Evaluation of characteristics of periodontal probes

Aim: This study aimed to evaluate the millimeter distances and active tip diameters of different periodontal probes. Methods: Two types of periodontal probes were analyzed (North Carolina (15-UNC) and PCP-12). Two manufacturers were selected for each probe type. Digital images of the probes were obtained and the distances were measured using a software program. The diameter of the active tip was measured using a digital caliper. Both variables were measured by two trained and calibrated examiners. The data were analyzed using the Bland-Altman method and two-way ANOVA with Tukey's post-hoc test. Statistical significance was set at p<0.05. Results: A comparison of measurements between the 15UNC and PCP-12 probes showed a significant difference in all millimeter markings. The 15-UNC probe showed differences between the 3 and 12 mm markings. The PCP-12 probe only showed differences between the marks at the 12 mm mark. The 15-UNC probe had a similar active tip diameter between the two manufacturers. The PCP-12 probe showed a significant difference between the two manufacturers. Both types of probes had similar active tip diameters when compared by the two manufacturers. Conclusion: There was no standardization in relation to millimeter marks and tip diameters of the two types of periodontal probes produced by the two different manufacturers. The probe types exhibited little variability

Antibiotics prescribing habits of Brazilian general dental practitioners during periodontal treatments / Hábitos de prescrição de antibióticos de dentistas brasileiros durante tratamentos periodontais

Introdução: O tratamento periodontal envolve procedimentos que visam reduzir a carga bacteriana, envolvendo ou não o uso de antibióticos locais ou sistêmicos. Objetivo: O objetivo deste estudo foi avaliar o conhecimento dos cirurgiões-dentistas brasileiros sobre a prescrição de antibióticos durante o tratamento periodontal. Material e método: Foi disponibilizado um questionário online solicitando aplicação sistêmica de prescrição de antibióticos locais ou sistêmicos (frequência e sequência com tratamento periodontal mecânico) e em relação a diferentes doenças periodontais. A utilização de serviços de diagnóstico microbiano e dados demográficos dos voluntários também foram elucidados. Os dados foram analisados estatisticamente (Teste Binomial, p<0,05). Resultado: Trezentos e noventa e três voluntários responderam ao questionário. Vinte e três por cento do sexo masculino e 76,2% do sexo feminino. A idade média foi de 27,7 anos. A minoria (19,2%) dos voluntários relatou indicar antibióticos sistêmicos para tratamento de gengivite ou periodontite estágios I e II (antiga periodontite crônica leve e moderada). A maioria dos profissionais indica para tratar abscesso periodontal, gengivite ou periodontite ulcerativa necrosante, periodontite em imunodeficiências graves, periodontite agressiva antiga e periodontite estágios III e IV (periodontite crônica grave antiga). Raramente (2,5%) a prescrição foi sem a associação com terapia mecânica. Os exames microbiológicos como método auxiliar de diagnóstico raramente (3,1%) são solicitados por falta de informação ou custo. As respostas mais frequentes sobre o número de vezes que os profissionais relataram prescrever antibióticos sistêmicos como parte do tratamento periodontal por trimestre foram "pelo menos uma vez", seguido de "2 vezes". Conclusão: Pode-se concluir que os cirurgiões-dentistas brasileiros possuem conhecimento sobre a correta prescrição de antibióticos na terapia periodontal

Introduction: Periodontal treatment involves procedures aimed to reduce bacterial load, involving or not the use of local or systemic antibiotics. Objective: The purpose of this study was to assess Brazilian dentists' knowledge about antibiotics prescription during periodontal treatment. Material and method: An online questionnaire was available asking for systemic application of local or systemic antibiotics prescription (frequency, and sequence with mechanical periodontal treatment) and in relation to different periodontal diseases. The use of microbial diagnostic services and volunteers' demographic data were also elucidated. Data were statistically analyzed (Binomial Test, p<0.05). Result: Three hundred and ninety-three volunteers answered the questionnaire. Twenty-three percent males and 76.2% females. Average age was 27.7 years. Minority (19.2%) of the volunteers reported to indicate systemic antibiotics to treat gingivitis or periodontitis stages I and II (old slight and moderate chronic periodontitis). Majority of the professionals indicate it to treat periodontal abscess, necrotizing ulcerative gingivitis or periodontitis, periodontitis in severe immunodeficiencies, old aggressive periodontitis, and periodontitis stages III and IV (old severe chronic periodontitis). Rarely (2.5%) the prescription was without the combination with mechanical therapy. Microbiological tests as an auxiliary diagnostic method are rarely (3.1%) requested due to lack of information or cost. Most frequent answers about the number of times professionals reported prescribing systemic antibiotics as part of periodontal treatment per trimester was "at least once", followed by "2 times". Conclusion: It can be concluded that Brazilian dentists have knowledge about the correct prescription of antibiotics in periodontal therapy

