Papillon-Lefevre Syndrome (PLS) is a autosomal recessive genetic disorder. The prevalence of this disorder has been reported to be 1 to 4 per million in the general population. The prime features of PLS include palmar-plantar hyperkeratosis along with premature loss of deciduous and permanent teeth due to aggressive periodontitis. Radiological feature involves severe destruction of alveolar bone giving teeth a typical “floating in air” appearance along with intra-cranial calcifications. Clinical findings of disease specific dermatologic manifestations and periodontal involvement forms the framework of the diagnosis. Clinical significance: As PLS involves severe irreparable destruction of alveolar bone and tooth loss, both dental clinicians and dermatologists opinion is required for both initial and long term management of this disease followed by psychological counselling.

Aim: The purpose of this study was to examine the strength of the bonding between orthodontic brackets and different orthodontic adhesives. Materials and methods: To achieve this, the researchers selected 120 extracted premolars and divided them into four groups randomly. Then, one of the three adhesives, Transbond XT, Bracepaste, or Heliosit, was used to join the brackets together. After bonding, the force needed to remove the brackets was tested, and the amount of adhesive that remained on the tooth surface was also noted (referred to as the adhesive remnant index or ARI). Results: The results showed that Transbond XT had an average bond strength of 18.05 ± 5.6 MPa, Bracepaste had an average bond strength of 16.6 ± 5.1 MPa, and Heliosit had an average bond strength of 16.2 ± 4 MPa. The average bond strength and ARI scores for Transbond XT and Bracepaste were similar at 11.10 MPa. The study found that the light-cured composite adhesives provided the strongest bond and left the tooth surface smoother and cleaner. Conclusion: In conclusion, the study presented significant information about the impact on the enamel surface as well as the strength of the bond between orthodontic brackets and different adhesives.
