1/9. Subgingival plaque and loss of attachment in periodontosis as observed in autopsy material.Histologic sections from six autopsy cases which from a clinical point of view fitted into the criteria of periodontosis were examined with the aim at evaluating the role of subgingival plaque in the etiology of the loss of attachment in this condition. The following pertinent observations were made: 1. The subgingival plaque in most instances was not calcified to form calculus. 2. The thickness of the subgingival plaque varied between 20 and 200 mu (0.02-0.2 mm). 3. Where loss of attachment had taken place, the distance from the most apical part of the subgingival plaque to the most apical point of the epithelial cuff varied between 0.2 and 1.1 mm; this distance was never found to be more than 1.1 mm. This would indicate a cause and effect relationship, the plaque being the obvious cause. 4. There was very severe chronic inflammation in the soft tissue bordering upon the plaque with resulting collagenolysis. 5. The cellular infiltration and the collagenolysis may be limited to a zone of 1 to 2 mm in the immediate vicinity of the plaque. Between the inflamed area and the surface of the gingivae buccally and lingually there may be a fairly wide zone of healthy tissue which hides the symptoms of inflammation from being observed on a clinical examination. In turn this could leave the clinician with the impression that attachment has been lost and bone resorbed because of degenerative changes. The following conclusions can be made: In these six cases of "alveolar bone loss vastly out of proportion to what one would expect from the local etiologic factors in the patient at that age" there was no morphologic evidence that degenerative changes were responsible for the loss of attachment. On the contrary inflammatory changes induced by the subgingval plaque dominated the histopathologic picture.- - - - - - - - - - ranking = 1keywords = gingival (Clic here for more details about this article) |
2/9. The influence of transseptal fibers on incisor position and diastema formation.Transseptal fibers are a part of the gingival group of fibers of the periodontal membrane, and they are very tough and resistant. They form a chain from tooth to tooth which, provided that it remains intact and is sufficiently strong to resist displacing muscular pressures, will preserve the contacts between the teeth throughout the arch. If the continuity of the chain is interrupted, the balance of the forces acting upon the teeth on either side of the break is upset and considerable displacements can occur. Maxillary median diastemas are classified as "simple" or "persistent" according to their etiology, and an operation to clear the upper midline suture of transeptal fibers is described as an essential part of the treatment of persistent upper median diastema.- - - - - - - - - - ranking = 0.125keywords = gingival (Clic here for more details about this article) |
3/9. Drug-induced gingival overgrowth: a case with auto-correction of incisor drifting.Drug-induced gingival overgrowth is an iatrogenic clinical condition, which affects a proportion of patients medicated for conditions such as hypertension, epilepsy and the prevention of organ transplant rejection. Clinical manifestation can vary in severity from minor problems to complete coverage of the standing teeth. Drifting of teeth can also occur, producing further aesthetic and functional problems for the patient. This report documents a case of a renal transplant patient in whom drifting of the upper incisor teeth spontaneously resolved following surgical reduction of the overgrown gingivae. Clinical issues relating to the management of gingival overgrowth are also discussed.- - - - - - - - - - ranking = 13.139071793676keywords = gingival overgrowth, gingival, overgrowth (Clic here for more details about this article) |
4/9. Pathologic migration--spontaneous correction following periodontal therapy: a case report.Periodontal disease is often associated with pathologic migration, which becomes an esthetic concern. A 17-year-old girl developed increasing gaps among her maxillary incisors. She had gingival enlargement in the palatal maxillary anterior region. The central incisors had pathologically migrated, resulting in a 2-mm diastema. Periodontal treatment was planned and completed. Following periodontal treatment, there was "spontaneous" repositioning of the central incisors. The 6-month follow-up revealed no change or deterioration of the periodontal condition. The patient was referred for orthodontic closure of the remaining diastema between the central and lateral incisors.- - - - - - - - - - ranking = 0.125keywords = gingival (Clic here for more details about this article) |
