caries.

Methods: Forty-eight blocks of enamel obtained from bovine incisor teeth were divided into six groups: Group 1 (control), without treatment; Group 2 (C), photoabsorbing cream; Group 3 (CF), photoabsorbing cream with fluoride; Group 4 (L), irradiation with low-level infrared laser (λ=830 nm) at an energy density of 4.

Conservation of deciduous teeth with pulp alterations caused by caries and trauma is a major therapeutic challenge in pediatric dentistry as a result of the internal anatomy and life cycle characteristic. It is essential that the root canal procedures sanitizers have a performance in eliminating bacterial. In this context, antimicrobial photodynamic therapy (PAT) is promising and emerging as adjuvant therapy in an attempt to eliminate the microorganisms persistent to chemi-mechanical preparation.

Objective: The aim of this study was to assess the effect of low-intensity infrared laser light (λ=810 nm, 100 mW/cm(2), 90 sec, 4.47 J/cm(2), 9 J) with or without indocyanine green cream fluorinated or not fluorinated, using Knoop surface microhardness analysis.

Background Data: Lasers can be used as tools for the prevention of tooth enamel demineralization.

Aim: This study aimed to describe certain common oral manifestations during early childhood that should be known by the pediatric dental surgeon.

Background: The correct diagnosis and treatment of oral manifestations during early childhood is important for children's development. The pediatric dentist is responsible for maintaining oral health in children, since they change constantly during their development and growth.
