Comparison of the effectiveness of two manual toothbrushes: Conventional design versus double-sided toothbrush design. A pilot study.

OBJECTIVES: Dental hygiene is the most effective method in the prevention of oral diseases. However, most patients do not use the recommended teeth brushing techniques and/or time brushing is insufficient. With this objective, modifications in conventional toothbrushes have been developed to deal with these findings. The aim of this study was to compare plaque removal effectiveness of a manual toothbrush with a modified head (MTMH) with a wrap-around design versus a conventional manual toothbrush. METHODS: This pilot prospective clinical study was designed according to STROBE guidelines. The patients suspended oral hygiene habits for 24 h (baseline). Subsequently, the teeth were brushed for 60 s. Both toothbrushes followed the same study procedure, separated by 1 month. Plaque-removing effectiveness was measured before and after tooth brushing using the modified O'Leary Plaque Index (PI). RESULTS: Seven patients were included in this pilot study. The mean age was 37.66 ± 10.68 years. PI mean differences between baseline and after brushing were 51.99% ± 16.43 for MTMH and 27.93 ± 6.85, for conventional toothbrush (p = 0.0013). After brushing, mean PI values were 18.36% ± 6.95%, and 37.61% ± 10.57% respectively (p < 0.001). CONCLUSION: Within the limitations of the present study, it can be concluded that the effectiveness of plaque removal by using MTMH is significantly higher than the conventional manual toothbrush.

Patient-reported outcomes in patients with severe maxillary bone atrophy restored with zygomatic implant-supported complete dental prostheses: a systematic review.

Introduction and Objective: Zygomatic implants (ZI) offer a good and predictable alternative to reconstructive procedures of atrophic maxillae. The main objetive of this systematic review was to assess the effect of rehabilitation with zygomatic implants on patient's quality of life (QLP) using Patient Reported Outcomes Measures (PROMs).Materials and Methods: This review followed PRISMA guidelines. An automated electronic search was conducted in four databases supplemented by a manual search for relevant articles published until the end of January 2021. The Cochrane Collaboration Risk of Bias tool and the Newcastle-Ottawa Quality Assessment Scale were used to assess the quality of evidence in the studies reviewed.Results: General findings of this systematic review showed substantial increases in Oral health-related quality of life (OHRQoL) among patients restored with ZI and high scores in terms of general satisfaction, especially in chewing ability and esthetics. An overall survival rate of ZI was 98.3% after a mean follow-up time of 46.5 months was observed. Occurrence of 13.1% biological complications and 1.8% technical complications were reported.Conclusions: Patients rehabilitated with zygomatic implant-supported complete dental prostheses showed substantial improvements in OHRQoL and general satisfaction with the treatment received.

Complications associated with vertical bone augmentation techniques in implant dentistry: A systematic review of clinical studies published in the last ten years.

Vertical bone augmentation procedures are increasingly necessary in daily practice. However, it has been reported that vertical ridge augmentation is one of the least predictable techniques in terms of complications. The aim of this systematic review was to evaluate and compare complications in relation to the different procedures used for vertical bone augmentation prior to implant placement. This review was conducted according to PRISMA guidelines. An electronic search was carried out in four databases: The National Library of Medicine (MEDLINE/PubMed); Web of Science; SCOPUS; and Cochrane Central Register of Controlled Trials (CENTRAL). The Newcastle-Ottawa Quality Assessment Scale, the Cochrane Collaboration tool for assessing risk of bias, and The Joanna Briggs Institute Critical Appraisal tool were used to assess the quality of evidence in the studies reviewed. Twenty-five studies with a total of 749 vertically augmented sites were included in the review. Complication rates varied among the different procedures: 51.02% for distraction osteogenesis, 38.01% for bone blocks, and 16.80% for guided bone regeneration. Vertical bone augmentation procedures prior to implant placement are associated with frequent surgical complications and should be approached with caution due to their possible impact on clinical treatment success.

