Background: Inter-foraminal implant placement poses a risk to the sublingual artery as it enters the mandibular\nmidline lingual foramen. Lack of consensus on the source of this artery poses a dilemma to surgeons during\nmanagement of haemorrhagic episodes. Determination of the exact source of this artery is therefore pivotal.\nMethods: This was a cross-sectional descriptive study involving 34 adult human cadavers. The facial and lingual\narteries were followed from the external carotid artery to determine whether they terminated as the sublingual\nartery. Statistical significance tests were done using the Mann-Whitney U test and Pearson product-moment\ncorrelation.\nResults: There were 30 (88.2 %) males and 4 (11.8 %) females (male/female = 15:2) aged between 25 and 40 years.\nThe origin of the sublingual artery was mainly from the lingual artery (73.5 %), the submental artery (17.6 %), or an\nanastomotic branch from the two arteries (8.9 %). The mean distance between the mandibular midline lingual foramen\n(MMLF) and the inferior border of the mandible was 15.58 mm (range 11.03ââ?¬â??19.62 mm). The mean thickness of the\nmandible at the level of the MMLF was 10.89 mm (range 8.00ââ?¬â??12.91 mm). No statistically significant difference was\nfound between the two genders with regard to the morphometric measurements.\nConclusions: The sublingual artery that enters the MMLF was found to be the sublingual artery as either a\nbranch of the lingual artery (73.5 %), the submental artery (17.6 %) or an anastomosis of the lingual and\nsubmental arteries (8.9 %)....
Objective. The aim of this study was to assess the influence of the interim plant distance on the implant primary stability (ISQ)\nby Resonance Frequency Analysis (RFA). Method. Forty-five implants were placed in the mandible of human cadavers and 108 in\nartificial bone substrates in the form of polyurethane foam blocks. Primary implant stability was successively measured first by\nRFA immediately after the placement of the first implant (A) and then after two other implants (B and C) proximal and distal to\nthe first implant. The interim plant distances were defined from 1 to 6mm and the three primary stability values measured were\ncompared. Results. On the mandibles, no correlation was observed between the interim plant distances and primary stability. On\nthe polyurethane foam block, the primary stability of implant A increased significantly (...
MTA, Bio-Oss, and dentin chips have been successfully used in endodontics. The aim of this study was to assess the adhesion and\nmigration of dental stem cells on human pulp ceiling cavities filled with these endodontic materials in an experimental model,\nwhich mimics the clinical conditions of regenerative endodontics. Cavities were formed, by a homemade mold, on untouched\nthird molars, filled with endodontic materials, and observed with electron microscopy. Cells were seeded on cavities� surface\nand their morphology and number were analysed. The phenomenon of tropism was assessed in a migration assay. All three\nmaterials demonstrated appropriate microstructures for cell attachment. Cells grew on all reagents, but they showed a differential\nmorphology.Moreover, variations were observed when comparing cells numbers on cavity�s filling versus the surrounding dentine\ndisc.The highest number of cells was recorded on dentin chips whereas the opposite was true for Bio-Oss. This was confirmed in the\nmigration assay where a statistically significant lower number of cells migrated towards Bio-Oss as compared to MTA and dentin\nchips. This study highlights that MTA and dentin chips have a greater potential compared to Bio-Oss regarding the attraction of\ndental stem cells and are good candidates for bioengineered pulp regeneration....
