Correlation between the distance of maxillary central incisors and incisive papilla in different arch form

In edentulous treatment, relocation of anterior teeth in the preexisting natural position is the utmost importance. It is necessary to refer to the significant anatomical landmarks, one of them is incisive papilla. To make it more efficient both functionally and biologically, the teeth were arranged in particular geometric manner known as a dental arch. The author has chosen to conducted the research among the Malay race represented by the Malay undergraduate students. The purpose of this study was to evaluate the correlation between the distance of maxillary central incisors and incisive papilla (CI-IP) in different arch form and gender. Maxillary impressions of 34 dentate individuals were taken, and the measurements were performed using a digital caliper. The results showed the CI-IP distance was ranging between 7.65 to 9.90 mm, with the average of 8.77 mm. There was no significant difference of the CI-IP distance between male and female regardless of their arch forms (p>0.05). Individuals with ovoid and tapered arch form, however, showed a significant difference of the CI-IP distance between male and female (p<0.05). Meanwhile, Individuals with square arch form showed no significant difference of the CI-IP distance between male and female (p>0.05). It can be concluded that gender factor was irrelevant towards the CI-IP distance regardless of the individual arch form. However, there was a correlation between the CI-IP distance in different arch forms in both male and female sample.

Kebiasaan postur tubuh yang buruk yang mengganggu kesehatan sendi temporomandibula Bad posture habits that interfere with health of temporomandibular joint

Temporomandibular joint (TMJ) is a component of the stomatognati system that supports oral dental health which their components are closely interconnected. Posture is a habit that often do not realize that could cause an imbalance in the joints and muscles, which in turn causes pain. Inadequate body posture can occur on sleep position, lying down, sitting, walking, and other daily activities. Most people are not aware of the dangers of these habits. Dentists are expected to shed some light on the habits of this particular posture errors, which if not promptly removed, it will cause interference with stomatognati systems, such as joint and muscle pain, headache and neck. Complaints due to bad habits can be reduced significantly by eliminating the habit. So it is with the wrong posture habits. With improved posture and a series of exercises as well as the care, the health of TMJ can return to normal with minimal costs. This paper will put forward any posture that can lead to disruption of TMJ.

Ligamen periodontal sebagai pendukung gaya kunyah Periodontal ligament acts to support mastication force

Support for removable partial denture (RPD) can be obtained from bone supported mucosa and or from periodontal ligament of tooth. Support can also be obtained from implant. Tooth support (periodontal ligament) is better than mucosal support because histologically, anatomically, and also physiologically, in addition, periodontal ligament acts to resist mastication force.
