RESUMO
BACKGROUND: Periodontitis and peri-implant diseases are chronic inflammatory conditions occurring in the mouth. Left untreated, periodontitis progressively destroys the tooth-supporting apparatus. Peri-implant diseases occur in tissues around dental implants and are characterised by inflammation in the peri-implant mucosa and subsequent progressive loss of supporting bone. Treatment aims to clean the pockets around teeth or dental implants and prevent damage to surrounding soft tissue and bone, including improvement of oral hygiene, risk factor control (e.g. encouraging cessation of smoking) and surgical interventions. The key aspect of standard non-surgical treatment is the removal of the subgingival biofilm using subgingival instrumentation (SI) (also called scaling and root planing). Antimicrobial photodynamic therapy (aPDT) can be used an adjunctive treatment to SI. It uses light energy to kill micro-organisms that have been treated with a light-absorbing photosensitising agent immediately prior to aPDT. OBJECTIVES: To assess the effects of SI with adjunctive aPDT versus SI alone or with placebo aPDT for periodontitis and peri-implant diseases in adults. SEARCH METHODS: We searched the Cochrane Oral Health Trials Register, CENTRAL, MEDLINE, Embase, two other databases and two trials registers up to 14 February 2024. SELECTION CRITERIA: We included randomised controlled trials (RCTs) (both parallel-group and split-mouth design) in participants with a clinical diagnosis of periodontitis, peri-implantitis or peri-implant disease. We compared the adjunctive use of antimicrobial photodynamic therapy (aPDT), in which aPDT was given after subgingival or submucosal instrumentation (SI), versus SI alone or a combination of SI and a placebo aPDT given during the active or supportive phase of therapy. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methodological procedures, and we used GRADE to assess the certainty of the evidence. We prioritised six outcomes and the measure of change from baseline to six months after treatment: probing pocket depth (PPD), bleeding on probing (BOP), clinical attachment level (CAL), gingival recession (REC), pocket closure and adverse effects related to aPDT. We were also interested in change in bone level (for participants with peri-implantitis), and participant satisfaction and quality of life. MAIN RESULTS: We included 50 RCTs with 1407 participants. Most studies used a split-mouth study design; only 18 studies used a parallel-group design. Studies were small, ranging from 10 participants to 88. Adjunctive aPDT was given in a single session in 39 studies, in multiple sessions (between two and four sessions) in 11 studies, and one study included both single and multiple sessions. SI was given using hand or power-driven instrumentation (or both), and was carried out prior to adjunctive aPDT. Five studies used placebo aPDT in the control group and we combined these in meta-analyses with studies in which SI alone was used. All studies included high or unclear risks of bias, such as selection bias or performance bias of personnel (when SI was carried out by an operator aware of group allocation). We downgraded the certainty of all the evidence owing to these risks of bias, as well as for unexplained statistical inconsistency in the pooled effect estimates or for imprecision when evidence was derived from very few participants and confidence intervals (CI) indicated possible benefit to both intervention and control groups. Adjunctive aPDT versus SI alone during active treatment of periodontitis (44 studies) We are very uncertain whether adjunctive aPDT during active treatment of periodontitis leads to improvement in any clinical outcomes at six months when compared to SI alone: PPD (mean difference (MD) 0.52 mm, 95% CI 0.31 to 0.74; 15 studies, 452 participants), BOP (MD 5.72%, 95% CI 1.62 to 9.81; 5 studies, 171 studies), CAL (MD 0.44 mm, 95% CI 0.24 to 0.64; 13 studies, 414 participants) and REC (MD 0.00, 95% CI -0.16 to 0.16; 4 studies, 95 participants); very low-certainty evidence. Any apparent differences between adjunctive aPDT and SI alone were not judged to be clinically important. Twenty-four studies (639 participants) observed no adverse effects related to aPDT (moderate-certainty evidence). No studies reported pocket closure at six months, participant satisfaction or quality of life. Adjunctive aPDT versus SI alone during supportive treatment of periodontitis (six studies) We were very uncertain whether adjunctive aPDT during supportive treatment of periodontitis leads to improvement in any clinical outcomes at six months when compared to SI alone: PPD (MD -0.04 mm, 95% CI -0.19 to 0.10; 3 studies, 125 participants), BOP (MD 4.98%, 95% CI -2.51 to 12.46; 3 studies, 127 participants), CAL (MD 0.07 mm, 95% CI -0.26 to 0.40; 2 studies, 85 participants) and REC (MD -0.20 mm, 95% CI -0.48 to 0.08; 1 