Gingival grafting in periodontal practice: results of 103 consecutive surgeries in 82 patients.

A consecutive series of 103 surgeries in 82 patients was studied from the normal clinical population of a periodontal specialty practice. Four different techniques were employed: free gingival grafts, free connective tissue grafts, pedicle flaps, and combined techniques. Gingival augmentation using free gingival grafts was the most predictable, with 100% of cases showing a gain of > or = 3 mm.

Localized periodontitis as a long-term effect of oral piercing: a case report.

Recent years have seen a dramatic increase in the number of published articles on short-term complications of oral piercing, possibly reflecting an increase in the popularity of this practice. Long-term effects of oral piercing, however, have had minimal documentation. This case report of a 28-year-old woman with piercing of the tongue and lower lip demonstrated localized severe periodontitis as a destructive long-term outcome related to oral piercing.

Investigations on the influence of helminth parasites on vaccination of chickens against Newcastle disease virus under village conditions.

Prevalence studies have shown that almost 100% of free-range chickens are infected with a wide range of parasites. The infections are mostly subclinical in nature, resulting in production losses and occasionally mortality. Newcastle disease (ND) on the other hand, results in high mortality rates during epidemics.

Myospherulosis complicating cortical block grafting: a case report.

Background: Myospherulosis of the oral cavity is an inflammatory, granulomatous lesion historically associated with the use of petrolatum-based antibiotic ointment placed in third molar extraction sites to prevent postoperative infection.

Methods: A case of bilateral myospherulosis is presented, in which large lesions complicated the procurement of a cortical block graft used to prepare a mandibular molar edentulous space for implant placement. By obtaining the block graft from a more lateral location on the mandible, an adequate graft was procured and was successfully grafted into an atrophic edentulous ridge.

A clinical evaluation of hydroxyapatite cement in the treatment of Class III furcation defects.

Background: Calcium hydroxyapatite cement (HAC) has been demonstrated in both animal models and human craniofacial defects to be safe, absorbable, osteoconductive, and possibly osteoinductive. This pilot study evaluated a novel technique using HAC to surgically obturate Class III mandibular molar furcation defects.

Methods: Following flap reflection, affected teeth in 6 patients were root planed and etched with citric acid.

The osteoinductive potential of demineralized freeze-dried bone allograft in human non-orthotopic sites: a pilot study.

Background: The use of demineralized freeze-dried bone allograft (DFDBA) in periodontal therapy is widely accepted. In addition to histologic studies demonstrating its role in regenerating the attachment apparatus, its recognized ability to exhibit osteoinduction in small laboratory mammals has prompted many clinicians to regard it as osteoinductive when utilized in periodontal therapy. Despite such a theoretical deduction, evaluating and establishing the osteoinductive potential of DFDBA in humans has been problematic.

Prevalence of dehiscences and fenestrations in modern American skulls.

Background: The purpose of this study was to examine the prevalence, distribution, and features of alveolar dehiscences and fenestrations in modern American skulls and correlate their presence with occlusal attrition, root prominence, and alveolar bone thickness.

Methods: A representative sample of 146 dentate modern American skulls from a collection at the National Museum of Natural History were examined.

Results: The skulls were from subjects ranging in age from 17 to 87 years old (mean 49.

Buccal alveolar exostoses: prevalence, characteristics, and evidence for buttressing bone formation.

Background: Buttressing bone formation has been described as the development of thickened or exostotic buccal alveolar bone in response to heavy occlusal forces. Little supporting evidence for this model has been found in previous literature, however, and there is little seen on the prevalence or characteristics of buccal alveolar exostoses.

Methods: A sample of 416 selected teeth and investing bone in 52 modern skeletal specimens at the National Museum of Natural History were examined.

Palatal tubercles, palatal tori, and mandibular tori: prevalence and anatomical features in a U.S. population.