Impact of the COVID-19 pandemic on publication rate in periodontology and implantology in Turkey / Impacto da pandemia de COVID-19 na taxa de publicação em periodontia e implantodontia na Turquia

Objective: The aim of the present study was to evaluate the impact of the COVID-19 pandemic on the number of publications in the field of periodontology and implantology in Turkey. Material and Methods: A sensitive search strategy was developed to identify relevant articles, focusing on the periodontology and implantology research fields published two years before and after the declaration of the pandemic (March 2020). The search was performed through Web of Science, Medline, SCOPUS and CENTRAL databases. A three-stage screening (titles, abstract, full-text) was carried out in duplicate and independently by two reviewers. Results: A total of 382 studies were identified before the pandemic and 307 studies during the pandemic. While there was a downward trend in the number of observational studies (185 vs 168), the number of clinical trials (CCT/RCT) slightly increased compared to the pre-pandemic period (72 vs 74). Conclusion: Limited to the selected period of time (two years) and field, publication rate on periodontology and implantology in Turkey was decreased during the pandemic. Although the present research highlights current trends, large-scale investigations are needed to probe consequences of COVID-19 pandemic on research activities in the long-run (AU).

Material e Métodos:Foi desenvolvida uma estratégia de busca sensível para identificar artigos relevantes, com foco nas áreas de pesquisa em periodontia e implantodontia publicados dois anos antes e depois da declaração da pandemia (março de 2020). A busca foi realizada nas bases de dados Web of Science, Medline, SCOPUS e CENTRAL. Uma triagem de três etapas (títulos, resumo, texto completo) foi realizada em duplicata e de forma independente por dois revisores. Resultados: Foram identificados 382 estudos antes da pandemia e 307 estudos durante a pandemia. Embora tenha havido uma tendência de queda no número de estudos observacionais (185 vs 168), o número de ensaios clínicos (CCT/RCT) aumentou ligeiramente em comparação com o período pré-pandêmico (72 vs 74). Conclusão: Limitada ao período de tempo selecionado (dois anos) e área, a taxa de publicação em periodontia e implantodontia na Turquia diminuiu durante a pandemia. Embora a presente pesquisa destaque as tendências atuais, são necessárias investigações em larga escala para investigar as consequências da pandemia de COVID-19 nas atividades de pesquisa a longo prazo.(AU)

Management of unerupted anterior teeth an audit of treatment outcomes

Anterior teeth are valuable for aesthetics, speech and mastication . Their absence, impaction and/or delayed eruption create significant distress often leading to early presentation to the dental office. This study presents an audit of the management of impacted anterior teeth that presented at a tertiary level dental clinic. The periodontal outcomes of the aligned teeth were also reported. Methods : This is an observational study spanning a nine-year period. Demographic data, clinical presentation as well as post alignment dental and periodontal status of the impacted teeth were assessed. Data was analysed using the Statistical Package for Social Sciences (SPSS) version 26. Fisher's exact test and paired samples T-test were used for categorical and continuous variables respectively. Significance was set at P < 0.05. Results: Twenty-eight (1.76%) cases presenting with failed eruption of thirty-two anterior teeth were found during the period under review. Eight patients were treated by extraction, orthodontic treatment and space closure or prosthetic replacement with a mean treatment time of 2.83 ± 2.66 years. Thirteen patients completed treatment by orthodontic alignment with mean alignment time of 1.4 ± 1.5 years and treatment time of 3.6 ± 2.5 years. There was significant difference in the post-operative root length of aligned teeth compared to their normal antimeres (p < 0.005). Conclusion: Patients with impacted anterior teeth presented later than was beneficial for spontaneous alignment of their teeth. The average 1.5mm loss of root length observed was not detrimental to the anatomical retention or function of the aligned teeth. There is need for more enlightenment with regards to early presentation for dental problems to avoid expensive and time-consuming treatments.

