Abstract
Background. Dental hypersensitivity is due to the exposure of the dentin layer after wear of enamel or cementum, exposing the dentinal tubules and the nerve endings of odontoblasts within these tubules. The present study aimed to assess the factors related to dental hypersensitivity in individuals with cleft lip and palate and the most common therapy received. Methods. The medical records of 536 patients with cleft lip and/or palate (281 males, 255 females) with a mean age of 18 were analyzed in a single center. The inclusion criterion was patients reporting dental hypersensitivity from May 2015 to October 2019. The origin of dental hypersensitivity was evaluated considering orthodontic movement, periodontal diseases, and reversible and irreversible pulpitis. The therapy indicated by the dental professionals for dental hypersensitivity were recorded. Descriptive statistics were performed. Results. Of 61 teeth with dental hypersensitivity, 10 were attributed to orthodontic movement, 21 to periodontal problems, 27 to reversible pulpitis, and three to irreversible pulpitis. The most used therapies were the application of fluoride varnish and prophylaxis, dentifrice indication for dental sensitivity, free gingival grafts, pulpectomy, desensitizing agent application, conservative endodontic treatment (direct pulp protection), and restoration of non-carious cervical lesions. Conclusion. Reversible pulpitis was the most prevalent etiologic factor of dental hypersensitivity in individuals with cleft lip and palate. Dentifrices for dental sensitivity and fluoride varnish application were frequently recommended.
Highlights
Orofacial clefts are identified as congenital defects that occur during intrauterine life, precisely during the 8th week and the 12th week gestational age, when the palatine cleft occurs.[1]
A total of 536 medical records were analyzed, of which 61 individuals had some type of dental hypersensitivity
Dental hypersensitivity related to reversible pulpitis exhibited a percentage of 44%, the percentage related to periodontal problems was 35%, with 16% related to orthodontic movement and 5% related to irreversible
Summary
Orofacial clefts are identified as congenital defects that occur during intrauterine life, precisely during the 8th week (cleft lip and alveolar flange) and the 12th week gestational age, when the palatine cleft occurs.[1] When the hygiene of these individuals is poor, they are susceptible to dental caries and all the harm it causes to the oral environment When these patients are not assisted by a dentist, and interventions are not performed, the bacteria and their byproducts reach the pulp, and the tooth in question requires endodontic intervention.[2] The hydrodynamic theory is the most widely accepted hypothesis, and according to this theory, the basis for the transmission of sensation is the movement of fluids in the dentinal tubules.[3] It is suggested that dental hypersensitivity would be an inflammatory response in the pulp. Dentifrices for dental sensitivity and fluoride varnish application were frequently recommended
