10-Minute Ebd: Are Neoplasms A Risk Factor For Peri-Implantitis?, Farah Safieddine Bs, Naama Sleiman Ms, Phd, Melanie E. Mayberry Dds, Ms-Hcm

The Journal of the Michigan Dental Association

This 10-Minute EBD column explores the potential association between neoplasms and the risk of peri-implantitis in patients with dental implants. A case study involving a patient with a history of an ossifying fibroma raises questions about the impact of neoplasms on implant success. The literature search, conducted on PubMed, reveals relevant insights. The evidence suggests that ossifying fibromas, particularly with augmentation, may pose a risk for peri-implantitis. However, the direct causative relationship between neoplasms and peri-implant pathology remains unclear. Other risk factors such as periodontitis, foreign bodies, and augmentation procedures are also discussed in the context of implant complications.

Different Irrigant Activation Techniques In Removing Dentin Debris: An In-Vitro Study, Maya T. Eter, Roula S. Abiad

BAU Journal - Creative Sustainable Development

During endodontic treatment, the efficiency of irrigation depends on two criteria: the antimicrobial and dissolving properties of the irrigation solution and the delivery system used that dictates the flushing action of the irrigant and consequently enable it to reach complex areas. The purpose of this in-vitro study was to compare the cleaning efficiency of EDDY sonic activation with needle irrigation and passive ultrasonic activation regarding elimination of dentin debris. Forty single rooted extracted teeth were instrumented and then were split in bucco-lingual direction. A longitudinal groove was performed in the inner surface of one root half of each tooth.

Management Of Severe Localized Periodontal Destruction Associated With A Cemental Defect: A Case Report, Nik Madihah Nik Azis, Nurulhuda Mohd

Journal of Dentistry Indonesia

This case involved the management of a possible cemental tear, which resulted in poor response to nonsurgical periodontal therapy. This case was managed by exploratory surgery, along with the intention to surgically reduce the periodontal pocket. Exploratory surgery revealed a localized cemental defect. The periodontium healed with pocket closure after exploratory surgery and open-flap debridement. The difficulty in clinically diagnosing a localized periodontal destruction and the lack of consensus on managing these cases were highlighted. The possibility of an undiagnosed cemental defect in a tooth with localized periodontitis should be considered in cases not responding to periodontal therapy.
