BACKGROUND: Chronic prostatitis (CP) and benign prostatic hyperplasia (BPH) are complex inflammatory conditions for which the etiological determinants are still poorly defined. Periodontitis is caused by subgingival colonizing bacteria in the oral cavity. The causal effect of periodontal disease on prostatic inflammation has not been established. The purpose of this study is to isolate oral pathogens from expressed prostatic secretions of patients with periodontal disease and chronic prostatitis or benign prostatic hyperplasia...

Small cell lung carcinoma (SCLC) is an uncommon tumor characterized by an aggressive behavior with early metastasis, usually to the contralateral lung, liver, brain, and bones. There are only five cases of this particular tumor metastasizing to the oral cavity described in the English literature. We present the case of metastatic SCLC in the mandible with radiographic findings resembling a residual cyst. A 66-year-old man with previous diagnosis and treatment for a SCLC was referred to the Stomatology Department with a history of persistent pain in the mandible 1 year after the inferior right pre-molar tooth extraction...

Herzl Chai, Brian R Lawn
OBJECTIVE: Filled MOD restorations show near-complete recovery of tooth strength relative to the newly prepared, unfilled state. The present study examines the underlying mechanics of this recovery by more closely quantifying the mode of splitting fracture from the cavity base. By understanding the role of specific cavity dimensions on fracture resistance, useful clinical guidelines concerning MOD morphologies are formulated. METHODS: A systematic in vitro study is made of the load-bearing capacity of filled and unfilled MOD cavities by axially loading extracted molar teeth with a hard metal ball...

Background: Periodontitis is a destructive inflammatory disorder of the periodontium caused by the destruction of periodontal tissues namely the PDL, cementum, alveolar bone, and gingiva. Once these tissues are lost, the foremost goal of periodontal therapy is to regenerate the diseased tissues if possible to their original form, architecture, and function. Various regenerative procedures were employed and still a gap was found in achieving the goal. As stem cells are characterized by their ability to self-renew and differentiate to produce specialized cells, there could be a possibility of using them for regenerative therapy...

This case report discusses the successful endodontic treatment of an open apex maxillary right permanent central incisor that had been avulsed and incorrectly replanted in a 7-year-old patient. The tooth was carefully re-extracted followed by cleaning of the alveolar socket and immediate replantation. However, pulp necrosis was diagnosed, and regenerative endodontic treatment was performed. The root canal system was disinfected by passive ultrasonic irrigation with 2.5% sodium hypochlorite. At the first visit, the tooth was repositioned and immobilized with an appropriate semirigid splint...

BACKGROUND: The CBCT imaging technique exhibits proper accuracy to determine the internal anatomy of teeth. Therefore, this technique can use to estimate age by measuring the amount of decrease in the volume of the pulpal cavity of teeth. The aim of the present study was to evaluate the correlation between chronological age and pulp-to-tooth volume ratios in anterior teeth with the use of the CBCT technique and to determine a regression model to estimate human age. MATERIAL AND METHODS: In this present descriptive-analytical study, 122 subjects (46 males and 76 females), with an age range of 13-70 years, were evaluated...

The purpose of this report is to introduce Cu-sil like denture as a functional space maintainer. Here, we report two paediatric cases treated with Cu-sil like denture with multiple edentulous spaces and partially erupted/compromised permanent teeth. Cu-sil like denture not only serves as removable partial functional space maintainer, but also restores the vertical dimension of occlusion, mastication and aesthetics in children. Cu-sil like denture is used in elderly patients who are not willing for extraction of remaining few healthy teeth in the oral cavity...

Oral health status must be considered in the care of children with obesity (OB) and diabetes mellitus (DM). The health of these patients' mouths may have significant effects on their overall health and evolution of their disease. Here we address periodontal disease (PD) and dental caries (DC), since these are two of the most common chronic diseases affecting OB and DM patients. OB plays a plausible role in the development of PD. Both overall OB and central adiposity are associated with increased hazards of gingivitis and its progression to PD...

Vertebrate dentitions are extraordinarily diverse in both morphology and regenerative capacity. The teleost order Tetraodontiformes exhibits an exceptional array of novel dental morphologies, epitomized by constrained beak-like dentitions in several families, i.e., porcupinefishes, three-toothed pufferfishes, ocean sunfishes, and pufferfishes. Modification of tooth replacement within these groups leads to the progressive accumulation of tooth generations, underlying the structure of their beaks. We focus on the dentition of the pufferfish (Tetraodontidae) because of its distinct dental morphology...

Streptococcus mutans is recognized as one of the key contributors to the dysbiotic state that results in dental caries. While existing treatment strategies reduce the incidence of tooth decay, they also eliminate both the cariogenic and beneficial microbes. Here we introduce a novel treatment alternative using Sephadex, cross-linked dextranomer microspheres (DMs), typically used for gel filtration chromatography. In addition DM beads can be used for affinity purification of glucosyltransferases (GTFs) from S...

OBJECTIVE: In this study we demonstrate that inorganic polyphosphate (polyP) exhibits a dual protective effect on teeth: it elicits a strong antibacterial effect against the cariogenic bacterium Streptococcus mutans and, in form of amorphous calcium polyP microparticles (size of 100-400nm), it efficiently reseals cracks/fissures in the tooth enamel and dentin. METHODS: Three different formulations of amorphous polyP microparticles (Ca-polyP, Zn-polyP and Sr-polyP) were prepared...

Metastatic tumors rarely occur in the oral cavity. The most common of the oral metastases are lung cancers in males, and breast and genital cancers in females. The most common primary tumor metastasis to the oral cavity is from the lung, kidney, liver, prostate, and colorectal cancers. The metastatic lesions are similar to oral lesions such as pyogenic granuloma, giant cell lesions, gingival polyps, hemangioma, peripheral fibroma, and adenoid squamous cell carcinoma. Therefore, the diagnosis of primary tumors is challenging...
