Craniofacial fractures sustained under the influence of alcohol: what are the differences between the sexes?

OBJECTIVE: To identify mechanisms and types of injuries in patients having sustained craniofacial fractures under the influence of alcohol, and to compare the frequencies of them between males and females. MATERIALS AND METHODS: Patients included were adults who had been diagnosed with craniofacial fractures at Töölö Hospital Emergency Department, Helsinki University Hospital, Finland, and who had been under the influence of alcohol at the time of injury. The primary outcome variables were assault-related and fall-related injury mechanisms. The secondary outcome variables were other injury mechanisms, time of accident, type of craniofacial fracture and severity of facial fracture. The primary predictor variable was sex. The control variable was age at the time of injury. The statistical modelling was executed using logistic regression. RESULTS: Of the total of 2,859 patients with craniofacial fractures, 1,014 patients (35.5%) fulfilled the inclusion criteria. Males predominated (84.6%). Assault (38.0%) was the most frequent aetiology. Compared to the odds of females, males had 2.8 times greater odds for assault, 2.4 times greater odds for isolated cranial fracture and 1.7 times greater odds for a facial injury severity score of ≥ 3. Females had 2.0 times greater odds for any fall compared to the odds of males. CONCLUSIONS: Particularly male patients are frequently under the influence of alcohol at the time of injury, predisposing them to assault and severe facial fractures more often than females. Codes of practice on how to identify unhealthy alcohol use and how to intervene are recommended.

Smoking's impact on pocket closure after nonsurgical periodontal treatment in relation to bleeding on probing.

OBJECTIVES: Our aim was to investigate the impact of smoking on pocket closure at six months after treatment of severe periodontitis, in relation to residual clinical inflammation. METHOD AND MATERIALS: The clinical records of deep pockets (probing depth≥6 mm, n=984) in 46 individuals with periodontitis were analyzed. Following baseline clinical assessments (plaque index, probing depth, clinical attachment level, and bleeding on probing), non-surgical periodontal treatment was performed. Clinical assessments were repeated at 2 and 24 weeks after periodontal therapy. A logistic regression model using generalised estimation equations (GEE) adapting the cluster robust standard errors was performed to investigate potential associations between bleeding on probing and pocket closure at post-treatment 24 weeks. RESULTS: Absence of bleeding at two weeks after non-surgical treatment related to pocket closure after six-months. Pockets that do not bleed neither at baseline nor two weeks (OR=2.7; P <.005) and pockets of non-smokers (OR=6.32; P <.001) and females (OR=1.79; P =.022) associated with pocket closure at six months. CONCLUSION: Pocket closure is associated with being a non-smoker and the absence of inflammation after non-surgical periodontal treatment, which indicates the importance of smoking cessation and inflammation control in achieving optimal clinical outcomes.

Implementing online learning of Diagnostic Criteria for the Temporomandibular Disorders (DC/TMD) protocol in undergraduate dental education.

INTRODUCTION: The Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) is part of the undergraduate dental curriculum. Online teaching has nowadays become common also in dentistry. OBJECTIVE: To compare undergraduate students' self-assessed ability and satisfaction with learning DC/TMD Axis I between traditional and online learning and to evaluate the possible gains of online teaching. MATERIAL AND METHODS: Third-year undergraduate dental students in 2018 (traditional learning, Group 1, n = 43/50) and in 2019 (online learning, Group 2, n = 34/50) at the University of Oulu, Finland evaluated their self-assessed ability and satisfaction with learning DC/TMD clinical examination and diagnostics on a 10-point scale. Additionally, those participating in online courses answered to two open-ended questions; Group 2 (n = 50) and another group from the University of Eastern Finland in 2019 and 2020 (n = 75, Group 3). Total of 105/125 students (84%) responded. Content analysis was used to open-ended responses. RESULTS: The online course reported significantly higher self-assessed ability in measurements (p = 0.004), identifying referred pain (p = 0.043) and statement for the diagnostics (p = 0.017) and also higher self-assessed satisfaction in measurements (p = 0.046). According to the content analysis, essential gains of online teaching were efficient learning, videos and exercises, and adjustability to own timetable. CONCLUSION: The online learning course can be considered as a good option for traditional learning of the DC/TMD protocol.

