Introduction: Dens invaginatus (DI) is a rare developmental malformation occurring as a result of the invagination of the enamel organ. The aetiology of this anomaly remains unclear. However, the knowledge of classification and anatomical variations of teeth with DI are very significant for the best treatment. The most commonly affected tooth is the maxillary lateral incisor. The treatment varies depending on the severity of the case. This paper presents a case of DI on an immature permanent maxillary central incisor.
Case Report: An eight-year-old healthy Malay girl came to the paediatric dental clinic for regular dental check-up. The intra-oral examination revealed presence of deep pit on the permanent maxillary left central incisor. The radiograph showed the presence of invaginatus confined within the crown indicating DI. The tooth partially erupted with the open apex. The best treatment option was the placement of fissure sealant on the affected tooth.
Conclusions: A thorough examination, early diagnosis, and proper treatment are important to prevent any dental complication that may associate with this anomaly.
Introduction: Nowadays, Chewing Gum is one of the frequent habits among people. The purpose of this study was to compare the effect of two types of chewing gums (with and without sugar) on dental plaque accumulation in the lack of oral hygiene measures.
Materials and Methods: In this descriptive cross-sectional study, plaque accumulation during three 4-day periods (with two-week interval) was recorded (Sillness & LÖe Index) in a group of 20 patients in the absence of routine oral hygiene methods. The patients were asked to chew sugar-free Gum (Trident) during the first 4-day period and sugar-containing Gum (Dubble Bubble) during the second 4-day period and stop chewing during the third period. Participants were asked to chew five gum sticks daily after meals for about twenty minutes. The data were statistically analyzed using One Way ANOVA and LSD full form tests.
Results: The results showed that both sugar-free and sugar-containing gums reduced the amount of plaque (P<0.001). The comparison of the mean dental plaque accumulation between the two groups indicated that the effect of the sugar-free gum was more significant than that of the sugar-containing one (P<0.001).
Conclusion: Although sugar-free gum is more effective than sugared gum on reducing dental plaque accumulation, chewing sugar-containing gum also decreases the level of dental plaque.
The present study analysed 10 cases of paediatric mandibular fractures, epidemiology and treatment strategies. A systematic retrospective analysis of 10 paediatric patients who had undergone surgery for maxillofacial trauma in our department of oral and maxillofacial surgery, PMNM Dental College and hospital, North Karnataka were included in this study. The data collected was analysed to determine the prevalence of mandibular fracture with respect to particular age group, sex, etiology, commonest fracture site and the method of management. The most common is parasymphysis fracture which account for 61.53% of cases followed by condylar fracture (23.07%). Multiple fractures (20%) are less common. Pediatric mandibular fractures (5%) are rare compared to adults. The reasons cited include relatively small volume of facial mass compared to calvarium, resilience of paediatric skeleton and the protected environment in which the children live. Mangement of pediatric mandibular fractures is certainly a dilemma to surgeons due to developing dentition, growing mandible, deficit of co-operation due to age, future complications, and compromise in esthetics and function which may develop.
Much has been spoken about secondary impression in making complete denture. In fact, it must exploit all the positive landmarks enhancing the stability.
Generally, an immediate recording of the denture support area is possible while the fibromucosa is adherent and firm, but uncommonly, due to anatomical particularities such as hyperplastic Schroder area, the impression requires specific technical modifications.
Indeed, this glandular zone, defined as an overextended non-inflammatory palatal papillary hyperplasia require an impression using selective pressure technique while the surgical option is impractical.
The aim of this paper is to explain the principles of this method through a case report and detail the clinical steps of the denture fabrication enhancing the comfort and the fit of the prosthetic rehabilitation.
Purpose: The purpose of the study is to evaluate changing trends in mandibular fractures over the last 10 year period. Mandible the largest and strongest bone is the second most commonly involved bone in trauma. Also there is association between etiology and site of fracture. With the advent of high speed machineries and well developed roads, multiple fractures become more prevalent. Also there is association between the multiple fracture sites. This study helps to evaluate common fracture site, age and sex prevalence, etiology etc.
Methods: A retrospective analysis of patients operated for maxillofacial trauma over a period of last 10 years was done. Detailed information regarding their age, sex, etiology, site of fracture etc are collected and analysed.
Results: Most commonly affected are males of age 21 to 30 years. Parasymphysis is the most commonly involved single site and in multiple fracture, most common combination is parasymphysis and condyle.
Conclusion: Epidemological studies are important to know the prevalance, to identify particular etiology and to formulate ideal preventive measures. Also multiple fractures are becoming more prevalant, so it is important for the clinician to do thorough examination not to miss out multiple findings and to provide appropriate care.
