RESUMO
OBJECTIVE: The aim of this preclinical study was to compare the ability of tapered and cylindrical bristles to penetrate the peri-implant sulcus. METHODS: A full mandibular dental arch was reproduced in plaster cast. In site #3.6 a hollow glass cylinder was positioned simulating a 4 mm diameter implant and the gingival component was recreated by using dedicated silicone. A Bass brushing technique was performed from the vestibular side in humid environment. During it, the penetration of the bristles between the gum and the implant was recorded by mean of an optic fibre fixed inside the cylinder. The protocol included 5 toothbrushes per group and 10 tests per toothbrush, for a total of 50 assessments for each of the two groups. A scale of 5 grades for bristle penetration was defined: grade 0 (× < 2 mm), grade 1 (2 ≤ × < 3 mm), grade 2 (3 ≤ × < 4 mm), grade 3 (4 ≤ × < 5 mm) and grade 4 (5 ≤ × < 8 mm). From the video recordings the highest value of penetration was identified for each test. RESULTS: The tapered bristles showed an 8 times greater penetration capacity (p = 0.001) in respect to the cylindrical bristles (multilevel analysis). The percentage of tests reaching depths ≥3 mm was 86% for tapered group and 28% for the cylindrical group. CONCLUSION: This preclinical study shows a clear and superior penetration capacity of the tapered bristles in respect to traditional cylindrical ones. For tapered bristles, a potentially greater hygienic efficacy around dental implants is suggested.

Inadequate quality, quantity, or aesthetics of the peri-implant soft tissues can result from a combination of factors related to the outcome of treatments performed before, during, or after implant placement. In this paper, we describe in detail the treatment errors that can pave the way for the onset of mucositis or give rise to soft tissue complications such as peri-implant soft tissue discoloration or dehiscence, graft exposure, or scar formation. By tracing the error back to the planning or surgical stage, clinical insights on surgical soft tissue management are provided to avoid or treat complications that affect the status of the peri-implant soft tissues. Mastering the learning curve and knowing the limitations of each technique are fundamental for preventing added treatment failures that can result in increased patient morbidity and overall discontent.

Immediate implant placement is considered the treatment of choice for single tooth replacement in the esthetic area. However, this treatment is associated with several critical drawbacks related to the inadequate assessment/management of the soft and hard peri-implant tissues and their subsequent remodeling, resulting in peri-implant soft-tissue defects that can lead to impaired esthetic outcomes in time. We describe in detail how the mucogingival approach to immediate implant placement ensures a standard result regardless of the baseline soft-hard tissue situation. Fully guided implant placement guarantees an adequate three-dimensional implant placement, the flap design makes it possible to perform bone augmentation with complete visibility of the area being treated, allows soft tissue augmentation with proper fixation of the connective tissue graft, and the placement of an immediate provisional ensures stabilization of the peri-implant tissues throughout the healing period.

Alveolar ridge preservation is routinely indicated in clinical practice with the purpose of attenuating postextraction ridge atrophy. Over the past two decades numerous clinical studies and reviews on this topic have populated the literature. In recent years the focus has primarily been on analyzing efficacy outcomes pertaining to postextraction dimensional changes, whereas other relevant facets of alveolar ridge preservation therapy have remained unexplored. With this premise, we carried out a comprehensive evidence-based assessment of the complications associated with different modalities of alveolar ridge preservation and modeled the cost-effectiveness of different therapeutic modalities as a function of changes in ridge width and height. We conclude that, among allogeneic and xenogeneic bone graft materials, increased expenditure does not translate into increased effectiveness of alveolar ridge preservation therapy. On the other hand, a significant association between expenditure on a barrier membrane and reduced horizontal and vertical ridge resorption was observed, though only to a certain degree, beyond which the return on investment was significantly diminished.