Background: The oral condition in children undergoing oncohematological treatment can have a negative impact\non the course of disease. Little is known about survival of tooth restorations in these patients. The aim of this study\nwas to evaluate the longevity of restorations and sealants performed by Atraumatic Restoration Treatment (ART) in\npatients undergoing oncohematological treatment.\nMethods: ART single surface restorations and sealants were performed in the experimental group (E), which\ncomprised children (2ââ?¬â??13 years old) undergoing oncohematological treatment, and in the control group (C),\nin which patients did not undergo such treatment. The same examiner evaluated the ART at 1, 3, 6 and\n12 months after preparation, using the same criteria for restorations and sealants. ART was successful if the\nsealant or restoration did not need a repair in the follow-up assessment. Descriptive, bivariate and Coxââ?¬â?¢s\nproportional hazard analyses were performed at a significance level of 5 %.\nResults: The two groups, one including 24 children (E) and the other 14 children (C), received 101 and 52\nART procedures, respectively. The success rates were 95.0 % (E) and 100 % (C) at 1 month (P = 0.233); 81.2 %\n(E) and 92.3 % (C) at 3 months (P = 0.009); 72.2 % (E) and 80.8 % (C) at 6 months (P = 0.050) and 48.5 % (E) and 73.1 %\n(C) at 12 months (P = 0.001). The final Coxââ?¬â?¢s regression model for occurrence of ART failure needing repair did not show\ndifferences between groups (E: OR = 1.6, 95 % CI 0.8ââ?¬â??2.9); primary teeth had a shorter survival than permanent teeth\n(OR = 2.1, 95 % CI 1.2ââ?¬â??3.7).\nConclusions: Oncohematological treatment did not interfere with the longevity of ART restorations and sealants,\nwhich suggests the potential use of this technique in children undergoing chemotherapy...
Context: The essential role of a general dental practitioner is recognizing the nature of the oral cavity lesions. Periapical lesions, which are\nobserved in radiographs of patients, may have odontogenic or nonodontogenic origins. This review aimed to study differential diagnosis\nof common and important periapical lesions.\nEvidence Acquisition: English-language literature were searched by manual and electronic search with the terms ââ?¬Å?periapical lesionsââ?¬Â,\nââ?¬Å?jaw neoplasmsââ?¬Â, and ââ?¬Å?non-odontogenic lesionsââ?¬Â in three data bases of MEDLINE, Google scholar, and SCOPUS among published studies\nsince 2000 to 2013. All review articles, original articles, case reports, and case series were evaluated.\nResults: In this study, it has been showed that many periapical lesions have not endodontic origin and not healing by root canal therapy.\nConclusions: The authors recommended to have paraclinical tests, especially vitality tests, in addition to clinical and radiographic\nexaminations to avoid endodontic mistreatment. In suspicious cases, biopsy of lesions, referral to pathologist, and long-term fallow-up is\nrequired....
Objective: To assess changes in voiding symptoms, serum PSA and inflammatory cytokine levels after non-surgical periodontal treatment in men with chronic periodontitis.\n\nPatients and methods: Twenty-seven men who underwent prostate biopsy because of abnormal findings on digital rectal examination or elevated PSA (â�¥4 ng/ml) participated in the study. Dental plaque (PI) and gingival(GI) indices, bleeding on probing (BOP), probing depth (PD), clinical attachment level (CAL), gingival recession(GR), PSA, IPSS, IL-1�², and C-Reactive Protein (CRP) were determined before and after periodontal treatment. The Mann-Whitney test was used to compare PSA level at baseline with prostate inflammation, prostate malignancy, and Gleason score. The Wilcoxon Rank-Sum Test was used to examine differences in baseline and post-periodontal treatment values. Change in PSA level after periodontal treatment was correlated with change in other parameters studied, using Spearman?s correlation.\n\nResults: All clinical periodontal parameters and IPSS values showed statistically significant (P<0.05) improvement after periodontal treatment. A reduction in mean PSA levels was noted 4 to 8 weeks after treatment, but did not reach statistical significance (4.53 ? 8.16 versus 4.19 ? 7.71, P=0.13). Men having >4 ng/ml PSA levels at baseline, showed significant (P<0.05) reduction in PSA after treatment (9.7 ? 11.9 versus 8.51 ? 11.6). No significant change in CRP and IL-1�²levels (p>0.05) were found. Statistically significant correlation was found between the changes in periodontal parameters and PSA levels after periodontal treatment: CAL (r=0.57, P=0.002), BOP (r=0.42, P=0.031), GI (r=0.39, P=0.04), GR (r=0.67, P=0.001). Mean PSA levels were significantly higher (P=0.02) in men with moderate/severe prostate inflammation than in those with none/mild group (6.5 ? 3.6 versus 4.3 ? 9.1 ng/ml) regardless of the presence or severity of prostate malignancy.\n\nConclusion: Periodontal treatment improved prostate symptom score and lowered PSA value in men afflicted with chronic periodontitis....
