Nifedipine-induced gingival enlargement around dental implants: a clinical report.
Calcium channel-blocking agents are used extensively for the management of cardiovascular conditions, including angina pectoris, coronary artery spasm, cardiac arrhythmias, and hypertension. Gingival overgrowth around natural teeth has been previously reported in the literature with patients taking calcium channel-blocking agents. This clinical report describes hyperplasia of tissues around titanium dental implants in a patient taking Nifedipine along with the multiphasic approach to treating this medication-induced hyperplasia of the peri-implant tissues.

The microbiota of the peri-implant region in health and disease.
The subgingival microflora associated with dental implants has been shown to be similar to that associated with natural teeth. Like the natural tooth, a dental implant may be susceptible to a plaque-induced gingivitis which may progress to peri-implantitis. A similarity exists between the microbial flora around failing implants and organisms classically associated with periodontal disease. The same anaerobic gram-negative organisms are found in periodontitis and peri-implantitis. The periodontium must be in a healthy state before the placement of dental implants and constantly monitored while implants are in function for early detection of potential periodontal and/or prosthodontic problems. The relationship between the microbial flora around dental implants and peri-implantitis is discussed and recommendations are presented to improve the efficacy of dental implants.

Connective tissue grafting for improved implant esthetics: clinical technique.
The subepithelial connective tissue graft can be used to enhance the esthetic appearance and gingival contour of the peri-implant tissues. A technique is described and illustrated to create a soft-tissue root prominence and mask the grayish color that may be present as a result of a thin facial alveolar bony plate and/or thin labial attached gingival tissue over dental implants.

Linear tomography in conjunction with pantomography in the assessment of dental implant recipient sites.
Tomography provides a three-dimensional unobstructed and anatomically accurate picture of the region being viewed. Tomography is a radiographic technique in which a "slice" or section of a given internal body structure is imaged in a pre-determined plane. The advantage of utilizing a tomographic evaluation along with a pantomographic survey is that the clinician may examine the exact position or depth in all three planes of visualization. This radiographic modality can also reveal the quality and quantity of alveolar bone in a pre-determined implant site. This information would allow the clinician better to diagnose, plan treatment, and place dental implants more precisely. Therefore, the utilization of laminar or computerized tomography along with pantomography for more precise visualization and accurate measurement of available alveolar bone of the buccal-lingual and labial-palatal perspective will be discussed and illustrated.

The use of the subepithelial connective tissue graft to enhance both the aesthetics and periodontal contours surrounding dental implants.
The subepithelial connective tissue graft is a gingival grafting plastic surgery procedure that can be used to enhance the aesthetic and gingival contour of the periodontium around dental implants. This technique is described and illustrated to create a soft-tissue root prominence and mask the grey color penetrating the thin labial attached gingival tissues over dental implants.

The use of free gingival soft tissue to improve the implant/soft-tissue interface.
Various techniques for the placement of different types of dental implants have evolved to the point where predictable bone-to-implant integration occurs if proper surgical technique is followed. The soft-tissue adaptation to the implant abutment is the first line of defense to prevent the development of peri-implantitis and subsequent bone loss. Given that there is a tenuous protective seal around dental implants, the rationale for soft-tissue augmentation around dental implants to provide an improved, tightly adapted implant/soft-tissue interface definitely exists.

Mental neuropathy associated with malignant disease: a case report.
In the current report, we emphasize that mental neuropathy is often a sign of progressive or recurrent malignant disease, despite normal results of a mandibular radiograph in a diagnostic evaluation.

Bone regeneration and tissue acceptance of human fascia lata grafts adjacent to dental implants: a preliminary case report.
The biologic principle of guided tissue regeneration (GTR) has been studied extensively in hopes of regenerating alveolar bone. Various materials have been utilized as regenerative membranes; however, all materials have disadvantages, and the ideal membrane material is yet to be identified. In this case report, human freeze-dried fascia lata strips were used as a regenerative barrier membrane in conjunction with the placement of endosseous root implants and demineralized, freeze-dried bone allograft. The major advantage in the use of human fascia lata for guided tissue regeneration is that a second procedure to remove the material is not necessary, and the fascia is accepted by the surrounding tissues without complication. There is acceptance of four endosseous root-form dental implants that were immediately placed into fresh extraction sockets and covered with demineralized freeze-dried bone allograft (DFDBA), with human freeze-dried fascia lata used to serve as a biocompatible, collagenous, regenerative augmentation membrane over the dental implants. The biologic concept of GTR is clinically applied to increase the dimensions of the edentulous, maxillary alveolar ridge with use of human freeze-dried fascia lata barrier membranes.

Bacterial penetration of gingiva in the adult beagle dog with periodontitis.
Invasion of gingival tissues by bacteria is thought to be a major factor in development of periodontal lesions. Morphologic studies have revealed bacteria within the pocket epithelium, gingival connective tissues, alveolar bone, and oral epithelium. The current studies are intended to determine whether they are present in healthy and diseased tissues and to identify the microbial source. Five beagle dogs with naturally occurring periodontitis were fed a soft diet. Two quadrants of the dentition of each dog were cleaned regularly and health maintained while others were allowed to develop further disease. After 4 weeks, samples of gingiva were removed both prior to and after the animals were sacrificed by perfusion fixation attempting not to introduce microorganisms. The identical samples were examined by light and scanning electron microscopy for numbers and location of organisms. Their numbers were greater in diseased than in healthy tissues. Furthermore, the quantity was greater in samples taken prior to perfusion fixation than after such treatment, especially in the oral epithelium. The results suggest that normally there are some microorganisms present within the periodontal tissues and that their numbers are greater in diseased tissues. However, the data also indicated that significant numbers may be introduced into the tissues during sampling of unfixed tissues.

Medication-induced gingival enlargement: a clinical review.
This review discusses the etiology and treatment of gingival hyperplasia. It cites evidence that medications such as phenytoin, an anticonvulsant; cyclosporine, an immunosuppressant; and numerous calcium channel blocking agents have been shown clinically and histologically to produce analogous gingival enlargements. A multiphasic approach to treating disfiguring gingival hyperplasia through mechanical and chemical plaque control, in conjunction with the surgical removal of the hyperplastic tissue, is discussed.
