Defectos bucodentales en personas con síndrome de Down: una prioridad en salud bucal / Oral-dental defects in people with Down's syndrome: a priority in oral health

RESUMEN El síndrome de Down con frecuencia se acompaña de defectos bucodentales que comprometen la función masticatoria y fonatoria del paciente. Las acciones de prevención y promoción de salud bucal, el diagnóstico precoz y seguimiento de estas enfermedades, contribuyen al logro del verdadero enfoque interdisciplinario que demandan estos pacientes, para lograr una plena inclusión social. Se realizó una búsqueda bibliográfica sobre el tema, con el objetivo de estructurar los referentes teóricos relacionados con los principales defectos bucodentales -congénitos y adquiridos- que afectan a la población con síndrome de Down, para lograr la prevención de estos defectos y el incremento de la calidad de vida de los pacientes. Los defectos bucodentales congénitos más frecuentes encontrados en la trisomía 21, fueron la microdoncia, la macroglosia y la erupción dental tardía. La enfermedad periodontal fue el defecto adquirido de mayor presentación, al que se asocian diversos factores de riesgo, muchos modificables. Las intervenciones tempranas en salud bucal pueden incrementar la calidad de vida de los niños y adultos que padecen este trastorno, ayudándolos a lograr un pleno desarrollo como seres humanos (AU).

ABSTRACT Down's syndrome is frequently accompanied by oral-dental defects compromising the masticatory and phonatory function of the patients. Oral health promotion and prevention actions, precocious diagnosis and follow-up of these diseases contribute to achieving the true interdisciplinary approach these patients demand to reach their full social inclusion. A bibliographic search on the theme was carried out, with the objective of structuring the theoretical referents related to the main oral-dental defects -congenital and acquired-, affecting the population with Down's syndrome to reach these defects prevention and increasing these patients' life quality. The congenital oral-dental defects more commonly found in trisomy 21 were microdontia, macroglossia, and delayed tooth eruption. Periodontal disease was more frequently found acquired defect, to which several risk factors are associated, many of them modifiable. Early interventions in oral health may improve the life quality of these children and adults, helping them to achieve a full development as human beings (AU).

Oral manifestations of celiac disease in French children.

Celiac disease (CD) is an immune-mediated systemic disorder caused by ingestion of the gluten found in wheat, rye, and barley. The currently estimated prevalence in children is about 1%. CD is a chronic enteropathy with gastrointestinal manifestations including diarrhea, abdominal distension and weight loss, but extra-intestinal features are increasingly being reported. Dental and oral manifestations such as dental enamel defects (ED), delay in dental eruption, and recurrent aphthous stomatitis (RAS) are well-recognized manifestations of CD. The aim of this study was to compare the frequency of oral manifestations (ED, RAS and delay in dental eruption) on deciduous and permanent teeth between children with CD and a control population. An oral examination was performed on 28 CD children and 59 control children. All children were younger than 12 years old and had deciduous or mixed dentition. CD children had significantly more ED and RAS than the control group (67.9% vs. 33.9% P=0.004 and 50.0% vs. 21.8% P=0.011, respectively). No delay in dental eruption was observed in CD children. ED were mainly grade I and II of Aine's classification (color defects and slight structural defects). ED were more often seen on CD children's deciduous teeth than on permanent teeth (57.1% and 13.6%, respectively; P<0.001). The main teeth affected by ED are the second molar and canines of the deciduous teeth, and the first molar, central incisor, and lateral incisors of the permanent teeth. RAS and ED that were symmetrical in all quadrants and occurred firstly in teeth that mineralize during the first year of life both seem to be signs of CD. Thus, more information for dentists and pediatricians on these oral manifestations should help improve detection of CD.

Late presentation of 'Lemierre's syndrome': how a delay in seeking healthcare and reduced access to routine services resulted in widely disseminated Fusobacterium necrophorum infection during the global COVID-19 pandemic.

