Introduction. Postoperative sensitivity in restorative dentistry can be
related to preparation trauma, dentin adhesives’ ability to seal open
dentinal tubules, deformation of restorations under occlusal stresses and
microleakage. Objective. The study assessed possible reduction in
postoperative sensitivity with low shrinkage compared to conventional
composites using different bonding agents and the influence of the operator
skill on the incidence of postoperative sensitivity. Methods. Nine hundred
and sixty permanent premolars and molars with primary carious lesions from
patients 21 to 40 years old were used. Cavities 2 to 3 mm deep and with
margins in enamel were prepared by four operators. Two operators had five
years (A and B) and two had over 20 years (C and D) of clinical experience.
Teeth were divided into eight groups each contained 120 restorations: (1)
Els®+James-2 (original formula), (2) Els®+James-2 (new formula), (3)
Els®+Excite, (4) InTenSe®+James-2 (original formula), (5) InTenSe®+James-2
(new formula), (6) InTenSe®+Excite, (7) Tetric Ceram®+Excite, and (8) Point
4®+OptiBond Solo Plus. At 14 days postoperatively, two independent operators,
who did not take part in the clinical procedure, assessed postoperative teeth
sensitivity using special questionnaires. Data were analyzed using
non-parametric chi-square, Mann-Whitney and ANOVA tests. Results. Group 8
showed significantly higher score than the other groups. Less postoperative
sensitivity was reported with two low-shrinkage composites (groups 2, 3, and
5) but with no significant difference. There was no statistical difference
between groups 1, 2, 3, 4, 5, 6 and 7. Operator A had the highest
postoperative sensitivity score compared to the other three. Conclusion.
Conventional composite material Point 4® with its bonding agent caused
significantly more postoperative sensitivity than low shrinkage composites
combined with different adhesives. Operator skill influenced the incidence of
postoperative sensitivity.
