Peripheral giant cell granuloma (PGCG) is a relatively common benign reactive lesion of the oral cavity which can occur at any age.\nCTCFL/BORIS (CTCF like/Brother of the Regulator of Imprinted Sites) and CTCF (CCCTC-binding factor) are paralogous genes\nwith an important role in the regulation of gene expression, genomic imprinting, and nuclear chromatin insulators regulation.\nBORIS expression promotes cell immortalization and growth while CTCF has tumor suppressor activity; the expression pattern\nmay reflect the reverse transcription silencing of BORIS.The aim of this work was to describe a histopathological and molecular\napproach of an 8-year-old pediatric male patientwith PGCGdiagnosis. It was observed that the PGCGunder study expressed CTCF\nas well as BORIS mRNAs alongside with the housekeeping gene GAPDH, which may be related to possible genetic and epigenetic\nchanges in normal cells of oral cavity....
Background. A number of surgical techniques for implant site preparation have been advocated to enhance the implant of\nprimary and secondary stability. However, there is insufficient scientific evidence to support the association between the surgical\ntechnique and implant stability. Purpose. This review aimed to investigate the influence of different surgical techniques including\nthe undersized drilling, the osteotome, the piezosurgery, the flapless procedure, and the bone stimulation by low-level laser therapy\non the primary and/or secondary stability of dental implants. Materials and methods. A search of PubMed, Cochrane Library, and\ngrey literature was performed. The inclusion criteria comprised observational clinical studies and randomized controlled trials\n(RCTs) conducted in patients who received dental implants for rehabilitation, studies that evaluated the association between the\nsurgical technique and the implant primary and/or secondary stability. The articles selected were carefully read and classified as\nlow, moderate, and high methodological quality and data of interest were tabulated. Results. Eight clinical studies were included\nthen they were classified as moderate or high methodological quality and control of bias. Conclusions. There is a weak evidence\nsuggesting that any of previously mentioned surgical techniques could influence the primary and/or secondary implant stability....
Purpose. To evaluate the impact of an educational workshop on parental knowledge, attitude, and perceived behavioral control\nregarding their childâ��s oral health. Materials and Methods. A one-time oral health education workshop including audio/visual and\nhands-on components was conducted by a trained dentist and bilingual community workers in community locations. Participants\nwere African parents of children who had lived in Canada for less than ten years. The impact of the workshop was evaluated\nby a questionnaire developed based on the theory of planned behavior. Results. A total of 105 parents participated in this study.\nParticipants were mainly mothers (mean age 35.03 �± 5.4 years) who came to Canada as refugee (77.1%) and had below high school\neducation (70%). Paired t-test showed a significant difference in participantsâ�� knowledge of caries, preventive measures, and benefits\nof regular dental visits after the work shop (P value < 0.05). A significant improvement was also found in parental attitudes toward\npreventive measures and their perceived behavioral control (P < 0.05). Parentsâ�� intention to take their child to a dentist within\nsix months significantly altered after the workshop (P value < 0.05). Conclusions. A one-time hands-on training was effective in\nimproving parental knowledge, attitude, perceived behavioral control, and intention with respect to their childâ��s oral health and\npreventive dental visits in African immigrants...
Objective. The aim of this paper is to present an uncommon clinical and radiographic aspect of odontogenic keratocyst (OKC)\nmimicking paradental cyst. Methods. A 32-year-old female patient showed a well-delimited radiolucent lesion connected with the\nroot of the left thirdmolar with close anatomical relationship with the mandibular canal.The clinical, radiographic, and anamnestic\nfeatures lead us to diagnose a paradental cyst that was treated by enucleation after extraction of the partially impacted tooth. Results.\nHistological analysis showed typical histological features of PKC such as the presence of a lining of stratified squamous epithelium\nwith a well-defined basal layer of palisading columnar of cuboidal cells. Conclusion. Initial X-ray analysis and the position of the\nlesion related to the third mandibular tooth caused us to mistakenly diagnose a paradental cyst.We were only able to identify the\ncyst as an PKC rather than a paradental cyst after histological analysis....
The aim of this study was to evaluate the clinical reliability of the Pederson index in preoperative assessment of the difficulty of\nsurgical removal of impacted mandibular third molars. Pederson index was found to be unreliable predictor of true difficulty with\nlow sensitivity and specificity. A new index (Kharma scale), which takes into consideration the anatomical form of tooth roots, is\nproposed and evaluated both pre- and postoperatively.The results of the evaluation indicate that the new estimating index is more\nreliable and accurate measure than Pederson scale....
