Maxillary Arch

: In prosthodontics, esthetics a combination of the art and science. Patients requiring complete dentures usually expect comfort first, followed by harmonious appearance, and lastly efficiency. Therefore, the correct selection of the artificial teeth is essential for achieving a pleasant esthetic outcome. A number of soft tissue landmarks have been purported as useful for anterior tooth selection; but these are easily affected by several factors such as aging and the weight and build of the person. In the present study hard tissue landmarks like pterygomaxillary notches and maxillary arch width was presented as alternative anatomical landmark for anterior teeth selection. The aim of the study was to evaluate the hamular width and inter maxillary arch width which could be the guide for the selection ofartificial teeth for complete maxillary denture in the North-East Indian population.The study was conducted on 100 dentate individuals from the North Eastern Indian population, between the age group of 18- 30 years. All measurements were done with digital calliper on cast obtained after impression with irreversible hydrocolloid impression material.Pearson correlation analysis showed, statistically significant correlation between maxillary archwidth and central incisor width. The result was significant at p<0.05 but not high enough to be practically used. Correlation between hamular width and central incisor width was found to be insignificant. The value of R was 0.05435. The result was significant at p < 0.05. The maxillary arch width was in direct proportion to the maxillary central incisor width which meant that the increase of maxillary arch width,there was a corresponding increase of maxillary central incisor width. Significant correlation was found between maxillary arch width and central incisor width with p value=0132. The result was significant at p<0.05 but not high enough to be practically used. But In this study statistically insignificant correlation was found between hamular width and central incisor width.

Β Carotene

In the North Eastern Himalayan region (NEHR) of India, maize is an important food crop. The local people cultivate the maize landraces and consume them as food. However, these landraces are deficient in β-carotene content. Thus, we aimed to incorporate the crtRB1 gene from UMI285β+ into the genetic background of the NEHR maize landrace, Yairipok Chujak (CAUM66), and thereby enhance the β-carotene content through marker-assisted backcrossing (MABC). In this regard, we backcrossed and screened BC1F1 and BC2F1 plants possessing the heterozygous allele for crtRB1 and then screened with 106 polymorphic simple sequence repeat (SSR) markers. The plants having maximum recurrent parent genome recovery (RPGR) were selected in each generation and selfed to produce BC2F2 seeds. In the BC2F2 generation, four plants (CAUM66-54-9-12-2, CAUM66-54-9-12-11, CAUM66-54-9-12-13, and CAUM66-54-9-12-24) having homozygous crtRB1-favorable allele with maximum RPGR (86.74–90.16%) were selected and advanced to BC2F3. The four selected plants were selfed to produce BC2F3 and then evaluated for agronomic traits and β-carotene content. The agronomic performance of the four lines was similar (78.83–99.44%) to that of the recurrent parent, and β-carotene content (7.541–8.711 μg/g) was on par with the donor parent. Our study is the first to improve the β-carotene content in NEHR maize landrace through MABC. The newly developed lines could serve as potential resources to further develop nutrition-rich maize lines and could provide genetic stock for use in breeding programs.
