The Use of Platelet-Rich Fibrin (PRF) in the Management of Dry Socket: A Systematic Review.

Dry socket or alveolar osteitis is a common postoperative complication following tooth extraction, characterized by severe pain due to the disintegration of the blood clot within the socket. Various factors contribute to its development, such as traumatic extraction, patient age and sex, smoking, and anesthetic use. To mitigate this condition, socket preservation techniques, including the use of bone substitute materials, have been employed. Platelet-rich fibrin (PRF) has emerged as a promising biomaterial, enhancing healing and reducing the incidence of dry socket. Materials and Methods: This systematic review, adhering to the PRISMA guidelines and registered with PROSPERO (ID: CRD 578018), examines the efficacy of PRF in managing dry socket by analyzing studies from PubMed, Scopus, and Web of Science published between January 2013 and May 2024. Boolean keywords have been used in the search strategy: ("Treatment") AND ("Dry Socket") AND ("Platelet Rich Fibrin" OR "PRF"). A total of 738 publications were found using the electronic database search. After the screening phase, 13 records were chosen for qualitative analysis. The results from multiple clinical trials and comparative studies indicate that PRF significantly reduces postoperative pain, expedites healing, and lowers the incidence of Alveolar Osteitis. Despite promising results, further large-scale, randomized studies are needed to validate PRF as a standard treatment for dry socket.

The effects of chlorhexidine gel and tranexamic acid application after tooth extraction on the risk of alveolar osteitis formation: a double blind clinical study.

BACKGROUND: Alveolar osteitis(AO), one of the most common complications occurring in 1-10% of cases following tooth extraction, occurs due to the disruption of clot formation in the extraction socket. This study aims to evaluate the effect of using absorbable gelatin sponge, chlorhexidine gel, and tranexamic acid agents on the development of AO following extraction. METHODS: Between March and October 2023, the teeth of 98 healthy patients (average age: 38, range: 19-62) with extraction indications were extracted at Recep Tayyip Erdogan University, Faculty of Dentistry, Department of Oral and Maxillofacial Surgery. 113 extraction sockets(85 molars and 28 premolars) were randomly treated with absorbable gelatin sponge(AGS), chlorhexidine gel with AGS, and tranexamic acid with AGS. Pain and edema levels were recorded using visual analog scale(VAS) ranging from 0 to 10 by the patients. Additionally, presence of halitosis, trismus and exposed bone was noted on forms on 3rd and 7th days (recorded as present or absent). The study prospectively aimed to prevent AO using 3 different dental agents in the extraction sockets. Statistical analyses of the study were conducted using the SPSS software package. RESULTS: Alveolitis was observed in 12 out of 113 tooth extractions(%10.6). Pain and edema scores significantly decreased in absorbable gelatin sponge group on the 7th day (p < 0.05). Pain score on the 7th day in chlorhexidine group and age, edema score on the 7th day in tranexamic acid group, were found to be significantly higher (p < 0.05). CONCLUSION: Incidence of AO, can be reduced by placing agents in the extraction socket, preventing post-extraction pain experienced by patients. CLINICAL TRIALS ID: NCT06435832.

Postextraction infections, prevention, and treatment.

Postoperative infection is one of the most common complications of tooth extraction. It may manifest as localized infection or develop to systemic infection. Clinically, oral surgeons can prevent postoperative infections by urging patients to strengthen oral hygiene, applying antibiotics in a rational and compliant manner, and choosing appropriate surgical methods for tooth extraction. For the treatment of infection, the oral surgeon should formulate a response strategy on the basis of different diagnoses. For local infections such as dry socket, delayed alveolar osteitis, gap infection, and marginal osteomyelitis of the jaws, the infection can be controlled by local debridement, therapeutic use of antibiotics, and incise and drain if necessary. For patients suspected of necrotizing fasciitis, timely extensive debridement should be made to reduce the area of tissue necrosis. For those who have received radiotherapy or anti-resorptive drugs, tooth extraction should follow the recommendations of the relevant clinical guidelines or expert consensus to minimize the risk of osteonecrosis of the jaws. For patients with poor systemic health or dysfunction of the immune system, attention should be paid to identifying infective endocarditis and intracranial infection to ensure the life safety of patients. In this study, the author intends to combine literature review and clinical experience to tackle postextraction infection and its prevention to provide a reference for colleagues on oral and maxillofacial surgery.

