title: Comparison of periodontal status among patients with cleft lip, cleft palate, and cleft lip along with a cleft in palate and alveolus.
abstract: OBJECTIVE
  A healthy periodontium is an important prerequisite for unhindered dentition and long-term oral health. In cleft subjects, especially in those with cleft lip, alveolus and palate (CLAP), maintenance of oral hygiene is a difficult task for the patients because of the patent oro-nasal communication. Crowding of teeth in cleft patients is a common finding, especially in those with CLAP and those with cleft palate (CP). In the case of multiple tooth-malpositions, transverse deficiency, arch length deficiency and primary cross-bite; periodontal trauma increases and is detrimental to periodontal health. According to literature, a critical periodontal situation was found in patients with CLAP. Hence a study was conducted to analyze the periodontal status of patients with cleft lip (CL); those with cleft palate; and those with cleft lip, alveolus and palate.
  
  
  METHODS
  The present study consisted of 60 cleft subjects divided into 3 groups: those with cleft lip; those with cleft palate; and those with cleft lip, alveolus and palate. Subjects with permanent dentition were selected, and the clinical examination included determination of oral hygiene status using Oral Hygiene Index - Simplified (OHI-S) index and periodontal status using community periodontal index (CPI).
  
  
  RESULTS
  Statistically significant increase in the periodontal disease in the CLAP group as compared with the other 2 groups, and the oral hygiene was seen to be generally poor with the CLAP group.
  
  
  CONCLUSIONS
  Individuals with clefts are more prone to periodontal disease due to the presence of cleft, which causes retention of food in the defect sites and inability to maintain good oral hygiene; but the severity of periodontal disease is more if the defect is large and involving the lip, alveolus and palate.
