Nasomaxillary defects may affect patients' speech, mastication, swallowing, breathing, quality of life, psychology, and social behavior. A combination of surgical reconstruction and prosthetic rehabilitation is frequently required to restore optimal function and esthetics. Of particular concern are the size, weight and contour of the prosthesis, as they can drastically affect comfort, retention, masticatory function and ease of insertion and removal. This clinical case report describes the prosthodontic rehabilitation of a partially edentulous patient with a nasomaxillary defect (Aramany class VI) with a two-component prosthesis joined by magnets.The jaw plasmacytoma is a very rare condition, which its diagnosis is difficult in clinical routine. Up to now, less than 60 cases of jaw plasmacytoma have been reported in the literature. In the present case report, we reported a rare case of jaw plasmacytoma in a 42-year-old female, which was misdiagnosed with dental granuloma and abscess. The diagnosis of plasmacytoma was done by immunohistochemistry (IHC) evaluation following a cone beam computed tomography (CBCT) assessment. The patient was treated with radiotherapy and is disease free after 2 years.
The oral health reform plan has been added to the Iran's health reform plan since the beginning of 2015. Evaluation of Iran's oral health reform plan has rarely been conducted.
The aim of this study was to evaluate the change in DMFT among the six-grade primary school children of the city of Shiraz, two years after implementation of oral health reform plan.
A repeated cross-sectional study was conducted on six-grade primary school children of Shiraz in 2015 and 2017. About four hundred children were selected each year by cluster randomization sampling. The schools were randomly selected from three socioeconomically different types of schools including private schools, state schools in affluent areas, and state schools in deprived areas. The DMFT Index of selected children was compared between 2015 and 2017, and among three socioeconomically different areas. One-way ANOVA and Poisson regression tests were used for statistical analysis.
The mean DMFT of children was 1.47±1.83 in 2015 and 1.29±1.79 in 2017. There was significant difference in mean DMFT value between years 2015 and 2017 (
= 0.048). The percentage of children with untreated dental caries was 46% and 36.7% in 2015 and 2017 respectively. There was no statistically difference in DMFT of the three socioeconomically different schools.
There has been significant improvement in DMFT of sixth grade school children of Shiraz two years after implementation of oral health reform plan.

Autogenous bone graft is the gold standard for bone reconstruction. Osteogenic cells must be kept viable in graft for a successful procedure. In extracorporeal preservation of grafts during surgery, three different factors may influence the quality of grafts. These factors include temperature, storage medium, and time interval.
In this study, we evaluated the effects of different storage media, temperatures, and times on osteoblast count in autogenous bone grafts, preserved extracorporeally.
Samples were obtained from iliac crest region in a goat. The grafts were preserved in 36 groups of different storage time, temperature, and medium. Samples were histomorphometrically analyzed to determine osteoblast count as the criteria of graft quality.
In almost all samples, room temperature was the most and incubator was the least favorable storage temperatures. In grafts preserved in room temperature, no difference was noted between normal saline and Ringer's lactate solution and in almost all of the samples autologous blood and dry environment were more favorable media than Ringer's lactate solution. The effect of storage time was highly depended on the combination of temperature and solution.
The results demonstrated that for preserving as many osteoblasts as possible in bone grafts, the best temperature was room temperature and the least favorable temperature was incubator. In addition, when bone fragments were preserved in room temperature, the best medium for graft storage was blood, which showed better results than normal saline and Ringer's lactate solution.

A thorough knowledge of the morphological and anatomical variations of root canal system can help identify all root canals, adequate instrumentation, and consequently leads to a successful endodontic treatment. The knowledge of root morphology can influence the outcome of root canal therapy.
The aim of this study was to investigate the morphology of maxillary premolar canals in Iranian population by analyzing cone-beam computed tomography (CBCT) scans.
This cross-sectional retrospective study consisted of CBCT of 280 patients over 16 years of age. The position, number of roots, and root morphology of maxillary premolars were inspected. The root canal configurations of maxillary premolar teeth were also analyzed according to the Vertucci classification. The statistical analyses wee performed using chi-square test. Significance level was set at
< 0.05.
In the present study, of 462 maxillary first premolars, 8 (1.73%) teeth had three roots, 222 (48.05%) teeth had two roots, and 232 (50.22%) were si number of roots were less common in females compared to males.
Oral lichen planus (OLP) is a chronic inflammatory disease with unknown etiopathogenesis. It was believed that T cells played the major role in developing the lesions. It has been recently suggested that B lymphocyte cells (B cells) and plasma cells may play a role in OLP pathogenesis.
OLP is considered as a T-cell mediated disease. It was believed that the presence of B cells and plasma cells in the sub-epithelial inflammatory infiltrate, rules out the diagnosis of OLP. This study aims to investigate the presence of B cells and plasma cells in the inflammatory infiltrate of OLP. In addition, the association between the presence of B cells and plasma cells with histopathologic features of the lesion was assessed.
To assess the presence of B cells and plasma cells, 61 cases with the diagnosis of OLP were collected. The cases with definite clinical and histopathological diagnosis of lichen planus based on WHO criteria were included. For each case, demographic information and histological characteristics were recorded.