The prevalence and features of 3 types of exostoses commonly encountered during periodontal surgery were studied in a sample of 328 modern American skulls drawn from the collection at the American Museum of Natural History. Measurements were made of the height, width, and breadth of exostoses. The relationship to teeth or other skeletal structures was also recorded.

A quantile plot for simultaneous representation of clinical and statistical attributes of probing change: application to early identification of the downhill patient.

When multiple periodontal sites are observed in patients over time there is an intention to identify those sites where there is important change, typically loss of attachment or increase in probing depth. A change may be declared if it: (a) exceeds a threshold level, and/or (b) is determined to be statistically significant (e.g.

Spontaneous bony exposure: a report of 4 cases of idiopathic exposure and sequestration of alveolar bone.

This paper describes 4 cases of spontaneous exposure and sequestration of alveolar bone. While one case was associated with an allergic mucositis, the other three were idiopathic involving large lingual exostoses.

Necotizing gingivostomatitis: NUG to noma.

Necrotizing gingivostomatitis (NG) is an increasingly rare but potentially serious infection that can present as a spectrum of clinical disease ranging from necrotizing ulcerative gingivitis to noma. The diagnostic triad for NG is pain, interdental ulceration, and gingival bleeding, but many cases also display fetid breath and pseudomembrane formation. Etiology is believed to be an opportunistic bacterial infection occurring in individuals debilitated by malnutrition, human immunodeficiency virus infection, or other systemic factors, including inadequate sleep, unusual stress, recent illness, alcohol use, and smoking.

Necrotizing ulcerative gingivitis, periodontitis, and stomatitis: clinical staging and predisposing factors.

Necrotizing ulcerative gingivitis (NUG), necrotizing ulcerative periodontitis (NUP), and necrotizing stomatitis (NS), collectively termed necrotizing gingivostomatitis (NG), represent a dramatic, but rare oral infection associated with diminished systemic resistance, including HIV infection. Over a 5-year period, 68 consecutive NG patients from a population with known HIV status were evaluated and treated. Lesions were staged (modified Pindborg), and clinical findings and predictor variables were compared to 68 random control subjects without NG.

Risk indicators for periodontitis in a military treatment population.

The association between the periodontal diagnosis and a variety of subject characteristics was studied in a group of 1,783 patients examined at a large military dental clinic. In order of importance, age greater than 30, smoking, male sex, and Filipino racial background were all found to be statistically significant risk indicators for the presence of moderate or advanced periodontitis. A logistic regression equation serving as a predictive model employing these four variables was presented.

The prevalence of periodontitis in a military treatment population.

A group of 1,984 males and females (age range 13 to 84) at a military dental clinic were given oral examinations with full-mouth circumferential periodontal probing. Diagnoses were made both for individual quadrants and for the entire mouth using clearly defined diagnostic criteria. The results showed 37% of the subjects had gingivitis only, 33% had early periodontitis, 14% had moderate periodontitis, 15% had advanced periodontitis, 0.

Peri-implant free gingival grafts: rationale and technique.

Inflamed and retractable mucosal margins around dental implants present unique problems in treatment. A rationale and technique for free gingival grafting around single or multiple implant abutments and two clinical examples are presented here.

Effect of an air-powder abrasive system on root surfaces in periodontal surgery.

The purpose of this study was to compare the effectiveness of an air-powder abrasive technique to conventional root planing during periodontal surgery. 7 patients scheduled for multiple extractions of periodontally-involved teeth were selected. Full thickness mucoperiosteal flaps were reflected, and proximal surfaces of 32 teeth were either ultrasonically scaled and exposed to the air-powder abrasive, or ultrasonically scaled and then manually root planed.

Gingival fibromatosis with hypertrichosis. A case report.

A case of gingival fibromatosis with hypertrichosis is reported in a 3-year-old girl. Partial recurrence was observed 6 months after surgical treatment. Psychological benefits resulting from the cosmetic improvement may outweigh the probability of recurrences in this rare condition.
