Clinical Effectiveness of Air Abrasion When Compared to Conventional Acid-etching Technique in Enhancing the Retention of Pit and Fissure Sealants: A Systematic Review.

The purpose of our study was to perform a systematic review to assess and compare the effectiveness of the air abrasion technique with that of the conventional acid-etching technique performed before the placement of pit and fissure sealants. A search of studies was conducted in May 2021 using PubMed, Cochrane Library, and Google Scholar databases. Clinical trials in the English language between 1997 and 2019 were included. The quality of the studies was analyzed using the Cochrane Collaboration tool. The search retrieved 276 references, out of which seven studies were included for a qualitative analysis. In these seven studies, the risk of bias across the Cochrane tool's domains varied from low to high. All the included studies considered acid-etching as a comparator to air abrasion technique either used alone or as an adjunct to acid-etching technique. When coverage of sealants or their retentivity was compared at different time intervals, it was more in the acid-etching group than in the air abrasion group. Similarly, carious lesions were seen more in the air abrasion group than in the acid-etching group. The air abrasion technique followed by acid-etching brought superior retention properties of sealants than the acid-etching technique alone. Bhadule SN, Kalaskar R, Kalaskar A, et al.

Retention in fissure resin-based sealants in schoolchildren: the etching step importance.

Randomized controlled trial. Forty-seven schoolchildren aged 9-10 years with fully sound/noncavitated erupted first permanent molars were included and randomly allocated in control and experimental groups in a split-mouth design. 47 schoolchildren (94 molars) fissure sealants applied using self-etch universal adhesive system. 47 schoolchildren (94 molars) fissure sealants applied using conventional acid-etching technique. Retention of sealants and secondary caries incidence (ICDAS). Chi-square test. Conventional acid-etch sealants retention was superior to self-etch after 6 and 24 months (p < 0.001), but no differences were found in caries incidence after 6 and 24 months (p > 0.05). Clinical retention of fissure sealants using conventional acid-etch technique is greater than self-etch.

Clinical Evaluation of Retention of Hydrophilic and Hydrophobic Pit and Fissure Sealants in Permanent First Molars: An 18 Months Follow-up: Randomized Controlled Trial.

Deep pits and fissures are more prone to caries development due to their complex morphological anatomy. Preventive measures, such as pit and fissure sealants, can help in the reduction of dental caries. Conventional sealants being hydrophobic in nature, require isolation. Sealants which are hydrophilic have been introduced as an alternative where isolation is difficult to achieve. To compare and evaluate the retention and marginal integrity of hydrophilic pit and fissure sealant (Embrace WetBond) with hydrophobic pit and fissure sealant (Clinpro) in permanent first molars. Sealants were applied randomly using the split-mouth design technique on 80 permanent first molars in children aged between 6 and 9 years and evaluation was done at 3, 6, 9, and 18 months. The difference in retention rates between the groups was not significant using the Chi-squared test, though the WetBond group exhibited better results with 40% complete retention at the end of 18 months while in the Clinpro group, it was 37.50%. The marginal integrity in both the sealant groups was also found to be statistically insignificant. Caries incidence was found to be slightly higher in the Clinpro group. The clinical performance of Embrace WetBond was better when compared to Clinpro because of its moisture-tolerance capacity. Embrace Wetbond pit and fissure sealant can be the choice of material in cases where moisture control is a challenging issue. Gyati O, Jain M, Sogi S, et al.

Effectiveness of Fissure Sealant in Preventing Caries in Children

The main aim of this study was to evaluate the retention and effectiveness of fissure sealant&#x0D; Fisseal Extra (ProMedica, Germany) in prevention of caries in school children in&#x0D; Thamar, Yemen. Eighty five children aged 5- 12 years were selected randomly from different schools of Thamar and examined. Using a splitmouth design, the experimental teeth (maxillary and mandibular premolar and molar) were sealed with fissure sealant; while, teeth of another side of mouth acted as control group. The retention and effectiveness of sealant were carefully inspected after 1, 3, 6 and 9 months.&#x0D; The results revealed that, after 9 month, the retention and effectiveness rate was 98.3 and&#x0D; 96.9 percent respectively. Statistically, there was no significant difference between the different groups (P&lt; 0.05). The fissure sealant showed high rate of retention and effectiveness and this could be useful in control and prevention of caries in school children.