5/9. Orthodontic movement into bone defects augmented with bovine bone mineral and fibrin sealer: a reentry case report.Periodontal disease can lead to migration of anterior teeth with the presence of infrabony defects. This creates the opportunity for treating such patients with a combined orthodontic-periodontic treatment. In the presented clinical case, an adult periodontal patient with extrusion of the maxillary central incisors and an infrabony defect on their lingual aspects was treated. During the surgical procedure, the bone defects were augmented with a combination of porous bovine bone mineral (Bio-Oss) and a fibrin-fibronectin sealing system (Tissucol). Ten days after surgery, the active orthodontic treatment started, and the teeth were intruded and realigned, moving the roots into the defects. After 6 months, the orthodontic appliances were removed and the teeth were retained by means of a resin-bonded splint. At this time, reduction in probing pocket depth and gingival recession was detected. Twelve months after the initial surgery, a reentry procedure was performed, showing complete filling of the predisposing defects with the presence of bone-like hard tissue. These clinical results suggest that teeth can be successfully moved and intruded into bone defects previously augmented with bovine bone substitute and fibrin glue. During the orthodontic treatment, this combined augmentation material was able to be replaced by bone-like hard tissue. At the end of the therapy, an improvement in esthetics and periodontal health status was registered.- - - - - - - - - - ranking = 0.125keywords = gingival (Clic here for more details about this article) |
6/9. Interdental papilla augmentation procedure following orthodontic treatment in a periodontal patient.BACKGROUND: The absence of the interdental papilla is a situation that may alter patients' esthetics. Recession of interproximal gingival tissues may be a consequence of periodontal disease, but in some cases it may also be a consequence of periodontal therapy, as a result of surgical or non-surgical procedures. methods: The authors present a new multidisciplinary approach for the treatment of migrated maxillary incisors presenting infrabony defects, extrusion, and loss of the interdental papilla. RESULTS AND CONCLUSION: The proposed clinical protocol may reconstruct the interproximal soft tissue, with esthetic improvement of the papillary level, together with resolution of the periodontal defects.- - - - - - - - - - ranking = 0.125keywords = gingival (Clic here for more details about this article) |
7/9. gingival recession and pathologic migration due to an unusual habit.Various etiologies are implicated as causes of gingival recession and pathological tooth migration, most prevalent among these being the tissue destruction caused by periodontal pathogens. One of the least documented causes is a parafunctional habit, such as digit-sucking or sucking on objects like pencils, pens or toothpicks, all of which can lead to adverse effects on the dentition and the periodontal tissues resulting in midline diastema, alveolar bone loss, gingival recession, mobility, and ultimately tooth loss. This case report describes the periodontal injury caused by an unusual habit of placing a coin between the mandibular anterior teeth. The potential effects of this habit on the dentition and periodontium are discussed; the preventive measures to be taken and the outline for the management of such cases, to ensure periodontal health of the patient are dealt with in this report.- - - - - - - - - - ranking = 0.25keywords = gingival (Clic here for more details about this article) |
8/9. Long-term uncontrolled hereditary gingival fibromatosis: a case report.Hereditary gingival fibromatosis (HGF) is a rare condition characterized by varying degrees of gingival hyperplasia. Gingival fibromatosis usually occurs as an isolated disorder or can be associated with a variety of other syndromes. A 33-year-old male patient who had a generalized severe gingival overgrowth covering two thirds of almost all maxillary and mandibular teeth is reported. A mucoperiosteal flap was performed using interdental and crevicular incisions to remove excess gingival tissues and an internal bevel incision to reflect flaps. The patient was treated 15 years ago in the same clinical facility using the same treatment strategy. There was no recurrence one year following the most recent surgery.- - - - - - - - - - ranking = 3.064845298946keywords = gingival overgrowth, gingival, overgrowth (Clic here for more details about this article) |
9/9. Prosthodontic treatment for a patient with advanced hydantoin-associated gingival hyperplasia: a case report.A patient in whom gingival hyperplasia was caused by prolonged use of an anticonvulsant drug (hydantoin) is described. Advanced gingival hyperplasia and significant displacement of the remaining teeth caused severe damage, especially to the patient's appearance. It was not possible to cure the problems completely with routine periodontal treatment. It was decided to extract all the remaining teeth and restore function and esthetics early with complete dentures. Cephalometric analysis was used to determine the degree to which the teeth had drifted. During fabrication of the dentures, the analysis was very useful in deciding the position of the anterior teeth and checking the vertical dimension of occlusion.- - - - - - - - - - ranking = 0.75keywords = gingival (Clic here for more details about this article) |
