RESUMO
BACKGROUND: Evidence regarding the etiology or effective treatments for chronic orofacial pain, the majority diagnosed as temporomandibular disorder (TMD), is limited. PURPOSE: To investigate whether occlusal equilibration therapy (ET) and decreasing the (higher) angle of the lateral guidance on the nonworking-side leads to a reduction in chronic TMDs intensity. METHODS: It was conducted a randomized, explanatory, single blind with blinded assessment, placebo-controlled trial with strong protection against bias involving patients with chronic TMDs. Participants were randomly assigned to receive equilibration therapy or sham therapy. ET in this study consisted of minimal invasive occlusal remodeling to obtain balanced occlusion with reduction of the steeper angle of lateral mandibular movement with respect to the Frankfort plane. The primary outcome was a change in the pain intensity score (on a 0-10 point scale, with 0 indicating no pain and 10 the worst possible pain) at month 6. Secondary outcomes include maximum unassisted mouth opening and psychological distress. RESULTS: A total of 77 participants underwent randomization, 39 of whom received ET and 38 sham therapy. The trial was stopped early for efficacy, according to preestablished rules when 67 participants (n = 34, n = 33, respectively) had completed the analysis. At month 6, the mean unadjusted pain intensity score was 2.1 in the ET and 3.6 in the sham therapy group (adjusted mean difference, -1.54; 95% confidence interval [CI] -0.5 to -2.6; P = 0.004; ANCOVA model). The mean increase in maximum unassisted mouth opening (main secondary outcome) was significantly higher in the real therapy group (adjusted mean difference 3.1 mm, 95% CI 0.5-5.7, p = 0.02). CONCLUSION: ET significantly reduced the intensity of facial pain associated with chronic TMDs and increased maximum unassisted mouth opening, as compared with sham therapy, over the course of 6 months. There were no serious adverse events.

RESUMO
Introduction: Oral status has a clear impact on systemic health, a key component of successful aging. Awareness of oral disorders permits early diagnoses and treatments. This study investigates oral disorders awareness among community-dwelling elders. Methods: Community-based survey through face-to-face interviews undertaken in four cities at busy commercial and administrative areas. Results: A total of 789 people were recruited, mostly nonsmoker (60.3%) males (56.9%) with basic education (65.6%). The most frequently recalled disorder was bruxism, followed by periodontal diseases and ulcerations/aphthae. Caries was mentioned by 3.91%. Dentate participants were more aware of dental-related disorders, such as bruxism (p = .001) and periodontitis (p = .010), except for caries (p = .100). Caries awareness was related to educational level (p = .018) and smoking (p = .020), as was oral cancer (p = .019) with former smokers more aware of this neoplasm. Education was strongly related with periodontal awareness (p = .001). Conclusion: Awareness of the main oral disorders is worryingly poor among the elderly population and immediate action is required by taking advantage of the position of family nurses in the treatment of systemic chronic disorders and through educational interventions on this population subgroup to ease preventive behaviors, favor early diagnoses, and promote simpler, more effective treatments with a lower financial burden.

OBJECTIVE: To undertake a meta-analysis of the association of Oral Lichen Planus (OLP) with diabetes, two diseases with an important impact on public health and the economy, but the evidence of which about their association is inconsistent. METHODS: Relevant studies were localized by searching MEDLINE, EMBASE, Conference Proceedings, and other databases from inception to October 2020, without restrictions. The reference lists of included studies and of related reviews were also inspected. Global pooled odds ratios were calculated, and predefined subgroup analyses were performed. The heterogeneity between studies and publication bias was assessed and sensitivity analysis was carried out. RESULTS: Thirty-two studies were included in the meta-analysis. Pooled ORs showed a moderate association between diabetes and OLP [OR: 1.87 (95%CI: 1.57, 2.34)]. The association is limited to studies carried out on adults only [OR: 2.12 (95%CI: 1.75, 2.57)] and is observed in all study designs. Globally, the heterogeneity was low to moderate. Studies carried out in European populations show a stronger association of diabetes and OLP than Asiatic studies [OR: 2.49 (95%CI: 1.87, 3.32) and 1.60 (95%CI: 1.25, 2.03), respectively]. CONCLUSIONS: Diabetes and OLP are moderately associated. Systematic diagnosis of diabetes in OLP patients could prove useful.

