Manual toothbrushes, self-toothbrushing, and replacement duration to remove dental plaque and improve gingival health: A scoping review from recent research. J Dent 2024; 148:105240. [PMID: 39038528 DOI: 10.1016/j.jdent.2024.105240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 07/04/2024] [Accepted: 07/12/2024] [Indexed: 07/24/2024] Open
Abstract
OBJECTIVE To investigate characteristics of manual toothbrushes, self-toothbrushing methods, and replacement duration of manual toothbrushes that effectively remove dental plaque, reduce gingivitis, and promote gingival health. STUDY DATA AND SOURCES PubMed-MEDLINE, Scopus and Central Register Cochrane of Controlled trials (CENTRAL) were searched for randomized control trials (RCTs) from 01 January 2018 to 12 December 2023. Articles were subjected for including participants aged six years and older with a study duration of at least four weeks to investigate the efficacy of manual toothbrushes used self-toothbrushing. To investigate the appropriate time to replace manual toothbrushes, this study was focused on the physical properties of the bristles and changes in the microorganisms present in the bristles over time. STUDY SELECTION Of 1520 retrieved articles, 26 studies were included after screening. The total number of manual toothbrushes was 40 and 5 kinds of self-toothbrushing techniques were selected in the review. 4 studies investigated the changes the physical properties bristles of manual toothbrushes. CONCLUSIONS Among manual toothbrushes, the cross-angle and indicator bristles were found to significantly improve dental plaque index and gingival condition. Most toothbrushes with soft bristles had a trend of superior dental plaque removal and gingivitis improvement efficacy. Toothbrush with end-round shape bristles tip has tended to reduce the dental plaque and gingival index scores. Studies reported that brushing twice a day for at least two minutes using the Bass method had a positive effect on the dental plaque and gingival index. Further research is required to investigate the relationships between property physical bristle and clinical intraoral indices to clarify the replacement duration of manual toothbrushes. CLINICAL SIGNIFICANCE The findings of this study could guide people's daily self-brushing habits, thereby aiding the prevention of periodontal disease. Moreover, our findings suggest the need for strategic clinical trial designs to verify the ideal timing to replace manual toothbrushes.

Zhen YY, Yang J, Liao PY. Human herpesvirus 7 meningitis in an adolescent with normal immune function: A case report. World J Clin Cases 2024; 12:3636-3643. [PMID: 38983391 PMCID: PMC11229909 DOI: 10.12998/wjcc.v12.i18.3636] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2024] [Revised: 04/21/2024] [Accepted: 05/07/2024] [Indexed: 06/13/2024] Open
Abstract
BACKGROUND Human herpesvirus type 7 (HHV-7) is a less common herpes virus that usually causes mild, self-limiting illnesses. However, in recent years, there have been increasing reports of HHV-7 causing serious central nervous system infections, especially meningitis. The pathogenesis and clinical features of HHV-7 meningitis, particularly in adolescents with normal immune function, remain incompletely studied. Therefore, the purpose of this report is to share a case of HHV-7 meningitis in an immunocompetent adolescent with a view to deepening our understanding of the disease. CASE SUMMARY A 12-year-old female was admitted with fever, headache, and vomiting. 4 d before admission, the patient developed a fever without obvious induction, with a temperature up to 39.5 °C, no convulsions, accompanied by chills, headaches, fatigue, and no muscle aches. The patient was treated with fever reduction, which could be reduced to 38 °C; repeated high fever, accompanied by vomiting 7-8 times; and no abdominal pain or diarrhea. The patient was diagnosed with "acute suppurative tonsillitis" in a local hospital, and the blood routine was generally normal. The patient was given symptomatic support treatment such as "ceftriaxone sodium" and antiemetic rehydration for 2 d, and his condition did not improve. The patient's physical examination showed pharyngeal congestion, bilateral tonsil grade I hypertrophy, regression of purulent secretions, and cervical resistance. Ocular B-ultrasound: Opacity of the vitreous body and edema of the optic disc in both eyes. Optical coherence tomography examination showed that the macular fovea was generally normal in both eyes, with edema of the optic disc. DNA virus monitoring results: HHV-7. We gave ganciclovir antiviral therapy, dexamethasone anti-inflammatory treatment, mannitol to reduce cranial pressure, omeprazole to protect gastrointestinal mucosa, and calcium and potassium supplementation. CONCLUSION This study reports a case of HHV-7 meningitis in an adolescent with normal immune function. Through comprehensive analysis of the clinical manifestations, laboratory tests, and treatment methods of the patient, it is found that early identification and antiviral treatment are essential for the outcome of the disease. This case suggests that despite normal immune function, adolescents may still suffer from herpes virus type 7 meningitis, so clinicians should be vigilant and take effective treatment measures in time.

