| Summary: | Tooth agenenesis is reduction of tooth number caused by congenitally failure of tooth development causing hypodontia and
oligodontia. The prevalence, pattern and distribution are varies by populations. The aim of this study was to identify the pattern
and distribution of tooth agenesis in permanent dentition among Malaysian population. Patients were in the range of 12 until 60
years old has missing average of 2 teeth missing. Excluding third molar, the prevalence of population under study was 1.005%.
Mandibular and/or lateral incisors (28%) were identified as the most common missing tooth. There were no significant difference
between missing tooth between male and female (p=0.265). More missing teeth were observed at maxilla jaw (54.67%), right
side (54.67%), posterior region (53.33%) and missing unilaterally (71.42%). Some tooth anomalies such as peg shaped tooth
(8.57%) and microdontia (5.71%) also presented. In conclusion, the prevalence studied population was lower than normal range
and previous studies conducted in Malaysian but still may presumably represent group of population under study, while mild
hypodontia is considered as the most common type of tooth agenesis. The most common missing tooth is lateral incisors whereas
mild hypondontia is identified the most common tooth agenesis. |
