Objective:
To compare the immediate microleakage of carious fissures sealed with a caries infiltrant covered by a flowable composite or solely with a flowable composite.
Material and Methods:
Extracted carious molars (n=20) were selected and paired among the experimental groups according to caries progression scores. Experimental groups (n=10) wer...

... micro-CT, Kontich, Belgium), using the following parameters: ring artefact correction (5), beam hardening correction (75%) and standardized contrast limits between 0 e 0.1. After visual analysis of the whole specimen volume (DataViewer, Bruker micro-CT, Kontich, Belgium), each tooth was classified according to the caries progression scores described in Figure 1. Specimens classified as D3 were excluded from the initial sample (n=16) as conventional restorative treatment is normally indicated in these cases, rather than sealing [20]. ...

Aim: The longevity of restorative materials depends on the resistance to masticatory forces. The present study was undertaken to evaluate the
mechanical and microleakage properties of Cention-N with glass ionomer cement (GIC) and composite restorative materials.
Materials and methods: A total of 45 specimen blocks were prepared with 1...

... The success of fissure sealants and the materials used to prevent caries is measured mainly by the rate of retention [2]. A partial loss of the sealant may cause plaque accumulation and the retention of nutrients, which leads to marginal leakage and, thus, to caries developing under the sealant [10]. However, it should be noted that a sealant is rarely retained completely over the surface for a lifetime so it should be monitored closely and re-applied when necessary. ...
... "Sealing fissures" is now counted as a therapeutic procedure because not only the unconventional anatomy of fissures is protected from bacterial invasion but also it also has the ability to arrest existing caries lesion [10,16]. Additionally, many other restorative materials are used as fissure sealants, such as resin or glass ionomer-based materials. ...
... Due to caries or traumatic/malfunctional forces, failures might occur at the margins of fissure sealants. An adequate marginal adaptation of the sealant will minimize the risk of gap formation and marginal leakage, which may lead to secondary caries and eventually to pulpitis [10]. In a recent meta-analysis, the fluoride-releasing fissure sealants were reported as having survival rates of between 73.4% and 99.3% regarding retention after three years [11]. ...
Objectives:
The purpose of the present clinical evaluation was to investigate the effect of a fissure sealant and a flowable composite at fissures of permanent molars in terms of retention and caries-incidence rates over a 36-month period.
Methods:
Thirty-four patients, ages varied from 16 to 22 years, diagnosed with at least 2 non-cavitated pit-and-fissure caries in the first and second molars were involved in the study. A total of 220 sealants, were placed in 117 upper molars and 103 lower molars. Teeth were sealed with either a flowable resin composite (Tetric Evo Flow) or a sealant material (Helioseal F)(n=110). Each restoration was evaluated in terms of retention and caries incidence at 6, 12, 24 and 36 months according to their location as well. Data were analyzed using Mann-Whitney U, Friedman and 1-way ANOVA tests at p < 0.05.
Results:
Tetric Evo Flow showed total retention with 95.5%, 93.8%, 88.5% and 80.2% at 6, 12, 24 and 36-month follow-ups respectively, while Helioseal F had retention rates of 95.5%, 94.8%, 85.4% and 80.2% respectively. After 36-months, there were 6 subjects totally lost in Helioseal F group, whereas 7 of the Tetric Evo Flow sunjects were totally lost. Caries development was firstly detected at 12-month evaluation for both of the materials however, no significant differences were observed among materials in retention rates or caries incidence after 36-month follow-ups (p>0.05).
Significance:
Using the flowable composite found as effective as the fissure sealant after 36-months regarding retention and caries incidence rates.
In recent years, due to a better understanding of the caries pathology and advances in dental materials, the utilization of non-invasive and minimally invasive techniques that delay/obviate the need for traditional restorations has started gaining momentum. This literature review focuses on some of these approaches, including fluoride varnish, silver diamine fluoride, resin sealants, resin infiltration, chemomechanical caries removal and atraumatic restorative treatment, in the context of their chemistries, indications for use, clinical efficacy, factors determining efficacy and limitations. Additionally, we discuss strategies currently being explored to enhance the antimicrobial properties of these treatment modalities to expand the scope of their application.