Shigeishi H, Hamada N, Kaneyasu Y, Niitani Y, Takemoto T, Ohta K. Prevalence of oral Capnocytophaga species and their association with dental plaque accumulation and periodontal inflammation in middle‑aged and older people. Biomed Rep 2024; 20:99. [PMID: 38765863 PMCID: PMC11099601 DOI: 10.3892/br.2024.1787] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2024] [Accepted: 03/29/2024] [Indexed: 05/22/2024] Open
Abstract
Capnocytophaga species are commonly found in human oral microbiome. The aim of the present study was to understand the association of the prevalence of oral Capnocytophaga species with oral hygiene and periodontal inflammation. A total of 136 patients (median age 72 years) who visited the Hiroshima University Hospital (Hiroshima, Japan) between April 2021 and June 2023 were enrolled. Swab samples were obtained from the tongue surface. DNA from Capnocytophaga species (C. ochracea and C. sputigena) was detected by real-time PCR analysis. Dental plaque accumulation was observed to assess the oral hygiene condition of participants. Additionally, clinical periodontal inflammation was assessed with periodontal inflamed surface area (PISA) scores. Clinical confounding factors such as age, sex, lifestyle-related disease, remaining teeth and denture wearing between Capnocytophaga species-positive and -negative groups were adjusted with a propensity score matching method. Mann-Whitney U and χ2 or Fisher's exact test were employed for statistical analysis. The prevalence rate was 67.6% for oral C. ochracea and 83.1% for C. sputigena. C. ochracea-positive participants showed significantly higher plaque control record scores (an indicator of dental plaque accumulation) than C. ochracea-negative participants (P=0.03). Additionally, C. ochracea/C. sputigena dual-positive participants exhibited significantly higher plaque control record and PISA scores than non-dual-positive participants (P=0.01 and P=0.04, respectively). Propensity score matching was conducted in the C. ochracea/C. sputigena dual-positive group and the non-dual-positive group for adjustment of clinical factors, resulting in 51 matched patient pairs. C. ochracea/C. sputigena dual-positive participants had significantly higher plaque control record scores than non-dual-positive participants (P=0.02). The present results suggest that the prevalence of both oral C. ochracea and C. sputigena is associated with poor oral hygiene in middle-aged and older people.

Abstract
OBJECTIVE The objective of this study was to clarify the association between preoperative periodontitis and postoperative systemic inflammation in patients with gastric cancer. SUBJECTS AND METHODS This retrospective cohort study analyzed data from 140 gastric cancer patients who underwent surgery at Hiroshima University Hospital between May 2019 and May 2022. Periodontal inflamed surface area (PISA) scores were determined to assess periodontitis severity using modified Nesse's methods. Propensity score matching was used to compare patients with high and low PISA scores (> or < the median PISA score of 92.4, respectively). Propensity scores were calculated using a logistic regression model, based on 17 clinical parameters: age, sex, smoking, alcohol consumption, hypertension, diabetes, dyslipidemia, cardiovascular disease, stroke, clinical stage, surgical procedure, surgical approach, neoadjuvant chemotherapy, surgery duration, blood loss during surgery, remaining teeth, and denture use. RESULTS Thirty-seven patients were propensity-score-matched. Participants with high PISA scores had a higher incidence of surgical site infection (10.5%) than those with low PISA scores (5.3%). Moreover, participants with high PISA scores had significantly higher C-reactive protein levels on postoperative days 1 than those with low PISA scores. CONCLUSION Preoperative periodontitis may determine the level of postoperative systemic inflammation in patients with gastric cancer.