study, 24 participants); very low-certainty evidence. These findings were all imprecise and included no clinically important benefits for aPDT. Three studies (134 participants) reported adverse effects: a single participant developed an abscess, though it is not evident whether this was related to aPDT, and two studies observed no adverse effects related to aPDT (moderate-certainty evidence). No studies reported pocket closure at six months, participant satisfaction or quality of life. AUTHORS' CONCLUSIONS: Because the certainty of the evidence is very low, we cannot be sure if adjunctive aPDT leads to improved clinical outcomes during the active or supportive treatment of periodontitis; moreover, results suggest that any improvements may be too small to be clinically important. The certainty of this evidence can only be increased by the inclusion of large, well-conducted RCTs that are appropriately analysed to account for change in outcome over time or within-participant split-mouth study designs (or both). We found no studies including people with peri-implantitis, and only one study including people with peri-implant mucositis, but this very small study reported no data at six months, warranting more evidence for adjunctive aPDT in this population group.

OBJECTIVES: To evaluate the clinical effectiveness of regenerative treatment of intrabony defects in combination with consecutive orthodontic therapy with clear aligners in stage IV (type 2) periodontitis. METHOD AND MATERIALS: Ten patients with a total of 103 intrabony defects were analyzed after regenerative surgery using collagen-deproteinized bovine bone mineral with or without collagen membrane or enamel matrix derivative followed by orthodontic therapy with clear aligners. Changes in radiographic bone level and probing pocket depths were evaluated after 1 year (T1) and at final splinting (T2) after orthodontic tooth movement. RESULTS: Mean radiographic bone level gain was significant, with 2.13 ± 1.64 mm at T1 and 3.02 ± 2.00 mm at T2. Mean probing pocket depth was significantly reduced from 5.40 ± 1.80 mm at baseline to 3.78 ± 1.73 mm at T1, and remained stable with 3.73 ± 1.70 mm at T2. Pocket closure (≤ 4 mm probing pocket depth) was accomplished in 76% of all defects. Tooth loss amounted to 2.9%. CONCLUSION: Within the limitations of the retrospective study design, the findings suggest that the interdisciplinary treatment of periodontitis stage IV by regenerative periodontal surgery and consecutive orthodontic therapy with clear aligners can lead to favorable results.

It is nowadays well accepted that chronic inflammation plays a pivotal role in tumor initiation and progression. Under this aspect, the oral cavity is predestined to examine this connection because periodontitis is a highly prevalent chronic inflammatory disease and oral squamous cell carcinomas are the most common oral malignant lesions. In this review, we describe how particular molecules of the human innate host defense system may participate as molecular links between these two important chronic noncommunicable diseases (NCDs). Specific focus is directed toward antimicrobial polypeptides, such as the cathelicidin LL-37 and human defensins, as well as S100 proteins and alarmins. We report in which way these peptides and proteins are able to initiate and support oral tumorigenesis, showing direct mechanisms by binding to growth-stimulating cell surface receptors and/or indirect effects, for example, inducing tumor-promoting genes. Finally, bacterial challenges with impact on oral cancerogenesis are briefly addressed.
RESUMO
The aim of this study was to examine the conditions of implants that had been in function for 5-17 years in stage III/IV periodontitis patients of a specialized periodontal practice. There were 83 patients (43 female/40 male, mean age 64.4 (9.69) years), with a total of 213 implants, who participated in the study. Assessments included periodontal and peri-implant probing depths, bleeding and plaque scores, and a radiographic examination. Smoking habits, participation in a supportive care program (SCP), and the Implant Disease Risk Assessment (IDRA) scores were recorded. A total of 44 patients presented with stage III periodontitis, and 39 with stage IV. In all, 85% of patients had adhered to regular SCP. On an implant/patient level, peri-implant health was found in 37.1.7% (79 implants)/24.1% (20 patients), peri-implant mucositis in 58.7% (125 implants)/66.3% (55 patients), and peri-implantitis in 4.2% (9 implants)/9.6% (8 patients). IDRA scores showed 30.5% of implants at moderate and 69.5% at high risk. The present long-term analysis shows a high prevalence of peri-implant disease in patients treated for advanced periodontitis. These findings underline the challenges involved in the long-term maintenance of oral health in stage III/IV periodontitis patients restored with dental implants.