Palatal-tissue harvesting is a routinely performed procedure in periodontal and peri-implant plastic surgery. Over the years, several surgical approaches have been attempted with the aim of obtaining autogenous soft-tissue grafts while minimizing patient morbidity, which is considered the most common drawback of palatal harvesting. At the same time, treatment errors during the procedure may increase not only postoperative discomfort or pain but also the risk of developing other complications, such as injury to the greater palatine artery, prolonged bleeding, wound/flap sloughing, necrosis, infection, and inadequate graft size or quality. This chapter described treatment errors and complications of palatal harvesting techniques, together with approaches for reducing patient morbidity and accelerating donor site wound healing. The role of biologic agents, photobiomodulation therapy, local and systemic factors, and genes implicated in palatal wound healing are also discussed.

Root coverage procedures have become very common in clinical dental practice. Even though these techniques are considered safe, the clinician may face several issues during the therapy due to their surgical nature. Some of these issues can be defined strictly as complications inherent to the procedure, whereas others are medical errors or treatment errors. This review will focus on describing treatment errors and complications that may arise during different phases of the root coverage therapeutic process and on how to prevent and manage them.

OBJECTIVES: To review the available literature on the medium- and long-term effects of soft tissue augmentation (STA) at implant sites and to explore the effects of the different approaches on clinical-, patient-reported, and health-related parameters. MATERIALS AND METHODS: A comprehensive electronic and manual search was performed to identify prospective clinical studies that assessed the medium- and long-term (≥36 months) outcomes following STA, including number of sites maintaining peri-implant health and number of sites developing peri-implant disease, incidence of complications, stability of the clinical, volumetric, and radiographic parameters, and patient-reported outcome measures (PROMs). RESULTS: Fifteen studies were included in the qualitative analysis. STA was performed with either a bilaminar- or an apically positioned flap (APF) approach, in combination with autogenous grafts (free gingival graft [FGG] and connective tissue graft [CTG]) or substitutes (acellular dermal matrix [ADM] and xenogeneic cross-linked collagen matrix [CCM]). An overall high survival rate was observed. Most of the augmented implant sites maintained peri-implant health in the medium and long term, with the incidence of peri-implant mucositis and peri-implantitis ranging from 0% to 50% and from 0% to 7.14%, respectively. The position of the soft tissue margin following APF + FGG and bilaminar approaches involving CTG or CCM was found to be stable over time. No substantial changes were reported for plaque score/index, bleeding on probing/bleeding index, and probing depth between early time points and following visits. CTG-based STA procedures resulted in a stable or increased dimension of keratinized mucosa width (KMW) and mucosal thickness (MT)/volumetric outcomes over time, when compared with early follow-ups. Most of the included studies described stable marginal bone levels at the grafted implant sites over time. No substantial changes for patient-reported outcomes and professionally assessed esthetic results were reported at different time points. CONCLUSIONS: Implants that received STA showed overall high survival rate and relatively low incidence of peri-implantitis in the medium and long term. Augmented sites seem to maintain the level of soft tissue margin and marginal bone over time, while non-augmented implants may exhibit apical shift of the soft tissue margin. The overall favorable early outcomes obtained with STA are maintained in the medium and long term, with an increase in KMW and MT that may be expected over time at CTG-augmented sites.

