Applicability of an active matrix metalloproteinase-8 point-of-care test in an oral and maxillofacial surgery clinic: a pilot study

OBJECTIVES

Matrix metalloproteinases are enzymes that participate in numerous inflammatory responses and have been targeted as biomarkers in numerous pathologic states. The detection of active matrix metalloproteinase-8 (aMMP-8) using a mouthrinse point-of-care test (POCT) has emerged as a diagnostic marker for periodontitis and other systemic inflammatory states. The objective of this pilot study was to assess the applicability of aMMP-8 POCT in an oral and maxillofacial surgery clinic and to evaluate the relationship between aMMP-8 levels and different patient groups.

MATERIALS AND METHODS

aMMP-8 POCT samples were collected from patients in an oral and maxillofacial surgery clinic during a one-month period. aMMP-8 levels were analyzed using a chairside lateral-flow immunotest and a digital reader. Clinically relevant patient variables were collected and descriptively evaluated. aMMP-8 levels over 20 ng/ml were considered to be elevated.

RESULTS

A total of 115 patients were interviewed of which 112 agreed to the test (97.4%). Elevated aMMP-8 levels were observed in 58 (51.8%) patients. Bone loss was noted in 75 (67.0%) patients. Of these patients, aMMP-8 levels were elevated in 47 (62.7%) patients. Patients at an increased risk of infection had 35.5% higher aMMP-8 values on average compared to patients with no prior illnesses.

CONCLUSION

aMMP-8 POCT provides a non-invasive and reliable method for measuring aMMP-8 levels. Future studies are warranted to assess the clinical relevance between elevated aMMP-8 levels and specific patient groups.

CLINICAL RELEVANCE

The rapid availability of the test score allows an immediate impact on treatment planning.

Knowledge of handling medical emergencies among general dental practitioners pan India: a cross-sectional survery

BACKGROUND

Medical emergency situations in dental clinics have been contemplated to be an issue in most of the countries by reason of dentist's lack of knowledge and preparedness to attend emergency situations in dental offices. The aim of this paper is to observe the knowledge, attitude, and perceived confidence of the general dental practitioners regarding emergency medical care and its practical application. Questionnaire on knowledge assessment was circulated among 500 dentists using printed questionnaire formats and various social media platforms. The questionnaire included details on treating hypertensive patients, cardiopulmonary resuscitation training, accessibility of medical emergency equipments in the dental clinics, prevalence of medical emergency cases in the dental office and the self-assessed competence to handle medical emergency situations in the dental clinics. Data was surveyed and scrutinized using the Statistical Package for Social Sciences (SPSS), version 17 (SPSS Inc., Chicago IL). Descriptive statistics was tabulated and Chi square tests was applied.

FINDINGS

500 general dental practitioners pan India were involved in the study (294 were females and 207 were males). They were grouped into different age groups (20-30 yrs, 30-40 yrs, 40-50 yrs, 50 and above) and experience (0-5 yrs, 5-10 yrs and more than 10 years). 279 participants did not attend any medical emergency training whereas, 222 participants from all groups attended training program. It was observed that with increased experience in the field, the knowledge, awareness and confidence to treat medical emergency situation in the dental clinics was better. Dentists should update themselves from time-to-time with the latest technologies in the field and need to attend training programs to handle any medical emergency situations in the dental offices. Medical emergencies in a dental clinic can be encountered at any point of time and the clinician should have apt knowledge in handling such situations. Majority of the dentists feel subdued in managing medical situations in dental offices. Training and workshops for handling medical situations in the dental offices should be mandated at the undergraduate and postgraduate levels. This will help the dentist to shape one's confidence in managing such situations without apprehension. Availability of proper infrastructure and equipments is recommended in every dental clinics so as to ease the handling of the situation.

CONCLUSION

This paper enlightens the need of basic life support training on regular basis among the dentists to improve the competence among them and to improve the confidence in handling such situations.

The COVID-19 pandemic and its possible impact on the treatment of odontogenic and intraoral abscesses

Most odontogenic and intraoral abscesses can be treated on an outpatient basis with local anesthesia. However, severe disease progression may require an incision under general anesthesia (GA) with postoperative inpatient treatment. This study aimed to evaluate the first "COVID-19 year" in Germany and compare the first "COVID-19 year" with the two previous years. All consecutive cases with odontogenic or intraoral abscesses treated in an outpatient or inpatient setting between 2018 and 2021 were included in this study. Data were collected, including the type of anesthesia, length of hospital stay, and healthcare costs. Despite the lower total number of abscess treatments in the first year of COVID-19 (n = 298 patients) than that in the two previous years (n = 663 patients), the number of advanced abscesses requiring intervention under GA was significantly higher (p < 0.001). This increased burden of care was also reflected in increased healthcare costs. The measures taken against the COVID-19 pandemic had an impact on the course of other diseases, for example, odontogenic and intraoral abscesses. The results showed an emerging conflict in patient care during the pandemic crisis that should be considered in possible future pandemics.

