Aim This randomized controlled clinical trial evaluated the effects of an adjunctive single application of antimicrobial photodynamic therapy (aPDT) in Surgical Periodontal Treatment (ST) in patients with severe chronic periodontitis (SCP). Material and Methods In a split-mouth design, 20 patients with SCP were treated with aPDT+ST (Test Group, TG) or ST only (Control Group, CG). aPDT was applied in a single episode, using a diode laser and a phenothiazine photosensitizer. All patients were monitored until 90 days after surgical therapy. Levels of 40 subgingival species were measured by checkerboard DNA-DNA hybridization at baseline, 60 and 150 days. Clinical and microbiological parameters were evaluated. Results In deep periodontal pockets depth (PPD ≥ 5 mm), Test Group presented a significantly higher decrease in PPD than Control Group at 90 days after surgical therapy (p

Aim This double-blind, placebo-controlled clinical study compared multiple applications of the antimicrobial photodynamic therapy (aPDT) treatment protocol, to systemic doxycycline as adjuvant to scaling and root planing (SRP) on type 2 diabetic patients on clinical, systemic and immune-inflammatory outcomes. Materials and Methods Thirty patients with Hba1c >7% were allocated in two groups, SRP + Doxy (n = 15) using systemic doxycycline 100 mg/day (14 days) and SRP + aPDT (n = 15) with multiple applications (0, 3, 7 and 14 days). Primary outcome was glycated haemoglobin levels (HbA1c). Clinical parameters: plaque score (PS), bleeding on probe, probing depth, suppuration, gingival recession, and clinical attachment level, percentage of pockets with desired clinical endpoint were measured at baseline and 3 months after therapy. Cytokine profile was assessed at 0, 1 and 3 month to measure IL1-β, TNF-α and TGF-β on gingival crevicular fluid. Results No significant difference was detected on HbA1c, between treatments. The SRP + aPDT group showed advantage on reducing moderate pockets in single-rooted teeth at 3 months. SRP + aPDT presented better results at 3 months on IL1-β levels. There were no significant differences between TNF-α and TGF-β. Conclusions Both treatments improved clinical and systemic outcomes (Hba1c). SRP + aPDT performed better in moderate probing pocket depth on single-rooted teeth, reduced favourably inflammation in short term, and may be an alternative to systemic antibiotics.

Aim To evaluate the influence of gingival thickness and bone grafting on buccal bone plate remodelling after immediate implant placement in sockets with thin buccal bone, using a flapless approach. Materials and Methods The gingiva of eight dogs was thinned at one side of the mandible, mandibular premolars were extracted without flaps, and four implants were installed on each side at 1.5 mm from the buccal bone. The sites were randomly assigned into: TG (test group) = thin gingiva; TG + GM (TG with grafting material); CG (control group) = normal gingiva; and CG + GM (CG with grafting material). After 12 weeks the dogs were sacrificed and the samples were processed for histological analysis. Results All animals exhibited a thin buccal bone initially. In all the experimental groups the buccal gap was filled with newly formed bone and the buccal bone level was slightly apical to the implant shoulder. There were no statistically significant differences among the groups for the histomorphometric parameters. Conclusions The thickness of the buccal bone was a fundamental factor in buccal bone plate resorption, even with flapless implantation. The gingival thickness or the addition of a biomaterial in the gap did not influence the results.

Background Several approaches have been used to counteract alveolar bone resorption after tooth extraction. Purpose The aim of the present study was to evaluate the influence of gingival thickness and bone grafting on buccal bone remodeling in extraction sockets with thin buccal bone, using a flapless approach. Materials and methods The gingiva of 8 dogs was thinned at one side of the mandible and mandibular premolars were extracted without flaps. The sockets were randomly assigned to the test group (thin gingiva) (TG), the test group with grafting material TG + GM, the control group (normal gingiva) (CG), or the control group with grafting material CG + GM. Ground sections were prepared from 12-week healing biopsies, and histomorphometry and fluorescence analysis were performed. Results In the groups with thin gingiva, numerically greater buccal bone loss was observed, while there were no differences between grafted and nongrafted sites. A numerically higher rate of mineralization was observed for the grafted sites, as compared with the nongrafted sites, at 12 weeks. Conclusions A thin buccal bone plate leads to higher bone loss in extraction sockets, even with flapless surgery. The gingival thickness or the use of a graft material did not prevent buccal bone resorption in a naturally thin biotype, but modified the mineralization process.

