Treatment Decision-making of Cracked Teeth: Survey of American Endodontists

Abstract

Aim:The aim of this study is to survey the opinion of endodontists in the United States regarding their approach to treatment of cracked teeth. Materials and methods: A survey assessing the opinions of 3,500 endodontists in the United States was administered over a 4-week period. It consisted of a hypothetical clinical case and eight different treatment scenarios. Participants were asked to select one of the two treatment options: (A) informing the patient of the presence of a crack, reinforcing the tooth, and continuing with endodontic treatment; and (B) extraction of the tooth followed by replacement with an implant supported crown or fixed partial denture. Results: When the crack extended across the distal marginal ridge with no associated probing depths, 92.65% endodontists preferred to continue with endodontic treatment and reenforcing the tooth. When the crack extended across the distal marginal ridge and was associated with a probing depth of 6 mm, 80% preferred extraction of the tooth. When the crack extended across the mesial marginal ridge up to the orifice of the mesiolingual canal with no associated probing depth, 82.78% preferred to continue with the treatment. When the crack was associated with a 6-mm probing depth, 83.79% preferred tooth extraction. When the crack extended across the mesial marginal ridge and down into the mesiolingual canal with/without associated probing depth, 91.13% and 63.54% preferred tooth extraction, respectively. When the crack involved both mesial and distal marginal ridges and extended across the pulp chamber, 79.74% preferred tooth extraction. When a split tooth was presented, 98.48% preferred tooth extraction.Conclusion: It appears that the presence of a 6-mm periodontal pocket is considered an important factor by most American endodontists when deciding whether to preserve the cracked tooth or extract it. Clinical significance: There is no consensus among dentists regarding the best approach to treat cracked teeth. Conclusive studies evaluating clinical approaches of endodontists regarding treatment of cracked teeth are lacking. Therefore, surveyed opinion of endodontists in the United States regarding their approach to treatment of cracked teeth was done to try to reach the best clinical decision regarding this dilemma.

Análise em micro-CT de dente rachado em segundo molar mandibular com anatomia em C após trauma oclusal: Relato de caso

“…Em uma pesquisa recente com 3.500 endodontistas nos Estados Unidos, a presença de uma bolsa periodontal de 6 mm de profundidade associada resultou em ser o fator mais crucial na decisão de tratar ou extrair um dente rachado com envolvimento pulpar. (Abulhamael, et al, 2019). O diagnóstico precoce e preciso da fissura dentária ainda é um desafio na prática clínica.…”