RESUMO
Regenerative periodontal surgical procedures are an important component in the treatment of advanced periodontitis. They aim to improve the long-term prognosis of teeth that are periodontally compromised by the presence of intrabony and/or furcation defects, resulting biologically in formation of root cementum, periodontal ligament, and alveolar bone and evidenced clinically by reduction of deep pockets to maintainable probing depths and/or improvements of vertical and horizontal furcation depth. Over the last 25 years, substantial clinical evidence has been accumulated to support the value of regenerative procedures in periodontally compromised dentitions. However, treatment success requires close attention to certain factors on the level of the patient, the tooth/defect, and the operator. Ignoring these factors in case selection, treatment planning, and treatment execution will increase the risk of complications that may jeopardize clinical success and may even be considered as treatment errors. Based on the currently available evidence from clinical practice guidelines, treatment algorithms, and on expert opinion, the present article provides an overview on the main factors, which influence the outcomes of regenerative periodontal surgery and gives recommendations on how to prevent complications and treatment errors.

In stage IV periodontitis patients with pathologic tooth migration (PTM), interdisciplinary treatment includes regenerative periodontal surgery (RPS) with an application of biomaterials and orthodontic therapy (OT) to restore function, esthetics and thereby quality of life (QoL). In a 24-month randomized trial we explored the synergy between regenerative medicine and biomechanical force application. The following methods were used: Forty-three patients had been randomized to a combined treatment comprising RPS and subsequent OT starting either 4 weeks (early OT) or 6 months (late OT) post-operatively. Clinical periodontal parameters and oral health-related QoL (GOHAI) were recorded up to 24 months. We obtained the following results: Mean clinical attachment gain (∆CAL ± SD) was significantly higher with early OT (5.96 ± 2.1 mm) versus late OT (4.65 ± 1.76 mm) (p = 0.034). Pocket closure (PPD ≤ 4 mm) was obtained in 91% of defects with early OT compared to 90% with late OT. GOHAI-scores decreased significantly from 26.1 ± 7.5 to 9.6 ± 4.7 (early OT) and 25.1 ± 7.1 to 12.7 ± 5.6 (late OT). Inconclusion, teeth severely compromised by intrabony defects and PTM can be treated successfully by RPS followed by early OT with the advantage of an overall reduced treatment time. As a result of the combined periodontal-orthodontic therapy, the oral health-related QoL of patients was significantly improved. Early stimulation of wound healing with orthodontic forces had a favorable impact on the outcomes of regenerative periodontal surgery.
RESUMO
BACKGROUND: The recently published Clinical Practice Guidelines (CPGs) for the treatment of stages I-IV periodontitis provided evidence-based recommendations for treating periodontitis patients, defined according to the 2018 classification. Peri-implant diseases were also re-defined in the 2018 classification. It is well established that both peri-implant mucositis and peri-implantitis are highly prevalent. In addition, peri-implantitis is particularly challenging to manage and is accompanied by significant morbidity. AIM: To develop an S3 level CPG for the prevention and treatment of peri-implant diseases, focusing on the implementation of interdisciplinary approaches required to prevent the development of peri-implant diseases or their recurrence, and to treat/rehabilitate patients with dental implants following the development of peri-implant diseases. MATERIALS AND METHODS: This S3 level CPG was developed by the European Federation of Periodontology, following methodological guidance from the Association of Scientific Medical Societies in Germany and the Grading of Recommendations Assessment, Development and Evaluation process. A rigorous and transparent process included synthesis of relevant research in 13 specifically commissioned systematic reviews, evaluation of the quality and strength of evidence, formulation of specific recommendations, and a structured consensus process involving leading experts and a broad base of stakeholders. RESULTS: The S3 level CPG for the prevention and treatment of peri-implant diseases culminated in the recommendation for implementation of various different interventions before, during and after implant placement/loading. Prevention of peri-implant diseases should commence when dental implants are planned, surgically placed and prosthetically loaded. Once the implants are loaded and in function, a supportive peri-implant care programme should be structured, including periodical assessment of peri-implant tissue health. If peri-implant mucositis or peri-implantitis are detected, appropriate treatments for their management must be rendered. CONCLUSION: The present S3 level CPG informs clinical practice, health systems, policymakers and, indirectly, the public on the available and most effective modalities to maintain healthy peri-implant tissues, and to manage peri-implant diseases, according to the available evidence at the time of publication.

