Introduction: Maxillary lateral incisor is a common congenitally missing tooth in the oral cavity. Maxillary lateral incisor is also the most common varying tooth in form than any other tooth. The objective of the study is to estimate the prevalence of congenitally missing maxillary lateral incisors and peg laterals in patients receiving orthodontic treatment. Materials & Method: This is a cross sectional retrospective study carried out among 204 orthodontic patients. Panoramic radiographs taken during the diagnostic procedure of orthodontic treatment was used to confirm the presence or absence of lateral incisors. The presence of peg laterals was determined by dental casts. Result: Prevalence of missing maxillary lateral incisors and peg laterals was found 2.5% and 3.9% respectively. Prevalence of missing lateral in male was 5.7% while among female no missing laterals were observed. Prevalence of peg laterals in male and female was 1.1% and 6% respectively. Among the missing lateral incisors, prevalence of bilaterally missing lateral incisors was 60% while prevalence of both right and left unilateral missing laterals was 20%. Among the peg laterals, bilateral peg laterals were present in 50% patients, followed by left unilateral 37.5% and right unilateral 12.5% peg laterals. Conclusion: The present study shows higher prevalence of peg laterals than missing lateral incisors. Prevalence of missing lateral incisors was higher in male and prevalence of peg laterals was higher in female. Prevalence of bilaterally missing laterals and bilateral peg laterals was higher than unilateral presentation.

“…It is very important on the part of clinicians to diagnose the type of teeth missing, the variations seen in relation to the gender affected, the etiology behind, either due to congenital absence of the related tooth buds or due to impactions and the type of skeletal base present and accordingly plan the treatment. [ 25 26 27 28 ] Arandi and Mustafa,[ 29 ] likewise, conducted a study on 2662 dental patients in Palestine who were evaluated for the prevalence of congenitally missing lateral incisors and found 1.91% of the subjects with unilateral agenesis accounting for up to 66.6% of the total cases. In addition, around 79% of the unilateral cases were on the left side while 21% were on the right side.…”

OBJECTIVE: To determine the frequency of congenitally missing maxillary lateral incisors (LIs) and to find out its variability in relation to gender. MATERIALS AND METHODS: A retrospective study was carried out between January 2017 and December 2017. Orthopantomographs (OPGs) and lateral cephalographs record search of all orthodontic adolescent patients aged 12 to 18 years were taken from the archival records of the department. Orthopantomographs helped to diagnose the presence of unilateral/bilateral maxillary lateral incisors while the ANB angle was calculated from the lateral cephalographs to divide the subjects into various skeletal malocclusions. STATISTICAL ANALYSIS USED: The statistical analysis was done using the Statistical Package for Social Sciences (SPSS version 17.0). The frequencies were compared with the help of the Chi-square test. P <0.05 was considered statistically significant. RESULTS: The frequency of missing upper laterals among the male patients was 0.9%, however, 2.8% of the female patients were having missing maxillary lateral incisors. Based on gender, 62.16% had a bilateral expression of missing upper laterals, 16.21% had left unilateral expression, and 21.62% had right unilateral expression. Furthermore, skeletal class I malocclusion had a prevalence of 54.16% of bilateral missing lateral incisors in upper arch as compared to 40% of left unilateral expression and 37.5% of right unilateral expression whereas in skeletal class II malocclusion, the prevalence of right unilateral expression was 37.5% as compared to bilateral expression which was 33.33%. The left unilateral expression in skeletal class II malocclusion was found to be only 20%. The highest prevalence of missing laterals in skeletal class III malocclusion was left unilateral expression which was around 40%. The prevalence of right unilateral expression was 25% whereas the bilateral absence of upper laterals in skeletal class III malocclusion was 12.5%. CONCLUSION: The prevalence rate for congenitally missing upper lateral incisors in the orthodontic adolescent population aged 12 to 18 years was found to be 3.77% in the present study while females were found to have a greater percentage of agenesis of the upper lateral incisors (2.8%) as compared to the males (0.9%).

“…Maxillary lateral incisors agenesis may cause a variety of esthetic and functional problems; their absence may cause a diastema between the central incisors, spacing between permanent incisor and canine, mesial migration of canines, midline shift in case of a unilateral missing tooth. 5,9 The options available to the clinician are the possibility of space closure with mesial repositioning of canines, followed by teeth recontouring; or a combination of space opening and prosthetic replacement of the missing lateral tooth. 7 Missing teeth are significant enough reasons for extensive oral rehabilitation requiring orthodontic, restorative and prosthodontic procedures at the dental clinic, as various combinations of poor aesthetics and occlusal dysfunction are presented by the patients.…”

The maxillary lateral incisor is the second most common congenitally absent tooth. This is a case of a 25-year-old with maxillary lateral incisors agenesis, multiple maxillary anterior diastema. Pre-adjusted technique was used, gingivectomy and frenectomy to release tooth movement. Patient’s profile was straight, interdental relationship was class I, enlarged space of maxillary lateral incisors, space was replaced by prostheses. The treatment of maxillary lateral incisors agenesis responsible for orthodontic, periodontic and prosthodontic achieved a pleasant aesthetic and function.