Detection of Human Herpesviruses in Sera and Saliva of Asymptomatic HIV-Infected Individuals Using Multiplex RT-PCR DNA Microarray. Pathogens 2023; 12:993. [PMID: 37623953 PMCID: PMC10457847 DOI: 10.3390/pathogens12080993] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Revised: 07/19/2023] [Accepted: 07/26/2023] [Indexed: 08/26/2023] Open
Abstract
Human herpesviruses (HHVs) are frequently linked to an increased risk of acquiring human immunodeficiency virus (HIV), and vice versa. This study aimed to detect human herpesvirus (HHV) members in the sera and saliva of asymptomatic HIV-infected individuals. Paired saliva and serum samples were obtained from 30 asymptomatic HIV-infected individuals. HHVs were detected with a multiplex reverse transcription-polymerase chain reaction (RT-PCR) DNA microarray Clart®Entherpex kit. A total of 30 subjects were enrolled: 23 (76.67%) men and 7 (23.33%) women. The present study showed that at least one or more HHV members were detected in the saliva and sera of all (100%) of the subjects. In the saliva, we detected herpes simplex virus 1 (HSV-1) 6.67%, herpes simplex virus 2 (HSV-2) 6.67%, Epstein-Barr virus (EBV) 86.67%, cytomegalovirus (CMV) 63.33%, HHV-6 (40%), and HHV-7 (83.33%). In the sera, HSV-2 (20%), EBV (30%), CMV (40%), HHV-6 (0%), and HHV-7 (76.67%) were found, but not HSV-1. VZV and HHV-8 were not detected in either the saliva or sera. EBV and HHV6 were significantly more prevalent in the saliva than they were in the sera of asymptomatic HIV-infected individuals (p < 0.05). However, no significant differences were found in the prevalence of HSV-1, EBV, CMV, HHV-6, and HHV-7 in the saliva and sera of asymptomatic HIV-infected individuals (p > 0.05). In conclusion, the multiplex RT-PCR DNA microarray can serve as a valuable diagnostic tool that can be used as a screening tool or a first-line test for HHVs infections.

Exploring the Relationship between Periodontitis, Anti-Periodontitis Therapy, and Extra-Oral Cancer Risk: Findings from a Nationwide Population-Based Study. Biomedicines 2023; 11:1949. [PMID: 37509588 PMCID: PMC10377021 DOI: 10.3390/biomedicines11071949] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2023] [Revised: 07/05/2023] [Accepted: 07/06/2023] [Indexed: 07/30/2023] Open
Abstract
This study aimed to evaluate the systemic impact of periodontitis, previously considered a local disease, on cancer occurrence. We enrolled 683,854 participants, comparing cancer incidence among those with and without periodontitis and assessing the impact of periodontal treatment on cancer risk. Regardless of gender, age, Charlson comorbidity index, or the use of non-steroidal anti-inflammatory drugs, periodontitis patients had a lower overall cancer risk than controls. However, men with periodontitis had a higher risk of prostate cancer (adjusted hazard ratio [aHR] = 1.22; 95% confidence interval [CI] = 1.10-1.35), and both men and women had a higher risk of thyroid cancer (women: aHR = 1.20, 95%CI = 1.04-1.38; men: aHR = 1.51, 95% CI = 1.15-1.99). Patients with periodontitis who received treatment showed a reduced cancer risk (aHR = 0.41; 95% CI = 0.38-0.44) compared to untreated patients. Proper treatment for periodontitis may lower an individual's cancer risk more than if they did not have the disease at all, suggesting that periodontitis is a modifiable risk factor for cancer.