BACKGROUND: This study aimed to evaluate the long-term effectiveness of regenerative treatment of intra-bony defects in combination with consecutive orthodontic therapy (OT) in stage IV periodontitis. METHODS: Twenty-two patients with a total of 256 intra-bony defects were analyzed after regenerative surgery followed by OT initiated 3 months later. Changes in radiographic bone level (rBL) and probing pocket depths (PPD) were evaluated after 1 year (T1), final splinting (T2), and 10 years (T10). RESULTS: Mean rBL gain was significant with 4.63 mm (±2.43 mm) after 1 year (T1), 4.19 mm (±2.61 mm) at final splinting (T2), and 4.48 mm (±2.62 mm) after 10 years (T10). Mean PPD was significantly reduced from 5.84 mm (±2.05 mm) at baseline to 3.19 mm (±1.23 mm) at T1, to 3.07 mm (±1.23 mm) at T2, and to 2.93 mm (±1.24 mm) at T10. Pocket closure (PPD ≤ 4 mm) was achieved in 90% of all defects. Tooth loss amounted to 4.5%. CONCLUSIONS: Within the limitations of this retrospective study design, these 10-year findings suggest that in motivated and compliant patients with stage IV periodontitis and in need of OT an inter-disciplinary treatment can lead to favorable and stable long-term results.

AIM: To evaluate the efficacy of professionally administered chemical agents as an adjunctive treatment to sub-marginal instrumentation (SMI) in the therapy of peri-implant mucositis. MATERIALS AND METHODS: The primary outcome criteria were reduction in bleeding on probing (BOP), whereas resolution of disease, elimination of suppuration, including suppuration on probing, reduction of peri-implant probing pocket depth, reduction of plaque, and patient-reported outcome measures were considered as secondary outcome parameters. A literature search was performed on three electronic databases (01/1980 to 05/2022) focused on clinical studies with at least 3 months of follow-up, and meta-analyses were performed when appropriate. RESULTS: From a total of 139 publications, 40 articles were identified for full-text reading, and 5 randomized controlled clinical trials (RCTs) on antimicrobial photodynamic therapy (aPDT), 1 RCT on chlorhexidine (CHX), and 1 RCT on sodium hypochlorite (NaOCl) were included. Three studies had a low risk of bias and four had a mid-level (some concerns) risk of bias. The application of aPDT, 0.95% NaOCl, or 0.12% CHX as an adjunctive treatment to SMI showed no difference in changes in BOP and PD compared with SMI alone (p > .05). CONCLUSIONS: Within the limitations of this review and based on a low level of evidence from seven RCTs, it is concluded that the professional adjunctive topical application of aPDT, 0.95% NaOCl, and 0.12% CHX may not be effective to improve changes for BOP and PD when compared with SMI alone.

(1) Background: Severely compromised teeth affected by endo-periodontal lesions are often assigned a "hopeless" prognosis, however, there is only limited evidence available. (2) Methods: In a retrospective study, we evaluated the long-term effectiveness of combined endodontic and regenerative periodontal therapy in teeth with advanced endo-periodontal lesions: 35 patients (age 47-83 years) with a total of 39 teeth diagnosed with grade 3 endo-periodontal lesions were treated by endodontists using an operating microscope followed by regenerative periodontal surgery. (3) Results: Changes in radiographic bone levels (rBl) and probing pocket depths (PPDs) were evaluated after 1 year (T1) and up to 7 years postoperatively (Tfinal). Mean rBL gain was significant with 4.87 ± 3.47 mm after 1 year (T1) and stable results with a mean rBL gain of 4.70 ± 3.37 mm at Tfinal. Mean PPD was significantly reduced from 9.74 ± 2.05 mm at baseline to 5.04 ± 1.61 mm at T1 and to 4.87 ± 2.32 mm at Tfinal. Tooth loss amounted to 10.3% (n = 4) and was due to root fracture. (4) Conclusion: The results suggest that the combined endodontic and regenerative periodontal therapy of endo-periodontal lesions of "hopeless" teeth can lead to favorable long-term results with tooth retention for up to 7 years.