Investigation of alveolar osteitis and the effectiveness of laser treatment: a unified Meta-analysis and review of the literature.

BACKGROUND: Post-tooth extraction, dry socket is a frequently encountered complication, causing substantial pain and hindering the healing process. Conventional approaches to manage this condition have traditionally involved the use of antiseptic dressings to diminish bacterial presence and facilitate healing. This study aims to assess the efficacy of laser therapy in the symptomatic treatment of alveolitis. METHODS: A literature search was conducted on PubMed, Embase, Scopus, Google Scholar, Web of Science, focusing on publications from 1998 to 31/01/2024 using relevant keywords. The combination of "laser" and "dry socket" was executed through the boolean connection AND. RESULTS: At the conclusion of the study, a total of 50 studies were identified across the three search engines, with only three selected for the current systematic study and meta-analysis. The meta-analysis indicated that laser treatment proves effective in addressing alveolitis compared to Alvogyl. However, the correlation between the two was not highly significant. CONCLUSION: These findings suggest that laser therapy may serve as a viable alternative to traditional treatments for dry socket. This minimally invasive procedure has the potential to alleviate pain and promote healing with fewer associated side effects."

Prevalence of fibrinolytic alveolitis following extraction of impacted mandibular third molars: A systematic review and meta-analysis.

Our research aims to assess the prevalence of alveolar osteitis (AO) following impacted mandibular third molar extractions and investigate the impact of potential moderating factors on this occurrence. Two independent reviewers conducted a comprehensive systematic literature search across Medline, Scopus, and Google Scholar databases. The pooled prevalence, accompanied by 95 % confidence intervals (CI), was calculated. Quality assessments, outlier and influential analyses were performed. Subgroup and meta-regression analysis were conducted in order the effect of categorical and continuous variables on the estimated prevalence to be investigated. Our meta-analysis included twenty-eight eligible studies, encompassing a total of 41,859 impacted mandibular third molar extractions. The overall prevalence of dry socket (DS) following impacted mandibular third molar extractions was estimated at 6.7 % (95 % CI 4.6-9.1 %), indicating considerable heterogeneity among the studies. No study was identified as critically influential, and meta-regression analysis did not pinpoint any potential sources of heterogeneity. This study highlights the imperative for future well-constructed prospective and retrospective investigations to deepen our understanding of the etiological nuances and refine management approaches for this prevalent postoperative complication.

Oral manifestations in women using hormonal contraceptive methods: a systematic review.

OBJECTIVES: To investigate the oral manifestations in women of reproductive age using hormonal contraceptive methods. MATERIALS AND METHODS: This review is based on the PRISMA statement. A literature search incorporated observational studies from the last 21 years. An investigative question was formulated using the PICO model, studies were selected, and a quality analysis was performed using the modified STROBE guidelines. A bibliometric analysis was performed, and the data were examined. RESULTS: Thirteen articles were included, with the majority evaluating periodontal status. Others analyzed factors such as the presence of alveolar osteitis, oral candidiasis, and salivary microbiome dysbiosis. Ten articles were deemed to have a low risk of bias. CONCLUSIONS: Hormonal contraceptives may increase the risk of alveolar osteitis following tooth extraction and increase the presence of the Candida species in the oral cavity. They also affect the periodontium, such as the frequent development of gingivitis, but do not lead to changes in the salivary microbiome. CLINICAL RELEVANCE: The increasing number of women using hormonal contraceptives and the knowledge that these contraceptives can produce oral cavity alterations underscore the need to evaluate the oral manifestations found in these women.

