Elaboração de um Jogo Digital Educacional sobre Saúde Bucal Direcionado para a População Infantil

Objective: The aim of this study was to develop an educational oral health digital game for 5-to-7-year-old children. Method: The game, called “Dr. Trata Dente”, was based on the approach to three different oral health-related topics: a) bacterial plaque and the main diseases caused by it; b) oral hygiene methods for bacterial plaque control; c) dental caries and preventive measures for this disease. These topics were discussed in sequential order in three different stages of the game. Dr. Trata Dente is represented by the figure of a little super-hero dentist, who talks to the children about oral health during the game. The game is sub-divided according to its propositions to the children, into an association game, a memory game and a coloring game. After its development, the game was evaluated by three professionals of each of the following areas: Dentistry, Pedagogy and Psychology (n=9), who verified the suitability of the concepts presented in the game as regards oral health, linguistic abilities worked with the children, fulfillment of the intended didactic criteria, and the playful aspect of the game. Results: According to the dentists, the dental concepts presented in the game are adequate. According to the pedagogues, the choice of a super-hero was correct and the given explanations are well elaborated, organized and have accessible language, although long. For the psychologists, the game has a potential positive effect on the children’s learning, but there should be more interaction of the character with the children. After this evaluation, changes were made in the game according to the professionals’ suggestions. Conclusion: It was concluded that in spite of the suggested alterations, the game is suitable for teaching oral health by means of children’s play.

Importância da correta confecção do prontuário odontológico para identificação humana: relato de caso

The clinical records correspond to a set of documents where all information of the patient is stored. When properly confectioned and filed by the dentist, it may serve as a tool for success in dental expertise. The aim of this paper is to present the importance of proper confection of dental records in human identification by means the presentation of a case of identification, occurred in a São Paulo state city. The notes present in the dental records of the alleged victim were very poor, even with a contradiction. However, having endodontic treatment been performed, the comparative analysis between the radiographs of the skull of the victim (postmortem) and the endodontic treatment of tooth 22 (antemortem) permitted to observe total coincidence between the details of such treatment, and anatomical features present in other dental elements. These important parameters of comparison indicated that the body was of the suspect and, due to the number of coincidences, it could not belong to another individual. Nevertheless, the clinical documentation provided was deficient, and presented contradictory data. Because of its fundamental importance for human identification, it is essential that dental professionals take the necessary care to ensure its proper confection and custody, seeking to make the clinical records also an efficient instrument of consultation in identification cases.

Conhecimento de mães sobre os procedimentos de emergência nos casos de avulsão dentária

Introduction: Despite tooth avulsion following trauma being relatively common in children, the available studies show that adults have limited knowledge about it. Aim: The purpose of this study was to assess, by a questionnaire, the mothers’ general knowledge about the immediate management of tooth avulsion. Material and method: This descriptive study was carried out on a convenient sample of mothers (n= 65) who participated of the “Pastoral da Criança”, from Araraquara, SP, Brazil. The questionnaire comprised 15 questions about personal data and knowledge on tooth avulsion management. Results: Participants were, on average, 35 years old. A total of 30.8% of the mothers reported that their children suffered dental trauma. The majority had never received advice on this subject (76.9%); and did not know how teeth are kept in the dental arch (69.2%). Almost a half of the sample believed that an avulsed tooth can be replanted (49.2%). In relation to the management of tooth avulsion, 40% of them would clean the avulsed tooth with water, even if it was not dirty (38.5%). Most of them (69.2%) would take the tooth by hand for cleaning purposes, regardless the tooth region; and believed that brushing the tooth was important to take the dirty out (67.7%). Conclusion: The general knowledge of mothers about the immediate management of tooth avulsion was considered inadequate endangering the successful treatment of tooth avulsion.

Conhecimento de mães sobre promoção de saúde bucal em bebês

The aim of this study was to assess the knowledge level on oral health promotion for babies of all mothers (n=60), aged 18-42 years, assisted in the Preventive Dentistry Clinic of the Faculty of Araraquara, at Universidade Estadual Paulista (UNESP), during the period 2005-2008. Methods - An interview was performed using a questionnaire with 18 open and five closed questions about knowledge and practices related to caries prevention as well as demographic information. Methods - The majority believed that breast milk does not cause caries (73,3%), that caries is not a transmissible disease (51,6%) and that anatibiotics cause caries (63,3%). Almost all mothers (93,3%) responded that brushing teeth could prevent the disease, action that should be initiated since first tooth erupts (75%). For 73,3% of the respondents, the use of dental floss should be initiated onle after all deciduous teeth erupt. Results - The majority (83,3%) knew what was fluoride, but a third of them (33,3%) did not know the best time to start using it. The dentist counseling related to oral health of babies was considered imoprtant by 96,7% of mothers. Conslusion - The mothers presented good knowledge about baby's oral hygiene, however, they did not know about other important variables for oral health promotin of babies.

Replantation as treatment for extrusive luxation

In the treatment of extrusive luxation cases, it is important that the repositioning of extruded tooth in the socket is done as soon as possible. If this does not occur, periapical clot becomes organized and makes replantation difficult reposition. In this article the patient referred to the Clinics for dental trauma sustaining extrusive luxation of the maxillary right central incisor. The patient reported having suffered a bicycle accident 12 days before, which caused traumatic tooth injuries. The repositioning was attempted without success and an alternative form of treatment was necessary to solve the case. Intentional tooth replantation, which is the deliberate extraction of the tooth and its replantation, was indicated. This technique allows clot removal and correct repositioning of the extruded tooth. Care should be taken as endodontic treatment is required for the prevention of subsequent infection-related resorption. Intracanal dressing with calcium hydroxide was used for 30 days before final root filling. Splint, systemic antibiotics and avoidance of further damage to the root surface is also important. After 49 months, showed clinical and radiographic characteristics of normality and demonstrates the availability of this technique to adversity in trauma.

Fracture resistance of simulated immature teeth after different intra-radicular treatments

The aim of this study was to evaluate the fracture resistance of simulated immature teeth after different intra-radicular treatments. Crowns and roots of bovine incisors were cut transversally and removed to simulate immature teeth. Root canal preparation and flaring were performed using a bur in crown-apex and apex-crown direction. The samples were distributed into 5 groups (n=10): Positive control (PoC) - no root canal flaring or filling; Negative control (NeC) - teeth were sectioned and their root canals were flared; Direct anatomical glass fiber post (RaP) - #2 Reforpost main glass fiber post relined with composite resin; Double tapered conical glass fiber posts (ExP) - #3 Exacto glass fiber post; and #2 Reforpost main glass fiber + Reforpin accessory glass fiber posts (RrP). In RaP, ExP and RrP, 4.0-mm apical plugs were done with MTA Angelus. The specimens were embedded in polystyrene resin inside cylinders and the periodontal ligament was simulated with a polyether-based impression material. The specimens were submitted to compressive fracture strength test (0.5 mm/min at 135° relative to the long axis of the tooth) in a servo-hydraulic mechanical testing machine MTS 810. Data were subjected to one-way ANOVA and Dunnett's C or Tukey's tests (α=0.05). The control groups (PoC and NeC) showed lower fracture strength than the experimental groups. NeC presented the lowest resistance and ExP presented the highest resistance among the experimental groups. The flaring procedures produced a detrimental effect on the fracture resistance of the bovine teeth. Glass fiber intra-radicular posts increased significantly the fracture resistance of simulated immature teeth.