Immunoexpression pattern of TLR3 and TLR7 in minor salivary gland adenoid cystic carcinoma and its role in prognosis.

OBJECTIVES: Adenoid cystic carcinoma (ACC) of the salivary glands has poor long-term prognosis and a high metastatic rate. Toll-like receptors (TLRs), first-line immune activators, have been associated with both tumor progression and suppression. We aimed to study TLR3 and TLR7 behavior in ACC. MATERIALS AND METHODS: We studied TLR3 and TLR7 immunoexpression of 46 minor salivary gland ACCs diagnosed at the Department of Otorhinolaryngology - Head and Neck Surgery, Helsinki University Hospital, Helsinki, Finland over the period 1974-2012. The associations of TLR3 and TLR7 immunoexpression with clinicopathological factors were evaluated by χ2-test and Fisher's exact test. RESULTS: In the majority of samples, both TLR3 and TLR7 were immunoexpressed in cytoplasm. The immunoexpression was heterogeneous between individual tumors. Stronger TLR7 immunoexpression associated with recurrence rate and poorer disease-specific survival (DSS). TLR3 did not associate significantly with survival although we found an inverse correlation between TLR3 and TLR7 immunopositivity. Hence, when TLR3 immunoexpression was negative or mild, TLR7 immunoexpression was moderate to strong, and vice versa. CONCLUSIONS: TLR3 and TLR7 are immunoexpressed in minor salivary gland ACC. TLR7 is potentially an independent prognostic marker for recurrence rate and DSS.

Concordance of Fathers and Mothers in the Assessment of Their 5-Year-Old Child's Dental Fear.

The aim of this study was to evaluate the concordance of parents' assessments of their child's dental fear. Cross-sectional secondary analysis used data from the multidisciplinary FinnBrain Birth Cohort Study. Child dental fear was assessed at age 5 with the Finnish translation of the modified Children's Fear Survey Schedule Dental Subscale (CFSS-M) by both fathers (n = 588) and mothers (n = 1100). Reply alternatives were from 1 = not afraid to 5 = very afraid and 6 = no experience coded as missing and 1. In total, 514 mother-father pairs were eligible for the analyses. Descriptive statistics, percentage agreement and Cohen's Kappa coefficients were used in the analyses. The concordance of parents' assessments was poor (Kappa range 0.072-0.258). The majority of parents replied "No Experience" to items related to invasive treatment or being unable to breathe. Thus, coding of this reply alternative had a significant impact on the mean values of the child's fear. When assessing the fear of a five-year-old child, it might not be safe to rely only on one parent's assessment, and whether or not the child has experience with the question asked should also be considered.

Two-Year Trajectories of Dental Anxiety in Parents and Their Association with Parents' and Children's Oral Healthcare Procedures in FinnBrain Birth Cohort Study.

We aimed to identify parents' dental anxiety trajectories and the association of the trajectories with the number of parents' and their children's oral healthcare procedures in the FinnBrain Birth Cohort Study. Dental anxiety was measured with the Modified Dental Anxiety Scale at gestational weeks (gw) 14 and 34, as well as 3 and 24 months (mo) after childbirth. Oral healthcare procedures from gw14 to 24 mo were obtained from the national patient data register and categorized as preventive and treatment. Trajectories were identified with latent growth mixture modelling for 2068 fathers and 3201 mothers. Associations between trajectories and procedures adjusted for education were analyzed using unordered multinomial logit models. Fathers' trajectories were stable low (80.1%), stable high (3.4%), stable moderate (11.0%), moderate increasing (3.9%) and high decreasing (1.6%). Mothers' trajectories were stable low (80.7%), stable high (11.2%), moderate increasing (5.3%) and high decreasing (2.8%). Mothers with decreasing dental anxiety had a higher number of preventive and treatment procedures. Fathers with decreasing dental anxiety had a higher number of preventive and treatment procedures, while fathers with increasing dental anxiety had fewer procedures. Children of mothers with stable low dental anxiety had higher number of preventive procedures. There seems to be a two-way association between dental anxiety trajectories and oral healthcare procedures.

Autonomic Nervous System Activity and Dental Anxiety in the Northern Finland Birth Cohort (NFBC1966) Population.

