Evaluation Of Gingival Biotype And Recession Following Non-Surgical Periodontal Treatment Using 3-Dimensional Scan Methods.

The study evaluated the position of gingival margins in anterior teeth using clinical and 3-dimensional (3D) optical scanning method among patients subjected to non surgical periodontal treatment (NSPT). A single arm, longitudinal study was undertaken at the Archway Dental Center, University of Manchester, UK. History and clinical examination were done. Gingival recession, attachment loss (AL), and periodontal probing depth (PD) were recorded at baseline and 12-weeks follow-up. NSPT was done using hand and ultrasonic instruments. Impressions were made, the resultant gypsum models were scanned to generate 3D images. The change in the gingival level and thickness of facial gingiva were assessed. Out of eight patientsrecruited, three were lost to follow up. The 3D scan showed a poor correlation with the clinical assessment of gingival recession in anterior teeth following NSPT (r=- 0.0089). Recession did not improve after NSPT (p= 0.20).

Recubrimiento radicular de recesiones gingivales con matriz dérmica acelular / Root coverage of gingival recession with acellular dermal matrix

La recesión gingival es considerada como una deformidad o condición mucogingival, la Academia Americana de Periodontología, define a la recesión gingival como el desplazamiento del margen del tejido blando apical a la unión cemento-esmalte con la exposición de la superficie radicular. El tratamiento de las recesiones gingivales es un motivo de consulta común debido a razones estéticas, hipersensibilidad dentinaria, molestias durante el cepillado e incluso temor a la pérdida dentaria. Es una situación clínica común, 60% de la población humana tiene algún tipo de recesión gingival. Al realizar el examen clínico a paciente masculino de 55 años, se observó una recesión gingival tipo 1 (RT1) sin pérdida de inserción interproximal de la clasificación de Cairo. Se realizó el colgajo posicionado coronalmente (CPC) utilizando una matriz dérmica acelular (MDA) de origen humano OrACELL®. Se obtuvo resultado favorable en el recubrimiento de recesiones gingivales múltiples; considerándolos como una buena alternativa frente a los injertos gingivales autógenos. Concluyendo que, el uso de la matriz dérmica acelular para el tratamiento de la recesión gingival tipo 1 es una adecuada opción para el recubrimiento radicular. Se recomiendan más estudios a largo plazo para ver la estabilidad de los resultados obtenidos con la MDA (AU)

Gingival recession, considered a deformity or mucogingival condition, the American Academy of Periodontology, defines gingival recession as the exposure of the root surface resulting from migration of the gingival margin apical to the cementoenamel junction (CEJ). The treatment of gingival recessions is a common reason for consultation due to aesthetic reasons, dentin hypersensitivity, discomfort during brushing and even fear of tooth loss. It is a common clinical situation, 60% of the human population has some kind of gingival recession. Clinical examination of a 55-year-old male patient showed a type 1 gingival recession (RT1) without loss of interproximal insertion of the Cairo classification. Coronally advanced flap (CAF) was performed using an acellular dermal matrix (ADM) of human origin OrACELL®. Favorable results were obtained in the coating of multiple gingival recessions; considering them as a good alternative to autogenous gingival grafts. Concluding that, the use of the acellular dermal matrix for the treatment of gingival recession type 1, is a suitable option for root lining. Further long-term studies are recommended to see the elasticity of MDA outcomes (AU)

Clinical investigation of gingival papilla recession after orthodontic treatment in adults.

OBJECTIVE: To investigate the incidence, severity, susceptibility sites of gingival papillary recession (GPR) in adults after orthodontic treatment and the clinical impact of tooth extraction on GPR. METHODS: A total of 82 adult patients were recruited and then divided into extraction and non-extraction groups according to whether the orthodontic teeth were extracted (teeth that needed to be extracted when performing orthodontic treatment). The gingival conditions of the two groups of patients before and after treatment were recorded using intraoral photos, and the incidence, severity and predilection sites of GPR after correction were investigated. RESULTS: The results indicated that GPR occurred in 29 patients after correction, with an incidence rate of 35.4%. A total of 1648 gingival papillae were recorded among the 82 patients after correction, of which 67 exhibited atrophy, with an incidence of 4.1%. All occurrences of GPR were classified as papilla presence index 2 (PPI 2) (mild). The condition is most likely to occur in the anterior tooth area, especially in the lower incisor area. The results indicated that the incidence of GPR was substantially higher in the extraction group than in the non-extraction group, with the difference statistically significant. CONCLUSION: Following orthodontic treatment, adult patients will have a certain proportion of mild GPR, which is more common in the anterior tooth area, especially the lower anterior tooth area.

