    peer reviewedBACKGROUND AND OBJECTIVE: Lactobacillus spp. and bifidobacteria are the most frequently used probiotics in oral health research. However, although probiotic effects have been suggested for other genera, such as bacilli, no trials are available to describe the effect of bacilli probiotics on gingivitis in humans. The aim of the present study was to evaluate the clinical effects of a bacilli-containing toothpaste, a mouthrinse and a toothbrush cleaner versus a placebo in patients with generalized gingivitis. MATERIAL AND METHODS: In this double-blind placebo-controlled randomized clinical trial, nonsmoking, systemically healthy patients with generalized gingivitis were included. They used a placebo or an experimental probiotic Bacillus subtilis-, Bacillus megaterium- and Bacillus pumulus-containing toothpaste, mouthrinse and toothbrush cleaner for 8 wk. Primary outcome measures of interest were plaque and gingivitis index, and the secondary outcome measures were pocket probing depth and bleeding on probing. RESULTS: Twenty male and 20 female patients were randomized over the two groups. All participants could be included in the final analysis. Although plaque and gingivitis indices were significantly reduced after 8 wk, no intergroup differences could be found at any time point. Also, for the secondary outcome measure, intragroup but no intergroup differences could be detected. No harm or unintended effects were reported by the patients after using the study products. CONCLUSIONS: This study did not show any statistically significant differences between a placebo and a bacilli-containing toothpaste, mouthrinse and toothbrush cleaner on gingivitis parameters

    Objectives Odontogenic abscesses are one of the most common dental diseases causing maxillofacial skeletal lesions. They affect the individual\u27s ability to maintain the dental structures necessary to obtain adequate nutrition for survival and reproduction. In this study, the prevalence and pattern of odontogenic abscesses in relation to age, sex, matriline, and living periods were investigated in adult rhesus macaque skeletons of the free-ranging colony on Cayo Santiago, Puerto Rico. Materials and MethodsThe skulls used for this study were from the skeletons of 752 adult rhesus macaques, aged 8–31 years, and born between 1951 and 2000. They came from 66 matrilines ranging from 1 to 88 individuals. Fistulae or skeletal lesions caused by odontogenic abscesses drainage, carious lesions, tooth fractures, tooth loss, and alveolar resorption were evaluated visually. Results Seventy-two specimens (9.57%) had odontogenic abscesses of varying severity. Males had a significantly higher prevalence than females. The prevalence of odontogenic abscesses in several matrilines was significantly higher than in the population as a whole. Animals born between 1950 and 1965 tended to have a higher prevalence of odontogenic abscesses than those born in later periods. Discussion These results suggest that oral pathologies, such as dental and periodontal abscesses in rhesus macaques are fairly common, which may indicate familial effects interwoven with ecological and social factors. The closeness of the rhesus and human genomes allows insights to understand of the epidemiology of these diseases in the human population. Further assessment of the role played by environmental and familial factors on rhesus oral health and disease are warranted

    YOU’VE GOT SOME NERVE: CASE SERIES OF OPTIC NERVE ANOMALIES

    No full text
    Introduction. Optic nerve anomalies are a group of structural malformations of the optic nerve head and surrounding tissues, which may cause congenital visual impairment and blindness. Each entity in this group of optic nerve anomalies has individually become more prevalent as our ability to differentiate between them has improved due to better characterization of cases. Case Presentation. Discussion of a case series of optic nerve anomalies with topics including optic nerve hypoplasia, optic pit, morning glory, megalopapilla, myelinated nerve fibers and disc drusen. Deviation from Expected. This case series will a) recognize the appearance and understand the description of anomalous optic nerves b) understand testing needed to further diagnose, rule out and monitor conditions. c) further understand, signs, symptoms, associations, complications and management of conditions. Discussion. When optic nerve abnormalities are detected, it is essential to differentiate between anatomical and pathological causes. This is because certain irregularities may require additional testing and or intervention. Conclusion. Optic nerve anomalies can sometimes be overlooked when the appearance is subtle. Careful evaluation, testing and monitoring is essential for proper care in order to decrease future risks of complications in those which may progress to a visually debilitating status

    The phenotypic overlap of syndromes associated with hereditary gingival fibromatosis: follow-up of a family for five years

    No full text
    PubMedID: 17395066Hereditary gingival fibromatosis (HGF) is characterized by the slowly progressive fibrous enlargement of gingival tissue. It usually develops as an isolated disorder but can also be one feature of various syndromes. The currently preferred terminology of these syndromes mainly describes the clinical features of the disorder without identifying the cause. In this report, we present the 5-year follow up of a family with HGF and features of 3 previously described syndromes: Jones syndrome, Zimmerman-Laband syndrome, and HGF-hypertrichosis syndrome. The 45-year-old father had HGF, hypertrichosis, hearing loss, and short stubby fingers and toes with hypoplasia of the terminal phalanges and hypoplasia of the nails on the thumbs. The features of 13-year-old son were almost identical to those of his father except for hypertrichosis, but in addition he was mentally retarded. Although the 10-day-old son had HGF and defective fingers, the mother and 7-year-old daughter were unaffected. Owing to the overlap of these syndromes, we argue that the identification of the genetic pathways and mechanisms will be the most important factor in classifying these disorders, with the phenotype playing a minor role. © 2007 Mosby, Inc.

