Evaluating the Number of Walls Present and Its Significance on the Teeth Restored with Prefabricated Fibre Post in Maxillary Molars
Introduction: Endodontic ultimate goal is to keep a tooth alive for as long as feasible for the patient. Posts, whether prefabricated metal posts, cast posts, or fibre posts, are used to restore many teeth. Although fibre posts are currently the greatest alternative, prefabricated metal posts have proven to be the most popular. Depending on how each circumstance presents it, the various solutions provide additional flexibility. Posts can help strengthen the relationship between the coronal building material and the remaining tooth structure by retaining amalgam, metal, and composite cores. The aim of the study is to evaluate the number of walls present and its significance on the teeth restored with prefabricated fibre posts in maxillary molars. Materials and method: In this retrospective study, the data was collected from the hospital database and further analysis was done and the results were tabulated. A statistical analysis of the collected data regarding the variance among the different number of residual walls seen in maxillary molars undergoing prefabricated fiber post treatment. Results: The study sample consisted of 14 patients who underwent prefabricated fibre posts treatment in maxillary molars. 28.57% were performed in right maxillary permanent first molar, 21.43% were performed in right maxillary permanent second molar, 7.14% were performed in right maxillary permanent third molar, 28.57% were performed in left maxillary permanent first molar, and 14.29% were performed in left maxillary permanent second molar. 7.14% of the patients had only 1 wall, 78.57% of the patients had 2 walls and 14.29% of the patients had 3 walls. The association between the tooth number and number of walls present was not found to be statistically significant (p value= 0.219). Discussion: In the present study, 2 walls based prefabricated fibre posts were more prevalent. It can be inferred that prefabricated fibre posts are more commonly indicated in maxillary molars with some solid amount of vital tooth structure. Previous studies have not correlated the significance between number of walls present and the use of prefabricated fibre posts in maxillary molars. Previous study conducted by Nam et al had concluded that in terms of fracture resistance and stress distribution, the FRC post was beneficial in lower premolars, especially with two or more walls. Conclusion: Within the limitations of the study, it can be concluded the remaining coronal walls influence the type of post selected for the restoring endodontically treated teeth. The prevalence of prefabricated fiber posts in maxillary molars was most commonly seen in teeth with 2 residual walls. Fiber reinforced posts are the most preferred post in posterior teeth, due to its flexural strength matching the dentin and its better distribution of stress among the remaining tooth structure.