The SARS-CoV-2 outbreak has disrupted the delivery of routine healthcare services on a global scale. With many regions suspending the provision of non-essential healthcare services, there is a risk that patients with common treatable illnesses do not receive prompt treatment, leading to more serious and complex presentations at a later date. Lemierre's syndrome is a potentially life-threatening and under-recognised sequela of an oropharyngeal or dental infection. It is characterised by septic embolisation of the gram-negative bacillus Fusobacterium necrophorum to a variety of different organs, most commonly to the lungs. Thrombophlebitis of the internal jugular vein is frequently identified. We describe an atypical case of Lemierre's syndrome involving the brain, liver and lungs following a dental infection in a young male who delayed seeking dental or medical attention due to a lack of routine services and concerns about the SARS-CoV-2 outbreak.

[Controversy on the terminology of cervical lesions on tooth].

Hard tissue defects at cervical site of tooth has been called the wedge-shaped defect in China for a long time. Other terms, abfraction and non-carious cervical lesions have been proposed in early 1990s. These three different terms are reviewed and analyzed in the present article. The author suggests to use the term non-carious cervical lesions to replace the term wedge-shaped defect in China.

Dental management of patients with congestive heart failure before and after implantation of ventricular assist devices: linking the missing protocol.

Objectives: There are no studies that have reviewed the pre- and post-operative dental protocols for the management of congestive heart failure (CHF) patients before and after implantation of the left ventricular assist device (LVAD). The aim of the present study was to review the pre- and post-operative dental protocols reported in indexed literature related to the management of CHF patients before and after implantation of ventricular assist devices (VAD). Design: The addressed focused question was "Is there a protocol for the dental management of end-stage CHF patients before and after VAD implantation?" Indexed databases were searched using various keywords. Letters to the Editor, review articles, and commentaries/expert opinions were excluded. Results: Seven studies were included and processed for data extraction. The number of participants ranged between 1 and 32 individuals, with age ranging between 14 and 66 years. Dental extractions were performed in 5 studies, and in 2 studies scaling and root planing was done for the treatment of periodontal diseases. One study assessed odontogenic infective foci and other lesions of the oral soft and hard tissues as a preoperative protocol. Six of the 7 studies did not report a dental therapeutic protocol, which was followed for the pre and/or post-LVAD implantation. Conclusions: It is recommended that standardized protocols should be adopted that allow the delivery of safe and effective pre- and postoperative dental care to VAD patients. Such protocols may help influence the morbidity and mortality rates and simultaneously improve the overall quality of life in vulnerable patients.

Teeth: Small but Mighty and Mighty Important. A Comprehensive Review of Children's Dental Health for Primary Care Clinicians.

Healthy teeth allow us to eat and stay well-nourished. Although primary care clinicians receive limited training about teeth, given the common nature of dental problems, it is important that they understand and recognize normal and abnormal dental conditions and can implement primary and secondary prevention of dental conditions in their practice. PubMed has been used to search the scientific literature for evidence on the following topics: normal dental development, dental abnormalities, malocclusion, teething, dental caries and related epidemiology and prevention, fluoride, dental injury and its management and prevention; and identification, prevention and treatment of gingivitis and periodontal disease. Literature review relied on randomized controlled trials, meta-analyses, systematic reviews, and Cochrane reviews when relevant and available. Other sources of evidence included cohort and case-control studies. Consensus statements and expert opinion were used when there was a paucity of high-quality research studies. The literature has been synthesized on these topics to make them relevant to pediatric primary care clinicians, and as available, the strength of evidence has been characterized when making clinical recommendations.

Recent developments in equine dentistry.

