Exploring the link between poor oral hygiene and mesh infection after hernia repair: a systematic review and proposed best practices.

BACKGROUND: There is a reasonable body of evidence around oral/dental health and implant infection in orthopaedic and cardiovascular surgery. Another large area of surgical practice associated with a permanent implant is mesh hernia repair. This study aimed to review the evidence around oral/dental health and mesh infection. METHODS: The research protocol was registered in PROSPERO (CRD42022334530). A systematic review of the literature was undertaken according to the PRISMA 2020 statement. The initial search identified 582 publications. A further four papers were identified from references. After a review by title and abstract, 40 papers were read in full text. Fourteen publications were included in the final review, and a total of 47,486 patients were included. RESULTS: There is no published evidence investigating the state of oral hygiene/health and the risk of mesh infection or other infections in hernia surgery. Improvement in oral hygiene/health can reduce surgical site infection and implant infection in colorectal, gastric, liver, orthopaedic and cardiovascular surgery. Poor oral hygiene/health is associated with a large increase in oral bacteria and bacteraemia in everyday activities such as when chewing or brushing teeth. Antibiotic prophylaxis does not appear to be necessary before invasive dental care in patients with an implant. CONCLUSION: Good oral hygiene and oral health is a strong public health message. The effect of poor oral hygiene on mesh infection and other complications of mesh hernia repair is unknown. While research is clearly needed in this area, extrapolating from evidence in other areas of surgery where implants are used, good oral hygiene/health should be encouraged amongst hernia patients both prior to and after their surgery.

Patients with special needs within treatment under general anesthesia - meta-analysis.

The study evaluates results obtained from the documentation of patients with special needs, who have undergone treatment under general anesthesia at the pediatric dentistry department. DMFT (decayed, missing, filled teeth) was used for comparison. A sample of 1,836 children from our dental clinic was evaluated. The sample was divided into two groups - special patient and disabled patient populations. A group of 5 years old children was chosen on the bases of WHO guidelines for the setting of the oral health status. A descriptive statistical analysis of the mean standard deviation was conducted with a focus on three factors: sex, age and year. A questionnaire was prepared to compare the oral health habits in the families of the patients. A literary review was conducted to compare the results with other studies from various countries. The meta-analysis using the software MedCalc was done. The DMFT of the patient was counted (disabled DMFT 11.05 - SD 4.82, special patient population 8.8 - SD 3.7) and the descriptive statistics mean standard deviation was calculated. The significant difference between the DMFT of disabled patient and special patient population was exerted (p<0.00003). It was statistically evaluated that the data gained from the studies and from the WHO as population average for 5 years old children are situated under the minimum limit of the confidence interval for our study. The meta-analysis confirmed the hypothesis that oral health status of the special needs children is worse than in other countries.

Nasal prosthesis supported with self-tapping implants with bioactive surface--a case report.

Nasal prosthesis using dental implants and magnetic abutments is a method of choice in replacement of missing hard and soft facial tissues. Nose form, coloration, and texture must be as indiscernible from the surrounding natural tissues as possible. Rehabilitation efforts can be successful only when patients can appear in public without fear of attracting unwanted attention. This case report evaluates on a step-by-step basis the materials and methods including implants insertion.

Overdenture - implants versus teeth - quality of life and objective therapy evaluation.

An overdenture is a complete or removable partial denture that has one or more tooth roots or implants to provide a support. The study compares two types of prosthodontic treatment - overdenture supported by remained own teeth with ball attachments and that held by implants. The cohort of 35 patients (recall from 1 to 5 years) was evaluated. When subjectively and objectively assessed no significant difference between both groups was observed.

OBJECTIVES: To identify support of structured data entry for electronic health record application in forensic dentistry. METHODS: The methods of structuring information in dentistry are described and validation of structured data entry in electronic health records for forensic dentistry is performed on several real cases with the interactive DentCross component. The connection of this component to MUDR and MUDRLite electronic health records is described. RESULTS: The use of the electronic health record MUDRLite and the interactive DentCross component to collect dental information required by standardized Disaster Victim Identification Form by Interpol for possible victim identification is shown. CONCLUSIONS: The analysis of structured data entry for dentistry using the DentCross component connected to an electronic health record showed the practical ability of the DentCross component to deliver a real service to dental care and the ability to support the identification of a person in forensic dentistry.

Giant cell reparative granuloma in the mandible--case report and review of the literature.

OBJECTIVE: Central giant cell granuloma (GCG) is defined as an intraosseous lesion consisting of cellular fibrous tissue containing multiple foci of hemorrhage, aggregations of multinucleated giant cells. Peripheral GCG is a reactive exophytic lesion occurring on the gingiva and alveolar ridge originating from the periosteum or periodontal membrane, usually as a result of local irritating factors. STUDY DESIGN: The case report evaluated long-term therapy of giant cell granuloma. A 9-year-old boy generally healthy was admitted to our clinic with a swelling in the frontal area of mandible. Giant cell granuloma was detected. Surgical curettage was applied. After 3 years of the operation, the recurrence was seen during the physical examination. The new GCG was removed. The prosthetic rehabilitation including implants insertion (18-year-old adult patient) finished treatment. RESULTS: Three-year recall confirmed the stability of treatment. CONCLUSION: Esthetical and functional therapy is of great importance in the patient's rehabilitation.