Factores etiológicos de abscesos periodontales: Una patología emergente. Informe de tres casos / Etiological factors of periodontal abscesses: an emerging pathology. A three-case report

Introducción: La presencia de abscesos periodontales es la tercera emergencia dental más frecuente (6%-14%). Objetivo: Reportar información sobre diferentes factores etiológicos de absceso periodontal en tres pacientes. Descripción de casos: Primer caso, mujer de 52 años quien acudió a consulta por sangrado espontáneo, al examen clínico se evidenció sangrado al sondaje (SS), presencia de bolsas periodontales (BP) y cálculos (C); como tratamiento se realizó raspado y alisado radicular (RAR), complementado con detoxificación con tetraciclina y tratamiento farmacológico posoperatorio. Segundo caso, hombre de 27 años quien acudió a consulta por agrandamiento de encía, se observó (SS), y (BP); se retiró la lesión y se realizó (RAR). Tercer caso, hombre de 21 años quien acudió a consulta de control, al examen clínico se evidenció presencia de cálculos en órganos dentarios y bolsas periodontales en órganos dentarios 16-17; se utilizó (RAR) complementado con detoxificación con tetraciclina y tratamiento farmacológico posoperatorio. Conclusión: La etiología del absceso periodontal en el primer y último caso se basó en la falta de profundidad durante el raspado y alisado radicular, y en el segundo estuvo relacionado a impactación de alimentos. El identificar la etiología permite determinar diagnóstico, pronóstico y tratamiento ideal.

Introduction: Periodontal abscesses are the third most frequent dental emergency (6%-14%). Objective: To describe different etiological factors of periodontal abscesses in three patients. Case description: The first case was a 52-year-old woman who sought treatment due to spontaneous bleeding. During the examination, she revealed bleeding on probing (BP), presence of periodontal pockets (PP), and calculi (C). Scaling and root planning (SRP) was performed as treatment, which was complemented with detoxification with tetracycline and postoperative pharmacological treatment. The second case was a 27-year-old man who came to the clinic due to gum enlargement and showed BP and PP. The lesion was treated and SRP was performed. Finally, the third patient was a 21-year-old male who sought a follow-up consultation. The clinical examination showed the presence of dental calculi and periodontal pockets in teeth 16 and 17. SRP complemented with detoxification with tetracycline and postoperative pharmacology were used as treatments. Conclusion: The etiology of the periodontal abscesses in the first and third cases was based on the lack of depth during root scaling and planning. The cause in the second case was effects of food. Identifying this etiology is useful to achieve proper diagnosis, prognosis and treatment of periodontal abscesses.

Patient experience and non-surgical periodontal therapy in a postgraduate periodontal training program: A qualitative study

ABSTRACT: Objective: To explore patient experience for non-surgical periodontal therapy using phenomenography. Methods: This qualitative study was performed in a postgraduate specialist training program in periodontics. Patients reported their experiences through in-depth interviews in order to recognize the impact of non-surgical periodontal therapy on their quality of life and their satisfaction. A homogeneous sampling procedure was used, establishing redundancy after the fifteenth interview. Interviews were audio recorded, transcribed and analyzed by three researchers who codified the answers into categories to determine the emerging topics. Results: The core emerging themes were: (i) lack of information about periodontal disease; (ii) experience during treatment; (iii) treatment implications; and (iv) clinician-patient relationship. Conclusions: Patients seem to have limited knowledge about periodontal diseases. Reasons for attendance mainly include bleeding gums, tooth mobility, and aesthetic problems. Therapy can generate pain, fear, and is considered invasive, whereas dentine hypersensitivity may occur post-operatively. Despite this, patients would be willing to undergo treatment again and were generally satisfied with the level of care and treatment received.