Equine dentistry is a rapidly developing clinical specialty. It has benefitted from key advances in anatomical and physiological research, development of equipment and instrumentation, utilisation of standing sedation and anaesthesia protocols, a change towards minimally invasive surgical techniques, and the introduction of restorative and endodontic techniques translated from techniques used in human and canine dentistry. Anatomical research has provided further insight into the endodontic system of incisors and cheek teeth and how it changes throughout development with age. Studies of the periodontium have demonstrated a rich vascular supply and repair capacity. Routine dental visits are increasingly being performed utilising sedation and clinical instruments for routine examinations. Equipment has become more efficient, battery-operated and miniaturised giving benefits to both equine dental maintenance work and advanced techniques, assisting the transition to minimally invasive techniques, and the development of endodontic and restorative dentistry. Diagnosis has also benefitted from advances in equipment such as patient-side digital radiography systems, high definition oroscopy, and small diameter flexible fibrescopes that are capable of visualising inside a pulp canal. Dental units combining endodontic high- and low-speed drills, suction and air or water flush are becoming increasingly used and adapted for equine use. Sedative combinations and standing anaesthesia protocols have meant that revisions of traditional techniques, as well as novel techniques, can be performed with almost no requirement for general anaesthesia. Equine dentistry can only continue to advance in this way if there is early identification of dental disease through clinical oral examinations, leading to a system based on prophylaxis, as in human dentistry. This necessitates a change in attitude of the public and industry in general to a proactive approach, with early intervention based on examination and diagnostic findings of practitioners and not necessarily based on the clinical signs displayed by the patient.

Temporomandibular Disorders and Oral Features in Systemic Lupus Erythematosus Patients: An Observational Study of Symptoms and Signs.

Aims: Systemic Lupus Erythematosus (SLE) is a connective tissue disease characterized by a wide range of pleomorphic pictures, including mucocutaneous, renal, musculoskeletal and neurological symptoms. It involves oral tissues, with hyposalivation, tooth decay, gingivitis, angular cheilitis, ulcers and glossitis. Temporomandibular disorders represent a heterogeneous group of inflammatory or degenerative diseases of the stomatognatic system, with algic and/or dysfunctional clinical features involving temporomandibular joint (TMJ) and related masticatory muscles. The aim of this study was to investigate the prevalence of oral manifestations and temporomandibular disorders (TMD) in SLE patients (Lp) compared with a control group. Methods: Fifty-five patients (9 men and 46 women) with diagnosed Lupus were recruited in the study group. A randomly selected group of 55 patients, matched by sex and age, served as control group. The examination for TMD symptoms and signs was based on the standardized Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) through a questionnaire and clinical examination. Results: Lupus patients complained more frequently (95.8%) of oral and TMJ symptoms (dysgeusia, stomatodynia, masticatory muscle pain during function, neck and shoulder muscles pain and presence of tinnitus) but only xerostomia (χ2=4,1548 p=0,0415), temple headache (χ2=4,4542 p=0,035) and the sensation of a stuck jaw (Mid-p-test p=0,043) were significant. About signs, cheilitis (p=0,0284) oral ulcers (χ2=4,0104 p=0,045) and fissured tongue are significantly more frequent in study group. The salivary flow was significantly decreased in the study group respect to the control one (p<0.0001). As regard to the oral kinematics, restricted movements (RM) in protrusion and left lateral movement were significantly different between study group and controls. In particular, 85,2% of Lp showed limited protrusion versus 56,4% of controls (χ2= 10,91 p<0,001); 59,3% of Lp had also a limitation during left lateral movement versus 47,3% of controls (T=2,225 p=0,0282). About bruxism, only the indentations on the lateral edges of the tongue were found in Lp group (72,7%), with a significant difference respect to controls (χ2=7,37 p=0,007). Conclusions: While masticatory muscles have an overlapping behavior in both groups, the findings collected show a more severe TMJ kinematic impairment in Lp than in controls, with protrusion and left lateral movements significantly different. In addition, a remarkable reduction of salivary flow has been detected in Lp compared to controls. In conclusion, this autoimmune disease seems to play a role in oral manifestations and TMJ disorders, causing an increase in orofacial pain and an altered chewing function.

What factors contribute to the self-reported oral health status of Arab adolescents? An assessment using a validated Arabic-WHO tool for child oral health (A-OHAT).