Risk factors for oral infection and dry socket post-tooth extraction in medically complex patients in the absence of antibiotic prophylaxis: A case-control study.

INTRODUCTION: Dry socket and infection are complications of tooth extractions. The objective was to determine risk factors for post-extraction complications in patients without antibiotic prophylaxis stratified by early- and late-complications and complication type (oral infection and dry socket). METHODS: Retrospective, case (with complications)-control (without complications) study of patients (n = 708) who had ≥1 extraction performed at any Veterans Health Administration facility between 2015-2019 and were not prescribed an antibiotic 30 days pre-extraction. RESULTS: Early complication cases (n = 109) were more likely to be female [odds ratio (OR) = 2.06; 95% confidence interval (CI):1.05-4.01], younger (OR = 0.29; 95% CI:0.09-0.94 patients ≥ 80 years old, reference:18-44 years), Native American/Alaska Native (OR = 21.11; 95% CI:2.33-191.41) and have fewer teeth extracted (OR = 0.53 3+ teeth extracted; 95% CI:0.31-0.88, reference:1 tooth extracted). Late complication cases (n = 67) were more likely to have a bipolar diagnosis (OR = 2.98; 95% CI:1.04-8.57), history of implant placement (OR = 8.27; 95% CI:1.63-41.82), and history of past smoking (OR = 2.23; 95% CI:1.28-3.88). CONCLUSION: Predictors for post-extraction complications among patients who did not receive antibiotic prophylaxis were similar to prior work in cohorts who received prophylaxis. Unique factors identified in a medically complex population included being younger, Native American/Alaska Native, having mental health conditions, history of a dental implant, and fewer teeth extracted.

Possible roles of short-chain fatty acids produced by oral bacteria in the development of alveolar osteitis.

PURPOSE: Alveolar osteitis (dry sockets) is a painful condition characterized by a limited immune response. It is typically caused by the removal of blood clots from extracted tooth sockets, which leads to the fermentation of trapped food remnants by oral bacteria in the cavities, producing high concentrations of short-chain fatty acids (SCFAs). This study examined the effects of SCFAs on immunity and bone metabolism. METHODS: Mouse macrophage Raw264.7 cells were treated with oral bacteria supernatants or SCFA mixtures, and inducible nitric oxide synthase (iNOS) levels were determined by western blot. The same cells were treated with SCFA mixtures in the presence of receptor activator of nuclear factor-kappa B ligand (RANKL), and osteoclast-like cells were counted. MC3T3-E1 cells were treated with SCFA mixtures and stained with alizarin red S. RESULTS: Raw264.7 cells treated with oral bacterial culture supernatants of Porphyromonas gingivalis and Fusobacterium nucleatum inhibited lipopolysaccharide (LPS)-induced iNOS production, likely due to SCFA content. SCFA mixtures mimicking these supernatants inhibited the number of RANKL-induced tartrate-resistant acid phosphatase (TRAP)-positive cells and MC3T3-E1 cell mineralization. CONCLUSION: These data suggest that SCFAs produced by P. gingivalis and F. nucleatum may reduce the inflammatory response and mildly induce mineralization of the alveolar walls. These results may contribute to the understanding of alveolar osteitis.

Er:YAG Laser Therapy on Alveolar Osteitis After Mandibular Third Molar Surgery: A Randomized Controlled Clinical Study.