Autonomic nervous system (ANS) activity may be associated with dental anxiety; however, no studies exist on the topic. The aim of this study was to assess if ANS activity and dental anxiety are associated. Data were collected as part of a Northern Finland Birth Cohort Study, NFBC1966, at the age of 46 years with eligible data on 1905 participants. Dental anxiety was measured using the Modified Dental Anxiety Scale (MDAS) categorized as follows: 19-25 = high, 10-18 = moderate, 5-9 = no to low dental anxiety. Heart rate variability (HRV) data were collected using an HR monitor and a standard lead-II electrocardiogram (ECG). Baroreflex sensitivity (BRS) was calculated from continuous ECG and blood pressure signals. Participants were categorized into three groups as follows: Low = the lowest 20th percentile, Mid = medium 21-79th percentile, and High = the highest 20th percentile according to their ANS variables. The associations between the MDAS and ANS activity parameters were evaluated using unordered multinomial logit models adjusted for comorbidities, ß-blockers, BMI, smoking, and education. High heart rate, reduced HRV, low cardiac vagal modulation, and poor BRS were associated with moderate dental anxiety, and high cardiac vagal modulation and good BRS were associated with no to low dental anxiety. Poorer ANS activity might predispose some to dental anxiety, and better ANS activity might protect from dental anxiety.

Appearance and recurrence of odontogenic keratocysts.

OBJECTIVE: The purpose of this study was to evaluate the appearance, histopathological features, and recurrence of odontogenic keratocysts (OKCs) from a large single institute registry over a 36-year period. MATERIALS AND METHODS: A total of 226 cases of OKC were identified in 174 patients over a 36-year period in a single institute in Southwestern Finland. Histological specimens were re-evaluated. The patient's age, sex, location, recurrence, and histopathological features of the OKC were the study variables. RESULTS: OKCs occurred more frequently in men, the mean age was 46 years, and the most frequent site was the lower jaw. Recurrence rate was 21%. Histopathologically, inflammation was present in 95% and satellite cysts in 10% of cases. In patients diagnosed with satellite cysts, OKC recurred in 50% of cases, while the corresponding figure for patients without satellite cysts was 17%. CONCLUSIONS: Compared with the literature, patients were older and inflamed cysts were found more frequently. Satellite cysts occurred only in association with chronic inflammation. Based on the results, regular radiographic evaluation is important among patients aged 10-29 years to detect OKCs and to treat them before enlargement, infection, and inflammation. Satellite cysts should be reported and may be a sign of increased risk of OKC recurrence.

Effects of the COVID-19 pandemic on orthodontic care in Finland.

OBJECTIVES: To investigate the measures that were taken to limit the risk of COVID-19 contagion, how the risk of adverse effects on patient treatment outcomes was mitigated in orthodontic practices in Finland during the COVID-19 pandemic, and how these measures affected the course of orthodontic treatment. MATERIALS AND METHODS: In January 2021, an online questionnaire was sent by email to the members of the Orthodontic Division of the Finnish Dental Association Apollonia (n = 361). An additional inquiry was sent to the chief dental officers of 15 health centers. RESULTS: A total of 99 clinically active members (39.8%) responded to the questionnaire. Of them, 97.0% had made changes in their practices, e.g. using additional protective gear such as visors (82.8%), incorporating preoperative mouthwashes (70.7%), and limiting the use of turbines (68.7%) and ultrasonics (47.5%). Two in three respondents reported temporary lockdowns (mean 1.9 months, range 0.3-5.0 months), during which some occlusions slightly regressed (30.2%) and some relapsed to a previous stage of treatment (9.5%). During this study, 59.6% of respondents reported that some treatments were still behind schedule. One in three respondents had used teleorthodontics because of the pandemic. CONCLUSIONS: Preventive measures and changes in treatment procedures were implemented according to the local COVID-19 situation. Some treatments were prolonged, e.g. because of lockdowns or patient's fear of contracting COVID-19 whilst receiving treatment. New methods like teleorthodontics were introduced for coping with the increased workload.

Characteristics of Associated Injuries in Children and Teenagers With Craniofacial Fractures.