RESUMO
The periodontal microbiota is ecologically diverse and may facilitate colonization by bacteria of enteric origin (Enterobacteriaceae, Enterococci) and co-infections with Candida albicans, possibly producing subgingival biofilms with high antimicrobial tolerance. This retrospective surveillance study followed periodontitis-associated superinfection profiles in a large patient sample. From 2008 to 2015, biofilm samples from deep periodontal pockets were collected from a total of 16,612 German adults diagnosed with periodontitis. The presence of selected Enterobacteriaceae, Enterococci, and Candida albicans was confirmed in overnight cultures. Antimicrobial susceptibility of these clinical isolates was tested by disk diffusion with antibiotics routinely used for treatment of oral infections, e.g., amoxicillin (AML), amoxicillin/clavulanic acid (AMC), doxycycline (DO), and ciprofloxacin (CIP). The mean annual prevalence of patients harboring Enterobacteriaceae in periodontal plaques was 11.5% in total and ranged from 2.5% for Enterobacter cloacae to 3.6% for Klebsiella oxytoca, 1.1% for Klebsiella pneumoniae, 2.8% for Serratia marcescens, and 1.5% for Serratia liquefaciens. In comparison, the mean detection rates for microbiota typically found in the oral cavity were higher, e.g., 5.6% for Enterococcus spp. and 21.8% for Candida albicans. Among the Enterobacteriaceae, species harboring intrinsic resistance to AML (Enterobacter spp., Klebsiella spp., Serratia spp.) were predominant. Non-susceptibility to AMC was observed for Serratia spp. and Enterobacter cloacae. By contrast, Enterococcus spp. only showed non-susceptibility to DO and CIP. Trends for increasing resistance were found to AML in Serratia liquefaciens and to DO in Enterococcus spp. Trend analysis showed decreasing resistance to AMC in Serratia liquefaciens and Klebsiella oxytoca; and to DO in Serratia marcescens, liquefaciens, and Enterobacter cloacae. This study confirms the low but consistent presence of Enterobacteriaceae and Enterococci among the subgingival microbiota recovered from periodontitis specimen. Although their pathogenetic role in periodontal lesions remains unclear, their presence in the oral cavity should be recognized as a potential reservoir for development and spread of antibiotic resistance in light of antibiotic usage in oral infections.
RESUMO
Peri-implantitis is caused by a bacterial challenge; therefore, anti-infective treatment strategies should be employed to manage the disease. As nonsurgical approaches demonstrate limited efficacy in most cases of peri-implantitis, surgical interventions are often required. Treatment outcomes improve following access flap surgery, with or without adjunctive resective and/or augmentation measures. Whereas nonaugmentative therapies (ie, access flap surgery and resective techniques) primarily aim to resolve inflammation and arrest further disease progression, augmentation approaches also seek to regenerate the bony defect and achieve reosseointegration. Currently, limited evidence supports the superiority of augmentative surgical techniques for peri-implantitis treatment over nonaugmentation methods, and human histologic evidence for reosseointegration is sparse. For patients involved in regular postoperative maintenance programs, success of peri-implantitis surgical treatment based on various definitions of success was obtained in over half of the cases after 5-7 years. Despite surgical treatment, cases of further disease progression that required retreatment or led to implant loss were reported.