Minimally invasive non-surgical therapy (MINST) in stage III periodontitis patients: 6-month results of a split-mouth, randomised controlled clinical trial.

OBJECTIVES: To determine if minimally invasive non-surgical therapy (MINST) outperforms classical non-surgical periodontal therapy for stage III periodontitis with primarily suprabony (horizontal) type defects. MATERIALS AND METHODS: In a split-mouth randomised controlled trial, 20 patients' dental quadrants were randomly assigned to MINST or classical non-surgical treatment. The primary outcome variable was the number of sites with probing pocket depth ≥ 5 mm and BOP. Treatment method, tooth type, smoking status, and gender were evaluated using a multivariate multilevel logistic regression model. RESULTS: After 6 months, the percentage of sites with PD ≥ 5 mm and BOP that healed (MINST = 75.5%; control group = 74.1%; p = 0.98), and the median number of persisting sites (MINST: 6.5, control group: 7.0; p = 0.925) were similar in both groups. In the test and control groups, respectively, median probing pocket depths (2.0 mm vs. 2.1 mm) and clinical attachment level (1.7 mm vs. 2.0 mm) changed significantly (p < 0.05) but similarly. Significantly less gingival recession occurred in the MINST group's deep molar pockets compared to the control group (p = 0.037). Men (OR = 0.52, p = 0.014) and non-molars (OR = 3.84, p 0.001) had altered odds for healing of sites with PD ≥ 5 mm and BOP. CONCLUSIONS: MINST reduces gingival recession associated with molar teeth, although it performs similarly to traditional non-surgical therapy in treating stage III periodontitis with predominately horizontal-type defects. CLINICAL RELEVANCE: MINST performs similarly to non-surgical periodontal therapy in stage III periodontitis with predominantly suprabony defects. TRIAL REGISTRATION: Clinicaltrials.gov (NCT04036513) on June 29, 2019.

Interactions between Orthodontic Treatment and Gingival Tissue.

In recent years, as the number of adults seeking orthodontic treatment has increased, so too has the number of periodontal tissue problems, particularly regarding the impact on periodontal tissue of receiving orthodontic treatment. Orthodontic treatment improves the occlusion and appearance of teeth by moving the teeth appropriately. These movements have a significant impact on the interactions between the teeth and periodontal tissues. Orthodontic treatment can also recover tooth alignment for patients with tooth displacement caused by periodontitis; however, orthodontic treatment also often has adverse effects on periodontal soft tissue, such as gingivitis, gingival enlargement and gingival recession. The purpose of this review is to summarise the current evidence and solid knowledge of periodontal soft tissue problems in orthodontic treatment and outline some prevention strategies.

Colgajo de reposición coronal, con y sin injerto de tejido conectivo, para tratar recesiones gingivales / Coronally repositioned flap with and without connective tissue graft to treat gingival recession

