- Objectives: To develop a measure to assess quality of life in patients with hypodontia.Setting and sample population: Royal Devon and Exeter NHS Foundation Trust.Materials and methods: The study was divided into two parts. The first phase involved developing a patient-specific questionnaire using 22 patients with hypodontia in five focus groups. The transcripts from these groups were analysed thematically, and emerging themes used to direct the remaining focus groups. When no new themes were identified, it was assumed that data saturation was reached and no further focus groups were organised. In the second phase of the study, a health-related quality of life questionnaire was developed.Results: Analysis of transcripts revealed four themes: treatment, effect on daily activities, appearance and other peoples' reactions. These themes were incorporated into a questionnaire. The readability, ease of administration, face and content validity of the questionnaire were tested.Conclusions: A new measure for assessment of quality of life in patients with hypodontia is presented.

- OBJECTIVES: To study the prevalence of oral problems reported among a large group of adults with Ehlers-Danlos Syndrome (EDS). Furthermore, to compare proportions of disorders and general psychological well-being with those in a cohort of randomized population-based controls. DESIGN: A questionnaire study. SETTING AND SAMPLE POPULATION: A total of 265 persons with EDS (response rate 77%) and 750 controls (response rate 63%) in a population-based cohort. Sixty persons were excluded from the EDS group (support members, children, undiagnosed EDS) leaving a final study group of 144 adults. The final control group consisted of 331 persons since many had sent back unanswered questionnaires. EXPERIMENTAL VARIABLES: Questions concerning general and oral symptoms, VAS scales for masticatory muscle pain ratings and General Health Questionnaire (GHQ12) questions were included. OUTCOME MEASURE: Proportions of affirmative answers in EDS group and controls were compared. Mean values for ratings on VAS scales. Proportions of GHQ12 scores with a threshold score of four or more. RESULTS: The proportions of affirmative answers for persons with EDS concerning general health problems, oral problems and masticatory muscle symptoms were significantly higher compared with controls. In the EDS group those who had daily pain in the masticatory muscles had significantly higher mean values on the VAS scales compared with those who had pain a few days per month. A GHQ12 score of four or more was significantly more common in the EDS group than in the controls, suggesting that a decline in psychological well-being was also more common in this group. CONCLUSION: It is important that dental practitioners should be aware of the oral problems associated with EDS and the impact the disease has on quality of life.

- OBJECTIVES: To study maximal mandibular opening capacity and the prevalence of temporomandibular joint (TMJ) problems reported among a larger group of adults with Ehlers-Danlos syndrome (EDS). Furthermore, to compare proportions of disorders with those in a cohort of randomized population- based controls. DESIGN: A questionnaire study with self-registration of maximal mandibular opening capacity. SETTING AND SAMPLE POPULATION: One hundred and fourteen persons with EDS and 114 controls in a randomized population-based cohort. Experimental variables - Self-registered maximal mandibular opening capacity values that were calculated from the markings of maximal interincisal distance on spatulas and the assessments of overbite with the aid of photos. Questions concerning EDS, TMJ problems and other related questions. OUTCOME MEASURE: Mean values of maximal mandibular opening capacity compared between groups. Proportions of affirmative answers about TMJ problems compared between persons with EDS and controls who did not have the syndrome. RESULTS: The EDS persons who reported problems with poor mouth opening capacity when biting into thick pieces of food had a lower mean maximal mandibular opening value compared with the other EDS persons (p < 0.05). The proportions of affirmative answers concerning mobile joints during mouth opening, present TMJ problems, poor mouth opening capacity when biting into thick food, clicking, crepitations and permanent locking were greater compared with the controls (p < 0.05). CONCLUSION: These data corroborate the reports in literature that persons with EDS are naturally predisposed to TMJ problems. The self-registration of maximal mandibular opening capacity was a useful diagnostic tool to provide an objective clinical measure of movement capacity of the TMJ. The clinical measure was in line with the affirmative answers on having problems with poor mouth opening capacity among the EDS persons.