Prevention of oral cancer through the implementation of a teledentistry platform for the elderly / Prevención del cáncer oral mediante la implementación de una plataforma de teleodontología para adultos mayores

Objective: To contribute to early diagnosis of lesions in older patients, including potentially malignant lesions or those suspected of oral cancer by support of a web-based teledentistry platform. Material and Methods:This report contains information from 27 patients with oral lesions out of a total of 135 who received mobile dental care. Specialists who participated in the study involved professionals from the disciplines of periodontics, temporomandibular disorders, oral implantology, oral radiology, oral pathology and geriatrics. Referral consultations were carried out synchronously or asynchronously. Clinical information sent to oral pathology specialists involved a medical history and a traditional description of the lesion which considered size, color, limits, symptomatology, type of surface, consistency, location, and evolution. This information was complemented with a three-dimensional representation of the lesion, simulating an extra/intra oral clinical examination including a marker tool that allows to perform the anatomical-referencing of oral lesions. Results:27 consultations from 26 patients were evaluated for oral pathology lesions. 12 lesions were diagnosed as reactive, 5 were infectious lesions, 4 of vascular etiology, 3 pigmented lesions (amalgam tattoo and smoking-related melanosis) and 3 potentially malignant lesions. The most frequent location was the tongue with 8 cases, followed by the gingiva and jugal mucosa, each with 5 cases. Four lesions required biopsy and histopathological report. Conclusion: A teledentistry platform including digital representations of oral lesions using different digital markers, also associated with a mobile system to provide dental care, constitutes an excellent tool to treat patients that present oral lesions with potential cancer risk.

Objetivo: Contribuir al diagnóstico precoz de lesiones en pacientes mayores, incluyendo lesiones potencialmente malignas o con sospecha de cáncer oral mediante el apoyo de una plataforma de teleodontología basada en la web.Material y Métodos: Este informe contiene información de 27 pacientes con lesiones orales de un total de 135 que recibieron atención odontológica móvil. Los especialistas que participaron en el estudio incluyeron profesionales de las disciplinas de periodoncia, trastornos temporomandibulares, implantología oral, radiología oral, patología oral y geriatría. Las interconsultas se realizaron de forma sincrónica o asincrónica. La información clínica enviada a los especialistas en patología oral involucró una historia clínica y una descripción tradicional de la lesión que consideró tamaño, color, límites, sintomatología, tipo de superficie, consistencia, localización y evolución. Esta información se complementó con una representación tridimensional de la lesión, simu-lando un examen clínico extra/intraoral incluyendo una herramienta marcadora que permite realizar la referenciación anatómica de las lesiones orales. Resultados: Se evaluaron 27 consultas de 26 pacientes por lesiones de patología bucal. Se diagnosticaron 12 lesiones como reactivas, 5 lesiones infecciosas, 4 de etiología vascular, 3 lesiones pigmentadas (tatuaje de amalgama y melanosis por tabaquismo) y 3 lesiones potencialmente malignas. La localización más frecuente fue lengua con 8 casos, seguida de encía y mucosa yugal con 5 casos cada una. Cuatro lesiones requirieron biopsia e informe histopatológico. Conclusión: Una plataforma de teleodontología que incluye representaciones digitales de lesiones orales utilizando diferentes marcadores digitales, también asociada a un sistema móvil para brindar atención odontológica, constituye una excelente herramienta para tratar pacientes que presentan lesiones orales con riesgo potencial de cáncer.