Resumen Antecedentes: La clasificación de la periodontitis recientemente introducida en el World Workshop de 2017, que incorpora estadios y grados de la enfermedad, tiene por objeto vincular la clasificación de la enfermedad con los enfoques preventivos y terapéuticos, ya que no solo describe su gravedad y el alcance, sino también el grado de complejidad y el riesgo de un individuo. Por lo tanto, es necesario contar con directrices clínicas basadas en la evidencia que ofrezcan recomendaciones para tratar la periodontitis. Objetivo: El objetivo del presente proyecto fue desarrollar una Guía de Práctica Clínica (CPG, por sus siglas en inglés, clinical practice guideline) de nivel S3 para el tratamiento de la periodontitis en los estadios I-III. Material y métodos: Estas CPG S3 se elaboraron bajo los auspicios de la Federación Europea de Periodoncia (EFP), siguiendo la orientación metodológica de la Asociación de Sociedades Médico-Científicas de Alemania y la estructura Grading of Recommendations Assessment, Development and Evaluation (GRADE). El proceso, riguroso y transparente, incluyó la síntesis de las investigaciones relevantes en 15 revisiones sistemáticas encargadas de manera específica, la evaluación de la calidad y la solidez de la evidencia, la formulación de recomendaciones específicas, así como lograr un acuerdo, sobre esas recomendaciones, por parte de expertos destacados y una amplia base de partes interesadas. Resultados: Estas CPG S3 abordan el tratamiento de la periodontitis (estadios I, II y III) utilizando un enfoque gradual preestablecido del tratamiento que, según el estadio de la enfermedad, debe ser incremental, incluyendo en cada caso diferentes intervenciones. Se llegó a un acuerdo sobre las recomendaciones relativas a las diferentes intervenciones, dirigidas a: i) cambios de comportamiento, control de biofilm supragingival, inflamación gingival y factores de riesgo; ii) instrumentación supragingival y subgingival, con y sin tratamientos coadyuvantes; iii) diferentes tipos de intervenciones quirúrgicas periodontales; y iv) el mantenimiento periodontal necesario para extender los beneficios a lo largo del tiempo. Conclusión: Esta Guía S3 informa a los clínicos, a los sistemas de salud, a los encargados de formular políticas sanitarias e, indirectamente, al público, sobre las modalidades disponibles y más eficaces para tratar la periodontitis y mantener una dentición sana durante toda la vida, de acuerdo con la evidencia disponible en el momento de su publicación.

AIM: To compare the outcomes after early (4 weeks post surgery) or late (6 months post surgery) orthodontic therapy (OT) following regenerative surgery of intra-bony defects (IDs). MATERIALS AND METHODS: In a multi-center, parallel-group, randomized clinical trial, 43 patients with stage IV periodontitis were randomized to receive either early (n = 23) or late OT (n = 20) following regenerative surgery of IDs. Primary outcome was change in clinical attachment level (CAL) in one target ID at 12 months after surgery. Secondary outcomes were changes of probing pocket depth (PPD), bleeding on probing (BOP), and frequency of pocket closure. RESULTS: No statistically significant differences between groups could be observed for CAL gain (5.4 mm [±2.1 mm] for early; 4.5 mm [±1.7 mm] for late OT). PPD was reduced by 4.2 mm (±1.9 mm) in the early group and by 3.9 mm (±1.5 mm) in the late group (p > .05). Pocket closure (PPD ≤ 4 mm) was obtained in 91% of defects in early compared to 85% in late OT. CONCLUSION: In the inter-disciplinary treatment of periodontitis stage IV, OT can be initiated already 4 weeks after regenerative surgery of IDs with favourable results, thus reducing the overall treatment time.

AIM: Evaluation of the effectiveness of regenerative treatment of intra-bony defects in combination with consecutive orthodontic tooth movements in stage IV periodontitis. MATERIAL AND METHODS: A total of 526 intra-bony defects in 48 patients were analysed after regenerative therapy using collagen-deproteinized bovine bone mineral with or without collagen membrane or enamel matrix derivative followed by orthodontic tooth movement initiated 3 months after surgery. Changes in radiographic bone levels (BL) and probing pocket depths (PPD) were evaluated after 1 year and up to 4 years. RESULTS: Tooth loss amounted to 0.57%. Mean BL gain was 4.67 mm (±2.5 mm) after 1 year and 4.85 mm (±2.55 mm) after up to 4 years. Mean PPD was significantly reduced from 6.00 mm (±2.09 mm) at baseline to 3.45 mm (±1.2 mm) after 1 year, and to 3.12 mm (±1.36 mm) after 2-4 years. Pocket closure (PPD ≤4 mm) was accomplished in 87% of all defects. Adjunctive antibiotic therapy did not show any statistically significant impact on treatment outcomes. CONCLUSIONS: Within the limits of this retrospective study design, the findings suggest that the combination of regenerative treatment and consecutive orthodontic tooth movements resulted in favourable results up to 4 years.

