The study arms are RM-GIC (FUJI II LC), CN + adhesive system, and CN + retentive groove. The study included 25 restorations per arm. Follow-ups were performed at 1 week, 3, 6, and 9 months after the application of the restorations.

The average increase after 9 months was 0.06 and 0.34 for PI and PD, respectively, with that of PD being significant. It was also noted that the percentage of positive BOP sites increased at the 1-week follow-up for all study groups and afterward dropped to near preintervention values at the 3-month and later follow-ups.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>The two ion-releasing materials Cention N and RM-GIC have a comparable and clinically acceptable effect on the gingival tissue when restoring NCCLs. The combined effect of the gingival retraction cord and the rubber dam clamp on the periodontal tissues might be more important to consider, especially in relation to the probing depth. Future long-term studies are needed to evaluate the effect of Cention N on the subgingival biofilm in comparison with nonion-releasing restorative materials, and subsequently, its effect on gingival inflammation.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Clinical Trial Registration</h3>\u0000 \u0000 <p>This clinical trial was registered in clinicaltrial.gov clinical registry under protocol #NCT05593159.</p>\u0000 </section>\u0000 </div>","PeriodicalId":10203,"journal":{"name":"Clinical and Experimental Dental Research","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cre2.70025","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142435503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For diagnosis, wearable devices that use sounds as biomarkers can be applied to provide the necessary information. Human beings emit various verbal and nonverbal sounds, making it challenging to identify bruxism-induced sounds. We wanted to investigate whether the acoustic emissions of different oral behaviors have distinctive characteristics and if the placement of the transducer has an impact on recording the sound signals.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Material and Methods</h3>\u0000 \u0000 <p>Sounds from five oral behaviors were investigated: jaw clenching, teeth grinding, reading, eating, and drinking. Eight transducers were used; six were attached to the temporal, frontal, and zygomatic bones with the aid of medical tape, and two were integrated into two commercial earphones. The data from 15 participants were analyzed using time-domain energy, spectral flux, and zero crossing rate (ZCR).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>In summary, all oral behaviors showed distinct characteristic features except jaw clenching, though there was a peak in the recording, possibly due to tooth tapping, before its expected onset. For teeth grinding, the transducer placement did not have a significant impact (<i>p</i> &gt; 0.05) based on energy, spectral flux, and ZCR. For jaw clenching, the transducer placement had an impact with regard to spectral flux (<i>p</i> &lt; 0.01). For reading and eating, the transducer placement had a significant impact with regard to energy (<i>p</i> &lt; 0.05 for reading, <i>p</i> &lt; 0.01 for eating), spectral flux (<i>p</i> &lt; 0.001 for reading, <i>p</i> &lt; 0.01 for eating), and ZCR (<i>p</i> &lt; 0.001 for both reading and eating). For drinking, the transducer placement only had a significant impact with regard to ZCR (<i>p</i> &lt; 0.01).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>We were able to record the sounds of various oral behaviors from different locations on the head.