Retrospective evaluation of fissure sealants applied by dentistry students

Aim: The purpose of this study was to assess the adequacy and success in meeting protective expectations over time of resin-containing fissure sealants applied by dentistry students in our clinic. Methodology: Six-month controls were performed on 516 teeth of 85 patients aged 9–15 years. The 6-month controls of the resin-based pit and fissure sealants applied by 5th-grade dentistry students to patients presenting to the Necmettin Erbakan University Faculty of Dentistry Pedodontics Clinic between January 2022 and February 2022 were checked, and their survival was checked. The SPSS 26 statistical program was used in the analysis of the data. The statistical significance level in the study was determined as p &lt; 0.05. A total of 85 patients and a total of 516 teeth, including premolars and molars, were included in the study. Results: A total of 128 teeth were processed in the right maxilla, and total retention was observed in 102 teeth. Right maxilla; When the left maxilla (p = 0.001), left mandible (p = 0.011), and right mandible (p = 0.001) were compared in terms of total retention, a statistically significant difference was found. When the teeth were compared among themselves, the highest rate of loss, a total loss of 50%, was found in teeth 26 and 47. When the teeth were evaluated according to age, teeth numbered 14 (p = 0.001) and 24 (p = 0.001) were 9 years old, teeth 35 (p = 0.001) and 45 (p = 0.001) were 9–10 years old, and tooth number 44 (0.012). At the age of 10, the percentage of total loss was higher than in the other age groups, and a statistically significant difference was found. This suggests that the ideal isolation of the permanent premolars may not have been achieved because they do not fully erupt at the age of 9–10. Conclusion: When all the results were evaluated, it was seen that the retention of fissure sealants depended on multiple factors, and their indications should be carefully examined.

PIT AND FISSURE SEALANT APPLICATIONUSING SELF- ETCH BONDING AGENT; A LITERATURE REVIEW

Self-etch adhesive systems may be an alternative for occlusal sealant especially in young children,where simplifications in the clinical procedures are warranted.This paper describes self- etch adhesive systems and their role in the retention of pit and fissure sealant.

Retention Ability of a Glass Carbomer Pit and Fissure Sealant.

Dental sealants are an excellent means to prevent pits and fissure decay. Currently, there are multiple commercially available sealant materials. The purpose of this study was to assess the retention of glass carbomer fissure sealant and the incidence of secondary caries over a period of 24 months in comparison with a resin-based sealant. Materials and Methods: We included 32 children in the study, with ages between six and eight years and an average age of 6.8 years old. For each child, we sealed four permanent molars (totaling 128 teeth). The study group was divided into sub-groups. Sub-group A was represented by 64 first permanent molars which underwent dental sealing procedures with composite resin-based fissure sealant, Helioseal F™, and sub-group B was represented by 64 first permanent molars which underwent dental sealing procedures with glass carbomer cement, GCP Glass Seal™. The sealants were assessed clinically at 6, 12, 18, and 24 months. Results: The 6-month follow-up evaluation showed no statistically significant differences between the two materials neither regarding sealant retention nor new carious lesions formation (p > 0.05). At the 12-month recall, 57 molars had good retention (89.06%) from sub-group A and 44 molars (68.75%) from sub-group B; there was a statistically significant difference (p = 0.0187) between the two treatment choices only regarding material retention. At the last recall after 2 years, sub-group A had a higher number of molars with perfect sealing (47–73.43%) and 8 molars (12.5%) with new caries lesions and sub-group B had 23 (35.93%) molars with perfect sealing and 15 molars (23.44%) with new caries lesions; there was a statistically significant difference (p < 0.0001) between the two treatment choices only regarding material retention. Conclusions: The glass carbomer retention is very inferior to the resin-based material. The glass carbomer sealant was effective in preventing new caries development, comparable with the conventional resin-based sealant.

Efficacy of Ozone Pretreatment on Fissure Sealant Adaptation and Retention

ABSTRACT Pit and fissure sealants (PFSs) are the optimal treatment options to prevent occlusal caries. The aim of this in-vitro study was to evaluate the effect of ozone pretreatment on dental PFS retention when applied before or after acid etching. The retention of the PFSs was tested by microtensile bond strength test, scanning electron microscope (SEM) analysis, and microleakage evaluation. The present study found that sealant application with ozone pretreatment at a concentration of 60–80 µg/mL for 40 seconds, especially when used after acid etching, resulted in significantly less microleakage formation and better sealant penetration than traditional sealant application; however, it had no significant effect on bond strength.

Clinical evaluation of hydrophobic and hydrophilic pit and fissure sealants among 7-10 year old school children: a split mouth study design

Introduction: The study was done to compare the effectiveness of hydrophobic and hydrophilic pit and fissure sealant retention among 7-10 year old school children. Material and Methods: The present split mouth randomized trial was conducted on the occlusal surfaces of permanent first mandibular molars to compare and assess the retention along with other outcome variables like colour match, marginal discolouration, marginal adaptation, anatomic form, postoperative sensitivity, caries formation and surface roughness properties of Hydrophobic and Hydrophilic pit and fissure sealants at 3rd and 6th month. The data was compiled and analyzed using SPSS software and results were generated. Results: In the present study among the 50 restorations in the hydrophobic pit and fissure sealants (Group I), 48 (96%) restorations were retained at the end of third month and 45(90%) were retained at the end of sixth month. Among the 50 restorations in the hydrophilic pit and fissure sealants (Group II), 49(98%) restorations were retained at the end of third month, and 46(92%) at the end of sixth month were retained. There was no significant difference in the number of completely retained restorations at the end of six months (p = 1.00) among both the groups. The assessment of all the other outcome variables between both the interventions showed that the difference was not statistically significant. Conclusion: The study concluded that the hydrophilic pit and fissure sealant was similar to the hydrophobic pit and fissure sealant in terms of retention, colour match, marginal discolouration, marginal adaptation, anatomic form and surface roughness properties with.