Background: Alveolar osteitis (AO) or "dry socket" affects the quality of life of patients, and there is a high clinical demand for its effective treatment. Objective: To evaluate the effect of Er:YAG laser therapy (ErLT) on AO after mandibular third molar surgery. Methods: Eighty-three patients were randomly divided into Er (n = 43) and control groups (n = 40). In the Er group, the Er:YAG laser (2940 nm; AT Fidelis Fotona, Ljubljana, Slovenia) was used to irradiate the AO site directly in micro short-pulsed mode (pulse duration 0.1 ms, pulse energy 100 mJ, frequency 40 Hz, water 4, and air 2) until all debris and necrotic material had been removed, exposing fresh bone and soft tissue surfaces with blood exudation. The control group received mechanical therapy until the treated lesions resembled those in the Er group. Pain assessment was performed at baseline and on days 1-7 post-intervention using the visual analog scale (VAS). Wound healing was assessed using the wound healing index (WHI). The operating times of the two therapies were also recorded. Results: Group Er had lower VAS scores than the control group on days 1-3 (p = 0.00). There was no significant difference between the two groups on days 4-7 (p = 0.15). The WHI scores were better in the Er group than those in the control group (t = 2.65, p = 0.01), especially in terms of redness (t = 2.70, p = 0.01). There was no significant difference in the operating time between the two groups (t = 0.76, p = 0.45). Conclusions: Compared with mechanical therapy, ErLT for AO provides rapid pain relief and improved wound healing.

Complicações odontológicas em indivíduos com insuficiência renal crônica: estudo retrospectivo / Dental complications in chronic renal failure individuals: a retrospective study

A doença renal crônica em estágio terminal pode levar a alterações sistêmicas que tornam o manejo clínico odontológico desses indivíduos desafiador, especialmente se os procedimentos forem invasivos. As preocupações incluem alteração do metabolismo de drogas, da resposta imunológica e do metabolismo ósseo, além do risco aumentado de sangramento e discussão sobre risco aumentado para endocardite infecciosa. O objetivo deste estudo retrospectivo foi conhecer a frequência e o tipo de complicações durante e após execução de procedimentos odontológicos em indivíduos com insuficiência renal crônica em diálise (IRC-D), atendidos no Centro de Atendimento a Pacientes Especiais (CAPE) da Faculdade de Odontologia da USP (FOUSP). Adicionalmente, comparamos a quantidade e o tipo de complicações entre os indivíduos que usaram antibiótico profilático e aqueles que não usaram, antes dos procedimentos odontológicos. Para tanto desenvolvemos um formulário específico para este estudo, no qual compilamos as informações relativas aos períodos trans e pós-operatórios de procedimentos odontológicos realizados nos pacientes com IRC em diálise. Nossa hipótese era a de que a prevalência de complicações durante e após os procedimentos odontológicos de indivíduos com IRC em diálise fosse baixa, e que ouso do antibiótico prescrito profilaticamente não interferiria na qualidade dareparação ou na incidência de complicações relacionadas aos procedimentos odontológicos. Analisamos retrospectivamente 225 prontuários de pacientes com IRC em diálise atendidos no CAPE-FOUSP desde 1990 até os dias atuais. Desse total, 130 eram pacientes do sexo masculino e do 95 do feminino. A idade média destes indivíduos foi de 48,4 anos. As principais doenças de base que levaram a ocorrência da IRC-HD foram a hipertensão arterial sistêmica (48 pacientes) e o diabetes mellitus (23 pacientes). Nos 225 pacientes, 1.390 procedimentos odontológicos foram realizados, dos quais 856 foram não invasivos, 443 invasivos e 91 tratamentos endodônticos. Dentre os procedimentos invasivos, houve 259 exodontias. Antes de 80 das 259 intervenções cirúrgicas (31%) houve a prescrição de antibiótico profilático em diferentes posologias; em 29 exodontias (11%) foram utilizados hemostáticos locais no momento da realização da sutura. Foram descritos nos prontuários 16 casos de sangramento transoperatório (6%), 5 casos de sangramento pós-operatório (2%) e 2 casos de complicação pós-operatória (0,8%), definidos como uma alveolite e uma infecção alveolar. Nossos resultados permitiram nos concluir que a incidência de complicações após exodontias é baixa e que o uso de antibiótico profilático (AP) não interferiu nessa incidência.

