Dentin hypersensitivity and toothache among patients diagnosed with Molar-Incisor Hypomineralization: A systematic review and meta-analysis.

OBJECTIVES: To determine the prevalence of dentin hypersensitivity (DH) and toothache in patients with Molar-Incisor Hypomineralization (MIH); and evaluate whether patients with MIH have greater likelihood of presenting DH/toothache than controls. DATA: Studies evaluating DH/toothache in patients with MIH were included. Studies focusing on other enamel defects were excluded. SOURCES: Eight databases, including grey literature, were searched in January 2024. STUDY SELECTION: The methodological quality of studies was assessed using the Joanna Briggs Institute checklist for Cross-sectional studies. Proportion and association meta-analyses, subgrouped by diagnostic methods, were conducted. The certainty of evidence was assessed using GRADE approach. RESULTS: Fifteen studies were included in the qualitative analysis and fourteen in the meta-analyses. Two studies fulfilled all items of the methodological quality checklist. The overall prevalence of DH/toothache among patients with MIH was 45 %. Prevalence rates of 30 %, 47 %, and 55 % were estimated based on proxy reports, self-reports, and air stimulation, respectively. The overall prevalence of DH/toothache per tooth was 22 %, ranging from 16 % to 29 % according to the diagnostic method. Patients with MIH demonstrated higher likelihood of presenting proxy reports of DH/toothache compared to those without MIH (OR: 1.51, 95 % CI [1.23-1.85], P < 0.01, I2: 0 %). The certainty of evidence was very low, mainly due to the low methodological quality of included studies and high inconsistency. CONCLUSIONS: The global prevalence of DH/toothache was 22 %, per tooth, and 45 % per patient. Estimates vary according to diagnostic methods. Patients with MIH showed higher likelihood of presenting proxy reports of DH/toothache than controls. CLINICAL SIGNIFICANCE: This systematic review contributes valuable information to the dental literature by assessing the prevalence and associated factors of DH/toothache in patients with MIH. The findings can guide future research, inform clinical practices and public policy makers, and ultimately improve the management of oral health of patients with MIH.

A Review of the Ethnobotanical Use, Chemistry and Pharmacological Activities of Constituents Derived from the Plant Genus Geijera (Rutaceae).

Geijera Schott is a plant genus of the Rutaceae Juss. (rue and citrus) family, comprising six species which are all native to Oceania. Of the plants belonging to this genus, the most significant species that has a customary use is Geijera parviflora, which was used by Indigenous Australians, primarily as a pain reliever. Herein, a comprehensive review of the literature published on the genus Geijera from 1930 to 2023 was conducted. This is the first review for this plant genus, and it highlights the chemical constituents reported to date, together with the range of pharmacological properties described from the various species and different parts of the plant. These properties include anti-inflammatory, anti-microbial, anti-parasitic, insect repellent, analgesic, neuroactive, and anti-cancer activities. Finally, a reflection on some of the important areas for future focused studies of this plant genus is provided.

Evidence-based clinical practice guideline for the pharmacologic management of acute dental pain in adolescents, adults, and older adults: A report from the American Dental Association Science and Research Institute, the University of Pittsburgh, and the University of Pennsylvania.

BACKGROUND: A panel convened by the American Dental Association Science and Research Institute, the University of Pittsburgh, and the University of Pennsylvania conducted systematic reviews and meta-analyses and formulated evidence-based recommendations for the pharmacologic management of acute dental pain after simple and surgical tooth extraction(s) and for the temporary management (ie, definitive dental treatment not immediately available) of toothache associated with pulp and periapical diseases in adolescents, adults, and older adults. TYPES OF STUDIES REVIEWED: The panel conducted 4 systematic reviews to determine the effect of opioid and nonopioid analgesics, local anesthetics, corticosteroids, and topical anesthetics on acute dental pain. The panel used the Grading of Recommendations, Assessment, Development and Evaluation approach to assess the certainty of the evidence and the Grading of Recommendations, Assessment, Development and Evaluation Evidence-to-Decision Framework to formulate recommendations. RESULTS: The panel formulated recommendations and good practice statements using the best available evidence. There is a beneficial net balance favoring the use of nonopioid medications compared with opioid medications. In particular, nonsteroidal anti-inflammatory drugs alone or in combination with acetaminophen likely provide superior pain relief with a more favorable safety profile than opioids. CONCLUSIONS AND PRACTICAL IMPLICATIONS: Nonopioid medications are first-line therapy for managing acute dental pain after tooth extraction(s) and the temporary management of toothache. The use of opioids should be reserved for clinical situations when the first-line therapy is insufficient to reduce pain or there is contraindication of nonsteroidal anti-inflammatory drugs. Clinicians should avoid the routine use of just-in-case prescribing of opioids and should exert extreme caution when prescribing opioids to adolescents and young adults.

