We present a systematic review of the biomaterials used in the regeneration of the alveolar ridge at the loss of three-dimensional bone volume, in order to summarize the results obtained in the last fifteen years to inform the dental community effectiveness thereof. Scientific evidence indicates the effectiveness of hydroxyapatite, connective tissue, bone tissue, plasma rich in growth factors and chitosan in the regeneration of the alveolar ridge. Is demonstrated healing of soft tissue and bone regeneration progressive use of hydroxyapatite, is also highly compatible. With the use of connective tissue is recorded soft tissue augmentation in width and height, provided with a favorable color healing. Bone tissue has become the choice of filler material in reconstructive procedures maxillary alveolar atrophy to be a common component and accessible. The use of plasma rich in growth factors optimized maturation stimulates the soft tissues and bone formation, alveolar ridges equally treated with chitosan showed that it exerts an antimicrobial function, wound healing, analgesic. We recommend further research and clinical studies that demonstrate the effectiveness of chitosan in humans.

Mouth breathing is a common habit in patients of developing age, the tongue is located in a descending position, deforming the palate as it deepens. According to the literature, there are clinical and cephalometric variations in detectable mouth-breathing children, however, no studies have been found related to the description of the clinical and cephalometric characteristics of mouth-ventilators attended at the Children's Clinic of the Santa Elena Module of the Faculty of Dentistry, ULA. The objective was to determine the clinical and cephalometric characteristics obtained from the medical records of mouth-breathing patients treated at the Children's Clinic of the Santa Elena Module between 2008 and 2018.

The population was determined by the medical records of the children seen at the Children's Clinic of the Santa Elena Module diagnosed as oral respirators between 2008 and 2018. Descriptive statistics were used for the presentation of the results, and for the processing of the data by the SPSS software. . This study concluded that the mesoprosopo facial type, convex profile, as well as the deep pointed palate predominated in terms of clinical characteristics. Regarding the cephalometric characteristics, they were found in upper and lower E, ANB, SN-SGN and ENA-Me were above the norm, while the SNB angle and the interincisal angle were lower than the norm.

(2021) Sandra Parra
La presente investigación pretende exponer meridianamente el régimen jurídico fiscalizador de la tasa del Timbre Fiscal del Estado Bolivariano de Mérida, a los puros fines de describir pormenorizadamente su régimen jurídico estadal, y, de igual manera, el régimen jurídico fiscalizador del mencionado tributo por parte de la Administración Tributaria del Estado Mérida. El método empleado fue el dogmático lege ferenda. La investigación concluyó, que dicho tributo del indicado Estado Mérida como miembro de la singular federación venezolana posee un régimen jurídico sustantivo sencillo, claro y raso, aunque normativamente transparente desde el enfoque de la seguridad jurídica. No obstante, el Estado Mérida no posee su propio régimen jurídico fiscalizador, pues el Estado Mérida requiere del Código Orgánico Tributario nacional .De tal manera, que la autonomía tributaria del Estado no existe, pues la Gobernación debe acudir a la legislación nacional para cumplir con su inmanente función fiscalizadora, determinadora y recaudadora tributaria estadal.