Effect of time-dependent ibuprofen administration on the post operatory after impacted third molar extraction: a cross-over randomized controlled trial.

PURPOSE: To evaluate time-dependent administration of ibuprofen in a lower third molar extraction model. METHODS: Eleven patients requiring bilateral surgical removal of lower third molars were recruited and randomized into a blinded crossover randomized controlled trial. For 3 days after surgery, the control group was prescribed ibuprofen 400 mg every 8 h. On the other hand, the experimental group received also ibuprofen 400 mg at breakfast and lunch, replacing the dinner intake with a placebo. Pain measurements (Visual Analog Scale from 0 to 10) were recorded at baseline, 24, 48, and 72 h postoperatively. Facial swelling and trismus were also measured at baseline, 24, and 72 h postoperatively. RESULTS: Postoperative swelling and pain perception did not show significative difference between the control and experimental groups at 24, 48, and 72 h. Trismus was significantly lower in the control group than in the experimental group at 72 h postoperatively (p = 0.008). Rescue medication consumption seemed to be comparable between groups. CONCLUSION: Eliminating night time ibuprofen might be insignificant for pain control after third molar extraction.

Autogenous particulated dentin for alveolar ridge preservation. A systematic review.

PURPOSE: This review aimed to investigate the clinical outcomes of autogenous particulated dentin (APD) used for alveolar ridge preservation (ARP), evaluating volume gain, histologic/histomorphometric data, and associated complications. MATERIAL AND METHODS: The review followed PRISMA guidelines and was registered in the International Prospective Register of Systematic Reviews (PROSPERO). An automated search was made in four databases (Medline/Pubmed, Scopus, Web of Science, and Cochrane Library) supplemented by a manual search for relevant clinical articles published before March 10th, 2022. The review included human studies of at least four patients in which extraction and subsequent ARP were performed in a single surgery. Both comparative studies and studies that assessed ARP with APD exclusively were admitted. The quality of evidence was assessed with the Cochrane bias assessment tool, the Newcastle-Ottawa Quality Assessment Scale, and the Joanna Briggs Institute Critical Appraisal tool. RESULTS: Eleven studies fulfilled the inclusion criteria and were included for descriptive analysis, with a total of 215 patients, and 337 alveoli preserved by APD, spontaneous healing (blood clot), or other bone substitutes, obtaining comparatively less vertical and horizontal resorption when APD was used. CONCLUSIONS: After dental extraction, autogenous dentin was effective in terms of volume maintenance, showing promising results in histologic/histomorphometric analysis, and a low complication rate. Nevertheless, few comparative studies with comparable parameters have been published and so more research providing long-term data is needed to confirm these findings.

Medium-term clinical behaviour of one-piece zirconia implants supporting single crowns or fixed dental prostheses: A systematic review and meta-analysis.

PURPOSE: This systematic review aimed to evaluate the medium-term (3-year) overall survival and success rates, marginal bone loss and different biological parameters displayed with one-piece zirconia implants. MATERIALS AND METHODS: Electronic searches were conducted of the MEDLINE (via PubMed), Scopus (Elsevier), Cochrane Library (Wiley) and Web of Science (Clarivate Analytics) databases and manual searching was also performed for relevant articles published up to 14 November 2022. The review included human studies with a minimum of 10 subjects and/or 20 implants and with a follow-up period of at least 3 years after implant placement. RESULTS: Twelve studies met the inclusion criteria and were included for analysis, giving a total of 1,621 one-piece zirconia implants. Eleven studies were included to perform a meta-analysis of survival rates, and six for success rates and marginal bone loss. The survival and success rates at the 3-year follow-up were 94.4% (95% confidence interval 90.4%-98.4%; P < 0.001) and 91.6% (95% confidence interval 84.2%-98.9%; P < 0.001), respectively, and marginal bone loss was 0.231 mm (95% confidence interval 0.190-0.272; P < 0.001). CONCLUSIONS: One-piece zirconia implants appear to be a reliable option for restoring missing teeth, obtaining an implant survival rate of 94.4% and a success rate of 91.6% after a follow-up period of at least 3 years. Moreover, the results showed acceptable rates of marginal bone loss and adequate biological parameters.