OBJECTIVES: The aims of Working Group 1 were to address the role (i) of the buccolingual bone dimensions after implant placement in healed alveolar ridge sites on the occurrence of biologic and aesthetic complications, and (ii) of soft tissue augmentation (STA) on the stability of clinical, radiographic, and patient-related outcomes of implant treatments. MATERIALS AND METHODS: Two systematic reviews were prepared in advance of the Consensus Conference and were discussed among the participants of Group 1. Consensus statements, clinical recommendations, recommendations for future research, and reflections on patient perspectives were based on structured group discussions until consensus was reached among the entire group of experts. The statements were then presented and accepted following further discussion and modifications as required by the plenary. RESULTS: Dimensional changes of the alveolar ridge occurred after implant placement in healed sites, and a reduction in buccal bone wall thickness (BBW) of 0.3 to 1.8 mm was observed. In healed sites with a BBW of <1.5 mm after implant placement, increased vertical bone loss, and less favorable clinical and radiographic outcomes were demonstrated. Implants with buccal dehiscence defects undergoing simultaneous guided bone regeneration, showed less vertical bone loss, and more favorable clinical and radiographic outcomes, compared to non-augmented dehiscence defects during initial healing. At healthy single implant sites, probing depths, bleeding and plaque scores, and interproximal bone levels evaluated at 1 year, remained stable for up to 5 years, with or without STA. When single implant sites were augmented with connective tissue grafts, either for soft tissue phenotype modification or buccal soft tissue dehiscence, stable levels of the soft tissue margin, and stable or even increased soft tissue thickness and/or width of keratinized mucosa could be observed from 1 to 5 years. In contrast, non-augmented sites were more prone to show apical migration of the soft tissue margin in the long-term. Favorable aesthetic and patient-reported outcomes after STA were documented to be stable from 1 to 5 years. CONCLUSIONS: It is concluded that dimensional changes of the alveolar ridge occur after implant placement in healed sites and that sites with a thin BBW after implant placement are prone to exhibit less favorable clinical and radiographic outcomes. In addition, it is concluded that STA can provide stable clinical, radiographic, aesthetic, and patient-reported outcomes in the medium and long-term.

INTRODUCTION: We recently developed a non-invasive sampling procedure for oral squamous cell carcinoma (OSCC) detection based on DNA methylation analysis of a panel of 13 genes. Oral cancer, as well as acute and chronic inflammatory diseases, may influence the methylation level of several genes in the oral cavity. In the present study, we evaluated the presence of periodontal disease (PD) and the methylation status using our 13-gene panel. METHODS: Oral brushing specimens were collected from three different patient groups: 23 gingival OSCC patients, 15 patients affected by PD, and 15 healthy volunteers lacking evidence of PD. DNA methylation analysis was performed and each sample was determined to be positive or negative based on a predefined cut-off value. RESULTS: Positive results were found for 23/23 OSCC patients, 3/15 PD patients, and 0/15 samples from healthy volunteers. The GP1BB and MIR193 genes in the PD group exhibited mean methylation levels similar to OSCC patients. ZAP70 showed different methylation levels among three groups. CONCLUSION: Preliminary data identified shared epigenetic alterations between PD and OSCC patients in two inflammatory genes (GP1BB and MIR193). This study may help to identify potential links between the two diseases and serve as a starting point for the future research focused on pathogenesis.

OBJECTIVES: The treatment of gingival recessions (GRs) is operator-sensitive and dependent upon several local anatomical factors. The aim of this study was to introduce a difficulty score for the treatment of localized GRs with the coronally advanced flap (CAF) and to test its consistency among different operators. MATERIALS AND METHODS: A rubric (difficulty score) consisting of the assessment and grading of 8 anatomical parameters (anatomical papilla, apical and lateral keratinized tissue width, apical and lateral frenum, vestibulum depth, scar tissue, and mucosal invagination) is described based on the available evidence and the authors' experience. Inter-examiner agreement, with the score, was tested on 32 localized GRs among four different experienced practitioners. RESULTS: Minor discrepancies were observed in the total scores between the reviewers (intraclass correlation coefficient [ICC] 0.95). A good reproducibility, with ICCs ranging from 0.56 to 0.98, was found for the individual parameters. All models showed high absolute variance contribution conveying true differences among the cases, and small examiner variance, demonstrating minor systematic variability among the four reviewers and reproducible evaluations. CONCLUSIONS: The proposed difficulty score for the treatment of GRs with CAF was reproducible among different operators. Clinical interventional studies are the next step to validate the clinical magnitude of the present score. CLINICAL RELEVANCE: A novel tool for evaluating the difficulty of the treatment of isolated gingival recession using CAF was described. Clinicians can benefit from this score when assessing the expected level of complexity of the surgical case.