BACKGROUND: The current study was performed; to validate the Arabic version of WHO child oral health assessment tool (A-OHAT), to assess the oral health status of Arab school children and finally to identify the important risk factors associated with the poor teeth and gum conditions of school children. METHODS: A cross-sectional study with two-staged simple random sampling technique was implemented. A-OHAT, a self-assessment tool was subjected to psychometric analyses with the respondents being high school children. The Cronbach's alpha and the Intra class correlation values were computed. Paired t-test was performed to identify the differences between the readings after repeated administration, followed by the analysis for convergent validity. This tested Arabic-WHO Child-OHAT was administered to collect the data. Univariate, bivariate and logistic regression analyses were performed to report on the potential risk factors associated with poor teeth and poor gum conditions of school children. RESULTS: Psychometric analyses revealed that the Arabic Child Oral Health Assessment Tool (A-OHAT) was reliable and valid. A total of 478 (N) high school children were subjected to the tested tool, of which 66.5% were male and 33.5% were female with a mean age of 16.28 + 1.04 years. 80.3% of school children had poor teeth condition and 36.2% of school children had often experienced toothache. Children had 1.5 times higher odds of having poor teeth condition if they had increased frequency of sweet and candy consumption. It was also seen that increased frequency of sweets and candy consumption by school children had put them at nearly 20% higher risk of having poor gum condition. Finally, children with the habit of using toothbrush had nearly 50% lower chance of having poor gum condition in contrast to the school children who do not use toothbrush. CONCLUSION: To conclude, the study provides a reliable and valid tool to assess the oral health status of Arab adolescents. Improper oral hygiene habits and diet were identified as the plausible risk factors for poor teeth and gum condition.

Knowledge and Awareness of Oral Manifestations of Diabetes Mellitus and Oral Health Assessment among Diabetes Mellitus Patients- A Cross Sectional Study.

BACKGROUND AND OBJECTIVES: Diabetes mellitus has increased rapidly throughout the world. The objectives of our study were to assess the knowledge and awareness about oral manifestations of diabetes, among type 2 diabetes mellitus patients, their risk for developing oral diseases due to complications associated with diabetes mellitus, and at same time, to perform an oral examination to detect these oral symptoms, if present any, along with the recording of Decayed Missing Filled Teeth Index (DMFT) and Community Periodontal Index (CPI) index. METHODOLOGY: Structured questionnaires consisting of 12 different statements on the knowledge base of oral manifestations of diabetes mellitus were distributed to 447 Type 2 diabetes mellitus patients. Following this oral examination, brushing and dental visit history were noted, and CPI index and DMFT indices were recorded in all the patients. RESULTS: Results showed that the knowledge about oral manifestations of diabetes mellitus was poor with a mean value of 4.92 out of a possible score of 12. Among the study subjects, the average score of men was 4.42 while that of females, was 5.41. These scores, when subjected to statistical analysis, were highly significant. (P value- 0.005) Subjects also showed significantly high DMFT (P value <0.001) and CPI scores (P value- 0.270). CONCLUSION: Our study concluded that there is a significant lack of knowledge about oral manifestations of diabetes mellitus among patients and hence steps have to be taken to increase their awareness through various outreach programs. All health professionals need to work together for promoting better oral health so that oral complications of diabetes can be brought under control.

School dental screening programmes for oral health.