Antibiotics Efficiency in the Infection Complications Prevention after Third Molar Extraction: A Systematic Review

(1) Background: Antibiotics are used in every medical field including dentistry, where they are used for the prevention of postoperative complications in routine clinical practice during the third molar extraction. (2) Methods: This study is reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The present systematic review aimed to evaluate and systematize the use of antibacterial drugs in order to prevent postoperative complications in outpatient oral surgery for wisdom teeth extraction. We conducted a systematic review using electronic databases such as Medline PubMed, Scopus, and the Cochrane Central Register of Controlled Trials. Considering inclusion and exclusion criteria, we included randomized clinical trials published up to 2021 investigating the antibiotic prescription for third molar extraction. (3) Results: We selected 10 studies after the application of inclusion and exclusion criteria. The results showed that the most widely used antibiotic was amoxicillin both with and without clavulanic acid, in different dosages and duration. There were no statistically significant differences between treatment groups for development of postoperative complications. (4) Conclusions: Based on the analysis of the included studies, penicillin is currently the most widely prescribed group of antibiotics. The widespread use of this antibiotic group can lead to antimicrobial resistance (AMR). Due to increasing prevalence of bacteria resistance to penicillins, clinicians should carefully prescribe these antibiotics and be aware that the widespread use of amoxicillin may do more harm than good for the population.

Subinhibitory Antibiotic Concentrations Enhance Biofilm Formation of Clinical Enterococcus faecalis Isolates

Enterococcus faecalis is a microorganism that can be found in the oral cavity, especially in secondary endodontic infections, with a prevalence ranging from 24-70%. The increase in the ability to form biofilms in the presence of subinhibitory antibiotic concentrations is a phenomenon that is observed for a wide variety of bacterial pathogens and is associated with increased resistance. In this study, therefore, six E. faecalis isolates from an endodontic environment and two control strains were exposed to subinhibitory concentrations of Penicillin G, Amoxicillin, Doxycycline, Fosfomycin, Tetracycline and Vancomycin and examined for their biofilm formation abilities. The minimum inhibitory concentration (MIC) was determined for all E. faecalis isolates. A culture of the isolate was mixed with a serial dilution series of the respective antibiotic, incubated overnight and the biofilm formation was analyzed using a microtiter plate assay. All isolates were able to form biofilms in the absence of an antibiotic. A significant increase in biofilm formation of up to more than 50% was found in the isolates exposed to subinhibitory concentrations of various antibiotics. Most isolates showed a significant increase in Fosfomycin (7/8), Doxycycline (6/8) and Tetracycline (6/8). Three endodontic isolates showed a significant increase in five of the antibiotics examined at the same time. On exposure to Vancomycin, three endodontic isolates and the two control strains showed an increase. The increase in the ability to form biofilms extended over a concentration range from 1/2 to 1/64 of the MIC concentration. Antibiotics may reach certain niches in the oral cavity at subinhibitory concentrations only. This can increase the biofilm formation by enterococci, and in turn lead to decreased susceptibility of these taxa to antibiotics.

Root canal microorganisms and their antibiotic susceptibility in patients with persistent endodontic infections, with and without clinical symptoms

Secondary/persistent infections are present in teeth with previous root canal treatment, and a great variety of anaerobic microorganisms has been observed in these infections. The antibiotics prescription is occasional; however, in some cases, it is essential, particularly when the general health condition of the patient is compromised. The aims of this study were to identify the associated microorganisms in diagnosis of persistent or secondary apical periodontitis and to evaluate the susceptibility level to the antibiotics most used. Fifteen patients with persistent or secondary apical periodontitis requiring endodontic re-treatment were included. Microbiological samples were taken from the root canals and incubated in thioglycollate under anaerobic conditions. Anaerobic CDC agar (formulated by the Center for Disease Control and Prevention) was employed as a culture medium and the microorganisms were identified using the API system. The microorganisms were subjected to antibiograms with three different antibiotics. Twenty-six microorganisms were identified, the most common genus was Enterococcus (26.8%), Streptococcus (19.22%), Aerococcus (19.1%), and Clostridium (11.4%). 48% of them were susceptible to amoxicillin, with 28% of resistance. For clavulanic acid/amoxicillin, the susceptibility occurred in 32%, with 28% of resistance; and for clindamycin, the susceptibility was present in 40%, with 52% of resistance. The most frequently detected associated microorganism for secondary infections was genus Enterococcus, which exhibited high resistance to the studied antibiotics.

Assessment of routine diet (garlic consumption) as a pre- and postoperative protocol in oral and maxillofacial surgical interventions: An evidence-based literature review

BACKGROUND

It was hypothesized that pathological bleeding (PB) during and/or after oral surgical procedures is higher in systemically healthy patients who have a history of garlic intake compared to controls (patients without a history of garlic consumption).

AIM

The aim of the present review article was to identify studies in which garlic consumption was included as a patient management protocol before and after oral and maxillofacial surgery (OMFS).

METHODS

A review of pertinent indexed literature was performed. The focused question that was addressed was "Has diet (garlic consumption) been considered as a patient management protocol before and after OMFS?" The inclusion criteria were: (a) studies published in indexed databases, (b) original studies, (c) studies on OMFS, and (d) studies that considered diet (garlic consumption) as a patient management protocol before and after OMFS. Literature review, commentaries, letters to the editor, and studies published in non-indexed resources were excluded. The pattern of the present review was customized to summarize the pertinent information.

RESULTS

The initial search using the terms "oral," maxillofacial," "protocol," and "surgery" yielded 1478 studies. The addition of the term "diet" to this search strategy reduced the number of studies to five. Further filtration of these studies using the terms "garlic" and/or "Allium sativum" showed no studies.

CONCLUSIONS

Garlic intake predisposes patients to PB. However, there are no studies in the indexed literature that have considered the inclusion of garlic consumption in patient management protocols before and after OMFS.