OBJECTIVES: The present study aimed to explore the impact of different periodontal surgical treatments on the quality of life and postoperative morbidity. MATERIALS AND METHODS: The present study is a single-center, prospective, observational cohort trial. One hundred fifty-five patients, referred to the Periodontal Department of Bologna University who needed periodontal surgical treatment, were recruited. The self-reported perception of the postoperative course was assessed using the following anonymous questionnaires: Italian oral health impact profile (I-OHIP-14), visual analog scale (VAS) to evaluate the intensity of the pain, and 5-point Likert scale. RESULTS: Patients reported a mean OHIP-14 total score of 9.87±8.5 (range 0-42), significantly influenced by the female sex, flap extension, and periodontal dressing. A mean VAS score of 2.96±2.39 (range 0-9) was calculated, and was found to be influenced by the presence of vertical releasing incisions and palatal flap extension. Of the 155 subjects, 40 (25.8%) patients reported bleeding as a post-surgical complication, 96 (61.9%) swelling, 105 (67.7%) eating discomfort, and 44 (28.4%) reported speech discomfort. CONCLUSIONS: Within the limitations of the nature of the present study, periodontal surgical procedures have a low impact on patients' quality of life evaluated through the OHIP-14 and VAS pain questionnaires. CLINICAL RELEVANCE: Periodontal surgical procedures are safe procedures, with a limited duration of postoperative discomfort as well as the incidence of complications.

Cigarette smoking contributes to poor oral health and dental discoloration. Therefore, stopping smoking may translate into measurable amelioration of dental shade indices. We compared dental shade parameters by digital spectrophotometry among current, former, and never smokers and verified their repeatability at 7 and 30 days. Dental shade parameters (CIE L*a*b* and corresponding whiteness index for dentistry-WID) were measured in current, former, and never smokers with a digital spectrophotometer (Vita Easyshade V) on three separate study visits: at baseline (day 0), at day 7, and day 30. Dental shade parameters were analyzed in 18 current, 18 former, and 20 never smokers. The repeatability of shade parameters was consistent in current, former, and never smokers. L*, a*, b*, and WID show significant short and long-term repeatability (p < 0.0001, by regression analyses). The mean (± SD) WID score of 13.42 (± 4.9) in current smokers was significantly lower compared to the WID score of 20.38 (± 5.3) in never smokers (p = 0.001). No significant differences were observed between current and former smokers and between former smokers and former smokers. Dental shade measurements by digital spectrophotometry were highly reproducible and showed that teeth whiteness of current smokers is substantially inferior compared to never smokers. Objective discrimination of dental shade can be a valuable regulatory science endpoint for investigating oral hygiene and dental aesthetics of consumer care products, smoking cessation medications, and tar-free tobacco products (e-cigarettes, heated tobacco products, oral nicotine products) for cigarette substitution.Clinical trial registration: the study was not registered in ClinicalTrials.gov considering that it is a pilot study, parts of a larger project with ID: NCT04649645.

OBJECTIVES: To review the available literature on patient-reported outcome measures (PROMs) following soft tissue augmentation at implant sites. MATERIALS AND METHODS: A comprehensive electronic and manual search was performed to identify clinical studies that involved soft tissue augmentation around dental implants and reported PROMs, including post-operative morbidity, painkillers intake, quality of life, aesthetics and satisfactions. RESULTS: Nineteen articles were included in the qualitative analysis. Autogenous grafts (free gingival graft and connective tissue graft), acellular dermal matrix and xenogeneic collagen matrix were utilized, either with a bilaminar- or an apically positioned flap approach. PROMs reported in the literature included perceived hardship of the procedure and pain during the surgery, post-operative morbidity, painkillers intake, number of days with discomfort, satisfaction, aesthetic evaluation, quality of life and willingness to undergo the treatment again. Most of the included studies showed similar PROMs between autogenous grafts and substitutes, in terms of post-operative morbidity, painkillers intake, quality of life, aesthetic assessment and satisfaction. Nevertheless, a trend towards lower post-operative discomfort was observed for graft substitutes. High scores for patient satisfaction and aesthetic evaluation were observed in all the interventions compared to non-grafted sites. CONCLUSIONS: PROMs represent a crucial endpoint of clinical studies evaluating the outcomes of soft tissue grafts at implant sites. Most of the studies did not find significant differences in terms of patient morbidity and painkillers between autogenous grafts and substitutes. Soft tissue grafting can enhance patient satisfaction and aesthetic evaluation compared to non-grafted sites.

