Dimorfismo sexual en mandíbulas humanas revisión de la literatura sexual
(2016) Carla David; Yimaira Gamboa González; Nancy Díaz
When skeletal remains are found, there are some key elements to start a bio-anthropological study, they are: sex estimate and date of death of the remains. Simultaneously, it must take into account that populations vary according to their phylogenetic and evolutionary origins, sex, age and character of each individual. Sex in species varies according to its phylogenetic origins in size and shape, this variation is called sexual dimorphism. The precise estimation of sex, when complete skeletons are found, is based on morphological characteristics of pelvis, but this is not always present, that is why, methods based on other osseous structures are needed. Mandible is the strongest facial bone, despite of time, due to their physical characteristics, retains its morphology, showing sexual dimorphism. Therefore, the objective of this update is to describe methods of determining sexual dimorphism in skeletal remains of human mandibles. Narrating the use of multiple metric and non-metric studies to determine sex variants. Some methods have advantages and disadvantages in terms of use. Morphological method is based on morphological differences that arise genetically linked to sex and metric methods consist of the metric measurement of certain dimensions on a variety of mandibular structures designed according to sex, but that are standardized for each population. Finally, the application of these metric parameters along with morphological characteristics could be an useful tool for forensic dentistry to discriminate sex in the mandible
Reabsorción radicular interna: reporte de un caso
(2010) Yimaira Gamboa González; Morelia Hernández
The Internal Resorption is a rare pulpar pathology. It generally occurs in permanent teeth, mainly in maxillary central incisors. This illness is associated to inflammatory processes of the pulpo-dentinal complex. It may be temporary or progressive. In this report, a case of internal inflammatory resorption is presented, with root canal calcification at the middle third and apex in the upper left lateral incisor in a 52 year-old patient. During the clinical examination she had a slight and spontaneous pain, and the radiographic examination showed a large internal resorption as well as an external resorption in the upper left central incisor. It was decided to apply conventional endodontic treatment: The root canal was obturated with calcium hydroxide cement (Sealapex®) in order to seal the defect. It was restored at the coronal level. There were clinical and radiographic examinations during 18 months, where it was seen that the internal resorption process stopped.
Tratamiento de la reabsorción radicular interna: Reporte de casos clínicos.

Internal root resorption (IRR) is generally an asymptomatic pathologyassociated with traumatisms and dental pulp severe infections, in which clastic cells destroy the internal root canal dentinal walls. It is radiographically observed as a radiolucent area in the root canal. The treatment of choice can vary among endodontic therapy, surgical therapy, or even the combination of both.The endodontic therapy’s aim is to eliminate the granulation tissue and the bacteria existing in the root canal and in the defect area. Therefore, it is important to consider the physical and chemical properties of the obturation material, which has to guarantee a proper sealing and to possess antimicrobial effects.Some of the obturation materials are calcium hydroxide (Sealapex®) and MTA (Mineral Trioxide Aggregate); the choice depends on the dentist’s preference.The present paper aimed to explain the endodontic treatment of two cases of IRR, using Sealapex® as obturation material and gutta-percha (lateral compaction technique). In both cases, the clinical and radiographic follow-ups showed a successful treatment of the IRR, using this obturation material and this technique for obturating.
Tratamiento multidisciplinario de lesión endoperio. Reporte de caso clínico
(2014) Yimaira Gamboa González; V B María Moreno
Desde el punto de vista embriologico, la pulpa y el periodonto comparten el mismo origen por lo que se mantienenconexiones anatomicas y vasculares entre ambos tejidos, siendo este un factor determinante en el origen de las lesionesendoperio, tambien conocidas como lesiones combinadas. Estas lesiones tienen su origen en una anormalidad endodonticaque avanza hacia un defecto periodontal existente, lo que disminuye considerablemente el soporte del diente involucrado.Una lesion endoperio puede verse agravada por un tercer elemento como lo es el trauma oclusal, el cual intensifica el procesode destruccion de hueso alveolar. El presente articulo tiene como objetivo reportar un caso clinico de lesion combinada en unincisivo central superior derecho, con tratamiento de conducto previo y adicionalmente diente pilar de una protesis fija sujetaa contactos oclusales nocivos, el cual fue tratado de manera integrada dada la naturaleza de la lesion. Se realizo retratamientode conducto acompanado de terapia periodontal de raspados y alisados radiculares, asi como reemplazo de la protesis fijadefectuosa, tomando doble pilar para la elaboracion de la nueva restauracion fija. Se realizaron controles clinicos,radiograficos y ajustes de oclusion, tanto a la protesis provisional como a la definitiva, observando la evolucion satisfactoriadesde el punto de vista endodontico y periodontal. Se plantea continuar controles clinicos y radiograficos posteriores paraseguir la evolucion del caso. Multidisciplinary treatment of endo-perio lesion. Clinical case report Abstract From an embryological point of view, the dental pulp and the periodontium share the same origin. Therefore, those tissuesmaintain anatomic and vascular connections which are determining factors in the origin of endo-perio lesions, also known ascombined lesions. Those lesions’ origin is an endodontic abnormality that reaches the existing periodontal defect; as a result,the affected tooth’s support diminishes significantly. An Endo-perio lesion can be aggravated by a third element as theocclusal trauma, which intensifies the destruction of the alveolar bone. The present paper aimed to report a clinical case ofcombined lesion in an upper right central tooth with a previous root treatment that was also the abutment tooth of a fixedpartial denture subject to damaging occlusal contacts. Due to the nature of the lesion, it was treated in an integrated way.Endodontic retreatment was performed, as well as scaling and root planning. The fixed partial denture with defects wasreplaced by a new one with two abutments. Clinical and radiographic examinations were performed, as well as occlusionadjustments to the provisional and definitive prostheses. A satisfactory endodontic and periodontal evolution was observed.Further clinical and radiographic follow-ups will be performed in order to monitor the evolution of the case.
