Efficacy of CO lasers in preventing dental caries in partially erupted first permanent molars: a randomized 18-month clinical trial

AbstractThe aim of this controlled randomized double-blinded clinical trial was to evaluate the use of a CO2 laser with or without topical application of acidulated fluorides in the prevention of dental caries in partially erupted first permanent molars. We selected 61 healthy children at high risk of caries, all between 6 and 8 (7.1  ± 0.8) years of age and with 4 partially erupted first permanent molars. A CO2 laser device emitting at 10.6  μm was used (0.5 W, 0.05 mJ per pulse, 10 kHz). Each first molar in an individual was randomly assigned to one treatment: (L) CO2 laser (0.066  J/cm2); (FL) 1.23% acidulated fluoride gel and CO2 laser (0.066  J/cm2); (V) 5% fluoride varnish, or (S) sealant (control). Patients were followed-up at 3, 6, 12, and 18  months after treatment, through direct visual examination and by an operator blinded to the treatments (kappa ≥ 0.70). The International Caries Detection and Assessment System (ICDAS-II) index was used to assess the soundness of tooth structure or the presence of white spot lesions, cavitated enamel, and/or dentin lesions. The Yildiz Visual Index was used to evaluate sealant retention. Results were evaluated using Kaplan-Meier survival analysis, and the hazard ratio of the treatments was estimated using shared frailty models with a gamma distribution, which considered the patient as a cl uster. There were no significant differences among treatments compared to ...

Therefore, it is necessary to implement oral management strategies prior to the initiation of radiotherapy in patients with head ...

Grant, Harleen Kaur, Afrozul Haq, Mohammed S. RazzaqueAbstractAdequate nutrition is essential for maintaining good oral health. Minerals such as magnesium, calcium, and phosphorus found in the diet constitute the main structural components of the tooth. Their inadequacy leads to absorption impairment, increased bleeding tendency, bone resorption, looseness, and premature tooth loss. Inadequacy of those essential minerals is associated wi...

Authors: DENTAL SUPPLEMENT, Mummolo S, Sapio S, Falco A, Vittorini OL, Quinzi V Abstract The aim of this study is to evaluate the success of functional rehabilitation of one dental session in patients with severe disabilities such as severe autism, baby bottle syndrome and severe odontophobia, and to assess how patient compliance pre- and post-intervention changes in moderate sedation. Between the beginning of 2016 and the end of 2018, 20 pedodontic patients with severe odontophobia, severe autism and baby bottle syndrome who needed dental treatment came to our attention. Patients were aged between 3 and 12 years, ...

AbstractFluoride is an essential trace element for humans, and its deficiency or excess in the environment could lead to disease. To investigate the spatial distribution and health risk assessment of fluoride (F−) in drinking water, 302 tap water samples from Chongqing urban areas, China, were collected to analyze F− using an ion chromatograph. The results showed that (1) F− concentration in drinking water ranged from 0.100 to 0.503  mg/L, with an average of 0.238 ± 0.045 mg/L. (2) The spatial autocorrelation analysis showed that high–low clusters were mostly located i...

Abstract Environmental lead (Pb) exposure can induce dysbacteriosis, impair oral health, and is associated with the development of dental caries. However, the mechanism is unclear. The aim of this study was to explore the effects of Pb toxicity on oral antimicrobial activity in children in an e-waste area. Results showed higher blood Pb levels in e-waste-exposed group children, accompanied by decreased saliva SAG (salivary agglutinin) concentrations, increased peripheral WBC (white blood cell) counts and monocyte counts, and elevated peripheral monocyte percentage. LnPb (natural logarithmic transformation of blood...