Introducción: Las recesiones gingivales son afecciones de las encías, que son muy frecuentes y podrían provocar repercusiones estéticas, hipersensibilidad dentinaria y tener más tendencia a la formación de lesiones cervicales. Es necesario recubrir la superficie radicular mediante técnicas regenerativas periodontales. Objetivo: Comparar la cantidad de recubrimiento radicular, la profundidad al sondaje y el nivel de inserción clínica, empleando las técnicas de colgajo de reposición coronal, con y sin injerto de tejido conectivo, en pacientes con recesiones gingivales Miller I y II. Métodos: Se incluyeron un total de 16 pacientes con recesiones gingivales Miller clase I y II, de los cuales se seleccionaron 50 piezas dentarias tratadas quirúrgicamente para cubrir las recesiones. Se utilizaron las técnicas de colgajo de reposición coronal, con y sin injerto de tejido conectivo. Las mediciones clínicas fueron comparadas al inicio y a los tres meses posoperatorios. Resultados: Al tercer mes poscirugía los resultados del recubrimiento radicular, profundidad al sondaje y el nivel de inserción clínica para la técnica colgajo de reposición coronal con injerto de tejido conectivo, fueron 0,96 ± 1,33; 0,87 ± 0,63; 1,83 ± 1,7 y para la técnica colgajo de reposición coronal fueron 1,44 ± 1,19; 1,04 ± 0,52; 2,48 ± 1,48, respectivamente. Al comparar el recubrimiento radicular intergrupo no se encontraron diferencias significativas (p = 0,11). Sin embargo, al comparar la profundidad al sondaje intergrupo (p = 0,04), el nivel de inserción clínica intergrupo (p = 0,001) y todas las mediciones clínicas intragrupo (p = 0,001), se encontraron diferencias significativas. Conclusiones: La técnica de colgajo de reposición coronal, con y sin injerto de tejido conectivo, demostró diferencias significativas en la profundidad al sondaje y el nivel de inserción clínica en recesiones gingivales Miller I y II. No se alcanzaron diferencias significativas para el recubrimiento radicular en ambas técnicas a los 3 meses de seguimiento(AU)

Introduction: Gingival recession is a very common gum condition which may result in aesthetic alterations and dentin hypersensitivity, and increase the probability of cervical lesions. It is necessary to cover the root surface using periodontal regeneration techniques. Objective: Compare the amount of root coverage, probing depth and clinical insertion level, using coronally repositioned flap techniques with and without connective tissue graft in patients with Miller I and II gingival recessions. Methods: A total 16 patients with Miller class I and II gingival recessions were included in the study, from whom 50 teeth were selected which had been treated surgically to cover the recessions. The techniques used were coronally repositioned flap with and without connective tissue graft. Clinical measurements were compared at the start of the postoperative period and three months later. Results: Three months after surgery, root coverage, probing depth and clinical insertion level were 0.96 ± 1.33; 0.87 ± 0.63; 1.83 ± 1.7, respectively, for coronally repositioned flap with connective tissue graft, and 1.44 ± 1.19; 1.04 ± 0.52; 2.48 ± 1.48, respectively, for coronally repositioned flap. Root coverage intergroup comparison did not find any significant differences (p = 0.11). However, intergroup comparison of probing depth (p = 0.04) and clinical insertion level (p = 0.001), and all the intragroup clinical measurements (p = 0.001) did find significant differences. Conclusions: Coronally repositioned flap technique with and without connective tissue graft showed significant differences in terms of probing depth and clinical insertion level in Miller I and II gingival recessions. At three months' follow-up, no root coverage significant differences were observed for either technique(AU)

Evaluation of gingival recessions with conventional versus digital methods.

OBJECTIVES: The present study aimed to compare the conventional clinical and a digital method for evaluating differences in gingival recession (ΔREC) in patients with advanced periodontitis treated with the non-surgical treatment protocol. METHODS: Agreement between the methods was evaluated on a sample of ten patients with periodontitis (stage III/IV, grade B/C) with acquired clinical measurements and digital models from baseline (T0) and 12-months after non-surgical treatment of periodontitis (T1). The evaluation was performed on maxillary teeth from right to left second premolar resulting in overall 99 teeth. Clinical evaluation was performed by subtracting the distance measurements between gingival margin and cemento-enamel junction, obtained at T0 and T1 by a calibrated examiner (intra-examiner agreement >90%). The digital evaluation was performed directly by measuring the distance between the gingival margins on superimposed T0 and T1 digital models. Using Bland-Altman and statistical analysis, all six measurements sites around each included tooth (n=594) acquired with both methods were compared. RESULTS: Median ΔREC (5th and 95th percentile) acquired with a conventional clinical and digital method was 0.0mm (-2.0 - 1.0) and -0.4mm (-1.6 - 0.8), respectively (p<0.0001). The complete agreement between rounded digital and clinical ΔREC values was only 38%, revealing high disagreement also confirmed by Bland-Altman analysis with 95% limits of agreement ranging from -2.6 to 1.8mm. Absolute differences between the methods higher than 0.5 and 1 mm, was found in 61% and 38% of measurement sites, respectively. CONCLUSIONS: The conventional clinical method for ΔREC evaluation exhibits lower sensitivity and accuracy than the digital method. CLINICAL SIGNIFICANCE: The quality of both clinical and research data in periodontology and implantology can be considerably improved by the digital method while still preserving the compatibility with the conventional clinical method.