The incidence of pediatric craniofacial fractures and heterogeneity of fractures is known to increase with age. This study aimed to determine the occurrence of associated injuries (AIs) to craniofacial fractures and identify differences in patterns of and predictors for AIs in children and teenagers. A 6-year retrospective cross-sectional cohort study was designed and implemented. The study population included 397 patients aged 19 years or less diagnosed with craniofacial fracture at Helsinki University Hospital from 2013 to 2018. Boys (71.0%) and teenagers (64.7%) were predominated. Associated injuries were more common in teenagers than children. Teenagers had more often AI in 2 or more organ systems. Assault and intoxication by alcohol were observed only in teenagers and predominantly boys. A total of 27.0% of all patients sustained AIs. In 18.1%, brain injury was reported. In children, motor vehicle accident (MVA) was an independent predictor for AI. In teenagers, independent predictors for AI were female sex, isolated cranial fracture, combined cranial fracture, and high-energy trauma mechanism. Injury patterns and AI related to craniofacial fractures in the pediatric population are age-specific, requiring multidisciplinary collaboration in the diagnosis, treatment, and follow-up of such trauma. Predictors for AIs increase in complexity with age, and the role of sex as a predictor is evident in teenagers.

Retrospective Analysis of Artifacts in Cone Beam Computed Tomography Images Used to Diagnose Chronic Rhinosinusitis.

BACKGROUND: Cone beam computed tomography (CBCT) is frequently used to corroborate the signs and symptoms of chronic rhinosinusitis (CRS). However, artifacts induced by dental restorations might complicate the diagnosis of CRS. Here, we assessed the frequency and location of artifacts in CBCT images taken to confirm the CRS. METHODS: All CBCT images of the patients referred to the Emergency Radiology unit, Turku University Hospital, with an indication of CRS in 2017 were re-examined. The prevalence of the artifacts was analyzed in three cross-sectional views and three horizontal levels delimited by anatomical landmarks. RESULTS: In total, 214 CBCT images of patients with CRS were evaluated. The diagnosis of apical periodontitis (AP) was impaired by artifacts present in 150/214 images (70%). The diagnosis of CRS was impaired in 5 of the 214 images (2.3%). The main origins of the artifacts were large dental fillings or crowns, and endodontic fillings were present in 95% (203/214) and 52% (111/214) of the images, respectively. CONCLUSIONS: AP as an etiology of CRS is possible to miss because of artifacts originating from dental and endodontic fillings in the CBCT images of the paranasal sinuses.

Longitudinal trends in temporomandibular joint disorder symptoms, the impact of malocclusion and orthodontic treatment: A 20-year prospective study.

BACKGROUND: Studies on the association between malocclusion and temporomandibular joint disorder (TMD) have reported conflicting results. OBJECTIVES: To determine the impact of malocclusion and orthodontic treatment on symptoms of TMD. METHODS: At 12 years, 195 subjects fulfilled a questionnaire regarding TMD symptoms and participated in an oral examination including preparation of dental casts. The study was repeated at ages 15 and 32. The occlusions were assessed by applying the Peer Assessment Rating (PAR) Index. Associations between the changes in PAR scores and TMD symptoms were analysed with the chi-square test. A multivariable logistic regression was used to calculate the odds ratios (OR) and 95% confidence intervals (CI) of TMD symptoms at 32 years predicted by sex, occlusal traits and orthodontic treatment history. RESULTS: One in three subjects (29%) was orthodontically treated. Sex was associated with more self-reported headaches by females at 32 years (OR 2.4, 95% CI 1.05-5.4; p = .038). At all time points, any crossbite was significantly associated with greater odds for self-reported temporomandibular joint (TMJ) sounds at 32 years (OR 3.5, 95% CI 1.1-11.6; p = .037). More specifically, association occurred with posterior crossbite (OR 3.3, 95% CI 1.1-9.9; p = .030). At 12 and 15 years, boys whose PAR score increased were more likely to develop TMD symptoms (p = .039). Orthodontic treatment had no impact on the number of symptoms. CONCLUSIONS: Presence of crossbite may increase the risk of self-reported TMJ sounds. Also, longitudinal changes in occlusion may have an association with TMD symptoms while orthodontic treatment is not associated with the number of symptoms.

Gender differences in the association between malocclusion traits and oral health-related quality of life in Finnish adults.