Levantamento metodológico de revisões sistemáticas de estudos de intervenção em periodontia utilizando AMSTAR 2 e ROBIS / Methodological survey of systematic reviews of intervention studies in periodontology using AMSTAR 2 and ROBIS

Este estudo teve o objetivo de avaliar a qualidade metodológica e risco de viés das revisões sistemáticas e metanálises de estudos de intervenção (randomizados e não randomizados) na área de Periodontia. Buscas foram realizadas nas bases de dados: MedLine (PubMed), Embase (Elsevier), Web of Science, Scopus, Cochrane Library e LILACS para artigos de revisão sistemática, com ou sem metanálise, indexados no ano 2019 a 2020. Adicionalmente, foram realizadas buscas na literatura cinzenta, nas referências dos artigos selecionados e nos principais periódicos de área. As avaliações da qualidade metodológica e risco de viés foram realizadas através das ferramentas AMSTAR 2 e ROBIS, respectivamente. Os dados foram importados para o software IBM SPSS Statistics for Windows versão 25. Análises descritivas de frequência relativa e absoluta foram realizadas nas variáveis categóricas. Análises descritivas de média, desvio padrão e mínima/máxima foram realizadas nas variáveis contínuas. Cento e vinte e sete revisões sistemáticas cumpriram os critérios de elegibilidade e foram avaliadas. Na avaliação geral pelo ROBIS, 113 (90,6%) das revisões apresentaram alto risco de viés, 11 (7,1%) baixo risco de viés e 3 (2,4%) risco de viés indefinido. Segundo o AMSTAR 2, a qualidade metodológica foi alta em 13 revisões (10,2%), moderada em 1 (0,8%), baixa em 31 (24,4%) e criticamente baixa em 82 (64,6%). No geral, a qualidade das revisões sistemáticas de estudos de intervenção na área de Periodontia foi considerada baixa. Sugere-se que os pesquisadores que pretendam realizar revisões sistemáticas utilizem ao menos um dos dois instrumentos no processo de desenvolvimento do protocolo da revisão. Este simples processo, se respeitado e seguido em conjunto o PRISMA, tem o potencial de resultar na criação de protocolos mais completos e, consequentemente, em revisões de melhor qualidade.

This study aimed to assess the methodological quality and risk of bias of systematic reviews and meta-analyses of intervention studies (randomized and nonrandomized studies) in periodontics. The following databases were searched: MedLine (PubMed), Embase (Elsevier), Web of Science, Scopus, Cochrane Library, and LILACS for systematic review articles, with or without meta-analysis, indexed between 2019 to 2020. Additionally, we searched on grey literature, and a manually searched the references of selected articles and main journals in the area. AMSTAR 2 and ROBIS tools were used to assess the methodological quality and risk of bias, respectively. Data were imported into the IBM SPSS Statistics for Windows version 25 software. Categorical variables were descriptively analyzed by relative and absolute frequency. Continuous variables were analyzed by mean, standard deviation, and minimum/maximum. One-hundred twenty-seven systematic reviews were included and were evaluated. In the overall ROBIS assessment, 113 (90.6%) were at high risk of bias, 11 (7.1%) were at low risk of bias, and 3 (2.4%) had unclear risk of bias. According to AMSTAR 2, 13 reviews (10.2%) had high methodological quality, 1 (0.8%) moderate, 31 (24.4%) low and 82 (64.6%) critically low. Overall, the quality of systematic reviews of intervention studies in the field of periodontics was low. Systematic review authors could use at least one between both tools before creating the study protocol. This simple process, if followed together with PRISMA, has the potential aid authors in the creation of more complete protocols and, consequently, better quality reviews.

Influence of proximal contact point on alveolar bone crest in teeth moved to extraction sites: pilot study / Influência do ponto de contato proximal na crista óssea alveolar em dentes movidos pala locais de extrações dentárias: um estudo piloto

Introduction: The opening of the contact point can happen after orthodontic closure of the site of dental extraction and opened interproximal contacts are considered potential factors for periodontal diseases. Objective: To evaluate the condition of the alveolar bone crest of the interdental site between canines and upper premolars with or without contact points in individuals submitted to orthodontics associated with the extraction of the first premolars. Material and Methods: This cross-sectional observational study selected upper canines and premolars of individuals undergoing orthodontic treatment without extractions (12 hemiarches ­ control group), or with extraction of the upper first premolars and whose canines and second premolars had interproximal contact (11 hemiarches ­ group 1) or diastema (15 hemiarches ­ group 2). The height and the presence of lamina dura in the interproximal bone crest of the distal surfaces of canines and mesial surfaces of premolars were evaluated. Results: Groups 1 and 2 demonstrated the higher and smallest prevailing of the presence of lamina dura, respectively. The control group presented the bone crest positioned more crownly in relation to the others groups. Experimental groups did not present significant differences to the height of bone crest. Conclusion: The orthodontic allocation of teeth to extraction sites was associated with the significant reduction of the height of the marginal bone crest, regardless of the presence or absence of contact point between the teeth. The lack of contact point resulted in a minor prevalence of the continuity of the lamina dura of the alveolar bone crest in these regions.

