Do Third Molars Contribute to Systemic Inflammation? Results From a Population-Based Study From Northeast Germany

Salivary Levels of Malondialdehyde and Total Antioxidant Capacity Following Third Molar Surgery - An Evaluative Study

Introduction

Impacted and semi-impacted third molar surgery can lead to considerable distress and discomfort in patients.

Aims

The present study aimed to assess the changes in salivary levels of malondialdehyde (MDA) and total antioxidant capacity (TAC) after third molar surgery.

Materials and Methods

In this study, 210 patients scheduled for third molar surgery were selected. Unstimulated whole saliva samples were collected from patients preoperatively and one week after the surgery, via the 'spitting method'. The collected samples were immediately centrifuged and the supernatants were stored at -20°C until testing. The levels of MDA and TAC were measured with a spectrophotometer.

Results

The results were presented as mean ± standard deviation and paired t-test was used to statistically analyse the changes in pre-operative and post-operative values of MDA and TAC. A decrease of mean salivary TAC (P = 0.031) and an increase of mean salivary MDA (P = 0.034) were detected postoperatively.

Discussion

Following third molar surgery, the increase of mean salivary MDA and the decrease of mean salivary TAC were detected; however, these changes were not statistically significant.

C-Reactive Protein: Pathophysiology, Diagnosis, False Test Results and a Novel Diagnostic Algorithm for Clinicians

The current literature provides a body of evidence on C-Reactive Protein (CRP) and its potential role in inflammation. However, most pieces of evidence are sparse and controversial. This critical state-of-the-art monography provides all the crucial data on the potential biochemical properties of the protein, along with further evidence on its potential pathobiology, both for its pentameric and monomeric forms, including information for its ligands as well as the possible function of autoantibodies against the protein. Furthermore, the current evidence on its potential utility as a biomarker of various diseases is presented, of all cardiovascular, respiratory, hepatobiliary, gastrointestinal, pancreatic, renal, gynecological, andrological, dental, oral, otorhinolaryngological, ophthalmological, dermatological, musculoskeletal, neurological, mental, splenic, thyroid conditions, as well as infections, autoimmune-supposed conditions and neoplasms, including other possible factors that have been linked with elevated concentrations of that protein. Moreover, data on molecular diagnostics on CRP are discussed, and possible etiologies of false test results are highlighted. Additionally, this review evaluates all current pieces of evidence on CRP and systemic inflammation, and highlights future goals. Finally, a novel diagnostic algorithm to carefully assess the CRP level for a precise diagnosis of a medical condition is illustrated.

SHIP-MR and Radiology: 12 Years of Whole-Body Magnetic Resonance Imaging in a Single Center

The Study of Health in Pomerania (SHIP), a population-based study from a rural state in northeastern Germany with a relatively poor life expectancy, supplemented its comprehensive examination program in 2008 with whole-body MR imaging at 1.5 T (SHIP-MR). We reviewed more than 100 publications that used the SHIP-MR data and analyzed which sequences already produced fruitful scientific outputs and which manuscripts have been referenced frequently. Upon reviewing the publications about imaging sequences, those that used T1-weighted structured imaging of the brain and a gradient-echo sequence for R2* mapping obtained the highest scientific output; regarding specific body parts examined, most scientific publications focused on MR sequences involving the brain and the (upper) abdomen. We conclude that population-based MR imaging in cohort studies should define more precise goals when allocating imaging time. In addition, quality control measures might include recording the number and impact of published work, preferably on a bi-annual basis and starting 2 years after initiation of the study. Structured teaching courses may enhance the desired output in areas that appear underrepresented.

Are third molars associated with orofacial pain? Findings from the SHIP study

OBJECTIVES

To examine the association between third molars and orofacial pain. We hypothesized that impacted third molars are a cause of orofacial pain.

METHODS

Magnetic resonance images of 1808 participants from two population-based cohorts from Northeastern Germany were analysed to define the status of third molars according to the Pell and Gregory classification. A self-reported questionnaire and a clinical dental examination were used to detect chronic and acute complaints of orofacial pain, masticatory muscle pain, migraine and other types of headache. Logistic regression models were used to analyse the associations between third molar status and orofacial pain.

RESULTS

Individuals with impacted third molars in the maxilla had a higher chance of chronic orofacial pain than those with erupted third molars (odds ratio 2.19; 95% CI 1.19-4.02). No such association was detected for third molars in the lower jaw. Third molars were not associated with masticatory muscle pain, migraine or other types of headache.

CONCLUSIONS

Impacted maxillary third molars might be a cause of chronic orofacial pain. Thus, physicians should consider the eruption/impaction status of third molars in their decision-making process when treating patients who complain of orofacial pain.

Postoperative pain, edema and trismus following third molar surgery - A comparitive study between submucosal and intravenous dexamethasone

BACKGROUND

Third molar surgey always needs primary intervention as it can lead to various complications and pathologies. Considering other ways for postoperative anesthesia it was infered that submucosal group which showed simple injection technique and direct surgical site administration is more beneficial. It was noticed as a patient comfort method which can be the preferred as the drug of choice over intravenous route of dexamethasone injection.

INTRODUCTION

Impaction of third molar is a common affliction and surgical removal is the only treatment option. The post-operative sequelae following the third molar surgery are pain, edema and trismus. The use of corticosteroids is to counteract it via various routes. Still, controversy exists in the literature regarding the administration of corticosteroids over the routes and time of administration. The purpose of this study was to compare the postoperative pain, edema and trismus following third molar surgery while using preoperative intravenous and submucosal routes of dexamethasone, in terms of pain, facial swelling, and trismus.

MATERIALS AND METHODS

This study consisted of 64 patients presented with mesioangular impacted mandibular third molar for surgical removal. Preoperative measurements of edema, trismus were analyzed. Postoperative pain was estimated using visual analogue scale. Edema was assessed by the extra oral facial measurements. Trismus was measured by recording the interincisal opening in millimeters. Dexamethasone was administered intravenously or submucosally according to the choice of operating surgeon and were divided into 2 groups.

RESULTS

Mean and standard deviation calculated for continuous variables. Changes in parameters was analysed using t test and Mann-Whitney U test. Here, submucosal group were reported with increased pain on the second postoperative day. On seventh postoperative day mean value turns to 0.7 ± 1 for submucosal and 0.6 ± 1.2 for intravenous group. On overall observation, intravenous group expressed statistically significant (P < 0.01) reduction in pain compared to the submucosal group during immediate and second postoperative days.

CONCLUSION

Analyzing the previous studies, and from the experience of the present one, it could be reasonably found out that administration of submucosal dexamethasone is beneficial for overall patient compliance.