We aimed to evaluate the gender-specific associations of malocclusion traits with oral health-related quality of life (OHRQoL) among Finnish adults. Data were obtained from the Health 2000 Survey, Finland. Included participants (n = 3993) were ≥30 years old with OHRQoL and occlusion data. OHRQoL was measured using the 14-item Oral Health Impact Profile (OHIP-14). OHIP-14 severity mean score, prevalence of impacts, and means of seven dimensions were outcomes. Explanatory variables were any malocclusion trait, increased overjet, negative overjet, open bite, deep bite, and crossbite/scissor bite. Logistic (prevalence) and cumulative (severity) regression models were adjusted for age, decayed teeth, deep periodontal pocket, occluding pairs, orthodontic treatment, and self-perceived health. Gender modified the association between any malocclusion trait and OHRQoL, with the association being stronger in females. Females without any malocclusion trait (OR = 1.62, 95% CI = 1.14-2.28) or without crossbite/scissor bite (OR = 1.68, 95% CI = 1.16-2.43) had better OHRQoL (lower prevalence) than those with malocclusions. Males without increased overjet (OR 1.50, 95% CI = 1.04-2.17) had lower mean OHIP-14 severity score than males with increased overjet, after adjustments. The association between psychological and physical disability and malocclusion traits was different between males and females. Gender differences in the impact of malocclusion traits should be considered when assessing orthodontic treatment need.

Otologic injuries are frequent in pediatric patients with temporal bone fractures.

This retrospective study aimed to clarify the occurrence and types of otologic injuries in children and adolescents with skull fractures. Files of all patients under 18 years of age who had been diagnosed with skull fractures at a tertiary trauma centre were included. The primary outcome variable was the presence of any otologic symptom or finding. Secondary outcome variables were clinically detected and radiologically detected otologic injuries. The primary predictor variable was a temporal bone fracture. Other study variables were sex, age, mechanism of injury, traumatic brain injury, and mortality. A total of 97 patients were identified for the study. Otologic symptoms and findings were frequent (33.9%). The most common clinical findings were bleeding from the external auditory canal (18.6%) and hemotympanum (13.4%). The prevailing radiological finding was blood and/or cerebrospinal fluid in the middle ear (30.9%). Patients with fractures of temporal bone had a 29-fold risk for otologic symptoms or findings (RR 28.9, 95% CI 4.1-202.9, p < 0.001) relative to those who did not have a temporal bone fracture. Severe otologic complications, such as permanent hearing loss (6.2%), cerebrospinal fluid leak (5.2%), or facial nerve palsy (1%), were infrequent. Within the limitations of the study it seems that there is the necessity of otoscopy in all pediatric patients with blunt head trauma. In case of positive otologic findings, the patient should undergo imaging and ENT consultation.

Concurrent changes in dental anxiety and smoking in parents of the FinnBrain Birth Cohort Study.

We evaluated associations between changes in dental anxiety and tobacco use, adjusted for general anxiety and depressive symptoms. The FinnBrain Birth Cohort Study data, collected at gestational weeks 14 and 34 and at 3 months postpartum, were used. Questionnaires included the Modified Dental Anxiety Scale (MDAS), the Edinburgh Postnatal Depression Scale (EPDS), and the anxiety subscale of the Symptom Checklist-90 (SCL). Smoking was categorized as "stable non-smoking", "started smoking", "quit smoking", and "stable smoking". Changes in smoking and dental anxiety were evaluated "during pregnancy" (i.e., from gestational week 14 to gestational week 34) in 2442 women and 1346 men and "after pregnancy" (i.e., from gestational week 34 to 3 months postpartum) in 2008 women and 1095 men. Changes were evaluated in three smoking categories (stable non-smoking, fluctuating, and stable smoking), using data from all three time-points (1979 women and 1049 men). Modeling used repeated measures analysis of covariance. Stable smoking mothers had statistically significantly higher levels of dental anxiety (mean MDAS 12.3-12.6) than non-smoking mothers (mean MDAS 10.1-10.7) or mothers who smoked at some point during pregnancy (mean MDAS 10.8-11.5). A similar tendency was observed in fathers. However, no systematic change in dental anxiety by changes in smoking habits was observed. Those smoking during pregnancy and with high dental anxiety may need special support for smoking cessation.