Barriers to Accessing Primary Dental Care in Adults with Alcohol Dependence: A Qualitative Study.

BACKGROUND: People with alcohol dependence (AD) frequently experience oral health problems, but their dental attendance is poor, with limited evidence to the reasons why from their perspective. OBJECTIVE: To explore perceived barriers, motivators, and facilitators to accessing primary dental care in people with AD. METHODS: Qualitative study consisting of remote one-to-one and group semistructured interviews with a convenience sample of adults with lived experience of AD in northern England. Data were audio-recorded, transcribed, and coded. A reflexive thematic analysis method was used; use of COM-B model informed data interpretation. RESULTS: Twenty adults with lived experience of AD participated in 18 one-to-one interviews and 1 group interview (of 3 participants). Barriers to access were fear and physical, social, and environmental factors (physical effects of AD, financial barriers, nonprioritization of oral health). Motivators to access were pain and prioritization of oral health. Facilitators to access were patterns of alcohol use (i.e., sobriety) and dental service provision within recovery services. CONCLUSIONS: Fear of "the dentist" is a major barrier to accessing dental care, and pain is the primary motivator, among people with AD, although neither are unique to this population. Fear and physical, social, and environmental barriers to access contribute to problem-oriented attendance, which negatively affect oral health outcomes. Opportunity to facilitate attendance increases when a person is in remission from AD through their physical capabilities improving. Increasing capability and opportunity can influence attendance beyond the automatic motivation of pain. Provision of dental care within recovery services could facilitate access to care. Understanding the "web of causation" is key to developing any intervention to improve dental access in people with AD. Further research is needed from the perspective of other adult populations with lived experience of AD, as well as of dental professionals, to gain deeper insight into barriers, facilitators, and possible solutions. KNOWLEDGE TRANSFER STATEMENT: The results of this study can help dental professionals understand factors affecting access to primary care in people with alcohol dependence to provide knowledge that may reduce stigma surrounding the disease. Results also demonstrate areas for intervention development for public policy.

Assessment of Preferences in Taking Painkillers among Students of Medicine, Dentistry, and Pharmacy: A Pilot Study.

Students of pharmacy, medicine, and dentistry are important for shaping drug policy. The aim of this study is to assess and compare students preferences in taking painkillers. The study group consists of 382 students of pharmacy (28.8%), medicine (40.0%), and dentistry (30.1%). An anonymous questionnaire consisting of 17 questions was prepared using the Google Forms platform and distributed through social media. Ibuprofen was the most frequently preferred, regardless of the study major (57.8%). Pharmacy students expressed the least concern about the possible side effects of analgesics (17.5%). The fast onset of painkillers was more important for dental students (59.1%) and pharmacy students (44.7%), compared to medical students (39.22%). Medicine and pharmacy students indicated their studies to be their main source of information about painkillers compared to dentistry students (p = 0.001). There are no differences in pain severity regarding which analgesics are used among student groups (p = 0.547). Dental students experienced odontogenic pain less frequently (57.3%) than medical (79.7%) and pharmacy students (79.8%), (p = 0.000). Ketoprofen was the most frequently chosen prescription painkiller for odontogenic pain in all groups (49.4%). Gastrointestinal complaints were the most often reported side effects, regardless of the study major (87.1%). Choice of studies, gender, and year of study were the most important determinants of the choice of painkillers.

Cannabidiol as an Alternative Analgesic for Acute Dental Pain.