- When treating patients with orthognathic surgery, there might be a risk of obstructive sleep apnoea (OSA) due to soft tissue changes in the upper airways, especially in patients treated with isolated mandibular setback or mandibular setback in combination with maxillary advancement. In the present study, we assessed respiratory function during sleep with home cardiorespiratory polygraphy in 62 patients who had not been previously been diagnosed with OSA at three times: prior to orthognathic surgery for aesthetic and functional indications, and then 3 months and 1 year after surgery. We evaluated surgical displacement based on measurements in three dimensions using pre- and post-operative computed tomography. There were only minor changes in the respiratory parameters such as the apnoea-hypopnoea index (AHI), the apnoea-hypopnoea index in the supine position (AHIsup), the oxygen saturation index (ODI) and the snore index. There was no significant correlation between surgical displacement and the AHI, AHIsup and ODI. There was a weak but significant correlation between vertical displacement of the anterior mandible and the snore index. Within the limitations of the present study, the risk for iatrogenic obstruction of the upper airways seems to be low in patients without OSA treated with orthognathic surgery.

- OBJECTIVES: To present the development of an experimental model in rats for translational expansive tooth movement. SETTING AND SAMPLE: Section of Periodontology at Department of Dentistry Aarhus University. Twenty male Wistar rats in two pilot experimental settings plus seven animals without any intervention serving as controls. MATERIAL AND METHODS: The second molar (group P1) or the second and third molar (group P2) in the maxillae of the animals were moved buccally using transpalatal β-titanium springs. In the group P2, two spring types (high force and low force) and two preangulations (0° passive or 30° torsion moment) were tested. The amount and type of tooth movement achieved and the resulting skeletal effect were assessed on microCT images, histological analysis was performed on few selected specimens. RESULTS: Expansive translational root movement amounting half a tooth width was achieved. Comparison of the amount of tooth movement at the right and left side of the maxilla showed that the expansion was rather symmetrical in the P2 group. Skeletal widening of the maxilla contributed in the P2 group to approximately one-third of the total root movement, whereas two-thirds were dental movement. CONCLUSION: With the model used in the P2 group, further research on translational expansive tooth movement and its effect on the periodontium can be pursued. In models for orthodontic expansion, it is strongly recommended to separately evaluate skeletal and dental effects.

- OBJECTIVE: To evaluate three different retention methods in compliant patients after 2 years of retention. DESIGN: Three group randomized controlled trial. MATERIALS AND METHODS: The sample was recruited from patients having their fixed appliance treatment between 2001 and 2007. Seventy-five patients (45 girls and 30 boys with a mean age of 14.4 years at start of retention) were randomized into three retention methods: vacuum-formed retainer in the maxilla and bonded canine-to-canine retainer in the mandible (Group V-CTC), vacuum-formed retainer in the maxilla combined with stripping of the 10 proximal surfaces of the lower mandibular anterior teeth (Group V-S) and prefabricated positioner covering the teeth in the maxilla and the mandible (Group P). The following linear measurements were performed: Little's irregularity index (LII), intercanine width, intermolar width, arch length, overjet, overbite and body height growth. Registrations were made before orthodontic treatment, at start of retention, after 12 and finally 24 months in retention. Differences in means between groups were tested by one-way analysis of variance (SPSS). RESULTS: After 2 years all three retention methods were successful in retaining orthodontic treatment results. The major part of relapse took place during the 1st year of retention. CONCLUSIONS: All 3 types of retention methods were equally effective in controlling relapse to a clinically acceptable level.

- OBJECTIVES: To compare self-reported pain levels across various treatment phases using passive self-ligating (Damon) and conventional (Victory) standardized fixed appliance systems.MATERIALS AND METHODS: Adolescents (12-17 years old) with crowding and displaced teeth, planned for non-extraction treatment, were recruited from four orthodontic clinics. They were randomized into stratified blocks (1:1 ratio) using concealed allocation to receive Damon Q™ (34 boys, 28 girls) or Victory™ (39 boys, 31 girls). Pain and analgesic intake were assessed on seven different occasions with validated self-report questionnaires using a 10-grade scale.RESULTS: Of the 132 patients included, six were lost to follow up. Clinically relevant mean pain scores (≥4) were registered in both groups after bonding upper and lower arches and after insertion of 0.019 × 0.025 stainless steel archwire. The highest mean scores were reported on day two after bonding the upper arch (Damon 5.96, Victory 7.18, P = .011). In both groups, at least 40% reported taking analgesics during various treatment phases. The Damon group reported a lower intake of analgesics on days one and two (P = .042 and .037) after treatment initiation. In the entire sample, boys reported significantly higher mean pain scores than girls on the second and third days after bonding (P = .008 and .026, respectively).CONCLUSIONS: Lower pain levels were reported from the Damon group after bonding. In general, boys reported higher pain than girls did. Clinicians and adolescents need to be aware that clinically relevant pain levels can be expected not only after bonding but also in later phases.