Accuracy of aMMP-8 point-of-care test in indicating periodontal treatment outcomes in stage III/IV periodontitis: A 24-week follow-up study.

OBJECTIVE: To analyse the correspondence between aMMP-8 PoC test results and the clinical endpoints of non-surgical periodontal treatment in stage III/IV periodontitis. BACKGROUND: The diagnostic success of the active-matrix metalloproteinase-8 (aMMP-8) point-of-care (PoC) test has been demonstrated in various studies, but the evidence of its accuracy following periodontal treatment is limited. MATERIALS AND METHODS: Altogether 42 stage III/IV grade C periodontitis patients were included in this prospective diagnostic study. Clinical periodontal indices were recorded, aMMP-8 PoC test was applied and mouthrinse was collected before and at 6, 12 and 24 weeks after non-surgical periodontal treatment. Quantitative aMMP-8 levels were determined with immunofluorometric assay (IFMA) for the verification of the PoC test results. The accuracy of the aMMP-8 PoC test was assessed using previously established clinical endpoints as references. RESULTS: Sensitivity and specificity of aMMP-8 PoC test to indicate clinical endpoints were ranged as follows: Sensitivity 71.4% at baseline, 39.3%-42.4% at week 6, 28.6%-32.4% at week 12 and 35.3%-42.9% at week 24; specificity 64.3%-80% at week 6, 40%-57.1% at week 12 and 56%-64.3% at week 24. CONCLUSIONS: The accuracy of aMMP-8 PoC test in identifying clinical endpoints after non-surgical periodontal treatment is reduced in relation to baseline. Individual healing patterns of each diseased pocket eventually limit the accuracy of the dichotomous aMMP-8 oral rinse test during the post-treatment period.

Histopathological findings of oral epithelial dysplasias and their relation to malignant transformation.

OBJECTIVES: Oral squamous cell carcinomas (OSCCs) are often diagnosed late. This study aimed to determine how frequently oral epithelial dysplasia (OED) transforms to OSCC and to identify histological features that could influence the rate of malignant transformation. MATERIALS AND METHODS: The study was a retrospective analysis of OED over 29 years at the Institute of Dentistry, University of Turku, Finland. OEDs with co-existing carcinomas were excluded from the data (5.8%). OED patients who developed carcinoma were identified from the Finnish Cancer Registry database. RESULTS: Altogether 681 OED patients had a mean age of 59.0 years, and the male:female ratio was 0.67. Of all OED samples, 21.8% were on the tongue, followed by lining mucosa (21.3%), lip (5.3%), and masticatory mucosa (4.85%). In addition, 46.7% had no location cited. The prevalence of mild dysplasia was 62.4%, moderate dysplasia 29.1%, and severe dysplasia 3.2%. Of the patients, 94.7% had an additional histological diagnosis alongside OED. Candidiasis, lichenoid inflammation, and ulcer were found in 18.2%, 0.0%, and 22.7% of severe dysplasias, in 12.1%, 12.2%, and 22.7% of moderate dysplasias, and in 6.6%, 12.2%, and 15.8% of mild dysplasias, respectively. An additional histopathological diagnosis did not increase the risk for OED to transform to OSCC. In a mean time of 5.2 (range 0.7-29.0) years, 7.5% of OED patients developed OSCC. CONCLUSIONS: Location on the tongue and the more severe OED grades increased the risk of malignant transformation of OED. These patients may benefit from an intensified follow-up schedule to ensure early diagnosis of OSCC.

Parent's self-reported tooth brushing and use of fluoridated toothpaste: Associations with their one-year-old child's preventive oral health behaviour.