BACKGROUND AND OBJECTIVE: Systemic antibiotics (AB) are often used in conjunction with regenerative/reconstructive periodontal surgery of intrabony defects and furcations; however, their potential benefits have not been systematically assessed. MATERIALS AND METHODS: Data were retrieved from two recent systematic reviews (a total of 105 randomized clinical trials (RCTs) on clinical and radiographic outcomes in intrabony defects (ID) and molars with furcation involvement (FI) treated by surgical access with regenerative techniques. Pair-wise meta-analysis of RCTs with and without AB was performed. Meta-regressions from single-arm (subgroup) RCTs including study arms with or without adjunctive AB were also conducted. RESULTS: No statistically significant benefits of systemic AB with regard to PPD, CAL and bone gain were detected in ID by pair-wise meta-analysis. Meta-regression revealed increased PPD reduction (-0.91 mm, 95% CI = -1.30; -0.51, p < 0.001), CAL gain (-0.92 mm, 95% CI = -1.32; -0.52, p < 0.001) and bone gain (-1.08 mm, 95% CI = -1.63; -0.53, p < 0.001) in ID but not in any of the outcomes in FI for arms treated with AB vs. study arms treated with no AB. No clear differences in adverse events were detected between AB and non-AB groups. CONCLUSION: There is only weak indirect evidence that AB may provide additional benefits in terms of clinical improvements in the regenerative/reconstructive periodontal surgery of intrabony defects and no evidence for a benefit in furcations. Until new data are gained and in the context of antibiotic stewardship, it may be questionable to justify the adjunctive use of systemic antibiotics.
RESUMO
AIM: To evaluate the outcomes following surgical periodontal treatment and root surface decontamination by means of air polishing using an erythritol powder or conventional mechanical root debridement. MATERIAL AND METHODS: Thirty systemically healthy patients (44.38 ± 8.2 years old, 11 smokers, 19 women) diagnosed with periodontitis stages III-IV were included. Each patient, with one single-rooted tooth, with one probing pocket depth (PD) ≥ 6 mm associated with horizontal bone loss, was treated by means of simplified papilla preservation flap (SPPF) and randomized to either test treatment (careful removal of the calculus with the tip of a blade, air polishing of the root surfaces with erythritol) or to the control group (scaling and root planing with hand curettes, ultrasonic instruments). PD, clinical attachment (CAL), bone sounding (BS), and radiographic bone level (BL) were evaluated at baseline and 12 months postsurgically. RESULTS: Twenty-seven patients completed the 12-month follow-up (test: n = 14, control: n = 13). In both groups, statistically significant improvements were obtained (p < 0.05, mean CAL gain/PD reduction: test, 2.50 ± 1.60 mm/3.00 ± 0.96 mm; control, 2.85 ± 1.21 mm/3.38 ± 1.12 mm). No statistically significant differences were observed between the groups for any of the investigated parameters (p < 0.05). CONCLUSION: Within their limits, the present results indicate that the use of air polishing with an erythritol powder during periodontal surgery may represent a valuable minimally invasive adjunct following calculus removal by means of hand and ultrasonic instruments or a valuable alternative to these, for root surfaces without calculus. CLINICAL RELEVANCE: The use of air polishing with an erythritol powder during periodontal surgery appears to represent a valuable minimally invasive adjunct following calculus removal by means of hand and ultrasonic instruments or a valuable alternative to these, for root surfaces without calculus.