Effect of Enamel Pre-etching with Sodium Hypochlorite Deproteinisation and Bonding Agent on Retention and Microleakage of Pit and Fissure Sealants: An In-vitro Study

Introduction: Sealants have proved to be one of the easiest methods of caries prevention in young permanent teeth, the placement of which is very technique sensitive. The non-invasive method of pretreating the enamel surface by deproteinising it with 5.25% sodium hypochlorite (NaOCl) for 60 seconds prior to etching has proven to be a promising method for improving retention and reducing microleakage of sealant. Aim: To evaluate the effect of enamel pre-etching with sodium hypochlorite deproteinisation and bonding agent on retention and microleakage of pit and fissure sealants. Materials and Methods: This in-vitro experimental study was conducted in Department of Paediatric and Preventive Dentistry at Annoor Dental College, Muvattupuzha, Kerala and Nanotechnology Lab at Amrita Institute of Medical Science. Freshly extracted Intact permanent maxillary and mandibular 20 third molars and 20 premolars mounted on acrylic blocks were divided into 4 groups containing 5 teeth in each group. Molars and premolar were taken for assessing the rate of retention and microleakage, respectively. Teeth in Group 1 were subjected to acid etching only, Group 2 were deproteinised prior to acid etching, Group 3 were subjected to acid etching followed by bonding and Group 4 were subjected to deproteinisation, etching and bonding. Then, all teeth were sealed with pit and fissure sealant and underwent thermocycling in artificial saliva bath for evaluation of sealant retention and microleakage. After thermocycling, retention was assessed on molar by one pre-calibrated blinded examiner by passing a 0.5 mm diameter probe along the margins of the sealant placed to verify integrity, failure, or loss of continuity based on Simonsen’s criteria (1989). To assess microleakage, premolar samples were immersed in rhodamine B, sectioned longitudinally, and examined under a stereomicroscope for assessment of microleakage. Collected data were statistically analysed using Chi-square and Mann-Whitney u test. Results: The results showed 100% retention for teeth in Group 2a, Group 3a, Group 4a, while partial sealant loss was present in 3 teeth from Group 1a. The differences between the groups for retention was statistically significant (p=0.014). In the case of microleakage, Group 3b showed more microleakage and group 4b showed least microleakage and the difference between them was statistically significant (p=0.009). Conclusion: Deproteinisation and use of bonding agent increases retention of the pit and fissure sealants. However, deproteinisation is a more effective method to control microleakage when compared to bonding agent. Thus, it can be considered as an effective method for pretreating enamel surface before sealant placement.

Clinical Comparison of Fissure Sealants Retention Following Preparation with Seventh Generation Bonding Agent with Prior Etching and Conventional Acid Etch and Bond System (fifth Generation)

Introduction: Fissure sealant therapy is a preventive method relied on covering pits and fissures to prohibit bacteria from settling on tooth and producing acid, which cause tooth demineralization. The benefits of caries prevention could only be achieved when the sealants remain intact for a long time, thus long-lasting retention is mandatory. Despite recently achieved improvement in sealant quality, their retention in long course remains a challenging issue in dentistry. The purpose of our study was to compare the clinical efficacy of sealants after using seventh generation adhesive and additional etchant material with fifth generation bonding agent. Materials and Methods: In this randomized clinical trial, 40 patients in the age group of 7 to 12 years were randomly selected. All participants had a pair of sound first permanent molar in the mandible, which need fissure sealant therapy. For each patient, one tooth was treated with seventh generation bonding and separate etching material, and the counterpart tooth had undergone the fifth generation bonding system. A pediatric dentist did exert 6 and 12-mounth follow ups. Results: In 38 of 40 patients, who completed 6-month follow-up, the success rate of seventh generation adhesive was 84.2% and in the fifth generation group it was 76.3%. At 12-month follow-up, 36 patients were referred and success rate of fifth generation bonding was 52% and it was 36% in seventh generation adhesive. According to fisher test, the difference between two groups was not statistically significant. Conclusion: This study depicted that fissure sealant retention was equal after 6 and 12 months in both methods.

