Ankylosis of TMJ is the bony or fibrous fusion of articular components of joint. Ankylosis of TMJ can lead to facial deformity, which worsens with growth, having a negative influence on the psychological development of the patient. The present case report is of a 58-year-old female patient who reported with an inability to open mouth which was diagnosed as unilateral bony ankylosis. This case was treated by interposition gap arthroplasty followed by physiotherapy. Since TMJ ankylosis may go unnoticed for a long time, early intervention is mandatory for proper growth and function of the mandible.
The stability and retention of mandibular complete dentures have been a continuing problem. So, increment occur in the provision of implant-supported prosthesis in patients who are not able to tolerate conventional dentures. In this case report presents a simple and efficient method of fabrication of mandibular over denture retained by magnets in a patient in which mandibular residual ridge is severely resorbed with few remaining teeth and maxillary immediate denture. Mandibular over denture retained by magnets assembly consist of magnet and coping with keeper on remaining tooth structure since magnetic attachments can provide support, stability and retention.
A telescopic denture is a prosthesis which consists of two copings, one is a primary coping which is cemented to the abutments and a secondary coping which is attached to the prosthesis and it fits on the primary coping to increase the retention and stability of the prosthesis. For the patients with the badly broken teeth and without the ability of financial support telescopic denture is considered to be better option. The following case report is on telescopic hybrid prosthesis for maxillary arch. This case report describes the management of periodontally compromised teeth with removable hybrid prosthesis retained by telescopic crowns. This kind of prosthesis acts as a periodontal prosthesis and provides splinting action on the remaining teeth by equally distributing the occlusalforces. It thereby help in retaining the teeth longer.
Pediatric patients face many challenges to oral and periodontal health, including the placement of fixed orthodontic appliances during adolescence. One of the more recently identified periodontal pathogens is the organism Selenomonas noxia or S. noxia.
Objectives: Due to the paucity of evidence regarding the oral prevalence of S. noxia and the lack of evidence regarding the prevalence among pediatric orthodontic patients, the main objective of this project was to evaluate the oral prevalence in a dental school setting.
Methods: Using an existing saliva repository, twenty five (n=25) orthodontic saliva samples were selected from patients between the ages of 13 – 24 with twenty five (n=25) age-matched non-orthodontic saliva samples. DNA isolation was performed and screened with primers specific for S. noxia. Chi square analysis of demographic groups was performed and descriptive statistics of all results was reported.
Results: Screening of each DNA derived from each saliva sample for S. noxia revealed the presence of this pathogen in a subset of the study population. More specifically, the majority of samples screened (60% or n=30/50) did not harbor DNA for this organism. Most of the S. noxia-positive samples were derived from adults (65% or n=13/20) with more females (60%) than males, which were nearly equally divided among Orthodontic and non-Orthodontic patients.
Conclusions: This study provides novel information regarding the oral prevalence of S. noxia among both pediatric and young adult populations, with and without orthodontic brackets. These findings demonstrate that higher percentages of adults than pediatric patients harbor this organism, which does not appear strongly correlated with orthodontic treatment. These data add to the growing body of evidence that may suggest the presence of this organism may be associated with many additional factors that influence oral health and disease.
Aim and Objectives: To check the prevalence of facial form in dentuolous subjects in North Indian Population and to compare the relationship between inter-condylar distance and inter-canine distance which could help the dentist for the selection of maxillary anterior teeth.
Methods: A total of hundred dentate adults (20-35 years) with class 1 occlusion, having no attrition and with healthy temporomandibular joint were selected for the study. The facial form was evaluated with the Trubyte Tooth indicator. The width of the condlyes were measured between the beyron’s point with the help of facia type facebow . The width of the maxillary intercanine was measured between the tips of cuspids in both the patients mouth and the cast. Statistical analysis was performed to determine the relationship between the inter condylar width and the maxillary intercanine width.
Results: More than one third of patients had ovoid face form (35%) followed by square (33%), square tapering (18%) and tapering (14%). There was significant positive correlation between maxillary inter canine width and inter condylar width (r=0.62, p=0.0001). Both maxillary inter canine width and inter condylar width were significantly (p<0.05) higher among males than females.
Conclusion: when pre extraction records are not available, the result can help to determine the width of the artificial maxillary anterior teeth in edentulous patient.