Prevalence and factors associated with dry socket following routine dental extractions.

BACKGROUND: Dry socket (DS) or fibrinolytic osteitis is a relatively common complication that can occur following tooth extraction. This study aimed to determine the prevalence of DS and identify its associated predictive and mediating variables. MATERIAL AND METHODS: This study is classified as prospective observational, cross-sectional, and multicenter. Patients were consecutively selected in accordance with established criteria for tooth extraction. Data on patient demographics, surgical procedures and postoperative outcomes were collected. Nominal variables were analyzed using the Chi-Square Test, while associations involving ordinal values or considering counts or layers were examined using the Kendall's Tau-B Test or Mantel-Haenszel Test for trend. The GLM Mediation Model was employed to investigate potential mediation or indirect effects or potential underlying mechanisms of predictive variables on the development of DS. Two-tailed significance level of p ≤0.05 was considered statistically significant. RESULTS: A total of 1,357 patients undergoing routine dental extractions were included. DS was observed in 13 patients (prevalence of 1%). DS was associated with younger patients (under 50 years old), longer procedures, and the presence of surgical accidents, but only when mediated by surgical complexity. Smoking, particularly in combination with complex surgeries and surgical accidents, was associated with DS. Postoperative pain for more than two days and reported at moderate to high levels, emerged as a potential warning sign for DS. The use of antibiotics was found to significantly reduce the risk of DS (RR reduction of 36% and absolute risk reduction of 0.63%). CONCLUSIONS: Routine dental extractions revealed a 1% prevalence of dry socket. The obtained results suggests that DS is a multifactorial condition influenced by various factors, including gender, age, smoking, antibiotic prescription and surgical factors such as length, technique and accidents, nevertheless, those associations were observed mainly considering the influence of one variable on another.

Antibiotic prophylaxis in the prevention of dry socket and surgical site infection after lower third molar extraction: a network meta-analysis.

Clinicians frequently prescribe systemic antibiotics after lower third molar extractions to prevent complications such as surgical site infections and dry socket. A systematic review of randomised clinical trials was conducted to compare the risk of dry socket and surgical site infection after the removal of lower third molars with different prophylactic antibiotics. The occurrence of any antibiotic-related adverse event was also analysed. A pairwise and network meta-analysis was performed to establish direct and indirect comparisons of each outcome variable. Sixteen articles involving 2158 patients (2428 lower third molars) were included, and the following antibiotics were analysed: amoxicillin (with and without clavulanic acid), metronidazole, azithromycin, and clindamycin. Pooled results favoured the use of antibiotics to reduce dry socket and surgical site infection after the removal of a lower third molar, with a number needed to treat of 25 and 18, respectively. Although antibiotic prophylaxis was found to significantly reduce the risk of dry socket and surgical site infection in patients undergoing lower third molar extraction, the number of patients needed to treat was high. Thus, clinicians should evaluate the need to prescribe antibiotics taking into consideration the patient's systemic status and the individual risk of developing a postoperative infection.

Outcomes of Coronectomy and Total Odontectomy of Impacted Mandibular Third Molars.

OBJECTIVE: The aim of this research was to evaluate the surgical complications and neurosensory deficits after coronectomy and the complete removal of mandibular third molars. METHODS: The study sample included patients requiring surgical removal of mandibular third molars. A coronectomy was conducted on 220 teeth showing signs of close proximity to the inferior alveolar canal. A complete extraction was performed on 218 teeth with no risk signs. The patients were evaluated at 1 week and 1, 3, 6, 12, and 24 months after surgery for pain, swelling, neurologic deficit, dry socket, postoperative bleeding, infection, root migration, and eruption. RESULTS: No significant difference was noted in pain and swelling; however, bleeding and dry socket were significantly higher in the odontectomy group (P = .017). The inferior alveolar nerve deficit was higher in the odontectomy group (3.7%) than the coronectomy group (0.5%) (P = .017). The percentage and distance of root migration of coronectomised teeth at 3, 6, and 12 months were 60% (2.37 ± 0.96 mm), 66% (3.35 ± 0.86 mm), and 74% (3.85 ± 0.93 mm), respectively. CONCLUSIONS: Coronectomy is a safe procedure and should be performed when the roots are closely associated with the mandibular canal. Although root migration is common, the likelihood of root exposure is low and roots rarely need removal.