OBJECTIVES: To identify the immunohistochemical pattern of non-tumoral epithelium adjacent to lip cancer (ANTE) to unveil molecular alterations and potential biomarkers in lip cancer patients. MATERIALS AND METHODS: A systematic search at MEDLINE, EMBASE and proceedings Web of Science, OpenGrey and WorldCat. The PICOS outline (Population: lip cancer patients; Intervention: immunostaining with biomarkers in surgical specimens; Comparisons: ANTE versus LC; Outcomes: primary-to identify the immunohistochemical pattern of peritumoral epithelium and secondary-to assess the immunoreactivity of LC epithelium; and Study design: cross-sectional, case-control and cohort studies). RESULTS: A total of 339 records were identified. Seven studies reporting on ANTE and LCs were included in the qualitative synthesis, and 4 of them (p53 immunostaining) were selected for meta-analysis. In the ANTE group, the pooled prevalence of p53 was 0.74 (95% CI: 0.66 - 0.82), while in the lip squamous cell carcinoma group this prevalence was 0.83 (95% CI: 0.75 - 0.89). CONCLUSIONS: Similar immunoexpression was found in lip epithelium adjacent to lip carcinoma, even in epithelia with normal appearance or mild histological alterations. The role of biomarkers in the follow-up of actinic cheilitis patients deserves additional clinical assessment.

This investigation was aimed at determining the time intervals from the presenting symptoms until the beginning of oral cancer treatment and their relative contribution to the total time, and to assess the impact of the presenting symptom on diagnostic timelines and patient referral routes. A cross-sectional, ambispective study was designed to investigate symptomatic incident cases. The Aarhus statement was used as a conceptual framework. Strategies for minimizing potential recall biases were implemented. A sample of 181 patients was recruited (power: 99.5%; α = 0.05). The patient interval reached 58.2 days (95% CI, 40.3-76.2), which accounted for 74% of the whole prereferral interval and for more than one third of the total time interval. The presenting symptom (trigger for consultation) influenced both the number of primary care consultations and the length of time to diagnosis. General dental practitioners generated longer intervals to diagnosis (p < 0.005) and needed more consultations before referring a patient (RR = 0.76; 95% CI, 0.61-0.93), than general medical practitioners. The current study identifies the patient as the main target for interventions to improve awareness and reinforces the need for increased alertness amongst healthcare professionals about presenting symptoms of oral cancer and to diminish the number of prereferral consultations in order to optimize the primary care interval.
RESUMO
INTRODUCTION: The etiologies of most chronic temporomandibular joint disorders are unknown. However, an association between habitual chewing on a particular side and chronic temporomandibular joint disorders has been reported. The aim of this study was to investigate the differences between sides (affected vs unaffected) of biodynamic factors (including lateral dental guidance determined by dental anatomy) or condylar path angles (determined by temporomandibular joint morphology) and chewing function (physiological alternate chewing vs single habitual chewing side). The study scope was to investigate possible etiological factors to improve the understanding of temporomandibular joint disorders. The null hypothesis was that no difference would be found between sides that are or are not affected by chronic temporomandibular joint disorders in chewing function or in levels of dental or temporomandibular joint remodeling. METHODS: This cross-sectional, double-blind study involved 24 adults with substantial, chronic, unilateral symptoms diagnosed as temporomandibular joint disorders. Chewing function, temporomandibular joint remodeling (using axiography) and dental anatomy (lateral guidance angles using kinesiography) were assessed. RESULTS: Habitual chewing on one particular side was observed in 17 of 24 participants; significantly more (n=15) chewed on the affected side than on the unaffected side (P=0.002 in a two-tailed Fisher's exact test; risk estimate=4.5; 95% CI 1.326-15.277). The condylar path (CP) angle was steeper on the affected side than on the unaffected side (mean (standard deviation)=50.52° (9.98°) versus 45.50° (7.98°); P=0.002 in a two-tailed t-test). The lateral guidance (LG) angles were flatter on the affected side in all 24 participants. CONCLUSION: Our results suggest that habitual chewing on one side may be associated with increasing condylar path, with flattening lateral guidance angles, and also with chronic temporomandibular joint disorder on the habitual chewing side.

