Revisiting the Risk Factors for Multiple Symptoms of Temporomandibular Disorders: A structured Cross-sectional Study

Background: The risk factors for Temporomandibular Disorders (TMD) are extensively studied, but the results showed no consistency. Only a small proportion of patients with TMD are likely to seek help and require treatment. Those individuals tend to present with multiple symptoms. This cohort of patients was not well investigated. Objective: The study aimed to examine the association between possible risk factors for presentation with multiple TMD symptoms. Methods: A population-based, cross-sectional study was conducted across 2101 individuals with an age range of 19-60 years. The condition was assessed via a detailed questionnaire comprising symptoms, habits, dental history, general health, sleep patterns, along with the completion of the Hospital Anxiety and Depression (HAD) scale, followed by an examination of the hypothesized clinical signs. The obtained data were tabulated and characterized the study population in a descriptive analysis in forms of percentages and frequencies. The significance level was set at P-value less than or equal to 0.005. The chi-squared test was implemented to assess the relationship between the multiple TMD symptoms reported and the potential risk factors. Results: Most participants reported a variable amount of stress. Moreover, 1528 (72.7 percent) mentioned abnormalities in sleep. About 80 percent had at least one TMD-related symptom. The multiple symptoms of TMD were identified among the 741 individuals. The following risk factors demonstrated association with a robust statistical significance (P=0.00), 1) occupation, 2) sleeping problems, 3) health concerns, 4) traumatic dental treatment, 5) various somatic symptoms, and 6) elevated HAD scale. When the outcomes of the clinical examination were analyzed, the statistical assessment could link soft tissue changes, namely; the cheek ridging and tongue indentations (P 0.00), with multiple symptoms of the condition. Conclusion: Multiple TMD symptoms were prevalent among individuals with elevated stress, abnormal sleep pattern, traumatic dental treatment, elevated HAD scale. The results highlighted the importance of psychological factors in the pathogenesis of TMD.

Attachment Loss

Objectives To assess the prevalence and extent of chronic periodontitis, and its risk factors in a Portuguese subpopulation referred to periodontal examination. Methods This retrospective cross-sectional study used a subset of data from patients who sought dental treatment in a university dental clinic in the Lisbon metropolitan area. The sample consisted of 405 individuals (225 females/180 males), aged 20–90 years. All patients underwent a full-mouth periodontal examination and chronic periodontitis was defined as Clinical Attachment Loss (CAL) ≥ 3 mm affecting two or more teeth. Aggressive periodontitis cases were excluded from the analysis. Results Prevalence of chronic periodontitis was 83.5% (95% CI [80.4–86.6%]). For these subjects, CAL ≥ 3 mm affected 86.0% (95% CI [84.7–87.2]) of sites and 83.7% (95% CI [81.7–85.6]) of teeth, respectively. Mean CAL ranged from 3.6 to 4.3 mm, according to age. In the multivariate logistic regression model, smoking (OR = 3.55, 95% CI [1.80–7.02]) and older age (OR = 8.70, 95% CI [3.66–20.69] and OR = 4.85, 95% CI [2.57–9.16]), for 65+ and 45–64 years old, respectively, were identified as risk indicators for CAL ≥ 3 mm. Conclusions This particular Portuguese adult subpopulation had a high prevalence of chronic periodontitis, with severe and generalized clinical attachment loss, and its presence was significantly associated with age and smoking. This data should serve to prepare future detailed epidemiological studies and appropriate public health programs.

Factors Associated

Objectives: This cross-sectional study aimed to evaluate the frequency and risk factors associated with cusp fractures in posterior permanent teeth. Methods: Patients presented cusp fractures on posterior permanent teeth, clinically assessed in up to 7 days after the event, and requesting dental treatment at two public services were included in this cross-sectional study. Fractured teeth already treated, with antagonist absence, or with prosthesis (total or removable) were excluded. Demographic and clinical data were collected to draw the patient profiles and establish how teeth were affected individually. Statistical analysis was performed by the Fisher exact test, and uni- and multivariate logistic regression (α = 0.05). Results: One hundred and seventy-seven (177) patients from 16 to 66 years old (±41.56), from 1998 to 2016, were included in this study. Non-functional and lingual cusps presented a higher fracture than functional and buccal cusps, respectively. Fractures were more common in teeth with isthmus wider than 1/3 of the intercuspid distance and/or more than three restored surfaces. Teeth with endodontic treatment presented a higher subgingival fracture. On lingual cusps, fracture type and location were significantly associated, being that total fractures were 3.2 times more likely to occur than partial fractures, and subgingival were 3.62 times more likely to occur than supragingival fractures. Conclusion: Indications of classic protection on functional cusps (LUBL) was refuted since, generally, nonfunctional cusps fractured more than the functional cusps. However, upper pre-molars showed more fractures in functional cusps and lower molars presented more fractures on the nonfunctional cusps. In general, lingual cusps were the most fractured and were associated with a higher prevalence of severe fractures (total fractures at the subgingival level). Fractures were more common in teeth where the restoration had an isthmus wider than 1/3 of the intercuspid distance and/or involved more than three restored surfaces. Most of the patients did not show previous symptoms and signs. Overall, teeth with endodontic treatment presented a higher subgingival fracture.

Klinische Symptome

Nathues C, Janssen E, Duengelhoef A et al. Cross-sectional study on risk factors for Porcine Reproductive and Respiratory Syndrome virus sow herd instability in German breeding herds. Acta Vet Scand 2018; 60 (1): 1–8 In mit PRRSV (Porcine Reproductive and Respiratory Syndrom Virus) infizierten Schweinebeständen zeigen die Tiere oftmals ernsthafte klinische Symptome. Die Schwere der Symptomatik hängt von der Virulenz der jeweiligen Virusstämme ab. Deshalb ist die Impfung gegen diesen Erreger sinnvoll und wird empfohlen, auch wenn sie nicht immer klinische Fälle verhindert bzw. das Virus vollends eliminiert. Aufgrund dessen rückt die Prävention durch Verbesserung der innerbetrieblichen Abläufe zunehmend in den Fokus. Um solche Maßnahmen erfolgreich etablieren zu können, ist es wichtig, den epidemiologischen Status der Herde und mögliche Risikofaktoren zu kennen. Ziel der Studie war deshalb, die Prävalenz der Infektion in Sauenbetrieben in Norddeutschland zu eruieren und verschiedene Arbeitsabläufe hinsichtlich des Risikos der Erregerverbreitung zu untersuchen.
