Kissing molars (KM) or rosette formation is a term that is used to describe impacted teeth contacting occlusal surfaces in a single follicular space and their roots pointing in opposite directions. In some cases kissing molars can be seen but occurrence of bilateral kissing molars is extremely rare phenomenon in the dental literature and the aetiology of this phenomenon is still unknown. In this paper we describe a case and review of the literature and discuss the management of this pathology. In our case, extremely rare form of impacted bilateral kissing molars was extracted surgically. The decision of extraction of asymptomatic kissing molars represents surgical dilemma. There may be many surgical complications; on the other hand in some cases surgical intervention is unavoidable. Few treatment options were described in the literature. This phenomenon can be sign of various medical conditions that may require further investigation. In this paper, our treatment option is in agreement with the literature suggesting the surgical removal of both teeth at either side of the mandible.

Articular eminence morphology and inclination are reported to be two predisposing factors for the internal derangement (ID). The purpose of this study is to investigate the relationship between the inclination and morphology of the articular eminence and ID. The study included 70 temporomandibular joints with ID in 35 patients: 51 joints had disc displacements with reduction (DDWR) and 19 joints had disc displacements without reduction (DDWOR). All subjects underwent bilateral high resolution magnetic resonance imaging scans which were performed in the sagittal and coronal planes with mouths closed and opened. Articular eminence morphology was characterized as box, sigmoid, flattened, or deformed. Articular eminence inclination was measured at three positions: steep (from 60° to 90°), moderate (from 30° to 60°) and shallow (from 15° to 30°). The images were divided into two; DDWR and DDWOR, and these two criteria were compared. The images of the two groups were compared; while flattened form was occurred with the highest incidence in the DDWOR group, sigmoid form was the most frequent in the DDWR group and articular eminence inclination was found steeper than it was for the DDWOR group. The steepness of the articular eminence may not have a predisposing effect on the development of disc displacements. La morfología e inclinación de la eminencia articular son reportados como dos factores predisponentes para el trastorno interno (TI). El propósito de este estudio fue investigar la relación entre la inclinación y la morfología de la eminencia articular y el TI. El estudio incluyó a 70 articulaciones temporomandibulares, con TI en 35 pacientes: 51 articulaciones con desplazamiento discal con reducción (DDCR) y 19 de las articulaciones tuvieron desplazamiento discal sin reducción (DDSR). Todos los sujetos fueron sometidos a imágenes de resonancia magnética bilaterales de alta resolución que se realizaron en los planos sagital y coronal con la boca cerrada y abierta. La morfología articular la eminencia se caracterizó como una caja, sigmoide, aplanada, o deforme. La inclinación de la eminencia articular se midió en tres posiciones: empinada (de 60 ° a 90 °), moderada (entre 30 ° a 60 °) y poco profunda (entre 15 ° y 30 °). Las imágenes fueron divididos en dos; DDCR y DDSOR, y estos criterios fueron comparados. Al comparar las imágenes de ambos grupos, la forma aplanada se observó con mayor incidencia en el grupo de DDSR, la forma sigmoide fue la más frecuente en el grupo de DDCR y la inclinación de la eminencia articular se encontró más pronunciada que en el grupo DDSR. La inclinación de la eminencia articular puede no tener un efecto predisponente en el desarrollo de los desplazamientos de disco.