Brain complications from odontogenic infections: A systematic review.

PURPOSE: Odontogenic infections can spread through different routes to more remote anatomical areas, such as the brain. Brain abscesses have an incidence of 0.3-1.3 / 100,000 population and only 2-5% are of dental origin. The main objective is to research brain complications derived from odontogenic infections. Secondary objectives were to identify the most common symptoms in brain abscess, to describe the microbiology involved in these infectious processes, report which parts of the brain complex are most commonly affected and report the sequelae of this patients. METHODS: A systematic review following the PRISMA Guide and the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Case Reports was carried out in PubMed, Scopus and Web of Science. The search terms were: Brain infection, brain abscess, oral health oral origin, odont* infect*. RESULTS: The database search identified a total of 1000 articles. A total of 18 publications were identified after applying inclusion and exclusion criteria. A total of 38 patients were analyzed. Mean age was 49.64±18.80 years. CONCLUSION: The most common symptoms of patients with brain abscess are neurological affectations first and then fever and headache second, without necessarily presenting as a symptomatological triad. Microbiological diagnosis is key to determining the origin of the infection. Anaerobic pathogens such as Streptococcus (F. Milleri), Fusobacterium Nucleatum and Porfiromonas Gingivalis families are common bacterial agents. The frontal lobe is the most frequently affected, followed by the parietal and temporal lobe. The most frequent brain complications are neurological disorders. However, most patients with brain abscesses recover without sequelae.

Socket shield technique: A systematic review of human studies.

BACKGROUND AND PURPOSE: Alveolar bone resorption after dental extraction frequently leads to situations in which long-term function and esthetic success of rehabilitations with dental implants is a challenge. Socket shield has been described as an alternative technique to maintain the alveolar ridge when placing immediate implants. The aim of this review is to evaluate the medium- and long-term clinical outcomes of the socket shield technique in human studies. MATERIAL AND METHODS: This review was conducted according to PRISMA guidelines. An electronic search was conducted in four databases: (1) The National Library of Medicine (MEDLINE/PubMed) via Ovid; (2) Web of Science (WOS); (3) SCOPUS; and (4) Cochrane Central Register of Controlled Trials (CENTRAL). The Cochrane Collaboration tool, the Newcastle-Ottawa Quality Assessment Scale and The Joanna Briggs Institute Critical Appraisal tool were used to assess the quality of evidence in the studies reviewed. RESULTS: Six articles were included in this review. The studies analysed showed lower rates of horizontal and vertical alveolar bone resorption, better maintenance of the buccal plate, less marginal bone loss and better esthetic results than simple placement of immediate implants. However, a lack of homogeneity was found in evaluation methods of the different outcomes, surgical procedures and prosthetic management. CONCLUSIONS: Based on the results of this review, it is possible to suggest that socket shield technique could be a good alternative in terms of alveolar bone maintenance, marginal bone stability and aesthetic outcomes in immediate implant treatment. However, it is not possible to recommend this technique as an alternative treatment with the same long-terms predictability as conventional immediate implants.

Clinical performance of alveolar ridge augmentation with xenogeneic bone block grafts versus autogenous bone block grafts. A systematic review.

