“…55 From a series of experiments, it became clear that a regular etch pattern with increased surface roughness is possible at the very base of pits and fissures, 54 thus providing the basis for adhesive linkage. Therefore, mechanical removal of aprismatic enamel (by enameloplasty or fissurotomy), though favourable in some cases, 56 would seem dispensable, 35 whereas etching (using etch-and-rinse systems) is regarded as essential for adequate mechanical adhesion and minimising loss of retention. 55, 56 …”

Resin infiltration of deproteinised natural occlusal subsurface lesions improves initial quality of fissure sealing

et al. 2017

The aim of this ex vivo study was to evaluate the infiltration capability and rate of microleakage of a low-viscous resin infiltrant combined with a flowable composite resin (RI/CR) when used with deproteinised and etched occlusal subsurface lesions (International Caries Detection and Assessment System code 2). This combined treatment procedure was compared with the exclusive use of flowable composite resin (CR) for fissure sealing. Twenty premolars and 20 molars revealing non-cavitated occlusal carious lesions were randomly divided into two groups and were meticulously cleaned and deproteinised using NaOCl (2%). After etching with HCl (15%), 10 premolar and 10 molar lesions were infiltrated (Icon/DMG; rhodamine B isothiocyanate (RITC)-labelled) followed by fissure sealing (G-ænial Flo/GC; experimental group, RI/CR). In the control group (CR), the carious fissures were only sealed. Specimens were cut perpendicular to the occlusal surface and through the area of the highest demineralisation (DIAGNOdent pen, KaVo). Using confocal laser-scanning microscopy, the specimens were assessed with regard to the percentage of caries infiltration, marginal adaption and internal integrity. Within the CR group, the carious lesions were not infiltrated. Both premolar (57.9%±23.1%) and molar lesions (35.3%±22.1%) of the RI/CR group were uniformly infiltrated to a substantial extent, albeit with significant differences (P=0.034). Moreover, microleakage (n=1) and the occurrence of voids (n=2) were reduced in the RI/CR group compared with the CR group (5 and 17 specimens, respectively). The RI/CR approach increases the initial quality of fissure sealing and is recommended for the clinical control of occlusal caries.

“…Furthermore, saliva contamination after the etching procedures can also compromise adhesion [12]. Therefore, alternative methods to acid etching, such as enameloplasty, an air-polishing system and laser treatment have been proposed for preparing fissures for sealant retention [13, 14].…”

The clinical effects of laser preparation of tooth surfaces for fissure sealants placement: a systematic review and meta-analysis

et al. 2019

Background This systematic review aimed to assess the clinical effects of laser preparation compared to other types of chemical or mechanical preparation of tooth surfaces used in fissure sealant placement. Methods A systematic literature search was conducted up to January 2019, through Pubmed, Scopus, Medline/EMBASE via OVID and the Cochrane library. Only randomized clinical trials were included. Results Five studies were included in the systematic review and three were included in the meta-analysis. All the studies used acid-etching as a comparator to lasers. All the included studies were rated as having an overall high risk of bias introduced by performance bias. Three studies assessed the clinical effects of fissure sealants placed by acid or laser etching, one compared acid etching versus laser combined with acid etching and one investigated the influence of lasers on the objective and subjective parameters of stress during sealant application in children. The meta-analysis showed no significant difference between laser preparation and conventional acid-etching preparation at 3- ( P = 0.08), 6- ( P = 0.49), and 12-month ( P = 0.87) follow-ups. One study reported that laser preparation as an adjunct to acid-etching enhanced the retention rate. No significant difference in the incidence of caries was reported. And no significant differences were found in heart rates, oxygen saturation or degree of the patient dental anxiety between acid-etching and laser preparation. Conclusion The present limited evidence suggests that lasers could be an effective pretreatment method. The retention rate was similar to that of conventional acid etching. However, the included studies had an overall high risk of bias and more rigorously designed research is needed.

“…It is widely known that caries preventive treatment is helpful for dental health [26,27]. Pit and fissure sealant therapy may reduce the prevalence of dental caries from 11% to 51% [28].…”

Self-reported oral health habits, knowledge and conditions of schoolchildren and adolescents in mainland China

To determine the oral health habits, knowledge and conditions of students in China and investigate the impact of associated factors. A self-reported online questionnaire was distributed through social networks in mainland China to assess the oral health habits, knowledge, and conditions of students aged 6–20 years attending primary, middle, and high schools. Factors potentially associated with oral health, such as oral health habits of their parents, family education level, and economic regions, were analyzed using McNemar’s and Chi-square tests. Within one month, 5561 valid questionnaires were retrieved from all 31 provinces or equivalent regions in mainland China. The results showed that 46.9% of students suffered from bleeding when brushing their teeth, while only 11.8% reported professional teeth cleaning at a dental clinic. Soda beverages were widely consumed among them (75.4%). A significant minority of students brushed their teeth less than twice daily (22.8%) and for about 2 minutes each time (19.3%). Only 21.9% of the students had preventive oral health care. Students’ toothbrushing habits and knowledge about interdental cleaning tools were associated with parental habits (p < 0.001). Overall, students from families with higher educational backgrounds and eastern China had better oral health habits, knowledge, and conditions. There is a need to pay more attention to gingival health and caries prevention among schoolchildren and adolescents in mainland China. Improving parental oral hygiene habits could have a positive impact on the oral health of students. Further research on oral health among students is needed in the middle and western regions of China.