BACKGROUND: School dental screening refers to visual inspection of children's oral cavity in a school setting followed by making parents aware of their child's current oral health status and treatment needs. Screening at school intends to identify children at an earlier stage than symptomatic disease presentation, hence prompting preventive and therapeutic oral health care for the children. This review evaluates the effectiveness of school dental screening in improving oral health status. It is an update of the original review, which was first published in December 2017. OBJECTIVES: To assess the effectiveness of school dental screening programmes on overall oral health status and use of dental services. SEARCH METHODS: Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 4 March 2019), the Cochrane Central Register of Controlled Trials (CENTRAL, the Cochrane Register of Studies, to 4 March 2019), MEDLINE Ovid (1946 to 4 March 2019), and Embase Ovid (15 September 2016 to 4 March 2019). The US National Institutes of Health Trials Registry (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials. No restrictions were placed on language or publication status when searching the electronic databases; however, the search of Embase was restricted to the last six months due to the Cochrane Centralised Search Project to identify all clinical trials and add them to CENTRAL. SELECTION CRITERIA: We included randomised controlled trials (RCTs) (cluster or parallel) that evaluated school dental screening compared with no intervention or with one type of screening compared with another. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. MAIN RESULTS: We included seven trials (five were cluster-RCTs) with 20,192 children who were 4 to 15 years of age. Trials assessed follow-up periods of three to eight months. Four trials were conducted in the UK, two were based in India and one in the USA. We assessed two trials to be at low risk of bias, two trials to be at high risk of bias and three trials to be at unclear risk of bias.None of the trials had long-term follow-up to ascertain the lasting effects of school dental screening.None of the trials reported the proportion of children with untreated caries or other oral diseases, cost effectiveness or adverse events.Four trials evaluated traditional screening versus no screening. We performed a meta-analysis for the outcome 'dental attendance' and found an inconclusive result with high heterogeneity. The heterogeneity was found to be, in part, due to study design (three cluster-RCTs and one individual-level RCT). Due to the inconsistency, we downgraded the evidence to 'very low certainty' and are unable to draw conclusions about this comparison.Two cluster-RCTs (both four-arm trials) evaluated criteria-based screening versus no screening and showed a pooled effect estimate of RR 1.07 (95% CI 0.99 to 1.16), suggesting a possible benefit for screening (low-certainty evidence). There was no evidence of a difference when criteria-based screening was compared to traditional screening (RR 1.01, 95% CI 0.94 to 1.08) (very low-certainty evidence).In one trial, a specific (personalised) referral letter was compared to a non-specific one. Results favoured the specific referral letter with an effect estimate of RR 1.39 (95% CI 1.09 to 1.77) for attendance at general dentist services and effect estimate of RR 1.90 (95% CI 1.18 to 3.06) for attendance at specialist orthodontist services (low-certainty evidence).One trial compared screening supplemented with motivation to screening alone. Dental attendance was more likely after screening supplemented with motivation, with an effect estimate of RR 3.08 (95% CI 2.57 to 3.71) (low-certainty evidence).Only one trial reported the proportion of children with treated dental caries. This trial evaluated a post screening referral letter based on the common-sense model of self-regulation (a theoretical framework that explains how people understand and respond to threats to their health), with or without a dental information guide, compared to a standard referral letter. The findings were inconclusive. Due to high risk of bias, indirectness and imprecision, we assessed the evidence as very low certainty. AUTHORS' CONCLUSIONS: The trials included in this review evaluated short-term effects of screening. We found very low-certainty evidence that is insufficient to allow us to draw conclusions about whether there is a role for traditional school dental screening in improving dental attendance. For criteria-based screening, we found low-certainty evidence that it may improve dental attendance when compared to no screening. However, when compared to traditional screening, there is no evidence of a difference in dental attendance (very low-certainty evidence).We found low-certainty evidence to conclude that personalised or specific referral letters may improve dental attendance when compared to non-specific counterparts. We also found low-certainty evidence that screening supplemented with motivation (oral health education and offer of free treatment) may improve dental attendance in comparison to screening alone. For children requiring treatment, we found very-low certainty evidence that was inconclusive regarding whether or not a referral letter based on the 'common-sense model of self-regulation' was better than a standard referral letter.We did not find any trials addressing possible adverse effects of school dental screening or evaluating its effectiveness for improving oral health.

Managing tooth pain in general practice.

Tooth pain is a common presentation in primary care, with 32.4% of Singaporeans experiencing pain from dental caries in their lifetime. Some systemic conditions can have oral presentations, and oral conditions may be associated with chronic disease. A good history and examination is key in delineating odontogenic from non-odontogenic causes of tooth pain. Primary care physicians should accurately diagnose and assess common dental conditions and make appropriate referrals to the dentist. Common non-odontogenic causes of orofacial pain can be mostly managed in primary care, but important diagnoses such as acute coronary syndrome, peritonsillar abscess and temporal arteritis must not be missed. Ibuprofen has been shown to be effacious, safe and cost-effective in managing odontogenic pain. Antibiotics are indicated when there is systemic or local spread of dental infection. Without evidence of spread, antibiotics have not been shown to reduce pain or prevent subsequent dental infections.

Predoctoral Dental Education in Tooth Prognosis and Treatment Complexity: A Survey of U.S. Dental Schools.