Forensic dentistry--identification from the dentist's point of view.

The paper deals with an identification of missing persons based on a dental documentation. The procedure of the identification is presented in two case reports with a new possibility of electronic imaging called Dental Cross in comparison with classical dental documentation, which is officially used for identification of the missing persons by Interpol.

Influence of hydroxyapatite crystallinity on the growth of keratinocytes.

Dental implantology is a field, which has made a great progression recently. The main task nowadays is to shorten the healing period and so improve the comfort for the patients. One possibility how to full fil this task is to coat the surface of the implant. Very promising material seems to be hydroxyapatite, which is a natural component of human body and suitable method is the pulsed laser deposition. In our study we tried to evaluate difference between crystalline and amorphous hydroxyapatite coated dental implants from the biological point of view. We found that the cells were able to adhere to all of our studied samples. The worst proliferation of fibroblasts was found on the amorphous coating, whereas the adhesion was fully comparable with other surfaces. The level of keratinocyte differentiation was the same on both of the studied surfaces.

Study of laser created ZRO2 and hydroxyapatite/ZrO2 films for implantology.

Thin films of ZrO2 and hydroxyapatite/ZrO2 were created by excimer laser ablation on Ti6Al4V substrates. ZrO2 layers were fabricated in vacuum by KrF laser at various substrate temperatures and hydroxyapatite (HA) layers were fabricated in water vapor ambient by ArF laser and in water vapor/argon ambient by KrF excimer laser. Film properties were evaluated by XRD, SEM and WDX methods. The test of mechanical adhesion was proceeded on ZrO2 films. XRD analysis proved the presence of amorphous or crystalline HA in the deposited films. SEM method demonstrated smooth surface covered by droplets for both HA and ZrO2 films. Ca/P ratio of the HA films is higher than that of the natural HA and is within the range of 2.8-3.0. The HA/ZrO2 and ZrO2 samples were tested in vitro for cytotoxicity. The best results were received by the HA/ZrO2 samples in the test of cytotoxicity. Fibroblasts cultivating with HA/ZrO2 samples exhibited subconfluent and confluent growth and showed fibronectin homogenously.

Denture reconstruction of the edentulous upper jaw in cleft palate using implants--clinical report.

OBJECTIVE: Early prosthodontic therapy (usually at around 18 years of age) often leads to early loss of teeth and in extreme cases to complete loss of dentition at between 40 and 50 years of age. PATIENTS: This report describes the clinical features of two middle-aged cleft patients. Edentulous maxilla with cleft defect was treated with 6 implants supported by fixed appliance. RESULTS: Treatment of the whole dental arch on the basis of implants is currently frequently used as it provides a possibility of thorough functional and aesthetic therapy to a patient. The biomechanics of the reconstruction enables individual adjustment of the shape of the dental arch. CONCLUSIONS: The problem in cleft patients involves other diameter relations in the dental arch caused by the defect alone or also by affecting the growth of the maxillary segment by surgery. A potentially removable framework is therefore the main method of choice because the position of the implants must be prosthetically modified.

Shape and size of dental arch--a five-year prospective study.

OBJECTIVES: The diagnostic procedure commences with the initial examination, during which a number of individual findings of the occlusion or malocclusion are clarified [1]. The objective is to describe the morphological and functional characteristics on each patient using specific guidelines, and then to provide a prognosis of the therapy. Upper and lower arch compression in first premolars and molars area was visible before treatment. METHODS: A special device (Czech technical university research prototype) was prepared for this purpose. The optical head contains a digital color camera. The front of the optical head consists of a removable prism which is put into the mouth. The findings can display live images from the camera, which can be archived on a PC. The device captured and geometrically calibrated images permitting comparison of several different dental casts. RESULTS: In the first part of this study 792 sets of study plaster casts were screened. Measurements of dental arch width between reference points of canines, first premolars and first molars were made: upper jaw: men: 3-3-35.1 mm (SE 0.13); 4-4-37.5 mm (SE 0.13); 6-6-48.1 mm (SE 0.19); women: 3-3-33.4 mm (SE 0.13); 4-4-35.6 mm (SE 0.15); 6-6-46.7 mm (SE 0.19). The second part concerns the group of 36 patients which is different from the 792 controls. There were studied changes between initial, post-treatment and post-retention alignment of upper and lower dental arch. CONCLUSIONS: Geometrically calibrated images help compare several different steps of the treatment and show a significant difference between patients before and after treatment.
