Abstract
INTRODUCION: The quality of dental restorations can be directly related to the maintenance of periodontal health. Particularly in relation to the contour of interproximal restorations, radiographs allow the assessment of possible excess or lack of proximal contact of restorative materials.OBJECTIVE: To evaluate the frequency of adequate and inadequate restorations, the type of restorative material and the relationship of these parameters with periodontal alterations.METHODS: One hundred digital panoramic radiographs were evaluated, with interproximal restorations being observed on these examinations, classifying them according to the material used and the quality of interproximal restoration and the presence of periodontal alterations. Thepossible correlation between these parameters was evaluated.RESULTS: The frequency of adequate restorations was 48% of restored proximal surfaces. Among the inadequate restorations, 46.2% and 53.8% were over-contour and lack of proximal contact, respectively. The restorations were metallic in 64% of cases.CONCLUSIONS: Over-contour were more common among metal restorations and lack of proximal contact was more frequent among non-metal restorations. The presence of restorations was associated with increased prevalence of periodontal alterations.
Highlights
The quality of dental restorations can be directly related to the maintenance of periodontal health
Untreated periodontal disease can compromise the success of restorative therapy and inadequate restoration can lead to an iatrogenic effect on periodontal tissues [1,2,3]
Periodontal alterations were present in 28% of cases
Summary
The quality of dental restorations can be directly related to the maintenance of periodontal health. In relation to the contour of interproximal restorations, radiographs allow the assessment of possible excess or lack of proximal contact of restorative materials. Dental restorations are intended to reestablish the form, function and aesthetics of the tooth. Restorative Dentistry has a close relationship with periodontal health. All restorative procedures should only be performed after examining clinical and radiographic periodontal structures. The technical quality of dental restorations is a crucial factor in maintaining the oral health [4,5,6,7,8,9]. The restorations with irregular contour are related to higher incidence of periodontal problems [8]
