SLY, Edith G; KAPLAN, Andrea E  and  MISSANA, Liliana. Clinical evaluation of glass ionomer for pit and fissure sealing of fully erupted molars. Acta odontol. latinoam. [online]. 2010, vol.23, n.1, pp.3-7. ISSN 1852-4834.

The aim of this study was to evaluate the clinical behavior of two conventional glass ionomers used for pit and fissure sealing in terms of retention, marginal adaptation, caries recurrence and cracking. Eighty-three fully erupted first permanent molars were sealed, in a group of children aged 5 to 8 years. A doubleblind, single operator, paired design was used. Materials applied were Fuji IX and VII. Retention (R), presence of caries (PC), marginal discoloration (MD), marginal adaptation (MA) and cracking (C) were evaluated at 6 and 12 months using Ryge’s criteria. Data registered 6 months after treatment were: Fuji IX: R: Alpha 37, Bravo 2, Charlie: 4; PC: Alpha 43, Bravo: 0; MA: Alpha 38, Bravo: 1; MD: Alpha 39, Bravo: 0, Charlie: 0; C: Alpha 39, Bravo: 0. Fuji VII: R: Alpha 29, Bravo 4, Charlie: 7; PC: Alpha 40, Bravo: 0; MA: Alpha: 34, Bravo: 0; MD: Alpha: 34, Bravo: 0; Charlie: 0; C: Alpha 33, Bravo: 0. Results after one year were: Fuji IX: R: Alpha 33, Bravo: 3, Charlie: 9; PC: Alpha 44, Bravo: 1; MA: Alpha 33, Bravo: 1; MD: Alpha: 34, Bravo: 0, Charlie: 0; C: Alpha: 34, Bravo: 0. Fuji VII: R: Alpha 22, Bravo 4, Charlie: 13, PC: Alpha 40, Bravo: 0; MA: Alpha 23, Bravo: 1; MD: Alpha 23, Bravo: 1, Charlie: 0; C: Alpha 23, Bravo: 1. Statistical analysis using Fisher test showed no significant difference (p>0.05) for R, and MA. For PC, MD and C, values are not reported because both materials showed the same results. The second control showed no significant difference (p>0.05) for R, MA, PC, MD and C. Results suggest no difference between Fuji IX and Fuji VII as sealants in fully erupted permanent molars.
