In the horse the incisors and maxillary cheek teeth have enamel invaginations called infundibula that penetrate the occlusal surface. The infundibula provide the occlusal surface with additional enamel. These infundibula are filled or partially filled with cementum and normally have a pin-like hole in the center of the occlusal surface of the cementum that generally travels the length of the in...

One hundred seventeen patients with posterior teeth requiring endodontic treatment were studied. Specific clinical findings were recorded, including pulp, vitality, preoperative pain, sensitivity to percussion, and the presence of a periradicular radiolucency. Excluded from the study were teeth with restorations to be maintained, greater than class I mobility, pocket depths > 5 mm, endodontic r...

OBJECTIVES To assess the height of occlusal registration blocks made in dental laboratories compared with recommended dimensions. To relate these dimensions to the height of the blocks after registration of the occlusion. METHODS All occlusal registration blocks received in a complete denture clinic at the Charles Clifford Dental Hospital, Sheffield, over a 1-year period were measured in heig...

A shortened dental arch without posterior occlusal support has been thought to maintain sufficient oral function. The mechanism of occlusal adaptation with a shortened dental arch is unclear. For a better understanding of the effects of molar teeth on brain function, the authors combined experimentally-shortened dental arches and a neuro-imaging technique. Regional cerebral blood volume was mea...

~~Neuromuscular inhibitory effects were monitored in the temporalis and masseter muscles for ten patients with mandibular joint (MJ) syndrome. and ten control subjects with normal occlusions. Analysis of the electromyographic (EMG) silent period in the controls showed no significant difference between durations at median occlusal position, following placement of a maxillary acrylic occlusal spl...

The clinical behavior of Concise and Prisma Shield sealants for pit and fissure was analyzed by clinical/photographic evaluation. A hematoxylin-based staining solution was applied to the occlusal surface 7 days, 18 months, 36 months, and 11 years after the occlusal sealing, thus allowing the sealant material on the surface to be checked. At each analysis time, each occlusal surface was photogra...

The ability of ozone to kill micro-organisms associated with non-cavitated occlusal caries was investigated. The occlusal surfaces were treated with ozone (n = 53) or air (n = 49) for 40 s, and the underlying infected dentine was exposed. There was no significant difference between the number of bacteria recovered from the ozone-treated and the control sites (p > 0.1). Treatment of the exposed ...

This study was conducted to reduce the bias in measured values caused by the thickness of materials used in occlusal examinations. To this end, a silicone impression material for bite force measurement and an experimental model of a simplified stomatognathic system were employed in this study. By means of this experimental model, results showed that the effect of bias toward the posterior arch ...

INTRODUCTION Temporomandibular disorder (TDM) is the most common source of orofacial pain of a non-dental origin. Sleep bruxism is characterized by clenching and/or grinding the teeth during sleep and is involved in the perpetuation of TMD. The aim of the present study was to investigate the effects of massage therapy, conventional occlusal splint therapy and silicone occlusal splint therapy on...
