- INTRODUCTION: Treatment for malocclusion can cause discomfort and pain in the teeth and periodontium, which may impair masticatory efficiency. The glucose concentration method is widely used to assess masticatory efficiency for its convenience in the clinical situation, although its validity has not been shown.OBJECTIVE: The aims were to determine the validity of the glucose concentration method and investigate if this method can be applicable to orthodontic patients with braces.DESIGN: Sixteen healthy individuals (7 men, 9 women, and 26±5 years old) and 16 patients with malocclusions needing orthodontic treatment (5 men, 11 women, and 26±4 years old) participated. Glucose concentration was measured after 5-, 10-, and 15-s mastication of gummy jelly and compared to Hue values obtained from the color-changing gum method (reference method). In addition, all participants were asked to fill out the Oral Health Impact Profile questionnaire (OHIP) to assess differences in perception related to the mouth before and after the placement of braces.RESULTS: = 0.711, P < 0.001) Masticatory efficiency assessed by both methods was significantly lower in orthodontic patients compared to controls (P<0.05), even though it was not affected by bonding (P>0.09). In addition, OHIP scores in physical pain dimension and psychological disability were higher in orthodontic patients than in the control group (P<0.005).CONCLUSION: Measurement of glucose concentration was confirmed as a reliable and convenient method for assessing masticatory efficiency. Furthermore, it appears that this method is applicable to patients with braces whose perception in the oral cavity could change.

- Background: It is not clear to what extent chewing is improved by unilateral oral rehabilitation with implant-supported fixed partial prostheses (ISFPPs). Objectives: This study aimed to investigate whether patients treated with unilateral ISFPPs in the maxilla use their prostheses during mastication to the same extent as they used their contralateral natural teeth. A further aim was to investigate whether there is a correlation between preferred chewing side and laterality. Methods: Chewing side preference was assessed in 15 participants treated with unilateral ISFPPs in the maxilla. The first, second, third, fifth and tenth chewing cycles were assessed, and the test was repeated 10 times. All participants also answered a questionnaire about their chewing side preference. Results: Most of the participants presented bilateral chewing, but two (13%) chewed only on the ISFPP. There was no statistically significant association between the objectively assessed chewing side and dental status (natural teeth or ISFPPs) during any of the recorded chewing cycles (p >.1). There were statistically significant correlations between both the subjectively reported usually preferred chewing side and the subjective chewing side preference during the test and the objectively assessed chewing side for the first three chewing cycles (p <.01). No correlation was found between handedness and the objectively assessed chewing side. Conclusion: In the present study, most participants chewed bilaterally, and chewing was performed both on the ISFPP and on the natural teeth. No correlation was found between the preferred chewing side, objectively or subjectively determined and laterality.

- BACKGROUND: Both temporomandibular disorders myalgia (TMDM) and fibromyalgia (FM) have been linked to central and peripheral changes in serotonin availability. The precursor of serotonin, tryptophan (TRP), is mainly catabolised via another pathway to produce kynurenine (KYN), but whether changes of this pathway are present in TMDM and FM are still unclear.OBJECTIVE: The aim was to explore blood plasma concentrations of TRP and KYN in TMDM and FM in an attempt to identify novel associations for future research.METHODS: Plasma of 113 female participants (17 TMDM, 40 FM and 56 healthy pain-free controls) were analysed for TRP and KYN concentrations. The degradation of TRP via the KYN pathway was indicated by the KYN to TRP ratio (KYN/TRP). Pain intensities were assessed with the Graded Chronic Pain Scale (GCPS) and Visual Analogue Scale (VAS). Psychological symptoms were evaluated using the Hospital Anxiety and Depression Scale (HADS), Patient Health Questionnaire (PHQ-9) and General Anxiety Disorder scale (GAD-7).RESULTS: In TMDM there was a negative correlation between TRP and pain intensity (rs = -0.55 P = .023) and positive correlations between KYN/TRP and pain intensity (rs = 0.59 P = .013). In FM, KYN/TRP was negatively correlated with anxiety symptoms (rs = -0.36 P = .022) and a trend towards significantly lower TRP levels was found compared to controls (P = .05).CONCLUSION: The association between KYN/TRP and pain intensity as well as anxiety ratings in this small exploratory study may indicate that KYN/TRP could be a relevant indicator for symptom severity in TMDM and FM. Further investigations of the KYN pathway in chronic myalgia are warranted.

- OBJECTIVES: To explore impairments due to tooth loss and expectations of prosthetic replacements in an urban group and a rural group of patients in Sweden. MATERIAL AND METHODS: Semi-structured interviews were performed on 35 partially edentulous patients from prosthodontic specialist clinics located in an urban area and a rural area in Sweden. The interviews focused on impairments due to tooth loss and expectations of prosthetic restorations. Analysis was made using the grounded theory approach, allowing in-depth investigation of the phenomenon. RESULTS: Functional, aesthetic and social impairments were mentioned, and coping strategies (eg chewing differently and laughing less) and modifications (eg age, time and social setting) of the impairments were described. The rural patient group accepted impairments somewhat better than the urban one. Otherwise, there was only minor difference between the groups. Removable prosthodontic restorations were more acceptable among rural patients. Urban patients insisted more often on implant-based restorations and had higher expectations of longevity. Patients with minor impairments still wanted treatment, based on concerns about the future of their dentition. The interviews themselves generated new thoughts in the patients and were thus considered valuable by the patients. CONCLUSIONS: Impairments due to tooth loss and expectations of prosthetic replacements were expressed in the same way in the rural and urban patient groups. However, in the rural population, there was a higher acceptance of impairments and also of removable prosthetic restorations, whereas the urban population expressed a higher demand for implant-based restorations.
