Incidence of retromolar foramen in human mandibles: ethnic and clinical aspects

The retromolar foramen allows the passage of the neurovascular bundles that contribute to nutrition and innervation of the pulp and periodontium of the lower teeth. Knowledge of this anatomical variation may prevent complications in the anesthesia and surgical procedures in this area and serve as an anatomical landmark for ethnic identification. The aim of this study was to evaluate the impact of the retromolar foramen in human mandibles of adult Brazilians and discuss the clinical and ethnic related to the presence of this foramen. Were evaluated 222 human mandibles, dry, adults, Brazilians, independent of gender. The evaluation was performed by two examiners who standardized search from a previous anatomical study. The mandibles were analyzed: the presence of the retromolar foramen (bilateral or unilateral), the presence of the foramen on right and left sides, and the number of foramens present on each side. It was found that 59 had at least one mandible retromolar foramens resulting in an incidence of 26.58%. The retromolar foramen was present unilaterally in 41 mandibles and 18 bilaterally, with incidences of 18.47% and 12.16% respectively. on the right side, the retromolar foramen was present in incidences of 16.22% and 18.92% respectively The analysis of the right side of the mandibles revealed that 47.46%, 21.21% and 3.03% had one, two and three foramens, respectively The left side showed 55.93%, 16.22% and 8.11% of the 222 mandibles with one, two and three retromolar foramens, respectively The incidence of retromolar foramen in the Brazilian population is significant and should be considered in the planning and execution of procedures in several areas of clinical practice dentistry in order to avoid complications. Moreover, it was found that the incidence of retromolar foramen contributes to differentiation of ethnic groups in the area of forensic anthropology.

Perfil de cuidadores de idosos e percepção sobre saúde bucal

O objetivo deste estudo foi avaliar o perfil e conhecimento sobre saúde bucal de profissionais cuidadores de idosos, que atuam em três asilos da cidade de Araçatuba. Foram entrevistados 18 cuidadores de três instituições, com o auxílio de um formulário, visando avaliar o grau de conhecimento destes quanto aos aspectos de saúde bucal. em relação à formação escolar, 83,3% desses profissionais possuem curso técnico de auxiliar de enfermagem e 16,7% não apresentam qualquer tipo de formação técnica. Mais da metade dos entrevistados (61,11%) relatou ter iniciado o trabalho por necessidade, não por afinidade. Quanto ao conhecimento em saúde bucal, detectou-se carência de informações, sendo que a maior parte necessita de esclarecimento quanto aos problemas mais prevalentes que ocorrem na boca e muitos deles (55,56%) acreditam que a perda dos dentes faz parte do envelhecimento. Constatou-se que os cuidadores precisam ser informados sobre aspectos de saúde bucal voltados para idosos.

La salud bucal en la percepción del adolescente

Objective An individual does not always experience the best health and vitality indexes during her/his adolescence. This study evaluated young people's awareness of their oral health and the factors involved in dental maintenance and promotion Material and Method Adolescents (n=493) from the Mirim Foundation in the town of Araçatuba in the state of São Paulo, Brazil, were asked to fill in a semi-structured questionnaire. Results 68.4 % of the youngsters interviewed regarded oral health as referring to hygiene and 16.2 % to physical appearance; 53.6 % of the group perceived their oral health to be good and 24 % optimum. 90.1 % indicated oral hygiene when asked how oral health could be ensured; however, only 4.8 % mentioned brushing their tongues. Physical appearance (62.9 %) was one of the main reasons stated as being important for teeth. A statistically significant relationship was observed between perception of regular dental and mouth health and having visited the dentist at least six months beforehand (x2=30.75; p<0.05). Conclusion Even though the youngsters had a general idea regarding their oral health, its maintenance and promotion, better information should be made available regarding such topics and be approached through health education so that these adolescents can have good oral health for the rest of their lives, as well as becoming knowledge multiplying agents for those who do not have access to the same information.

Abordaje conservador y mínimamente invasivo de la hipomineralización molar-incisivo (HMI) - Relato de casos clínicos

Molar-Incisor Hypomineralization (MIH) is a qualitative developmental enamel defect that affects one to four permanent first molars, with or without involvement of permanent incisors. Enamel defects may produce many symptoms that have physical, social and psychological effects and influence day-to-day living or quality of life. The available treatment modalities for teeth with MIH are extensive, ranging from prevention, restoration, to extraction. Factors such as age, patient expectations, severity of the lesion and materials should be considered in the treatment of the patient with MIH. Restoration with composite resin is an alternative choice for posterior and anterior MIH defective teeth and its use has been show acceptable results. This article describes two clinical cases involving pediatric patients with MIH whose procedure of cavity preparation was based on the use of CVD ultrasound diamond tips and restored using composite resin obtaining favorable esthetics results after a 1 year follow-up.

