Cerebral palsy (CP) is a set of nonprogressive neuromuscular disorders caused by defects in the developing fetal brain. The aim of this study is to investigate the prevalence and distribution of various dental conditions including dental caries and periodontitis among individuals with CP who receive care at the Rancho Los Amigos National Rehabilitation Center dental clinic. Medical records of 478 patients between the ages of 3 and 78 years were reviewed. Patients were divided into four age groups: 3-20, 21-35, 36-55, and 56 and above year old. Data related to their dental conditions including caries, periodontitis, and other oral diseases were assessed. Statistical analyses were conducted to evaluate the correlations between these oral diseases and age, gender, ethnicity as well as their living conditions (home or group home). The 36-55-year-old age group displayed significantly more caries and periodontitis than any other age groups. Individuals aged 3-20 years showed a significantly lower rate of periodontitis and caries. There was no significant association between gender and race with these outcome variables but there was a correlation between these variables and living conditions. Differences in oral health exist among people with CP from different age groups and living conditions. These findings suggest that there is a dire need for more oral hygiene training and education for the care givers. Dental schools should better prepare their graduates to meet the treatment demands of individuals with special healthcare needs.

Results suggest that tooth wear is negatively related to quality of life.

Objectives This prospective comparative clinical trial study aims to investigate the postoperative stability of the double-jaw surgical treatment of skeletal Class III deformity and to compare two different mandibular surgical approaches. The study goal is to locate the relapsing direction of both the maxilla and the distal segment after either bilateral sagittal split ramus osteotomy (BSSO), or intraoral vertical ramus osteotomy (IVRO). Methods Twenty-two (22) patients with skeletal Class III were included in this study. The patients were treated with double-jaw surgery by LeFort I osteotomy combined with either BSSO or IVRO. Lateral cephalograms taken before (T0), immediately after (T1), and 1 year after the surgery (T2) were studied and analyzed. Result The mean mandibular setback and maxillary advancement in the BSSO group were 6.22 mm at B Point and 2.93 mm at A point with relapse percentages of 24.9 and 26.6%, respectively, while the mean mandibular setback and maxillary advancement in the IVRO group were 2.55 mm at B point and 5.89 mm at A point with relapse percentages of 22.1 and 23.5%, respectively. The magnitude of the setback significantly accounted for the relapse. Conclusion One-year follow-up revealed that the maxilla would be displaced posteriorly and inferiorly in both groups. Regarding the direction of the mandibular relapse, the mandible in BSSO surgical group was displaced forward and upward, while in IVRO surgical group, the directions were completely different in which the mandible is displaced backward and downward.