Subepithelial connective tissue graft (SCTG) has been extensively used for a variety of clinical applications. However, the surgical procedure may not allow control of graft thickness. The purpose of this case series is to illustrate a modification to the single incision palatal harvesting technique in order to control the SCTG thickness without increasing patient discomfort. Fifty cases from thirty systemically and periodontally healthy patients with at least one multiple gingival recession were treated with coronally advanced flaps combined with a SCTG. The palatal area served as the donor site, from where a single perpendicular incision was made to obtain a full thickness flap. Next, 1-2 mm of the flap was elevated and dissected to obtain a partial thickness flap. The graft remained attached to the full-partial thickness flap. After determining the desired SCTG thickness, the graft was harvested from the palatal flap. The patients healed uneventfully at 7 days postoperatively and primary closure was obtained for all palatal donor sites. The SCTG length and width varied depending on the needs of each case, but the SCTG thickness was well controlled with only 0.24 mm standard deviation. The suggested modification granted control of the SCTG dimensions and achieved complete wound closure within a week. O enxerto de tecido conjuntivo (ETC) tem sido amplamente utilizado para várias aplicações clínicas. Entretanto, o procedimento cirúrgico pode não permitir o controle da espessura do enxerto gengival. O objetivo deste relato de casos seriados é descrever uma nova técnica cirúrgica que modifica a técnica de incisão única para remoção de enxerto gengival, permitindo o controle da espessura do ETC sem aumentar o desconforto do paciente. Cinquenta casos foram realizados em trinta pacientes sistemicamente e periodontalmente saudáveis, que apresentavam pelo menos uma retração gengival múltipla, a qual foi tratada pela técnica de retalho avançado coronalmente combinada com ETC. O palato serviu como área doadora, uma incisão perpendicular foi realizada para criar um retalho total. Em seguida 1-2 mm do retalho foi elevado e dissecado para obter um retalho parcial. O ETC permaneceu retido no retalho total-parcial. Depois de determinar qual a espessura desejada do ETC, o enxerto foi removido do palato. Os pacientes apresentaram cicatrização sem complicações em 7 dias, com fechamento da ferida por primeira intenção em todos os casos. A largura e comprimento do ETC variaram conforme a necessidade de cada caso clínico, mas a espessura do ETC foi bem controlada, com apenas 0,24 mm de desvio padrão. A sugestão de modificação de técnica cirúrgica para remoção de ETC permite controlar as dimensões do ETC e fechamento da ferida por primeira intenção em 7 dias.

