Exclusion criteria:

• Children who are considered medically compromised or medically complex patients. The absence of disease is confirmed by anamnestic interview with a parent or a care-giver of the child and excludes general acute or chronic disease, cognitive impairment, psychogenic nonepileptic events, radiotherapy in the maxillofacial region due to malignant process.
• Patients who are undergoing therapy with neurological, sedative, analgesic and/or anti-inflammatory drugs 7 days prior to treatment.

Included are carious lesions only on vital teeth, involving up to half of the dentine thickness, with no periodontal pathology. Laser fluorescence diagnosis of adjacent lesions with DIAGNODENT is limited to 20 - 35 scores included.
• Included are first molars which are not affected by hypoplasia or hypomineralization.