AIMS: To discuss the terminology to define and classify actinic cheilitis (AC) and to build a consensus on the diagnostic and therapeutic approaches to AC. METHODS: Two-round Delphi study using a questionnaire including 34 closed sentences (9 on terminology and taxonomy, 5 on potential for malignant transformation, 12 on diagnostic aspects, 8 on treatment) and 8 open questions. Experts' agreement was rated using a Likert scale (1-7). RESULTS: A consensus was reached on 24 out 34 statements (73.5%) and on 5 out of 8 (62.5%) close-ended questions. The response rate was identical in both rounds (attrition of 0%). AC is the term with the highest agreement (median of 7 (strongly agree; IQR: 6-7)) and the lowest dispersion (VC = 21.33). 'Potentially malignant disorder' was the preferred classification group for AC (median of 7) and 85.6% of participants showing some level of agreement (CV < 50). Experts (66.75%) consider AC a clinical term (median: 7; IQR: 4-7) and believe definitive diagnosis can be made clinically (median: 6; IQR: 5-7), particularly by inspection and palpation (median: 5; IQR: 4-6). Histopathological confirmation is mandatory for the management of AC (median: 5; IQR: 2.5-7), even for homogeneous lesions (median: 5; IQR: 3.5-6). Consensus was reached on all treatment statements (VC < 50). CONCLUSIONS: AC is a potentially malignant disorder with a significant lack of agreement on diagnostic criteria, procedures, biopsy indications and the importance of techniques to assist in biopsy. A consensus was reached on nomenclature and management of this disorder.

This study aimed at assessing the prevalence of alveolar antral artery (AAA) detection by CBCT, its related variables, and at describing explanatory models useful in surgical planning, by retrospective evaluation of CBCT explorations. The modelling of the probability for detecting AAA was undertaken using logistic generalized additive models (GAM). The capacity for discriminating detection/no detection was assessed by receiver operating characteristic curves. A total of 466 sinuses were studied. Univariate models showed detection probability was linked to sinus width and thickness of the lateral bony wall, together with the shape and height of the osseous crest. AAA detection probability increased steadily until the thickness of the bony wall reached 6 mm. Multivariate models resulted good discriminators for AAA detection, particularly for females, showing an area under the curve (AUC) of 0.85. Models considering patients altogether, and those including only males offered slightly lower values (AUC = 0.79). The probability of AAA detection by CBCT was influenced by gender (higher in males and for narrow sinuses) and increases with the thickness of the sinus lateral bony wall and the height of the residual alveolar ridge. Besides, and particularly for women, the thickness of the ridge at the basal level seems to improve the explanatory model for AAA detection.

OBJECTIVES: To assess the impact on survival of the total time interval since the first bodily change (sign/symptom) until the start of treatment in symptomatic oral cancer patients. METHODS: Retrospective, hospital-based study designed within the "Aarhus Statement" conceptual framework, using the overall interval to treatment of 183 oral cancer patients to analyse their survival rates. RESULTS: Overall time interval (T5): 107.1 ± 85.2 days. Overall survival rate: 58.4 (CI: 51.3-66.4%). Recurrence time (median): 724 days (IQR, 223-2963.5). Median survival time: 1744 days (IQR, 479.5-3438). Overall delay (T5) and mortality showed a U-shaped association, where patients with short (24.0-55.5 days) and long T5 intervals (127.5-420 days) had higher mortality than those with medium T5 intervals (55.5-127.5 days). CONCLUSION: There is a non-monotonic association between time interval and mortality. Higher mortality rates are linked to shorter and longer time intervals. This may induce underestimation of the association when time intervals are considered dichotomously.