Hyaluronic acid in tooth extraction: a systematic review and meta-analysis of preclinical and clinical trials.

OBJECTIVES: To assess whether in animals or patients with ≥ 1 tooth extracted, hyaluronic acid (HyA) application results in superior healing and/or improved complication management compared to any other treatment or no treatment. MATERIALS AND METHODS: Three databases were searched until April 2022. The most relevant eligibility criteria were (1) local application of HyA as adjunct to tooth extraction or as treatment of alveolar osteitis, and (2) reporting of clinical, radiographic, histological, or patient-reported data. New bone formation and/or quality were considered main outcome parameters in preclinical studies, while pain, swelling, and trismus were defined as main outcome parameters in clinical studies. RESULTS: Five preclinical and 22 clinical studies (1062 patients at final evaluation) were included. In preclinical trials, HyA was applied into the extraction socket. Although a positive effect of HyA was seen in all individual studies on bone formation, this effect was not confirmed by meta-analysis. In clinical studies, HyA was applied into the extraction socket or used as spray or mouthwash. HyA application after non-surgical extraction of normally erupted teeth may have a positive effect on soft tissue healing. Based on meta-analyses, HyA application after surgical removal of lower third molars (LM3) resulted in significant reduction in pain perception 7 days postoperatively compared to either no additional wound manipulation or the application of a placebo/carrier. Early post-operative pain, trismus, and extent of swelling were unaffected. CONCLUSIONS: HyA application may have a positive effect in pain reduction after LM3 removal, but not after extraction of normally erupted teeth. CLINICAL RELEVANCE: HyA application may have a positive effect in pain reduction after surgical LM3 removal, but it does not seem to have any impact on other complications or after extraction of normally erupted teeth. Furthermore, it seems not to reduce post-extraction alveolar ridge modeling, even though preclinical studies show enhanced bone formation.

Further evidence confirms the association between smoking and dry socket: a motivational opportunity for tobacco cessation.

DESIGN: A systematic review and meta-analysis of observational studies. DATA SOURCES: Electronic search included PubMed, Scopus, and Web of Science databases up to March 2022 using appropriate keywords. SELECTION CRITERIA: The review included all observational studies (case-control, cohort and cross-sectional studies) published in English after 2000, comparing the prevalence of dry socket between smokers and non-smokers after simple or surgical tooth extraction. Exclusion criteria included patients with other post-extraction complications, prevalence of different risk factors, and unrelated study designs (literature reviews, case reports, expert opinion, and conference reports). DATA EXTRACTION AND SYNTHESIS: Two independent investigators screened the records (by title, abstract, and full text), and selected the eligible studies according to the predefined criteria. Collected data from each study included author name and country, year of publication, gender and age of patients, smoking status, inclusion and exclusion criteria, medical history and oral hygiene, prevalence of dry socket, type of tooth and extraction technique, symptoms and treatment. Risk of bias was assessed according to the (NHLBI, NIH) Quality Assessment Tool For Observational Cohort and Cross-Sectional Studies, while the level of evidence was assessed using the classification of the Oxford Centre for Evidence-Based Medicine levels for diagnosis. Two independent reviewers conducted the assessments, and any disagreements were addressed through discussion. RESULTS: Eleven studies from ten different countries representing a total of 10,195 patients (3007 smokers and 7188 non-smokers) were included in the final analysis. Nine studies were classified as having "good" quality and two as "intermediate," while all of the studies have the third or fourth level of evidence (through 5-graded scale). The prevalence of dry socket in smokers was about 13.2% (95% CI: 5.8-23.1%) and in non-smokers about 3.8% (95% CI: 2.1-6.0%). Meta-analysis showed that regular tobacco smoking was associated a more than 3-fold increase in the odds of dry socket after tooth extraction. CONCLUSION: Despite heterogeneity among the included studies (different age groups and types of teeth extracted), there was a consistent association between cigarette smoking and an elevated risk of developing dry socket post tooth extraction.