OBJECTIVE: The aim of the study was to examine if the tooth brushing frequency and use of fluoridated toothpaste of the mother and father were associated with the tooth brushing frequency and use of fluoridated toothpaste for their 1-year-old child. METHODS: This cross-sectional study is part of the FinnBrain Birth Cohort Study. Questionnaire data were obtained from 1672 mothers and 867 fathers on tooth brushing and use of fluoridated toothpaste, age, education, number of siblings and parity (when the child was 1-year-old). For 763 families (mother and father), data from both parents were available. Tooth brushing was dichotomized to at least twice daily (2× day) and less than 2× day, and use of fluoridated toothpaste for child to at least once daily and less than once daily. The association between brushing of child's teeth (both parents less than 2× day) and use of fluoridated toothpaste for the child (both parents less than once daily) with parent's own tooth brushing was modelled with logistic regression analyses adjusted for family-related variables (parents' age and education, number of older siblings) using odds ratios (OR) and 95% confidence intervals (CI). RESULTS: Families in which both parents brushed their own teeth less than 2× day were more likely to brush their child's teeth less than 2× day than families in which both parents brushed their own teeth 2× day (OR = 9.23; 95%CI = 5.42-15.69). The likelihood of not brushing the child's teeth 2× day was less strong when at least one of the parents brushed his/her own teeth 2× day (mother 2× day: OR = 1.97; 95%CI = 1.25-3.10; father 2× day: OR = 2.85; 95%CI = 1.51-5.40). CONCLUSIONS: Less frequent tooth brushing of both mothers and fathers was strongly associated with less frequent tooth brushing of their child. When educating parents on child oral home care, parents' own home care and inclusion of fathers also need more attention.

Association of service use with subjective oral health indicators in a freedom of choice pilot.

OBJECTIVES: A freedom of choice pilot provided access to private oral health care services without queuing and with fixed public service-fees for participants in Tampere region, Finland in 2018-2019. The aim of this study was to investigate how use of oral health care services differed by demographics, socioeconomic status, dental fear, and self-reported oral health in this pilot. MATERIAL AND METHODS: SMS-messages including a link to online questionnaire were sent to participants who had booked an appointment, and to those who had not booked an appointment despite registering to pilot. We categorized participants to (1) those who had booked their first appointment before receiving SMS (visitors), (2) those who booked an appointment after receiving the SMS-message (late-visitors), and (3) those who had not booked an appointment during pilot (nonvisitors). We used regression analysis to estimate the association of age, gender, dental fear, economic situation, Oral Health Impact Profile-14-severity (oral health-related quality of life [OHRQoL]), self-reported oral health and need for oral health care (exposures) with oral health care service use during the pilot (outcome). RESULTS: Out of 2300 participants, 636 (28%) responded. Late-visitors were more likely older and reported more likely need for oral health care, poorer oral health and OHRQoL than visitors or nonvisitors. Nonvisitors were younger and had better OHRQoL than the others. The differences in the service use by gender, economic situation, and dental fear were small. CONCLUSIONS: Service use during the pilot depended on the subjective oral health. Our findings highlight the potential of reminders in increasing care use among those with perceived need for services.

Craniofacial microsomia - more than a structural malformation.

OBJECTIVES: To analyse the prevalence and distribution of craniofacial microsomia (CFM) cases in Finland and their most frequent comorbidities. The second aim was to analyse the patients' need for specialized healthcare services. MATERIALS AND METHODS: Data were gathered from two complementary registers: The Register of Congenital Malformations and the Care Register for Social Welfare and Health Care (Hilmo) of the Finnish Institute for Health and Welfare (THL). RESULTS: The prevalence of CFM patients in Finland was 1:10 057. They were evenly distributed across the five university hospital districts. Their most frequently used ICD-10 diagnosis codes were F40-48 (Neurotic, stress-related and somatoform disorders), 60% of patients in adolescent and adult psychiatry; Q67.0 (Facial asymmetry), 43% in plastic surgery; Z00.4 (General psychiatric examination, not elsewhere classified), 31% in child psychiatry; Z31.5 (Genetic counselling), 28% in clinical genetics and Q67.40 (Other congenital deformities of the skull, face and jaw, Hemifacial atrophy), 18% in dental, oral and maxillofacial diseases. Of the patients, 70% had had visits in clinical genetics, 60% in plastic surgery, 41% in dental, oral and maxillofacial diseases, 28% in adolescent/adult psychiatry and 21% in child psychiatry. The majority of the patients' plastic surgery visits were concentrated in one university hospital. Other services were mainly provided by patients' own hospital districts. CONCLUSIONS: Even though the majority of CFM patients' visits in specialized healthcare services are related to correction of facial asymmetry and ear malformations, the obvious need for psychiatric care was apparent in all age groups.