OBJECTIVE: To describe family nurses self-reported oral hygiene practices and to compare them with those of their potential patients in a public, free, and universal primary healthcare system. MATERIAL AND METHODS: Cross-sectional study using an anonymous questionnaire applied to randomly selected participants and their family nurses. RESULTS: A total of 1,394 people entered the study (1,326 laypersons, 66 nurses). Not all nurses reported to brush their teeth daily. Daily interdental cleaning scored percentages lower than mouthwashes. Devices like oral irrigators or tongue scrappers were not used by family nurses. CONCLUSIONS: Nurses' oral self-care routines are similar to those of university graduates, with poor reported interdental cleaning. Oral health promotion activities may contribute to nurse's oral health and could have a positive effect on their patients.

OBJECTIVES: To explore dental clinics' performance on periodontal education by comparing knowledge about periodontal health of regular and inconsistent dental attenders. SUBJECTS AND METHODS: A population-based study with a cross-sectional design was performed in Galicia (Northwestern Spain). Participants were randomly selected from 16 different areas and a questionnaire applied face-to-face. The survey included items on socio-demographic features, habits and routines, periodontal status and periodontal health knowledge. Participants were grouped according to the median of overall knowledge, and a logistic regression analysis was performed to explore the relationship between good periodontal knowledge and frequency of dental visits. RESULTS: A total of 8,206 individuals were invited to enter the study, and 3,553 of them accepted the invitation (43.3%). Most participants (59.3%; n = 1,945) fit within the regular dental attenders' group. Younger women holding a university degree and visiting their dentist regularly elicited higher knowledge about periodontal health. Regular use of dental services increased the chances of being in the higher knowledge group (OR: 1.67; 95% CI: 1.40-2.00). CONCLUSIONS: Reported regular dental attendance is related to periodontal health knowledge. Specific interventions for promoting tailored patient education on periodontal topics during routine dental visits may have a positive effect on laypersons' knowledge about periodontal health.

BACKGROUND: In early diagnosis studies on symptomatic cancer, survival was the most recommended outcome. The magnitude and impact of the patient interval and primary care interval is well-known in oral cancer; however, the hospital interval and its influence on surviving this neoplasia are not well known. AIMS: To quantify the interval between the first contact with the specialist and the start of treatment for patients with oral cancer and to evaluate whether there was a link between this interval and disease survival. METHODS: We designed a hospital-based study that included 228 patients diagnosed with oral/oropharyngeal squamous cell carcinoma between 1998 and 2008 at A Coruña University Hospital (Spain) who were followed up until 2016. The data were extracted retrospectively from hospital medical charts. The study interval was defined in the context of the "pathways to treatment" model as the interval from the first specialist visit (start point) to the start of treatment (end point). We calculated the total interval (from first symptom to treatment) to evaluate the relative length of the hospital interval, and we considered the variables age, sex, location, comorbidity and tumour classification stage. Survival time was defined as the interval from the first treatment to death or censoring. RESULTS: The median hospital interval was 20 days, with an interquartile range of 15-29.1 days. The most relevant prognostic variable was the tumour stage (III-IV: Exp. ß = 2.8, p = 0.001). The hospital interval was part of the multivariate model, and its association with mortality showed a V-shaped association, where patients with short hospital intervals (3-18 days) and those with long hospital intervals (26-55 days) had significantly higher mortality than those with medium hospital intervals (19-25 days). CONCLUSION: The hospital interval represents a relevant interval for the patient's path towards treatment, has prognostic implications and is subject to a severity bias (waiting time paradox) that should be avoided.

INTRODUCTION: Training on impression disinfection is often limited to brief explanations in the clinic. This investigation assessed knowledge on this topic amongst clinical students in our university, produced a pill of knowledge to suit their needs, and evaluated its impact and acceptance. MATERIAL AND METHODS: A pre-post study was designed to identify knowledge gaps using an anonymous, voluntary self-applied questionnaire before and after watching an audio-visual clip (pill of knowledge). All 136 students in the school were invited to enter the study (estimated sample size: 116). RESULTS: Participants: 109 (26.6% in 3rd year; 37.6% in 4th year and 39.4% in 5th year). Participation dropped 10.29% (n = 95) in the post-intervention survey. Knowledge improvement was higher for those impression materials included in the pill. Most students (68.4%) reported to know more about impression disinfection after the pill and 70.5% felt more able to achieve correct disinfection. The pill was particularly well received (86.3%). All students would recommend it to their peers, and 93.5% are willing to receive pills on other topics. DISCUSSION: Our results disclosed an important gap in knowledge, which can be filled by a single, brief and concise pill adapted to the intended audience. Once made readily available through digital repositories, it may help solve this problem, given the ubiquitous presence of mobile devices. CONCLUSIONS: Our results found pills of knowledge as a useful approach to facilitating undergraduates' learning process. This method, using suitable information and communication technologies, has the potential to improve the performance on certain clinical tasks.

