“…In our study, it was noted the presence of taurodontia in only 7.9% of cases, where it presented with a predominance in the mandible. Although this anomaly is related mainly as a marker of orofacial anomalies, it was noted that even in a normal population it can be a complication mainly for endodontic treatment, due the taurodontia was decreased the root surface area and for prosthetic treatments that require an adequate occlusal load 15,16 .…”

Panoramic radiographs are complementary exams to evaluate oral alterations in an early manner, these changes can be dental developmental anomalies, and post-eruption dental disorder. Aim: This study evaluated the findings in panoramic radiographs and correlated the variables of gender and dental location. Methods: A retrospective study was through the observation of 1.111 panoramic radiographs from the Radiology Department in Brazil. It was included patients from 5 to 79 years of age of both gender, and it classified the anomalies in shape, size, and number and post-eruption dental changes in and correlated with gender and location. Patients with syndromes were excluded from the sample. Results: The majority of the sample was composed of fameles 752 (67.7%), as to the frequency of dental developmental anomalies related lesions 684 cases (61.6%) and post-eruption dental disorder 567 (51.8%), in the radiographs. The most prevalent change was endodontic treatment (32.6%), followed by root dilaceration (25.9%), and included tooth (19.5%). The most prevailing alteration when correlated with the gender variables was the cyst root (p<0.01) in females, and orthodontic treatment (p=0.02) in males and the variable location in the mandible was root dilaceration, giroversion, impacted tooth, taurodontia, microdontia, and endodontic treatment (p<0.01). Conclusion: Our findings provide evidence that dental developmental anomalies e post-eruption dental disorder are frequent alterations in the population with particular characteristics of distribution by sex and location.

“…Nesse tipo de exame, os pré-molares e molares inferiores são bem visualizados, com pouca distorção, daí a escolha em estudar esses elementos dentários. Weckwert et.al 2016 18 também analisaram a dilaceração radicular em indivíduos com fissuras labiopalatinas através de radiografias panorâmicas e salientaram que este tipo de exame é uma boa opção na visualização da curvatura radicular.…”

“…Na literatura existem várias definições sobre a dilaceração radicular, porém não há um consenso quanto a sua classificação. A dilaceração é considerada quando há uma curvatura anormal da raiz22, que pode ser a partir de um ângulo >90°1 2,13,16,18 ou >20°1 4 . Os autores em sua maioria não descrevem um método para o diagnóstico da dilaceração radicular, apenas classificam quando um elemento dental apresenta uma curvatura acentuada em relação ao seu longo eixo.…”

Fissuras labiais e/ou palatinas não sindrômicas (FL/PNS) representam a anomalia congênita mais comum em humanos. Entretanto, são poucos os estudos que analisam a curvatura e dilaceração em pacientes acometidos pela FL/PNS. O objetivo deste estudo foi avaliar a prevalência de dilaceração radicular em 400 indivíduos portadores de FL/PNS, assim como relacionar o grau de curvatura da raiz com os diferentes tipos de fissuras. Observou-se que raízes de pré-molares e molares apresentaram diferentes direções (p<0,001). Raízes retas e inclinadas para a face distal foram mais prevalentes (46,6% e 44,5% respectivamente). Existem diferenças quanto a localização da curvatura em relação ao 1/3 radicular (p<0,001). As fissuras labiais e as fissuras palatinas apresentaram maior frequência de dilaceração radicular. Não foi observado associação significativa do grau de curvatura radicular dos molares e pré-molares a um tipo específico de fissura. Esses resultados sugerem a realização de estudo caso-controle para que questões relativas às diferenças de angulação entre os portadores de FL/PNS e a população em geral, sejam respondidas.

“…It is well accepted that both genetics and environmental factors play a role in the development of cleft lip and palate (Vieira 2012). A higher frequency of dental abnormalities has been reported in patients with cleft lip and/or palate than in the general population (Al Jamal et al 2010;Letra et al 2007;Paranaiba et al 2013;Weckwerth et al 2016); among them are dental agenesis, supernumerary teeth, microdontia, taurodontism, root laceration, fused teeth, ectopic eruption, and enamel hypoplasia (Letra et al 2007;Melo Filho et al 2015;Paranaiba et al 2013).…”

“…The enlargement of the pulp chamber with a consequent apical displacement of the pulpal floor in multirooted teeth is a phenomenon that is generally identified radiologically, not clinically, and affects many types of dental therapies: complicates endodontic treatments and reduces the root surface area available for anchoring in orthodontics or adequate resistance to occlusal load for pontics (MacDonald 2020). This anomaly has been investigated in patients with cleft lip and palate in which, from a panoramic radiograph, it can be diagnosed, and its classification is based on the extension of the enlargement (Weckwerth et al 2016). However, there is no consensus in the literature regarding the methodology to classify taurodontism; therefore, we believe that using the term pulp enlargement to define those with this condition is more appropriate.…”