- Abstract
Objetivo: Próteses subgengivais aumentam a incidência de inflamação gengival, principalmente em periodontos delgados, culminando com o desenvolvimento de retrações gengivais em dentes e implantes. A proposta deste trabalho foi avaliar se o aumento da espessura gengival pode prevenir a formação de retrações gengivais. Materiais e Métodos: Modelo de boca dividida foi utilizado em 8 cães, retalho dividido foi realizado para inserir a matriz colágena suína (MCS) para aumento da espessura gengival e após três meses, próteses subgengivais foram instaladas para gerar inflamação gengival e depois de três meses os animais foram sacrificados. Os grupos: Grupo 1 (G1): MCS adaptada na região de Pré-molar 2 (P2), Pré-molar 3 (P3) e Pré-molar 4 (P4), com próteses subgengivais; Grupo 2 (G2): sem MCS na região de P2, P3 e P4, com próteses subgengivais; Grupo 3 (G3): controle do grupo 1, MCS adaptada na região de Pré-molar 1 (P1), sem próteses e Grupo 4 (G4): controle do grupo 2, sem MCS na região de P1 e sem próteses. Foram realizadas medidas clínicas de espessura e altura do tecido gengival queratinizado, profundidade de sondagem e nível clínico de inserção em três tempos (antes do aumento gengival, antes da instalação das próteses e após o sacrifício). Análise imunohistoquímica foi realizada para detectar a presença de células de defesa e padrão de queratinização gengival. Análise histomorfométrica foi realizada para quantificar as diferenças dos tecidos duros e moles entre os diferentes grupos de tratamento. Resultados: Durante os períodos de avaliação não houve variação na altura do tecido queratinizado entre os grupos, no entanto, G1 e G2 apresentaram maior espessura gengival quando comparados a G3 e G4. A profundidade de sondagem foi superior em G3 e G4 quando comparada a G1 e G2. Houve perda de inserção clínica somente em G1 e G2. As análises histomorfométricas para tecido mole e duro confirmaram os resultados clínicos. A análise imunohistoquímica não encontrou diferenças na contagem das células de defesa. Conclusão: A MCS foi capaz de aumentar a espessura gengival e prevenir a ocorrência de retrações gengivais em dentes que receberam próteses subgengivais em modelo experimental canino. Aim: Subgingival prosthesis increases the gingival inflammation incidence, especially in thin gingival biotype, leading to the development of gingival recessions. The purpose of this study was to evaluate whether the increase in gingival thickness can prevent the formation of gingival recession. Materials and Methods: Eight dogs received porcine collagen matrix to increase gingival thickness, which was then followed by subgingival prosthesis placement in order to generate gingival inflammation. Group 1: gingival thickness increase from second to fourth premolars, using subgingival prostheses; Group 2: subgingival prosthesis placement from second to fourth molars; Group 3: gingival thickness increase in the first premolar, no prostheses; Group 4: control. Clinical measurements of gingival thickness and height, clinical probing depth and clinical attachment levels were performed. Immunohistochemical analyses were performed to detect defense cells, keratinization patterns and differences between soft and mineralized tissues. Results: There was no variation in keratinized tissue height. Thicker gingiva was encountered in Groups 1 and 2, which developed gingival recession, which did not occur in Groups 3 and 4. Probing depth was more pronounced in Groups 3 and 4. Histomorphometric analysis for soft and mineralized tissues confirmed clinical findings. Immunohistochemical analysis did not show differences in defense cell counting. Conclusion: The increase in gingival thickness may minimize gingival recessions when associated with subgingival prosthesis.

The aim of this study was to analyze through clinical and histomorphometric parameters the use of acellular dermal matrix (ADM) with or without mineralized bone allograft (AB) on bone formation in human alveoli after a 6- to 8-month healing period. A total of 19 patients in need of extraction of the maxillary anterior teeth were selected and randomly assigned to the test group (ADM plus AB) or to the control group (ADM only). Clinical and histomorphometric measurements and histologic analysis were recorded 6 to 8 months after ridge preservation procedures. Clinical parameters and amount of mineralized and nonmineralized tissue were measured and analyzed. In the clinical measurements, the test group showed reduced bone loss in the buccopalatal dimension after 6 to 8 months (intragroup analysis P < .01). Histologic findings showed higher percentages of mineralized tissue and lower percentages of nonmineralized tissue in the test group when compared with the control group (P < .05). In this randomized controlled clinical and histomorphometric study in humans, acellular dermal matrix in association with mineralized bone allograft reduced alveolar bone loss in the anterior maxillae both in height and width after a follow-up period of 6 to 8 months.