Influence of Isolation Methods on Retention of Pit and Fissure Sealants in Young Permanent Teeth based on Simonsen’s Criteria: A Randomised Clinical Trial

Introduction: Pit and Fissure Sealants (PFS) are chemically-active liquid materials that are introduced into the occlusal surface of caries-susceptible teeth. These form a micro mechanically bonded, protective layer preventing access to caries-producing bacteria, from rest of the oral environment. Aim: To evaluate the retention of PFS placed on young permanent teeth using two isolation methods. Materials and Methods: This clinical study was carried out in the Department of Paediatric and Preventive Dentistry, at Narayana Dental College and Hospital, Nellore, Andhra Pradesh, India. One hundred Permanent First Molars (PFM) from 25 healthy, cooperative children in the age group of 6-9 years were assigned by block randomisation into two groups (isolation type); each group containing the upper and lower PFMs of the right and left side receiving two different treatment modalities (split-mouth design). In Group I (n=50 teeth), the teeth received sealant with rubber dam isolation, and in Group II (n=50 teeth), with cotton roll isolation. The sealant was applied to all the PFMs as indicated. All the teeth were evaluated using Simonsen’s criteria at regular intervals of 3, 6, and 12 months. The data collected were subjected to statistical analysis using the SPSS statistical package (version 17) and statistical significance was set at 0.05. The difference in the retention of PFS with the two isolation methods was analysed using the Chi-square test. Results: After 12 months, the marginal integrity rate for sealants placed with a rubber dam and cotton roll isolation were 75% and 64%, respectively. The results were better in Group I than in Group II, although there were no statistically significant differences with respect to marginal integrity, discolouration, and anatomical failure. Conclusion: Retention of PFS in young permanent teeth was better with rubber dam than cotton rolls for isolation, though the results were not statistically significant.

Effect of preconditioning on retention of glass ionomer pit and fissure sealant: An in vivo 9-month study

Purpose: Caries prevention using fissure sealants is directly proportional to their retention. This in vivo study evaluated the effect of preconditioning on retention of glass ionomer (GI) fissure sealant, in maxillary and mandibular primary and permanent teeth. Subjects and Methods: Two hundred and forty teeth in 30 children of 6-8 years age range were involved. In all participants, the second primary and the first permanent molars in each quadrant were investigated following split-mouth design; so that, selected teeth in the right side had their pits and fissures conditioned before GI sealant application (Group A: n = 120 teeth). In the left side, however, the same sealant was applied without preconditioning (Group B: n = 120). According to Simonsen's sealant retention criteria, clinical assessment was performed at 3, 6, and 9 months. Data were gained then statistically analyzed using Chi-square test. Results: A significant difference (P ≤ 0.05) was evident between both groups at the three assessment intervals, with better sealant retention in preconditioned group. Although no significant difference appeared between primary and permanent teeth, maxillary teeth were significantly better in sealant retention than mandibular ones. Conclusions: Preconditioning enhanced GI sealant retention, more durable caries prevention can be thus provided easily with low cost.

Retention of Various Pit and Fissure Sealants in Deciduous Teeth. A Systematic Review

Background: Dental caries is one of the most prevailing oral health diseases in children. Most of these dental caries occur in the deep pits and fissures. Pit and fissure sealants have been traditionally used for preventing dental caries. These are the materials which fill the fissures and making it self-cleansable. Objectives: To assess the retention rate of various pit and fissure sealants used in deciduous teeth Intervention: Pit and fissure sealants Results: A preliminary search yielded a total of 153 studies through Google scholar and search strategy used in PubMed. 7 articles giving 11 estimates were included for qualitative synthesis. All materials were light cured. Retention rate of fluoride releasing sealants and ACP sealants were superior to other sealants. Conclusion: Pit and fissure sealants have a good retention in primary dentition. Sealants are very well accepted and prove to be effective in preventing occlusal caries found in the large number amongst children. Use of sealants in primary dentition will surely prevent the damage to erupting permanent dentition due to developing caries in the former.

Comparison of Color, Coverage and Caries (CCC) Evaluation System and Simonsen’s Criteria in Assessing the Retention of Pit and Fissure Sealants

Retention and effectiveness of pit and fissure sealants placed with or without bonding agent in young permanent teeth: A randomized clinical trial with a year follow-up.

The aim of this study is to evaluate the clinical efficacy of pit and fissure sealants (PFS) placed on young permanent teeth with or without the application of the bonding agent. A. After 12 months, the clinically acceptable retention rates for PFS placed with and without bonding agent were 80% and 72%, respectively. No statistically significant difference was observed in relation to marginal integrity, marginal discoloration, and anatomic form among the PFS placed with and without bonding agent (Ps > 0.05). Sealant application with bonding agent showed an increased retention rate than without the use of a bonding agent. However, an additional step of bonding may be excluded in children, as it did not show any statistically significant difference in clinical retention rate compared to PFS application without bonding.
