NCT02561689

Brief Summary

Background: Occlusal caries is the main reason for restorative therapy in the young permanent dentition, but restorations have limited survival time and may also weaken the tooth. An intact fissure sealing is an effective preventive treatment of occlusal caries lesions and may be used therapeutically to arrest the caries progression. However, the major challenge with fissure sealants is the frequent need for re-treatments, mostly due to inadequate retention. Purpose: To quantify the longevity and effectiveness of the 6 resin sealants used prophylactically and therapeutically in permanent molar teeth. Study design: The study is carried out as a prospective, clinically controlled study with split-mouth design, where each of the 60 dentists/dental hygienists from 13 municipalities in Denmark uses 2 of the 6 sealants. The treatments are examined clinically and radiologically after 1, 2, 3, and 5 years.

Outcome Measures

Primary Outcomes (2)

  • Longevity of 6 resin fissure sealants assessed by defined scoring system

    Clinical scoring system: 1: Intact sealing (success), 2: Partly loss of sealant (failure); 3: Total loss of sealant (failure)

    5 years

  • Efficacy of 6 resin fissure sealants assessed by defined radiological scoring system

    Radiographic scoring system: 1:Regression in depth of lesion (success), 2: Unchanged depth of lesion (success); 3: Progression in depth of lesion (failure)

    5 years

Interventions

Procedure: * The included teeth of the participating patients will in any case be sealed, but in this study, the operator is not free to choose the material, the material choice is determined by randomisation * Standardized radiographs (bitewings) will be taken before treatment and after 1, 2, 3 years and possibly after 5 years. Baseline radiograph can be taken up to six months before treatment. If using conventional radiography, double-film packs will be used. A maximum of 8/10 bitewings will be taken during the study period of 3/5 years * The occlusal surface is sealed by the dentist or dental hygienist. * Clinical evaluation of the quality of sealants and the need for re-treatments during the follow-up will be performed after 1, 2 and 3 years and possibly after 5 years

Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Children and adolescents 5-14 years of age
  • Children with 2, 4, 6 or 8 molars assessed to be in need of prophylactic or therapeutic sealing
  • The radiographic penetration of the occlusal caries lesion must be limited halfway through the dentin

You may not qualify if:

  • In case the occlusal surface is restored with communication between the restoration and the included lesion
  • Subjects with chronic diseases that could affect their caries pattern
  • Pain in teeth