Objective Soft tissues and buccal bone plate remodeling after immediate implantation in sockets with thin buccal bone, using the flapless approach with or without bone graft into the buccal gap, was compared between sites with thin and normal gingiva. Material and methods Eight dogs had the gingiva of one side of the mandible thinned, the mandibular premolars were extracted without flaps, and 4 implants were installed in each side, positioned 1.5 mm from the buccal bone. The sites were randomly assigned into: TG (test group) = thin gingiva; TG + GM (TG with grafting material); CG (control group) = normal gingiva; and CG + GM (CG with grafting material). Buccal bone thickness (BBT), thickness of keratinized tissue (TKT), alveolar thickness (AT), gingival recession (GR), and probing depth (PD) were clinically evaluated. Within 12 weeks the dogs were sacrificed and the samples were analyzed by micro-computerized tomography. Results A thin BBT was observed in all the dogs. The presurgical procedures reduced TKT in the test group, with minimal changes of the AT. There were no statistically significant differences among the groups for the clinical parameters and the tomographic analysis showed similar linear and tri-dimensional bone reduction in all the groups. Conclusion The thickness of the buccal bone was a fundamental factor in buccal bone plate resorption, even with flapless implantation. The decrease in gingival thickness or the addition of a biomaterial in the gap did not influence the results.

The base of systematic reviews available for gingival recession treatment the use of CAF alone or in association with allogeneic, xenogeneic, or alloplastic biomaterials (e.g., matrix grafts or enamel matrix derivative) has been described as being less painful and more comfortable, due to the need of only one surgical site [1–7]. Conversely, it has been demonstrated that use of SCTG, FGG, and nonabsorbable membranes has been associated with increased morbidity and some complications, such as postoperative pain, bleeding and swelling during the early phase of healing (Fig. 4.1a–c), and membrane exposure/contamination [1–7].

The aim of this randomized controlled clinical study is to investigate whether a modified surgical technique could provide better results for root coverage and greater amounts of keratinized tissue (KT) with the acellular dermal matrix graft (ADMG).Fifteen bilateral Miller Class I or II gingival recessions (GRs) were selected. The recessions were treated and assigned randomly to the test group (TG), and the contralateral recessions were assigned to the control group (CG). The ADMG was used in both groups with differences in the graft positioning between them. The following clinical parameters were measured before the surgeries and after 12 months: 1) probing depth; 2) relative clinical attachment level; 3) GR; 4) thickness of KT (TKT); and 5) KT width. A new parameter, the GR area (GRA), was measured in standardized photographs using a special device and software.There was no significant difference between groups in KT width and TKT parameters at the 12-month postoperative period. However, there was a significant difference between the gains in GR (ΔGR) and GRA (ΔGRA), favoring the TG after 12 months. The TG presented ΔGR = 3.04 ± 0.29 mm and ΔGRA= 38,919 ± 9,238 pixel square values (pix(2)), and the CG presented ΔGR= 2.61 ± 0.41 mm and ΔGRA= 22,245 ± 9,334 pix(2) (P0.05 and0.001, respectively).Both techniques were successful. The TG treatment was more effective in reducing GR and GRA. The flap and graft position may be of importance in root coverage procedures outcome.

Several approaches have been used to counteract alveolar bone resorption after tooth extraction.The aim of the present study was to evaluate the influence of gingival thickness and bone grafting on buccal bone remodeling in extraction sockets with thin buccal bone, using a flapless approach.The gingiva of 8 dogs was thinned at one side of the mandible and mandibular premolars were extracted without flaps. The sockets were randomly assigned to the test group (thin gingiva) (TG), the test group with grafting material TG + GM, the control group (normal gingiva) (CG), or the control group with grafting material CG + GM. Ground sections were prepared from 12-week healing biopsies, and histomorphometry and fluorescence analysis were performed.In the groups with thin gingiva, numerically greater buccal bone loss was observed, while there were no differences between grafted and nongrafted sites. A numerically higher rate of mineralization was observed for the grafted sites, as compared with the nongrafted sites, at 12 weeks.A thin buccal bone plate leads to higher bone loss in extraction sockets, even with flapless surgery. The gingival thickness or the use of a graft material did not prevent buccal bone resorption in a naturally thin biotype, but modified the mineralization process.

