Abstract:

Objectives: To evaluate after 2 years, the survival rate of glass ionomer cement (GIC)
sealants placed in primary molars of 6-8 year-olds and as part of proximal ART
restoration.
Study design: A longitudinal clinical study.
Setting: Matungulu/Kangundo rural divisions, Machakos district.
Participants: A total of 804 six to eight year-olds from rural Kenya received sealants as
part of proximal restorations placed in primary molars using the atraumatic restorative
treatment (ART) approach. Trained operators, using the ART approach, placed the
proximal restorations and the sealants using Fuji IX, Ketac Molar Easymix and Ketac
Molar Aplicap, together with rubber dam and cotton roll tooth-isolation methods.
Evaluation to determine the survival of the sealants was done soon after placement
(within 2 hours of placing them) and after 2 years. The data were analyzed using SPSS
14.0 computer programme, and the survival results related to the materials and the
isolation-methods used.
Results: The 2-year cumulative survival of the sealants was 10.9%, and the survival of
the sealants was not significantly affected by the GIC material brand and the toothisolation method used. However, slightly more sealants survived when Fuji IX and rubber dam tooth-isolation method were used.
Conclusion: The two-year survival rate of the sealants was poor and was not
significantly influenced by the GIC material or the tooth-isolation method used.