Odontogenic pain can be debilitating, and nonopioid analgesic options are limited. This randomized placebo-controlled clinical trial aimed to assess the effectiveness and safety of cannabidiol (CBD) as an analgesic for patients with emergency acute dental pain. Sixty-one patients with moderate to severe toothache were randomized into 3 groups: CBD10 (CBD 10 mg/kg), CBD20 (CBD 20 mg/kg), and placebo. We administered a single dose of respective oral solution and monitored the subjects for 3 h. The primary outcome measure was the numerical pain differences using a visual analog scale (VAS) from baseline within and among the groups. Secondary outcome measures included ordinal pain intensity differences, the onset of significant pain relief, maximum pain relief, changes in bite force within and among the groups, psychoactive effects, mood changes, and other adverse events. Both CBD groups resulted in significant VAS pain reduction compared to their baseline and the placebo group, with a maximum median VAS pain reduction of 73% from baseline pain at the 180-min time point (P < 0.05). CBD20 experienced a faster onset of significant pain relief than CBD10 (15 versus 30 min after drug administration), and both groups reached maximum pain relief at 180-min. Number needed to treat was 3.1 for CBD10 and 2.4 for CBD20. Intragroup comparisons showed a significant increase in bite forces in both CBD groups (P < 0.05) but not in the placebo group (P > 0.05). CBD20 resulted in a significant difference in mean percent bite force change in the 90- and 180-min time points compared to the placebo group (P < 0.05). Compared to placebo, sedation, diarrhea, and abdominal pain were significantly associated with the CBD groups (P < 0.05). There were no other significant psychoactive or mood change effects. This randomized trial provides the first clinical evidence that oral CBD can be an effective and safe analgesic for dental pain.

Dental pain report in children and genetic polymorphism (rs4818) in Catechol-O-Methyltransferase (COMT) gene: a cross- sectional study

Abstract Aim: Polymorphisms in the COMT gene can alter enzymatic functions, raising levels of endogenous catecholamines, which stimulates beta-adrenergic receptors related to pain. This study aimed to evaluate whether a polymorphism in the COMT gene (rs4818) is associated with dental pain in children. Methodology: A cross-sectional study was conducted with a representative sample of 731 pairs of children and parents randomly selected from a population-based sample of eight-year-old children. Reports of dental pain was evaluated using a question directed at the parents and self-reported pain using the Faces Pain Scale - Revised. Dental caries experience was determined using the Decayed, Missing, and Filled Teeth (DMFT) index. For genetic analysis, DNA was obtained from oral mucosa epithelial cells of 352 children randomly selected from the initial sample. Results: Children with the CC genotype had higher odds of reporting moderate to intense pain than those with the GG genotype (OR=3.60; 95% CI=0.80-16.20; p=0.03). These same children had greater odds of parental reports of pain (OR=1.93; 95% CI=0.91-4.08; p=0.02). Moreover, lower schooling of parents/guardians and caries experience in the primary dentition were significantly associated with greater odds of a parental report of dental pain (OR=2.06; 95% CI=1.47-2.91; p<0.001; OR=6.26; 95% CI=4.46-8.78; p<0.001). Conclusions: The rs4818 polymorphism of the COMT gene is associated with dental pain. Children with the C allele are more likely to report higher levels of pain. Clinical Relevance: Even though the experience of pain is subjective and multifactorial, this study raises the hypothesis that there is a genetic predisposition to dental pain that should be considered in clinical practice.

Self-medication associated with toothache: a systematic literature review / Automedicação associada à dor de dente: uma revisão sistemática da literatura / Automedicación asociada al dolor de dientes: una revisión sistemática de la literatura

Introduction: Self-medication consists of selecting and using medication without a poprescription or guidance from a healthcare professional. This practice has been widely reported worldwide, which has contributed to a series of adverse health outcomes, such as delayed diagnosis, worsening of clinical conditions, drug interactions, intoxication, and adverse reactions, which tend to compromise patient safety. Objective:To analyze the prevalence of self-medication associated with toothache, the main factors associated with self-medication in dental patients, as well as outline the profile of medications used by these individuals, the preferred route of administration, and the main sources of medication.Methodology:Asystematic review was developed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Relevant articles published in the last ten years, without limitations of language were searched using the following descriptors/MeSHterms and keywords: "self-medication" and (toothache or "dental pain") not Child. Results:The initial search returned 61 manuscripts. Fourteen papers, all cross-sectional studies, were eligible for inclusion in the systematic review.Conclusions:The prevalence of self-medication for toothache ranged from 6.5% to 100.0%. Cultural and economic factors, barriers to access, the high cost of dental treatments, lack of time and money, and the perception that dental problems are not a serious problem are among the main factors associated with the practice. Regarding the drugs used, the most used classes were paracetamol, especially anti-inflammatory drugs, particularly ibuprofen, and analgesics administered orally (AU).