OBJECTIVES: To introduce an esthetic index for assessing the outcomes of peri-implant soft tissue dehiscence/deficiency (PSTD) coverage and test its within- and between-reviewer reliability. MATERIALS AND METHODS: Photographs of 51 single PSTDs at baseline and after treatment were provided to four periodontists from three centers. The examiners were asked to rate each case at two timepoints with the Implant soft tissue Dehiscence/deficiency coverage Esthetic Score (IDES) that involved the evaluation of the post-treatment level of the soft tissue margin, peri-implant papillae height, mucosa color, and mucosa appearance (summing up to a total score of 10). Variance components analysis was conducted using multilevel regression fit in a Bayesian framework for obtaining uncertainty intervals for fractional variance contributions and intraclass correlation values (ICC) of the IDES, and for each of its four clinical variables. RESULTS: Regression models showed reproducible esthetic evaluation among the examiners (inter-reliability) and negligible intra-reviewer variability (assessment of the same case at different timepoints). The ICC for the variability in the assessment of the overall IDES was 0.86, and for the individual components ranged from 0.78 to 0.87. Additionally, there was a strong similarity between the raters' IDES values, and their subjective esthetic response, by the same raters. CONCLUSION: The IDES showed persistent judgment among the 4 reviewers, and only a slight intra-reviewer variability across timepoints. Within its limitations, this study suggests that the proposed novel score can be a reliable tool for evaluating the esthetic outcomes of PSTD coverage, which can aid in standardization of esthetic assessments following the treatment of a PSTD.

OBJECTIVES: The task of working Group 2 at the 6th Consensus Meeting of the European Association for Osseointegration was to comprehensively assess the effects of soft tissue augmentation procedures at dental implant sites on clinical, radiographic and patient-reported outcome measures (PROMs) including an overview on available outcome measures and methods of assessment. MATERIALS AND METHODS: Three systematic reviews and one critical review were performed in advance on (i) the effects of soft tissue augmentation procedures on clinical, radiographic and aesthetic outcomes, (ii) reliability and validity of outcome measures and methods of assessment and (iii) PROMs applied in clinical studies for soft tissue augmentation procedures at dental implant sites. Major findings, consensus statements, clinical recommendations and implications for future research were discussed in the group and approved during the plenary sessions. RESULTS: The four reviews predominantly revealed: Soft tissue augmentation procedures in conjunction with immediate and delayed implant placement result in superior aesthetic outcomes compared to no soft tissue augmentation in the zone of aesthetic priority. Soft tissue augmentation procedures have a limited effect on marginal bone level changes compared to implant sites without soft tissue augmentation. Clinically relevant parameters (gingival index, mucosal recession) and plaque control improve at implant sites when the width of keratinised mucosa is increased. A variety of aesthetic indices have been described with good reliability. Pink Esthetic Score and Complex Esthetic Index are the most validated aesthetic indices for single implants, though. Superimposed digital surface scans are most accurate to assess profilometric tissue changes. PROMs following soft tissue augmentation procedures have been assessed using various forms of questionnaires. Soft tissue augmentation had a limited effect on PROMs. CONCLUSIONS: Soft tissue augmentation procedures are widely applied in conjunction with implant therapy. Depending on the indication of these interventions, clinical, radiographic and aesthetic outcomes may improve, whereas the effect on PROMs is limited.

