Prevalence of defective restorations and factors associated with re‐intervention in primary teeth: A retrospective university‐based study

Abstract

Aim This retrospective study investigated the prevalence of defective restorations in a public dental service and factors associated with re‐intervention in primary teeth. Design The sample consisted of all clinical records (census) of children presenting restorations in primary teeth, who had undergone dental treatment in a public set during 1‐year period. For analysis, only restorations presenting defects related to esthetic, functional, or biological reasons at first clinical examination were included. The outcome ‘Success’ was set when the restoration received no treatment (monitored), refurbishing, sealing of margins, or was repaired. Otherwise, ‘Failure’ was set whenever the restoration was either replaced or if another treatment affecting the restoration was necessary (endodontic treatment or tooth extraction). Poisson regression model was used to assess the prevalence of patient‐ and tooth‐related factors that may influence the re‐intervention decision (repair or replacement). Results From a total of 302 restorations placed in 114 children, 37.7% presented some type of defect. Restorations with recurrent caries were more frequently present in caries‐active patients (P = 0.03) and were frequently replaced (95% CI, 1.05‐3.22, RR = 1.84, P = 0.03). Conclusion Presence of recurrent caries influences the re‐intervention decision, leading to restoration replacement in most cases.

Repair of defective resin composite restorations in primary teeth: current trends in Brazilian undergraduate Dental programs

“…The diagnosis of recurrent caries is the main reason for restoration replacement 15 . It has been shown that the presence of recurrent caries influences the decision to intervene, and this leads to restoration replacement in most cases 16 . Although recurrent caries are histologically similar to primary caries, the clinical diagnosis for evaluating the presence of caries or staining around restoration margins is a challenge for dentists and it is a subjective process.…”

Effect of Polyols and Selected Dental Materials on the Ability to Create a Cariogenic Biofilm–On Children Caries-Associated Streptococcus Mutans Isolates

“…This phenomenon affects the development of the carious process in the surrounding hard tissues, both enamel and dentin, which in turn increases the risk of complications from the pulp and then leads to the need to replace the filling [1,2]. Replacement of the filling is associated with the necessity to widen the removed margins of the tooth tissue, which can then lead to further cycles of intervention and is associated with increased treatment costs [3]. Etiopathogenesis of secondary caries does not differ from primary caries and depends mainly on host-related factors such as diet and oral hygiene [4].…”

“…These substances are naturally found in many fruits and are manufactured from natural raw materials, such as lignocellulosic biomass (xylitol), starch (sorbitol), and glucose (erythritol) [14,15]. In vitro, in vivo, and clinical studies have consistently demonstrated the safety of these substances [1][2][3][4], which has been confirmed by recommendations issued by the WHO/FAO (World Health Organization/Food and Agriculture Organization of the United Nations) Joint Committee of Experts on Food Safety in over 60 countries around the world [16].…”
