Resumo
Nódulos pulpares são calcificações presentes na câmara pulpar, aderidos nas paredes dentinárias ou como nódulos soltos e podem bloquear parcialmente ou totalmente o acesso aos orifícios dos canais radiculares. Devido à limitação de estudos realizados anteriormente com radiografias, o objetivo desse trabalho foi determinar a prevalência de nódulos pulpares por meio da tomografia computadorizada de feixe cônico (TCFC) e explorar qualquer correlação potencial entre a ocorrência de nódulos pulpares com gênero, idade, dente, arcada e estado da coroa dentária. Para isso foram utilizadas TCFC de 300 pacientes, totalizando 631 molares. Todos os molares foram analisados nos planos sagital, axial e coronal e, quando presentes, os nódulos pulpares foram identificados como uma massa redonda ou oval hiperdensa. Após tabulação dos dados, a análise estatística foi realizada através da aplicação de testes de qui-quadrado. De um total de 300 pacientes, os nódulos pulpares foram identificados em 35% e em 25.5% dos 631 molares analisados. A presença dos nódulos pulpares foi mais frequente no sexo feminino (41.1%) do que no masculino (27.7%) e nos indivíduos com idade acima de 80 anos. Os primeiros molares superiores exibiram a maior incidência de nódulos pulpares. Nenhuma diferença significativa foi observada quando os arcos maxilar e mandibular e os lados foram comparados. A presença de nódulos pulpares foi elevada em molares restaurados quando comparados aos dentes íntegros (P <0,05). A Tomografia Computadorizada de Feixe Cônico é um recurso eficiente para o diagnóstico e localização dos nódulos pulpares.
Pulp stones are calcifications present in the pulp chamber adhered to dentin walls or as loose nodules and can partially or totally block access to root canals entrance. Due to radiographic limitation of previous reports, the objective of this study was to determine the prevalence of pulp stones by cone beam computerized tomography (CBCT) and to explore any potential correlation between the occurrence of pulp stones with gender, age, tooth, arches and condition of the dental crown. CBCT of 300 patients were assessed, totaling 631 molars. All molars were analyzed in the sagittal, axial and coronal planes and, when present, pulp stones were identified as a round or oval hyperdense mass. After data tabulation, statistical analysis was performed using chi-square tests. Of a total of 300 patients, pulp stones were identified in 35% and in 25.5% of the 631 analyzed molars. The presence of pulp stones was most frequently found in females (41.1%) than in males (27.7%) and in individuals aged over 80 years. The first upper molars showed the highest incidence of pulp stones. No significant difference was observed when maxillary and mandibular arches were compared neither sides. The presence of pulp stones was higher in restored molars when compared to intact teeth (P <0.05). Cone Beam Computerized Tomography is an efficient resource for the diagnosis and location of pulp stones.