INTRODUCTION: This systematic literature review aimed to evaluate the feasibility of xenogeneic bone blocks for ridge augmentation compared with autogenous blocks by analyzing block survival rates, block resorption, subsequent implant survival rate, post-surgical complications, and histomorphometric findings. MATERIALS AND METHODS: Electronic searches were conducted in the Medline (PubMed), Web of Science and Cochrane databases, complimented by a manual search in specialist journals, for relevant articles published up to March 2020. Inclusion criteria were human studies in which the outcomes of xenogeneic bone block grafts were evaluated by means of their survival rates and subsequent implant survival rates. RESULTS: Sixteen articles fulfilled the inclusion criteria and were analyzed. 333 patients were recruited with a total of 337 xenogeneic bone blocks and 82 autogenous bone blocks, showing block failure rates of 6.82% and 6.1%, respectively. Bone gain, in both height and width, was similar among xenogeneic and autogenous bone blocks, but autogenous bone blocks suffered greater resorption. Implant survival rates were slightly lower for xenogeneic bone blocks. Histological and histomorphometric analysis observed more bone formation and less residual bone substitute with autogenous bone blocks than xenogeneic bone blocks. CONCLUSIONS: Atrophic alveolar crest reconstruction with xenogeneic bone block grafts would appear to offer a viable alternative to autogenous bone block grafts, obtaining similar block graft failure rate, fewer sensitive postoperative complications but a slightly lower implant survival rate. Further investigations generating long term data are needed to confirm the feasibility of xenogeneic bone blocks in different clinical scenarios.

Effectiveness of the bone ring technique and simultaneous implant placement for vertical ridge augmentation: a systematic review.

BACKGROUND: Dimensional changes after dental extraction frequently lead to situations in which bone augmentation procedures are required prior to dental implant placement. Bone ring technique (BRT) has been described as a one-stage approach to restore vertical alveolar ridge defects, in which an autogenous or allogeneic cortico-cancellous bone block graft is stabilized with a dental implant inserted simultaneously. The objective of this systematic review was to evaluate the clinical performance of BRT. MATERIALS AND METHODS: This review was conducted according to PRISMA guidelines. An electronic search was conducted in four databases: (1) The National Library of Medicine (MEDLINE/PubMed) via Ovid; (2) Web of Science (WOS); (3) SCOPUS; and (4) Cochrane Central Register of Controlled Trials (CENTRAL). The Newcastle-Ottawa Quality Assessment Scale and The Joanna Briggs Institute Critical Appraisal tool were used to assess the quality of evidence in the studies reviewed. RESULTS: Sixteen studies with a total of 186 patients treated with 219 bone rings bocks were included in the review. The studies showed a mean bone gain of 4.94 mm, mean bone resorption of 0.83 mm, and mean marginal bone loss of 0.57 mm after a mean follow-up period of 13.35 months. A mean bone ring survival rate of 97.26% and implant survival rate of 94.97% were recorded. CONCLUSIONS: BRT would appear to be an adequate alternative technique for restoring single vertical alveolar ridge defects with simultaneous dental implant placement. However, further studies comparing this technique with other vertical ridge augmentation procedures in different clinical scenarios are needed to confirm the present results.

Manejo quirúrgico del paciente con patología pseudoquística sinusal: a propósito de un caso / Surgical management of the patient with sinusal pseudocyst pathology: a case report

Introducción: la patología sinusal puede comprometer el éxito del tratamiento de implantes. Existe una elevada incidencia de patología sinusal. El tratamiento de esta patología puede implicar a otros profesionales, lo que supone un mayor coste sanitarios y demora en la realización de los tratamientos de implantes. El objetivo del presente artículo es presentar un caso clínico representativo de la patología pseudoquística del seno maxilar y una alternativa de su manejo quirúrgico simultáneo a la regeneración ósea requerida para su posterior rehabilitación mediante implantes, así como actualizar la evidencia científica disponible. Caso clínico: se presenta una paciente de 46 años con una lesión pseudoquística sinusal que es remitida para rehabilitar mediante implantes en 1.4 y 1.7, por movilidad y dolor en relación a prótesis fija dentosoportada en maxilar derecho. Se realiza el tratamiento quirúrgico de exodoncias, elevación de seno maxilar y eliminación de la lesión pseudoquística de manera simultánea. Discusión: existe controversia sobre el momento idóneo para realizar el tratamiento sinusal. Algunos estudios muestran éxito de la cirugía endoscópica simultáneamente a la eliminación de la fuente odontogénica. Otros han demostrado que realizar primero la cirugía sinusal tiene el mismo porcentaje de curación que realizar primero el tratamiento odontológico. Conclusión: el diagnóstico de la patología y la planificación quirúrgica deben tener en cuenta el tipo de patología, la extensión y las necesidades de tratamiento del paciente. El manejo quirúrgico de la patología sinusal de manera simultánea a la regeneración ósea es una alternativa segura y beneficiosa para el paciente. (AU)

