[Show abstract][Hide abstract] ABSTRACT: Gingival recession remains an important problem in dental esthetics. A new dermal matrix material has been introduced, but its effectiveness has not been studied and compared to current dermal matrix material. The aim of this study is to compare the healing associated with a coronally advanced flap for root coverage in areas of localized tissue recession when using Alloderm (ADM) and Puros Dermis (PDM).
A split-mouth design was used for this study, with 52 contralateral sites in 14 patients with Miller Class I or III facial tissue recession. Twenty-six sites were treated with coronally advanced flap using PDM, and 26 sites were treated with coronally advanced flap using ADM, all followed for 6 months. Clinical measurements of vertical recession, keratinized tissue, probing depths, and attachment levels were made initially, at 3 months, and at 6 months.
Both groups had significant improvement in the amount of recession coverage with means of 2.83 mm for the PDM and 3.13 mm for the ADM. The percentage of root coverage was 81.4% for the PDM and 83.4% for the ADM; differences between the materials were not statistically significant.
Based on the results of this study, there was no statistical or clinical difference in the amount of root coverage, probing depth, or keratinized tissue in coronally advanced flaps for root coverage with either of the two acellular dermal matrix materials. Both materials were successful in achieving root coverage.

[Show abstract][Hide abstract] ABSTRACT: The aim of this study was to compare root coverage using acellular dermal matrix (ADM) with and without enamel matrix derivative (EMD) on the percentage of root coverage, probing attachment level, and the amount of keratinized tissue in the treatment of localized recession.
Eighty-two contralateral sites in 14 patients with >or=2 mm of Miller Class I or III buccal tissue recession were treated. Forty-one test sites were treated with coronally advanced flap (CAF) using ADM in conjunction with EMD, whereas 41 control sites were treated with CAF using ADM alone. A split-mouth design was used for this study with 82 sites. Patients were followed for 3 and 6 months. A paired t test was conducted with the subject as the unit of analysis.
Based on paired t tests, both groups had significant improvement in the percentage of root coverage, probing attachment levels, and increased keratinized tissue. Only keratinized tissue in the test group demonstrated a statistically significant greater increase compared to controls at the 6-month evaluation (P = 0.006).
The use of EMD in conjunction with ADM resulted in a statistically significant effect on keratinized tissue increase, but no significant effects on probing attachment level or percentage of root surface coverage.

[Show abstract][Hide abstract] ABSTRACT: Mucous membrane pemphigoid (MMP) describes an autoimmune disease with a range of variants, including those with oral, ocular, and cutaneous lesions. Persistent oral lesions, lack of effective oral hygiene, and plaque accumulation may increase the risk of long-term periodontal disease. However, to our knowledge, no studies have evaluated the relationship between the presence of gingival MMP and periodontal health. The purpose of this study was to evaluate the possible impact of gingival pemphigoid lesions on the human periodontium.
Twenty patients with histologic confirmation of subepithelial separation with or without direct immunofluorescence testing were randomly chosen to participate in a study evaluating their periodontal status. Parameters evaluated included plaque score, gingival index, bleeding index, probing depths, recession, clinical attachment level, mobility, furcation involvement, number of missing teeth, and Machtei criteria, a previously defined criteria for periodontitis. Individuals matched with respect to age, gender, and smoking history were selected and evaluated for the same parameters.
MMP patients had statistically significant larger mean gingival index scores than age, gender, and smoking history matched controls. Plaque scores, bleeding index, mobility, furcations, clinical attachment level, recession, and periodontal status did not show statistically significant differences between MMP and control patients. A statistically significant difference in plaque index was found when patients with MMP in treatment were compared to patients with MMP in remission. Among patients with MMP, those diagnosed >5 years in the past had statistically significantly greater Class I furcation involvement and recession on facial and lingual surfaces of teeth.
A relationship was found to suggest that patients with MMP exhibit more gingival inflammation than a control population. Among patients with MMP, patients currently in treatment have higher plaque indices than those in remission and not receiving treatment. Furthermore, when comparing patients with MMP who received a diagnosis>5 years in the past to those with a diagnosis in the past 5 years, statistically significantly greater Class I furcation and facial and lingual recession were measured. Long-term follow-up in this population may provide additional information as to periodontal progression in MMP versus control patients.

[Show abstract][Hide abstract] ABSTRACT: The primary aim of this randomized, controlled, clinical investigation was to evaluate the differences in clinical parameters of root coverage procedures utilizing coronally advanced flaps (CAF) with and without enamel matrix derivative (EMD). Another aim was to evaluate if EMD can influence keratinization of tissues utilizing these procedures.
Fifty-eight contralateral sites in 17 patients with > or = 2 mm of Miller Class I, II, and III buccal marginal tissue recession were treated. Test sites received CAF plus EMD while control sites were treated with CAF only, with each patient serving as his own control. Patients were followed for 3 and 6 months. All data were analyzed using the method of generalized estimating equations. A P value <0.05 was considered significant (alpha = 0.05).
There was a mean increase in keratinized tissue of 0.60 mm for test sites and a mean decrease of 0.05 mm for control sites. Test sites demonstrated significantly better root coverage (P<0.001), 89.7% and 92.9% root coverage after 3 months and 6 months, respectively, while control sites had 56.6% and 66.8% root coverage after 3 months and 6 months, respectively. There was significantly more root coverage among test sites compared to control sites, regardless of arch or Miller classification.
Based on the results of this study, the application of enamel matrix derivative to denuded root surfaces receiving coronally advanced flaps significantly increased the percentage of root coverage compared to CAF without EMD. In addition, EMD application was accompanied by a significant increase in keratinized tissue 6 months after surgery.