Advancements in Understanding and Classifying Chronic Orofacial Pain: Key Insights from Biopsychosocial Models and International Classifications (ICHD-3, ICD-11, ICOP).

In exploring chronic orofacial pain (COFP), this review highlights its global impact on life quality and critiques current diagnostic systems, including the ICD-11, ICOP, and ICHD-3, for their limitations in addressing COFP's complexity. Firstly, this study outlines the global burden of chronic pain and the importance of distinguishing between different pain types for effective treatment. It then delves into the specific challenges of diagnosing COFP, emphasizing the need for a more nuanced approach that incorporates the biopsychosocial model. This review critically examines existing classification systems, highlighting their limitations in fully capturing COFP's multifaceted nature. It advocates for the integration of these systems with the DSM-5's Somatic Symptom Disorder code, proposing a unified, multidisciplinary diagnostic approach. This recommendation aims to improve chronic pain coding standardization and acknowledge the complex interplay of biological, psychological, and social factors in COFP. In conclusion, here, we highlight the need for a comprehensive, universally applicable classification system for COFP. Such a system would enable accurate diagnosis, streamline treatment strategies, and enhance communication among healthcare professionals. This advancement holds potential for significant contributions to research and patient care in this challenging field, offering a broader perspective for scientists across disciplines.

Craniofacial Pain Management in Severe COVID-19 Patients During the Pandemic Peak in Kosovo: A Comprehensive Approach.

Background This cross-sectional study aims to evaluate pain management's success in limiting admissions and assesses remote care's effectiveness for optimal pain relief. By utilizing data from severe COVID-19 inpatients in Prishtina, Kosovo, this study offers insights into the challenges posed by the pandemic and innovative care approaches aimed at improving patient well-being. Methodology This cross-sectional study includes 55 patients with severe COVID-19 after hospital discharge. All study participants completed the questionnaire in the presence of a clinical pharmacologist. The questionnaire of this study consisted of three parts: sociodemographic data (first part), the Intensity and Characteristics of Toothache (IaCofT) and headache (second part), and pharmacological treatment of headache and dental pain (third part). The questionnaire on IaCofT and headache was created with some modifications of the Modified Dental Pain Screening Questionnaire (M-DePaQ). Descriptive statistics were conducted using Prism version 10.0.1 (Windows and Mac). Results According to the study data, 89.1% (n = 49) of the participants experienced pain during hospitalization with COVID-19, while 72.72% (n = 40) of them experienced pain after hospital discharge. Of the participants, 32.7% (n = 18) experienced dental pain, whereas 60% (n = 33) reported having headaches. Regarding the pain scale, more than two-thirds (n = 40, 72.72%) of the participants had moderate to moderately severe pain, and in 70.9% (n = 39) of the cases, the pain occurred episodically. The absolute majority (n = 53, 96.4%) of study participants reported the use of analgesics for pain management. Paracetamol (n = 46, 83.6%) and ibuprofen (n = 14, 25.5%) were the most commonly used analgesics for pain management. Conclusions This study highlighted the prevalence of headache and acute dental pain in these patients. The majority of the study participants were convinced by the healthcare system and were highly dependent on pharmacological treatment for headaches and acute toothache during the COVID-19 peak. The study results showed that the pain was proven to be successfully treated pharmacologically with analgesics such as paracetamol, ibuprofen, and diclofenac. Telemedicine is expected to become an important healthcare practice in the post-COVID-19 era. Therefore, the introduction of this service could be considered.

Evidence-based clinical practice guideline for the pharmacologic management of acute dental pain in children: A report from the American Dental Association Science and Research Institute, the University of Pittsburgh School of Dental Medicine, and the Center for Integrative Global Oral Health at the University of Pennsylvania.

