Multiple factors are involved in the pathogenesis of denture stomatitis, which increases the risk of tissue infection and inflammation. These factors include poor oral hygiene, trauma secondary to poorly fitting prostheses, resin porosity, and bacterial plaque accumulation. Our present review discusses the epidemiology, etiology, and treatment of denture stomatitis based on data from current studies in the literature. The prevalence of denture stomatitis is significantly variable among the different studies, as previously discussed. However, the cumulative incidence of denture stomatitis among their participants ranged between 17-77%. These hugely variable rates have been attributed to the nature of data collection, diagnostic criteria, sample size, and patient demographics. Studies also show that the condition is more prevalent among elderly females. However, not many studies have reported this correlation, indicating the need for future studies. Candida albicans infection is the primary parameter in the etiology and pathogenesis of the condition. However, other factors related to the patient (like status of immunological response) and dentures (like hygiene) were also reported. Therefore, the management of denture stomatitis should be based on applying adequate interventions. Besides, using antifungal medications is also necessary to eradicate organism.
Evidence indicates the effectiveness of these modalities in enhancing the quality of life for the affected patients. Furthermore, many previous investigations have assessed the survival rates of these modalities. Estimates show that implant-supported fixed partial dentures have survival rates of up to 10 years. However, it should be noted that many complications were reported following implantation procedures. These events can reduce the prognosis of the process and worsen the outcomes by decreasing the survival rate. The present literature review aims to provide evidence regarding dental implants' technical, biological, and mechanical complications. It should be noted that the incidence of these complications is generally decreasing based on the recent advance in the field. Adequate knowledge of the landmarks, careful treatment planning, proper case selection, obtaining a comprehensive history and information about implant procedure, and proper sterilization protocol are all different factors that can enhance the prognosis of the implant procedure. These can also reduce the frequency of the reported complications. Furthermore, these complications can be further reduced by being up to date with the recent advances and potential problem-solving research that usually provides adequate solutions that can reduce the frequency of these complications.
A pontic is an artificial tooth that substitutes a lost natural tooth, preserves its function, and typically fills the space left by the actual crown. Sanitary/hygienic and modified sanitary/hygienic designs do not contact the alveolar mucosa. On the other hand, ridge lap, modified ridge lap, ovate, modified ovate, and conical are designs that maintain contact with the mucosa. The ideal biological properties to be taken into consideration while designing pontics are periodontal health, access for oral hygiene, no food trapping and occlusal harmony. Accumulation of dental plaque has been implicated in the onset of gingival and periodontal disease as well as caries in the vicinity of the fixed restoration. The connection of the pontic to the supporting crowns must be constructed in such a way as to make a flushable area in the direction of the gingiva, in order to ensure that this area can be cleaned by toothbrushing and flossing but not the large triangular spaces that make it easy for food particles to cling. Modified ridge lap and ovate types, out of all the pontic shapes described below, exhibit convex cleansable faces. Ovate pontics are most effective for use in anterior regions, while the modified ridge lap design can be utilized predominantly in fixed partial denture designs posteriorly. The important etiological factor for gingivitis, periodontitis and peri-implantitis is bacterial colonization which is impacted by the individual's immunologic response and genetic predisposition in addition to dental care practices and pontic design. It is believed that no matter what the material of the pontic is, it must provide a highly polished intaglio surface to help floss slide through and make contact with the full base of the pontic in order to minimize plaque accumulation.
There are two types of tori, including torus palatinus and torus mandibularis. Evidence shows that these lesions usually progress slowly, and a spontaneous growth stop is usually another characteristic. Affected patients are usually asymptomatic. However, symptoms might be reported in edentulous patients and cases when the lesion is huge. In the present study, we elaborated on the causes, clinical patterns, and treatment of torus palatinus. The etiology of the condition is unclear, and different theories were reported in the literature, suggesting that the etiology of these cases is usually attributed to environmental and genetic predisposition. It has been defined as a benign tumor that presents in the maxillary bone and is usually asymptomatic. Therefore, the diagnosis of the condition is usually easy. However, it is recommended to conduct a differential diagnosis with other relevant malignant lesions in this area. Surgical interventions are not usually needed as the condition is usually discovered accidentally. However, in cases of tori-related prosthetic or functional discomfort, surgery can be conducted.
Dental implant is on rise in today’s time and era due to its importance in improving quality of life of patients. However, the success of the dental implant is significantly associated with individuals’ medical condition. Immunocompromised patients due to their weak immunity are considered sensitive for any type of surgery as it can result in various complications. Similarly in case of placing dental implants in immunocompromised patients’ supreme care and attention is needed in order to avoid risk and hazardous consequences. Oral and maxillofacial surgeons see an increasing number of patients with immunocompromised conditions in their daily practice due to better long-term health care and new indications for immunosuppressive therapy. The aim of this research is to review the available information about the dental implants in immunocompromised patients. Despite the fact that certain diseases are still considered risk factors in the effectiveness of dental implants in immunocompromised patients, there are few definite contradictions in this treatment option. As a result, disease control of risk factors, as well as personal risk assessment prior to dental implant treatment, may be considered more important than the disease or risk factor itself. Presence of various diseases can raise the risk of treatment failure or side effects in case of dental implant. Majority of the studies support dental implants as reliable and safe option under utmost care in immunocompromised patients however, the literature is quite divided and scarce in this regard and future research can be beneficial to yield better outcome and treatment strategies.
