Electromyographic Study of the Masseter Muscle after Lower Third Molar Surgery International Journal of Morphology
Barros,Tarley Eloy Pessoa de; Campolongo,Gabriel Denser; Oliveira,Reginaldo Perilo de; Alves,Nilton; Oliveira,Reinaldo José de.
Third molar extraction surgery is one of the most frequently performed procedures in the areas of buccal-maxillofacial traumatology and surgery. The post-surgery evolution was evaluated based on the clinical evidence obtained so far. The objective of this study was to analyze the post-surgery clinical evolution of the masseter muscle by means of surface electromyography, to evaluate muscle activity. Four analyses were performed: one pre-surgery, to register the normal activity, and three in post-surgery: on the 7th, 14th and 21st postoperative days, in a sample of 30 patients. On the 21st day, there was near normal recovery of the electrical signal of the masseter in women, but in men this activity did not reach normal levels. Surface electromyography is a...

Evaluation of Dental Eruption of Third Molars in the Length of Mandible International Journal of Morphology
Sousa Filho,Gilberto de; Amorim Júnior,Adelmar Afonso de; Lins,Carla Cabral dos Santos Accioly; Silva Neto,Joaquim Celestino da.
The aim of this work was to evaluate the eruption of the third molar teeth in the length of the mandible using the orthodontic documentation obtained between 2005 and 2006 as sampling method, a total of 193 cases of both sexes. The cephalometric analysis and panoramic radiographic studies were chosen from two clinics randomly selected in the city of Recife ­ Pernambuco - Brazil. It was analyzed the linear size of mandibular bone by the use of McNamara's Cephalometric Analysis, and also the presence or not of dental retention of inferior third molar teeth with the help of panoramic radiographic study, evaluating the commitment of these retentions with the effective length of mandible. The work concluded that when the effective mandibular length is small...

Lower Third Molar Region International Journal of Morphology
Suazo Galdames,Iván.
The lower third molar region is an important region for the odontostomatological practice, since it presents a great amount of pathological processes related to the development and eruption of the third molar; thus having a considerable number of surgical interventions. Despite its importance, this region is not accounted for in anatomical terminology nor is it described in topographic anatomy; and in spite of the great number of studies that analyze the surgical anatomy of the region, it is necessary to systematize the description of its boundaries, planes, content, risk elements, anatomical repairs, etc.; therefore, the purpose of the present article is to review the modern concepts related to the surgical anatomy of the lower third molar region and to...

Molar polymorphism and variation in tooth number in a semi-aquatic rodent, Neusticomys oyapocki (Sigmodontinae, Ichthyomyini). Mastozool. neotrop.
Catzeflis,François; de Thoisy,Benoit; Ferreira da Silva,Maria Nazareth; da Silva,Claudia Regina.
Newly collected specimens of the rare semi-aquatic mouse Neusticomys oyapocki (Rodentia: Sig­modontinae: Ichthyomyini) exhibit individual variation in tooth number. Whereas this Guianan ichthyomyine had previously been described as having only two molars per jaw quadrant, our study examines 31 specimens, of which 12 exhibit from one to four additional third molars. Specimens with at least one third molar come from 6 localities spanning Suriname, French Guiana, and the Brazilian states of Amapa and Para. Third molars reported in this species are tiny (on average 0.55 mm crown length), about half the size of second molars. We show that N. oyapocki has between 8 and 12 molars, which represents extensive variation in the number of teeth. This kind of dental...

Morphometric Relationships between the Mandibular Canal and the Molar Teeth: A Tomographic Analysis Report International Journal of Morphology
Sánchez Trocino,Benjamín; Díaz Acevedo,Jacinto Armando; Villanueva-Vilchis,Maria del Carmen; De la Fuente- Hernández,Javier; Sarmiento Rebolledo,Leonardo Daniel; Sánchez Amador,Alejandro Ricardo; López Tirado,Diego Iván.
Some dental treatments that are performed in the mandibular teeth involve manipulation of anatomical structures near the dental periapex, so it is likely to cause nerve damage due to the proximity of the inferior alveolar nerve with the apices of the mandibular teeth, mainly in the molar area. The aim of this study was to determine through Computed Tomography (CT) scan the existing distance between the mandibular canal and the anatomical structures adjacent to its path which will help to reduce the risk of injury to the inferior alveolar nerve during the different dental treatments developed in this zone. A cross-sectional study was performed where the study population consisted of 50 patients of both sexes, between 20 and 30 years with a full dentition...