OBJECTIVES: To assess periodontal awareness among laypersons, to characterize the very aware of periodontitis and to disclose whether high awareness implies sufficient periodontal knowledge. SUBJECTS AND METHODS: Cross-sectional study on laypersons randomly selected by quota sampling from March 2015 to June 2016. The questionnaire of periodontal awareness included aspects of aetiology, risk factors, signs and symptoms, related risks, prevention, treatment and related attitudes. It was applied by 12 interviewers in the community in each four province capitals, in a sort of pathfinder survey method. RESULTS: A 43.3% response rate was obtained, and 3,553 people entered the study. "Very aware": 19.4%. "Aware": 42.7%. "Not aware": 37.9%. Age, oral self-care and educational achievements characterized those "very aware." Any additional degree beyond compulsory education halves the chances for being "not periodontally aware." Very aware people likely to have periodontitis were elder, less educated, with a smoking history and less knowledge of the disease. Gaps of knowledge among the "very aware" were identified in all aspects except for "prevention" and "treatment.". CONCLUSIONS: Very periodontally aware people were in their late 40-60 s, followed sound oral care routines and held a degree but elicited insufficient knowledge about aetiology, signs-symptoms, related risks or periodontal risk factors.

BACKGROUND: In this study, the authors assessed the readability of online endodontic information in English and Spanish. METHODS: The authors performed a systematic search in Google in May 2016. Search queries were "root canal treatment" and "¿Qué es una endodoncia?" without limits or filters. The authors assessed English readability by using Flesch-Kincaid Reading Grade Level, Flesch Reading Ease Score, Gunning Fog Index, Coleman-Liau index, automated readability index, and Simple Measure of Gobbledygook (SMOG) index. The authors calculated readability for Spanish by using the Fernández-Huerta index and INFLESZ (Ines-Barrio). RESULTS: The authors assessed the first 100 consecutive sites identified with each search strategy and selected 117 sites. Readability scores for English-language sites were in the category of normal to read, easily understood by 13- through 15-year-old students (Flesch Reading Ease Score, 63, interquartile range (IQR) [53.9-66.2]; Gunning Fog Index, 10.4, IQR [8.8-12]; Coleman-Liau index, 12.5, IQR [11.6-13.3]; and automated readability index, 8.6, IQR [6.7-9.8]). SMOG results led to the estimation that only 7 years of education would be needed to understand these contents (SMOG, 7.6, IQR [6.5-8.8]). Spanish-language sites had a readability index normal for an adult, equivalent to a seventh or eighth school year (Fernandez-Huerta, 62.3, IQR [59.7-66.6]; INFLESZ, 57.5, IQR [55.1-62.1]). The authors found that 36.6% of English-language sites had some degree of difficulty for readers to understand their contents, whereas 23% of Spanish-language sites had some degree of difficulty (14.46; 95% confidence interval, -3.16 to 30.08). CONCLUSIONS: Spanish- and English-language electronic health information about endodontic treatment is acceptable to read, but-particularly for English-language sites-there is an important proportion of sites scoring difficulty levels well above the recommendations. PRACTICAL IMPLICATIONS: The internet is a useful tool for communicating with patients, but available endodontic information is difficult for laypeople to understand. Endodontists should produce relevant materials in plain language to overcome this problem.

Correction of maxillary compression via palatal expansion is easy in children and adolescents, but more complicated once growth is finished. This correction may be performed by progressive expansion using orthopaedic appliances after osteotomy with more stable results, which facilitate a second phase to achieve larger expansions. We present a clinical case treated using a customized device that improves predictability. The stability of the device is ensured by multiple support points with 8 screws that fix it to the palate. Key words:Surgically assisted rapid palatal expansion, stereolithographic model, customized, bone-borne, expansion device.