Introduction: Sinus pathology can compromise the success of implant treatment. There is a high incidence of sinus pathology. The treatment of this pathology may involve other professionals, which means higher healthcare costs and delays in carrying out implant treatments. Besides updating available scientific evidence, the objective of this article is to present a representative clinical case of pseudocystic pathology of the maxillary sinus and an alternative to its simultaneous surgical management in the bone regeneration required for subsequent rehabilitation using implants. Clinical case: A 46-year-old patient with a pseudocystic sinus lesion, referred for rehabilitation using implants in 1.4 and 1.7, due to mobility and pain in relation to a tooth-supported fixed prosthesis in the right maxilla. The surgical treatment, consisting of extractions, maxillary sinus elevation and removal of the pseudocystic lesion, was performed simultaneously. Discussion: There is controversy about the ideal time to perform sinus treatment. Some studies show success of endoscopic surgery simultaneously with removal of the odontogenic source. Others have shown that performing sinus surgery first has the same cure rate as performing dental treatment first. Conclusion: Pathology diagnosis and surgical planning must take into account the type and extent of the pathology and the treatment needs of the patient. Surgical management of sinus pathology simultaneously with bone regeneration is a safe and beneficial alternative for the patient. (AU)

Is it possible to predict neurosensory alterations in impacted lower third molar removal based on preoperative imaging procedures? A prospective cohort study / ¿Es posible predecir alteraciones neurosensoriales en la extracción del tercer molar inferior impactado basándose en procedimientos de imagen preoperatorios? Un estudio de cohorte prospectivo

Background: Surgical extraction of the lower third molar (LTM) may trigger neurosensory injury of the inferioralveolar nerve, making extraction a real challenge. This study set out to assess whether is it possible to predictneurosensory alterations from preoperative imaging.Material and Methods: A total of 99 patients underwent 124 impacted lower third molar (ILTM) surgeries. Priorto surgery, panoramic and CBCT images were evaluated in an attempt to predict a neurosensory disturbance.Preoperative data (ILTM position, panoramic radiograph signs, inferior alveolar nerve (IAN) location and its con-tact with the ILTM roots) and intra/postoperative findings (extraction difficulty and sensitivity alterations) wererecorded. Descriptive and bivariate data analysis was performed. Statistical comparison applied the chi-squaretest, Fisher test, and one-way ANOVA test. Statistical significance was established with a confidence interval (CI)of 95%.Results: In 4.03% of cases, patients experienced neurosensory alterations. Of 124 ILTM positions in panoramicradiographs, 76 cases were considered to exhibit a potential neurosensory risk as they presented two or more typesof superimposed relationships between ILTM and mandibular canal. Of these, alterations were reported in onlythree cases (3.95%). Of the 48 remaining ILTM images presenting only one sign, neurosensory alterations wereobserved in two cases (4.17%). No permanent alterations were recorded in any of the five cases observed.Conclusions: Within the limitations of the present study, prediction of neurosensory alterations prior to ILTMextraction by means of preoperative imaging did not show a significant statistical correlation with post-surgicalincidence. Nevertheless, interruption of the canal´s white line (ICWL) or a diversion of the canal (DC) may predictan increased risk of IAN injury.(AU)

Utilización de dentina autógena para relleno del gap en el implante inmediato postextracción: a propósito de un caso clínico con seis meses de seguimiento / Autogenous dentin graft in the immediate post-extractive implant gap: six-month follow up of a clinical report

