The loss of interproximal attachment, often accompanied by papilla loss, can lead to phonetic, functional, and esthetic challenges. However, existing literature provides limited data on treatment outcomes for interdental papilla reconstruction and root coverage. This technical case report presents a novel surgical approach utilizing labial mucosal vertical incisions and palatal marginal vertical incisions to facilitate creation of a partial-full-thickness (PFT) tunnel. Then, connective tissue grafts (CTGs), stabilized by supra-crestal sling (SCS) sutures, are used to support and coronally advance the soft tissue overlying the graft to obtain root coverage and enhance papilla height and volume. This technique optimizes blood supply and maximizes wound stability, resulting in significant papilla augmentation and complete root coverage. It is suggested that PFT tunnel preparation via labial mucosal vertical incisions and palatal marginal vertical incisions, combined with CTG stabilization via the SCS suture, has the potential to treat gingival recessions with deficient papilla in the maxillary esthetic zone.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"1-24"},"PeriodicalIF":0.0,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144612744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There was no occlusal trauma, hypersensitivity, or parafunctional habit. Clinically, there was 4mm GR on the facial surface, classified as Miller's Class I (RT1), with a probing depth of 1mm, without bleeding on probing. A partial thickness flap was reflected around the teeth to be grafted. The donor site (palate) provided a subepithelial connective tissue graft (CTG), as per the Langer and Langer protocol. A 2mm thick graft was harvested and surgically placed on the recipient side; the flap was then repositioned. The patient was evaluated after 6 months (GR: -0.5mm), twenty-seven years (GR: 1.0mm), and thirty-seven years (GR: 1.5mm). This was a successful long-term result. However, a relapse was noted, possibly exacerbated by orthodontic treatment associated with the thin overall phenotype in both arches.Conclusion: SCTG is a safe and effective modality for long-term root coverage, demonstrating tissue stability, thickness gain, and complete root coverage within six months after the procedure. A relapse of approximately 1.5 mm was noted on the facial surface after thirty-seven years.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"1-19"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144546735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This in-vitro study examined the effects of various manual sharpening diamond- coated cards (medium, fine, extra-fine) and synthetic stones (medium India, fine ceramic) on the roughness of Gracey 11/12 curette edges and instrumented root surfaces. All instruments were sharpened by a single operator using a standardized stationary instrument, moving stone (SIMS) technique. Root planing was then performed on mounted extracted teeth. Using optical profilometry, surface roughness was quantified. Results showed that fine grit abrasives produced smoother cutting edges and root surfaces compared to coarse grit abrasives (p < 0.05). Curettes sharpened with the extra-fine diamond card yielded the lowest roughness on both the instrument edge and the root surface. The orientation of the sharpening card influenced outcomes with a vertical orientation resulting in a significantly smoother edge than a horizontal orientation. Sequential sharpening, using fine then extra fine cards, further reduced edge and root roughness compared with using only a single fine grit. These findings highlight the importance of using extra-fine grit sharpening tools and proper sharpening technique to produce a smooth root surface.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144546736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, none of them are exempt from postoperative complications, particularly when dFGG is combined with TUN techniques. Most common complications include the re-epithelialization of the marginal graft, resulting in undesirable esthetic outcomes. This paper describes the modified orientation of the dFGG under the tunnel, with the lamina propria layer facing the tooth's root (inverted graft), aiming to minimize the risk of esthetic complications.Methods: 10 non-smoking patients with no comorbidities, presenting a total of 15 Miller class I/II (RT1) gingival recessions cases, were subjected to root coverage surgical treatment with the introduced technique (TUN+ inverted dFGG). After 6-months, each case was accessed using the root coverage esthetic score (RES).Results: Regarding soft tissue integration parameters, the score was 3 out of 3 for all cases. Mean amount of root coverage was 97%. 13 recession defects (86%) achievedcomplete root coverage. The mean RES was 9.6, ranging from 7 to 10. 13 recession defects (86%) achieved a RES of 10.Conclusions: The orientation of the dFGG under the tunnel, with the lamina propria layer facing the tooth's root (inverted graft), seems to present a promising aesthetic root coverage procedure and may be considered to minimize the risk of major esthetic complications when a dFGG is used under the TUN technique. Further studies are needed to address this proof of principle.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"1-23"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144546737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this investigation is to document the fracture toughness of a number of esthetic indirect restorative materials on the market and to provide recommendations for their application based on existing clinical and laboratory data sets.Methods: Fifty-six monolithic esthetic restorative materials were tested for fracture toughness. Monolithic zirconia materials were tested using the Single Edge Pre-Cracked Beam (SEPB) method, while glass ceramics and resin-ceramic hybrids were tested using the Single Edge V-Notch method (SEVN).Results: Fracture toughness values for monolithic zirconia correlated inversely with increasing yttria content. 3 mol % yttria-stabilized tetragonal zirconia polycrystal (3Y -MZ) had the highest fracture toughness range (5.55 - 5.64 MPa√m), followed by 4Y -MZ (4.02 - 4.15 MPa√m) and 5Y -MZ (2.43 - 2.70 MPa√m). For some 4Y -MZ and 5Y -MZ products, there was not a significant difference in toughness (p <0.05). Several lithium-based glass ceramics (LBC) had a similar fracture toughness (range of 2.46 - 2.68 MPa√m) to 5Y -MZ (p <0.05). Most LBCs had a fracture toughness range of 1.53 - 2.04 MPa√m, higher than that of other glass ceramics but less than that of 5Y -MZ (p<0.05). Results for resin-ceramic hybrids varied from 1.15 - 2.05 MPa√m, with none reaching the fracture toughness of the higher LBCs or 5Y -MZ (p <0.05).Significance: Clinicians should be aware of the fracture toughness of the materials they use and adjust their preparation parameters accordingly. As fracture toughness decreases, thickness of the resultant restoration should be increased to accommodate the decrease in fracture resistance.","PeriodicalId":94231,"journal":{"name":"The International journal of periodontics & restorative dentistry","volume":"0 0","pages":"1-26"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144546738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
