Estudio Comparativo de Ansiedad y Disfunción Temporomandibular en Cirujanos Dentistas Residentes de dos Universidades Mexicanas / Comparative Study of Anxiety and Temporomandibular Dysfunctio in Resident Dental Surgeons of Two Mexican Universities

RESUMEN: La ansiedad puede ser un detonante de la disfunción temporomandibular (DTM). Se ha mencionado que el trastorno psicológico más frecuente en México es la "ansiedad" con 14,3 %. El objetivo es correlacionar y comparar los niveles de ansiedad y los grados de DTM en cirujanos dentistas residentes (CDR) de dos universidades mexicanas: la Facultad de Odontología de la Universidad de la Salle Bajío León, Guanajuato (FOULSB), y de la Facultad de Odontología de la Universidad Autónoma (FOUADY) de Yucatán México durante el periodo de septiembre 2017 a febrero 2018. El tipo de estudio fue correlacional, comparativo de cohorte transversal, siendo las variables: ansiedad (niveles según cuestionario de autoevaluación de ansiedad estado/rasgo STAI); signos y síntomas clínicos para el diagnóstico de DTM, (CDI/TTM Grupo I Desórdenes Musculares; Grupo II Desplazamientos discales; Grupo III Artralgia, osteoartritis). El tamaño de la muestra y criterios de inclusión en ambas universidades fueron: CDR en Odontología; que aceptaron participar en el estudio, mediante la firma del consentimiento informado y voluntario; hombres y mujeres; entre 25 a 34 años de edad. Criterios de exclusión: con tratamientos ortodónticos, quirúrgicos, enfermedades sistémicas o neurológicas y que sólo el día que se tomó la muestra presentaron otalgia o cefalea. El tipo de muestreo, por conveniencia. Se utilizó estadística descriptiva e inferencial. Los resultados: 40 CDR de la FOULSB, donde el 92,5 % (n=37) manifestaron tener niveles de ansiedad bajos, y el 7,5 % (n=3) moderado. El 65,8 % (n=26) presentó diagnóstico de DTM. De los 40 CDR de la FOUADY, 97,5 % (n=39) declararon tener niveles de ansiedad bajos, y el 2,5 % (n=1) obtuvo un nivel alto. El 67,5 % (n=27) presentaron signos y/o síntomas de DTM. La conclusión fue que no existieron diferencias estadísticamente significativas, ya que los CDR de ambas universidades presentaron porcentajes de DTM similares y también tuvieron niveles de ansiedad similares.

ABSTRACT: Anxiety can be a trigger for temporomandibular dysfunction (TMD). It has been mentioned that the most frequent psychological disorder in Mexico is "anxiety" with 14.3 %. The objective is to correlate and compare the levels of anxiety and the degrees of TMD in resident dentists (CDR) of two Mexican universities: the Faculty of Dentistry of the University of La Salle Bajío León, Guanajuato (FOULSB), and the Faculty of Dentistry. Dentistry of the Autonomous University (FOUADY) of Yucatan Mexico during the period from September 2017 to February 2018. The type of study was correlational, comparative crosssectional cohort, the variables being: anxiety (levels according to questionnaire self-assessment of anxiety state / trait STAI); clinical signs and symptoms for the diagnosis of TMD, (CDI / TTM Group I Muscle Disorders, Group II Displacement discs, Group III Arthralgia, osteoarthritis). The size of the sample and inclusion criteria in both universities were CDR in Dentistry; who agreed to participate in the study, by signing the informed and voluntary consent; men and women; between 25 to 34 years of age. Exclusion criteria: with orthodontic, surgical treatments, systemic or neurological diseases and that only the day the sample was taken showed otalgia or headache. The type of sampling, for convenience. Descriptive and inferential statistics were used. The results: 40 CDR of FOULSB, where 92.5 % (n = 37) reported having low anxiety levels, and 7.5 % (n = 3) moderate. Sixty-five point eight percent (n=26) presented diagnosis of TMD. Of the 40 CDRs of FOUADY, 97.5 % (n = 39) reported having low anxiety levels, and 2.5 % (n = 1) had a high level. Sixtyseven point five percent (n=27) presented signs and / or symptoms of TMD. The conclusion was that there were no statistically significant differences, since the CDRs of both universities presented similar DTM percentages and had similar levels of anxiety.

The National Dental Practice-Based Research Network Adult Anterior Open Bite Study: Treatment recommendations and their association with patient and practitioner characteristics.