The Communnity Health Center (CESFAM) of San Pedro de Atacama, is the only establishment of health assistance in the community and surroundings, it is imperative for Dental Surgeons to be decisive and deliver an effective solution to local demand. Determinate the prevalence of post-extraction complications of third molars in patients treated at CESFAM San Pedro de Atacama between January and October 2020. Descriptive cross- sectional study between January and October 2020. It has been done a retrospective review of manual clinical records and electronic database of dental care performed at CESFAM. Patients over 18 years old, systemically healthy or compensated ASA II, who had extracted an upper or lower third molar and who had attended a 7-day clinical check-up were included in the study. Were excluded Illegible or no follow up clinical records, patients with a history of pericoronitis up to 7 days previously, and immunocompromised patients. The frequency of postoperative complications was related to the difficulty of the intervention (mild / moderate / high) and whether the tooth was maxillary or mandibular. A descriptive and statistical analysis of the data obtained by Fisher's exact test was carried out to evaluate the association between the variables using the statistical program STATA v. 15. Between January and October 2020, 146 third molar extractions were performed; 61 were of mild difficulty (41.7 %), 58 of moderate difficulty (39.8 %) and 21 of high difficulty (18.5 %). The result of post-extraction complications reached 5.4 % (n = 8), where the most frequent complication was alveolitis. Post-extraction complications are significantly related to the level of mild difficulty (p 0,05).

Prophylactic therapy for prevention of surgical site infection after extraction of third molar: An overview of reviews.

BACKGROUND: To compare the effect of different prophylactic therapies on prevention of surgical site infection after extraction of third molars with different degree of impaction. MATERIAL AND METHODS: Systematic reviews and meta-analyses evaluating the effect of different prophylactic therapies on prevention of surgical site infection after extraction of third molars were included. An electronic search was performed in PubMed, EMBASE, and the Cochrane Database of Systematic reviews. AMSTAR 2 tool was used to evaluate the confidence in results from the included reviews. Descriptive analyses were performed. RESULTS: Six reviews were included. A significant benefit of different antibiotics to the prevention of site infection after extraction of third molars was reported. Amoxicillin/amoxicillin clavulanic acid could significantly reduce the rate of surgical site infection versus placebo. Chlorhexidine gel could significantly reduce the frequency of alveolar osteitis versus placebo. CONCLUSIONS: Based on the limited evidence, there is a significant benefit of prophylactic therapy while the comparative effect of different types of prophylactic regimes are controversial.

Corticosteroids for managing acute pain subsequent to surgical extraction of mandibular third molars: A systematic review and meta-analysis.

BACKGROUND: Corticosteroids are used to manage pain after surgical tooth extractions. The authors assessed the effect of corticosteroids on acute postoperative pain in patients undergoing surgical tooth extractions of mandibular third molars. TYPES OF STUDIES REVIEWED: The authors conducted a systematic review and meta-analysis. The authors searched the Epistemonikos database, including MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and the US clinical trials registry (ClinicalTrials.gov) from inception until April 2023. Pairs of reviewers independently screened titles and abstracts, then full texts of trials were identified as potentially eligible. After duplicate data abstraction, the authors conducted random-effects meta-analyses. Risk of bias was assessed using Version 2 of the Cochrane Risk of Bias tool and certainty of the evidence was determined using the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS: Forty randomized controlled trials proved eligible. The evidence suggested that corticosteroids compared with a placebo provided a trivial reduction in pain intensity measured 6 hours (mean difference, 8.79 points lower; 95% CI, 14.8 to 2.77 points lower; low certainty) and 24 hours after surgical tooth extraction (mean difference, 8.89 points lower; 95% CI, 10.71 to 7.06 points lower; very low certainty). The authors found no important difference between corticosteroids and a placebo with regard to incidence of postoperative infection (risk difference, 0%; 95% CI, -1% to 1%; low certainty) and alveolar osteitis (risk difference, 0%; 95% CI, -3% to 4%; very low certainty). PRACTICAL IMPLICATIONS: Low and very low certainty evidence suggests that there is a trivial difference regarding postoperative pain intensity and adverse effects of corticosteroids administered orally, submucosally, or intramuscularly compared with a placebo in patients undergoing third-molar extractions.