BACKGROUND: A guideline panel convened by the American Dental Association Council on Scientific Affairs, American Dental Association Science and Research Institute, University of Pittsburgh School of Dental Medicine, and Center for Integrative Global Oral Health at the University of Pennsylvania conducted a systematic review and meta-analyses and formulated evidence-based recommendations for the pharmacologic management of acute dental pain after 1 or more simple and surgical tooth extractions and the temporary management of toothache (that is, when definitive dental treatment not immediately available) associated with pulp and furcation or periapical diseases in children (< 12 years). TYPES OF STUDIES REVIEWED: The authors conducted a systematic review to determine the effect of analgesics and corticosteroids in managing acute dental pain. They used the Grading of Recommendations Assessment, Development and Evaluation approach to assess the certainty of the evidence and the Grading of Recommendations Assessment, Development and Evaluation Evidence to Decision framework to formulate recommendations. RESULTS: The panel formulated 7 recommendations and 5 good practice statements across conditions. There is a small beneficial net balance favoring the use of nonsteroidal anti-inflammatory drugs alone or in combination with acetaminophen compared with not providing analgesic therapy. There is no available evidence regarding the effect of corticosteroids on acute pain after surgical tooth extractions in children. CONCLUSIONS AND PRACTICAL IMPLICATIONS: Nonopioid medications, specifically nonsteroidal anti-inflammatory drugs like ibuprofen and naproxen alone or in combination with acetaminophen, are recommended for managing acute dental pain after 1 or more tooth extractions (that is, simple and surgical) and the temporary management of toothache in children (conditional recommendation, very low certainty). According to the US Food and Drug Administration, the use of codeine and tramadol in children for managing acute pain is contraindicated.

Relationships among oral hygiene behavior, toothache, and depressive symptoms in Chinese older adults.

OBJECTIVES: The study aims to investigate the relationships among oral hygiene behavior, toothache, and depression among Chinese older adults. METHODS: We used data came from the 2018 wave of Chinese Longitudinal Healthy Longevity Survey (CLHLS). The Center for Epidemiologic Studies Depression Scale was used to evaluate depression. Binary logistic regression was performed to analyze the relationships among oral hygiene behavior, toothache, and depression. RESULTS: A total of 12,172 older adults were included in the study, of whom 27.2% had depression. Compared with those who did not brush their teeth daily, those who brushed their teeth at least once daily exhibited lower odds of having depressive symptoms (odds ratio [OR] = 0.86, 95% confidence interval [CI] = 0.77-0.97 versus OR = 0.81, 95% CI = 0.71-0.93). Compared with those who did not have toothache, those who had toothache over the past 6 months exhibited higher odds of having depression (OR = 1.49, 95% CI = 1.33-1.68). Living arrangement had a significant effect on the correlation between toothache and depression (p = 0.049), who lived alone and had toothache exhibited higher odds of having depressive symptoms. CONCLUSIONS: Oral hygiene behavior and toothache are associated with depression. Taking effective measures to maintain a daily toothbrushing pattern and reduce the occurrence of toothache may mitigate the risk of depression among older adults, especially among those living alone. CLINICAL RELEVANCE: The present study reports that the potential relationship between different oral hygiene behavior, toothache, and depressive symptoms.

Gerenciamento de urgências endodônticas: conhecimentos de acadêmicos de odontologia / Management of endodontic emergencies: knowledge of dental students

Objetivo: avaliar do conhecimento dos alunos de odontologia sobre os protocolos de atendimento para as urgências endodônticas. Método: 182 alunos dos últimos anos do curso de Odontologia do Centro Universitário Doutor Leão Sampaio, responderam a um questionário contendo perguntas referente ao protocolo adotado em casos de urgência de origem endodôntica. Os dados foram analisados pelo teste de Qui-quadrado de Pearson (p<0,05). Resultados: foram observadas diferenças entre a conduta relata pelos alunos do quarto e quinto ano de graduação quanto a indicação da incisão para drenagem em abscesso periapical agudo submucoso (evoluído), indicação de antibióticos nos casos de flare-up e indicação de antibióticos na dor com edema póstratamento endodôntico. A prescrição de antibióticos foi excessiva para os casos de dor entre consultas (flareup) e dor no pós-operatória. Para as patologias da polpa, a maioria dos alunos indicou protocolos de urgência recomendados na literatura. Conclusão: os resultados indicam a necessidade de melhoria dos programas de treinamento dos alunos em urgências endodônticas, principalmente quanto aos protocolos farmacológicos. (AU)

