Juvenile Dermatomyositis - A Case Report With Review On Oral Manifestations And Oral Health Considerations, Pritesh Ruparelia, Oshin Verma, Vrutti Shah, Krishna Shah
International Journal of Orofacial Myology and Myofunctional Therapy
Juvenile Dermatomyositis is the most common inflammatory myositis in children, distinguished by proximal muscle weakness, a characteristic rash and Gottron’s papules. The oral lesions most commonly manifest as diffuse stomatitis and pharyngitis with halitosis. We report a case of an 8 year old male with proximal muscle weakness of all four limbs, rash, Gottron’s papules and oral manifestations. Oral health professionals must be aware of the extraoral and intraoral findings of this rare, but potentially life threatening autoimmune disease of childhood, for early diagnosis, treatment, prevention of long-term complications and to improve the prognosis and hence, the quality of life …

Examining The Effects Of Ankyloglossia On Swallowing Function, Kliss Moulton, John Anthony Seikel, Joni Grey Loftin, Nancy Devine
International Journal of Orofacial Myology and Myofunctional Therapy
Oropharyngeal dysphagia (OPD) involves difficulty during one or more of the stages of swallowing, resulting in difficulty moving the bolus from the mouth to the stomach. A deficit in tongue mobility, such as that found with ankyloglossia, may affect the oropharyngeal transit time of the bolus and predispose a person to OPD. This study was conducted to examine the possible relationship between tongue tie and oropharyngeal dysphagia. Data were gathered on 8 participants (5 females, 3 males) between the ages of 12-43 years. The Lingual Frenulum Protocol (Marchesan, 2012) was used to determine tongue tie. An Iowa Oral Performance Instrument …