INTRODUCTION: This aim of this paper is to describe and identify the practitioner and patient characteristics that are associated with treatment recommendations for adult anterior open bite patients across the United States. METHODS: Practitioners and patients were recruited within the framework of the National Dental Practice-Based Research Network. Practitioners were asked about their demographic characteristics and their treatment recommendations for these patients. The practitioners also reported on their patients' dentofacial characteristics and provided initial cephalometric scans and intraoral photographs. Patients were asked about their demographic characteristics, previous orthodontic treatment, and goals for treatment. Four main treatment groups were evaluated: aligners, fixed appliances, temporary anchorage devices (TADs), and orthognathic surgery. Extractions were also investigated. Predictive multivariable models were created comparing various categories of treatment as well as extraction/nonextraction decisions. RESULTS: Ninety-one practitioners (mostly orthodontists) and 347 patients were recruited from October 2015 to December 2016. Increased aligner recommendations were associated with white and Asian patients, the presence of tongue habits, and female practitioners. TADs were recommended more often in academic settings. Recommendations for orthognathic surgery were associated with demographic factors, such as availability of insurance coverage and practitioner race/ethnicity, and dentofacial characteristics, such as anteroposterior discrepancies, more severe open bites, and steeper mandibular plane angles. Extraction recommendations were largely associated with severe crowding and incisor proclination. CONCLUSIONS: Both doctor and patient demographic factors, as well as dentofacial characteristics, were significantly associated with treatment recommendations for adult anterior open bite patients.

The National Dental Practice-Based Research Network adult anterior open bite study: A description of the practitioners and patients.

OBJECTIVES:: To describe the demographic and practice characteristics of the clinicians enrolled in a large, prospective cohort study examining recommendations and treatment for adult anterior open bite (AOB) and the relationship between these characteristics and practitioners' self-reported treatment preferences. The characteristics of the AOB patients recruited were also described. MATERIALS AND METHODS:: Practitioners were recruited from the National Dental Practice-Based Research Network. Participants in the study consisted of practitioners and their adult AOB patients in active treatment. Upon enrollment, practitioners completed questionnaires enquiring about demographics, treatment preferences for adult AOB patients, and treatment recommendations for each patient. Patients completed questionnaires on demographics and factors related to treatment. RESULTS:: Ninety-one practitioners and 347 patients were recruited. Demographic characteristics of recruited orthodontists were similar to those of American Association of Orthodontists members. The great majority of practitioners reported using fixed appliances and elastics frequently for adult AOB patients. Only a third of practitioners reported using aligners frequently for adult AOB patients, and 10% to 13% frequently recommended temporary anchorage devices (TADs) or orthognathic surgery. Seventy-four percent of the patients were female, and the mean age was 31.4 years. The mean pretreatment overbite was -2.4 mm, and the mean mandibular plane angle was 38.8°. Almost 40% of patients had undergone orthodontic treatment previously. CONCLUSIONS:: This article presents the demographic data for 91 doctors and 347 adult AOB patients, as well as the practitioners' self-reported treatment preferences.

Management of the Maxillary Diastema by Various Dental Specialties.

PURPOSE: There is considerable controversy in the literature concerning the indications for frenectomy for treating a maxillary diastema and for timing of the procedure. The purpose of this study was to survey pediatric dentists, orthodontists, and oral and maxillofacial surgeons on their opinion of this matter to develop a consensus. MATERIALS AND METHODS: An anonymous 7-item electronic questionnaire was sent to members of the American Academy of Pediatric Dentists, the American Association of Orthodontists, and the American Association of Oral and Maxillofacial Surgeons asking about the etiology of the maxillary diastema, its diagnosis, and treatment. RESULTS: Although there was no agreement among the oral and maxillofacial surgeons for the timing of frenectomy and when the diastema should be closed, the pediatric dentists and orthodontists generally agreed that frenectomy should not be performed before the permanent canines are erupted and that the operation should follow orthodontic closure of the space. CONCLUSION: Although there was no complete consensus among the 3 groups, a logical treatment approach for the maxillary diastema is proposed.

Long-term Evaluation of Treatment Planning Decisions for Nonhealing Endodontic Cases by Different Groups of Practitioners.