    Oral challenge test for the diagnosis of gingival hypersensitivity to apple: A case report

    No full text
    PubMedID: 16504864Food intolerance is the term used to describe a hypersensitivity reaction to a food component. These reactions refer to the drug-like side effects caused by a range of chemicals that may be present in food as natural or added components. The range of symptoms which can be induced by food intolerance are very similar to those caused by food allergy, oral allergy syndrome, acute infectious diseases and vesiculobullous disorders; so that on initial presentation, it can be difficult to differentiate between these conditions. A 48-year-old woman with complaints of allergic symptoms was examined with skin prick test (SPT), specific IgE analysis, and oral challenge test for definitive allergen determination. The patient was negative in both specific IgE detection and SPT with commercial extracts of apple, whereas the oral challenge test revealed positive objective symptoms with blister and ulcer formation. Apple has been reported to be the cause of food allergy. To our knowledge, there is no report of apple intolerance in which the lesions are only confined to gingival tissues. © 2006 Elsevier Inc.

    The most important problems of modern dentistry cover not only the early diagnosis but also prevention of dental caries, including the one based on the use of various hygienic products and therapeutic agents. Normally, the processes of re- and demineralization in the oral cavity are in a state of dynamic. However, in the presence of cariogenic factors, the balance is shifted towards demineralization. In the event of initial caries, enamel remineralization is possible only to a certain extent, and specifically, for a reversible degree of carious lesion. There was an idea about structural changes in polymer-based consumable dental materials including toothpastes. The purpose of the study is to increase the efficiency of dental caries prevention based on the activation of metabolic processes in dental hard tissues with the use of R.O.C.S. Active Calcium toothpastes (Russian-Swiss “DRC-Group” company) modified by an electromagnetic field. As a result of the experimental part of the study, certain changes in the properties of the R.O.C.S. Active Calcium toothpastes under the electromagnetic field influence including microstructural transformation of the toothpaste (an increase in the size of the polymer matrix particles and a decrease in the distance between them confirmed by the electron microscopy findings), confirmed by the transmission electron microscopy results. The investigations with the help of X-ray microanalysis made it possible to clarify the chemical composition of the surface layer of the tooth enamel, for the first time to reveal in detail the concentration of micro- and macroelements of organic and inorganic nature, to trace the changes occurring under controlled tooth cleaning with the R.O.C.S. Active Calcium toothpaste treated with an electromagnetic field. The obtained results promote the further studies of laws in change of physical and mechanical properties of treatment-and-prophylactic means under the electromagnetic field influence in respect of dental caries preventive maintenance efficiency increase. © 2018, European Association for Predictive, Preventive and Personalised Medicine (EPMA).Ministry of Education and Science of the Russian Federation: 1, 1, 1, 1 Ministry of Education and Science of the Russian Federation: 1, 1, 1, 1The study was approved by the local committee for ethics in research of State Funded Educational Institution of Higher Education BVoronezh N.N.

    Diode laser for harvesting de-epithelialized palatal graft in the treatment of gingival recession defects: A randomized clinical trial

    No full text
    PubMedID: 26660000Aims The aim of present randomized controlled clinical study was to evaluate the effects of the use of diode laser for graft harvesting and palatal wound irradiation on post-operative morbidity and root coverage outcomes after a coronally advanced flap (CAF) with de-epithelialized gingival grafts (DGG). Methods Fifty-two patients with isolated recessions were treated. The CTG resulted from the de-epithelialization of a free gingival graft (FGG) with blade (control group:DGG-B) or diode laser (DL) (test group:DGG-L). The DL was used to de-epithelialize the outer part of the FGG and photo-biostimulate the palatal wound area. Post-operative morbidity was evaluated by using Oral Health-related Quality of Life (OHQoL) and Visual Analogue Scale-discomfort (VAS). Root coverage outcomes were also evaluated 6 months after operation. Results Statistically significant differences were found for OHQoL (p = 0.0001) and VAS (p = 0.0001) at the 7th day post-operatively favouring test sites. Root coverage results did not show a statistically significant difference. Conclusions While both techniques were effective with regard to root coverage at 6 months, the DGG-L technique decreased post-operative morbidity associated with palatal donor-site surgery. © 2015 John Wiley & Sons A/S.
