Impacts Of A Duf2207 Family Protein On Streptococcus Mutans Stress Tolerance Responses And Biofilm Formation, Xiaochang Huang, Camile G. Laird, Paul P. Riley, Zezhang Tom Wen

School of Dentistry Faculty Publications

Locus SMU.243 in Streptococcus mutans was annotated as a member of the DUF2207 family proteins highly conserved in all bacteria but with unknown function. To investigate its role in S. mutans physiology, a SMU.243-deficient mutant was constructed using allelic exchange mutagenesis, and the impacts of SMU.243 deletion on bacterial growth, stress tolerance response, and biofilm formation were analyzed. Compared to the wild-type UA159, S. mutans lacking SMU.243 displayed a reduced growth rate and a reduced overnight culture density (p < 0.01) when grown at low pH and in the presence of methyl viologen. Relative to the parent strain, the deficient mutant also had a reduced survival rate following incubation in a buffer of pH 2.8 (p < 0.01) and in a buffer containing hydrogen peroxide at 58 mM after 60 min (p < 0.001) and had a reduced capacity in biofilm formation especially in the presence of sucrose (p < 0.01). To study any ensuing functional/phenotypical links between SMU.243 and uppP, which is located immediately downstream of SMU.243 and encodes an undecaprenyl pyrophosphate phosphatase involved in recycling of carrier lipid undecaprenyl phosphate, a uppP deficient mutant was generated using allelic exchange mutagenesis. Unlike the SMU.243 mutant, deletion of uppP affected cell envelope biogenesis and caused major increases in susceptibility to bacitracin. In addition, two variant morphological mutants, one forming rough colonies and the other forming mucoid, smooth colonies, also emerged following the deletion of uppP. The results suggest that the SMU.243-encoded protein of the DUF2207 family in S. mutans plays an important role in stress tolerance response and biofilm formation, but unlike the downstream uppP, does not seem to be involved in cell envelope biogenesis, although the exact roles in S. mutans’ physiology awaits further investigation.

Flapless Approach To Dental Implant Surgery: To Use Or Not To Use?, Rebecca Skaf Dds, Kenneth Parrera Dds, Abhiram Maddi Dds, Msc, Phd

The New York State Dental Journal

Flapless approach to implant surgery is emerging as a viable alternative to traditional implant surgery, where a full thickness flap is raised and the alveolar bone is exposed for placement of dental implants. However, there are several disadvantages of the traditional approach including patient morbidity, bleeding and post-operative complications. With the advent of digital technologies such as cone beam computed tomography (CBCT) and 3D printing of surgical guides, flapless surgery has become desirable for implant placement, especially for general dentists. This manuscript discusses the benefits and risks of the flapless approach as compared to the traditional approach for dental implant …

Use Of Dentoalveolar And Zygomatic Implants In Restoration Of Maxillary Defect Following Fibula Free-Flap Reconstruction Failure, Paul Canallatos Dds, Ms, Thom Loree Md, Amanda Colebeck Dds, Ms, Maureen Sullivan Dds

The New York State Dental Journal

Oral cancer resections cause tissue defects which result in functional complications such as masticatory dysfunction, dysphagia, articulation and phonation issues. When the defect involves the maxillary arch, obturation is needed whether it be surgical or prosthetic. In cases where surgical procedures become ineffective, prosthetic options could be challenging. This is a case of a 78-year-old male developed the diagnosis of squamous cell carcinoma of the right alveolar ridge. The patient underwent partial maxillectomy and right neck dissection with fibula free-flap reconstruction of the maxillary arch. Despite a positive doppler reading, the fibula free-flap became non-vital seven days post-operatively. At the …
