The present systematic review aims to evaluate the efficiency of Physics forceps over the conventional forceps for the extraction of a tooth. The study began with targeted electronic searches of MEDLINE, PubMed, Cochrane, Science Direct and Google Scholar databases. All selected articles were reviewed by four independent reviewers for eligibility. The Cochrane Risk of Bias tool was used to analyze the studies for bias. Due to heterogeneity of the selected studies, a meta-analysis of the current systematic review was not possible. A total of five studies were considered for the final analysis. The risk of bias showed high risk for all five included articles. Various parameters, such as fracture of the root, dry socket, healing, pain, postoperative infection, crown fractures, buccal bone fractures, extraction time, gingival and marginal bone loss, gingival laceration, bleeding and healing were assessed. Based on the data available, there is an insufficient quality of evidence to conclude the superiority of the Physics forceps over conventional forceps.

Dental biofilm plays a very crucial role in the etiopathogenesis of periodontal andperi-implant diseases. Over the past decade, tremendous research has been carried outto know the structure of biofilm and the mechanism by which it causes the destruction of supporting tissues of tooth or implant. Periodontal or peri-implant therapy usually begins with primarily removing thebiofilm and is considered as non-surgical mechanical debridement. Although scaling and root planing (SRP) is regarded as a gold standard for mechanical plaque debridement, various other means of biofilm removal have constantly been evolving. These may vary from different scaling systems such as vector systems to decontamination of pockets with LASER therapy. Nowadays, a new concept has emerged known as "guided biofilm therapy" (GBT). It is beneficial in removing the biofilm around the tooth and implant structures, resulting in better or comparable clinical outcomes than SRP. These results were substantiated with the reduction in the microbial load as well as the reduction in the inflammatory cytokines. This review will highlight the various aspects of GBT used in periodontal and peri-implant disease.

Aim: Biofilm bacteria show coordinated behavior with heterogeneous bacterial communities and complex three-dimensional structures. Biofilm formation on dental implants occurs in a manner similar to that of a natural tooth. Bacterial adhesion occurs after pellicle formation. Therefore, to reduce bacterial adhesion, the biomaterial surface can be modified, thereby lowering the scope of biofilm formation. This review aimed to understand the mechanism of biofilm formation; the most common microorganisms associated with a biofilm, nature of the bonds to the host tissue, and the methods to overcome biofilm formation and associated infectious diseases from dental materials and implants. Materials and Methods: A comprehensive literature search was conducted on published articles using internet search databases such as PubMed, EBSCO, Cochrane library, Embase, HMIC, Web of Science, Google Scholar, and Directory of Open Access using keywords such as biofilm, quorum sensing, implant-related biofilm formation, and biofilm control. Results: A total of 121 articles published from March 2007 to May 2020 were screened during the review process, of which only 33 articles were selected for this study. Surface roughness is directly proportional to bacterial aggregation. PEEK is a modified functional peptide nanoparticle-coated biomaterial that manifests antibacterial activity against gram-negative Escherichia coli and gram-positive Staphylococcus aureus. Conclusions: New strategies are to be followed to control biofilm-mediated implant infections. Clinicians should extensively adopt newer techniques to deal with biofilm-mediated therapeutic challenges.

The fibroma, also referred to as irritation fibroma, is by far the most common of the oral fibrous tumorlike growths. While the terminology implies a benign neoplasm, most if not all fibromas represent reactive focal fibrous hyperplasia due to trauma or local irritation. Although the term focal fibrous hyperplasia more accurately describes the clinical appearance and pathogenesis of this entity, it is not commonly used. We present a case report of oral fibroma in the left side of the buccal mucosa in 50 years old Saudi patient.

Lipoma is a common tumor of soft tissue. Its location on the oral mucosa is rare, representing 1% to 5% of benign oral tumors although it is the most mesenchymal tumor of the trunk and proximal portions of extremities. Lipoma of the oral cavity may occur in any region. The buccal mucosa, tongue, and floor of the mouth are among the common locations. The clinical presentation is typically as an asymptomatic yellowish mass. The overlying epithelium is intact, and superficial blood vessels are usually evident over the tumor. Other benign connective tissue lesions such as granular cell tumor, neurofibroma, traumatic fibroma and salivary gland lesions (mucocele and mixed tumor) might be included in differential diagnosis. We present a case report of oral lipoma in the left side of the lower lip in 18 years old Saudi patient.