Introducción: las extracciones dentarias producen una reabsorción horizontal y vertical de la cresta alveolar, que se puede minimizar con algunas técnicas quirúrgicas, como la colocación de implantes inmediatos post-extracción, asociados al empleo de biomateriales. Caso clínico: se presenta el caso clínico de una mujer de 48 años, que acudió a consulta presentando dolor intenso en la zona del incisivo lateral superior izquierdo, asociado a una profundidad de sondaje de 12 mm. Se realizó la exodoncia del 2.2, y la colocación de un implante inmediato post-extracción, utilizando la dentina de la raíz extraída, para rellenar el gap entre el implante y la cortical vestibular, mostrando buenos resultados clínicos y radiográficos a los 6 meses tras la intervención. Discusión: aunque en la actualidad se utilizan multitud de biomateriales para reducir la reabsorción ósea en los implantes inmediatos post-extracción, ninguno de ellos parece tener mejores resultados que el resto, suponiendo en este sentido la dentina autógena una alternativa útil al tratarse de un material autólogo, con buenas tasas de aceptación por parte de los pacientes, y teniendo unas propiedades adecuadas de osteoconducción y osteoinducción.Conclusiones: la dentina autógena presenta buenos resultados clínicos y radiográficos para rellenar el gap en implantes inmediatos post-extracción (AU)

Introduction: Tooth extraction produces an horizontal and vertical resorption of the alveolar ridge, which can be reduced by many surgical techniques, such as immediate post-extractive implants, in combination with bone substitutes. Clinical case: A clinical case of a 48-year-old woman is presented, who went to dental clinic referring pain in her upper lateral incisor, associated to high probing depth. An immediate post extractive implant was placed, employing autogenous dentin from the root extracted, to fill the gap between the implant and the buccal plate, showing good clinical and radiographic evolution 6 months after surgery. Discussion: Although nowadays there are different bone substitutes to reduce bone resorption when immediate implants are placed, they have similar results, becoming autogenous dentin an useful alternative, which is an autologous material, with good patient acceptation rates and osteoconductive and osteoinductive properties.Conclusion: Autogenous dentin shows promising clinical and radiographical results when it is used to fill the gap in the post-extractive immediate implant (AU)

Burnout syndrome assessment among Spanish oral surgery consultants: A two populations comparative pilot study

Background: The professional Burnout Syndrome (BOS) or Burnout is considered a professional disease made up of three interrelated dimensions (emotional exhaustion, depersonalization and lack of personal fulfillment). BOS has been documented to most severely affect the healthcare professions, especially dentists. On the other hand, its appearance has been documented at an early age, during dental training. However, there are no studies that analyze its incidence in professionals dedicated to Oral Surgery and Implantology, determining the age of onset and related factors. Material and Methods: The modified Maslach questionnaire was carried out anonymously among the professors and students of the Master of Oral Surgery and Implantology at the Complutense University of Madrid. A total of 36 participants were enrolled in this study and the results of the modified Maslach Questionnaire were established into four groups [1st year (n=6), 2nd year (n=6), 3rd year (n=6) postgraduate students and clinical teachers (n=18)]. The following variables were recorded: Age, sex, years of experience, weekly hours of work, dedication on weekends and scope of work. The statistical analysis performed included Pearson's correlation, analysis of variance, Student's t-test, F-Anova, Chi-Square and Gamma correlation. Statistical Significance of the tests was established of p≤0.05. Results: 36 questionnaires were analyzed, of which 22.2% (n = 8) presented BOS, and 77.8% (n = 28) a medium risk of suffering it. The mean values and standard deviation ​​of emotional exhaustion (7.50 ± 2.43; 9.83 ± 4.12; 15.83 ± 6.21; 30.22 ± 7.86), depersonalization (5.50 ± 1.23; 50 ± 3.27; 11.33 ± 1.75; 17.56 ± 4.13), low personal fulfillment (39.67 ± 3.72; 39.33 ± 2.34; 43.17 ± 3, 55; 37.33 ± 5.51) and professional burnout (54.33 ± 2.66; 61.67 ± 2.88; 70.33 ± 5.43; 85.11 ± 9.05) in the four groups respectively. A significant association was found in the appearance of emotional exhaustion and depersonalization, years of experience, weekly work hours and the work environment. Conclusions: BOS is a disease that can appear from 30 years of age, after 5 years of professional experience and when there is a clinical consultation of 40 hours a week. Oral Surgery and Implantology seems to be a risk activity for the manifestation of depersonalization.(AU)

Dental management in patients with antiplatelet therapy: A systematic review.

