Is anterior guidance a key factor on planning implant treatment for free-end missing in the posterior mandible?

J Oral Implantol 2018 Dec 12. Epub 2018 Dec 12.

1 Kyushu Dental University Department of Oral Reconstruction and Rehabilitation Kyushu Dental University.

To perform safe implant treatment, the anatomical structure and bone quality at implant placement sites are evaluated based on a patient's CT data, but there is no definite method to determine placement sites and the appropriate number of implants. The objective of this study was to investigate the influence of the number and arrangement of implants on the stress distribution in 3-unit posterior fixed partial dentures for the posterior mandible by mechanical analysis using the finite element method. Three-dimensional finite element analysis models were constructed from the CT data of a patient with missing mandibular teeth (Nos. Read More

Procurement, Transportation, and Storage of Saliva, Buccal Swab, and Oral Wash Specimens.

Methods Mol Biol 2019 ;1897:99-105

Department of Pathology and Laboratory Medicine, David Geffen School of Medicine at UCLA, Los Angeles, CA, USA.

Saliva and oral/buccal samples have become increasingly valuable sources of genetic material for clinical applications. The DNA obtained by these samples is of comparable quality to that from blood samples. This, coupled with the ease of collecting saliva and oral/buccal samples, has led to increased numbers of such samples being incorporated into biobanks. Read More

Olfactory ensheathing cells promote nerve regeneration and functional recovery after facial nerve defects.

Neural Regen Res 2019 Jan;14(1):124-131

Department of Otolaryngology Head and Neck Surgery, Changzheng Hospital, Second Military Medical University, Shanghai, China.

Olfactory ensheathing cells from the olfactory bulb and olfactory mucosa have been found to increase axonal sprouting and pathfinding and promote the recovery of vibrissae motor performance in facial nerve transection injured rats. However, it is not yet clear whether olfactory ensheathing cells promote the reparation of facial nerve defects in rats. In this study, a collagen sponge and silicone tube neural conduit was implanted into the 6-mm defect of the buccal branch of the facial nerve in adult rats. Read More

Oromucosal drug delivery: Trends in in-vitro biopharmaceutical assessment of new chemical entities and formulations.

Eur J Pharm Sci 2018 Nov 28;128:112-117. Epub 2018 Nov 28.

Drug Transport & Delivery Group, Department of Physics, Chemistry & Pharmacy, University of Southern Denmark, Odense, Denmark. Electronic address:

Development of buccal application forms is gaining increasing interest in recent years, mostly driven by the insight that enabling formulations may help to overcome limitations as well as the need for patient-oriented medicines. A key characteristic of dosage forms is whether they can grant absorption of therapeutically relevant doses across the limited absorption area in the mouth and realistic time window. Despite the generally accepted paradigm to replace or at least reduce animal experiments, current transport studies towards oromucosal drug delivery still are dominated by in vivo or ex vivo animal studies.

Methods: In 13 patients the maxilla was augmented with calvarial bone followed by simultaneous dental implant placement (total: 68 implants). In the frontal "knife edge" region, implants were inserted in the buccal plated area. Read More

Buccal Bullfrog ( Shaw) Oil Emulsion: A Mucoadhesive System Intended for Treatment of Oral Candidiasis.

Pharmaceutics 2018 Dec 3;10(4). Epub 2018 Dec 3.

Graduate Program in Health Sciences, Federal University of Rio Grande do Norte (UFRN), Av. General Gustavo Cordeiro de Faria-SN-Petrópolis, Natal 59012-570, Brazil.

Oral candidiasis (OC) is an infectious disease caused by microorganisms of the genus , leading to lesions in the buccal cavity. Its treatment consists of the administration of topical or systemic antifungal agents, which may compromise the patient compliance due to its side effects, highlighting the need for alternative treatments. In this scenario, bullfrog oil, an animal oil composed of a pool of saturated and unsaturated fatty acids, is introduced as a potential antifungal raw material. Read More

The longevity of an immediate implant placement in a molar area with the flapless extraction technique has not yet been deeply investigated, and only a few studies have previously been published. This article describes a successful case of immediate implant placement with a follow-up evaluation after more than five years. An immediate implant was placed in a fresh socket after an atraumatic extraction with no flap elevation. Read More

One-stage reconstruction by dual-innervated double muscle flap transplantation with the neural interconnection between the ipsilateral masseter and contralateral facial nerve for reanimating established facial paralysis: A report of 2 cases.

Microsurgery 2018 Dec 4. Epub 2018 Dec 4.

Department of Plastic and Reconstructive Surgery, School of Medicine, Tokyo Women's Medical University, Tokyo, Japan.

The authors developed a one-stage double-muscle reconstruction technique for facial paralysis using a latissimus dorsi (LD) flap and a serratus anterior (SA) flap, which were dually reinnervated by the contralateral facial nerve (FN) and ipsilateral masseter nerve (MN). The procedure was performed for 61-year-old man 3-years after resection of a malignant tumor and a 24-year-old woman 10-years after temporal fracture with facial paralysis. A double-muscle flap comprising left LD and SA flaps was harvested, a 15-cm thoracodorsal nerve (TN) section was attached to the LD flap, and 5-cm and 1-cm sections of the long thoracic nerve (LTN) were attached to the proximal and distal sides of SA flap.

Childhood adversity and DNA methylation in two population-based cohorts.

Transl Psychiatry 2018 Dec 3;8(1):266. Epub 2018 Dec 3.

MRC Integrative Epidemiology Unit at the University of Bristol, Population Health Sciences, Bristol Medical School, University of Bristol, Bristol, UK.

Childhood adversity affects later health, but the underlying molecular mechanisms are unclear. Although there is some evidence from animal models and case-control studies of a role for DNA methylation, evidence from human population-based studies is limited. In two cohorts (mothers from the Avon Longitudinal Study of Parents and Children, ALSPAC, n = 780 and women from the MRC National Survey of Health and Development, NSHD, n = 552), we assessed the association of seven adverse childhood experiences (ACEs: parental physical illness, parental mental illness, parental death, parental separation, suboptimal maternal bonding, childhood illness and child maltreatment) as well as their combination (ACE score) with genome-wide DNA methylation levels measured using the Illumina Infinium HumanMethylation450 BeadChip in peripheral blood at mean age 47 years (ALSPAC) and in buccal cells at age 53 years (NSHD).
