clonazepam and Bruxism, Nocturnal

clonazepam has been researched along with Bruxism, Nocturnal in 4 studies

Clonazepam: An anticonvulsant used for several types of seizures, including myotonic or atonic seizures, photosensitive epilepsy, and absence seizures, although tolerance may develop. It is seldom effective in generalized tonic-clonic or partial seizures. The mechanism of action appears to involve the enhancement of GAMMA-AMINOBUTYRIC ACID receptor responses.
clonazepam : 1,3-Dihydro-2H-1,4-benzodiazepin-2-one in which the hydrogens at positions 5 and 7 are substituted by 2-chlorophenyl and nitro groups, respectively. It is used in the treatment of all types of epilepsy and seizures, as well as myoclonus and associated abnormal movements, and panic disorders. However, its use can be limited by the development of tolerance and by sedation.

Fabrication Efficacy -- Retention Trials Week 1

Number of times splint was dislodged while performing eight different movements, with each movement being performed five times (maximum number therefore = 40). Dislodgement meant that, after performing the movement, the splint either fell off the teeth completely or that biting down on the splint resulted in its being reseated on the teeth. (NCT02340663)

Functional Efficacy -- Tooth Wear

Tooth wear measured in millimeters. The number is negative to reflect the amount lost, e.g., -0.1 = a tenth of a millimeter lost. High-resolution, computer-scanned models of the teeth in the lower jaw on the delivery data were combined with high-resolution, computer-scanned models of the same teeth and jaw after 4 months of splint wear. Sites where teeth showed cratering due to dentin exposure were targeted to make these measurements. Changes in these areas was quantified using a computer program designed to quantify differences between two computer models. The measurement represents the difference between the two models, defined by a mean value sampled from a standard-sized area, which was set to be about the size of dentin exposure areas (~ 1 millimeter in diameter). Group means were compared with t-tests. (NCT02340663)

Number of Bruxing Events Per Hour Sleep Per Night.

Polysomnographic monitors were used to evaluate masticatory muscle activity during sleep. Activity of jaw closing muscles found in the cheeks (masseter muscles) occur in bursts, where a burst is taken as evidence for a jaw clench. The total number of bursts recorded during the night was tabulated and then divided by the total hours of sleep. Means presented are based on data gathered on night 122 (4 months of splint wear) and compared with ANOVA. (NCT02340663)

Splint Material Loss / 4 Months.

Splint wear measured in millimeters. The number is negative to reflect the amount lost, e.g., -0.1 = a tenth of a millimeter lost. High-resolution, computer-scanned models of the splint on the delivery date were combined with high-resolution, computer-scanned models of the same splint after 4 months of wear. Sites where teeth contacted the splints were identified, and material loss in these areas was quantified using a computer program designed to quantify differences between two computer models. The measurement represents the difference between the two models, defined by a mean value sampled from a standard-sized area, which was set to be about the size of a tooth cusp (~ 3 millimeters in diameter). Group means were compared with t-tests. (NCT02340663)

Fabrication Efficacy -- Oral Health Modified Gingival Index

Gums or gingiva around each tooth is quantified for absence of inflammation (0), mild inflammation around part of the gingiva next to the tooth (1), mild inflammation involving all of the gingiva next to the tooth (2), moderate inflammation (3), or severe inflammation (4). Average scores are created for the cheek side of the upper teeth (Buccal Upper), palate side of upper teeth (Lingual Upper), cheek side of lower teeth (Buccal Lower) and tongue side of lower teeth (Lingual Lower). Mean and standard deviation scores for each of these regions and for week 1 and month 4 are shown as descriptive statistics; statistical results for the between-subject effects are reported. Overall means for each treatment group (SOVA and Michigan splints) are also reported. (NCT02340663)

Fabrication Efficacy -- Oral Health Plaque Index

The Rustogi et al. Modification of the Navy Plaque Index method of scoring plaque was used. This involves dividing the cheek-facing (Buccal) and the tongue/palate-facing (Lingual) surfaces of each tooth into 9 regions and scoring whether disclosed plaque is present (1) or absent (0) in each of these 9 regions. The total number of regions with plaque was then tabulated as the proportion of total regions for four mouth areas, viz., the cheek sides of the upper teeth (Buccal Upper), the cheek sides of the lower teeth (Buccal Lower), the palate sides of the upper teeth (Lingual Upper) and the tongue sides of the lower teeth (Lingual Lower). Overall means for each treatment group (SOVA and Michigan splints) are also reported. (NCT02340663)