INTRODUCTION: The aim of this study was to investigate changes in treatment planning decisions among different practitioner groups over 7 years for teeth with apical periodontitis and a history of endodontic treatment. METHODS: A Web-based survey was sent to dentists in Pennsylvania in 2009 consisting of 14 cases with nonhealing periapical lesions and intact restorations without evidence of recurrent caries. Participants selected among 5 treatment options: wait and observe, nonsurgical retreatment (NSRTX), surgical retreatment (SRTX), extraction and fixed partial denture, or extraction and implant (EXIMP). In 2016, the identical survey was resent to the original 2009 participants. RESULTS: In 2009, 262 dentists participated in the survey. Two hundred one participants were general practitioners (GPs: 76.7%), 26 endodontists (ENDOs: 9.9%), and 35 other specialists (prosthodontics, periodontics, and oral surgery [SPECs]: 13.4%) (n = 262). EXIMP, NSRTX, and SRTX were fairly equally selected but with great variation between practitioner groups (χ2 = 173.49, P < .05). A subset group of 104 participants (SUB) (39.7% of the original participants) retook the survey in 2016 (69 GPs [66.3%], 15 ENDOs [14.0%], and 20 SPECs [19.7%]). Comparisons among practitioner groups were significantly different in SUB (n = 104) for 2009 (χ2 = 95.536, P < .05) and 2016 (χ2 = 109.8889, P < .05). Intragroup reliability between 2009 and 2016 revealed no significant differences between the overall treatment planning choices for all practitioners (GPs, ENDOs, or SPECs). Intrapractitioner reliability showed many treatment planning decision changes on an individual level. Chances that individuals changed their original decision were 47.8% (95% confidence interval, 45.2%-50.4%) and were significantly different among the 3 practitioner groups (GPs > SPECs > ENDOs [χ2 = 11.2792, P < .05]). No significant changes were observed in the decision for tooth saving versus replacement treatment options (P = .520). CONCLUSIONS: No significant differences were noted between current and past treatment planning decisions in regard to tooth preservation by endodontic retreatment versus tooth extraction and replacement. However, individual practitioners lacked consistency in their decision making over time.

Perception, knowledge and attitudes of Brazilian orthodontists on the treatment of Class II malocclusions

ABSTRACT The present study aimed to assess the perception and knowledge of Brazilian orthodontists on the ideal moment to treat Class II malocclusions. Questionnaires with open, semi-open and close questions were sent by e-mail to 1653 Brazilian orthodontists. These orthodontists were registered in the Brazilian Association of Orthodontics and Dentofacial Orthopedics (ABOR). One-hundred and three (9.86%) Orthodontists replied to the questionnaires. Most of them were males (60.5%) with specialization as the highest level of professional qualification (59.9%). Most of the orthodontists (51%) reported preference for treating Class II malocclusions in late mixed dentition, followed by the early mixed dentition (29%). The age range between 10 and 12 years old figured as the most prevalent in patients searching for treatment (42.7%). Most of the patients searching for treatment were females (69.7%). Preferences for functional orthopedic appliances were reported by 35% of the orthodontists. Brazilian orthodontists revealed a trend for treating patients with Class II malocclusions in the late mixed dentition. Female patients aged from 10 to 12 years old represented the majority of patients that search for orthodontic treatment. Functional orthopedic appliances were preferred by Brazilian orthodontists for treating Class II malocclusions.

Accuracy and reliability of orthodontists using cone-beam computerized tomography for assessment of adenoid hypertrophy.

INTRODUCTION: Our objectives were to evaluate the reliability of agreement between orthodontists, with various degrees of cone-beam computed tomography (CBCT) imaging manipulation comfort, in classifying adenoid hypertrophy through CBCT generated images and also to determine how accurate orthodontists are compared with the gold standard diagnosis, nasopharyngoscopy. METHODS: This was a cross-sectional study in which a randomized list of board-certified orthodontists evaluated different degrees of adenoid hypertrophy of a stratified sampling of 10 scans. The available pool of CBCT images was from a multidisciplinary airway clinic in which children and adolescents had a CBCT scan and a nasopharyngoscopy (reference standard) by an otolaryngologist (head and neck surgeon) on the same day. The participating orthodontists used the same viewer software and computer, and had access to a previously published visual guideline for evaluating adenoid size. RESULTS: Fourteen orthodontists evaluated 10 CBCT reconstructions. Interoperator reliability was excellent (intraclass correlation coefficient [ICC], 0.941; 95% confidence interval, 0.882-0.984). However, the orthodontists' evaluations against the reference standard demonstrated poor accuracy, (ICC mean, 0.39; ICC range, 0.0-0.74). Dichotomous data representing healthy and unhealthy patients were analyzed individually, and the orthodontists' evaluations and the nasopharyngoscopy results (accuracy) showed, on average, poor kappa values (mean, 0.44; range, 0.20-0.80). CONCLUSIONS: Different levels of CBCT expertise impacted the assessment accuracy. The participating orthodontists showed excellent consistency among themselves; however, poor agreement between their CBCT assessments compared with nasopharyngoscopy demonstrated that this sample of clinical orthodontists had poor diagnostic accuracy. Together, these findings suggest that orthodontists may make consistent and systematic errors in this type of evaluations.