Introdução: A abertura do ponto de contato pode ocorrer após o fechamento ortodôntico do sítio de extração dentária e os contatos interproximais abertos são considerados fatores potenciais para as doenças periodontais. Objetivo: Avaliar a condição da crista óssea alveolar do espaço interdentário entre caninos e pré-molares superiores com ou sem pontos de contato em indivíduos submetidos a tratamento ortodôntico associado à exodontia dos primeiros pré-molares. Material e Métodos: Este estudo transversal observacional selecionou caninos e pré-molares superiores de indivíduos submetidos a tratamento ortodôntico sem extrações (12 hemiarcos ­ grupo controle), ou com exodontia dos primeiros pré-molares superiores e cujos caninos e segundos pré-molares tiveram contato interproximal (11 hemiarcos ­ grupo 1) ou diastemas (15 hemiarcos ­ grupo 2). Foram avaliadas a altura e a presença da lâmina dura na crista óssea interproximal das superfícies distais dos caninos e mesiais dos pré-molares. Resultados: Os grupos 1 e 2 demonstraram a maior e a menor prevalência da presença de lâmina dura, respectivamente. O grupo controle apresentou a crista óssea posicionada mais coronalmente em relação aos demais grupos. Entre os grupos experimentais, não houve diferença significativa para a altura da crista óssea. Conclusão: Neste estudo preliminar, a movimentação ortodôntica dos dentes para os locais de exodontia foi associada à redução significativa da altura da crista óssea marginal, independentemente da presença ou ausência de ponto de contato entre os dentes. A falta de ponto de contato resultou em menor prevalência de continuidade da lâmina dura da crista óssea alveolar nessas regiões.

Efficacy of combined application of glycine powder air-polishing in non-surgical treatment of peri-implant diseases / 北京大学学报(医学版)

OBJECTIVE@#To compare the clinical efficacy of combined application of glycine powder air-polishing and mechanical submucosal debridement in non-surgical treatment of peri-implant diseases.@*METHODS@#A randomized controlled clinical study was carried out on patients diagnosed with peri-implant diseases in the Department of Periodontology, Peking University School and Hospital of Stomatology, between May of 2020 and June of 2021.Twenty-eight patients with totally sixty-two implants were enrolled.The patients were randomly divided into the test group and control group. The patients in the test group (13 subjects/32 implants) received mechanical submucosal debridement using titanium curettes combined with application of glycine powder air-polishing, while the control group (15 subjects/30 implants) received mechanical submucosal debridement using titanium only. Clinical parameters, such as plaque index (PLI), pocket probing depth (PPD), bleeding index (BI) and the percentage of suppuration on probing on implants' level (SoP%) were measured at baseline and 8 weeks after non-surgical intervention. Changes and group differences of clinical parameters of the implants before and 8 weeks after non-surgical intervention were compared.@*RESULTS@#Mean PLI, PPD, BI of both the test group and control group significantly reduced 8 weeks after non-surgical intervention (P < 0.05). Compared with the control group, the test group achieved lower BI (2.7±0.8 vs. 2.2±0.7, P < 0.05), more reduction of BI (0.6±0.7 vs. 1.1±0.6, P < 0.01) and more reduction of SoP% (21.9% vs. 10%, P < 0.05) after non-surgical intervention. Both the control and test groups exhibited comparable PLI and PPD reductions (P>0.05). For the implants diagnosed with peri-implant mucositis, the test group revealed more signi-ficant reduction in BI and SoP% than the control group (1.0±0.7 vs. 0.4±0.7, P=0.02; 6.3% vs. 0, P=0.012). There was no significant difference existing in PLI and PD improvement between the control group and test group (P>0.05). For the implants diagnosed with peri-implantitis, there was no significant difference existing in PLI, PPD, BI and SoP% improvement values between the test and control groups (P>0.05). No complications or discomforts were reported during the study.@*CONCLUSION@#Both treatment procedures could relieve the inflammation of peri-implant soft tissue. Non-surgical mechanical submucosal debridement combined application of glycine powder air-polishing is associated with significant reduction of soft tissue bleeding and suppuration on probing especially in the implants diagnosed with peri-implant mucositis.