To follow up the variations of early morning concentrations of oral volatile sulfur compounds (VSCs) in periodontally healthy subjects who refrained from toothbrushing during a period of 5 days while continuing with other hygiene procedures.Thirteen subjects volunteered for this study. At baseline, all subjects stopped brushing their teeth for 5 days, but continued using dental floss and a tongue scraper twice daily. Organoleptic measurements, VSC quantification and plaque index were recorded in all subjects at baseline and on days 3 and 5 of the study period.At baseline, the visible plaque index was significantly lower than that observed on days 3 and 5 (P = 0.0001). However, no significant differences in the amount of plaque were observed between days 3 and 5 (P0.05). The results of the organoleptic measurements and VSC quantifications did not show any statistically significant differences between baseline and day 3, or between days 3 and 5 (P0.05). However, a significant increase was observed in both VSCs (P = 0.008) and organoleptic scores (P = 0.032) when baseline values were compared to day 5. A positive correlation between VSCs and organoleptic scores was observed in all measurements (r = 0.67, P0.0001).The results of this study suggest that the lack of toothbrushing may affect VSC levels and the organoleptic perception of oral malodour due to the development of biofilm on buccal and lingual surfaces of teeth in healthy subjects.

Aim This randomized, controlled, clinical study compared two surgical techniques for root coverage with the acellular dermal matrix graft (ADMG) to evaluate which procedure could provide better root coverage and greater amounts of keratinized tissue. Materials and methods Fifteen pairs of bilateral Miller Class I or II gingival recessions were treated and assigned randomly to the test group, and the contra-lateral recessions were assigned to the control group. The ADMG was used in both groups. In the control group, the graft and flap were positioned at the level of the cemento-enamel junction (CEJ), and in the test group, the graft was positioned 1 mm apical to the CEJ and the flap 1 mm coronal to the CEJ. The clinical parameters were taken before the surgeries and after 6 months. The gingival recession area, a new parameter, was measured in standardized photographs through a special device and software. Results There were statistically significant differences favouring the proposed technique for all parameters except for the amount of keratinized tissue at 6 months. Conclusions The proposed test technique is more suitable for root coverage procedures with ADMG, and the new parameter evaluated appears valuable for root coverage analysis.

Smokers have small root coverage which is associated with bad vascularity of periodontal tissues. This study evaluated a technique that can increase the blood supply to the periodontal tissues compared with a traditional technique. Twenty heavy smokers (10 males and 10 females) with two bilateral Miller class I gingival recessions received coronally positioned flaps in one side (Control group)and extended flap technique in the other side (Test group). Clinical measurements (probing pocket depth, clinical attachment level, bleeding on probing, gingival recession height, gingival recession width, amount of keratinized tissue, and width and height of the papillae adjacent to the recession) were determined at baseline, 3 and 6 months postoperatively. Salivary cotinina samples were taken as an indicator of the nicotine exposure level. No statistically significant differences (p>0.05) were detected for the clinical measurements or smoke exposure. Both techniques promoted low root coverage (Control group: 43.18% and Test group: 44.52%). In conclusion, no difference was found in root coverage between the techniques. Root coverage is possible and uneventful even, if rather low, in heavy smoker patients with low plaque and bleeding indices.

The aim of this study is to compare the macro- and microsurgery techniques for root coverage using a coronally positioned flap (CPF) associated with enamel matrix derivative (EMD).Thirty patients were selected for the treatment of localized gingival recessions (GRs) using CPF associated to EMD. Fifteen patients were randomly assigned to the test group (TG), and 15 patients were randomly assigned to the control group (CG). The microsurgical approach was performed in the TG, and the conventional macrosurgical technique was performed in the CG. The clinical parameters evaluated before surgery and after 6 months were GR, probing depth, relative clinical attachment level, width of keratinized tissue (WKT), and thickness of keratinized tissue (TKT). The discomfort evaluation was performed 1 week postoperative.There were no statistically significant differences between groups for all parameters at baseline. At 6 months, there was no statistically significant difference between the techniques in achieving root coverage. The percentage of root coverage was 92% and 83% for TG and CG, respectively. After 6 months, there was a statistically significant increase of WKT and TKT in TG only. Both procedures were well tolerated by all patients.The macro- and microsurgery techniques provided a statistically significant reduction in GR height. After 6 months, there was no statistically significant difference between the techniques regarding root coverage, and the microsurgical technique demonstrated a statistically significant increase in WKT and TKT.