INTRODUCTION: Cardiovascular diseases are the most frequent cause of death in the Western world. Its treatment frequently needs therapy with antiplatelet agents, which increases the haemorrhage risk after oral surgical procedures. The aim of this study is to present a review on the dental management of the patients under antiplatelet treatment. MATERIAL AND METHODS: A systematic review was carried out following PRISMA recommendations including studies searched in Pubmed-Medline, Embase and Cochrane databases. RESULTS: The current trend is to maintain the treatment during the surgical procedure, assuring a good control of the haemorrhage with local haemostatic measures. However, new antiplatelet drugs protocols are not firmly established. CONCLUSIONS: In spite of the existing recommendations, it is always advisable to consult with the internist or cardiologist of every patient before any intervention.

Eficacia de los concentrados plaquetarios en distracción ósea alveolar: una revisión de la bibliografía / Efficacy of platelet concentrate application in alveolar distraction osteogenesis technique: a review

INTRODUCCIÓN: La distracción ósea alveolar (DOA), es una técnica de aumento óseo predecible, con resultados exitosos a medio y largo plazo. El uso de concentrados plaquetarios (CP) ha demostrado ser beneficioso en la cicatrización de tejidos blandos y la reparación y regeneración ósea, mediante liberación de factores de crecimiento. Se ha probado el uso de CP durante la distracción de huesos largos, obteniéndose resultados beneficiosos. El objetivo de esta revisión bibliográfica fue analizar los resultados clínicos de la combinación de la DOA y el uso de CP. MATERIAL Y MÉTODO: Se realizó una revisión bibliográfica en tres bases de datos electrónicas sin restricciones. Además, la búsqueda electrónica fue completada con una manual, para identificar cualquier artículo adicional de relevancia. RESULTADOS: Se seleccionaron 6 artículos; dos ensayos clínicos aleatorizados en humanos, dos estudios de experimentación animal y dos casos clínicos. Los artículos incluyeron un total de 27 pacientes y 50 conejos, y utilizaron diferentes protocolos para la obtención de CP. Se registraron ganancias óseas de entre 6,3 mm a 25 mm. Además, tres artículos reportaron complicaciones como parestesia transitoria, infección o inclinación del segmento de transporte. CONCLUSIONES: El uso de CP durante la DOA presenta efectos positivos, disminuir el riesgo de infección y la respuesta inflamatoria, aumentar la vascularización del callo de fractura, producir una aceleración en la regeneración ósea y disminuir el periodo de consolidación. Ante la heterogeneidad de los artículos incluidos, son necesarios más estudios que esclarezcan el papel de los CP y su influencia durante la DOA

INTRODUCTION: Alveolar distraction osteogenesis (ADO) is a predictable bone augmentation technique, with successful results in the medium and long term. The use of platelet concentrates (PC) has been demonstrated to be beneficial in soft tissue healing, in bone repair and regeneration, through the release of growth factors. The use of PC has been used in combination with osteogenesis distraction of long bones, obtaining positive results. The aim of this literature review was to analyze the clinical outcomes of the combination of the alveolar distraction technique and the use of PCs. MATERIAL AND METHODS: A bibliographic review was performed in three electronic databases without time or language restrictions. In addition, the electronic search was completed by a manual, to find any additional relevant articles. RESULTS: 6 articles were selected; two human randomized clinical trials, two animal experimentation and two clinical cases. The articles included a total of 27 patients and 50 rabbits and used different protocols to obtain PCs. Bone gains of between 6.3mm to 25mm were reported. In addition, three articles reported complications such as transient paresthesia, infection, or inclination of the transport segment. CONCLUSIONS: The use of PCs during ADO has positive effects, by decreasing the risk of infection and the inflammatory response, enhancing the vascularization of the fracture callus, causing an acceleration in bone regeneration and reducing the consolidation period. Due the heterogeneity of the articles included, more studies are needed to clarify the role of PCs and their influence during ADO