ABSTRACT: In patients with periodontitis, pathologic tooth migration is a consequence of loss of periodontal support. The following case report addresses the periodontal and orthodontic treatment of a patient with periodontitis and pathologic tooth migration. The protocol used was the protocol of the Orthodontics and Periodontics Unit of the Faculty of Dentistry of the University of Chile. The periodontal stability has been maintained for at least 6 years after the end of orthodontic treatment, achieving functionality and aesthetics of the natural dentition.

Desarrollo de la periodontología en Santiago de Cuba / Development of periodontology in Santiago de Cuba

Se realizó una investigación de carácter histórico con el fin de exponer brevemente el desarrollo de la periodontología en Santiago de Cuba desde 1974 hasta la actualidad. Esta especialidad se ha venido fomentando de forma paulatina y hoy día cuenta con profesionales preparados integralmente para brindar una atención estomatológica especializada de calidad; también se vincula a la actividad docente-asistencial, con un claustro de 14 profesores altamente calificados. Puede afirmarse, entonces, que la formación del capital humano se ha cumplimentado por años -de acuerdo a la demanda poblacional y a los requerimientos del Sistema Nacional de Salud-, pues se ha contribuido, en gran medida, al perfeccionamiento y la preparación de estos especialistas con vistas a preservar, durante el presente y en el futuro, la salud periodontal de la población santiaguera.

An investigation of historical character aimed at briefly exposing the development of periodontology was carried out in Santiago de Cuba from 1974 to the present time.

It can be affirmed then, that the human capital training has been fulfilled per years -according to the populational demand and the requirements of the National Health System-, because it has been contributed, in such an extent, to the improvement and preparation of these specialists aiming at preserving, during present and future times, the periodontal health of people from Santiago de Cuba.

Clinical Management of Intra-Pulp Canal Broken Endodontic Files in Primary Teeth: Literature Review / Manejo clínico de las limas endodónticas fracturadas dentro del conducto pulpar en dientes primarios: Revisión de la literatura

ABSTRACT: Fracture of an endodontic file inside a primary root canal is a rare but critical complication during the pulpectomy treatment, because the mechanical obstruction impedes the optimal cleaning and obturation of the pulp canal, compromising seriously the clinical outcome. This accidental event is mainly associated with over-use and excessive torque of intracanal files. Most clinicians opt to proceed with the extraction of the affected tooth followed by a space maintainer placement. Other practitioners attempt the non-surgical retrieval of the separated fragment through available proven techniques in permanent teeth; however, these methods may involve significant damage to the tooth and surround tissues. On the other hand, preservation of the metallic fragment might affect the treatment prognosis and interfere with the physiological root resorption.

RESUMEN: La fractura de una lima endodóntica dentro de un conducto radicular primario es una complicación rara aunque critica durante el tratamiento de pulpectomía, debido a que la obstrucción mecánica impide la limpieza y obturación óptimas del conducto pulpar, comprometiendo seriamente el resultado clínico. Este evento accidental está principalmente asociado con el sobreuso y torque excesivo de las limas dentro del conducto. La mayoría de los clínicos optan por realizar la extracción del diente afectado, seguido por la colocación de un mantenedor de espacio. Otros practicantes intentan la remoción no quirúrgica del fragmento separado a través de técnicas disponibles probadas en dientes permanentes; sin embargo, estos métodos pueden causar daños significativos al diente y tejidos circundantes. Por otra parte, la preservación del fragmento metálico puede afectar el pronóstico del tratamiento e interferir con el proceso de reabsorción radicular fisiológico.