[Clinical effectiveness evaluation of gingival recession by using perioscope as an adjunct to non-surgical periodontal therapy].

PURPOSE: To investigate the effects of ultrasonic scaling and root planning(SRP) assisted by perioscope on gingival recession of maxillary lateral incisor. METHODS: Thirty-six outpatients with moderate to advanced chronic periodontitis from the Department of Periodontology at Dental and Ophthalmic Clinic of Putuo District from June 2020 to December 2020 were collected as research objects. Periodontal treatment was carried out according to a single-blind split-mouth self-control design randomly with(experimental group, namely perioscope group) or without(control group, namely SRP group) periodontal endoscope．The labial periodontal probing depth (PD), labial attachment loss (AL) and gingival recession(GR) in the maxillary lateral incisors were recorded at baseline, 3 and 6 months, and compared among groups by SPSS 22.0 software package. RESULTS: There was no significant difference between perioscope group and SRP group at baseline. ΔGR (the recession extent of gum within two observation time) in perioscope group was significantly smaller than that in SRP group at 3 months（P<0.05）. There was no significant difference in other periodontal indicators at 3 and 6 months between the 2 groups after treatment, but it can be found that the degree of PD reduction and AL improvement in perioscope group was more than those in SRP group, this trend was most obvious at 3 months. PD and AL were significantly different between baseline and 3 months or 6 months in the two groups. There were significant differences in ΔGR at 3 months and 6 months between the two groups. CONCLUSIONS: Compared with routine SRP, the extent of root surface debridement with perioscope-assisted SRP is thorough and less invasive, and the reduction of gingival recession of labial surface of maxillary lateral incisor at 3 months is significantly less; thus, the aesthetic effect is prominent.

Rethinking the decision-making process to treat gingival recession associated with non-carious cervical lesions.

The presence of a tooth-surface defect, such as a non-carious cervical lesion (NCCL), associated with sites of gingival recession (GR) defects creates a combined soft tissue/tooth defect (CD) that requires a different treatment plan. This study aimed to critically review the literature regarding the available treatment protocols for CDs and suggest a new decision-making process. NCCLs were classified as Class A-: the cementoenamel junction (CEJ) was visible and the root surface discrepancy was < 0.5 mm (no step); Class A+: CEJ was visible and the root surface discrepancy was > 0.5 mm (with a step); Class B-: unidentifiable CEJ without a step; Class B+: unidentifiable CEJ with a step. NCCLs affecting both root and crown surfaces (Class B) lead to CEJ destruction and consequently eliminate an important landmark used before and after root coverage procedures. The depth of the root surface discrepancy is vital owing to its possible impact on soft tissue adaptation after healing, which, in turn, may influence the treatment options, namely the use of graft and/or composites to compensate for the discrepancy. Clinically, a step with horizontal depth greater than 0.5 mm should be recognized as the minimum threshold value to define this condition. Extremely deep defects tend to assume a V-shaped topography. Therefore, extremely deep V-shaped defects were classified into subclasses A+V, a V-shaped defect, and B+V, a V-shaped defect with loss of CEJ, for management considerations. The treatment options, supported by the literature, and a decision-making process to deal with each condition are presented.

[Home treatment of dental hyperesthesia symptoms]. / Simptomaticheskoe lechenie giperestezii zubov v domashnikh usloviyakh.

