Prevalence of malocclusion and orthodontic treatment needs among 12–15-year-old schoolchildren of fishermen of Kutch coast, Gujarat, India

Background: Malocclusion is one of the most common dental problems in mankind. Planning orthodontic treatment as well as an interceptive approach within a public health system requires information on the prevalence of malocclusions.Aim: The aim of the study was to assess the prevalence of malocclusion and orthodontic treatment needs among 12–15-year-old school children of fishermen of Kutch coast, Gujarat, India.Materials and methods: A cross-sectional descriptive survey was conducted among 947 school children offishermen of Kutch coast, Gujarat, India aged 12–15 years. The prevalence of malocclusion and orthodontic treatment needs was assessed using Dental Aesthetic Index. General information on demographic data was also recorded. A c2 test, analysis of variance (ANOVA) and Sheffe’s test were employed for statistical analysis.Results: Malocclusion and orthodontic treatment need was reported among 33.4% of the participants. Younger age group and female gender had significantly greater treatment need. Males and older age groups had significantly lesser prevalence of anterior crowding and largest anterior maxillary irregularity.Conclusions: Orthodontic treatment need among 33.4% calls for developing school based oral health promotion programmes for children with an inculcation of orthodontic treatment and educational programmes for parents (fishermen) addressing prevention and early interceptive treatment of malocclusion

Ormocer: An aesthetic direct restorative material; An in vitro study comparing the marginal sealing ability of organically modified ceramics and a hybrid composite using an ormocer-based bonding agent and a conventional fifth-generation bonding agent

Aims and Objectives : To compare the marginal sealing ability of ormocer with a hybrid composite using an ormocer based bonding agent and a conventional fifth generation bonding agent. Materials and Methods : Fifty four human premolars were randomly distributed into four test groups of 12 teeth each and two control groups of 3 teeth each. Class I occlusal preparation of 1.5 mm depth were made in each tooth. These were restored using the adhesive and restorative material according to the group. The restorations were finished using a standard composite finishing and polishing kit. Thermocycling between 5 o C and 55 o C was carried out. Having blocked the root apex and the entire tooth surface except 1 mm around the restoration margin, the teeth were immersed in 2% methylene blue for 48 hours, after which the dye penetration through the margins of each sample was studied under a stereomicroscope. Results and Discussion : Group IV (Admira with Admira Bond) showed the minimum marginal leakage with a mean of 0.200 mm. Four samples in this group showed no microleakage at all and a maximum of 0.400 mm was seen in one sample. Group II (Spectrum TPH with Admira Bond) showed the maximum leakage with a mean of 0.433 mm. One sample showed as much as 1.00 mm of microleakage. Admira when used with Admira Bond showed lesser microleakage than Spectrum TPH used with Prime & Bond NT, the difference being statistically insignificant

Hoffa fracture associated with femoral shaft and proximal tibial fractures: report of two cases

【Abstract】 Solitary coronal shear fractures of femo-ral condyle, such as Hoffa’s fracture, are usually associated with supracondylar or intercondylar fractures of the femur. These fractures are rare and seen in the context of high energy mechanism leading to multiple injuries; therefore a thorough workup of the patient is required to rule out other significant injuries. Hoffa’s fracture associated with femo-ral shaft and proximal tibial fractures is extremely rare and no such injury has been reported previously. We report two such cases which were managed with standard operative fixation techniques and demonstrated good to excellent func-tional outcome after a follow-up of one year. This report emphasizes that high index of suspicion is required for di-agnosis of these injuries and a thorough workup is manda-tory to rule out other associated injuries. We also propose a possible mechanism of injury. Key words: Femoral fractures; Tibial fractures; Fracture fixatio

A cephalometric analysis to establish a correlation of different ridge relations to three levels of camper's line in edentulous patients: An in vivo study

Aim: This study was undertaken with an aim to establish a relationship between normognathic (Class I), retrognathic (Class II), and prognathic (Class III) ridge relation and superior, middle, and inferior levels of the ala-tragus line in edentulous individuals, by utilizing arbitrary and cephalometric methods. Methodology: Ninety edentulous male patients were selected for the study, and after establishing tentative jaw relation, radiopaque ball bearings were attached on three levels of the tragus and inferior part of the ala of the nose. Furthermore, orthodontic wire was attached to maxillary occlusal rims. Lateral cephalometric radiographs were taken, and tracings were carried out to compare and to evaluate the cephalometrically derived ridge relations with that of the visually analyzed ridge relations based on the mounted casts in relation to the ala-tragus line. The results obtained were statistically analyzed using one-way ANOVA test, and multiple comparisons were carried out using the Bonferroni tests. The interoperator variability for obtaining ridge relations using visual analysis and the cephalometrically obtained ridge relations were analyzed using the Kappa statistics. Results: The result obtained states that 78 participants out of 90 participants are in total agreement with the Kappa value of 0.8. Conclusion: The study concluded that for Class I and Class III, the inferior part of the tragus forming the ala-tragus line, and for Class II, the middle part of the tragus should be considered for establishing the occlusal plane