Tratamiento Quirúrgico de Mesiodens en Odontopediatría

Supernumerary teeth are a relatively frequent disorder of odontogenesis that can interfere with the development of the germs teeth. This pathology is most common in the maxillary anterior area, called mesiodens, and their prevalence is generally reported to occur more frequently in male than female, in a ratio of 2:1. The aim of this article was to report the clinical procedures performed in the Clinic of Pediatric Dentistry at the Araraquara School of Dentistry when the presence of two mesiodens, radiographically shown, caused retention of permanent anterior teeth, resulting in esthetic and funcional disturb. All the surgical procedures, etiology and the importancy of the early diagnostic for the appropriate treatment was detailed described.

Hipomineralización incisivo Y molar: diagnóstico diferencial

Hypomineralized first molar often in combination with hypomineralized incisors (MIH - molar incisor hypomineralization) is a common finding in everyday practice. In this condition, hypomineralized dental enamel is fragile and soft, and it can break easily leading to an exposed dentin, and causing dental sensitivity and progression of caries lesions. The prevalence of MIH range from 3.6 to 25% in North of Europe that consider this condition a public health problem. No conclusive information was reported about the etiologic factors of MIH, however, systemic causes seem to be of importance. Several aetiological factors are mentioned as the cause of this condition and they are frequently associated with complications during pregnancy and childhood diseases during the first three years of life. MIH is frequently misinterpreted as fluorosis, hypoplasia or amelogénesis imperfect, however, this condition presents defined clinical aspects that can distinct it from the other defects.

Restauración onlay usando técnica semi-directa con resina compuesta: reporte de un caso

Posterior teeth restorations have changed the contemporary treatment philosophy influenced by the aesthetic demand of patients, progress of adhesive material science and techniques for preservation and rehabilitation of affected teeth by dental caries and trauma. The development of Onlay restorations with semi-direct technique in endodontically teeth treated aims to preserve the remaining surfaces, to reduce the possibility of fracture and polymerization shrinkage. In addition, better restoration adaptation and marginal seal, resistance to wear and dimensional stability are achieved. This case reports the rehabilitation of an endodontically treated permanent maxillary first molar in a 13 years old- patient who attended the Araraquara School of Dentistry, Brazil, using Miris 2 Composite resin with semi-direct technique and obtaining an aesthetic and functional restoration in a single appointment. The fundaments and clinical guidelines of the procedure are detailed, based on the review of the literature that supports this conservative treatment.

Influencia de diferentes intensidades de luz en la resistencia de unión de un sistema adhesivo utilizando un colorante fluorescente para su observación

The purpose of this study was to use a fluorescent dye and CLSM microscope to observe the effect of different light intensities on dentin tensile bond strength. Flat dentin surfaces were created on 16 intact human third molars and divided in 4 groups: Group G1 - halogen - KM -200R®; Group G2 - LED - Ultraled®; Group G3 - LED - UltraLume LED5® and Group G4 - LED - Biolux Single V®. For all the groups, the restoration procedure used Single Bond® adhesive, mixed with rodamin B and InTen-S® composite resin. Then, they were cut on serial sections to obtain 1 mm2 area and submitted to micro tensile test and after words, the fractures were analyzed with a digital microscope and CLSM. The statistical analysis showed that all in all groups, except Group G2, which had a significant smaller tensile bond strength ratio. The fracture mode analysis showed that there were significant differences when comparing groups G1 / G2, and G2 / G4. There is no evidence of relevant differences among the other groups. With these results, we conclude that the use of fluorescent dye and CLSM demonstrated to be a simple and nondestructive technique, and that there are evidences that light intensities influenced the dentine tensile.

The Thermafil technique showed better results in terms of sealing capacity, failures and homogeneity followed by modified Hybrid Tagger, the System B and cold lateral compaction. Conclusions. Thermafil was the technique that shown to be macroscopic, radiographic and homogeneously best over the other techniques evaluated in regard to the filling of the depressions made (AU)

Instrumentación para el registro del color en odontología

Color is an important variable in cosmetic dentistry, and it has traditionally been measured by a visual method, comparing teeth with standard color guides. In recent decades, electronic instruments have been developed to eliminate the subjective factor of visual measurement. This objective method has mainly been performed with colorimeters, spectrophotometers and the analysis of images obtained with digital cameras. These instruments have proven to be reliable with a high degree of precision and accuracy. Its use is recommended as an adjunctive tool to assess color in direct and indirect restorations, in aesthetic treatments like bleaching, and to facilitate communication with the dental laboratory. The spectrophotometer is the device that has reported better “in- vitro “ and “in -vivo” performance, being the “Vita Easyshade “ the one with more reliable results.