Objective: to evaluate the knowledge of dentistry students about care protocols for endodontic emergencies. Method: 182 students from the last years of the Dentistry course at Doctor Leão Sampaio University Center answered a questionnaire containing questions regarding the protocol adopted in urgent cases of endodontic origin. Data were analyzed using Pearson's Chi-square test (p<0.05). Results: differences were observed between the conduct reported by fourth- and fifth-year undergraduate students regarding the indication of incision for drainage in submucosal acute periapical abscess (evolved), indication of antibiotics in cases of flare-up and indication of antibiotics in pain with edema after endodontic treatment. The prescription of antibiotics was excessive for cases of pain between appointments (flare-up) and postoperative pain. For pulp pathologies, most students indicated emergency protocols recommended in the literature. Conclusion: the results indicate the need to improve student training programs in endodontic emergencies, especially regarding pharmacological protocols. (AU)

Assessing Google Searches for Toothache during COVID-19 Lockdowns.

Background: Lockdowns due to the coronavirus disease 2019 (COVID-19) pandemic forced many dental offices to be closed. This study aims to investigate the association between COVID-19 imposed lockdowns and online searches for toothache using Google Trends (GT). Methods: We investigated GT online searches for the term "toothache" within the past 5 years. The time frame for data gathering was considered as the initiation and end dates of national/regional lockdowns in each country. We used 1-way analysis of variance to identify statistical differences in relative search volumes (RSVs) between 2020 and 2016-2019 for each country. Results: Overall, 16 countries were included in our analyses. Among all countries, Indonesia (n = 100), Jamaica (n = 56), Philippines (n = 56), Iran (n = 52), and Turkey (47) had the highest RSVs for toothache in the specified period. Compared with the previous 4 years, higher RSVs were seen in the world (as a whole) (2020 RSVs, 94.4; vs 2019 RSVs, 77.8 [ P < 0.001]) and 13 countries (81.3% of the included countries). Conclusion: Generally, searching for the term "toothache" showed an increase during the COVID-19 lockdowns in 2020 compared with the past 4 years. This can imply the importance of dental care as urgent medical care during public health emergencies such as COVID-19.

Inclusion Complex of Ibuprofen-ß-Cyclodextrin Incorporated in Gel for Mucosal Delivery: Optimization Using an Experimental Design.

ß-Cyclodextrin/ibuprofen inclusion complex was synthesized by freeze-drying method and characterized for phase solubility profiles, infrared spectra, thermal analysis, and X-ray powder diffractograms. The inclusion complex with HP-ß-CD, as confirmed by molecular dynamics simulations, enhanced the aqueous solubility of ibuprofen by almost 30-fold compared to ibuprofen alone. Different grades of Carbopol (Carbopol 934P/Carbopol 974P/Carbopol 980 NF/Carbopol Ultrez 10 NF) and cellulose derivatives (HPMC K100M/HPMC K15M/HPMC K4M/HPMC E15LV/HPC) were evaluated for mucoadhesive gels incorporating the inclusion complex. The central composite design generated by Design-Expert was employed to optimize the mucoadhesive gel using two independent variables (a varying combination of two gelling agents) on three dependent variables (drug content and in vitro drug release at 6 h and 12 h). Except for the methylcellulose-based gels, most of the gels (0.5%, 0.75%, and 1% alone or as a mixture thereof) exhibited an extended-release of ibuprofen, ranging from 40 to 74% over 24 h and followed the Korsmeyer-Peppas kinetics model. Using this test design, 0.95% Carbopol 934P and 0.55% HPC-L formulations were optimized to increase ibuprofen release, enhance mucoadhesion, and be non-irritating in ex vivo chorioallantoic membrane studies. The present study successfully developed a mucoadhesive gel containing the ibuprofen-ß-cyclodextrin inclusion complex with sustained release.