Coronectomía en terceros molares inferiores / Coronectomy of the lower third molar

La extracción del tercer molar inferior es el procedimiento más frecuente dentro del campo de la cirugía bucal, siendo el daño del nervio dentario inferior una de las complicaciones más frecuentes en la extracción. Como alternativa para disminuir el riesgo de aparición de esta complicación surge la coronectomía, técnica que consiste en la eliminación de la corona dentaria manteniendo intactas las raíces dentro del hueso alveolar. El objetivo del presente artículo fue realizar una puesta al día sobre la coronectomía en terceros molares inferiores, analizando indicaciones, contraindicaciones, complicaciones y éxito de esta técnica. La coronectomía parece ser una alternativa eficaz a la extracción para la prevención de trastornos neurosensoriales en terceros molares impactados en estrecha relación con el NDI. Sin embargo, es necesaria la realización de más estudios comparando la extracción convencional con la coronectomía, con un mayor seguimiento, para conocer el éxito y las complicaciones a largo plazo de este tratamiento

The lower third molar extraction is one of the most common procedures in the field of oral surgery. Furthermore, the damage of the inferior alveolar nerve is one of the most frequent complications related to this procedure. The coronectomy was introduced in 1984, as an alternative approach that tended to reduce the occurrence of this complication. The main objective of this article is to review current evidence of coronectomy applied to mandibular third molars, analyzing indications, contraindications, complications and success of the technique. The coronectomy seems to be an effective alternative to conventional third molar extraction, for the prevention of neurosensorial disorders in impacted third molars in direct relation with inferior alveolar nerve. However, further studies are needed which compare conventional approach with coronectomy with a greater follow-up to understand the long-term morbidities and success of the technique

Medication-related osteonecrosis of the jaws (MRONJ) in cancer patients treated with denosumab VS. zoledronic acid: A systematic review and meta-analysis

BACKGROUND: The aim of the present study was to analyse the incidence, risk ratio (RR) and prognoses of two types of medication-related osteonecrosis of the jaws (MRONJ): denosumab-related osteonecrosis of the jaws (DRONJ) and Bisphosphonate-Related Osteonecrosis of the Jaws (BRONJ) in cancer patients under treatment with deno-sumab or zoledronic acid (ZA). MATERIAL AND METHODS: An electronic and manual search was conducted for randomized controlled trials (RCTs) until May 2019. Assessment of the identified studies, risk of bias and data extraction were performed independently by two reviewers. The incidence of DRONJ and BRONJ and the RR to develop MRONJ were calculated at 1 year, 2 years and 3 years of exposure. It was also calculated the odds ratio (OR) of their respective prognoses. They were calculated normalizing the values of the individual studies to 1 year, 2 years or 3 years when necessary through robust regression models using a statistical program. RESULTS: From 1.277 references identified, 8 RCTs were included, which comprised a total of 13.857 patients with a variety of neoplasms. The incidence of DRONJ in cancer patients under treatment with denosumab ranged from 0.5 to 2.1% after 1 year, 1.1 to 3.0% after 2 years, and 1.3 to 3.2% after 3 years of exposure. The incidence of BRONJ in cancer patients under treatment with ZA ranged from 0.4 to 1.6% after 1 year of exposure, 0.8 to 2.1% after 2 years, and 1.0 to 2.3% after 3 years of exposure. Statistically significant differences were found between de-nosumab and ZA in the risk of developing MRONJ after 1, 2 and 3 years of exposure. Nevertheless, there were no significant differences in terms of patient prognosis. CONCLUSIONS: Denosumab is associated with a significantly higher risk of developing MRONJ compared to ZA. Nevertheless, no differences were found in its prognoses