OBJECTIVES: The aim of this systematic review and meta-analysis was to compare the use of platelet-rich fibrin (PRF) with other commonly utilized treatment modalities for root coverage procedures. MATERIALS AND METHODS: The eligibility criteria comprised randomized controlled trials (RCTs) comparing the performance of PRF with that of other modalities in the treatment of Miller class I or II (Cairo RT I) gingival recessions. Studies were classified into 5 categories as follows: (1) coronally advanced flap (CAF) alone vs CAF/PRF, (2) CAF/connective tissue graft (CAF/CTG) vs CAF/PRF, (3) CAF/enamel matrix derivative (CAF/EMD) vs CAF/PRF, (4) CAF/amnion membrane (CAF/AM) vs CAF/PRF, and (5) CAF/CTG vs CAF/CTG/PRF. Studies were evaluated for percentage of relative root coverage (rRC; primary outcome), clinical attachment level (CAL), keratinized mucosa width (KMW), and probing depth (PD) (secondary outcomes). RESULTS: From 976 articles identified, 17 RCTs were included. The use of PRF statistically significantly increased rRC and CAL compared with CAF alone. No change in KMW or reduction in PD was reported. Compared with PRF, CTG resulted in statistically significantly better KMW and RC. No statistically significant differences were reported between the CAF/PRF and CAF/EMD groups or between the CAF/PRF and CAF/AM groups for any of the investigated parameters. CONCLUSIONS: The use of CAF/PRF improved rRC and CAL compared with the use of CAF alone. While similar outcomes were observed between CAF/PRF and CAF/CTG for CAL and PD change, the latter group led to statistically significantly better outcomes in terms of rRC and KTW. In summary, the use of PRF in conjunction with CAF may represent a valid treatment modality for gingival recessions exhibiting adequate baseline KMW. CLINICAL RELEVANCE: The data indicate that the use of PRF in conjunction with CAF statistically significantly improves rRC when compared with CAF alone but did not improve KMW. Therefore, in cases with limited baseline KMW, the use of CTG may be preferred over PRF.

AIMS: To introduce a novel therapeutic approach for the treatment of furcation-involved maxillary molars by vital root resection and report longer-term outcomes of a case series. METHODS: Eleven patients with 15 maxillary molars affected by double/triple class II (n = 10) or single/double class III (n = 5) furcation defects and advanced vertical bone loss around one root participated. Teeth were treated with deep pulpotomy using a calcium silicate-based cement. After 4 weeks, the affected roots were removed by periodontal microsurgery and processed for histological evaluation of the pulp. All patients were enrolled into a supportive periodontal care programme. During the follow-up period, assessments of tooth sensitivity, response to percussion, mobility, pocket probing depth (PPD) and bleeding on probing (BOP) were made, periapical radiographs obtained and patient-reported outcomes collected. RESULTS: All teeth remained sensitive to pulp testing. After 1 year and 3-7 years of follow-up, PD was ≤5 mm at all resected teeth. Furcation status was much improved. Neither increasing mobility nor clinical or radiographic signs of periapical pathology were observed throughout the individual observation period. All patients were pleased with the result of therapy. Histologic sections revealed a functional dentin-pulp complex. CONCLUSIONS: This case series demonstrates the possibility of maintaining severely furcation-involved molars by vital root resection for up to 7 years. Root canal therapy and its associated costs and complications can thus be avoided.

BACKGROUND: Between 1998 and 2015, we report on the survival of congenital diaphragmatic hernia (CDH)-infants presenting with symptoms within the first 24 h of life, treated at Odense University Hospital (OUH), a tertiary referral non-extracorporeal membrane oxygenation (ECMO) hospital for paediatric surgery. METHODS: We performed a retrospective cohort study of prospectively identified CDH-infants at our centre. Data from medical records and critical information systems were obtained. Baseline data included mode of delivery and infant condition. Outcome data included 24-h, 28-day, and 1 year mortality rates and management data included intensive care treatment, length of stay in the intensive care unit, time of discharge from hospital, and surgical intervention. Descriptive analyses were performed for all variables. Survivors and non-survivors were compared for baseline and treatment data. RESULTS: Ninety-five infants were identified (44% female). Of these, 77% were left-sided hernias, 52% were diagnosed prenatally, and 6.4% had concurrent malformations. The 28-day mortality rate was 21.1%, and the 1 year mortality rate was 22.1%. Of the 21 non-survivors, nine died within the first 24 h, and 10 were sufficiently stabilised to undergo surgery. A statistically significant difference was observed between survivors and non-survivors regarding APGAR score at 1 and 5 min., prenatal diagnosis, body length at birth, and delivery at OUH. CONCLUSIONS: Our outcome results were comparable to published data from other centres, including centres using ECMO.