THE AIM OF THE STUDY: Was to assess the efficacy of Sensodyne toothpast for the improvement of dental hypersensitivity of various origin and the duration of the achieved effect. MATERIALS AND METHODS: We examined 142 patients of which 95 people had tooth sensitivity. Of these, 4 groups were formed homogeneous by age and sex. Group 1 comprised 27 people (average age 34±3 years) with I grade dental abrasion. Group 2 comprised 23 people (average age 33±5 years) with II grade dental abrasion. Group 3 consisted of 23 people (average age 37±4 years) with grade 3 abrasion with gingival recession of varying severity. Group 4 (comparison) comprised 22 people (mean age 36±4 years) with tooth hypersensitivity who were offered a different toothpaste. The severity of hyperesthesia was assessed using the Schiff method. RESULTS: The study revealed statistically significant decrease in dental sensitivity in all studied groups. The first positive results were noted by day 3. The maximum effect was achieved by day 30 regardless of the etiology of the primary pathology. The hypersensitivity decreased in group 1 from 1.69±0.59 to 0.48±0.20 (by 71.5%), in group 2 from 1.78±0.88 to 0.3±0.22 (by 83.1%), in group 3 from 1.94±0.6 to 0.35±0.17 (by 82%). The duration of the effect obtained was 60 days. In the comparison group, the symptom of hyperesthesia decreased by 51% after 30 days with gingival recession and increased abrasion of hard tissues when using another toothpaste. The achieved effect of reducing hyperesthesia was less stable. At day 60 it decreased by 30% from the maximum value. CONCLUSION: The study proved the high efficiency of the Sensodyne toothpaste as a home remedy for symptomatic treatment of hyperesthesia.

Herbst-multibracket appliance treatment: is there an association between lower incisor position changes and the development of labial gingival recessions?

PURPOSE: To assess a potential association between lower incisor (LI) position changes during Herbst-multibracket appliance (Herbst-MBA) treatment and the development of labial gingival recessions (LGR). METHODS: All class II patients (Department of Orthodontics, University of Giessen, Giessen, Germany) who had undergone Herbst-MBA treatment until 2015 with study models and lateral cephalograms available from before (T0) and after treatment plus ≥24 months of retention (T3) were included (n = 259). Lateral cephalograms were evaluated regarding LI position changes: iiL/ML (angle between LI long axis and mandibular plane [MP]), ii-MLPg (distance between LI incisal edge and a line perpendicular to MP through pogonion), apex-MLPg (distance between LI apex and a line perpendicular to MP through pogonion), ii-MLii (distance between LI incisal edge and MP on a line perpendicular to MP through incisal edge). Using study models the distance between the cementoenamel junction and the deepest point of the gingival margin was defined as LGR. RESULTS: The following cephalometric mean changes were recorded (T0-T3): iiL/ML +5.9 ± 5.76° (p = 0.929), ii-MLPg -0.2 ± 0.25 mm (p = 0.430), apex-MLPg +0.1 ± 0.32 mm (p = 0.363), ii-MLii +0.1 ± 0.36 mm (p = 0.206). The mean increase of LGR magnitude measured on the study models was 0.1 ± 0.35 mm. However, no association with the cephalometric LI position changes was found (|R| ≤ 0.2). CONCLUSION: There is no association between the amount of LI position changes and the development of LGR during Herbst-MBA treatment plus retention. Nevertheless, individual predisposition or excessive treatment changes and extraordinary treatment approaches, respectively, might still lead to development of LGR.

A Review of the Role of Probiotic Supplementation in Dental Caries.