The aim of this study was to determine the educational methods and tools used to teach tooth prognosis and treatment complexity determination in U.S. predoctoral dental programs. In 2018, an online survey was emailed to the academic deans of all 66 accredited U.S. dental schools. Of these, 42 schools responded (63.6%), and 36 schools completed the entire survey (54.5%). The methods reported for teaching tooth prognosis and case complexity determination varied widely among the participating schools. Among the respondents, 25% reported using the American Association of Endodontists' Endodontic Case Difficulty Assessment, while 10% reported having no specific method for teaching prognosis. The most common method for teaching overall treatment complexity was the Prosthodontic Diagnostic Index, which was used by 24% of the respondents. However, another 24% reported that their school did not have a specific method for teaching treatment complexity. Large percentages of the respondents reported that students sometimes or often made wrong tooth prognosis and case complexity determination (90% and 92%, respectively). The most prominent feedback provided by the respondents based on their experience was the importance of faculty standardization, the understanding of students' inexperience, and the need for an interdisciplinary approach. The majority of these respondents reported that their schools had specific methods of teaching prognosis and case complexity determination. However, there was a wide range of teaching practices related to the contents and levels of evidence.

Orofacial pain and its potential oral causes in older people with mild cognitive impairment or dementia.

BACKGROUND: The number of people with dementia and natural dentition is growing. As dementia progresses, the degree of self-care decreases and the risk of oral health problems and orofacial pain increases. OBJECTIVES: To examine and compare the presence of orofacial pain and its potential causes in older people with Mild Cognitive Impairment (MCI) or dementia. METHODS: In this cross-sectional observational study, the presence of orofacial pain and its potential causes was studied in 348 participants with MCI or dementia with all levels of cognitive impairment in two outpatient memory clinics and ten nursing homes. RESULTS: Orofacial pain was reported by 25.7% of the 179 participants who were considered to present a reliable pain self-report (Mini-Mental State Examination score ≥14 points), while it could not be determined in people with more severe cognitive impairment. The oral health examination of the 348 participants indicated that potential painful conditions, such as coronal caries, root caries, tooth root remnants or ulcers were present in 50.3%. There was a significant correlation between the level of cognitive impairment and the number of teeth, r = 0.185, P = 0.003, teeth with coronal caries, r = -0.238, P < 0.001, and the number of tooth root remnants, r = -0.229, P = 0.004, after adjusting for age. CONCLUSIONS: This study indicated that orofacial pain and its potential causes were frequently present in participants with MCI or dementia. Therefore, a regular oral examination by (oral) healthcare providers in people with MCI or dementia remains imperative, even if no pain is reported.

Protein-Based Salivary Profiles as Novel Biomarkers for Oral Diseases.

The Global Burden of Oral Diseases affects 3.5 billion people worldwide, representing the number of people affected by the burden of untreated dental caries, severe periodontal disease, and edentulism. Thus, much more efforts in terms of diagnostics and treatments must be provided in the fight of these outcomes. In this sense, recently, the study of saliva as biological matrix has been identified as a new landmark initiative in the search of novel and useful biomarkers to prevent and diagnose these conditions. Specifically, saliva is a rich reservoir of different proteins and peptides and accessible due to recent advances in molecular biology and specially in targeted and unbiased proteomics technologies. Nonetheless, emerging barriers are an obstacle to the study of the salivary proteome in an effective way. This review aims at giving an overall perspective of salivary biomarkers identified in several oral diseases by means of molecular biology approaches.

Improving overall health of children living with HIV through an oral health intervention in Cambodia: study protocol for a randomized controlled trial.