OBJECTIVE: To test the safety of a new volume-stable collagen matrix (VCMX) in combination with coronally advanced flap (CAF) for the treatment of single gingival recession. MATERIAL AND METHODS: Ten patients were treated for single RT1 gingival recession. Complete and mean root coverage, gingival thickness and keratinized tissue height, patient-reported outcome measures (PROMs), and safety were assessed up to 180 days. Descriptive statistics were used to analyze the clinical parameters. RESULTS: VCMX resulted to be safe with no serious adverse events in all patients. At 6 months, root coverage was 96.7% with 90% of defects exhibiting complete coverage. There was an increase in mean width of keratinized tissue (KT) (0.4 ± 0.8 mm) and in gingival thickness (GT) (0.4 ± 0.34 mm); however, the difference was not statistically significant compared to baseline parameters. Pain perception and pain-killer consumption were low and decreasing further at 7 days. Esthetic satisfaction for both patients and experts revealed excellent scores. CONCLUSIONS: VCMX is a safe and well-tolerated device for the treatment of single gingival recessions. In combination with CAF, it resulted in a high performance in terms of mean and complete root coverage, KT width, and GT increase. VCMX may reduce patient discomfort and post-operative morbidity. CLINICAL RELEVANCE: VCMX is a safe and stable substitute for the treatment of gingival recession in conjunction with coronally advanced technique.

Treatment of buccal gingival recession is performed for esthetic concerns, root sensitivity, root caries and cervical abrasion resulting from incorrect toothbrushing. Over the years, clinicians and researchers have improved surgical techniques to achieve surrogate end points, such as complete root coverage, gingival recession reduction or keratinized tissue increase, ignoring the input from the patient regarding the true indications for treatment. In the past few years there has been an emphasis to include patient-centered outcomes in the evaluation of root-coverage procedures. The aim of this narrative review is to describe the professional objective assessment of the esthetic results after root-coverage procedures and the patient perception of outcome in terms of esthetics, postoperative morbidity and dentinal hypersensitivity resolution after the treatment of gingival recessions. The need to align professional (surrogate) end points with patient-centered outcomes (true end points) in the future is emphasized.

The primary indication for treatment of gingival recessions is esthetics. In the last decades, patients have become increasingly more demanding in the esthetic outcome expected. In order to obtain a successful final result, periodontal plastic surgery should provide not only complete root coverage but also perfect blending in terms of color and texture. In the literature, many techniques have been demonstrated to be effective in obtaining complete root coverage, and the selection of one surgical technique over another depends on several factors related to the anatomic characteristics of the defect. The purpose of this paper was to suggest a decision-making process which starts from the clinical observation of the defects and is structured in progressive nodes that will guide the clinician through the most suitable surgical technique to achieve the ideal esthetic outcome.

Criteria for successful implants, in the rehabilitation of a single missing tooth in the esthetic area, should be determined by composite outcomes, including functional and esthetic aspects of soft tissues and the reconstruction, as well as patient-reported outcomes. This paper focuses on current methods in esthetic assessment and patient-centered/reported outcomes in single-tooth implant rehabilitation in the esthetic area. The relationship between subjective, patient-based esthetic evaluations and objective, professional-based esthetic evaluations is reviewed. In spite of increasing interest in the assessment of 'success' in implant dentistry, it is not yet possible to provide evidence-based conclusions because of the lack of consensus on a universal implant-supported crown esthetic index. There is also a need to standardize reporting of patient-centered outcomes in partially edentulous patients treated with implants.

Loss of dentition leads to functional and esthetic challenges that are determined by the anatomic features of the edentulous area. These features can complicate the prosthetic rehabilitation of such patients, especially in situations where optimal esthetic outcomes are desired. For these reasons, reconstructive plastic surgery procedures, aimed at restoring the alveolar ridge to its former dimensions, have become of great clinical interest. These reconstructive plastic surgery procedures frequently involve soft-tissue augmentation, performed to improve the quality and quantity of mucogingival tissue with the aim to achieve an ideal esthetic result. This review will focus on the description and expected outcomes of different surgical techniques for soft-tissue augmentation in edentulous areas, as described in the literature. Although more information from a larger number of studies and randomized controlled clinical trials is needed, it is possible to draw some conclusions, namely: pouch procedures are the first choice for soft-tissue augmentation, especially in high-demand esthetic areas; roll techniques are possible in shallow buccolingual soft-tissue augmentations; and onlay, inlay and combination grafts are less suitable for soft-tissue augmentation because of their poor esthetic results.