Dental diseases are among the common health issues experienced around the world. Dental caries is one of the most predominant oral diseases worldwide. Major factors associated with caries development include poor oral hygiene, the content of specific carbohydrates in the diet, dental biofilm formation, the cariogenic microbial load, reduction in salivary flow, insufficient fluoride exposure, gingival recession, genetic factors, and lack of personal attention to one's dental health. Several preventive measures have been implemented to reduce the risk of the development of caries. Probiotics are live microbes that when administered in suitable amounts confer health benefits on the host; they are recognized as potential adjunct therapeutic agents for several diseases. The present manuscript summarizes recent findings on the role of probiotics in dental caries prevention and the possible mechanisms of probiotic effects. Review of the literature indicates the regular consumption of probiotic products significantly reduced the risk of caries by inhibiting cariogenic bacteria and enriching commensal microbes in the oral cavity. Buffering the salivary pH, production of bacteriocin and enzymes (dextranase, mutanase, and urease), the capacity of competing for the adhesion and colonization on tooth surfaces are the possible mechanisms behind the beneficial effect of probiotics. Further studies are necessary to address the efficacy of long-term probiotic supplementation on the control of dental diseases and the influence of childhood probiotic supplementation on the risk of caries development.

CO2 Laser De-epithelization Technique for Subepithelial Connective Tissue Graft: A Study of 21 Recessions.

BACKGROUND/AIM: To report cases in which we achieved sufficient width of the keratinized gingiva using a coronally advanced flap in combination with a subepithelial connective tissue graft (SCTG) obtained by the 'CO2 laser de-epithelization technique' (CODE). PATIENTS AND METHODS: Eleven patients with 21 Miller Class I, II, and III gingival recessions had surgery. To prepare SCTG, free gingival grafts were harvested and de-epithelialized extra-orally. De-epithelialization was conducted by irradiation of CO2 laser. Postoperative examinations were performed at 12 months. RESULTS: At 12 months, statistically highly significant root coverage was achieved in all recessions. Complete root coverage was obtained in 7 of the 21 recessions. The treatment yielded mean root coverage of 41.0%, and was associated with a mean gain of keratinized gingiva of 2.9±0.3 mm. CONCLUSION: The use of CODE allows harvesting grafts of excellent quality and quantity and increases the keratinization of the overlying mucosal epithelium.

BIOACTIVE GLASS-CERAMIC COMPOSITION IN SURGICAL MANAGEMENT OF PERIODONTAL INTRABONY DEFECTS.

It has been earlier proposed a novel graft on basis of bioactive glass-ceramics for infected bony defects, where silver and copper ions are represented as antibacterial agents. The objective was to investigate clinical and radiological efficacy of the bioactive glass-ceramic composition (BGCC) as bone substitute material for periodontal intrabony defects surgery. In a group of 47 patients with periodontitis was conducted controlled clinical study of the proposed composition. As a control in 24 patients it has been used deproteinized bovine bone mineral (DBBM) with collagen membrane. Such parameters as pocket probing depth (PPD), clinical attachment level (CAL), gingival recession, the early wound-healing index (EHI), hygienic and gingival indices, radiological bone density were used for evaluation surgical outcomes. Guided tissue regeneration was carried out in 56 intrabony defects. A year after surgery it has been determined almost the same significant (p<0.05) decrease PPD to 53.5% in the BGCC group and to 45.7% in the DBBM group, CAL gain to 30.4% in the BGCC group and to 28.0% in the DBBM group. Intrabony defects were bone filled to 27.5% and to 30.1% respectively with no significant differences for comparison groups. However, it was noted the advantage of significant increasing bone density in treated sites with BGCC (p<0.05). It also has shown a tendency to decrease discomfort for patients and to improve wound healing in postsurgical period according to the EHI in the same group. The using of BGCC with collagen membrane leads to significant reduction in probing depth, clinical attachment level gain, raises bone density profile. However, further long-term clinical studies with histological evaluation are necessary.

Xenogeneic collagen matrix versus connective tissue graft for the treatment of multiple gingival recessions: A systematic review and meta-analysis.

