Brief Summary

Background: The traditional approach of carious lesions with risk for progression has has been to excavate all infected and demineralised tissue before placement of the restoration. In primary teeth, treatment of deep carious lesions is associated with significant risk of pulp lesions and postoperative complications and thus the risk of the teeth being lost. During the past decade, more focus has been on biological methods for caries excavating of deep dentin lesions. An overview comparing different biological methods such as partial or stepwise excavation of deep dentin caries in primary teeth shows that they work as well as traditional methods performing complete caries excavation but have the benefits of reducing the risk of iatrogenic pulp damage \[1-3\]. Our primary hypothesis is that there is no difference in tooth or filling survival after partial caries excavation compared to complete caries excavation in primary molars. The secondary hypothesis is that the therapist's knowledge, experience and treatment attitudes and choices are not affected by a participation in the study.

Outcome Measures

Primary Outcomes (2)

  • Success

    Success will be measured by assessing if the restoration is in place (i.e. tooth in place vs. tooth lost) and without comment.

    24 months

  • Tooth survival

    Tooth survival will be measured by assessing tooth exfoliation without causing pain or infection.

    24 months

Secondary Outcomes (1)

  • Decision-making Questionnaire

    24 months

Study Arms (2)

Partial excavation

EXPERIMENTAL

The treatment will be performed after applying local anesthetic according to individual needs. The intervention group will receive partial removal of the carious lesion; In the inner part of the lesion, the caries removal will be limited to reach leathery or slightly soft dentin by probing. The restorations will be placed according to evidence based methods and the material used according to the operators material of choice.

Procedure: Partial excavation

Complete excavation

ACTIVE COMPARATOR

The treatment will be performed after applying local anesthetic according to individual needs. The control group will receive the same treatment procedure as the intervention group, but the excavation procedure will include total removal of the carious tissue. The total caries removal will be ensured with hardness on probing and the visual examination. Photographs will be used as benchmark.

Procedure: Partial excavation

Interventions

Operators sign up for participation at the homepage of Center for Pediatric Oral Health Research (ABC). The study will be carried out in a Practice-Based Research Network setting. All practitioners interested in participating in the study will get access to an online information about their participation after they signed up. The participation starts by answering a questionnaire on their treatment attitudes and experiences. Patients will be identified during the routine dental examination. If a carious lesion in the primary molars is detected and in a need of a restoration, the children and parents will be asked to participate in the study. The parents receive information about the study and give their consent. Allocation into treatment groups will be performed by random assignment by the homepage of ABC. After the study is finished the participating dentist will be asked to answer the same questionnaire to investigate the effect of the participation on the operators attitude.

Eligibility Criteria

Age3 Years - 8 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Children in the age of 3-8 years, with one or more primary molar teeth in a need of a restoration due to a moderate depth of carious lesion;
  • caries lesion diagnosed into dentin on radiographs though not exceeding the inner third of the dentin
  • caries lesion diagnosed visually with a cavity into dentin.

You may not qualify if:

  • Children with behaviour management problems.
  • Teeth with pulpal symptoms
