Over the last 29 years, I have witnessed many technological advances in dentistry. Some of these advances have included computers throughout the office, digital X-rays, digital intra-oral photography, loupe and microscope magnification, and CAD/CAM technology, just to name a few. One of the most significant technological advances has been the evolution of the dental laser, and it’s this technology that’s really firing my passion for dentistry.
Lasers have been used in dentistry for several decades, but during the last five years they have become widely accepted and now tens of thousands of dentists in the U.S. and around the world have implemented lasers. Market acceptance of dental lasers is rapidly growing at a level where digital imaging was five to seven years ago.
In my practice we have several lasers for both hard- and soft-tissue applications, which are used for a wide range of procedures. It’s well-established that different procedures require different laser wavelengths. Wavelength is important because specific body tissues (chromophores) interact in different ways depending on the laser source. Therefore, it’s important to use the proper wavelength that is tissue-specific for the procedure.
The following are a few of the laser procedures performed in our office every day and the clinical advantages they offer our practice and, most importantly, our patients.
The near infrared diode laser has become my laser of choice for hygiene and soft tissue. It’s extremely effective for hygiene procedures such as laser bacterial reduction (LBR) and laser de-epitheliazation during scaling and root planing. Additionally, it’s excellent for soft-tissue surgical procedures such as frenectomy, gingivectomy, fibroma removal, and gingival retraction for crown and bridge impressions.
The most versatile laser I have is the erbium mid-infrared wavelength hard/soft-tissue laser. I use this laser several times a day for no-shot, no-drill cavity preps. My patients love being able to avoid having shots and post-op numbness. This laser gives me the ability to quickly and effectively remove decay, and often these restorations weren’t scheduled, but discovered during hygiene examinations. We can complete these procedures in one appointment and avoid the inconvenience of rescheduling the patient. With my erbium laser I can perform these procedures fast and often without anesthesia.
In addition, by lengthening the pulse duration, I also can perform many soft-tissue and bone procedures. Procedures like apicoectomy, gingivectomy, osseous recontouring and laser periodontal surgery are examples of treatments performed with the erbium laser.
Finally, lasers are now being used during endodontic treatment in the form of laser activated irrigation to greatly reduce bacteria and debris found in the canals without a net thermal elevation within the canal. Lasers also are now being used for snore reduction. The role of lasers in dentistry is continuing to increase as we see ongoing research in both lasers and their use in various applications in dentistry. The decision is no longer whether to add a laser to your practice, it’s just a matter of which laser will best fulfill your needs.

Mandibular Osteomyelitis Associated to Candida Albicans in Marijuana and Heroin Abusers: Literature Review and Case Series
By Mikhail Daya, DMD*; Isabella Anderson, BS+; and, Jason Portnof, DMD, MD, FACS, FIDC**
Background: Osteomyelitis of the mandible is most commonly caused by bacterial infections and is rarely linked to fungal infections. Friedman et al. studied the relationship of multiple drugs, including marijuana, opioids, nicotine and alcohol, and its effect on the immune system. It’s important to consider potential risks and complications of patients who are immunocompromised and present a history of substance abuse. These complications include infections and osteomyelitis, which can be associated with multiple microorganisms, such as fungus. Candida albicans is commonly found in skin and mucosa of healthy individuals; however, it has been proven to cause disease in individuals who are immunocompromised.
Case Presentation: Two cases of mandibular osteomyelitis after routine dental extractions and a history of drug abuse, including heroin and marijuana, are presented in this case series. The patients were both male, ages included a 40-year-old (Patient A) and a 45-year-old (Patient B). Both patients underwent routine dental extractions performed by two different oral surgeons. Patient A underwent routine extraction of tooth No. 19 and Patient B had an extraction of erupted tooth No. 32. Due to recurrent infections and non-healing extraction sites, both patients were referred to the Department of Oral and Maxillofacial Surgery at Nova Southeastern University. Patients A and B underwent multiple courses of antibiotics as well as incision and drainage without resolution. Cultures of the infected sites were collected and analyzed for aerobes, anaerobes and fungus. In the final microbiology, both cases yielded positive results for Candida albicans.
Once the final microbiology yielded positive results for Candida albicans, Patient A was treated with irrigation and debridement, and Patient B underwent a right mandibular resection. Both patients also were treated in combination with antimicrobial therapy and fluconazole leading to complete resolution.
Discussion: Osteomyelitis is defined as a progressive inflammatory condition of the bone and bone marrow.1,2 This rare condition can affect any bone, but is commonly seen in teeth bearing bones of the facial skeleton, due to direct access of microorganisms through infected teeth.5 In 2012, Slenker et al. studied 212 cases of Candida osteomyelitis. In this study, the most commonly affected sites were vertebrae and sternum. Interestingly, only six of them affected the facial skeleton.4
Infections of dental origin have been historically associated to bacterial microorganisms; however, in recent years there has been a trend in increasing infections associated to fungal pathogens.6 This increase in prevalence of Candida infections have been associated to contributing factors such as growth in population of immunosuppressed patients, invasive surgeries and overuse of broad-spectrum antibiotics.7
We show two cases of mandibular osteomyelitis after routine dental extraction in patients with a history of marijuana and heroin abuse as their only significant comorbidity. Friedman et al. demonstrated a correlation between marijuana and heroin abuse and a susceptibility to infections; this is due to the direct effect of these drugs over the immune response against pathogens.3 Marijuana is the common name given to Cannabis sativa; this plant has been widely used for recreational and medicinal purposes.3 Marijuana has been directly associated to increased susceptibility to infections because of its effect on immune cells, macrophages, lymphocytes and cytokines.9,10,11 On the other hand, heroin and other opioids have been linked to increase susceptibility to infection by direct exposure of pathogens through injections as well as their direct action in immune cells.12,13
Both cases presented here were treated with a combination of surgical debridement and fluconazole. The management of Candida osteomyelitis has not been well established due to the uncommon nature of this condition. Treatment recommendations for Candida osteomyelitis are based on case reports and case series. Amphotericin B (AmB) has been used widely in the past;14 however, more recent literature supports the use of fluconazole or echinocandin over AmB due to high toxicity rate.4,15,16 Recommendations of the Infectious Diseases Society of America include the use of different antifungal combinations and surgical debridement in selected cases.
Conclusion: Although mandibular osteomyelitis is most commonly caused by bacterial microorganisms, special attention must be given to patients with medical histories of immunosuppression and illicit drug use of cannabis and opiates. Patients who do not respond to broad-spectrum antibiotics might benefit from bacterial cultures, fungal cultures and sensitivity. In cases of positive fungal microorganisms, anti-fungal treatment with an antifungal agent such as oral fluconazole is indicated if fungal organisms are yielded in the culture.
