Management of an impacted and transposed maxillary canine

Maxillary canine-lateral incisor transposition is a relatively rare anomaly, with both dental and facial esthetic implications. This is a case report of a maxillary canine-lateral incisor transposition that was successfully treated by surgical-orthodontic treatment followed by esthetic reshaping of the involved teeth

Effect of fluoride varnish on <i>Streptococcus mutans</i> counts in plaque of caries-free children using dentocult SM strip mutans test: A randomized controlled triple blind study

Dental caries is one of the most prevalent infectious diseases and although of multifactorial origin, <i> Streptococcus mutans</i> is considered the chief pathogen in its development. Fluoride is one of the most effective agents used for the reduction of dental caries apart from oral hygiene maintenance. <b> Aims:</b> The aim of this study was to estimate the counts of <i> Streptococcus mutans</i> and to evaluate the effect of Fluor Protector fluoride varnish on these counts in the plaque of caries-free children using Dentocult SM Strip Mutans. <b> Materials and Methods:</b> Thirty caries-free subjects were selected for the study based on the information obtained from a questionnaire and were randomly assigned to the control group consisting of ten subjects and the study group consisting of twenty subjects. Plaque samples were collected on the strips from the Dentocult SM kit and after incubation, the presence of <i> Streptococcus mutans</i> was evaluated using the manufacturer&#x2032;s chart. The study group was subjected to a Fluor Protector fluoride varnish application following which the samples were collected again after 24 hours. <b> Results:</b> The average <i> Streptococcus mutan</i> s counts in the primary dentition of caries-free children before and after the application of Fluor Protector fluoride varnish were 10⁴ -10⁵ colony forming units (CFU)/ml and &lt; 10⁴ CFU/ml respectively. <b> Conclusion: </b> The results showed that the study group had a statistically significant reduction in the plaque <i> Streptococcus mutans </i> counts than the control group

Correction of class III malocclusion using modified tandem appliance-two case reports

Skeletal discrepancies in growing children can have great physical and psychological impact on their appearance. These deformities require orthopedic correction at an appropriate age to avoid future extensive management. Managing a midfacial deficiency or true mandibular prognathism is perhaps the most challenging situation for the clinician. Many orthopedic appliances like chin cup, facemask, and so on have been advocated to correct class III malocclusion. The major problems with these appliances are physical appearance, skin irritation from the anchorage pads and hence, less patient compliance. We present management of class III malocclusion in two children with modified tandem appliance (MTA), which is an intraoral appliance, with no extraoral anchorage, and has better patient compliance and cooperation

The relationship between a primary maxillary incisor with a talon cusp and the permanent successor: A study of 57 cases

Background. Most reported cases of talon cusps in the primary dentition have been on the maxillary central incisors and. the permanent successors have remained unaffected. Four of the five reported cases on a maxillary lateral incisor, however, have been associated with a supernumerary permanent successor. Aim. This paper describes the relationship between the presence of talon cusps on a primary maxillary incisor, and the morphology and number of the permanent successors in a opulation of Chinese children.Design. The dental records of children diagnosed with a talon cusp on a primary incisor were retrieved for review. The diagnoses took place in a regional school dental clinic in Hong Kong between April 2002 and August 2005. Results. Fifty-eight primary maxillary incisors with talon cusps were found. When the central incisors were involved, 32 of the 35 (91.4%) underlying permanent successors were not found to be associated with any odontogenic abnormalities. When the lateral incisors were involved, however, 18 of the 23 cases (78.3%) showed odontogenic abnormalities, 14 of which were associated with supernumerary teeth. Conclusions. The present study shows that, when there is a talon cusp on a primary maxillary lateral incisor, a high proportion of the underlying permanent successors can be expected to exhibit odontogenic abnormalities. © 2007 BSPD, IAPD and Blackwell Publishing Ltd.link_to_subscribed_fulltex