Analgesics for the management of acute dental pain in the pediatric population: A systematic review and meta-analysis.

BACKGROUND: The authors assessed the clinical effectiveness of analgesics to manage acute pain after dental extractions and pain associated with irreversible pulpitis in children. TYPES OF STUDIES REVIEWED: The authors searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and US Clinical Trials registry from inception through November 2020. They included randomized controlled trials comparing any pharmacologic interventions with each other and a placebo in pediatric participants undergoing dental extractions or experiencing irreversible pulpitis. After duplicate screening and data abstraction, the authors conducted random-effects meta-analyses. They assessed risk of bias using the Cochrane Risk of Bias 2.0 tool and certainty of the evidence using the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS: The authors included 6 randomized controlled trials reporting 8 comparisons. Ibuprofen may reduce pain intensity compared with acetaminophen (mean difference [MD], 0.27 points; 95% CI, -0.13 to 0.68; low certainty) and a placebo (MD, -0.19 points; 95% CI, -0.58 to 0.21; low certainty). Acetaminophen may reduce pain intensity compared with a placebo (MD, -0.13 points; 95% CI, -0.52 to 0.26; low certainty). Acetaminophen and ibuprofen combined probably reduce pain intensity compared with acetaminophen alone (MD, -0.75 points; 95% CI, -1.22 to -0.27; moderate certainty) and ibuprofen alone (MD, -0.01 points; 95% CI, -0.53 to 0.51; moderate certainty). There was very low certainty evidence regarding adverse effects. PRACTICAL IMPLICATIONS: Several pharmacologic interventions alone or in combination may provide a beneficial effect when managing acute dental pain in children. There is a paucity of evidence regarding the use of analgesics to manage irreversible pulpitis.

Acupuncture in management of acute dental pain - A systematic review and meta-analysis.

Acute dental pain is a common issue leading to dental consultation. Besides causal therapy, patients are treated with acupuncture, but efficacy in acute dental pain is still not clarified. We aimed to evaluate results of recent research to estimate the efficacy of acupuncture compared to pain-relieving approaches in treatment of acute dental pain. A systematic review of controlled trials being published between database inception and 2020 were conducted to evaluate the efficacy of acupuncture (alone or as complementary therapy) compared to local anesthesia or conventional analgesic medications in acute dental pain (intraoperatively and postoperatively) and to clarify whether acupuncture reduces the use of postoperative analgesic medications. Of 1672 publications, 23 publications met the inclusion criteria. From these, 11 randomized controlled trials (n = 668) reported on the efficacy of acupuncture on postoperative acute dental pain. Patients, who received acupuncture, showed lower pain scores postoperatively compared to sham acupuncture (Relative Risk -0.77, 95% Confidence interval -1.52 to -0.03). Overall, the results suggest a potential role of acupuncture in improving acute dental pain intraoperatively and postoperatively as well as improving the efficacy of local anesthesia, but the results are limited due to methodological shortcomings emphasizing the necessity for future high-quality research.

The association between poor oral health and risk of breast cancer in the UK Biobank.

PURPOSE: Specific oral health conditions may be risk factors for breast cancer. This study aimed to investigate the associations of oral health conditions with breast cancer risk. METHODS: A total of 234,363 women from the UK Biobank prospective cohort were included in this study. We examined the association of self-reported painful/bleeding gums, loose teeth, mouth ulcers, toothache, and use of dentures with the risk of breast cancer. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) for the associations were calculated with adjustment for multiple confounders. RESULTS: No associations of self-reported painful/bleeding gums (HR = 1.04, 95% CI 0.98-1.10), loose teeth (HR = 0.92, 95% CI 0.82-1.02), mouth ulcers (HR = 0.99, 95% CI 0.93-1.06), toothache (HR = 1.03, 95% CI 0.92-1.14), or denture use (HR = 0.96, 95% CI 0.91-1.02) with breast cancer risk were found. No statistical heterogeneity was observed in analyses stratified by baseline smoking and menopausal status. CONCLUSION: We observed no association between self-reported oral health conditions with the risk of breast cancer. Additional research with clinical examinations or oral health biomarkers in diverse populations is warranted.
