“…Theoretically, penetration is inversely proportional to viscosity. Thus, an unfilled resin would be penetrated more deeply into the fissure system and, therefore, perhaps be better retained according to the results of previous studies 21,34) . In this regard, the unfilled, resin-based sealant Clinpro Sealant showed the highest and the highly-filled resin-based sealant Grandio Seal showed the least penetration depth scores in non-invasive groups in this study.…”

The aim of the study was to evaluate microleakage and the penetration-depths of different fissure-sealant materials applied with/ without enameloplasty after cyclic aging. One-hundred-sixty mandibular molars were divided into non-invasive and enameloplasty preparation groups and eight material subgroups, including: flowable composites (microhyrid, nanohybrid, and nanofilled), three resin-based (unfilled, filled, and highly-filled), a giomer-based, and a glass-ionomer-based fissure sealant. Specimens were subjected to two-year cyclic chewing and brushing simulation. After 5% basic-fuchsin dye penetration, specimens were sectioned and scored under stereomicroscope. Kruskal-Wallis statistical data showed that preparation type significantly affected the penetration of all tested materials (p<0.05), but not significantly affected microleakage (p>0.05). Flowable composites showed the best and the glass-ionomer-based sealant showed the worst penetration and microleakage. Slight preparation of fissures is not important in microleakage. However, enameloplasty significantly enhanced the depth of penetration of the sealants. Flowable composites offer promising results at the fissure sealing.

“…In showed the presence of 58.8% of the study population having sealant placed in at least one of their teeth. Perceived reasons for this low utilization of sealants observed in our study maybe due to low utilization of dental services, lack of public knowledge regarding sealants and cost effectiveness [20][21][22][23][24].…”

Background: Pit and fissure sealants are one of the most effective preventive treatment for dental caries in children. Knowledge of prophylactic treatments like sealants among parents and teachers play major role in prevention of dental caries. Objectives: To assess the awareness of sealants among parents and teachers of the participating children and to assess the extent of sealant use among private dental practitioners. The study also assess the presence of sealants in the study population. Methodology: 949 school children aged 6-14 years were selected from 20 different schools. The children were selected using multistage sampling technique. Closed ended questionnaires were provided to all participant children parents. Similar questionnaires were also provided to the 274 teachers working in the selected schools. The responses from these questionnaires were used to assess the awareness and knowledge of parents and teachers regarding pit and fissure sealants. 120 private dental practitioners practicing in Kannur district were also provided with questionnaires to assess their knowledge and attitude regarding pit and fissure sealants and also to assess the extent of use of sealants in their practice. The results obtained from the survey was tabulated and statistically analyzed using chi square test. Results: The results showed that 2.85% of the examined children had pit and fissure sealants in their oral cavity. Out of the 857 parents only 8.63% of them reported prior knowledge about sealants. Among the 274 teachers surveyed 15.7% of teachers reported prior knowledge about sealants. Among the 120 private clinicians who participated almost 25% reported that they use dental sealants in their practice. Interpretation and conclusion: The present study revealed that the awareness of pit and fissure sealants among parents and teachers is low and the frequency of sealant use by private practitioners was also noted to be low.

“…In addition to the caries mechanism, the commonly assumed rationale of fissure sealant effects were integrated into the DAG, as follows: i) barrier function between acidogenic oral plaque bacteria and mineral crystals in tooth enamel (15), ii) sealing off oral plaque bacteria from carbohydrates (8), iii) exposure of mineral crystals in the tooth enamel to fluoride released from sealant materials (9).…”

“…Within the established DAG of the caries mechanism (14) and the rationale for fissure sealant effects (8,9,15), the logical framework of the proposition that sealant retention is a proxy outcome for caries prevention was investigated. For this purpose, the logical rules of Hypothetical syllogism (HS) and Reductio ad absurdum (RAA), as well as the logical Law of double negation (LDN) and the Law of contradiction (LOC) were applied.…”

The logic behind the use of fissure sealant retention as a proxy outcome measure for dental caries prevention

Fissure sealant retention is traditionally considered as a proxy measure for caries prevention. This study investigated the logic behind this proposition, and its validity. A logical framework of the proposition was established. The mechanism of caries development was transferred into a Directed acyclic graph, and this was used to investigate the logical framework. The sensitivity and specificity of full sealant retention in the prediction of dental carious lesion development and the number of false positive/false negative prediction rates were computed. The sensitivity/specificity was statistically compared to that of random values. A contradiction in the logical framework was identified. The mean sensitivity/specificity was 37.9% (SD = 27.8%) and 67.6% (SD = 28.4%), respectively. When these values were compared against random values (30.5%, SD = 25.7% and 58.7%, SD = 31.6%), a non-significant sensitivity (P = 0.06) and a borderline higher specificity (P = 0.04) were observed. The overall false prediction rate was 33.7%, with 16.9% and 16.8% false negative and false positive predictions, respectively. The sensitivity/specificity was too low and the false prediction rate was too high to consider retention a valid proxy for caries prevention. The logic behind the investigated proposition is flawed, contradicted by the current empirical evidence, and thus invalid.
