Lingual mucosal graft urethroplasty for anterior urethral reconstruction.
2008
Objective: Evaluate the use of lingual mucosal graft (LMG) in anterior urethral strictures.Methods: From January 2001 to December 2006, 29 men (mean age, 48.5 yr) with anterior urethral strictures underwent graft urethroplasty with LMG. The mean length of stricture was 3.6 cm. Patients with bulbar, penile, or bulbopenile strictures received one-stage dorsal free graft urethroplasties. In patients with failed hypospadias repair we performed a two-stage urethroplasty. Criteria for successful reconstruction were spontaneous voiding with no postvoid residual urine and no postoperative instrumentation of any kind. Clinical assessment included the donor site morbidity.Results: Mean follow-up was …
Soft and hard tissue alterations around implants placed in an alveolar ridge with a sloped configuration.
2012
Aim: The aim of this study was to evaluate soft and hard tissue alterations around implants placed in healed, sloped ridge sites. Materials and methods: In this prospective multi-center study, 65 patients between 20 and 74 years of age and with a need for a single tooth replacement were included. All patients presented with a recipient implant site demonstrating a lingual‐buccal bone height discrepancy of 2.0‐5.0 mm and with a neighboring tooth on its mesial aspect. Implant placement (OsseoSpeed Profile implants; Astra Tech AB, M! olndal, Sweden) was performed using a non-submerged installation procedure. The implants were placed in such a way that the sloped part of the device was located …
Enhanced In Situ Availability of Aphanizomenon Flos-Aquae Constituents Entrapped in Buccal Films for the Treatment of Oxidative Stress-Related Oral D…
2019
In recent years, the key role of oxidative stress in pathogenesis of oral diseases has been emphasized and the use of antioxidant agents has been encouraged. Aphanizomenon flos-aquae (AFA) is a unicellular blue-green alga with antioxidant and anti-inflammatory properties. The aim of this study was the formulation and characterization of mucoadhesive thin layer films loaded with AFA, finalized to the treatment of oxidative stress (OS)-related oral diseases. First, to enhance the bioavailability of AFA constituents, the raw food grade material was appropriately treated by a high frequency homogenization able to disrupt cell walls. Thus, Eudragit®
Stimulated and unstimulated saliva samples have significantly different bacterial profiles
2018
Epidemiological studies use saliva on a regular basis as a non-invasive and easy-to-take sample, which is assumed to be a microbial representative of the oral cavity ecosystem. However, comparative studies between different kinds of saliva samples normally used in microbial studies are scarce. The aim of the current study was to compare oral microbiota composition between two different saliva samples collected simultaneously: non-stimulated saliva with paper points and stimulated saliva collected after chewing paraffin gum. DNA was extracted from saliva samples of ten individuals, then analyzed by 16S rRNA pyrosequencing to describe bacterial diversity. The results demonstrate significant d…
Mucoadhesive Polymeric Films to Enhance Barbaloin Penetration Into Buccal Mucosa: a Novel Approach to Chemoprevention.
2018
Nowadays, chemoprevention by administering natural supplements is considered an attractive strategy to reverse, suppress, or prevent the evolution of premalignant oral lesions. In particular, Barbaloin exhibits anti-proliferative, anti-inflammatory, and anti-cancer properties, and it results useful in multi-therapy with classic chemotherapeutics. Therefore, in this work, mucoadhesive buccal films, as locoregional drug delivery system able to provide a targeted and efficient therapeutic delivery of Barbaloin, are proposed. Thus, Aloin extract-loaded Eudragit (R) RL100 or Eudragit (R) RS100-based buccal films were designed in order to obtain an easily self-administrable formulation capable of…
Closure of oroantral communication with buccal fat pad after removing bilateral failed zygomatic implants: a case report and 6-month follow-up
2015
The aim of this study was to assess the use of buccal fat pad (BFP) technique as an option to close oroantral communications (OAC) after removing failed zygomatic implants in a patient with a severely resorbed maxilla, and to determine the degree of patient satisfaction. A 64-year-old woman presented recurrent sinusitis and permanent oroantral communication caused by bilateral failed zygomatic implants, 3 years after prosthetic loading. Zygomatic implants were removed previous antibiotic treatment and the BFP flap technique was used to treat the OAC and maxillary defect. The degree of patient satisfaction after treatment was assessed through a visual analogue scale (VAS). At 6-months follow…
Closure of oroantral communications with Bichat´s buccal fat pad. Level of patient satisfaction
2015
Purpose: To report the closure of oroantral communications with the pedicled buccal fat pad in a series of patients, and to determine the level of patient satisfaction after the surgery. Study Design: A prospective study of patients diagnosed of unilateral or bilateral oroantral communication (OAC) closed using the buccal fat pad between May 2012 and January 2013 was performed. Data analysis extended to: age, sex, and cause, location and size of oroantral communication. Complications and success related to buccal fat pad surgery were evaluated. Also, patient satisfaction was assessed after six months of surgery. Results: Nine patients (3 men and 6 women) with a mean age of 50.5 years and 11…
Utilization of pedicled buccal fat pads for coverage of the lateral relaxing wound: A review of literature and a case series of 15 patients
2018
Background The buccal fat pad (BFP) is an encapsulated mass originated from a specific fat tissue in various volume throughout the life of each person and BFP has been used in various surgeries as a source of useful graft material due to its easy accessibility and rich vascularization. Case Report This report describes fifteen patients who were treated with buccal fat pads (BFP) as a pedicled graft for lateral relaxing wound closure in primary cleft palate surgery. A review of relevant literature is also presented. Results All patients had a mean follow-up of 3.7 weeks with a minimum follow-up time of three weeks and a maximum follow-up of four weeks. All patients who had an uneventful imme…

Shaping ability of Mtwo and Twisted File rotary systems in curved root canals
2012
Objective: To compare the straightening of root canal curvature, the apical transportation, the loss of working length and the working time using two rotary systems. Study design: Sixty buccal root canals with angles of curvature between 30 to 99º were instrumented with Mtwo and Twisted File rotary instruments. A series of pre- and post-operative radiographs were superimposed to determine the straightening of root canal curvature and apical transportation. The loss of working length and working time were also calculated. Results: All data were analyzed by means of the Student´s t-test and Mann-Whitney U-test. No statistically significant differences in the straightening of root canal curvat…
