Gemination in bilateral mandibular primary teeth is a rare anomaly. This kind of anomaly features two crowns totally or partially separated, but only one root and one root canal. At intraoral clinical examination of children we found different anatomy of mandibular primary canines with two partially separated crowns. The radiographic exams showed geminated teeth. After 3-years of follow-up, the cone beam computed tomography showed the absence of the mandibular permanent lateral incisors and the aspect of normality of the permanent canines germs. Although the gemination in primary teeth itself is considered as a harmless anomaly, its presence could indicate the occurrence of some dental anomaly in the permanent dentition. To the best of our knowledge, this is the only case of bilateral mandibular geminated deciduous teeth after 3 years of follow-up. Therefore, we highlight the importance of the early diagnosis and follow-up of this anomaly until the eruption of the permanent dentition.

La geminación dientes temporales mandibulares bilateralmente es una anomalía poco frecuente. Este tipo de anomalía presenta dos coronas total o parcialmente separadas, pero solo una raíz y un canal radicular. Al examen clínico intraoral de los niños encontramos la variación anatómica de los caninos temporales mandibulares con dos coronas parcialmente separadas. Los exámenes radiográficos mostraron los dientes geminados. Después de 3 años de seguimiento, la tomografía computarizada Cone-Beam mostró la agenesia de los incisivos laterales permanentes mandibulares y el aspecto de normalidad de los gérmenes de los caninos permanentes. Aunque la geminación en dientes primarios se considera como una anomalía no patológica, su presencia puede indicar la presencia de alguna anomalía dental en la dentición permanente. Según nuestro nuestro conocimiento, este es el único caso de dientes temporales geminados mandibulares bilateralmente tras 3 años de seguimiento. Se destaca la importancia del diagnóstico precoz y el seguimiento de esta anomalía hasta la erupción de la dentición permanente.

The rate of bariatric surgery has significantly risen in the past decade as an increasing prevalence of extreme obesity can be observed. Although bariatric surgery is an effective therapeutic modality for extreme obesity, it is associated with risk factors affecting also oral health. Based on an overview of the current literature, this paper presents a summary of dental manifestations in bariatric patients. Bariatric surgeries are associated with an increased risk for gastro-esophageal reflux which in turn might account for the higher amount of carious and erosive lesions observed in bariatric patients. As a result, also dentin hypersensitivity might be observed more frequently. The current data indicate that recommended postsurgical meal patterns and gastric reflux might increase the risk for dental lesions, particularly in the presence of other risk factors, such as consumption of sweet-tasting foods and acidic beverages. Further research is needed to evaluate the correlation of bariatric surgery and the development of dental diseases.