BACKGROUND: Currently, the number of children living with HIV is the highest ever. This has led to an increased focus on a healthy life expectancy in this population. Improving oral health status may contribute to improved immunity, which could in turn lead to greater overall health in this population. This study aims to evaluate the effectiveness of an oral health intervention in improving oral health and immune status among children living with HIV in Cambodia. METHODS: A randomized controlled trial will be conducted in Phnom Penh from May 2018 to April 2020. Among 520 dyads of children living with their respective caregivers, half will be randomly allocated to the intervention group and the other half to the control group. Children aged 3-15 years who are currently receiving antiretroviral therapy at the National Pediatric Hospital will be recruited. In addition, 260 HIV-uninfected children (age-matched to the intervention group) will be recruited from the communities. They, together with their caregivers, will comprise the second control group. The main components of the intervention will include oral health education sessions for the children, as well as daily oral self-care under the supervision of their caregivers. The primary study outcome will be the change in oral health status including the number of decayed, missing, or filled permanent teeth, and the secondary outcome will be CD4 count. The effects of the intervention will be assessed by comparing outcome indicators between the children in the intervention and those in the control groups. DISCUSSION: This trial will investigate the effects of an oral health intervention on the improvement of oral health and immune status among children living with HIV and determine the differences compared with the control groups. This intervention would encourage the promotion of oral health interventions among children living with HIV and thus contribute to delaying the onset of AIDS. TRIAL REGISTRATION: Current Controlled Trials, International Standard Randomized Controlled Trial Number Register, ISRCTN15177479 . Registered on 17 January 2018.

Características clínicas orales en pacientes con distrofia muscular de Duchenne: estudio descriptivo / Oral characteristics of patients with Duchenne muscular dystrophy (DMD): descriptive study

Introducción: En su evolución, la DMD afecta el sistema estomatognático, situación no explorada en nuestro país. Objetivo: Describir características clínicas orales y asociación con edad, en pacientes con distrofia muscular de Duchenne (DMD). Pacientes y Método: Estudio descriptivo, transversal en 81 pacientes con DMD del Instituto Teletón Santiago, reclutados desde agosto a noviembre 2017, con consentimiento informado. Se efectuó examen clínico diagnóstico para determinar la presencia de caries clínicas (índice ceod/COPD), índice de higiene (Índice Green y Vermillion Simplificado), presencia de maloclusiones y asociaciones de variables orales con edad. Resultados: 65,4% de los pacientes no presentaban caries ni restauraciones, registrándose un promedio COPD = 1,7 ± 1,2 y ceod= 2,1 ± 1,6. El índice de higiene oral promedio fue de 1,9 ± 0,8 considerado como regular. 67,9% de los pacientes presentaba alguna maloclusión, existiendo una relación esta- dísticamente significativa entre presencia de mordida cruzada y grupo etario (p < 0,05). Conclusiones: La menor presencia de caries clínica en pacientes con DMD a lo referido en bibliografía para pacientes sanos, podría atribuirse a los controles periódicos odontológicos otorgados por Instituto Teletón San- tiago. El aumento de las maloclusiones con el avance de la edad, podría ser un indicador del progreso de la enfermedad, ya que los cambios en la función muscular masticatoria son dependientes del tiempo y producen aumento del ancho transversal mandibular originando las maloclusiones más prevalentes como la mordida cruzada y abierta. Palabras clave: Distrofia muscular Duchenne, caries, higiene oral, malo- clusiones.

Oral characteristics of patients with Duchenne muscular dystrophy (DMD). Descriptive study Introduction: In its evolution, Duchenne muscular dystrophy (DMD) affects the stomatognathic system, a condition that has not been studied in our country. Objective: To describe the oral clinical characteristics and age-related association in patients with DMD. Patiens and Method: Cross-sectional des- criptive study including 81 patients with DMD of Instituto Teletón Santiago, recruited from August to November 2017, with informed consent. A diagnostic clinical examination was performed to establish the presence of clinical cavities (DEFT, DMFT index), oral hygiene index (Green and Vermillion, simplified), presence of malocclusions, and age-related associations. Results: 65.4% of patients did not have caries or restorations, showing an average of DMFT = 1.7 ± 1.2, and DEFT= 2.1 ± 1.6. Average oral hygiene index was 1.9 ± 0.8.which is considered regular. 67.9% of the patients had some type of malocclusion, with a statistically significant relation between the presence of cross bite and age group (p < 0.05). Conclusions: Lower presence of clinical caries in DMD patients as referred to in bibliography for healthy patients, could be due to periodic dental controls provided by Instituto Teletón Santiago. Increased ca- ses of malocclusions with age may be an indicator of progress of the disease, because changes in the function of mastication muscles are time-dependent, and increase transverse jaw width, causing more prevalent malocclusions such as cross bite and open bite. Key words: Duchenne muscular dystrophy, caries, oral hygiene, malocclu- sions.
