Debilitating lower back pain during menses unexpectedly resolved after treatment of subclinical temporomandibular disorder: a case report.

This case report describes a patient in whom debilitating lower back pain that always occurred during menses resolved when she received treatment for subclinical temporomandibular disorder (TMD). The patient was diagnosed with subclinical TMD and facial myalgia based on the results of clinical and radiographic examinations. She was treated with maxillary (nighttime) and mandibular (daytime) dental orthotics to provide stabilization and decompression of the temporomandibular joints. After 12 weeks of appliance therapy, which resulted in resolution of the TMD symptoms, the patient reported that the debilitating lower back pain she experienced during menses had ceased. Her back pain did not return after the use of the mandibular appliance was discontinued. The authors discuss how neurologic, postural, inflammatory, and qi flow changes attributed to the patient's TMD treatment may have contributed to the cessation of the patient's menses-related lower back pain.

Nasal patency and mandibular movement: clinical application in prosthodontics.

This case report describes a patient with a primary concern of persistent mandibular deviation during speech who experienced clinically significant improvement (mandibular movement without deviation) after improvements to nasal resistance. At the initial consultation, temporary placement of a nasal valve dilator immediately eliminated the patient's mandibular deviation during speech, indicating the need for referral to an otolaryngologist. The patient was also provided with a dental appliance to address secondary concerns of temporomandibular joint noises and cervicofacial pain. Although the dental treatment provided some relief, resolution of the patient's mandibular deviation during speech did not occur until after nasal surgery was completed. This case illustrates the importance and effects of nasal resistance and nasal patency to obtaining a reproducible mandibular position.

Development and initial validation of a questionnaire to measure patient experience with oral appliance therapy.

STUDY OBJECTIVES: To develop and validate a questionnaire to measure patient experience with oral appliance therapy. METHODS: The AMEE Guide No. 87 was followed in the development and validation of a patient questionnaire to assess patient experience with oral appliance therapy. RESULTS: Our search identified 522 articles; 5 of these articles described the use and/or validation of questionnaires to measure changes in symptoms and patient-reported outcomes in the treatment of obstructive sleep apnea. A total of 27 questions were developed. Five patients participated in pilot testing. A final review of the questionnaire was conducted by an expert panel. CONCLUSIONS: The creation and validation of a questionnaire to assess patient experience with oral appliance therapy may provide new methods for advancing research in the field of dental sleep medicine.

A case study on myofunctional therapy and malocclusions created by oral habits.

Purpose: To demonstrate the effect of an orofacial myofunctional therapy intervention by an interdisciplinary team composed of a registered dental hygienist who is also a certified orofacial myologist (COM®), a general dentist, and an orthodontist on the elimination of oral habits and changes in dental malocclusion. Method: This case study describes a 7-year-old female who underwent an individualized myofunctional therapy program and was given supervised education on a series of exercises targeting the muscles of mastication and facial expression over 5 months. Correct oral rest postures of the tongue and the lips were also established through therapy. Results: The intervention enabled the client to eliminate multiple oral habits, which corrected oral rest postures of the lips and tongue. This correction consequently improved the client's malocclusion and further prepared the client for future orthodontic treatment. Conclusion: Myofunctional therapy facilitated the elimination of unfavourable oral habits that led to malocclusion. Eliminating oral habits better prepared the client for orthodontic treatment and retention. Use of an interdisciplinary team facilitates optimal client care.

Objectif: Démontrer l'effet d'une thérapie orofaciale myofonctionnelle par une équipe interdisciplinaire composée d'un hygiéniste dentaire autorisé qui est aussi un myologiste orofacial certifié (COM®), d'un dentiste généraliste et d'un orthodontiste sur l'élimination des habitudes buccales et les changements de la malocclusion dentaire. Méthodologie: La présente étude de cas décrit une fille de 7 ans qui a suivi un programme personnalisé de thérapie myofonctionnelle et a reçu une éducation supervisée sur une série d'exercices ciblant les muscles de la mastication et de l'expression faciale au cours d'une période de 5 mois. La thérapie a aussi permis d'établir des postures appropriées de repos de la langue et des lèvres. Résultats: Grâce à la thérapie, la cliente a pu éliminer de multiples habitudes buccales, ce qui a corrigé les postures de repos buccal des lèvres et de la langue. Cette modification a par conséquent amélioré la malocclusion de la cliente et a permis de la préparer à un futur traitement orthodontique. Conclusion: La thérapie myofonctionnelle a favorisé l'élimination d'habitudes buccales défavorables qui ont mené à la malocclusion. En éliminant les habitudes buccales, la cliente était mieux préparée au traitement orthodontique et à la rétention. L'utilisation d'une équipe interdisciplinaire optimise les soins du client.

Building a memory palace in minutes: equivalent memory performance using virtual versus conventional environments with the Method of Loci.

The Method of Loci (MOL) is an ancient mnemonic strategy used to enhance serial recall. Traditionally, the MOL is carried out by imagining navigating a familiar environment and "placing" the to-be-remembered items in specific locations. For retrieval, the mnemonist re-imagines walking through the environment, "looking" for those items in order. Here we test a novel MOL method, where participants use a briefly studied virtual environment as the basis for the MOL and applied the strategy to 10 lists of 11 unrelated words. When our virtual environments were used, the MOL was as effective, compared to an uninstructed control group, as the traditional MOL where highly familiar environments were used. Thus, at least for naïve participants, a highly detailed environment does not support substantially better memory for verbal serial lists.
