Maxillary dental arch affected by different sleep positions in unilateral complete cleft lip and palate infants
Insights
Infants sleeping in the prone position showed narrower maxillary arch and cleft width compared to those in the supine position. This finding highlights the impact of infant sleep position on dental arch development in unilateral complete cleft lip and palate cases.
Area of Science:
- Craniofacial development
- Pediatric dentistry
- Orthodontics
Background:
- The dental arch exhibits adaptive and compensatory growth capabilities.
- Understanding factors influencing dental arch development in infants is crucial for early intervention.
Purpose of the Study:
- To investigate the relationship between infant sleep position and maxillary dental arch development.
- To compare arch dimension changes in infants with unilateral complete cleft lip and palate based on sleep position.
Main Methods:
- A cohort of 42 infants (under 1 month) with unilateral complete cleft lip and palate were divided into prone (16) and supine (26) sleep groups.
- Maxillary dental impressions were taken initially and pre-cheiloplasty.
- Ten arch dimensions were measured on dental casts, comparing longitudinal changes between sleep position groups.
Main Results:
- Statistically significant differences in growth rates were observed for intercanine width, intertuberosity width, alveolar cleft width, anterior cleft width, and posterior cleft width.
- Infants in the prone sleep position demonstrated a tendency towards narrower arch and cleft widths.
Conclusions:
- Infant sleep position significantly affects maxillary arch development in infants with unilateral complete cleft lip and palate.
- Prone sleeping may lead to reduced maxillary arch and cleft dimensions, necessitating further investigation and potential clinical considerations.
Abstract:
The development of the dental arch is well designed for adaptive and compensatory growth. In this study, the relationship between the sleep position and dental arch development was investigated. A group of 42 infants with unilateral complete cleft lip and palate with either prone (16) or supine (26) sleep position were seen in the craniofacial center. All infants were less than 1 month of age at the initial visit. Dental impressions of the maxillary arch were taken at the initial visit and just before cheiloplasty. Ten arch dimensions were measured in each dental cast and the longitudinal change in each dimension was compared between the prone sleep group and the supine sleep group. Statistically significant changes were detected in the growth rate of the following dimensions: intercanine width, intertuberosity width, alveolar cleft width, anterior cleft width, and posterior cleft width. This study indicated that sleep position affected maxillary arch development. Infants sleeping in the prone sleep position tended to have narrower arch width and cleft width.