- Abstract
A prestação do serviço de Odontologia dentro do ambiente hospitalar teve início devido aos benefícios observados com o trabalho de equipes multidisciplinares no cuidado com a saúde. De modo geral, os pacientes são atendidos pelos cirurgiõesdentistas dentro dos hospitais terciários porque sua condição de saúde impede a realização dos procedimentos em consultórios ou unidades de saúde, devido, entre outros, à dificuldade de locomoção ou falta de equipe treinada para atender portadores de enfermidades sistêmicas. Estudos que enfocam esse tema têm observado benefícios importantes na condição de saúde do paciente. Dessa forma, o presente trabalho teve como objetivos: Caracterizar o Serviço de Odontologia Hospitalar no Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto - USP, nos seguintes aspectos: 1) assistencial: relacionar as atividades quanto ao número de atendimentos por tipo, procedência do paciente (internado ou ambulatorial), patologias de base e enfermaria específica; 2) financeiro: identificar a receita SUS dos procedimentos odontológicos realizados e identificar os custos do Serviço de Odontologia Hospitalar, e 3) percepção dos profissionais cirurgiõesdentistas e Chefes das especialidades médicas usuárias dos serviços de odontologia hospitalar, quanto aos serviços prestados, e a satisfação dos usuários pacientes. Foi realizada uma pesquisa exploratória descritiva com dados relativos ao ano de 2016, através de um estudo de caso. Para identificar a percepção dos profissionais e satisfação dos pacientes com os serviços odontológicos prestados pelo Hospital foram aplicados (em 2017) questionários específicos. Os resultados demonstraram prevalência de atendimentos ambulatoriais, sendo que os principais procedimentos realizados foram tratamentos periodontais, cirurgias e laserterapia. Quanto ao aspecto financeiro, observou-se que nem todos os procedimentos são reembolsados pelo SUS e seus custos ultrapassam o valor recebido. A receita media SUS e o custo por atendimentos foram R$ 59,91 e R$ 5,36 respectivamente. O estudo permitiu também concluir que a percepção / satisfação nas três esferas analisadas é positiva em relação do serviço prestado. Espera-se que as informações encontradas forneçam subsídios para a melhoria contínua do serviço existente dentro do hospital, bem como para outros gestores que desejam implantar a Odontologia Hospitalar em outros centros de referência. The provision of Dentistry service within the hospital environment began due to the benefits observed with multidisciplinary healthcare providers working together. In general, patients are attended by dentists at tertiary referral hospitals because their health condition which prevents the procedures to be performed in the clinic or health units, due, among others, to the difficulty of locomotion or lack of trained personnel to attend patients with systemic diseases. Studies that focus on this theme have observed important benefits in patient\'s health condition. Thus, the present study aimed to characterize the activities and procedures performed by the team of dental surgeons at Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto - USP in 2016 under the following aspects: 1) assistential: to relate the activities regarding the number of attendances according to the patient origin (ambulatory or nursery) and base pathology; 2) financial: identify the oral care procedures SUS revenues obtained and the costs incurred providing the service, and 3) stakeholders perception / satisfaction: evaluate the perception / satisfaction regarding the contribution of the service in the three mains spheres that comprise it: the dentists who provides care, the physician who works together with the dentistry staff and the patient. To meet these objectives, the descriptive exploratory research was chosen through case reports. To measure the perception / satisfaction specific questionnaires were applied for each group in 2017. The results demonstrated the prevalence of ambulatory care and the main procedures performed were periodontal treatments, surgeries and laser therapy. As for the financial aspect, it was observed that the service is deficient, since not all procedures are reimbursed by SUS and the costs exceed the amount received. In average, SUS reimbursed R$5,36 per procedure while the calculated costs were R$ 59,91. The study also concluded that the perception / satisfaction in the three spheres analyzed are positive in relation to the service provided. It is expected the results obtained will provide subsidies for the continuous improvement of the existing service within the hospital, as well for other managers who wish to implement Oral Service Medicine in other referral hospitals.