A modified triangular flap suture method used for inferior third molar extraction: A three-arm randomized clinical trial for the assessment of quality of life.

BACKGROUND: The purpose of this study is to explore whether decreasing the number of sutures can improve the quality of life after inferior third molar extraction. MATERIAL AND METHODS: This study used a three-arm randomized design that included 90 individuals. Patients were randomized and divided into three groups-the airtight suture group (traditional), the buccal drainage group, and the no-suture group. Postoperative measurements, including treatment time, visual analog scale, questionnaire on postoperative patient quality of life, and details about trismus, swelling, dry socket, and other postoperative complications were obtained twice and the mean values were recorded. To verify the normal distribution of the data, the Shapiro-Wilk test was performed. The statistical differences were evaluated using the one-way ANOVA and the Kruskal-Wallis test with Bonferroni post-hoc correction. RESULTS: The buccal drainage group showed a significant decrease in postoperative pain and better speech ability than the no-suture group on the 3st day, with a mean of 1.3 and 0.7 (P < 0.05). The airtight suture group also showed similar eating and speech ability, which was better than the no-suture group, with a mean of 0.6 and 0.7 (P < 0.05). However, no significant improvements were noted on the 1st and 7th days. The surgical treatment time, postoperative social isolation, sleep impairment, physical appearance, trismus, and swelling showed no statistical difference between the three groups at all measured times (P > 0.05). CONCLUSIONS: Based on the above findings, the triangular flap without a buccal suture may be superior to the traditional group and no-suture group in less pain, and better postoperative patient satisfaction in the first 3 days and may be a simple and viable option in clinical practice.

La alveolitis y sus factores de riesgo en la población adulta joven / Dry socket and its risk factors in a young adult population

Introducción: La alveolitis es la complicación más frecuente de la extracción dental, y constituye la causa más común de las consultas de Urgencias, pues los pacientes presentan dolor en el período postoperatorio. Aunque la etiología de esta afección no es muy conocida, se considera que es un trastorno multifactorial. Objetivos: Determinar el tipo de alveolitis más frecuente en la muestra objeto de estudio, así como establecer la relación entre los factores de riesgo y el tipo de alveolitis.

Introduction: dry socket is the most frequent complication after a dental extraction and constitutes the most common cause of emergency consultations, since patients have pain in the postoperative period. It is considered to be a multifactorial disorder although the etiology of this condition is not well known. Objectives: to determine the most common type of dry socket in the sample under study, as well as to establish the relationship between risk factors and the type of dry socket. Methods: a descriptive and cross-sectional study was carried out in the emergency department at "Celia Sánchez Manduley" Dental Clinic, in Santa Clara, Villa Clara, from February 2020 to June 2021. The study was carried out in a total of 51 patients who were diagnosed with dry socket. Type of dry socket and risk factors such as age, gender, history of diseases, use of contraceptive tablets, toxic habits, conditions of the oral environment, characteristics of the surgical procedure and postoperative care were the variables studied; the data was collected in a form. Results: dry socket predominated in female patients. Smoking and performing a complex surgical maneuver were the predominant risk factors.