A systematic review and meta-analysis was performed to understand the efficacy of xenogeneic collagen matrix (CMX) compared with connective tissue graft (CTG) for the treatment of multiple adjacent gingival recessions (MAGRs). A literature search was performed for published randomized controlled trials in adult patients (≥18 years old) with Multiple Adjacent Miller class I and II gingival recessions (MAGRs). The assessments included recession depth, Recession width, complete root coverage, mean root coverage, probing depth, clinical attachment level, and keratinized tissue width. Pooled data were analyzed using fixed- and random-effects models, and Forest plots were constructed. Heterogeneity within studies was calculated to assess publication bias. Four randomized controlled trials were included based on the eligibility criteria. Although the recession depth, complete root coverage, and mean root coverage were significantly lower with CMX (p = .017 and p = .001, p = .001, respectively), there was no statistically significant difference in the Recession width between CMX and CTG (p = .203). CMX showed significantly lower Probing Depth than CTG (p = .023); however, no significant difference in clinical attachment level (p = .060) and keratinized tissue width (p = .052) was observed between the groups. Owing to the heterogeneity in the included studies, firm conclusions cannot be drawn regarding the noninferiority of CMX compared with CTG. Long-term studies are therefore needed to conclusively establish the relative efficacy of CMX in MAGR.

Treatment of peri-implant soft tissue defects: a narrative review.

Soft tissue defects around dental implants, such as papilla or volume loss, peri-implant recession and alterations of the ridge color and/or texture, lead to esthetic and functional complaints. Treatments of these defects in implants are more demanding than in teeth because peri-implant tissue exhibits different anatomical and histological characteristics. This narrative review discusses the proposed treatments for soft tissue defects around implants in the current literature. Several clinical and pre-clinical studies addressed methods to augment the quantity of the peri-implant keratinized mucosa. Autogenous grafts performed better than soft tissue substitutes in the treatment of soft tissue defects, but there is no clinical consensus on the more appropriate donor area for connective tissue grafts. Treatment for facial volume loss, alterations on the mucosa color or texture and shallow peri-implant recessions are more predictable than deep recessions and sites that present loss of papilla. Correction of peri-implant soft tissue defects may be challenging, especially in areas that exhibit larger defects and interproximal loss. Therefore, the regeneration of soft and hard tissues during implant treatment is important to prevent the occurrence of these alterations.

Long-Term Outcome (10 Years) of Multiple Recession-Type Defects Treated With Acellular Dermal Matrix Graft and Coronally Advanced Flap: A Case Report.

INTRODUCTION: There is limited evidence related to the long-term treatment outcomes of acellular dermal matrix graft (ADMG) plus coronally advanced flap (CAF) for the treatment of multiple recession defects. The aim of this case report is to assess the short- and long-term clinical outcomes of Miller Class I multiple gingival recession-type defects in the maxilla treated with ADMG plus CAF. CASE PRESENTATION: A 36-year-old female patient smoking < five cigarettes per day presented multiple adjacent Miller Class I gingival recession in the left maxilla and was referred for treatment with chief complaints of dental hypersensitivity and esthetics. Root coverage was achieved by ADMG + CAF and the patient underwent a 10-year follow-up. CONCLUSIONS: Within the limits of this case report, mean root coverage obtained at 6 months could not be maintained in the long term. A significant relapse was detected after 10 years, from 80% complete root coverage (CRC) at 6 months to 40% at 10 years. Monitoring, compliance, and reinstructions in oral hygiene techniques seem mandatory for minimizing relapse of gingival recessions after root coverage procedures.

Interdisciplinary management of gingival recession and pathologic teeth migration-Revisiting dental aesthetics.

Poor aesthetics due to gingival recession can be a common concern among patients, specifically in individuals with gummy or high smile line. Various factors including patient related, site specific and technical factors need to be considered while treating gingival recession, as they all have a significant bearing on treatment success. Patients having aesthetic problems due to exposed root surfaces should have surgical root coverage procedures. Pathologic migration of anterior teeth is another aesthetic and functional problem that may be associated with advanced or chronic periodontal disease. Literature suggests the destruction of periodontal supporting structures to be the most commonly associated factor responsible for pathologic tooth migration. This case report is about the management of dental aesthetics of a middle-aged lady who was concerned about recession and pathologic tooth migration secondary to chronic periodontal disease. Employing multidisciplinary approach that included surgery, periodontics, endodontic and prosthodontics, the lady was provided with an aesthetically pleasing dentition.
