A Cross-Sectional Study of Labial Bone and Covering Soft Tissue in Maxillary Anterior Segment: A Dilemma in Orthodontics.

Purposes: The thickness of the buccal bone and its covering gingiva is pivotal in determining the prognosis of implant therapy as well as fixed orthodontic appliances, especially nonextraction treatments. The purpose of this study was to evaluate the buccal bone thickness and covering soft tissue in the maxillary anterior segment.

Methods: This study measured the hard tissue thickness at 2 and 5 mm more apical from the crest and at the root apical apex, as well as the distance from the CEJ to the alveolar crest, using 80 CBCT images divided into three age groups.

Effects of Azocompost and urea on the herbage yield and contents and compositions of essential oils from two genotypes of dragonhead (Dracocephalum moldavica L.) in two regions of Iran.

Dragonhead is an annual, herbaceous, balm-scented and spicy aromatic member of the family Lamiaceae. We examined effects of different sources of nitrogen on the content and composition of essential oils in two genotypes of dragonhead in two regions of Iran. The sources of nitrogen used were 100% urea (70 kg N ha(-1)), 75% urea (52.

Effect of auxin and salt stress (NaCl) on seed germination of wheat cultivars (Triticum aestivum L.).

Seeds of three wheat (Triticum aestivum L.) cultivars included Mahdavi, Pishtaz and Shiraz, were used to investigate the effects of different salinity and auxin concentrations on their germination percent, radicle and hypocotyl length, seedling fresh and dry weight, radicle and hypocotyl dry weight. Results showed that increasing concentrations of NaCl reduced germination percentage, radicle length, hypocotyl length, seedling fresh and dry weight and hypocotyl dry weight.
