“…Este fato pode ser indício de que a técnica de aplicação não está sendo adequada, podendo haver, por exemplo, negligência quanto ao isolamento do campo operatório. Note-se que este fator é mencionado por diversos estudos como sendo fundamental para a retenção dos selantes de fossas e fissuras 4,[11][12][13][14][15][16]21 . Azarpazhooh, Main 4 (2008) recomendaram que todos os molares permanentes fossem selados, enquanto Beauchamp et al 5 (2008) preconizaram que os molares permanentes fossem selados após avaliação de risco de cárie do paciente.…”

“…Alguns fatores são fundamentais para assegurar a retenção deste material na superfície dentária: morfologia das fossas e fissuras, propriedades físico-químicas do esmalte dentário, grau de limpeza da superfície dentária, viscosidade do material usado como selante e qualidade na técnica de aplicação [11][12][13][14][15][16] . O cuidado com a técnica merece destaque, na medida em que cada etapa do protocolo deve ser rigorosamente executada.…”

ResumoIntrodução: Selantes de fossas e fissuras são indicados para prevenir lesão de cárie em superfícies oclusais. Objetivo: O objetivo deste estudo foi avaliar os selantes de fossas e fissuras aplicados por estudantes do Curso de Graduação em Odontologia da Universidade Regional de Blumenau (FURB), Santa Catarina. Material e método: O estudo descritivo retrospectivo desenvolveu-se em três etapas: na primeira, procedeu-se à análise dos prontuários do Setor de Triagem, tendo como critério de inclusão a existência de radiografias dos dentes selados. Na segunda etapa, analisaram-se as radiografias dos prontuários selecionados e a história clínica da criança. A terceira etapa foi realizada por meio de exames clínicos e radiográficos, pelos quais eram verificadas as condições dos selantes de fossas e fissuras. Resultado: Foram analisados 800 prontuários, sendo selecionados 131 (16,37%) para a segunda etapa, quando se observou que 321 selantes de fossas e fissuras foram aplicados. Compareceram à consulta de controle 119 (90,84%) crianças, ocasião em que se confirmou a aplicação de 160 (49,85%) selantes resinosos, 126 (39,25%) com cimento de ionômero de vidro e 35 (10,90%) com resina flow. Foram observados 296 (92,21%) selantes em dentes permanentes. Ao exame clínico, verificou-se que 114 (35,51%) selantes haviam sido perdidos totalmente em diferentes períodos de tempo. Nenhuma lesão de cárie foi observada em 294 (91,59%) dentes selados. Conclusão: Verificou-se que os selantes de fossas e fissuras, aplicados por estudantes do Curso de Odontologia da FURB, foram eficazes na manutenção da maioria das superfícies dentárias livres de lesão de cárie, mesmo quando foram perdidos parcial ou totalmente.Descritores: Selantes de fossas e fissuras; cimentos de ionômero de vidro; estudantes de Odontologia. AbstractIntroduction: Pit and fissure sealants are indicated to prevent caries in occlusal surfaces. Objective: The aim of this study was to evaluate pit and fissure sealants applied by Dentistry undergraduate students of the Regional University of Blumenau (FURB), Santa Catarina. Material and method: The retrospective descriptive study was developed in three stages: the analysis of the records of the Department of Screening, being used as an inclusion criterion the existence of X-rays of the sealed teeth. In the second step we analyzed the radiographs of selected records and medical history of the child. The third step was performed by clinical and radiographic examinations, when conditions of pit and fissure sealants were verified. Result: We analyzed 800 medical records, and selected 131 (16.37%) for the second step, where it was observed that 321 pit and fissure sealants were applied. 119 (90.84%) children attended the control dental appointment, when confirmed the application of 160 (49.85%) resin, 126 (39.25%) glass ionomer cement and 35 (10.90%) flowable composite. We observed 296 (92.21%) sealants in permanent teeth. The clinical examination revealed that 114 (35.51%) of the sealants were completely lost at different pe...

“…This in vitro study also proves that occlusal morphology is a limiting factor for penetration of fissure sealants. Maximum depth of penetration, good adaptation and limited marginal microleakage are more important than the complete penetration of the sealant to the base of the fissure [15,16].…”

Background and aims. Pit and fissure sealant placement corresponds to an effective approach of the prevention of caries on occlusal surfaces. Fissure morphology and dental material characteristics are the key factors for sealant effectiveness. The aim of this in vitro study was to compare the penetration ability of two commercially available pit and fissure sealants. Methods. Twenty sound human premolars extracted for orthodontic purpose have been sealed according to manufacturer's instructions as follows: Group I (n=10), lightcured unfilled resin-based sealant, Admira Seal® (Voco GmbH); Group II (n=10), resin modified glass ionomer sealant without varnish, GC Fuji Triage® (GC Corporation). The teeth have been sectioned buccal-lingually in the middle of the occlusal surface, and the sections were examined at 40x with an inverted microscope. Results. Penetration of the sealants was found to be greater in U-type fissure pattern (91.69%) followed by V-type (75.42%), IK-type (71.24%) and then in I-type (63.98%). The depth of penetration of GC Fuji Triage® (82.85%) demonstrated to be superior to Admira Seal® (76.28%). Conclusion. U fissure design was more common than other fissure patterns and showed significantly higher penetration for the two type of sealants evaluated. Resin modified glass ionomer sealant used in the present study perform comparably with the filled resin sealant.

“…55 Shallow fissures may be more likely to be thoroughly cleaned and etched than deep fissures. 56 To overcome the problems of deep constricted fissures, a mini-invasive technique for the placement of sealants has been employed. 57 However, in the context of contemporary knowledge, the rationale for the mini-invasive technique needs to be reevaluated for the following reasons.…”

Community service-learning (CSL) in predoctoral dental education might be an effective tool for increasing sealant use by dentists-thus benefitting underserved children while facilitating students' learning of a clinical procedure in a real-life setting. This study reviewed the scientific literature on this topic in order to 1) evaluate the reasons for low sealant use among dentists, 2) consider important aspects of sealant use in community settings, and 3) identify best practices to use as guidelines for CSL regarding sealant use. As background, the MEDLINE database was searched with the key words "dental sealants" for human and laboratory studies in the English language. A total of 205 relevant articles were identified and overviewed. We found that the low use of sealants relate to dentists' orientation toward restorations rather than prevention, distrust in sealant treatment, lack of confidence in caries risk assessment, and concern about sealing over caries. The aspects to consider in the CSL projects are acquisition of knowledge and necessary skills of operators, cost-benefit approach to sealant placement, and meticulous sealant placement procedures, including the necessity for a short-term recall.

The effect of fissure morphology and eruption time on penetration and adaptation of pit and fissure sealants: An SEM study

Abstract: Even the well-applied sealant does not necessarily provide complete obturation of pits and fissures, thus necessitating periodical clinical observation to determine the success or potential failure of the sealant treatment.
