Eligibility

Age
18 Years to No maximum

Inclusion criteria

Inclusion criteria: Patients over 18 years of age of either gender; available for follow-up visits; having at least 2 molars with deep caries lesions no larger than 4 mm or unsatisfactory restorations characterized by: marginal misfit, under-filling, secondary caries, or amalgam; the teeth to be restored must show a positive response to a cold test using gas cooled to -20°C, Aerojet; absence of spontaneous pain; negative sensitivity to percussion; and absence of periapical lesions on radiographic examination

Exclusion criteria

Exclusion criteria: Patients with parafunctional habits; systemic disease; pregnant or breastfeeding women; teeth with pulp involvement or that have undergone endodontic treatment; patients currently undergoing orthodontic treatment or planning to begin treatment; teeth with periodontal disease; teeth to be restored that lack an opposing tooth; patients will be excluded if they have cusp loss; caries below the gingival margin; or non-carious cervical lesions

Design outcomes

Primary

MeasureTime frame
It is hoped that the findings of this study will contribute to a better understanding of the various photoactivation protocols and their impact on the clinical longevity of posterior tooth restorations in Class I cavities, as measured by the presence of fractures, chipping, detachment, secondary caries, and marginal integrity.

Secondary

MeasureTime frame
No secondary outcomes are expected
