“…The inter canine and inter molar width findings are similar to the findings of other studies (19,22,31) . Another important consideration in arch widths is the tooth size arch length discrepancy (9,22,29) . In the study of Aksu and Kocadereli (20) , there was more crowding in the extraction group than in non extraction group and they found that after extraction treatment the posterior teeth moved mesially into narrower parts of the arch, indicating that anchorage requirement were kept moderate.…”

Aims:To investigate whether extraction status and gender had any significant influence on the maxillary arch dimensions. Materials and Methods: A sample of 40 orthodontic patients (20 extraction and 20 non extraction) were included in this study. Males and females were evenly represented in both groups. All patients were treated with fixed edgewise appliances. Dental casts were taken before and after final orthodontic treatment, fifteen maxillary arch parameters were evaluated at pre-and posttreatment stage and included; dental arch width at the canine, 1 st premolar, 2 nd premolar, 1 st molar (at mesiobuccal and distobuccal cusp tips), arch depth at canine and 1 st molar, arch lengths (incisal canine length, canine molar length and incisal molar length), and arch perimeter. A paired sample t-test was used to evaluate the treatment changes in the extraction and non extraction groups and also to compare between males and females before treatment and after treatment. Results: Generally, in both genders, most pretreatment arch dimensions were not significantly different between extraction and non extraction groups, while after treatment the extraction treatment resulted in the reduction in the arch perimeters, arch depth, and arch length. Where as the non extraction group showed a significant increase in most maxillary arch dimensions. In addition both the extraction and non extraction treatment did not cause narrowing of the dental arch at the canine region. The direction of post treatment changes were similar in male and female subjects. However, the magnitude of the post treatment changes in some parameters differed significantly between females and males particularly in the non extraction group. Conclusions: the extraction and non extraction groups showed similar trend in some maxillary dimensions and different in other dimensions, thus it was concluded that the kind of treatment may affect the maxillary arch dimensions. In addition the non extraction group had a larger number of significant gender differences between females and males than the extraction group.

“…From the data gathered, the measurement of 52mm was used as it is the maximum. The width of the mouth cavity can be referred in Figure 2.3 [9]. The following dental arch width measurements were recorded between reference points of canines, between the first premolars, and between the first molars respectively: upper jaw: men: canines: 35.1 ± 0.13 mm; first premolars: 37.5 ± 0.13 mm; first molars: 48.1 ± 0.19 mm; women: canines: 33.4 ± 0.13 mm; first premolars: 35.6 ± 0.15 mm; first molars: 46.7 ± 0.19 mm [9].…”

Multiple angle of bisector rinn holder is a film holder instrument that is yet to be developed that is able to use paralleling technique and bisecting angle technique in oral x-ray radiography. It is a device aimed to be able to use multiple techniques in oral radiography while getting a good image quality that helps the dentist in doing their work. This is a project that involves the development of the instruments and the effectiveness of the instruments compared to the existing one. The result of the radiographic image was compared and certain constraint was used to compare the instruments with the existing instruments. This project used CATIA V5 software for the design stage. In this project, the instrument was tested to validate the effectiveness where the testing was conducted at the faculty of dentistry. The outcome was the effectiveness of the instrument as compared to the existing instrument with other certain constraints.

“…No entanto existe uma controvérsia na literatura a respeito da ativação do gel com fontes de luz ou calor; sabe-se que a luz degrada mais rapidamente o peróxido e seus componentes reativos (radicais livres de oxigênio), porém apresenta custo mais elevado (DOSTALOVA et al, 2004). Além disso, a potencialização do gel clareador através da temperatura pode causar injúrias ao tecido pulpar (BAIK, RUEGGEBERG, LIEWEHR, 2001;ELDENIZ et al, 2005;REYTO, 1998;SULIEMAN, REES, ADDY, 2006).…”

“…Segundo alguns autores a ativação do gel com fontes de luz ou calor, tem por objetivo aumentar a temperatura do peróxido de hidrogênio, acelerando sua quebra e, conseqüente degradação do peróxido e seus componentes reativos de radicais livres de oxigênio, com a finalidade de melhorar a efetividade da técnica (DOSTALOVA et al, 2004;HATTB;QUDEIMAT;AI-RIMAWI, 1999 (HEIN et al, 2003;MONDELLI, 2003). Esses mecanismos geram um aumento mínimo de temperatura sem dano ao tecido pulpar, já que o comprimento de onda varia de 800 a 900nm, portanto na faixa do infravermelho próximo, levando a um aumento de temperatura pulpar de aproximadamente 3ºC, aquecendo o produto e não a estrutura dental (ARRASTIA et al, 1994).…”
