Antimicrobial Effect of a Single Dose of Amoxicillin on the Oral Microbiota

Antimicrobial Effect of a Single Dose of Amoxicillin on the Oral Microbiota
Amoxicillin is commonly used in oral surgery for antimicrobial prophylaxis against surgical-site infection and bacteremia because of its effect on oral streptococci. The aim of this study was to determine whether amoxicillin reaches the break-point concentrations in saliva and has any effect on the salivary microbiota, colonizing bacteria on mucosal membranes and on the gingival crevice after a single dose of amoxicillin. A single dose given as prophylaxis to prevent a surgical-site infection results in a significant reducing effect on the oral streptococcal microflora in the gingival crevice and may have an impact on bacteria spreading into tissues and the bacteria of streptococci.

Effectiveness of a Super-Pulsed CO2 Laser For Removal of Biofilm From Three Different Types of Implant Surfaces: An In Vitro Study

Effectiveness of a Super-Pulsed CO2 Laser For Removal of Biofilm From Three Different Types of Implant Surfaces: An In Vitro Study
As dental implants become a routine part of dental practice, so too will the prevalence of peri-implant diseases. Inherent to the treatment of peri-implant disease is the removal of microbial biofilms from the implant surface. Currently, there is no standardized protocol for application of any treatment modality directed at implant surface decontamination. In this in vitro study, we report on the effectiveness of a super-pulsed CO2 laser, delivering an average fluence of 6.3 to 113 J/cm2, to remove biofilm from three different types of implant surface topographies. Biofilms ranged in thickness from 5 to 15 μm. An average fluence of 19 J/cm2 was sufficient to achieve 100% ablation of the biofilm on hydrophilic sandblasted and acidetched surface specimens (SA). However, to achieve 100% ablation of biofilm on HA and highly crystalline, phosphate enriched titanium oxide (PTO) surfaced implants required an average fluence of 38 J/cm2.

Oral Soft Tissue Laser Ablative and Coagulative Efficiencies Spectra

Oral Soft Tissue Laser Ablative and Coagulative Efficiencies Spectra
The key to the success of soft tissue lasers is their ability to cut and coagulate the soft tissue at the same time. Present work is aimed to derive the wavelength-dependent differences in photo-thermal ablation and coagulation efficiencies for oral soft tissue pulsed dental Near-IR Diode, Mid-IR Erbium and IR CO2 lasers. Even though the soft tissue photothermal ablation has been extensively studied, there remains a discrepancy between (a) the widely proliferated notion about efficient Near-IR 800-1,100 nm laser ablation of the oral soft tissue, and (b) studies reporting the inefficient soft tissue Near-IR absorption/ablation. Indeed, the notions about “the key to the usefulness of the Nd:YAG is that this wavelength is highly absorbed in oral soft tissue”, and “all currently available dental laser instruments and their emission wavelengths have indications for use for incising, excising... oral soft tissue surgery”, contradict an observation illustrated here...

Bisphosphonates and Their Impact on Patient Treatment

Bisphosphonates and Their Impact on Patient Treatment
There has been increasing discussion concerning a variety of implications for patients who have been administered bisphosphonates, which are FDA-approved chemical agents used in the treatment of osteoporosis, metastatic cancer involving the bone, and Paget's disease. I The first report of the biological characteristics of bisphosphonates was published in 1968, when scientists discovered that bisphosphonates have a marked ability to inhibit bone resorption. Bisphosphonates suppress or reduce bone…

Prosthetic Considerations with Periodontal Root Resective Therapy Part 2

Prosthetic Considerations with Periodontal Root Resective Therapy Part 2
The treatment of advanced furcation lesions may require the removal of a portion of the crown and its associated root, or resection of only one root from a multi rooted tooth. This resective-type of therapy is a definitive treatment because it predictably enables clinicians to better access the remaining tooth structure for periodontal and subsequent prosthetic therapy. The morphology of tooth preparation for hemisective periodontal therapy is critical to facilitate the patient's ability to perform…

Guide to Diagnosing & Treating Endodontic & Periodontal Lesions
The gathering of diagnostic information using radiographs and conventional pulp vitality testing serves as the current foundation for milking uncomplicated endodontic diagnoses. Acquiring and investigating diagnostic information can be analogous to piecing together a puzzle. As each piece fits, a picture begins to emerge. but if the puzzle contains too many pieces and inherently becomes more complex, frustration mounts and elucidating the pIcture becomes more difficult. Therefore, the practitioner must…

Oral Pyogenic Granuloma in Pregnancy

Oral Pyogenic Granuloma in Pregnancy
An oral pyogenic granuloma can develop immediately following the first trimester of pregnancy. Usually an oral pyogenic granuloma is a slow-growing mass that does not, upon excision, leave a large defect in the periodontium requiring surgical repair. However an oral pyogenic granuloma often grows into a large mass in the gravid female, which generally emanates from a stalk, originating at an interdental gingival papilla. Although such lesions are commonly known as 'pregnancy tumors' or 'pregnancy epulides',…
