Title: ART and Hall Technique for the Management of Occlusal-proximal Caries in Primary Molars: A Randomized Clinical Trial
Brief Summary: The aim of this, two-arm, parallel group, patient-randomised controlled, superiority trial is to evaluate the survival rate of approximal Atraumatic Restorative Treatment (ART) restorations compared to the Hall Technique (HT) placed in a school setting. The investigators will recruit 120 schoolchildren (5-10 years) with at least one occlusal-proximal carious lesion in primary molar. They will be randomized and treated following best-practice protocols to either receive an ART restoration using the high-viscosity glass ionomer cement (EQUIA Forte, capsules, GC Corp.) or a preformed metal crown placed using the HT (3M ESPE) cemented with glass ionomer luting cement (Fuji I Capsules, GC Corp.). Baseline measures and outcome data (at reviews over a three year period) will be assessed through participant report, clinical examination and parent report/ questionnaires.


Options:
A: Inclusion Criteria:

* Subjects were to have at least three caries proximal lesions on their posterior permanent teeth with a radiographic severity classification of the lesion score of 3 -Around the enamel dentin junction (EDJ) or 4 -Dentin-outer 1/3.

Exclusion Criteria:

* Under orthodontic treatment at enrollment
* Moving from the city (Bogota) in the following three years after commencing the study.
B: Inclusion Criteria:

* Person ≥ 18 yrs having deep caries with or without pain:
* x-ray show primary caries in the inner 1/4 of the dentin, with the presence of a radiopaque zone at the pulpal wall NB: Need to mark a 'yes' for both criteria!

Exclusion Criteria:

* Deep carious tooth with (irreversible pulpitis)unbearable pain and/or disturbed night's sleep)
* Deep carious tooth negatively responding on thermal and electrometric tests.
* Deep carious tooth has 'attachment loss' \> 5 mm
* X-ray shows apical radiolucency of the actual tooth
* Deep carious tooth has restoration in direct contact with the pulp
* The person has problems with communication
* No informed and written consent is present
* Due to health conditions or pregnancy the person can not participate in the trial

NB: Need to mark 'No' for all criteria
C: Inclusion Criteria:

* children aged between 5 and 10 years
* cooperative behavior
* presenting good health conditions
* whose parents or legal guardians accept and sign the consent form
* with at least one occluso-proximal lesion in primary molar
* only occlusal-proximal surfaces with caries lesions with dentin involvement
* cavities accessible to hand instruments used in ART
* absence of fistula or abscess near the selected tooth
* absence of pulp exposure in the selected tooth
* absence of mobility in the selected tooth
* cavity size in the selected tooth not be bigger than 2.0 mm in the mesial-distal and 2.5 in the occlusal-cervical and bucco-lingual directions.

Exclusion Criteria:

* children younger than 5 years and older than 10
* non-cooperative behavior

* cavity size bigger than 2.0 mm in the mesial-distal and 2.5 in the occlusal-cervical and - bucco-lingual directions.
D: Inclusion Criteria:

* Early occlusal carious lesions (without cavity) on permanent molar "6" or "7" at eruption which does not require an invasive treatment
* Age ≥ 5 years
* Size and form of the lesions: the lesions must both be fully visible and assessable and accessible
* Willing and able to attend the on-study visits and to observe good oral hygiene throughout the study
* Written informed consent before participation in the study

Exclusion Criteria:

* Evidence of tooth erosion
* Fluoride varnish application \< 3 months prior to study treatment
