Characteristics of cracks in posterior teeth and factors associated with symptoms: a cross-sectional practice-based observational study.
Observational study in Australian dental journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCracks in teeth are the third most common reason for tooth loss. The primary aim of this study was to identify the patient-specific and tooth-specific characteristics of individuals who presented to a private general dental practice with cracked posterior teeth. The secondary aim was to explore the relationship between the above characteristics and investigate their influence on signs and symptoms. MATERIALS AND
methodsA total of 147 records were analysed in terms of patient-specific, tooth-specific and crack-specific characteristics. Initial data analysis involved the use of descriptive statistics and chi-square tests. Stepwise logistic regression was used for model building, and further data analysis was performed using binomial and multinomial logistic regression.
resultsMost cracked teeth were asymptomatic (55.1%) and were not visible before removal of restoration. Unrestored marginal ridges (OR2.89), cracks visible before restoration removal (OR3.04) and cracks involving both the body and cusps of teeth (OR3.11) were associated with cold sensitivity. Not all cracked teeth were positive for the bite test. Molar teeth (OR8.79) and those with amalgam restoration (OR4.81) were associated with intersecting cracks.
conclusionThe presentation of teeth with cracks in general dental practice seems to differ from that reported in the literature from specialist practice.
